pub enum TxVersion {
Sprout(u32),
V3,
V4,
V5,
}
Expand description
The set of defined transaction format versions.
This is serialized in the first four or eight bytes of the transaction format, and
represents valid combinations of the (overwintered, version, version_group_id)
transaction fields. Note that this is not dependent on epoch, only on transaction encoding.
For example, if a particular epoch defines a new transaction version but also allows the
previous version, then only the new version would be added to this enum.
Variants§
Sprout(u32)
Transaction versions allowed prior to Overwinter activation. The argument MUST be
in the range 1..=0x7FFFFFFF
. Only versions 1 and 2 are defined; 3..=0x7FFFFFFF
was allowed by consensus but considered equivalent to 2. This is specified in
§ 7.1 Transaction Encoding and Consensus.
V3
Transaction version 3, which was introduced by the Overwinter network upgrade and allowed until Sapling activation. It is specified in § 7.1 Transaction Encoding and Consensus.
V4
Transaction version 4, which was introduced by the Sapling network upgrade. It is specified in § 7.1 Transaction Encoding and Consensus.
V5
Transaction version 5, which was introduced by the NU5 network upgrade. It is specified in § 7.1 Transaction Encoding and Consensus and ZIP 225.
