Module farcaster_core::protocol

Protocol execution and messages exchanged between peers. Execution steps of a swap are carried by Alice and Bob structures. Each contain the list of methods needed to proceed a swap.

Modules

message

Protocol messages exchanged between swap daemons at each step of the swap protocol. These messages are untrusted and must be validated uppon reception by each swap participant.

Structs

Alice

Alice, a SwapRole, starts with accordant blockchain assets and exchange them for arbitrating blockchain assets.

ArbitratingParameters

Container for the set of parameters needed to build or verify some parameters on the CoreArbitratingTransactions.

Bob

Functions

commit_to_vec

Transform a vector of tagged elements K into a vector of tagged commitments. CanonicalBytes are used for computing the commitment of each elements.

verify_vec_of_commitments

Verifies a vector of tagged commitments against a vector of revealed tagged elements. Fails if a tag is not found in the commitments or doesn’t match the commitment. CanonicalBytes are used for computing the commitment of each elements.
