Wall Street Seeks Blockchain Guardrails Against North Korean Hackers

Wall Street and crypto clash over centralization to fight state-sponsored hackers like North Korea.

  • Beyond the Kelp DAO hack, Wall Street firms are increasingly concerned about their fiduciary duty to prevent state-sponsored bad actors from interacting with their financial systems.
  • Digital Asset‘s Yuval Rooz highlighted the Canton network‘s “guardrail” design as a solution to infiltration, a feature that remains contentious for crypto purists.
  • Rooz believes Arbitrum’s security council didn’t do “a bad thing” by freezing $71 million exposed in the Kelp DAO attack, sparking debate about DeFi‘s permissionless nature.
  • North Korean Hacking groups, which have stolen over $6 billion in crypto since 2017 according to a TRM Labs report, have evolved into sophisticated, long-term infiltration campaigns.
  • The tension between absolute decentralization and safety continues, with Rooz suggesting the ability to control bad actors may become a standard expectation.

North Korean-linked hacking groups are intensifying fears across both the cryptocurrency and traditional finance sectors following major losses like the Kelp DAO hack, according to Digital Asset co-founder Yuval Rooz. Wall Street institutions, in particular, are grappling with their fiduciary responsibility to ensure bad actors cannot engage with their systems, a concern Rooz’s team has fielded directly.

Rooz told Decrypt that questions about threats from North Korea arose even before Kelp DAO’s $290 million exploit rattled confidence last month. Consequently, he points to the design of the Canton network, a public, permissioned blockchain, as a potential solution through its implementable guardrails.

These guardrails allow participants to limit user control within subnets, which Rooz believes would challenge sophisticated groups like those from North Korea. However, this design has chafed crypto purists who argue it compromises the fundamental nature of a true blockchain by introducing centralization.

A similar debate about centralization erupted when Arbitrum’s 12-member security council moved to freeze $71 million left exposed by the Kelp DAO attackers. “Nobody should say that that’s a bad thing,” Rooz said, addressing the controversy.

He further argued that participants in DeFi often want all the freedom with none of the risks. Meanwhile, the differing approaches of major stablecoin issuers highlight this ongoing tension in practice.

After North Korean-linked attackers used its infrastructure, Circle said it wouldn’t lock down stablecoins without a court order. Tether, conversely, has worked with authorities to freeze funds connected to illicit finance.

Ultimately, the clash between absolute decentralization and safety shows no signs of abating. Rooz suggested that in a world of significant exploits, the ability to act against bad actors may shift from a controversy to a standard expectation.
