Enforceable Human-Readable Transactions: how to solve Bybit-like hacks

Each application would embed an enforceable, human-readable description in the messages users sign, and its smart contract would reject any signature where that description does not match the transaction data. The approach responds to the $1.5 billion Ethereum theft, in which spoofed front-ends tricked signers while the wallet displayed the data correctly. The description is recomputed from the input data on-chain, so it needs no extra data availability, though each transaction gains computational overhead and users must sign twice, a problem the upcoming Pectra fork may help address. The text says the technique suits Cartesi application-specific rollups, which offer dedicated blockspace.
