Get Mining Block
Get Mining Block
Requests a block to begin working on a PoW solution. This method is primarily meant to support mining pool operation, so that miners do not need to function as DLT nodes and can simply request work units from the pool controller or another designated DLT Node.
The function only returns the relevant block data required for computing the PoW solution.
Note: In a cooperative pool mining, the solution should incorporate the pool controller's wallet address, so that it can be successfully verified by the DLT network. The pool controller is responsible for further reward payouts based on miner participation or any other metric at the pool's discretion.
