Citrea: Bitcoin's first ZK rollup and the BitVM-based Clementine bridge
Post167 words
Citrea batches transactions off-chain, proves them with RISC Zero's zkVM and Boundless, and inscribes proofs and state diffs on Bitcoin, enabling EVM contracts without protocol changes. The Clementine bridge uses BitVM for 1-of-N trust-minimized BTC bridging.
Key claims
Raised $16.7M from Founders Fund, Galaxy, DAO5, Mirana and others
Clementine bridge offers 1-of-N security vs federated models
Only proofs and state diffs are posted to Bitcoin
$BTC ATH is cool.
But ZK-powered app layer programmability on top of Bitcoin transforming $BTC from a passive store of value into the foundation of DeFi is even cooler.
It's why I have recently been looking into @citrea_xyz:
- Bitcoin's first ZK rollup enabling EVM-compatible smart contracts while inheriting Bitcoin's security.
- Batches 1000s of txs processed off-chain, which are ZK proven using
RISC Zero's zkVM and @boundlesshq (ZK proof marketplace), inscribing only proofs + state diffs on Bitcoin.
- Its Clementine bridge uses BitVM for trust-minimized BTC bridging (1-of-N security vs federated models).
- Transforms Bitcoin into programmable platform without protocol changes or compromising decentralization.
- $16.7M raised from @foundersfund, @galaxyhq, @daofive, @mirana, @Maven11Capital, and others, with mainnet approaching 2025 after audits and trusted setup ceremony are completed.
- Pioneering ₿apps ecosystem with a bunch of $BTC native DeFi protocols already building (stablecoins, DEXs, lending).
Recommend to DYOR anon.
Will also be dropping a comprehensive piece on Citrea and the ₿apps ecosystem soon™, so stay tuned!
