*Added in protocol version 70211 of Dash Core as described by DIP3*
Masternode Provider - Update Registrar
The Masternode Provider Update Registrar (ProUpRegTx) special transaction is used
by a masternode owner to update masternode metadata (e.g. operator/voting key
details or the payout script).
A ProUpRegTx is created and sent using the `protx update_registrar` RPC.
The special transaction type is 3 and the extra payload consists of the following
data:
| Bytes | Name | Data type | Description |
| ---------- | ----------- | -------- | -------- |
| 2 | version | uint_16 | Provider update registrar transaction version number. Currently set to 1.
| 32 | proTXHash | uint256 | The hash of the initial ProRegTx
| 2 | mode | uint_16 | Masternode mode. Default set to 0.
| 48 | PubKeyOperator | CBLSPublicKey | The BLS public key used for operational related signing (network messages, ProTx updates)
| 20 | KeyIdVoting | CKeyID | The public key hash used for voting.
| 1-9 | scriptPayoutSize | compactSize uint | Size of the Payee Script.
| Variable | scriptPayout | Script | Payee script (p2pkh/p2sh)
| 32 | inputsHash | uint256 | Hash of all the outpoints of the transaction inputs
| 1-9 | payloadSigSize |compactSize uint | Size of the Signature
| Variable | payloadSig | vector | Signature of the hash of the ProTx fields. Signed with the key corresponding to the collateral outpoint in case the collateral is not part of the ProRegTx itself, empty otherwise.
The following annotated hexdump shows a ProUpRegTx transaction referencing an
existing collateral. (Parts of the classical transaction section have been omitted.)
