September will be a season of harvest, as some new and old projects have coincidentally announced their TGE around this time. Although the timing of sowing may have been months or even years ago, it is still important to have a basic understanding of market trends. Before writing today, I mentioned one of the new three pillars of ZK, @union_build, which recently announced its tokenomics. Let's first look at the fundamentals. ❶ Union is a zero-knowledge cross-chain interoperability protocol dedicated to building a trustless cross-chain messaging and asset bridging infrastructure. ❷ It has currently raised $16 million in funding, with investors including gCC, Longhash, Foresight, and others. ❸ It has completed over 325 million testnet transactions, accounting for 97% of the external TVL in Babylon Genesis. It has formed partnerships with Berachain, Polygon, Celestia, Avalanche, and others. Differentiation and Advantages Unlike our traditional perception of cross-chain bridges, Union is creating a protocol layer that connects different chains. In simple terms: Union deploys a lightweight client for all chains that integrate it, providing a standardized zk proof generation for all cross-chain transactions. This is thanks to Union's lack of centralized dependencies. Unlike traditional cross-chain protocols that rely on multi-signatures and external validation nodes, it operates entirely on zero-knowledge proofs. This is also why many BTCFi protocols and mainstream L1/L2 have chosen it. Currently, Union has achieved interoperability among the chains shown in the image below, and plans to illuminate the entire landscape in the future, achieving cross-chain interoperability across EVM + Cosmos + Solana. I have compiled the current status of several cross-chain protocols that have already issued tokens, which can serve as a reference for estimating Union's FDV.
