Account model (Ethereum / Solana)
Global accounts with balances/nonces (and program data) rather than Bitcoin-style UTXOs—changes hygiene stories, not the need for quantum-safe signatures.
Definition
Account-based chains track state in addresses/accounts. Authorization is typically “signature from an authority key,” not “reveal pubkey only when spending a specific UTXO.”
Quantum planning still centers on those authority keys and operational custody—plus chain-specific admin/upgrade powers.
