Traits

CommitEncode

Prepares the data to the consensus commit procedure by first running necessary conceal and merklization procedures, and them performing strict encoding for the resulted data.

CommitId

High-level API used in client-side validation for producing a single commitment to the data, which includes running all necessary procedures like concealment with crate::commit_verify::Conceal, merklization, strict encoding, wrapped into CommitEncode, followed by the actual commitment to its output.

CommitVerify

Trait for commit-verify scheme.

CommitmentId

CommitmentLayout

CommitmentProtocol

Marker trait for specific commitment protocols.

Conceal

Trait that should perform conversion of a given client-side-validated data type into a concealed (private) form, for instance hiding some of the data behind hashed - or homomorphically-encrypted version.

ConvolveCommit

Trait for convolve-commit-verify scheme, where some data structure (named container) may commit to existing message using supplement and producing final commitment value. The commitment can’t be used to restore original message, however the fact of the commitment may be deterministically verified when the message and the supplement (now acting as a proof) proof are revealed.

ConvolveCommitProof

Proof type used by ConvolveCommit protocol.

Digest

Convenience wrapper trait covering functionality of cryptographic hash functions with fixed output size.

DigestExt

EmbedCommitProof

Proofs produced by EmbedCommitVerify::embed_commit procedure.

EmbedCommitVerify

Trait for embed-commit-verify scheme, where some data structure (named container) may commit to existing message (producing commitment data structure and a proof) in such way that the original message can’t be restored from the commitment, however the fact of the commitment may be deterministically verified when the message and the proof are revealed.

MerkleLeaves

TryCommitVerify

Trait for a failable version of commit-verify scheme.

VerifyEq

Trait for equivalence verification. Implemented for all types implementing Eq. For non-Eq types this trait provides way to implement custom equivalence verification used during commitment verification procedure.

Type Aliases

Ripemd160

RIPEMD-160 hasher.

Sha256

SHA-256 hasher.
