What is Union (U)?

Deep Dive

1. Purpose & Value Proposition

Union aims to solve blockchain fragmentation by providing a secure, trustless interoperability layer. It enables seamless asset and data transfers across thousands of chains—including Ethereum, Babylon, and Base—without relying on trusted third parties or oracles. This positions Union as a foundational infrastructure for the multi-chain future, similar to a decentralized SWIFT for modern finance (Union Foundation).

2. Technology & Architecture

The network is a zk-powered Proof-of-Stake (PoS) Layer 1. It uses zero-knowledge (ZK) cryptography to verify state proofs from connected chains, ensuring security and enabling sub-second settlement. This ZK interop layer eliminates common bridge vulnerabilities associated with private keys. Validators stake U to produce blocks and verify proofs, decentralizing network security.

3. Tokenomics & Utility

U has a capped genesis supply of 10 billion tokens. Its utility is threefold: as gas for network operations, as a staking asset for PoS security, and for cross-chain governance. The initial annual token emission is 6%, decreasing yearly to a long-term rate of 2%. Nearly 60% of the genesis supply is allocated to community incentives, ecosystem growth, and DAO treasury, emphasizing alignment with network participants.

Conclusion

Fundamentally, Union is building a secure, scalable base layer for cross-chain communication, with U serving as its economic and governance engine. How effectively will its ZK-proof architecture attract developers and become the default settlement layer for the multi-chain economy?
