Unique, private, and yours.
What your PayNym can do for you
Each PayNym is unique
When claiming your PayNym from your Bitcoin wallet you are automatically assigned a unique name and Pepehash avatar. This gives an easy identifier for you to share with common contacts who you regularly transact with.
Your PayNym is private
When receiving directly to your PayNym or paying to another PayNym, you avoid having to share or request a Bitcoin address.
This makes PayNyms a great option to receive donations, and accept payment from / spend to regular contacts. Your PayNym is also used as a wallet identifier to coordinate or collaborate in peer-to-peer coinjoin transactions such as Stowaway and STONEWALLx2 via Soroban; the encrypted Tor based communication protocol.
Your PayNym is yours
As your PayNym is derived from your Bitcoin wallet's BIP47 reusable payment code, those in control of the wallet's private keys may use it as an authentication method to cryptographically sign in to applications and services using a challenge-response mechanism known as "AUTH47" (similar to how a Yubikey may be used to prove your identity when logging into your password manager).
