Final Comment Period: CAP-0076

[Justin]

Hello Stellar Devs,

CAP-0076: P23 State Archival bug remediation is now in final comment period pending acceptance.  You can read the proposal here:
https://github.com/stellar/stellar-protocol/blob/master/core/cap-0076.md

This Core Advancement Proposal addresses a bug in Stellar's state archival feature that was discovered October 9, and quarantined through validator action October 10. The bug, found in Whisk (Protocol 23) which the network upgraded to on September 3, 2025, resulted in outdated entries being archived and then restored incorrectly, producing state that did not match the canonical onchain history.

In addition to reviewing CAP, you can read more about the immediate response to the discovery, the assessment of the bug, the proposed fix, and the timeline of action in this blog post:
https://stellar.org/blog/developers/addressing-state-archival-inconsistencies-protocol-upgrade-vote-next-week

CAP-0076 will remain in final comment period until 1700 UTC, October 22, which is when validators will vote on whether to accept the Protocol 24 upgrade that implements the CAP.  If you have questions or comments, please raise them here before then.

Thank you for your attention!
