Ethereum Community: EIP Proposal for Post-Quantum Deposit Contract Released

The Ethereum community has released an EIP proposal for a deposit contract supporting post-quantum computing. The proposal introduces a new contract supporting variable-length public keys and credential metadata, along with explicit scheme identifiers, with scheme 0 reserved for current BLS deposits. The new contract no longer relies on the Merkle tree structure of the old deposit contract; instead, it passes deposit information to the consensus layer via execution-layer requests derived from EIP-7685 logs. The contract features an irreversible mode controlled by protocol system calls: deposits are initially disabled, BLS deposits are enabled at a specified timestamp, and permanently disabled at a later timestamp with no possibility of re-enabling. During the migration period, execution clients are required to merge deposit requests from both the old and new contracts.
