What is Union (U)?

Deep Dive

1. Purpose & Value Proposition

Union aims to solve blockchain fragmentation by providing a trustless interoperability layer. Unlike bridges that rely on vulnerable multisignature wallets or oracles, Union uses cryptographic verification to securely connect different execution environments like EVM, SVM, and MoveVM chains (Union). Its goal is to become a foundational settlement layer for the multi-chain economy, facilitating seamless liquidity flow and data transfer.

2. Technology & Architecture

The Union L1 is a zk-powered Proof-of-Stake blockchain. It uses zero-knowledge proofs—a cryptographic method that allows one party to prove a statement is true without revealing underlying data—to verify the state of connected chains. This "consensus verification" aims to eliminate the security risks common in traditional bridging. Validators stake U tokens to produce blocks and verify these proofs, securing the network.

3. Tokenomics & Utility

The U token has a capped genesis supply of 10 billion and serves three primary functions within the ecosystem (Union Foundation). First, it is the gas token for a dynamic fee market, used to pay for cross-chain operations like proof verification. Second, it is staked for network security in its PoS system. Third, it enables cross-chain governance, allowing holders to delegate and vote on proposals from any connected chain like Ethereum.

Conclusion

Fundamentally, Union is an ambitious infrastructure project seeking to securely unify blockchains through advanced cryptography, with its U token powering the network's core economic and security functions. Will its technical approach to verification become the standard for cross-chain interoperability?
