##### Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

# Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
4. Eventually you have to stop drinking. It comes down to one of two possibilities:
• You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
• You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
9. I think I got sidetracked here.
Lessons learned?
• You can't reasonably invoke "Satoshi's Vision" and simultaneously reject the Lightning Network because it's not onchain. Satoshi's Vision included a half-assed implementation of payment channels with nSequence, where the onchain transaction represented multiple logical payments, exactly what modern offchain techniques do (except modern offchain techniques actually work). nSequence (the field, but not its modern meaning) has been in Bitcoin since BitCoin For Windows Alpha 0.1.0. And its original intent was payment channels. You can't get nearer to Satoshi's Vision than being a field that Satoshi personally added to transactions on the very first public release of the BitCoin software, like srsly.
• Miners can totally bypass mempool rules. In fact, the reason why nSequence has been repurposed to indicate "optional" replace-by-fee is because miners are already incentivized by the nSequence system to always follow replace-by-fee anyway. I mean, what do you think those drinks you passed to Jihan Wu are, other than the fee you pay him to mine a specific version of your transaction?
• Satoshi made mistakes. The original design for nSequence is one of them. Today, we no longer use nSequence in this way. So diverging from Satoshi's original design is part and parcel of Bitcoin development, because over time, we learn new lessons that Satoshi never knew about. Satoshi was an important landmark in this technology. He will not be the last, or most important, that we will remember in the future: he will only be the first.

# Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
2. You sign the transaction and pass it to the bartender, who serves your first drink.
3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
4. At the end:
• If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
• If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
• If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?
• Payback's a bitch.
• Transaction malleability is a bitchier bitch. It's why we needed to fix the bug in SegWit. Sure, MtGox claimed they were attacked this way because someone kept messing with their transaction signatures and thus they lost track of where their funds went, but really, the bigger impetus for fixing transaction malleability was to support payment channels.
• Yes, including the signatures in the hash that ultimately defines the txid was a mistake. Satoshi made a lot of those. So we're just reiterating the lesson "Satoshi was not an infinite being of infinite wisdom" here. Satoshi just gets a pass because of how awesome Bitcoin is.

# CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

# Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

# Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
• Bidirectional.
• No time limit.
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
• You have to store all the revocation keys of a channel. This implies you are storing 1 revocation key for every channel update, so if you perform millions of updates over your entire lifetime, you'd be storing several megabytes of keys, for only a single channel. RustyReddit fixed this by requiring that the revocation keys be generated from a "Seed" revocation key, and every key is just the application of SHA256 on that key, repeatedly. For example, suppose I tell you that my first revocation key is SHA256(SHA256(seed)). You can store that in O(1) space. Then for the next revocation, I tell you SHA256(seed). From SHA256(key), you yourself can compute SHA256(SHA256(seed)) (i.e. the previous revocation key). So you can remember just the most recent revocation key, and from there you'd be able to compute every previous revocation key. When you start a channel, you perform SHA256 on your seed for several million times, then use the result as the first revocation key, removing one layer of SHA256 for every revocation key you need to generate. RustyReddit not only came up with this, but also suggested an efficient O(log n) storage structure, the shachain, so that you can quickly look up any revocation key in the past in case of a breach. People no longer really talk about this O(n) revocation storage problem anymore because it was solved very very well by this mechanism.
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.
Lessons learned?
• We can decentralize if we try hard enough!
• "Hubs bad" can be made "hubs good" if everybody is a hub.
• Smart people can solve problems. It's kinda why they're smart.

# Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.
Lessons learned?
• Bitcoin offchain scaling is more powerful than you ever thought.

##### WSB101 - THE BOOK OF YOLO: BEGINNERS GUIDE TO TRADING LIKE A DEGENERATE AND EVERYTHING WSB

The Book of Yolo: COMPLETE GUIDE TO WSB
The goal of this is to actually create something that all of you WSB newbies can read - because we’re all tired of seeing the endless wave of uninformed and unavoidable stupidity from those who have never touched the stock market. CALLING ALL NEWFAGS AND NORMIES.
If you can’t read, GFY now.
Now that we will be on the popular section of reddit, this has become pertinent. WSB can't avoid newcomers, so we might as well explain how the clock ticks here. This one is for you all.
This is to serve as a reference what values we hold, what instruments we use, and as a general place to educated the uneducated.
First off, this is the LEAST helpful stock market-based community for newcomers. Sarcastic answers are the only thing of true value here. It isn't a place to learn, but a place to plan out where you will dock your yacht. Newcomers are usually berated upon asking the inevitable stupid questions that they could learn slowly from reading here, or just using a damn search engine. Instead of embarrassing yourself here, you now have the opportunity to read this and get what we’re all rambling about.
This will help you understand what to expect if you make the decision to undertake a WSB style trading career, so you can stay here and contribute to the yolo lifestyle or otherwise GFY.
I will edit in any suggestions that our frequenting users or mods want to add to this as well.
To begin: Here are our topics for WSB101
-Basics (Equities/Stocks)
;
-ETF's
;
-Options
;
;
-SubCulture
;
BASICS/EQUTIES Skip if you understand basic stock stuff
Okay, so what is an equity/stock? An equity is essentially what you’d think of as your “vanilla” trading tool. They move up or down depending on market forces, and can range from pennies to thousands of dollars per share. To explain how stocks work, let's define a few terms.
Volume: The number of shares of stock traded during a particular time period, normally measured in average daily trading volume.
Bid Price: The current price in which someone wants to buy at
Ask Price:The current price in which someone wants to sell at
Volatility: The WSB favorite. Volatility is referring to the price movements of a stock as a whole. The higher the volatility, the more the stock is moving up or down. Highly volatile stocks are ones with extreme daily up and down movements and wide intraday trading ranges.
Margin: A margin account lets a person borrow money (take out a loan essentially) from a broker to purchase an investment. The difference between the amount of the loan, and the price of the securities, is called the margin. Margin is one of WSB’s popular instruments of wealth and destruction.
Dividend: This is a portion of a company’s earnings that is paid to shareholders, or people that own hat company’s stock, on a quarterly or annual basis. Not all companies do this.
PPS: Acronym for “Price per Share”
Moving Average: A stock’s average price-per-share during a specific period of time.
Bullish: Expecting the stock to go up
Bearish: Expecting the stock to go down
Any raised hands can redirect themselves to here:
Now that these terms are defined, let's move into the details of why this is even useful. Most people know what a stock is, but how and why stocks move is a different story. The stock market is essentially a big virtualization of supply and demand - meaning that usually high positive volume creates upwards movement in the PPS, where high negative volume does the opposite. This creates a trader’s opportunity; Generally, the most effective time to buy or sell is where the candlesticks (volume data) are thinning out. When you are ready to take an entry point or execute an exit point, waiting till the volatility (candlesticks) thin out is one method to give you best trade possible.
WSB FAVORITE EQUITIES: Of many equities, WSB favors the riskier ones - but avoiding penny stocks is a policy.
AMD - CEO Lisa Su, Next Gen Processors, chips, graphics. It’s the gamers gambit. Up roughly 1400% as of 2/7/2017 since WSB first mentioned it
NVDA - AMD’s sister? Mother? Daddy? Who knows. NVDA has been a sexy semiconductor leader. Is up 400% since gaining traction on WSB.
FNMA / pfds - Mnunchin, Trump, Big fat fannies. Get your self deep in the fannie. We all want it. WSB 10 bagger candidate for reforming the housing market. WSB holds a large cumulative position that can be seen below. Also a good read is the beginners guide to FNMA. Any post by u/NOVACPA is very often VERY informative on FMNA/pfds.
ARRY - A biotech champion that prevailed after a lot of failures and huge losses in the biotech sector. Dark times for WSB. Up ~300% since getting traction on the subreddit.
TWTR - WSB likes to buy put option contracts on her. Exemplary of a social media platform that is unable to monetize itself.
TSLA - Maybe not unanimously a favorite, but loved for it’s sexy volatility, Elon Musk, and ridiculously expensive options.
GILD - A Shkreli pump and dump? The greatest large cap pharma recovery of all time? Who knows. Martin took the time to make a post on this reddit and it is up $5 dollars since. ETF'S Welcome to the world of investing made easy. Exchange traded funds (etfs) are devices that can be traded like stocks, but often track the value of many companies by investing in their listed assets accordingly. Specifically, An ETF, or exchange traded fund, is a marketable security that tracks an index, a commodity, bonds, or a basket of assets like an index fund. Unlike mutual funds, an ETF trades like a common stock on a stock exchange. ETFs experience price changes throughout the day as they are bought and sold. ETFs typically have higher daily liquidity and lower fees than mutual fund shares, making them an attractive alternative for individual investors. ETF’s come in beautiful and delicious varieties, often with a BEAR form and a BULL form of each; but the most delicious to WSB are the 3x etf’s. A 3x ETF is one in which the underlying movement of the ETF is leveraged 3:1. Meaning for every movement within the underlying index or stocks, the 3x ETF moves well.... 3x as much.. WSB FAVORITE AND USEFUL ETF’S: JNUG - 3x Gold Miner Bull - A hit or miss, has extreme intraday movements and essentially tracks GDX (gold miner’s index). Jnug will usually move with a pretty strong correlation to gold, which is affected by the mentioning of rate hikes (negatively), movement of the US dollar (inversely), uncertainty (positively), and supply and demand. NUGT - Jnug with a different price tag JDST - The inverse 3x etf of JNUG - or the bear etf. It does almost exactly the opposite movements of JNUG by the tick. Moves for the same reasons, but obviously opposite directions. DUST - Jdst with a different price tag. UGAZ - Natural Gas 3x Bull ETF - essentially tracks the price value of the commodity Natural Gas, but more specifically the S&P GSCI Natural Gas Index ER. The index comprises futures contracts on a single commodity and is calculated according to the methodology of the S&P GSCI Index. Natural gas is most affected by Weather temperature conditions (use your brain), petroleum prices, and broader economic conditions. DGAZ - Inverse of UGAZ UWT - Crude Oil Bull 3x ETF - extreme intraday movements, closely follows the price of oil. More specifically, it tracks futures. UWT seeks to replicate, net of expenses, three times of the S&P GSCI® Crude Oil Index ER. The index tracks a hypothetical position in the nearest-to-expiration NYMEX light sweet crude oil futures contract, which is rolled each month into the futures contract expiring in the next month. The value of the index fluctuates with changes in the price of the relevant NYMEX light sweet crude oil futures contracts. DWT - Inverse of UWT FAS - Financial Bull, specifically FAS seeks daily investment results, before fees and expenses, of 300% of the performance of the Russell 1000 ® Financial Services Index. The fund creates long positions by investing at least 80% of its assets in the securities that comprise the Russell 1000 ® Financial Services Index and/or financial instruments that provide leveraged and unleveraged exposure to the index. Can be used when bullish on US financial services - so banks, lenders, etc. FAZ - Inverse of FAS UPRO - S&P500 Bull 3x ETF, essentially tracks the S&P500 and multiplies it’s returns by 3x. BRZU - Tracks Brazil (in its most basic form). It creates long positions in the MSCI Brazil 25/50 Index. LABU - Tracks the Biotech sector, or specifically 300% of the performance of the S&P Biotechnology Select Industry Index ("index"). It should be noted that LABU has doubled since just before the election of Donald Trump. LABD - Inverse of LABU RUSL - roughly creates 300% of the performance of the MVIS Russia Index. RUSS - Inverse of RUSL SPY - Tracks the S&P500, but is not 3x. OPTIONS: Alright, so half you are going to understand this, and half of you are not. Pull up an options chain now on any stock (penny stocks and specific stocks do not have chains because of their market cap). Options are truly the ultimate way to achieve maximum risk/reward. An option is a contract that gives the buyer the right to buy or sell 100 shares of a stock at a certain price, on a certain date. This concept makes options a commodity themselves. KEY TERMS: A CALL - is the right to buy. Buying calls is taking a bullish position in its most extreme form. A PUT - is the right to sell. The underlying - is the stock that the option is covering i.e. AAPL, GOOG, AMZN Strike Price - the price at which a put or call option can be exercised. ITM, In the money - In the money means that a call option's strike price is below the market price of the underlying asset or that the strike price of a put option is above the market price of the underlying asset. Being in the money does not mean you will profit, it just means the option is worth exercising. OTM, Out of the money - a call option with a strike price that is higher than the market price of the underlying asset, or a put option with a strike price that is lower than the market price of the underlying asset. ATM - At the money - Strike price at the same price as the underlying Expiration - Expiries for options are every friday of every week usually, with exceptions such as every month, or every other day - depending on the underlying. SPY and SPX are great examples of very active option chains with expiries every other day. On the expiry date or any time before (with american options), an option can be, but doesn’t have to be exercised, meaning the holder of the option can use it to buy or sell shares of the underlying stock at the strike price. Most people on WSB do not exercise the contracts, but merely flip them for increases in value as the underlying moves. For example, when AAPL was at 120 before its earnings report, Joe Shmoe Yolo buys 10 FEB 17th CALLS at strike 127 for .60 , each. Now .60 cents is really 60 dollars each, because the contract is multiplied by 100 (the right to 100 shares). In total, Joe Shmoe Yolo spends$600 dollars + commision on this trade. The next day, AAPL leaps to 130 upon great news. These same option contracts are now worth 3.50 each. $350 dollars per contract, times ten contracts is$3500 dollars. Joe Shmoe Yolo just turned $600 into$3500 dollars. MAGIC. Spoiler alert: Joe Shmoe Yolo was me.
That same Joe Shmoe later buys FEB 17th XOM calls at 90, hoping for similar results. However, XOM ends up never reaching anywhere close to the strike price, and the options expire worthless. Get it?
Now what determines the pricing of options?
OPTION PRICING:
Below is sourced from investopedia
Intrinsic Value: The intrinsic value is the actual value of a company or an asset based on an underlying perception of its true value including all aspects of the business, in terms of both tangible and intangible factors. This value may or may not be the same as the current market value. Additionally, intrinsic value is primarily used in options pricing to indicate the amount an option is in the money.
Time Value: Time Value = Option Price - Intrinsic Value. The more time an option has until it expires, the greater the chance it will end up in the money. The time component of an option decays exponentially. The actual derivation of the time value of an option is a fairly complex equation. As a general rule, an option will lose one-third of its value during the first half of its life and two-thirds during the second half of its life. This is an important concept for securities investors because the closer you get to expiration, the more of a move in the underlying security is needed to impact the price of the option. Time value is basically the risk premium that the option seller requires to provide the option buyer the right to buy/sell the stock up to the date the option expires. It is like an insurance premium of the option; the higher the risk, the higher the cost to buy the option. Makes sense, right?
Time value is determined by the expiration date. An expiration date in derivatives is the last day that an options contract is valid. When investors buy options, the contracts gives them the right but not the obligation, to buy or sell the assets at a predetermined price, called a strike price, within a given time period, which is on or before the expiration date. If an investor chooses not to exercise that right, the option expires and becomes worthless, and the investor loses the money paid to buy it.
Volatility:
In an options pricing, you see IV. This stands for implied volatility. The higher that is, the higher the options will be priced Volatility is the extent to which the return of the underlying asset will fluctuate between now and the option's expiration. Volatility, as expressed as a percentage coefficient within option-pricing formulas, arises from daily trading activities. How volatility is measured will affect the value of the coefficient used.
Decaying Nature of Options:
Decay refers to derivative trading (i.e. options). When you sell or buy a call/put (using those two for simplicity purposes) you don't get an infinite time frame to make your dreams come true. Time is your enemy; the further out the expiration date, the less time decay there is. Time decay really hits the worst the week of expiration. Sound confusing? Say you're buying options of the stock WSB (I hope you're seeing what I did there) - and the option costs $1, the expiration is this Friday. Say today is Monday. You buy a call expecting WSB to take you to the moon and beyond. Each day the stock doesn't move closer to your strike price or remains stagnant/drops, you lose value on your option + the time decay. Meaning if it finishes closer to your strike price, your option could be worthless because of that time decay. Questions? Ask away. A great example of these factors in action is TSLA. TSLA’s options are among the most expensive for companies in its price range, why? An in the money TSLA call expiring this week is worth around$1100 per contract. Insanely expensive. But for a reason. TSLA has extreme intraday movements and calls have an implied volatility of 40.92%. Which is fairly high. In addition to that, it holds high intrinsic value / price per share, and a week of time value.
-Futures 101 - The Ultimate YOLO Guide (thanks to u/IncendiaryGames)
Okay, a lot of you have been YOLOing on faggot delights on SPY options. How would you like to trade something with the same or more leverage, 1.0 delta, and no time premium costs? Have you considered futures? What are futures? Unlike options, futures is a contract where both the buyer and seller is obligated to perform the transaction by the expiration. Conversely, in options, only the seller is obligated to perform. That means you can lose more than your investment. Originally they were used by farmers to sell future crops early and guarantee some amount of sales. Since then futures have expanded not just to commodities but currency and equity indices like the S&P 500. Why the heck would I want to trade futures? Here are the advantages: Leverage $5k is the margin requirement for most contracts. For example with the E-mini S&P 500 with 5k you're trading$120k worth of stuff. 1 contract = 500 spy shares. Some brokers offer intraday daytrading margin rates too - TD Ameritrade is 25% of the overnight margin rate($1,250.) Some brokers go as low as$500 an /ES future. SPAN Margin If 24x overnight leverage and 240x day trade leverage didn't give you a hard on there is also SPAN margin, which is like portfolio margin on steroids. The beauty of SPAN margin is you don't need a $125k+ account to be eligible. SPAN will greatly reduce your margin requirements if you hold uncorrelated or inversely correlated positions (up to an 80% discount, here is a list of groups that give discounts) and if you hedge with options. Hedge with the right option or asset and now you have up to 500x day trading margin. 23/7 and day trading Ever get in and out of an equity only to have your broker yell at you to stop doing that or deposit$25k? There is no pattern day trading restrictions on futures. Feel free to day trade and blow up your account as often as you want! You can also trade 23 hours a day. Get trading on how the S&P 500 index will react to news from China right away. Taxes No matter how long or how short you hold you always get taxed under the 60/40 rule. 60% of your profit from futures will be taxed as a long term gain and 40% will be taxed as short term gain. No wash sales. Trade your hearts out. Just remember holding past Dec 31st will treat you as if you closed all your positions that day and you'll be taxed on unrealized gains. Long/Short No need to pay interest or borrow shares as being short a future contract is being a writer, just like an options writer. Options Of course there are options. What fun would it be without options? Unlike stock options each contract gives different number of future contracts. Research what you're trading.
Ok. I'm convinced. I want to strat trading futures! What are some good strategies?
YOLO Strategies
Swing trading Trying to guess/predict/ride sudden market momentum. A low volume average day in the S&P 500 (/ES) for one contract can swing +- $500. Get it right and you can see a huge appreciation of value. /ES is usually highly liquid during regular hours with average volume of 1 million trades and usually bid-ask spreads of one tick. One approach is to buy or short in your direction and put in a stop loss to an amount you're comfortable to lose (say$200.) Since it's so liquid you'll likely be filled at or near your stop loss during the day if your trade goes against you. If you can guess the direction 50% of the time and have trades like this: trade 1 - gain $800 trade 2 - lose$200 Then you may profit over the time period. If you have a 50% chance of being wrong and losing $200 or 50% chance of being right and gaining$800 then over time you'll gain more than you lose. Also, since the present value of your futures contract is included in your margin calculation then if it goes strongly in your favor your position can quickly grow to cover its own margin and you can let it ride for a while. You'll want to be sure you enter a combo buy/short order along with a stop loss order simultaneously, like this for Thinkorswim. Futures can move suddenly and a sudden movement can make you lose a ton of money. Exploiting outdated SPAN margin guidelines There are several out of date correlations between popular futures like oil and say things like wheat that SPAN gives you margin credits on. Take whatever position you want in oil (/cl) then take the opposite in something that doesn't move much day to day with less volatility such as /w (wheat)) and your /cl and /w positions will get a 75% credit, giving you 50% more buying power on crude oil. (2 positions * .25 = 0.5). Trade your heart out on the more volatile future then when you're done close your safer future pair. SPAN is constantly changing but such a complex system definitely has its exploits. Automated/algorithmic trading For you programmer geeks out there it's really hard to algorithmic trade on small accounts due to pattern day trading rules and economies of scale with broker fees. Futures is probably the best way to get your feet wet. Join us on /algotrading if you want to explore more!
Boring safer strategies
I'm including these for completeness but these belong on /investing. Scalping With high frequency trading scalping is less guaranteed. Basically scalping is using tiny momentum as usually there are small micro patterns in futures buying and selling activity where it will rise or fall a couple of ticks. Since the notional value of each tick is $12.5 it's profitable for retail investors and small accounts to act as a market maker after fees at the smallest bid-ask spread possible. Spreads Just like you can trade spreads in options, you can trade calendar spreads in futures. Futures have contracts with different expiration dates and the prices are different for each month of expiration based on the market's expectations. You can go long or short the near month expiration and the opposite for the far month. This will hedge out any sudden market moves as that would likely affect both months. Bull markets in general tend to increase the price of the near month faster than the far month. Basically with a spread trade you're making a long term bet on bull or bear for the underlying future. Pairs trading You can go long in one future say the dow jones (/ym) and short the S&P 500 index and profit off the relative growth. This is a hedged trade as any market ups or downs will likely affect both positions with the same % value. For the past 180 days /ym - /es has been really profitable. Even if you don't do a full perfect pairs trade it is still a great option to reduce the leverage too on whatever index future you're trading so you can stay in longer or overnight. Interest rate and optimal leverage plays Since the$5k investment is equal to $120k of the S&P 500 index currently then you'll likely beat out the market by buying one future contract and putting$115k in safe treasuries or bonds or uncorrelated assets. Some people choose to leverage their stock portfolio and you can get the exact leverage ratio of liquid investments to future ratios. In probability theory the max leverage you can gain is determined by the Kelly Criterion which modeling shows indicates the S&P 500 index to be leveraged to 1.40x. Yes, you could do the same with options but even on SPY deep in the money call leaps are illiquid and have a time premium. Even today they are so deep ITM that the options you would need to use have 0 open interest and a bid-ask spread of $5 per share (so$500 per contract.) You'd need ~5 contracts per 120k so you're already eating $2.5k/$120k - 2% interest rate a year for that leverage. SPX isn't better, it's bid ask is 22 so you'd be eating $2.2k/$120k - 1.83% interest rate. It's doubtful you won't get much past the ask as its only market makers providing liquidity and guess what the market maker will do if you buy/sell the option? They will hedge with the underlying futures until their minimum profit is the risk free interest rate. Hedging Going long and short in various non correlated or negatively correlated assets to seek out a high sharpe ratio and have a higher risk free return that is market neutral. Basic hedge fund stuff. The variety and price efficiency of futures makes things pretty attractive in this area.
SUBCULTURE
Wallstreetbets is a community that has become infamous for the most wild west, moon or cardboard box trades on the planet earth. WSB is a place where you can take out thousand dollar loans, refinance your homes, cash advance all of your credit cards only to put it all on JNUG, and we will still love you. Your mother won't. Your father will never understand your spectrum of autism, but we will always love you. It is a uniquely beautiful community focused on praising its biggest losers as much as its biggest winners. To begin on the subculture, we should define some key moments in the sub's history.
2012: Jartek [+1] creates /wallstreetbets, and word slowly starts to ooze out. 2013: americanpegasus discovers pennies. AP has seen the light, and is a penny stock evangelist. Jartek & AP have an epic options vs pennies battle - they both lose a couple of hundred bucks, but we are entertained, and WSB is officially born. AP blows up his retirement, swears off pennies and moves onto bitcoins. 2014: fscomeau [+3] discovers options. He repeatedly bets five figures on AAPL calls before earnings. FS claims a supernatural clairvoyance of AAPL. FS then posts about his chest pains and ER visits. He finally suffers an epic loss. Is he dead? Is he alive? Is he is mother? Is he banned? Who cares? 2015: Photos from the 3rd annual meetup are posted. Where a bunch of dudes hang out on the romantic beaches of Guerrero Mexico. In a completely unrelated event, the wsb banner is changed to thousands of ejaculating dicks. Modpocalypse occurs. Hundreds of random users are added as moderators for a few months. None of the new mods can change the CSS. The constant whining about how "wsb isn't what it used to be" continues. Someone attempts to show how selling covered calls is idiot proof, but gets lazy, bets all six figures on Apple, and suffers significant losses. Robinhood gets popular. Should you buy one share of AMZN or one share of GOOGL? Who gives a fuck. 2016: Everyone starts saying "go fuck yourself." Except me. Because I am what I am. And if you don't like it, you can all go fuck yourselves. u/World_Chaos performs one of the more impressive yolo's of the sub, starting with 900 dollars, and turning it into 55k. https://www.reddit.com/wallstreetbets/comments/414blh/yofuckinglo_900_to_55k_in_12_days/?ref=share&ref_source=link 2017: u/fscomeau preforms what he calls "The Final Yolo", a 300k trade against AAPL before earnings (that I, u/thor303456 inversed), supposedly supposed to net fscomeau 2.5 million or so, in which he will finally stop trading. FSC is featured on several market related articles and newspapers, showing up on yahoo, etc. Later we find proof during his livestream of AAPL earnings that he was paper trading. Even later, FSC writes a near 200 page book called "Wolfie Has Fallen" describing how he trolled the entire internet, some following him into that AAPL trade. Martin Shkreli visits the sub and proclaims that GILD pharma is worth over $100 a share and is deeply undervalued. KEY FIGURES: Donald J Trump - He is the Marmalade Manchurian, the Tangerine Tycoon, and our spray tan Stalin. Unbelievable night of election. WSB demographics show a primarily capitalist and right wing (or at least joking to be so) point of view, and thus we are generally pro trump. In actuality though, WSB is focused on pro-market, which Trump happens to be. u/Jartek - Founder of the sub, original yoloer. Believe he has retired from reddit for the most part. Mostly inactive. u/Fscomeau - The Canadian as some call him, and perhaps one of the most profound internet trolls of 2016-2017. A French-Canadian trader who deals with mostly options. The man has been called "The Great Inverse", and for a good reason. Nearly all of the trades or statements he made on WSB were completely wrong or mostly wrong. Truly the strongest technical indicator. Martin Shkreli - An idol to many WSBers, Martin stands as the master of the biotech sector. A very debated character for very stupid reasons. Martin regularly tweets about the stock market, occasionally does a youtube channel, and livestreams fairly regularly. u/theycallme1 - Educated trader, and mod of WSB. Roasts people often and roasts them good. Ask him the questions that aren't stupid. One of the most active mods. u/world_chaos - some fucking college student with some real net worth. Sits on 100k or so (needs verification), and was an inspiring yoloer to all, with his 900 to 55k yolo with options. Lingo, Terminology, and Nomenclature: The Faggots Delights - Truly the most suicidal, yet clearest shot to the moon. This term is usually used to define either weekly, or daily option plays on the SPY/SPX. Some users trade them very profitably, such as u/MRPguy and many in the past. Cuck - Truly the worst thing you could be. A cuck is a man who likes watching his wife/girlfriend fuck other guys. Weak, spineless, and a term often throw around here. The YOLO - You only live once. This is something that is, and should be realized as undeniably true. Why are you sitting on a 5k emergency fund that is making you less interest in a year than what I just made in 10 minutes? Why haven't you used all of the credit on your 5 credit cards or used your testicles as collateral for a loan yet? YOLO or YOLOING is as much a psychological decision to embrace absurdism, and win with everything you have while risking it all. Yolo is what it means to be a WSB trader. Bagholding or a Bagholder - When you're stuck with the most ass trade of your life, because you know it'll go back up. A bagholder is the 59 year old guy at the grocery store who won't quit his Job because he knows he only has to wait another year until he gets a return on his investment (of his life). Anyone holding SUNEQ is the definition of a bagholder. Autists - Something we embrace, something we call each other, something we all are. Autism isn't used in an offensive way as much as it is a generally accepted term that defines us. The best traders have autism because of their distance from emotion. I bet you never made it to this part of the reading because you're such a damn autist. Tendies - Tendies are what you get after you make a small amount of money. "I SOLD AMD TODAY FOR A$13 DOLLAR PROFIT, GOING TO MCD's TO GET MY TENDIES". Tendie money is usually shameful and insignificant, but at least it got you tendies. Chicken tenders at McDonalds are the least expensive for the most cholesterol.
I know some of the writing was half ass, full of errors, or otherwise not the best explanation. But I believe this will serve its purpose, and maybe help to promote new ideas from moderately educated traders. WSB has very strong traders, and the most uniquely risky trading styles on the planet. Hopefully this can serve to better the overall community.
You guys are all faggots, upvote this so we can get the noobs to stop trying to bite on our cocks.
Also I'd really appreciate input on anything to add to this overall. It took my over 3 hours to write up, so I eventually grew tired and probably have missing spots.
Enjoy your time here at WSB.
EDIT: Added a shit ton of stuff, fixed errors. THANKS FOR ALL OF YOUR INPUT, ACTUALLY MAKING WSB GREAT AGAIN
MODS: Can we make this editable by others mods or something? My fingers aren't enough. Seems like this could serve as a good "official" thing. Paging u/theycallme1 u/CHAINSAW_VASECTOMY etc

### DigiByte

What are cryptocurrencies?
Cryptocurrencies are peer to peer technology protocols which rely on the block-chain; a system of decentralized record keeping which allows people to exchange unmodifiable and indestructible information “coins,” globally in little to no time with little to no fees – this translates into the exchange of value as these coins cannot be counterfeit nor stolen. This concept was started by Satoshi Nakamoto (allegedly a pseudonym for a single man or organization) whom described and coded Bitcoin in 2009.
What is DigiByte?
DigiByte (DGB) is a cryptocurrency like Bitcoin. It is also a decentralized applications protocol in a similar fashion to Neo or Ethereum.
DigiByte was founded and created by Jared Tate in 2014. DigiByte allows for fast (virtually instant) and low cost (virtually free) transactions. DigiByte is hard capped at 21 billion coins which will ever be mined, over a period of 21 years. DigiByte was never an ICO and was mined/created in the same way that Bitcoin or Litecoin initially were.
DigiByte is the fastest UTXO PoW scalable block-chain in the world. We’ll cover what this really means down below.
DigiByte has put forth and applied solutions to many of the problems that have plagued Bitcoin and cryptocurrencies in general – those being:
• Maintaining decentralisation.
• Maintaining low fees.
• Maintaining fast transaction times.
• Maintaining robust security + the immutable ledger.
• And most importantly assuring massive scalability on chain.
We will address these point by point in the subsequent sections.
The DigiByte Protocol
DigiByte maintains these properties through use of various technological innovations which we will briefly address below.
Why so many coins? 21 Billion
When initially conceived Bitcoin was the first of a kind! And came into the hands of a few! The beginnings of a coin such as Bitcoin were difficult, it had to go through a lot of initial growth pains which following coins did not have to face. It is for this reason among others why I believe Bitcoin was capped at 21 million; and why today it has thus secured a place as digital gold.
When Bitcoin was first invented no one knew anything about cryptocurrencies, for the inventor to get them out to the public he would have to give them away. This is how the first Bitcoins were probably passed on, for free! But then as interest grew so did the community. For them to be able to build something and create something which could go on to have actual value, it would have to go through a steady growth phase. Therefore, the control of inflation through mining was extremely important. Also, why the cap for Bitcoin was probably set so low - to allow these coins to amass value without being destroyed by inflation (from mining) in the same way fiat is today! In my mind Satoshi Nakamoto knew what he was doing when setting it at 21 million BTC and must have known and even anticipated others would take his design and build on top of it.
At DigiByte, we are that better design and capped at 21 billion. That's 1000 times larger than the supply of Bitcoin. Why though? Why is the cap on DigiByte so much higher than that of Bitcoin? Because DigiByte was conceived to be used not as a digital gold, nor as any sort of commodity, but as a real currency!
Today on planet Earth, we are approximately 7.6 billion people. If each person should want or need to use and live off Bitcoin; then equally split at best each person could only own 0.00276315789 BTC. The market cap for all the money on the whole planet today is estimated to have recently passed 80 trillion dollars. That means that each whole unit of Bitcoin would be worth approximately $3,809,523.81!$3,809,523.81
This is of course in an extreme case where everyone used Bitcoin for everything. But even in a more conservative scenario the fact remains that with such a low supply each unit of a Bitcoin would become absurdly expensive if not inaccessible to most. Imagine trying to buy anything under a dollar!
Not only would using Bitcoin as an everyday currency be a logistical nightmare but it would be nigh impossible. For each Satoshi of a Bitcoin would be worth much, much, more than what is realistically manageable.
This is where DigiByte comes in and where it shines. DigiByte aims to be used world-wide as an international currency! Not to be hoarded in the same way Bitcoin is. If we were to do some of the same calculations with DigiByte we'd find that the numbers are a lot more reasonable.
At 7.6 billion people, each person could own 2.76315789474 DGB. Each whole unit of DGB would be worth approximately $3,809.52.$3,809.52
This is much more manageable and remember in an extreme case where everyone used DigiByte for everything! I don't expect this to happen anytime soon, but with the supply of DigiByte it would allow us to live and transact in a much more realistic and fluid fashion. Without having to divide large numbers on our phone's calculator to understand how much we owe for that cup of coffee! With DigiByte it's simple, coffee cost 1.5 DGB, the cinema 2.8 DGB, a plane ticket 500 DGB!
There is a reason for DigiByte's large supply, and it is a good one!
Decentralisation
Decentralisation is an important concept for the block-chain and cryptocurrencies in general. This allows for a system which cannot be controlled nor manipulated no matter how large the organization in play or their intentions. DigiByte’s chain remains out of the reach of even the most powerful government. This allows for people to transact freely and openly without fear of censorship.
Decentralisation on the DigiByte block-chain is assured by having an accessible and fair mining protocol in place – this is the multi-algorithm (MultiAlgo) approach. We believe that all should have access to DigiByte whether through purchase or by mining. Therefore, DigiByte is minable not only on dedicated mining hardware such as Antminers, but also through use of conventional graphics cards. The multi-algorithm approach allows for users to mine on a variety of hardware types through use of one of the 5 mining algorithms supported by DigiByte. Those being:
• Scrypt
• SHA256
• Qubit
• Skein
• Groestl
Please note that these mining algorithms are modified and updated from time to time to assure complete decentralisation and thus ultimate security.
The problem with using only one mining algorithm such as Bitcoin or Litecoin do is that this allows for people to continually amass mining hardware and hash power. The more hash power one has, the more one can collect more. This leads to a cycle of centralisation and the creation of mining centres. It is known that a massive portion of all hash power in Bitcoin comes from China. This kind of centralisation is a natural tendency as it is cheaper for large organisations to set up in countries with inexpensive electricity and other such advantages which may be unavailable to the average miner.
DigiByte mitigates this problem with the use of multiple algorithms. It allows for miners with many different kinds of hardware to mine the same coin on an even playing field. Mining difficulty is set relative to the mining algorithm used. This allows for those with dedicated mining rigs to mine alongside those with more modest machines – and all secure the DigiByte chain while maintaining decentralisation.
Low Fees
Low fees are maintained in DigiByte thanks to the MultiAlgo approach working in conjunction with MultiShield (originally known as DigiShield). MultiShield calls for block difficulty readjustment between every single block on the chain; currently blocks last 15 seconds. This continuous difficulty readjustment allows us to combat any bad actors which may wish to manipulate the DigiByte chain.
Manipulation may be done by a large pool or a single entity with a great amount of hash power mining blocks on the chain; thus, increasing the difficulty of the chain. In some coins such as Bitcoin or Litecoin difficulty is readjusted every 2016 blocks at approximately 10mins each and 2mins respectively. Meaning that Bitcoin’s difficulty is readjusted about every two weeks. This system can allow for large bad actors to mine a coin and then abandon it, leaving it with a difficulty level far too high for the present hash rate – and so transactions can be frozen, and the chain stopped until there is a difficulty readjustment and or enough hash power to mine the chain. In such a case users may be faced with a choice - pay exorbitant fees or have their transactions frozen. In an extreme case the whole chain could be frozen completely for extended periods of time.
DigiByte does not face this problem as its difficulty is readjusted per block every 15 seconds. This innovation was a technological breakthrough and was adopted by several other coins in the cryptocurrency environment such as Dogecoin, Z-Cash, Ubiq, Monacoin, and Bitcoin Gold.
This difficulty readjustment along with the MultiAlgo approach allows DigiByte to maintain the lowest fees of any UTXO – PoW – chain in the world. Currently fees on the DigiByte block-chain are at about 0.0001 DGB per transaction of 100 000 DGB sent. This depends on the amount sent and currently 100 000 DGB are worth around $2000.00 with the fee being less than 0.000002 cents. It would take 500 000 transactions of 100 000 DGB to equal 1 penny’s worth. This was tested on a Ledger Nano S set to the low fees setting. Fast transaction times Fast transactions are ensured by the conjunctive use of the two aforementioned technology protocols. The use of MultiShield and MultiAlgo allows the mining of the DigiByte chain to always be profitable and thus there is always someone mining your transactions. MultiAlgo allows there to a greater amount of hash power spread world-wide, this along with 15 second block times allows for transactions to be near instantaneous. This speed is also ensured by the use DigiSpeed. DigiSpeed is the protocol by which the DigiByte chain will decrease block timing gradually. Initially DigiByte started with 30 second block times in 2014; which today are set at 15 seconds. This decrease will allow for ever faster and ever more transactions per block. Robust security + The Immutable Ledger At the core of cryptocurrency security is decentralisation. As stated before decentralisation is ensured on the DigiByte block chain by use of the MultiAlgo approach. Each algorithm in the MultiAlgo approach of DigiByte is only allowed about 20% of all new blocks. This in conjunction with MultiShield allows for DigiByte to be the most secure, most reliable, and fastest UTXO block chain on the planet. This means that DigiByte is a proof of work (PoW) block-chain where all transactional activities are stored on the immutable public ledger world-wide. In DigiByte there is no need for the Lightning protocol (although we have it) nor sidechains to scale, and thus we get to keep PoW’s security. There are many great debates as to the robustness or cleanliness of PoW. The fact remains that PoW block-chains remain the only systems in human history which have never been hacked and thus their security is maximal. For an attacker to divert the DigiByte chain they would need to control over 93% of all the hashrate on one algorithm and 51% of the other four. And so DigiByte is immune to the infamous 51% attack to which Bitcoin and Litecoin are vulnerable. Moreover, the DigiByte block-chain is currently spread over 200 000 plus servers, computers, phones, and other machines world-wide. The fact is that DigiByte is one of the easiest to mine coins there is – this is greatly aided by the recent release of the one click miner. This allows for ever greater decentralisation which in turn assures that there is no single point of failure and the chain is thus virtually un-attackable. On Chain Scalability The biggest barrier for block-chains today is scalability. Visa the credit card company can handle around 2000 transactions per second (TPS) today. This allows them to ensure customer security and transactional rates nation-wide. Bitcoin currently sits at around 7 TPS and Litecoin at 28 TPS (56 TPS with SegWit). All the technological innovations I’ve mentioned above come together to allow for DigiByte to be the fastest PoW block-chain in the world and the most scalable. DigiByte is scalable because of DigiSpeed, the protocol through which block times are decreased and block sizes are increased. It is known that a simple increase in block size can increase the TPS of any block-chain, such is the case with Bitcoin Cash. This is however not scalable. The reason a simple increase in block size is not scalable is because it would eventually lead to some if not a great amount of centralization. This centralization occurs because larger block sizes mean that storage costs and thus hardware cost for miners increases. This increase along with full blocks – meaning many transactions occurring on the chain – will inevitably bar out the average miner after difficulty increases and mining centres consolidate. Hardware cost, and storage costs decrease over time following Moore’s law and DigiByte adheres to it perfectly. DigiSpeed calls for the increase in block sizes and decrease in block timing every two years by a factor of two. This means that originally DigiByte’s block sizes were 1 MB at 30 seconds each at inception in 2014. In 2016 DigiByte increased block size by two and decreased block timing by the same factor. Perfectly following Moore’s law. Moore’s law dictates that in general hardware increases in power by a factor of two while halving in cost every year. This would allow for DigiByte to scale at a steady rate and for people to adopt new hardware at an equally steady rate and reasonable expense. Thus so, the average miner can continue to mine DigiByte on his algorithm of choice with entry level hardware. DigiByte was one of the first block chains to adopt segregated witness (SegWit in 2017) a protocol whereby a part of transactional data is removed and stored elsewhere to decrease transaction data weight and thus increase scalability and speed. This allows us to fit more transactions per block which does not increase in size! DigiByte currently sits at 560 TPS and could scale to over 280 000 TPS by 2035. This dwarfs any of the TPS capacities; even projected/possible capacities of some coins and even private companies. In essence DigiByte could scale worldwide today and still be reliable and robust. DigiByte could even handle the cumulative transactions of all the top 50 coins in coinmarketcap.com and still run smoothly and below capacity. In fact, to max out DigiByte’s actual maximum capacity (today at 560 TPS) you would have to take all these transactions and multiply them by a factor of 10! Oher Uses for DigiByte Note that DigiByte is not only to be used as a currency. Its immense robustness, security and scalability make it ideal for building decentralised applications (DAPPS) which it can host. DigiByte can in fact host DAPPS and even centralised versions which rely on the chain which are known as Digi-Apps. This application layer is also accompanied by a smart contract layer. Thus, DigiByte could host several Crypto Kitties games and more without freezing out or increasing transaction costs for the end user. Currently there are various DAPPS being built on the DigiByte block-chain, these are done independently of the DigiByte core team. These companies are simply using the DigiByte block-chain as a utility much in the same way one uses a road to get to work. One such example is Loly – a Tinderesque consensual dating application. DigiByte also hosts a variety of other platform projects such as the following: • DigiPay – A jqeury online payment protocol portal web plugin. • DigiByte DigiHash - The official DigiByte foundation mining pool. • DigiByte Digi-ID – A platform for identity verification to be used in lieu of two factor authentication and passwords. • DigiByte Playground – An interactive Javascript sandbox for developers. • DigiByte Emma AI – A DigiByte interactive artificial intelligence assistant. • DigiByte DigiMan – A web browser plugin to be used as a security layer two protocol. • DigiByte DigiSeeder – A background seeding service which assures all wallets quickly find other peers in the network. • DigiByte DigiMessenger – A ground-breaking messaging application built on top of DigiByte which features robust and virtually unbreakable encryption. • DigiByte OneClickMiner – An easy to set up application which allows users to quickly start mining DigiByte on their home machines. • DigiByte DigiBot – A telegram bot for users to interact with DigiByte and more. The DigiByte Foundation As previously mentioned DigiByte was not an ICO. The DigiByte foundation was established in 2017 by founder Jared Tate. Its purpose is as a non-profit organization dedicated to supporting and developing the DigiByte block-chain. DigiByte is a community effort and a community coin, to be treated as a public resource as water or air. Know that anyone can work on DigiByte, anyone can create, and do as they wish. It is a permissionless system which encourages innovation and creation. If you have an idea and or would like to get help on your project do not hesitate to contact the DigiByte foundation either through the official website and or the telegram developer’s channel. For this reason, it is ever more important to note that the DigiByte foundation cannot exist without public support. And so, this is the reason I encourage all to donate to the foundation. All funds are used for the maintenance of DigiByte servers, marketing, and DigiByte development.

Edit - Removed Jaxx wallet. Edit - A new section was added to the article: Why so many coins? 21 Billion Edit - Adjusted max capacity of DGB's TPS - Note it's actually larger than I initially calculated. Edit – Grammar and format readjustment Hello, I hope you’ve enjoyed my article, I originally wrote this for the reddit sub-wiki where it generally will most likely, probably not, get a lot of attention. So instead I've decided to make this sort of an introductory post, an open letter, to any newcomers to DGB or for those whom are just curious. I tried to cover every aspect of DGB, but of course I may have forgotten something! Please leave a comment down below and tell me why you're in DGB? What convinced you? Me it's the decentralised PoW that really convinced me. Plus, just that transaction speed and virtually no fees! Made my mouth water! -Dereck de Mézquita I'm a student typing this stuff on my free time, help me pay my debts? Thank you!

We breakdown the top five stories in five sentences or less. No BS. No Bias. https://aroundtheblock.news/ ____________________________________________ 1) Nouriel Roubini and Vitalik face-off: debate coming soon? Following Roubini’s accusations and Twitter tirade against Vitalik Buterin, he posted that he would be “happy to have a live debate the Ethereum founder,” on the condition that they both agree on a moderator who should not be a “biased shill,” and specifically not Forbes contributor Laura Shin. Buterin responded, nominating Kevin Pham: “Can’t get more fair than someone equally 100% biased against both of us!” 2) Tether trouble: millions of USDT exit Bitfinex, stablecoin falls below$0.90
Bitfinex had a rough week: a pseudonymous author claimed they were “insolvent,” millions of tethers (USDT) were seen exiting Bitfinex, fiat deposits and withdrawals were frozen, and the trade value of USDT fell below 90 cents. The value of USDT has been stabilizing since and the exchange has released a blog post denying the insolvency rumours claimed in a Medium post that has since been taken down.
“Bitfinex is not insolvent, and a constant stream of Medium articles claiming otherwise is not going to change this,” they wrote. As for the fiat freeze, they said there are still complications but they are doing their best to minimize waiting times.
3) SEC comes after another ICO, which falsely claimed it had SEC approval
In a release, the SEC said it “has obtained an emergency court order halting a planned initial coin offering,” as well as any ongoing pre-ICO sales by a company called Blockvest, which created the token BLV. According to the release, the company falsely claimed to be approved by the SEC.
“Blockvest and Ringgold, who also goes by the name Rasool Abdul Rahim El, were using the SEC seal without permission, a violation of federal law, and falsely claiming their crypto fund was ‘licensed and regulated.’ The complaint also alleges Ringgold promoted the ICO with a fake agency he created called the ‘Blockchain Exchange Commission,’ using a graphic similar to the SEC’s seal and the same address as SEC headquarters.”
4) LTC founder Charlie Lee interested in Monero, may “eventually have to step away from Litecoin”
In an interview with cryptocurrency prime dealer SFOX, Litecoin founder Charlie Lee said: “Bitcoin is obviously the soundest form of money around, and Litecoin, I would say, is the second soundest. Another project that I’m interested in as Monero: I think a bit of privacy and fungibility is something that’s missing from Bitcoin and Litecoin, and it’s very much needed.”
“Obviously, Litecoin is more centralized than Bitcoin. If anyone wants to target Litecoin, they could attack me. That’s something that definitely could be improved. So I think that moving forward, I’ll eventually have to step away from Litecoin”.
5) Confirmed: Coinbase’s crypto index fund is closing down
A Coinbase spokesperson has reportedly confirmed that the cryptocurrency exchange is shutting down the Coinbase Index Fund by the end of October, four months since it went live, according to a CoinDesk article.
“After assessing demand from retail, accredited and institutional investors, Coinbase has decided to shut down Coinbase Index Fund. We will focus on providing diversified exposure to all investors through Coinbase Bundle,” the spokesperson said

1200s-1300s During the 13th century bankers from north Italy, collectively known as Lombards, gradually replace the Jews in their traditional role as money-lenders to the rich and powerful. – Florence, Venice and Genoa - The Bardi and Peruzzi Families dominated banking in 14th century Florence, establishing branches in many other parts of Europe
1200 By the time Marco Polo visited China they’d move from coins to paper money, who introduced the concept to Europe. An inscription warned, "All counterfeiters will be decapitated." Before the use of paper, the Chinese used coins that were circular, with a rectangular hole in the middle. Several coins could be strung together on a rope. Merchants in China, if they became rich enough, found that their strings of coins were too heavy to carry around easily. To solve this problem, coins were often left with a trustworthy person, and the merchant was given a slip of paper recording how much money they had with that person. Marco Polo's account of paper money during the Yuan Dynasty is the subject of a chapter of his book, The Travels of Marco Polo, titled "How the Great Kaan Causeth the Bark of Trees, Made Into Something Like Paper, to Pass for Money All Over his Country."

1577 Newspaper in Korea
1586 The Babington Plot
1590 Cabinet Noir was established in France. Its mission was to open, read and reseal letters, and great expertise was developed in the restoration of broken seals. In the knowledge that mail was being opened, correspondents began to develop systems to encrypt and decrypt their letters. The breaking of these codes gave birth to modern systematic scientific code breaking.
1600s Promissory banknotes began in London
1600s By the early 17th century banking begins also to exist in its modern sense - as a commercial service for customers rather than kings. – Late 17th century we see cheques slowly gains acceptance
The total of the money left on deposit by a bank's customers is a large sum, only a fraction of which is usually required for withdrawals. A proportion of the rest can be lent out at interest, bringing profit to the bank. When the customers later come to realize this hidden value of their unused funds, the bank's profit becomes the difference between the rates of interest paid to depositors and demanded from debtors.
The transformation from moneylenders into private banks is a gradual one during the 17th and 18th centuries. In England it is achieved by various families of goldsmiths who early in the period accept money on deposit purely for safe-keeping. Then they begin to lend some of it out. Finally, by the 18th century, they make banking their business in place of their original craft as goldsmiths.

1668 Bank of Sweden – today the 2nd oldest surviving bank
1694 First Central Bank established in the UK was the first bank to initiate the permanent issue of banknotes
Served as model for most modern central banks.
The modern banknote rests on the assumption that money is determined by a social and legal consensus. A gold coin's value is simply a reflection of the supply and demand mechanism of a society exchanging goods in a free market, as opposed to stemming from any intrinsic property of the metal. By the late 17th century, this new conceptual outlook helped to stimulate the issue of banknotes.
1700s Throughout the commercially energetic 18th century there are frequent further experiments with bank notes - deriving from a recognized need to expand the currency supply beyond the availability of precious metals.

1907 Banking Panic of 1907
The New York Stock Exchange dropped dramatically as everyone tried to get their money out of the banks at the same time across the nation. This banking panic spurred debate for banking reform. JP Morgan and others gathered to create an image of concern and stability in the face of the panic, which eventually led to the formation of the Federal Reserve. The founders of the Federal Reserve pretended like the bankers were opposed to the idea of its formation in order to mislead the public into believing that the Federal Reserve would help to regulate bankers when in fact it really gave even more power to private bankers, but in a less transparent way.

Phil Zimmermann's PGP cryptosystem and its distribution on the Internet in 1991 was the first major 'individual level' challenge to controls on export of cryptography. The growth of electronic commerce in the 1990s created additional pressure for reduced restrictions.[3] Shortly afterward, Netscape's SSL technology was widely adopted as a method for protecting credit card transactions using public key cryptography. 1990 NSFNET replaced Arpanet as backbone of the internet with more than 500k users Early 90s Dial up provided through AOL and Compuserve People were leery to use credit cards on the internet 1991 How to time-stamp a digital doc - Stornetta 1991 Phil Zimmermann releases the public key encryption program Pretty Good Privacy (PGP) along with its source code, which quickly appears on the Internet.

I have pulseeffects installed and running. I have created a few equalizer profiles. How can I toggle (enable/disable) selected profile using command line options. I know I can just click on the profile but I would like to bind that to some global key to toggle it when needed. It seems like there might be something weird going on with that blog, but I only quickly looked. Here is the idea for the ZF equalizer: Figure out the convolution matrix. convMatrix = convmtx(h, length(x)); This will be a $9 \times 7$ matrix because the input vector $\mathbf{x}$ is length 7 and the output convolution will be of length $7+3-1=9$.
