What is Union?
Union is designed to facilitate interoperability between blockchains using zero-knowledge proofs (ZKPs). It allows developers to build applications across different ecosystems, enhancing blockchain connectivity and functionality.
How Union works
Union employs consensus verification, where validators on one chain confirm consensus achieved by validators on another chain. It enables developers to utilize various execution environments or programming languages, such as Solidity, Rust, and Move. Through ZKPs, any chain or end user can verify a blockchain’s state across ecosystems using Union light clients or other proof aggregators. When a new blockchain integrates with Union, it receives a light client that verifies ZKPs generated from counterparty chains. This design allows for efficient communication and flexibility in supporting diverse blockchain networks.

Key characteristics
Union is modular, meaning it is built using interchangeable components that can be developed, updated, or replaced independently. It utilizes CometBLS, an enhanced blockchain consensus engine that builds upon Tendermint to address secure bridging and consensus verification challenges. Under CometBLS, the Union network can scale to over a hundred validators without compromising performance or bridging latency.

Risks
Digital asset prices can be volatile and can change materially. Users should verify the contract address and network before transferring assets. Self-custody requires secure private-key and recovery-phrase handling. Centralized platforms can involve operational, custody, and counterparty risk. Availability and regulatory treatment can vary by jurisdiction. Transaction finality and reversibility can differ by network.
Transfer and custody notes
Verify the asset name, network, and any supplied contract details before transferring. Verify destination address and network before sending assets. Review the custody method, including self-custody versus a third-party platform. Understand that transfers may be irreversible and that CoinLoom does not confirm exchange availability.
