Dash Provider Registration Special Transaction. +//! +//! The provider registration special transaction is used to register a masternode. +//!

The ProRegTx contains 2 public key IDs and one BLS public key, which represent 3 different +//! roles in the masternode and define update and voting rights. A "public key ID" refers to the +//! hash160 of an ECDSA public key. The keys are: +//! +//! KeyIdOwner (renamed to owner_key_hash): This is the public key ID of the masternode or +//! collateral owner. It is different than the key used in the collateral output. Only the owner +//! is allowed to issue ProUpRegTx transactions. +//! +//! PubKeyOperator (renamed to operator_public_key): This is the BLS public key of the masternode +//! operator. Only the operator is allowed to issue ProUpServTx transactions. The operator key is +//! also used while operating the masternode to sign masternode related P2P messages, quorum +//! related messages and governance trigger votes. Messages signed with this key are only valid +//! while the masternode is in the valid set. +//! +//! KeyIdVoting (renamed to voting_key_hash): This is the public key ID used for proposal voting. +//!
