Ethereum developers have submitted a draft proposal to replace the network’s validator deposit contract, marking the first concrete step toward protecting the blockchain’s staking layer from quantum computing attacks.
The draft Ethereum Improvement Proposal, filed to the EIP repository on Monday, targets a fundamental limitation baked into the existing deposit contract: it hardcodes the dimensions of the BLS12-381 signature scheme, fixing public keys at 48 bytes and signature metadata at 96 bytes. Post-quantum cryptographic schemes require far more space, and the current contract cannot accommodate them.
