Introducing Union
summary
Union builds a trustless bridge between Tendermint chains, Ethereum, Bitcoin and rollups using zero‑knowledge proofs and state verification to open permissionless IBC channels. Core pieces: a modified CometBFT called comBLS consensus (BLS signatures, adjusted voting) plus Galwa prover (built on narc) that runs on a single 64‑core server and produces proofs in ~12 seconds, Voyager relayer in Rust for event‑driven cross‑chain relay, and Hubble indexer serving Postgres via a single Graph API. Product has run 1 million blocks in four months and is IBC v0.47 compatible; testnet imminent.
