For the first time ever, BIP32 hierarchical deterministic wallets can be used to self define, publish, and revoke a cryptographic identity. This identity can be used to generate one time signatures for every item signed, hence achieving unprecedented signature security.
How it works
The identity is defined as the public master key of any node in a bip32 tree. This pub key can be shared, published at will, for instance on social networks.
Every signature can be traced to the corresponding public master key without ever exposing the corresponding private master key.
