HiDID is a public, permissionless, Decentralized Identifier (DID) network that implements the blockchain-agnostic DsLink protocol on top of (as a 'Layer 2' overlay) to support DIDs/DPKI (Decentralized Public Key Infrastructure) at scale.
-
HiDID is public and permissionless - the system is decentralized, no company, organization, or group owns/controls the identifiers and DPKI entries in the system, and no one dictates who can participate.
-
HiDID is not a sidechain or consensus system - the network nodes do not require any additional consensus mechanism.
By leveraging the blockchain-agnostic DsLink protocol, Hid makes it possible to anchor tens of thousands of DID/DPKI operations on a target using a single on-chain transaction. The transactions are encoded with a hash that HiDID nodes use to fetch, store, and replicate the hash-associated DID operation batches via IPFS. The nodes process these batches of operations in accordance with a specific set of deterministic rules that enables them to independently arrive at the correct DPKI state for IDs in the system, without requiring a separate consensus mechanism, blockchain, or sidechain. Nodes can fetch, process, and assemble DID states in parallel, allowing the aggregate capacity of nodes to run at tens of thousands of operations per second.
