zcash_primitives::transaction

Struct TxId

pub struct TxId(/* private fields */);
Expand description

The identifier for a Zcash transaction.

  • For v1-4 transactions, this is a double-SHA-256 hash of the encoded transaction. This means that it is malleable, and only a reliable identifier for transactions that have been mined.
  • For v5 transactions onwards, this identifier is derived only from “effecting” data, and is non-malleable in all contexts.
