Union @ union-build Season 0 😵 ‍ 💫 Coming to an end, the first season quietly kicked off on July 23rd. If you brush your mouth, remember to bind and push: http://app.union.build/yaps Airdrop angle: 1) Participate in v2 testing network http://app.union.build Bind wallets, Twitter, and GitHub. Test network XP may be converted into U tokens proportionally, and the specific allocation mechanism will be confirmed after the main network is released. 2) Holding NFT and obtaining XP 3) Join Dc: Follow the announcements and developers channels, submit feedback or bug reports (via support tickets), which can increase community contribution 4) You can build Union components (such as Uniond and Voyager) through GitHub (unionlabs/union), enter the development environment, and contribute code. 5) Galaxy @ Galxe and other missions Union Build is a highly efficient interoperability protocol based on zero knowledge proofs, aimed at connecting all blockchains and Rollup, covering various ecosystems such as EVM, Cosmos/IBC, etc. Its core goal is to achieve cross chain communication, asset transfer, and NFT interoperability through decentralization and trust minimization, addressing the security and efficiency issues of traditional bridging solutions. Core Technology: Zero knowledge proof: Verify the consensus of the entire chain through ZK, ensuring fast, secure, and low-cost cross chain operations. CometBLS: A consensus engine upgraded based on Tendermint, utilizing BLS signatures to reduce proof time and supporting efficient bridging. Modular design: Supports multiple execution environments (EVM, SVM, altVM) and programming languages (Solidity, Rust, Move), allowing developers to flexibly build cross chain applications. Voyager: An off chain role that supports the IBC protocol and is responsible for the transmission of cross chain data packets and proofs. State Lenses: Packet Forward Middleware superior to IBC, reducing expensive transfer and re execution costs. Application scenarios: Message passing: Supports collaboration between cross chain decentralized exchanges (DEX) and lending protocols. Asset transfer: realize cross chain transfer of native assets, pledged derivatives, etc. Cross chain NFT: Efficient mapping and encoding of NFT data, supporting standards such as ERC-721 and ICS-72. Bitcoin ecosystem support: Collaborate with Bitcoin security networks such as Babylon, Corn, BOB, etc. to support Bitcoin LST and promote the development of BTCfi. Vision: Union is committed to building an interoperability layer that can connect thousands of chains, eliminate ecosystem silos, promote permissionless composability of modular blockchain, and provide infrastructure for the future multi chain world. Financing situation: Union Labs has completed a $16 million financing, including a $12 million Series A round led by Gumi Cryptos Capital and LongHash Ventures in December 2024.
