ckb-tx-message-all-test-vector-utils

A suit of utilities & sample contracts leveraging the new CKB_TX_MESSAGE_ALL spec. Several notable components include:

  • crates/ckb-tx-message-all-utils: A Rust crate that performs CKB_TX_MESSAGE_ALL calculation. Both on-chain and off-chain environments are supported.
  • crates/native-test-vector-generator: A native test vector generator for working with CKB_TX_MESSAGE_ALL spec.
  • contracts/rust-assert-ckb-tx-message-all: A simple Rust-based CKB script that validates the lock field from the first witness(in WitnessArgs structure) of current script group, contains the CKB_TX_MESSAGE_ALL hash for current transaction & script group, using CKB flavored blake2b hash as the hasher. Notice this is not a secure lock script, a proper one shall validate a signature calculated on the CKB_TX_MESSAGE_ALL hash, not comparing the hash value directly.

This project was bootstrapped with ckb-script-templates.
