ERC-8403: an account as one hash

ethresear.ch: ERC-8403, an account as one hash, and post-quantum keys

11:24 (AnkushinDaniil). The account stores one 32-byte root. Each authority (a signing key, or a rule such as a spend limit or an unlock time) is a leaf, `leaf = keccak256(authority_id || predicate)`. A transaction carries a membership proof that the leaf is under the account's root, and a witness that the leaf's holder approved the transaction. The post then asks what the account looks like with post-quantum keys on top of EIP-8288.
