FAQ for the Human Network

What are some potential use cases for Human Network?

Human Network can be used for

• Decentralized identity applications where you must generate keys from user data

• Wallets or dApps that want to generate keys from user data, e.g. identity, biometrics, social logins,

• Compliant ZK identity where companies must hold provably encrypt data they can solely decrypt when predefined conditions are met

• Provable encryption identities or secret keys as collateral for assets to in DeFi. E.g. undercollateralized lending that reveals the identity of users that default.

How is Human Network different from other decentralized identity solutions?

Human Network is a unique primitive built for identity and wallets. It is a tool DID and wallets can utilize rather than a full-stack identity solution itself.

How does Human Network leverage EigenLayer or Symbiotic?

Human Network integrates with EigenLayer and Symbiotic to enhance security and scalability. Restaking protocols enable Human Network to leverage billions of dollars worth of ETH securing Ethereum.

How does Human Network handle key management?

Human Network provides human keys, a secure and user-friendly way to manage digital keys. Users can generate, recover, and use keys from their own accounts, identities, and attribuets privately without relying on centralized authorities.

How does Human Network handle privacy?

Human Network cannot see your data under the

• Discrete logarithm assumption

• Noncollusion assumption of operators (mostly doxxed, with highly stringent decentralized inclusion criteria) and optionally, semi-trusted node(s)

This is by leveraging Threshold Verifiable Oblivious Pseudorandom Function (VOPRF), and similar cryptographic primitives. There is no need to trust the developers of Human Network since the trust is in math -- we can't see user data.

Can you explain the concept of recoverable keys in Human Network?

Human Network lets users create digital wallets with keys that can be recovered if lost. These keys are generated from identity proofs, so there's no need for centralized custodians. If you forget your password or lose your device, you can still recover your wallet using the identity information you provided when you set it up.

How does Human Network prevent overreliance on centralized identities?

Human Network achieves decentralization by operating as a threshold network. In a threshold network, multiple nodes (computers) collaborate to perform tasks, so no single node has complete control. Human Network's nodes work together to carry out complex calculations using linear secret sharing. This approach eliminates the need for a central authority and single point of failure, reducing the risk of data breaches and making the system more resilient.

What are the benefits of using threshold networks in Human Network?

Threshold networks improve security and decentralization. In Human Network, the complex math needed for security is split across multiple nodes using advance threshold cryptographic primitives. This means there is no single point of failure—if some nodes are compromised, the system still works safely. This reduces dependence on centralized entities and makes the network stronger and more reliable.

What makes Human Network's cryptographic approach unique?

Human Network's cryptographic methods are unique due to their privacy-preserving features like Threshold Verifiable Pseudorandom Function (VORF) and ZK-friendly elliptic curves. The combination of these methods provides strong security while making sure that user data remains private.

How does Human Network manage cryptographic key distribution among nodes?

Human Network uses a distributed key generation (DKG) protocol, where nodes collaboratively generate and manage cryptographic keys without relying on a centralized authority. The DKG protocol is processed in such a way that the overall network secret is never generated or recombined. It consists of a sequence of partial secret generations on each node side.

How does Human Network handle the lifecycle of cryptographic keys?

Human Network performs a key resharing protocol at every epoch so that if individual nodes' keys are compromised, the network's key remains safe without having to be rotated. Instead, individual nodes' keyshares change at every epoch. We have an additional security mechanism that prevents any party from decrypting key materials shared in previous epochs.

What consensus mechanism does Human Network use and why?

Human Network can handle all requests without consensus, asynchronously! It still has to account for fees in a shared global state, so for this it uses Othentic consensus.

What approach does Human Network use for secure communication between nodes?

Human Network uses secure communication protocols such as TLS/SSL with mutual authentication to ensure data transmitted between nodes is encrypted and authenticated.
