[BIP Proposal] Limit ScriptPubkey Size >= 520 Bytes Consensus.

Oct 3 - Oct 3, 2025

  • The discussion revolves around a Bitcoin Improvement Proposal (BIP) that suggests setting a minimum size limit for ScriptPubkey at 520 bytes.

This proposal is highlighted in the exchanges between members of the Bitcoin development community. One prominent argument against this proposal is the concern that users might circumvent the size restriction by utilizing more outputs. However, this worry is mitigated by the fact that the witness size isn't subjected to similar limitations, which can potentially avoid complications related to Denial of Service (DOS) attacks that can occur with certain configurations, such as those involving the GNU Compiler Collection (GCC).

Furthermore, the correspondence underlines a positive reception towards the idea, suggesting that its implementation could streamline certain technical processes and enhance the overall robustness of the system against specific types of vulnerabilities. The interaction concludes with an endorsement of moving forward with the proposal, indicating a collective interest in pursuing measures that refine and secure transactional mechanisms within the Bitcoin network.
