1/ Many frameworks for crosschain message passing embed trust assumptions, giving whitelisted actors administrative roles over the infrastructure. Can these frameworks be improved upon? 🧵 Unlocked by @union_build

2/ Union is architected as a layer 1 blockchain purpose-built to offer a maximally-decentralized modular interoperability protocol. The implementation seeks to address core issues in existing frameworks: centralization, latency, and cost. Entry is permissionless across all

3/ There are 3 core pillars to Union’s workflow: 1) CometBLS: a data-efficient consensus mechanism 2) Galois: a prover network to package validator signatures into a zero-knowledge proof (ZKP), and 3) Voyager: a relayer network to pass data-packets and proofs between chains,

4/ CometBLS iterates on Tendermint and CometBFT to offer a purpose-built consensus mechanism for crosschain actions. With CometBLS, the signatures and public keys of Union validators are aggregated to produce one signature with 1 public key. Message transfers need only contain twitter.com/168720120930682470...

5/ Voyager is Union's relayer network implementation. Relayers are responsible for delivering data packets with the source chain state to the Union Network, delivering the Union Network’s state to the prover network (Galois), and delivering the proofs produced by Galois to the

6/ Once consensus has been reached by Union validators, the resulting block header of the Union chain is relayed to the Galois prover network, a zero-knowledge consensus proving system. Galois then produces a ZKP of Union’s chain state, which is subsequently picked up by
