## Bitauth
[Bitauth](https://github.com/bitauth/bitauth2017/blob/40e84a073be3e8689e6f85b31a5b6536a3524238/bips/0-bitauth.mediawikis) (2016) is an identity resolution and message authentication protocol which uses transactions to define and update the public claims and signing requirements of identities. CashTokens' [use of Transaction IDs as Token Category IDs](rationale.md#use-of-transaction-ids-as-token-category-ids) is derived from Bitauth's identity resolution strategy, and the [transferability of CashTokens' minting and mutable capabilities](rationale.md#behavior-of-minting-and-mutable-tokens) is derived from Bitauth's migration transactions (differing from earlier [colored coin](alternatives.md#colored-coins) proposals that associated capabilities with fixed public keys or contract hashes).

CashTokens offer some functionality similar to (and compatible with) Bitauth: Bitauth could be extended to allow the representation of identities with non-fungible tokens, reducing client validation requirements and preventing outdated wallets from inadvertently destroying Bitauth identities. While marking a particular identity with an NFT would negatively impact privacy (by reducing its anonymity set from all unspent outputs to only unspent outputs with compatible NFTs), the identity would also become usable with on-chain entities.
