Using Threshold Signature Schemes means that an agreed number of parties must collaborate to create and use the keys. This ensures no single party has control over the assets. Hokan was designed to leverage TSS, in order to keep accounts secure from fraudulent activity and the loss of private keys.
After a registration phase, in which agreed parties are involved in the creation of the public key and the associated address, signatories use their personal “private share” to sign a transaction. The transaction is only valid if at least n (the threshold) of m (the actors) have signed.
