What is Union (U)?

Deep Dive

1. Purpose & Value Proposition

Union aims to be the foundational settlement and liquidity layer for a multi-chain world. It addresses the critical problem of isolated blockchains by providing a secure protocol for cross-chain communication. Its value lies in enabling seamless, trustless interoperability for developers, protocols, and asset issuers without relying on vulnerable bridges or oracles.

2. Technology & Architecture

The Union L1 is a zk-powered Proof-of-Stake blockchain. It uses advanced zero-knowledge cryptography—a method to verify information without revealing the underlying data—to aggregate and validate cross-chain messages securely. This architecture is designed for sub-second finality, supporting various execution environments like EVM, SVM, and MoveVM.

3. Tokenomics & Governance

U has a genesis supply capped at 10 billion tokens (Union Foundation). It serves three primary functions: as the gas token for a dynamic fee market; for staking to secure the network and earn emissions; and for cross-chain governance. Annual token emissions start at 6%, decreasing yearly to a long-term rate of 2%.

Conclusion

Fundamentally, Union is an infrastructure project building the connective tissue for blockchains, with its U token intrinsically linking demand for interoperability to network participation. As the ecosystem grows, will its technical approach to cross-chain security become the standard for institutional adoption?
