# kaal:claim:3125827-010

**Claim.** If a blockchain cannot restart or regenerate autonomously after going offline or losing most active nodes, it needs social coordination between nodes; that requirement threatens anonymity and forces reliance on famous nodes.

**Type.** failure  **Support.** argued

**Holds when.**

- blockchain goes offline for a long period or has too few active nodes

**Source quote.**

> can the blockchain restart or regenerate autonomously13? Or is there a need for social coordination between the nodes? If so, anonymity is threatened and famous nodes are required.
