# kaal:claim:2992962-008

**Claim.** Anonymity survives the blockchain's permanent public record because a new private key can be created for each transaction, so although public key addresses are stored eternally, each transaction allows an entirely new cryptographically secured private identity.

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

**Holds when.**

- public-key cryptography as implemented in bitcoin and Ethereum

**Source quote.**

> So, while we can track the public key of the addresses of each transaction, and that information is stored eternally in the blockchain, each transaction allows for an entirely new private identity which is cryptographically secured.
