//! Note Commitment Trees.
|

|
|
|
//!
|
|
|
|
|
//! A note commitment tree is an incremental Merkle tree of fixed depth
|
|
|
|
|
//! used to store note commitments that JoinSplit transfers or Spend
|
|
|
|
|
//! transfers produce. Just as the unspent transaction output set (UTXO
|
|
|
|
|
//! set) used in Bitcoin, it is used to express the existence of value and
|
|
|
|
|
//! the capability to spend it. However, unlike the UTXO set, it is not
|
|
|
|
|
//! the job of this tree to protect against double-spending, as it is
|
|
|
|
|
//! append-only.
|
|
|
|
|
//!
|
|
|
|
|
//! A root of a note commitment tree is associated with each treestate.
