Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low

Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.

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?

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?

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:
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):
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?

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.

Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.
BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk.
Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.
A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
Using Electrum, the "Tools" menu option: "Pay to many".
Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
Draw your own conclusions based on their own words:
March 2016 - Coinbase CEO Brian Armstrong has reservations about Core

P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Do you want low tx fees, because this is how you get low tx fees

TL/DR
Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.
MEMPOOL/SEGWIT STATISTICS
BACKGROUND
On Dec 18 Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
  • SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
  • Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
  • Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
  • It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to existing wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
    Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
    Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
  • P2SH starts with "3..."
    bech32 starts with "bc1..."
Which addresses can I send from/to?
  • P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backwards compatibility
    bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
    Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
  • The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Experiment , generate more Bitcoin by buying top10 altcoins in 2020.

Experiment , generate more Bitcoin by buying top10 altcoins in 2020.
Finally i have made a decision to do this experiment generating more Bitcoins by buying shitcoins . About which i was talking on my video on YouTube in march 2019. So basically my plan was to buy some alt-coins with Bitcoin and in that way generate more Bitcoins. I have made this decision because most of the alt-coins has reached lowest points against BTC in my opinion. And proving by history they usually bounce of it. Another big reason is that Bitcoin halving is due in May 2020. This could spike up Bitcoin price and alt-coins could possible dragged with it. I cannot guarantee i will succeed but i will do an update every month or quarter on YouTube channel how am im doing with this chosen portfolio. I have a good feeling i will succeed, as i am not Bitcoin maximal and shit-coin minimalist. I am quite good at recognizing innovation. Few of my purchased coins potentially could do much better then Bitcoin price in nearest future.

https://preview.redd.it/4dionqaitra41.png?width=1302&format=png&auto=webp&s=7ca6551ab65e36c33ea3ded6c68a25f998fac4c4
So the plan is to spend 2 BTC and buy 10 alt-coins. 0.2 Bitcoin each alt-coin. I am using binance to purchase these coins and i will add them in my portfolio tracker https://www.cryptocompare.com/portfolio/ . This place is very nice where to track your crypto portfolio from desktop. I do believe 99% alt-coins are scam and will fail in future, but there also will be some who will survive. The reason i think im going to succeed is not only that these projects are useful. But i only need 1 alt-coin to do 10x in bull market against btc and the rest can fail to brake even.
My top 10 alt-coins purchased and the reasons behind it :
  • Ethereum - By dapp platform stats Ethereum is winning every other gen2-gen3 blockchains which are Tron,Eos etc in every aspect. Built Dapps, new users,existing users,volume and so on. Users and developers are the main key for s block-chain project to succeed. Ethereum has issues yes, there is not much room to grow. But there is constant development going on to increase platforms usability. Another thing is DeFi (decentralized finance) which got very popular in 2019 . Which basically brings banking to block-chain. This new turn on Ethereum is gaining momentum and growing every day. This will be huge in my opinion in 2020.

https://preview.redd.it/ou93neqjtra41.png?width=864&format=png&auto=webp&s=b098124dc7722e67da6fb1504f8dcfff4a2aba2b
  • Chainlink - Chainlink is something unique. Currently Block-chains smart contracts cannot record data on them from outside world, they can do only on chain data. Which is timestamps,block numbers, transaction value. On their own they cannot listen to outside world which is called of chain data. But Chainlink fixes this issue, feeding this information trough decentralized oracles to smart contracts. It really made this utility token very popular in 2019, because of their massive partnership with google cloud. And on top of that they already have working product and it is been used by numerous crypto projects. It currently is looking the biggest contender to fix this issue what block chains has.

https://preview.redd.it/x9w5o8tktra41.png?width=1271&format=png&auto=webp&s=4bb5edfe4a43f2a6102ed0913348077125878b5e
  • Basic attention token ( BAT) - is solving Advertisers and Content creators as myself problem ,what we have currently. For example Google collects about 40-50% add revenue from YouTube adds. Basic attention token ( BAT) solves this issue with their Brave browser. Brave browser allows you to tip your favorite content creators and block companies which collects your privacy data. So how does it work , Advertiser purchases advertisement with BAT tokens which goes to users and content creators. You actually are getting paid to watch adds. So it disables the middle man like google in this case who is taking 50% cut. Technically if Brave browser platform grows, price should increase.
  • Monero - Monero is a privacy coin. I do believe that privacy coins will be very demanded in future. As block-chains are getting bigger and bigger adoption, eventually governments will crack down on them. And will develop software which will allow them to trace and get user privacy data. This could happen already this year, as recent statements from EU leaders are they need more regulation on Crypto and block-chain. Monero is one of the oldest privacy coin out there. And these events around possibly could spike up Monero price. I don't want to hype it to much, but privacy was one of the main feature why Bitcoin was invented.
  • Neo - neo is 3rd generation blockchain similar as Ethereum. Neo comes out of China, which is one of the main reasons why im choosing this smart contract platform. Recent statement from Chinese president Xi Jinping that they have to adopt block-chain technology in their country. This statement made me very bullish on NEO. 3rd generation block-chain platforms really will kick of in 2020, just because the possibilities can be developed on them. I don't really think yet we have figured out what can be deployed on these platforms. We can see that as time goes by, new things are been figured out like DeFi, games, fundraising and many more. Also the price on NEO has drooped about 20x since all time high. And recent volume has been growing on NEO platform. So fingers cross, Neo going to bring us honey.
  • Cosmos (ATOM)
  • IOTA (MIOTA)
  • Synthetix (SNX)
  • Tezos (XTZ)
  • Cardano (ADA)

I have gone trough these projects social media channels and looked how active is the community. GitHub, is there any active development on their platform. Also is there any fundamentals and working product behind it. These are the main reasons i have picked these coins for my challenge. This is not any financial advice, i'm just looking to do a challenge/research. Is this a way to increase bitcoin in bull market by buying alt-coins. I'm playing this safe and choosing the coins from top 50 in coin-market cup. Because i do believe if coin is valuable it should at-least have some value in bear market.

Day 6: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Refer a friend to SegWit today. There's no $10 referral offer, but you'll both get lower fees and help strengthen the BTC protocol

TL/DR
Bitcoin users can help lower transaction fees and contribute to bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.

Channel should be open now
Chill05/10/2019
you all rock!
just getting that out of the way :wink:
Tron05/10/2019
Cheers everyone.
theking05/10/2019
Hi fabulous dev team!
Hans_Schmidt05/10/2019
Howdy!
Tron05/10/2019
No specific agenda today.
Questions?
Has everyone seen Zelcore wallet, and Spend app?
theDopeMedic05/10/2019
Any major development status updates that haven't been listed in #news?
Synicide05/10/2019
How was the meetup yesterday? I heard it would be recorded, it is uploaded anywhere yet?
Tron05/10/2019
And Trezor support on Mango Farm assets?
@Synicide Yes it was recorded. The Bitcoin meetup organizer has the video.
I talked about Ravencoin, but mostly about the stuff that was being built on/with/for Ravencoin.
There was about 70% overlap with folks who were at the Ravencoin meetup in March.
Synicide05/10/2019
awesome, looking forward to watching it when it's available
Tron05/10/2019
I'll hit up James and see if he's posting the video.
S1LVA | GetRavencoin.org05/10/2019
@theDopeMedic I'd follow github if youre interested in development status
Synicide05/10/2019
zelcore looks super slick. Been meaning to research its security more with the username/pw being stored on device
Chill05/10/2019
How is the progress on the restricted assets and testnet coming along? A secondary question would be about the approximate fork timeframe.
S1LVA | GetRavencoin.org05/10/2019
Has anyone heard from the community dev (BW) working on Dividends?
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Any word on BW and his progress w dividends?
@S1LVA | GetRavencoin.org LOL
Tron05/10/2019
@S1LVA | GetRavencoin.org Great question. I haven't heard.
Synicide05/10/2019
last meeting BlondFrogs said he would try to connect with BW as he was sick with the flu at the time. Maybe he has an update
S1LVA | GetRavencoin.org05/10/2019
I've tried to get in contact, but with no success.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Got a funny feeling...
Jeroz05/10/2019
Last time we left off with someone mentioning a foundation and Tron saying let’s discuss that next time iirc
kryptoshi05/10/2019
Has anyone taken a look at the merits for this proposal? Thoughts? https://medium.com/systems-nexus/modified-x16r-algorithm-proposal-for-constant-hash-rate-in-short-time-164711dd9044
Medium
Modified X16R algorithm proposal for constant hash rate in short time
Interpretation Lens V. a0.01
Tron05/10/2019
I did see it. Does anyone think this is a problem?
Synicide05/10/2019
It looks interesting... but I'm not sure what it is trying to solve. Looking at netstats, our 1 hour average block time is perfectly 1 minute
S1LVA | GetRavencoin.org05/10/2019
Last I heard from him he expressed how important finishing the code was. I wouldnt jump to conclusions on his absence within the community.
Synicide05/10/2019
x16r by nature will fluctuate, but DGW seems to be doing a good job keeping consistent block times
Tron05/10/2019
Because of relatively broad distribution across the algorithms, the block times are fairly consistent. It is possible, but very, very unlikely to get a sequence that takes up to 4x longer, but that's super rare, and only 4 minutes.
We did some timing analysis of the algorithms early on. A few are 1/2 as long as SHA-256 and some are up to 4x longer. But when you randomly select 16 it usually comes out about even.
Synicide05/10/2019
1hr avg: 1.02min - 24hr avg: 1min
I think we should focus on building, and not trying to fix what isnt necessarily broken
Tron05/10/2019
Agreed.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Agreed
Tron05/10/2019
Is everyone ok with the frequency (every other week) of this discussion?
Jeroz05/10/2019
(Added thumbs down to measure)
Tron05/10/2019
@Jeroz Did you do thumbs-up and thumbs down?
S1LVA | GetRavencoin.org05/10/2019
Seems appropriate. Its not like the devs dont poke around here and chat anyways.
Tron05/10/2019
Anything critical that we should be aware of?
Jeroz05/10/2019
When I need a dev, I poke a dev. When that dev is unavailable. I poke another one :smiley:
Hans_Schmidt05/10/2019
BlondFrogs was testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Jeroz05/10/2019
I hope I didn’t offend any devs
With poking around
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Was thinking voting would be an excellent use case for restricted assets. Local communities, nations, etc... could kyc their residents
radiodub05/10/2019
Is x16r will remain fpga mineable
Tron05/10/2019
@Jeroz We're hard to offend.
Chill05/10/2019
Is the general dev feeling that the next fork should and will include everything needed for the next 6-9 months (barring something completely unforeseen)?
Jeroz05/10/2019
I know :smile:
Tron05/10/2019
@radiodub Nearly impossible to stop FPGAs and still keep GPUs
Jeroz05/10/2019
About that: voting is another hard fork right? Not too soon?
Tron05/10/2019
FPGAs can be reprogrammed as fast. It is silicon (true ASIC) that we can obsolete with a tiny change.
@Jeroz Messaging, voting, Tags, Restricted Assets would require a hard fork (upgrade).
We could do them each individually, but folks get weary of upgrades, so current plan is to roll them together into one.
MrFanelli™05/10/2019
Good idea
Jeroz05/10/2019
Oh voting too?
MrFanelli™05/10/2019
People will like that
Jeroz05/10/2019
I thought that was coming later
Tron05/10/2019
Voting is the one that isn't being worked on now. Tags and Restricted assets have taken precedence.
Jeroz05/10/2019
I know. But you plan on waiting to fork until voting is also done?
That would have my preference tbh
But I can see an issue with too many things at the same time
Tron05/10/2019
If someone wants to step in, we've had one of our devs sidelined and he was working on BlockBook support so more light wallets can connect to Ravencoin. Mostly test cases needed at this point.
S1LVA | GetRavencoin.org05/10/2019
Thats a pretty large upgrade.. Bigger surface for unknowns
Rikki RATTOE Sr. SEC Impresantor05/10/2019
At what point would RVN community consider moving to ASICs because having a Bitcoin level of security would eventually be needed?
MrFanelli™05/10/2019
Never rikki
Tron05/10/2019
@S1LVA | GetRavencoin.org 100% Lots of testing on testnet and bounties.
[Dev-Happy] Blondfrogs05/10/2019
I am here :smiley:
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor There's nothing inherently wrong with ASICs but it tends to centralize to data centers and less opportunity for anyone to just run their gaming rig overnight and collect RVN.
Welcome Blondfrogs
MrFanelli™05/10/2019
Asics are too expensive. If we want normal people to mine, then we cant be an asic network
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron True but what happens when the chain needs a Bitcoin level of protection?
Tron05/10/2019
More GPUs, more FPGAs
MrFanelli™05/10/2019
Nvidia loves ravencoin :stuck_out_tongue:
Chill05/10/2019
ok, so we are pro FPGAs
𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/10/2019
Build it and they will come

It's all relative. It is cost to attack. If an ASIC isn't available for rent, then only option is rental of non-allocated GPUs
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Chill Eventually everyone will need FPGAs to be profitable on RVN, at that point I don't see why we just don't make the switch to ASICs
Tron05/10/2019
Also, as much as we don't focus on price, the price does matter because it determines the amount of electricity and hardware will be deployed to get the block reward. Price increase means more security, more mining means more security means higher price.
It's a circle.
Chill05/10/2019
someone tell that to the twitter handler
HailKira05/10/2019
you guys adding seedphrase to desktop wallet?
[Dev-Happy] Blondfrogs05/10/2019
@HailKira We will, just is not a high priority right now.
MrFanelli™05/10/2019
Twitter handle wants rvn ded
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I just don't see much difference between ASIC and FPGA and I'd rather have the added nethash an ASIC will provide once GPUs are virtually kicked off the network
kryptoshi05/10/2019
I'm at 11 GB future proof
Tron05/10/2019
That also limits miners to big money, not gaming rigs.
Synicide05/10/2019
@Rikki RATTOE Sr. SEC Impresantor you have to keep in mind the 'added nethash' is all relative
Rikki RATTOE Sr. SEC Impresantor05/10/2019
FPGAs will limit miners to big $$$ too IMO
Tron05/10/2019
@kryptoshi New algo x16r-12G requires 12GB :frowning:
Seal <:cricat:> Clubber05/10/2019
But sperating smaller gb cards would lead to less adoption if we ever become a mainstream coin.
Adpotion of mining that is
Chill05/10/2019
but we are a mainstream coin
Seal <:cricat:> Clubber05/10/2019
Mains stream as in what eth did
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor I agree. Not a perfect solution.
Steelers05/10/2019
Is this a Dev meeting or Algo meeting :smiley:
Seal <:cricat:> Clubber05/10/2019
But if we ever go mem lane. We should aim for 6 or 8gb.
Tron05/10/2019
Open to other questions.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron Probably not the time and the place to have this discussion as we stand currently but IMO we're gonna have this conversation for real eventually
Seal <:cricat:> Clubber05/10/2019
Most cards have 6gb now.
kryptoshi05/10/2019
Why 12 gb ? Such a massive jump
Seal <:cricat:> Clubber05/10/2019
^
Would also like to know
Tron05/10/2019
@kryptoshi I was joking. You said you had 11GB card.

Haha
You got em good
I cant imaghine the face he had when he was 1gb short

Any other questions you have for us?
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs You were testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Chill05/10/2019
a dev might want to contact Crypto Chico for some 'splaining
[Dev-Happy] Blondfrogs05/10/2019
I still haven't contacted the developer that was working on dividends. Was pretty busy with some other stuff. I will contact him this next week, and see where we are at for that.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Chico doesn't do interviews, shame. Tron would be a much needed interview for his community
[Dev-Happy] Blondfrogs05/10/2019
As far as releasing dividends, I can be released at anytime the code is finished and doesn't require any voting or hardfork to occur
kryptoshi05/10/2019
Android asset aware wallet?
Seal <:cricat:> Clubber05/10/2019
Is in beta right
Tron05/10/2019
Testing went well today on Android. Nearing release.
[Dev-Happy] Blondfrogs05/10/2019
as it is a mechanism that is wallet specific
liqdmetal05/10/2019
no protocol level dividends you guys are saying?
[Dev-Happy] Blondfrogs05/10/2019
correct
Tron05/10/2019
DM me if you want to test Android with Asset support. I'll send you the .APK.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
RVN gonna be on tZero wallet? :yum:
liqdmetal05/10/2019
why not? what is the logic on non-protocol dividends
assets + protocol dividends is nirvana
[Dev-Happy] Blondfrogs05/10/2019
dividends is pretty much sending payments to addresses. Right now, you would have to do this manually. The dividends code, will allow this to be done quicker and easier.
No consensus changes are required.
Tron05/10/2019
New Android wallet is BIP44 and original Android wallet is BIP32/BIP39 so the words will not find the funds. You'll need to send them to another wallet, and then send them to new BIP44 derived address.
liqdmetal05/10/2019
we already have payments to addresses
so dividends is not a feature so much as simple wallet script
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs The dividend code changes look risky'er to me than messaging. Would you consider "tags" branch test-ready?
[Dev-Happy] Blondfrogs05/10/2019
Not yet @Hans_Schmidt
Dividends is easier then you would think if coded correctly. I still haven't seen the code from the community developer. Excited to view it though.
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs Sorry- I meant restricted, not dividend
kryptoshi05/10/2019
@Tron on the Android wallet, anyone successfully added their own node and got it to sync faster? Always have issues. I have a supped up node and cannot get it to work with the Android wallet...
[Dev-Happy] Blondfrogs05/10/2019
@Hans_Schmidt Oh, that makes more sense. Yes, they are very risky! That is why we are going to create a new bug bounty program for restricted assets testing.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Once the network does get flooded w FPGAs, should we even consider changing the algo a couple times a year? That would only give bitstream developers added time to hoard their creations for themselves
Kind of like they're already doing with their x16r bitstreams :yum:
kryptoshi05/10/2019
Flooded... lol... like that hardware has mass production scale like gpus...come on dude
MrFanelli™05/10/2019
Bip44 wallet? :smiley:
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@kryptoshi Eventually yes, where there's $$$ to be made, people make things happen
MrFanelli™05/10/2019
So can we trade from that in the new Binance Dex when RVN get listed?
kryptoshi05/10/2019
@Rikki RATTOE Sr. SEC Impresantor Yes Soon TM lol. :soontm:
Tron05/10/2019
@kryptoshi There are some things we can do to speed it up. For a new wallet, it shouldn't need to sync. For recovered wallet, it needs to sync from beginning of BIP44 wallet support on iOS so words can be moved between the two.
Other options include grabbing the first derived address and looking it up on an explorer to see when it was first used and sync from there.
Another option is to add an optional number with the 12 words so it knows when to start syncing.
There isn't a good reason on an SPV wallet to sync before the seed was created.
kryptoshi05/10/2019
Cool. Glad you are looking at speedup options.. :right_facing_fist: :left_facing_fist:
[Dev-Happy] Blondfrogs05/10/2019
@MrFanelli™ If the binance dex support RVN deposits. I am sure you would be able to send from it
MrFanelli™05/10/2019
Has binance reached out for any info or anything?
I seen that we ranked in some voting competition they had on twitter
for an ama
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I believe we'll need to create a fund of approximately $300,000 in order to get a BNB-RVN asset created and listed on the Binance FDEX
[Dev-Happy] Blondfrogs05/10/2019
In order to work with binance we need Ravencoin integrated into Blockbook.
Tron05/10/2019
@MrFanelli™ I've reached back out to Binance on the AMA.
MrFanelli™05/10/2019
Awesome :smile:
kryptoshi05/10/2019
@Tron you are a natural on the interviews... cool as a cucumber. :sunglasses:
Tron05/10/2019
Thanks @kryptoshi
[Dev-Happy] Blondfrogs05/10/2019
Cool. We are done for today.
Please don't ask us any more questions :smiley:

MinedBlock - Mining As A Service.

MinedBlock - Mining As A Service.

https://preview.redd.it/z9qndkht4vb31.png?width=788&format=png&auto=webp&s=25d1b844389dc51a159ea5f88f126e8febec6e75
MinedBlock offers the opportunity for investors to take advantage of using the resources from a large-scale mining operation, mining multiple crypto assets without the need to buy, configure and maintain expensive mining equipment. Our unique approach to this activity gives you a fully secured and compliant token granting you a share of ownership of the holding company behind the service and not just a ‘random utility token’.
MinedBlock is a Fintech Crypto Mining & Infrastructure Service Provider specialising in transaction processing, or ‘mining’, for crypto currency transactions. The ‘Parent’ company MinedBlock Limited will own all of the assets, infrastructure and operation while the ‘Subsidiary’ company will own the ‘Service’. The reason behind this model is to tokenise equity in the subsidiary while retaining private ownership of all the assets in the parent company. 25% of revenues will be retained by the parent company to be used for ongoing expansion and operational costs. Miners, collectively, provide the backbone infrastructure network for cryptocurrency blockchains, the blockchain provides a single, distributed ledger across multiple ‘nodes’ (specialist mining hardware) which perform the activity of ‘mining’ transactions. The blockchain is a distributed, un-editable database which stores transaction information, crypto wallet* balances and details of minted (newly created) coins. Mining validates those transactions, processes payments and updates them to the distributed ledger in a new block. Each block contains a reward of new cryptocurrency which is awarded to the miner (minted) along with the transaction fees for the processed payments in that block. For example, a miner who mines a new bitcoin block would earn 12.5 Bitcoins plus 0.25** Bitcoin in transaction fees. In the beginning, Bitcoin was a person-to-person (P2P) method of transferring ‘value’ and was mined using generic laptop and desktop computers. Over the last decade; the popularity, use case and validity of Bitcoin and other cryptocurrencies has grown beyond the ability of most people to stay involved with mining. Whilst the exchange/brokerage side of the crypto ‘industry’ has evolved and firmly established leaders such as Coinbase or Binance, there isn’t really a comparable entity in the mining arena. Bitmain is probably the biggest but they are primarily a hardware manufacturer and don’t focus solely on transaction processing. Their remit is limited to the range of assets that they can mine using the hardware they manufacture and own. During the 2018 ‘crypto bull’ market, many mining companies appeared but failed to properly prepare for the event of a downturn and in the ‘bear’ market in the latter half of 2018 have disappeared. At the point in December 2017 where Bitcoin price peaked at $20,000 the blockchain couldn’t cope with the sheer volume of transactions and the fees were astronomical. Transactions were taking over 2 hours and costing up to $40 in fees. The total crypto market value is still relatively low at the moment, so the opportunity is ripe for MinedBlock to establish ourselves as a company bringing a corporate approach to the crypto mining industry. By establishing ourselves while the crypto market value is lower, we are protecting ourselves and our investors against any potential future downturns.
https://preview.redd.it/kehz0rfw4vb31.png?width=570&format=png&auto=webp&s=79bea7844ee990f4ba24df4b60fbcf2aa2750a44

Advantages

+ Scalable MinedBlock’s service is endlessly scalable, in order to grow the service we simply would install and configure more mining equipment. There isn’t any technical limitation to how big it could get. MinedBlock has the ability to quickly and easily expand into multiple revenue streams including, but not limited to, expansion of the range of mined crypto assets and the ability to host private mining services. + Agile Initially, 40% of our infrastructure will be dedicated to cryptocurrency other than Bitcoin, this will enable the service to flex and switch between the asset being mined allowing us to always target the assets with the best returns based on market demand. The 60% initial allocation to Bitcoin can also be adjusted based on market prices and returns. + Sustainable MinedBlock is focussed on hosting our infrastructure in areas that can provide 100% renewable energy. + Market Immunity Phase 2 of the project, which is out of scope for this round of funding, will be to build our own renewable energy sources to offset electricity costs, the primary ongoing cost factor, thus enabling continuous revenue production regardless of crypto market prices. + Projected Revenue MinedBlock will produce revenue through mining a strategically selected range of cryptocurrencies. Another way to ‘mine’ crypto is to buy and hold a minimum number of a coin in a wallet which entitles the holder to a share of transaction fees (similar to earning interest on a savings account). This is known as a ‘Proof of Stake’ method of mining. Publishing a wallet for Proof of Stake mining is called hosting a masternode. There are always new technological advances in the mining industry including strategies and technologies which we are prepared to adopt and add to our service. + Unique Selling Point (USP) Our USP compared to the competition is that we plan to make ourselves fully immune from the market, prioritise our investors (over ourselves) and be 100% transparent in everything we say and do. Most other mining firms have focused on just ‘out of the box’ mining and not considered any form of cost reduction or alternative revenue generation such as masternodes, and this has left them unprofitable and unable to continue. Our aims go far beyond ‘just being another mining company’ we intend to dominate the space as quickly as possible. At this stage, there isn’t really any meaningful competitor in the marketplace as the mining industry is still in its infancy.
