WebJul 18, 2024 · At the core of SPAR is a novel cryptographic hash accumulator called coded Merkle tree (CMT). Starting from the bottom, CMT iteratively encodes layers of the tree and uses the hashes of the coded layer as the data for the next layer. A light node can detect the availability of the entire tree through the Merkle proofs of bottom layer leaves.
