Bitcoin Cash is preparing to forge for blocks at 32 MB, but especially for the return of op-codes
In recent weeks, the Bitcoin Cash community has been debating the use of new "op-codes" on the same channel. It could allow the implementation of arbitrary data in the manner of Ethereum , thus making it possible to execute smart-contracts, and thus (among other things) the management of tokens. The reinstatement of some op-codes deactivated during the history of the Bitcoin chain and certain scripting capabilities has attracted the enthusiasm of BCH supporters and, after the hard-fork planned for next May, the community will see new op-code features.
Tuesday, May 15, Bitcoin Cash will "forge" to allow an increase in the maximum size of the blocks that will grow to 32 MB. If this information has been one of the main specialized media, it goes hand in hand with adding or reactivating "multiple bitcoin script operation codes (op-codes)". Op-codes - abbreviation for "operation codes" - are essentially machine-language instructions that allow the execution of a specific task.
The re-emergence of opcode deployment has been under discussion for some time, but was recently mentioned when Andrew Stone of Bitcoin Unlimited announced the 'Op-Group' meeting on Github . Amaury Sechet of Bitcoin ABC, Dan Connolly of bitcoin.j.cash, Steve Shadders of Nchain and other programmers participated in this meeting on Telegram.
"In order to support non-trivial cases of cash use for the Bitcoin Cash Block Chain, a number of ecosystem participants would like some of the original Bitcoin op-codes to be reactivated for use in contracts. smart ", explains the summary of the meeting last February.
Attention danger
According to the meeting, developers will reintroduce nine operation codes that were once available in older bitcoin implementations. Some of these op-codes were removed because the fear of bugs was present. For example, in an earlier version of the Bitcoin codebase, op-code 'OP_LSHIFT' could crash any bitcoin node if it was running. The reinstatement of these codes has therefore been accompanied by some controversy within the Bitcoin Cash community.But finally, the current rigidity of the Bitcoin protocol from which Bitcoin Cash is derived, is seen as too important to allow its growth and diversification. The integration of tokens like Ethereum's ERC-20 tokens, or intelligent contracts was considered more important than the risk incurred in the event of bad implementation of op_codes.
Currently, the only way to write arbitrary data into the Bitcoin blockchain is to hijack the OP_RETURN function , which is usually used to mark transactions as invalid. In addition to being extremely decried , this method can store up to 83 bytes, a derisory size. It is this op-code that was used to store child porn links .
