Note from the author: I believe BIP110 to be both harmful and useless, and that it will fail. (See scenario 1). Nevertheless, I wrote this article with as much accuracy as I possibly could. While I entertained different possibilities, I hoped it would provide some clarification on the soft fork experiment.
It is important to note that the word “you” means “you”. OP_RETURN debate Bitcoin Knots have been introduced as a result of the rapid growth in Bitcoin. BIP110: a protocol modification that limits temporarily the size of OP_RETURNs, and also intends to limit other data types on Bitcoin’s blockchain.
BIP110 is not a consensus. Not everyone believes that there’s an issue that needs to be solved, or that BIP110 will solve it. It also restricts Bitcoin, which could have harmful effects. Most obviously, Bitcoin Core — still by far the most-used Bitcoin implementation — has not adopted BIP110, while only some 1-2% of hash power Recently, there has been a growing support for the bill.
Nevertheless, BIP110-nodes like Bitcoin Knots will soon — starting from block 961,632, to be mined on or around August 8 — reject blocks that don’t signal support for the upgrade.
The three most likely scenarios are listed below.
Scenario 1: (almost) no miners signal
The current signalling of miners is a good indicator.
Blocks will continue to be mined and processed as normal for anyone using Bitcoin Core, or any other non-BIP110 enforcer nodes or wallets. This is the vast majority of Bitcoin users. If you’re not following these events, on Twitter or anywhere else, it’s possible that no one will be aware of anything abnormal happening. In a practical way there won’t even be any. BIP110 doesn’t affect them.
This isn’t true, though, for users of Bitcoin Knots (or other BIP110 nodes) or BIP110. They will not see new blocks (or maybe a couple per week) and transactions incoming or outgoing won’t be confirmed (or extremely slow). These nodes will stall, and eventually become useless.
BIP110 advocates will then have to make a decision between giving up and switching back to BIP110-compatible software, or forking the protocol to another algorithm for proof-ofwork mining.
A hard fork could allow mining using GPUs, allowing more people to mine blocks and generate blockchains with BIP110 enforced. This would mean, however, that the BIP110/hard-fork nodes will permanently separate from the Bitcoin ecosystem in order to create a brand new cryptocurrency. More on this is below.
Scenario 2: (almost) all miners signal
This is what several BIP110 supporters predict.
In this case, as soon as the mandatory window for signaling opens, all of the miners suddenly start signaling BIP110. At least, the majority of miner will reject all non-signaling and signal blocks so that BIP110 is included in every block.
All Bitcoin nodes, both Knots and Core, will remain compatible if this occurs. The signals found in blocks also indicate that the miners intend to enforce the BIP110 regulations two more weeks down the road. By early September, BIP110 violations should no longer be included in the blocks.
The BIP110 upgrade is a success in this scenario. Even though only a minority of users, developers and miner pushed the issue, it was adopted by the whole network.
…However even in this scenario there is an important caveat.
The blockchain signaling mechanism is useful for soft-fork deployment but does not ensure that new rules are enforced. The upgrade can be supported by miners without using BIP110. They could do this, for instance, to make sure their blocks won’t get rejected by Bitcoin Knots during the signaling period.
Bitcoin’s rules will ultimately be enforced by the economic nodes. However, nothing suggests that they are likely to enforce BIP110. even if Signals are included in all blocks. So, if BIP110 violating transactions were to be accepted in the future by most miner nodes regardless of their BIP110 violation, economic nodes that accept them would do so, but BIP110 proponents would refuse. This would cause the blockchain to split up between nodes who enforce BIP110, and those who don’t.
Scenario 3. A large minority of coal miners signals
The chain would be immediately broken in this scenario.
The current support of BIP110 is only about two percent, which may not be enough to make a difference (see Scenario 1). Let’s say this increases by about a tenfold. We also have to imagine that this sizable minority itself rejects any non-signaling blocks— else it would still be indistinguishable from scenario 1 where BIP110 nodes stall (since they require ALL blocks to include a signal).
They would then start building their own blockchain, which only contains signaling blocks. Blocks on this minority chain would confirm significantly slower than usual — maybe just one or two per hour — but BIP110 nodes remain reasonably usable. The mining difficulty will adjust after a couple of months, and blocks should be found at (closer-to) six per hour. The BIP110 regulations would be implemented a few weeks after that.
Bitcoin Core, and any other non-BIP110 enforcer node would continue to operate as normal. Their blocks will confirm a little bit slower for a while — maybe about four or five per hour — but after a couple weeks mining difficulty adjusts here too, to also bring this back to six per hour on average. BIP110 will never be implemented on this chain.
A BIP110 and an original blockchain would be able to exist forever as separate cryptocurrencies.
This scenario is not without its own caveat. If the BIP110 chain were to overtake the original chain in length later on (due to miners moving to the BIP110 chain), all nodes — Core and Knots alike — would accept the BIP110 chain as the only chain. This original chain will be either discarded in this instance, or Wiped out.
The one-sidedness of this article Delete risk BIP110’s proponents believe that miners should signal ahead of time to avoid a possible split. The argument is that the miners would not like to mine a blockchain which can be deleted later, because that means losing their block rewards.
However, users or miners can still prevent the original BIP110 chains from getting wiped. They could manually invalidate blocks while the BIP110 is still a minority chain. The nodes of their network would then refuse to switch over. even if It can become longer in the future at any time, which makes the separation permanent.
What happens exactly if the link permanently breaks?
The Bitcoin blockchain will split permanently if and when it does. This would essentially create a new currency. Forkcoin. Everyone who owned BTC when the split occurred received the same amount of coins in the new blockchain. This is similar to what happened last year with Bitcoin Cash and Bitcoin.
In reality, however, these scenarios are not as simple. If BIP110 causes a split in the chain under one of the above scenarios there may be complications.
One of the most likely disagreements will be over which chain side you’re on. “Bitcoin” (“BTC”It is important to know which forkcoin you are on (which side). The blockchain that has the original rules is likely to be the one most people consider. “Bitcoin”The blockchain that has the BIP110 regulations will have a different name; it’ll be called “BIP110”. “BIP110 coin” Now, let’s not worry about it.
Bitcoin Knots is the only software that can access BIP110. These new coins will not appear on Bitcoin Core or in most wallets.
BIP110 is not available at this time. Replay protection. The transactions of one chain may be duplicated (“replayed”The user can send the equivalent BIP110 coin to an identical address on the BIP110 chain, or vice versa. Instead of just sending BTC, users could unknowingly also send the equivalent BIP110 coin to an identical address on the BIP110 chain— or vice versa.
The value of the forkcoins is difficult to predict at this time. This lack of interest is a result of the fact that BIP110 coins are not being purchased via fork future contracts It seems that there is not much of an interest in buying them either after the split. You can still be certain that you will receive BIP110 coins, if they exist. But it is best to keep your BTC in your own custody (have your private keys) and to wait until all the confusion has passed before sending any transactions.
