Staking Ethereum could soon look entirely different under a new deposit proposal

Ethereum developers have opened an early proposal to make the staking deposit system flexible enough to accept future quantum-resistant validator keys, and it would also give a later network upgrade a one-way switch to stop new deposits using today’s BLS format.

The change would affect how new validators enter Ethereum, creating an entry path for future credential formats. Yet, those formats and the rules for verifying them still have to be designed and adopted separately.

Pull request #12235 was opened Aug. 24 and remained an unmerged Draft as of Aug. 26, with its working file still using the placeholder number 9999. An Ethereum EIPs editor suggested assigning 8394, but the proposal has not been published or accepted as EIP-8394.

How the deposit switch would work

Ethereum’s staking deposit contract is the entry point that receives a prospective validator’s funds and credential data. The current path expects public keys and signatures in fixed BLS12-381 formats.

The draft specification instead adds a scheme identifier and variable-length fields for the public key and credential metadata, each capped at 8,192 bytes.
