Gnosis launches Hashi bridge aggregator to help prevent hacks

Gnosis, the squad down Gnosis Safe multi-sig and Gnosis Chain, has launched a hash oracle aggregator for blockchain bridges, according to an announcement from the company. In a speech with Cointelegraph, Gnosis CEO Martin Köppelmann stated that the caller aggregator should marque bridges much unafraid by requiring much than 1 span to validate a withdrawal earlier it tin beryllium confirmed.

Multiple span protocols person already committed to integrating with Hashi, including Succinct Labs, DendrETH, ZK Collective, Connext, Celer, LayerZero, Axiom, Wormhole and LI.FI, according to the announcement. 

Over $2 cardinal was stolen from bridges successful 2021 and 2022, according to a study by Token Terminal. Bugs successful the codification person caused immoderate span hacks, whereas others person been caused by the attacker taking implicit a multi-sig governance wallet.

According to Köppelmann, Hashi tin supply the archetypal measurement towards making these cross-chain transactions much unafraid passim the blockchain ecosystem, by requiring withdrawals to beryllium validated by aggregate bridges alternatively of conscionable one:

Hashi is astir fundamentally creating this aggregator that tin usage antithetic bridges and fundamentally accidental they each request to hold to the aforesaid connection [...] If they do, great, past we tin beryllium really, truly definite that this connection is really existent and if they disagree [...] Then we cognize we request to escalate to governance, we request to halt the bridge.

Köppelmann besides emphasized that Hashi helps to forestall multi-sig governance attacks due to the fact that it allows a protocol to forestall governance from intervening if determination is nary disagreement betwixt idiosyncratic bridges.

“Here you tin person this bully tradeoff wherever you accidental ‘the governance is not allowed to bash anything,’ truthful it cannot interfere with the strategy unless determination is explicitly a struggle oregon a bug," helium explained. "So arsenic soon arsenic those bridges that are expected to study connected the aforesaid happening [...] Disagree, good past governance is allowed to interfere, different governance has nary role. That’s Hashi.”

The thought of a multi-bridge aggregator rose to prominence during the Uniswap span statement successful December and January. Although Wormhole was ultimately chosen arsenic Uniswap’s span provider, representatives from Celer, LiFi, and deBridge, arsenic good arsenic different participants concluded that a multi-bridge aggregation solution needed to beryllium implemented going forward.
