The Multihash specification prepends algorithm identifier and length information to hash values, giving hash strings self-describing capability so that the parsing party can recover the digest's meaning without prior agreement on the algorithm.

UnverifiedThe self-describing nature of Multihash means that when upgrading the hash algorithm from SHA-256 to SHA-3, identifiers for existing data can still be correctly parsed without ambiguity.77% similarUnverifiedThe core idea of multihashing is to read a data block once and simultaneously feed it to the update functions of multiple hash algorithms, thereby amortizing the I/O cost to a single pass.72% similarUnverifiedThe Multihash encoding format is typically <varint algorithm code><varint digest length><digest bytes>, with the algorithm code for SHA2-256 being 0x12.71% similarUnverifiedA hash chain is formed by concatenating the hash of each message with the hash of the previous message and hashing again, creating a chain structure where modifying any intermediate message invalidates all subsequent hashes.67% similarUnverifiedWhat HashAgent encodes into the URL is the agent's configuration and logic definition (such as model references, system prompts, tool-calling logic, and runtime parameters), not the large model weights themselves.60% similar
