Module types 

Essential Bitcoin types for consensus validation

Structs

Bip54BoundaryTimestamps

BIP54 timewarp: timestamps of boundary blocks for period-boundary checks.

Block

Block: ℬ = ℋ × 𝒯𝒳*

BlockContext

Block validation context

BlockHash

Block hash: newtype wrapper for type safety

BlockHeader

Block Header: ℋ = ℤ × ℍ × ℍ × ℕ × ℕ × ℕ

BlockHeight

Block height: newtype wrapper for type safety

OutPoint

OutPoint: 𝒪 = ℍ × ℕ

ScriptContext

Script execution context

SharedByteString

Shareable script_pubkey for UTXO: small scripts use inline storage; longer use Arc<[u8]>. Clone is cheap (inline copies up to 64 bytes, shared is Arc::clone). Serde matches ByteString.

TimeContext

Time context for consensus validation

Transaction

Transaction: 𝒯𝒳 = ℕ × ℐ* × 𝒯* × ℕ

TransactionInput

Transaction Input: ℐ = 𝒪 × 𝕊 × ℕ

TransactionOutput

Transaction Output: 𝒯 = ℤ × 𝕊

UTXO

UTXO: 𝒰 = ℤ × 𝕊 × ℕ

Enums

ForkId

Stable identifier for each consensus-affecting fork (BIP or soft-fork bundle).

Network

Network type for consensus validation

ValidationResult

Validation result

Functions

utxo_set_insert

Insert owned UTXO into UtxoSet (wraps in Arc). Convenience for tests and one-off inserts.

Type Aliases

ByteString

Byte string type

Hash

Hash type: 256-bit hash

Integer

Integer type

Natural

Natural number type

UtxoSet

Witness

Witness data: stack of witness elements (SegWit/Taproot)
