Ethereum developers are reviewing an unmerged draft to redesign the staking deposit system for future quantum-resistant validator credentials while eventually preventing new deposits using today’s BLS format. Pull request #12235 was opened on Aug. 24 and remained a Draft as of Aug. 26; its working file uses placeholder number 9999, while an EIPs editor suggested 8394. The proposal has not been published or accepted as EIP-8394. It would add a scheme identifier and variable-length public-key and credential fields capped at 8,192 bytes, with the execution layer carrying deposit data and the consensus layer deciding whether credentials are valid and can create or update validators. The draft defines forward-only modes for disabled, BLS enabled and BLS retired, with deposits entering the pending queue before retirement remaining eligible for normal processing. Separate protocol upgrades would still be required to define new cryptography, validator-state rules and any replacement of validator signatures. The work supports Ethereum’s longer-term quantum-resistance planning, including leanXMSS, leanVM and an approximately 2029 planning target.
