Crate tidecoin_consensus_core 

Shared Tidecoin consensus-validation core types.

This crate is the shared validation/engine layer used by higher-level Tidecoin crates.

In particular, similarly named PQ and validation-side types may exist in both tidecoin and consensus-core:

• tidecoin::* is the normal product-facing Rust API
• consensus-core::* is the lower-level shared verifier/engine API

Most downstream application code should start with tidecoin. Reach for consensus-core directly when you intentionally need shared validation, sighash, or lower-level engine building blocks.

Structs

InputsIndexError

Indexing error while computing a sighash.

Interpreter

High-level script verification context.

LegacySighash

Hash of a transaction according to the legacy signature algorithm.

NonStandardSighashTypeError

Error returned for a non-standard sighash type.

PqPublicKey

A verification-only post-quantum public key.

PqSignature

A raw post-quantum signature without the appended sighash byte.

PrecomputedTransactionData

Precomputed transaction data for witness-aware verification.

ScriptFlags

Wrapper for script verification flags.

ScriptStack

Minimal stack abstraction used by the interpreter.

SegwitV0Sighash

Hash of a transaction according to the SegWit version 0 signature algorithm.

Sighash512

Hash of a transaction according to the Tidecoin witness-v1 SHA-512 algorithm.

SighashCache

Efficiently calculates signature hash messages needed by consensus verification.

SighashTypeParseError

Error returned for failure during parsing one of the sighash types.

SpendContext

Input-specific data required to run the interpreter.

SpentOutputs

Typed spent outputs referenced by a transaction during verification.

TransactionContext

Borrows the transaction being verified.

VerificationFailure

Detailed failure information for a typed verification call.

WitnessProgram

Parsed witness program view over a scriptPubKey byte slice.

Enums

PqError

Verification-side PQ parse/verify error.

PqScheme

Identifies which post-quantum signature scheme a key or signature belongs to.

ScriptError

Script validation errors produced by the Tidecoin validation engine.

TidecoinValidationError

High-level validation errors produced by the Tidecoin validation engine.

TxSighashType

Hashtype of an input’s signature, encoded in the last byte of the signature.

Functions

validate_verification_flags

Validates raw verification bits against the shared Tidecoin engine contract.

verify_script_input
