What the specification covers

AbstractMotivationSpecificationRationaleBackwards CompatibilityReference ImplementationSecurity ConsiderationsAttacks and mitigationsAttack: Relay attempts to censor a transaction by not signing it, or otherwise ignoring a user request.Attack: Relay attempts to censor a transaction by signing it, returning it to the sender, but never putting it on the blockchain.Attack: Relay attempts to censor a transaction by signing it, but publishing a different transaction with the same nonce.Attack: Relay attempts to censor a transaction by signing it, but using a nonce higher than it's current nonce.Attack: Dapp attempts to burn relays funds by implementing an inconsistent acceptRelayedCall() and using multiple sender addresses to generate expensive transactions, thus performing a DoS attack on relays and reducing their profitability.Attack: User attempts to rob dapps by registering its own relay and sending expensive transactions to dapps.Attack: Attacker attempts to reduce network availability by registering many unreliable relays.Attack: Attacker attempts to replay a relayed transaction.Attack: User does not execute the raw transaction received from the Relayer, therefore blocking the execution of all further transactions signed by this relayerCopyright

This proposal declares no Solidity interface, so there is nothing to compute. It may be a core protocol change, a meta proposal, or written in prose only.
