BIP-47 reusable payment codes have long been on Bitcoin, but they're now implemented on Bitcoin Cash (BCH) and Litecoin (LTC): btc.com/btc/transactio… btc.com/bch/transactio… btc.com/ltc/transactio… #privacy

The @obpp_org and Justus Ranvier has released a RFC for version 3 of the Reusable Payment Code specification (known in Samourai as PayNym)! Big upgrades coming 🔥 github.com/justusranvier/…
