Decentralized identity orchestration engine enabling multi-chain identity portability and automatic policy negotiation across blockchain ecosystems with decentralized governance.
PolyChainD is a decentralized identity orchestration engine that solves cross-chain identity management by creating a unified namespace across multiple blockchains. It supports self-sovereign identity principles while enabling interoperability through automated policy negotiation and identity attestation.
Native support for Ethereum, Polkadot, and Layer-2 solutions with pluggable consensus engines for emerging blockchain architectures.
Dynamic policy negotiation engine that resolves identity validation requirements between competing ecosystem rulesets.
Community-managed identity governance framework with staking-based dispute resolution mechanisms and on-chain policy execution.
Identity validation occurs at every access point with continuous attestation and zero-trust verification protocols.
