Validator key management

A LEEQUID multisig guardian is entitled to a share of the validators' seed phrases used for the LEEQUID protocol. In each node, validators are generated with a different seedphrase.

Each of these seed phrases is split in 7 shares using the Shamir Secret Sharing algorithm, with a threshold of 4 shares required to recover the seed phrase.

Each of these 7 shares will be encrypted and sent to a different shareholder using their RSA key.
