The current exploit on Harmony’s Horizon Bridge revealed the natural flaws with multisig admin keys that leave projects as well as their users “one small slipup” from deep trouble.
Two crypto project leads expressed their concern the growth of the multi-chain ecosystem might be hampered through multisig contracts because of the dangers they pose with bridges keeping crypto funds safe.
Multisig refers back to the dependence on multiple visitors to approve a transaction. The multichain ecosystem may be the conglomeration of countless blockchains with different consensus algorithms that frequently interact through token bridges.
Founding father of the Moonbeam blockchain Derek Yoo told Cointelegraph he advocates for brand new methods to security that aim to accept component of human error from the equation. Yoo stated the multichain ecosystem is seeing elevated increase in usage because of the “desire to maneuver assets to various chains” however that it requires far better safety measures.
“There are natural weaknesses within the multisig approach that familiarizes you with hacking risk. It requires one small slipup and you’re in deep trouble.”
Moving assets between chains usually requires token bridges, such as the Horizon Bridge that was exploited on June 23 for around $100 million in crypto assets. Horizon was compromised when two signee keys because of its multisig contract were found by an assailant.
Yoo noticed that the multisig approach could be the standard for that industry at the moment, but it’s not even close to a defacto standard. In the estimation, you will find a lot more secure designs that may be carried out to bridge tokens, for example utilizing a separate proof-of-stake (PoS) network for transfers. He feels that although developers need to make compromises to get at chains with many different activity:
“Communication between chains in the blockchain level may be the bleeding edge and is easily the most secure kind of bridging.”
Chief executive officer from the Mina Foundation which developed the Mina blockchain Evan Shapiro shares Yoo’s distrust from the multisig approach because of the more complex measures open to the now. He feels the greatest problem facing the multichain ecosystem is its over-reliance upon trust. He told Cointelegraph on June 30 that
“The apparent problem is dependant on third-party custodians becoming reliable intermediaries for bridges.”
In the view, the perfect could be for blockchains to become verified by one another, but acknowledges that that’s infeasible and inefficient. An alternate would be to utilize zero-understanding proofs that compress and verify the huge quantity of data stored on blockchains.

Shapiro distilled the dilemma presented by token bridges lower to who or what entity users are placing their rely upon when bridging tokens. He stated that no matter when the bridge may be the first party, out of the box the situation using the Horizon Bridge, or even the 3rd party. “This isn’t about the introduction of the code,” he stated.
“It talks to the potential risks of custodial bridges. For those who have a custodial bridge, a set number of individuals can compromise it.”
