The Union network serves as an extremely effective zero-knowledge infrastructure layer for NFTs, DeFi, asset transfers, and general message passing. It doesn't rely on oracles, multi-signatures, MPC, or trusted third parties because it is based on consensus verification. Union employs cutting-edge BLS signatures and Zero-Knowledge Cryptography to provide the fastest and safest inter-blockchain communication protocol, IBC, globally.
Union has started a testnet and successfully gathered $4 million from investors including Nascent and Semantic Ventures. By transferring assets between chains and claiming testnet UNO tokens, you can join the testnet. When the testnet goes live, those who engage with it will probably receive an airdrop of their tokens.
