Digital Asset’s Canton Network is tackling one of DeFi’s thorniest problems. How do you give institutions blockchain efficiency without exposing them to nation-state hackers? These actors have stolen billions since 2017.
The solution: a public but permissioned blockchain. Participants can create customizable subnets with access controls. They’re designed to block sophisticated bad actors, according to Digital Asset.
Canton’s architecture lets institutions issue assets with what CEO Yuval Rooz calls “guardrails.” These are rules that can exclude known threats. Blockchain functionality stays intact.
“Institutions want blockchain efficiencies without opening systems to adversarial nation-states that have collectively stolen billions in crypto since 2017,” Rooz said.
The approach addresses a growing Wall Street concern. Firms face massive exploits—like the recent $290 million Kelp DAO hack. They also have fiduciary obligations to block sanctioned actors. Many are linked to North Korea.
Rooz emphasized Canton’s security measures counter months-long infiltration campaigns. These go far beyond simple phishing attacks.
The permissioned model has drawn criticism. Decentralization advocates argue that limiting user control undermines blockchain’s core principles.
Rooz defended the approach. He pointed to Arbitrum’s recent response to the Kelp DAO exploit.
“Freezing $71 million linked to the Kelp DAO exploit is responsible risk management,” he said. He framed the 12-member security council’s actions as pragmatic. Not a betrayal of permissionless ideals.
Canton can support fully open environments similar to Ethereum or Solana. But Rooz expects most consumer-facing applications will opt for safety parameters.
The safeguards are opt-in. Projects must actively enable them. Canton isn’t a universal fix for DeFi vulnerabilities.
The network’s primary selling point for large financial players? Giving them choice over who can interact with their applications.
The launch reflects a broader industry shift. Exploits are growing in scale and sophistication.
The debate mirrors tensions visible elsewhere in crypto. Stablecoin issuers Circle and Tether take different approaches toward freezing illicit funds.
Rooz predicts the power to “flip a switch” on bad actors will evolve. It’ll move from controversial compromise to standard feature of institutional DeFi infrastructure.
Security threats are becoming more complex. The question may shift from whether to implement controls to how those controls should work.
