Struct schnorrkel::derive::ChainCode [−][src]
We cannot assume the original public key is secret and additional
inputs might have low entropy, like i
in BIP32. As in BIP32,
chain codes fill this gap by being a high entropy secret shared
between public and private key holders. These are produced by
key derivations and can be incorporated into subsequence key
derivations.
