pub struct PrecompileTranscript { /* private fields */ }Expand description
Precompile transcript implemented as a linear hash tree over Poseidon2.
§Structure
The transcript holds a single 4-element Word — the rolling state. After each record call,
the state is itself a complete digest of every commitment absorbed so far.
§Operation
For each commitment, the transcript first computes the per-call statement
STMNT = Poseidon2::merge(COMM, TAG) (see PrecompileCommitment::statement), then folds the
statement into the rolling state via the 2-to-1 hash
state' = Poseidon2::merge(state, STMNT). The state is exposed directly as the transcript
digest — no finalization step is required.
Implementations§
Source§impl PrecompileTranscript
impl PrecompileTranscript
Sourcepub fn new() -> PrecompileTranscript
pub fn new() -> PrecompileTranscript
Creates a new transcript with the zero word as initial state.
Sourcepub fn from_state(state: Word) -> PrecompileTranscript
pub fn from_state(state: Word) -> PrecompileTranscript
Creates a transcript from an existing state (for VM operations like log_precompile).
Sourcepub fn state(&self) -> Word
pub fn state(&self) -> Word
Returns the current transcript state (also the rolling digest of all recorded commitments).
Sourcepub fn record(&mut self, commitment: PrecompileCommitment)
pub fn record(&mut self, commitment: PrecompileCommitment)
Records a precompile commitment into the transcript, updating the state.
Folds the per-call statement STMNT = Poseidon2::merge(COMM, TAG) into the rolling state
via state' = Poseidon2::merge(state, STMNT).
