How does Sign work?

The Sign ecosystem is composed of four main products:

Sign Protocol: Facilitates the creation and verification of attestations across multiple chains.

TokenTable: A platform to distribute tokens through methods such as airdrops, acquisition, and unlock schedules.

EthSign: A decentralized application (DApp) for executing digital agreements on-chain.

SignPass: A system for on-chain identity registration and verification. It helps users prove their identity online.

Sign Protocol

The Sign Protocol is like a digital notary. It allows users to issue and verify claims about things like identity, ownership, or agreements. It works across various blockchains and has built-in privacy features using encryption and zero-knowledge proofs. Some of its main features include:

Omni-chain capability: Supports attestations across different blockchains.

Data structure: The attestations are built around key-value pairs, making them highly adaptable to different data formats.

Privacy features: Data can be encrypted or obscured using zero-knowledge proofs, ensuring that users can prove claims without revealing underlying data.

Incentives for developers: Encourages innovation through funding and support for developers who integrate the Sign protocol.

Data security: Fallback mechanisms (such as Arweave storage) ensure that data is not lost, even if blockchain networks face disruptions
