Succinct’s Ethereum ZK Light Client To Secure $40M+ TVL on Gnosis Chain’s OmniBridge

Eight months ago, Succinct announced the first demo application that uses their unique implementation of “proof of consensus” for Ethereum: a bi-directional bridge between Goerli testnet and Gnosis Chain.

Almost a year later, we are extremely excited to announce the significant security upgrade for Gnosis Chain’s OmniBridge. Succinct’s Ethereum ZK light client will be officially integrated soon to secure the Gnosis OmniBridge on Mainnet! Over $40M TVL and >$1.5B in stablecoin asset flow to date will be secured by Succinct’s ZK Proof of Consensus for Ethereum.

WHAT DOES THIS MEAN FOR USERS
While plans are in place to upgrade all of our native bridges, only OmniBridge users need to be aware of the zk light client integration.

Transactions will now be verified by the zk light client on the OmniBridge. Ethereum finality and proof of generation will take approximately 20 minutes for each bridged transaction. Users requiring faster transaction times should seek 3rd party bridge solutions.

Please stay tuned for more detailed information including the hard date and time for when the OmniBridge zk light client integration will go live!

We share Succinct’s belief that the next era of cross-chain bridging between different L1 blockchain ecosystems will be powered by zk light clients. We are excited to implement their zero-knowledge proof technology to secure the Gnosis Chain OmniBridge. If you love zero-knowledge proofs and bridges, go try out the OmniBridge and bridge to Gnosis Chain!

If you’re a developer building applications on the AMB and Gnosis Chain has yet to speak with you, please fill out this form: https://forms.gle/AiiWRZX7rdnkkvoq8

Sharing your contact info will ensure that your product continues without interruption.

Mentioned document only specifies how transfers from Ethereum to Gnosis will work. What about Gnosis to Ethereum transfers?
Seems to me that securing only one bridge direction doesn’t add any security benefit at all, as long as the reverse direction is still vulnerable to potential multisig keys leakage (e.g. check out recent PolyNetwork hack).

Hi Mantas -

The light client integration for the GC → Eth route is on the roadmap and actively being worked on. Check out the roadmap here Succinct’s Ethereum ZK Light Client and the Road to Trust Minimzed Bridges with Hashi - Gnosis Chain

Hashi is live and dramatically improves bridge security. You can read more here.
