The latest hack of Axie Infinity’s Ronin bridge reveals how proof-of-stake (PoS) chains nonetheless battle with a elementary flaw of their design, with pace and power effectivity prioritized over safety, an analyst at crypto change Huobi has mentioned.
“This hack displays the persevering with challenges that blockchains and operators face in balancing person expertise and safety,” Huobi Analysis Institute head Flora Li mentioned in a commentary on Wednesday, suggesting that the low variety of nodes on the Ronin community was a elementary downside.
Though Axie Infinity (AXS) developer Sky Mavis has “pledged to lift the variety of required nodes to eight,” this isn’t sufficient, Li mentioned. She argued that,
“It nonetheless does not remedy the elemental downside of how proof-of-stake blockchains can hold transactions quick, user-friendly, and energy-efficient with out compromising safety.”
The analyst added that Ronin has taken “shortcuts to alleviate community bottlenecks,” and mentioned that slicing down the variety of nodes on the community has made it “simpler for hackers to take advantage of.”
The feedback from Huobi’s Li got here after information broke on Tuesday that the Ronin bridge, which is used to attach the Ronin community to different blockchains, had been drained by hackers for ETH 173,600 and USDC 25.5m, now price some USD 615m.
Ronin is a sidechain to the Ethereum (ETH) blockchain developed particularly for Sky Mavis’ crypto-based play-to-earn recreation Axie Infinity.

Regardless of the funds already being on the transfer, Zirlin insisted that there’s an opportunity that the hackers can nonetheless be recognized.
Notably, the hacking incident was confirmed nearly every week after it occurred, and the Ronin crew’s response to it was to halt the Ronin bridge and a associated decentralized change (DEX).
As could be anticipated, this was rapidly identified by some proof-of-stake critics on Twitter:
In the meantime, different business gamers additionally hinted {that a} lack of give attention to safety and decentralization might be in charge for the assault.
EA Sports activities, a contributor to DeFi protocol Harvest Finance mentioned in an emailed remark that Ronin is a sidechain secured by 9 validators, whereas solely “5 (+50%)” are wanted to assault the community – “the attackers obtained entry to the system that operates 4 of the nodes, and located a bug to entry one other node.”
They added that,
“This centralization of the validators made it a lot simpler to compromise safety and one other instance of why decentralization is essential.”
An analogous concern was additionally shared by Kadan Stadelamn, chief expertise officer of DeFi platform Komodo (KMD), who mentioned the hack “reveals why centralized cross-chain bridge options might threaten the adoption of cryptocurrencies.”
“Having solely 9 validators for the Ronin bridge, and 4 belonging to the identical particular person, is regarding,” he mentioned, including that pooling all person funds into only one pockets handle “is the precise definition of centralization.”
In the meantime, Ryan Lewis, Expertise Guide at digital asset safety supplier Coincover, mentioned that the Ronin hack reveals “the traditional challenges of usability trumping safety when these applied sciences are so younger.”
“There isn’t any doubt this can proceed to be the case because the crypto business matures however the stakes are extraordinarily excessive and safety can definitely not take a again seat,” he mentioned in an emailed remark.
