Crate merkle_tree_accumulator 

Merkle Tree Accumulator

A simple, append-only Merkle tree-based cryptographic accumulator.

Features

• Multiple hashers: SHA-3, BLAKE3, and Poseidon
• Batch proofs: Efficient multi-leaf proof generation and verification
• no_std compatible: Works without standard library

Example

use merkle_tree_accumulator::{Hash, Sha3Accumulator};

let mut acc = Sha3Accumulator::new();
acc.add(Hash::from_data(b"leaf 1")).unwrap();
acc.add(Hash::from_data(b"leaf 2")).unwrap();

let proof = acc.prove(&[0]).unwrap();
acc.verify(&proof, &[Hash::from_data(b"leaf 1")]).unwrap();

Feature Flags

• std (default): Standard library support
• blake3: BLAKE3 hasher
• poseidon: Poseidon hasher for algebraic circuits
