BIP-110 proposal controversy heats up: Adam Back warns that Bitcoin's upgrade capability may be suppressed

The discussion surrounding Bitcoin Improvement Proposal BIP-110 continues to heat up. Bitcoin pioneer and Blockstream co-founder Adam Back retweeted to remind the community that Bitcoin's upgrade capability may be suppressed. This proposal, although described as a temporary soft fork to clean up "garbage data" on-chain to curb the on-chain data inflation brought by protocols like Ordinals, may hinder Bitcoin's future upgrade capabilities because it disables the OP_SUCCESS opcode in Tapscript, which is seen as an important reserved mechanism for future soft fork upgrades of Bitcoin.

Additionally, BIP-110 will limit the Taproot control block size to 257 bytes, which may affect the development of potential Layer 2 technologies like BitVM that rely on extensive script execution. Although BIP-110 is positioned as a "temporary measure," Bitcoin soft fork upgrades typically require years of coordination, and restricting upgrade interfaces during this period may have long-term impacts.
