However, it will become necessary for approval and dispute checkers to check that the pov_hash in the descriptor matches the trie commitment computed from the full PoV data. ![]() Note that the erasure root in the candidate receipt is computed over an erasure-coding on the full PoV data, and will not change. ![]() Storing the number of chunks is important, so validators can tell immediately from the trie root commitment whether the PoV is oversized.įor the pov_hash in the candidate descriptor, it is defined to either be hash(PoV) or hash(PoVTrieCommitment). The rightmost chunk may have size less than 32KiB, so the upper bound on the size is predicted by n_chunks * CHUNK_SIZE. This is the root hash of the merkle trie as well as the number of chunks contained in the trie. The trie is computed as a mapping from indices i to the chunk hash. Const CHUNK_SIZE = 32 KiB struct PoVTrieCommitment ( root_hash, n_chunks )
