A Zcash transaction.

A transaction is an encoded data structure that facilitates the transfer of value between two public key addresses on the Zcash ecosystem. Everything is designed to ensure that transactions can created, propagated on the network, validated, and finally added to the global ledger of transactions (the blockchain).

Zcash has a number of different transaction formats. They are represented internally by different enum variants. Because we checkpoint on Sapling activation, we do not parse any pre-Sapling transaction types.

Variants

V1

A fully transparent transaction (version = 1).

Fields of V1

inputs: Vec<TransparentInput>

The transparent inputs to the transaction.

outputs: Vec<TransparentOutput>

The transparent outputs from the transaction.

lock_time: LockTime

The earliest time or block height that this transaction can be added to the chain.

V2

A Sprout transaction (version = 2).

Fields of V2

inputs: Vec<TransparentInput>

The transparent inputs to the transaction.

outputs: Vec<TransparentOutput>

The transparent outputs from the transaction.

lock_time: LockTime

The earliest time or block height that this transaction can be added to the chain.

joinsplit_data: Option<JoinSplitData<Bctv14Proof>>

The JoinSplit data for this transaction, if any.

V3

An Overwinter transaction (version = 3).

Fields of V3

inputs: Vec<TransparentInput>

The transparent inputs to the transaction.

outputs: Vec<TransparentOutput>

The transparent outputs from the transaction.

lock_time: LockTime

The earliest time or block height that this transaction can be added to the chain.

expiry_height: BlockHeight

The latest block height that this transaction can be added to the chain.

joinsplit_data: Option<JoinSplitData<Bctv14Proof>>

The JoinSplit data for this transaction, if any.

V4

A Sapling transaction (version = 4).

Fields of V4

inputs: Vec<TransparentInput>

The transparent inputs to the transaction.

outputs: Vec<TransparentOutput>

The transparent outputs from the transaction.

lock_time: LockTime

The earliest time or block height that this transaction can be added to the chain.

expiry_height: BlockHeight

The latest block height that this transaction can be added to the chain.

value_balance: i64

The net value of Sapling spend transfers minus output transfers.

shielded_data: Option<ShieldedData>

The shielded data for this transaction, if any.

joinsplit_data: Option<JoinSplitData<Groth16Proof>>
