Arbitrum Security Council member says blockchains run on social consensus, not just code

The crypto industry loves to repeat “code is law.” Griff Green, a member of the Arbitrum Security Council, would like to gently push back on that.

In a Phemex interview published on April 23, 2026, Green argued that blockchains are not absolutely immutable. They depend on community agreement to function. That framing matters a lot more when the person saying it just helped freeze roughly $71 million in stolen funds two days earlier.

## What happened with the KelpDAO freeze

On April 21, 2026, the Arbitrum Security Council executed what appears to be a first-of-its-kind action for a major Layer 2 network. The Council used its multi-signature authority to transfer 30,766 ETH, linked to a KelpDAO exploit, from the attacker’s address into a frozen wallet on Arbitrum One.

That’s roughly $71 million worth of ETH, locked in place by a committee of 12 people. Not a court order. Not a protocol-level bug fix. A governance body making a judgment call in real time.
