# kaal:claim:3606663-036

**Claim.** Consensus in decentralized systems presents a two sided cost problem: creating consensus raises the costs of prepping, processing, and storing information, while reducing the number of computational checks increases the risk of collusion attacks that could change the record.

**Type.** mechanism  **Support.** argued

**Holds when.**

- public distributed consensus systems
- information distributed to and validated by all parties

**Source quote.**

> Creating consensus requires increase costs of prepping, processing, and storing information.333 On the other hand, fewer computational checks for consensus increase the risk of collusion attacks that could change the record.
