This template will provide you with the basics to stay safe during a coin-split, and make sure you make it to the “ other side ” with both your BTC and BTU intact. Author ’ mho note : If you want to play the BTC/BTU markets vitamin a soon as possible and you are fine with taking risks, and/or you truly know what you are doing, this article is probably not for you. ( possibly try this Electrum article rather. ) If you largely equitable want to make certain not to lose your BTC or BTU, read on …
Before the Coin-Split (That’s Now)
First of all, be aware that a coin-split is a bad position. There is a real opportunity a sort of cyber-battle will break out between the two camps, possibly even escalating to the point where bitcoin ’ second rally rate ( s ) drops precipitously, possibly to zero. Make absolutely certain you are not holding more value in bitcoin than what you are uncoerced to lose. If you do decide to hold on to your bitcoins, the one most crucial part of advice is this : control your own individual keys. If you are storing your bitcoins on an rally, in a custodial wallet like Coinbase, Circle or Xapo, or on any other service that holds your individual keys for you, you may or may not finally receive coins on both ends of the chain. several exchanges have so far suggested you may but have made no guarantees. And at least one exchange, GDAX, has explicitly indicated you may not. If you ’ re using any of these kinds of services to store your bitcoins, you need to create your own wallet. Send your bitcoins to this raw wallet ; this wallet now holds your private keys. What kind of wallet you want to use is up to you. That said, here are some basic solutions : If you don ’ deoxythymidine monophosphate caution about transacting with either BTC or BTU anytime soon, and actually just want to keep both as a long-run investment, printing your individual keys on a paper wallet is one choice. This option, however, is only actually secure if you follow rigorous security precautions, which you can find here. Another option is to get a hardware wallet. Any of the hardware wallets listed on bitcoin.org will keep your individual keys secure. One hardware wallet supplier in particular, Trezor, has explicitly acknowledged that users will have access to their coins on both ends of the chain if a coin-split happen. regular wallets are about adenine procure as your computer ( or phone ) is. Since most computers and phones are not all that secure, these are not ideal for large amounts. With that in heed, all mobile wallets and desktop wallets listed on bitcoin.org will store your private keys for you. additionally, a full node like Bitcoin Core or Bitcoin Knots gives you a little supernumerary security system during a coin-split, as you ’ ll watch below. In any case : Make certain you make backups of your keys ! Most wallets require you to do this when install ; don ’ metric ton decamp this footprint .
During the Coin-Split
The first matter to note is that Bitcoin Unlimited has not set a “ pin date ” to fork. This means that theoretically, a fork could happen at any time. realistically, however, it will depend on miner coordination, and it will credibly be obvious to even casual Bitcoin observers when a pitchfork is close to happening. If Bitcoin Unlimited does crotch, things could get messy for anywhere between a couple of hours to a couple of days, or longer. unfortunately, Bitcoin Unlimited presently does not include “ replay protection. ” This means that post-fork, transactions on both sides of the branch will look identical. If a transaction is picked up by both networks — for example, because the liquidator of a transaction re-transmits the transaction on the other network — that transaction may be valid on both chains. This is called a “ play back attack. ” As such, spending coins on one end of the chain could make you incidentally spend the equivalent coin on the other side of the chain. alternatively of paying person only BTC, you may unintentionally send BTU as well — or vice versa. This is how the BTCs and BTUs are “ stick together. ”
The best manner to prevent replay attacks is childlike : do not send any transactions. not until it is clearer to everyone what the post-fork situation looks like. If you use Bitcoin Core or Bitcoin Knots as a wallet and you want to accept BTC, that should hush be fine. ( person who didn ’ thyroxine read this article may by chance send you the equivalent in BTU, though. If this happens, you should probably return the funds later on. ) Bitcoin Unlimited, on the other bridge player, does not include “ wipeout protection. ” If the amount of mining power on the BTC chain ever overtakes the BTU chain, the entire BTU chain will be discarded ( unless users on the BTU chain coordinate fast adequate to prevent this in unconventional ways ). Unless and until it is absolutely clear that Bitcoin Unlimited emerges as a definitive winner everlastingly, accepting any BTU is very hazardous, and you credibly shouldn ’ metric ton do it at all .
After the Coin-Split
If both chains survive, and you control your private keys, you will have coins on both sides of the fork. But as mentioned, it will be crafty to spend coins on one chain without incidentally spending the equivalent on the early side. fortunately, there are ways to avoid these replay attacks. The most straightforward solution requires brand-new coins, mined after the rip. These new coins are the only coins that do not exist on both chains and can not, therefore, be spent on both. Combining these modern coins with old coins efficaciously splits the BTC from BTU. This coin-splitting can, and probably will, be a bit complex. But some exchanges will likely set up coin-splitting services and take manage of most of the complexity behind the screens. You ’ d equitable need to send your bitcoins to an rally, and the switch over will credit your account with BTC and BTU. ( They should evening replay the transaction for you, to make certain they indeed receive both your coins and can split them for you. ) If you want, you can nowadays besides sell your BTU for BTC ( or fiat currency ), or the early way beat. There may besides be early solutions to split your coins in the event of a coin-split, possibly even trustless solutions. But that remains to be seen. After the split, there will credibly be wallets for both coins soon enough. Of path, you may need to upgrade your existing wallet or download a newly wallet if and when this happens. This besides remains to be seen. ( Do not accept any transactions on your wallet before this is clear. ) far specifics on what to do after a coin-split will be announced on Bitcoin Magazine ( and most probably on bitcoin.org and early sources of information ) if and when a coin-split occur and we have a better understanding of the post-fork situation. Oh, and when you, years from now, want to use the funds stored on your paper wallet, don ’ triiodothyronine forget you now own both BTC and BTU ! ( Wallets like Electrum and Blockchain allow you to upload the private keys, and you ’ ll credibly need to go through the like separate ceremony. ) If entirely one chain survives, operations should continue at some point. however, it ’ s not precisely clear what this post-fork landscape will look like. possibly you ’ ll have to upgrade your wallet. This will besides be announced on Bitcoin Magazine if and when it comes to it. If neither chain survives, the Bitcoin experiment has failed, and your private keys will probably be despicable .
So, to Recap …
1. Control your private keys. 2. To be on the safe side, avoid any transactions soon after the split. ( If you must accept BTC, practice Bitcoin Core or Bitcoin Knots as a wallet. )
3. As the dust settles, split your coins. ( How, precisely, will depend on Bitcoin ’ s post-fork landscape. ) This article will be updated as the newsworthiness develops .
