Tezos Protocol Implementation - Protocol Signature Instance

This module is the entrypoint to the protocol for shells and other embedders. This signature is an instance of the Updater.PROTOCOL signature from the Protocol Environment.

Each Protocol depends on a version of the Protocol Environment. For the currently developed protocol, this is normally the latest version. You can see the full list of versions here.

For details on how Protocol and Environment interact, see this overview.

check_manager_signature validation_state op raw_operation The function starts by retrieving the public key hash pkh of the manager operation. In case the operation is batched, the function also checks that the sources are all the same. Once the pkh is retrieved, the function looks for its associated public key. For that, the manager operation is inspected to check if it contains a public key revelation. If not, the public key is searched in the context.

  • returns

    Error Invalid_signature if the signature check fails

  • returns

    Error Unrevealed_manager_key if the manager has not yet been revealed

  • returns

    Error Failure "get_manager_key" if the key is not found in the context

  • returns

    Error Inconsistent_sources if the operations in a batch are not from the same manager

precheck_manager validation_state op returns () if the manager operation op is solveable, returns an error otherwise. An operation is solveable if it is well-formed and can pay the fees to be included in a block with either a success or a failure status. This function uses Apply.precheck_manager_contents_list but discard the context and balance update
