Gnosis, the team behind 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 conversation with Cointelegraph, Gnosis CEO Martin K\u00f6ppelmann stated that the new aggregator should make bridges more secure by requiring more than one bridge to validate a withdrawal before it can be confirmed.<\/p>\n
Multiple bridge protocols have already committed to integrating with Hashi, including Succinct Labs, DendrETH, ZK Collective, Connext, Celer, LayerZero, Axiom, Wormhole and LI.FI, according to the announcement.\u00a0<\/p>\n
Over $2 billion was stolen<\/a> from bridges in 2021 and 2022, according to a report by Token Terminal. Bugs in the code have caused some bridge hacks, whereas others have been caused by the attacker taking over a multi-sig governance wallet.<\/p>\n According to K\u00f6ppelmann, Hashi can provide the first step towards making these cross-chain transactions more secure throughout the blockchain ecosystem, by requiring withdrawals to be validated by multiple bridges instead of just one:<\/p>\n \u201cHashi is about essentially creating this aggregator that can use different bridges and basically say they all need to agree to the same message […] If they do, great, then we can be really, really certain that this message is actually real and if they disagree […] Then we know we need to escalate to governance, we need to halt the bridge.\u201d<\/p><\/blockquote>\n K\u00f6ppelmann also emphasized that Hashi helps to prevent multi-sig governance attacks because it allows a protocol to prevent governance from intervening if there is no disagreement between individual bridges.<\/p>\n \u201cHere you can have this nice tradeoff where you say \u2018the governance is not allowed to do anything,\u2019 so it cannot interfere with the system unless there is explicitly a conflict or a bug,\u201d\u00a0he explained. \u201cSo as soon as those bridges that are supposed to report on the same thing […] Disagree, well then governance is allowed to interfere, otherwise governance has no role. That\u2019s Hashi.\u201d<\/p>\n Related: <\/strong>Uniswap\u2019s BNB deployment should use multiple bridges, claims LIFI CEO<\/strong><\/a><\/em><\/p>\n Hashi is open source and available on GitHub.<\/p>\n The idea of a multi-bridge aggregator rose to prominence<\/a> during the Uniswap bridge debate in December and January. Although Wormhole was ultimately chosen<\/a> as Uniswap\u2019s bridge provider, representatives from Celer, LiFi, and deBridge, as well as other participants concluded that a multi-bridge aggregation solution needed to be implemented going forward.<\/p>\n<\/div>\n
