Module utxo_commitments 

UTXO Commitments Module

Implements cryptographic commitments to the UTXO set using Merkle trees. This module enables efficient UTXO set synchronization and verification without requiring full blockchain download.

Architecture

• Data Structures: UTXO, UTXO Set, UTXO Commitment
• Merkle Tree: Sparse Merkle Tree for incremental updates
• Peer Consensus: N of M peer verification model
• Verification: PoW-based commitment verification

Usage

use blvm_protocol::utxo_commitments::{UtxoMerkleTree, UtxoCommitment};
use blvm_consensus::types::{OutPoint, UTXO, Hash};

// Create UTXO Merkle tree
let mut utxo_tree = UtxoMerkleTree::new()?;

// Add UTXO
let outpoint = OutPoint { hash: [1; 32].into(), index: 0 };
let utxo = UTXO { value: 1000, script_pubkey: vec![].into(), height: 0, is_coinbase: false };
utxo_tree.insert(outpoint, utxo)?;

// Generate commitment
let root = utxo_tree.root();
let commitment = UtxoCommitment::new(root, 1000, 1, height, block_hash);
