Bitcoin core developers are engaging in intense discussions about removing the OP_Return data storage limit. Peter Todd's PR 32359 proposal suggests abolishing the current 83-byte data carrier output limit, a proposal that has received theoretical support from Chaincode Labs developer Antoine Poinsot. Developers have pointed out that the existing limit has proven ineffective, as users still store non-financial data through various means such as Taproot unspendable outputs and miner private mempools (e.g., MARA Slipstream). Supporters argue that the current limit is ineffective and hinders legitimate use, while opponents, represented by Luke Dashjr, describe the proposal as "completely insane," emphasizing that vulnerabilities should be fixed rather than tolerating "spam data attacks." Developers continue to comment via mailing lists and GitHub; some express support with "concept ACK," though comprehensive technical testing has not yet been conducted, while others express opposition with "concept NACK."

PANews reported on April 29 that according to Protos, Bitcoin core developers are engaged in a heated debate on the removal of OP_Return data storage restrictions. Peter Todd's PR 32359 proposal proposes to abolish the current 83-byte data carrier output limit, which has received theoretical support from Chaincode Labs developer Antoine Poinsot. Developers pointed out that the existing restrictions have been proven to be ineffective - users continue to store non-financial data through various methods such as Taproot unspendable outputs and miners' private memory pools (such as MARA Slipstream).
 Supporters believe that the current restrictions are ineffective and hinder legitimate use cases; Luke Dashjr, a representative of the opposition, denounced the proposal as "completely crazy" and emphasized that vulnerabilities should be fixed rather than condoning "junk data attacks." Developers are posting new comments every hour through mailing list threads and GitHub. Some people expressed support with a simple "concept ACK", but no comprehensive technical testing has been carried out, while others issued a "concept NACK" to express opposition.
