"IPv8 is a networking layer which offers identities, communication with some robustness, and provides hooks for higher layers. For instance, our Internet-deployed reputation functions and ledger-based storage of reputation data. In combination with our Trustchain, IPv8 is designed as a mechanism to build trust. Each network overlay offers network connections to known digital identities through public keys. Overlays are robust against several network problems and security issues. Using a custom NAT-traversing DHT to find the current IPv4 network address, IPv8 keeps the network connectivity going, even as the IPv4 addresses change. Each network overlay keeps track of a number of neighbors and occasionally checks if they are still responsive.
IPv8 offers global connectivity through integrated UDP NAT puncturing, announcement of your identity claim and a web-of-trust. IPv8 has an integrated attestation service. You can use IPv8 for official verification that something is true or authentic, according to a trustworthy attestor. By using zero-knowledge proofs we attempt to minimize privacy leakage."
