๐จ Bitcoin Core 30.0 has arrived: OP_RETURN now supports up to 4MB. Revolution or threat? ๐ฃ
The new version of Bitcoin Core has been released and brought the largest expansion of OP_RETURN in history.
๐ From 80 bytes โ up to 4 MB per transaction ๐ฑ
๐ Multiple OP_RETURN fields are now allowed
๐ 577 improvements in the code (faster IBD, CMake, Stratum v2 and more)
๐ But why does this matter?
OP_RETURN allows the insertion of arbitrary data into the Bitcoin blockchain. Now, with much more space available, the network can be used for things beyond financial transactions โ such as NFTs, messages, files, and even ordinals.
๐ฏ For some, it is the future of programmability in Bitcoin.
โ ๏ธ For others, it is congestion disguised as โinnovation.โ
๐ง Other important changes:
๐ ๏ธ Limit of 2,500 signature operations per tx (protection against DoS)
๐ธ Minimum fees adjusted (block minting fee now at 0.001 sat/vB)
โ๏ธ IBD 20% faster + wallet migrated 100% to descriptor wallets
๐ง Question for the community:
Is this change a step towards a more versatile Bitcoin?
Or are we playing with fire and compromising the original mission of
$BTC ?
