Day 5️⃣ – Union bringing ZK to Cosmos and Beyond 🌌

Cosmos IBC is one of the most trusted and widely adopted bridging standards. But it still depends on running full light clients which are hard to deploy on EVM chains or rollups. @union_build solves this by using CometBLS + ZKPs to simulate light clients without the overhead

Union takes the secure design of IBC and makes it portable enabling Cosmos chains to connect with Ethereum, zkEVMs, rollups and more. It opens up a universe where every chain can speak IBC even if they weren’t built for it.

Think of Union as the universal translator for blockchains. One that speaks pure math, not multisig oracles. Cosmos chains become verifiable on Ethereum. Ethereum blocks can be proven to other systems. And everything becomes composable.
