Coinbase Changes
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
Once v20 activates, Coinbase transactions in all mined blocks must be of version 3.
|
||
|
|
|
||
|
|
Version 3 of Coinbase will include the following two fields:
|
||
|
|
- bestCLHeightDiff (uint32)
|
||
|
|
- bestCLSignature (BLSSignature)
|
||
|
|
|
||
|
|
bestCLSignature will hold the best Chainlock signature known at the moment of mining.
|
||
|
|
bestCLHeightDiff is equal to the diff in heights from the mined block height to the actual Chainlocked block height.
|
||
|
|
|
||
|
|
Although miners are forced to include a version 3 Coinbase, the actual real-time best Chainlock signature isn't required as long as blocks contain a bestCLSignature equal to (or newer than) the previous block.
|
||
|
|
|
||
|
|
Note: Until the first bestCLSignature is included in a Coinbase once v20 activates, null bestCLSignature and bestCLHeightDiff values are perfectly valid.
