DID:ION leverages the blockchain-agnostic Sidetree protocol to anchor tens of thousands of DID/DPKI (Decentralized Public Key Infrastructure) operations into one single on-chain Bitcoin transaction. These transactions are encoded so DID:ION nodes can fetch, store, and replicate hash-associated DID operation batches via IPFS (InterPlanetary File System). DID:ION nodes process operations in batches that independently arrive at the corrected DPKI state for system IDs, without the need for consensus mechanisms, blockchain, or sidechain. Nodes can work in parallel to fetch, process, and assemble DIDs, allowing nodes to run tens of thousands of operations per seconds. This allows Zion to create a robust decentralize identifier network that does not require trusted intermediaries, centralized authorities, or secondary consensus mechanisms.
