i compiled it but i dont know how to mine the genesis block.
can you help me?
The blockchain client must be configured to mine the Genesis block. Your blockchain client's configuration file for mining should include the algorithm, Coinbase address, difficulty target, and more ancillary settings. After configuring now start mining using the 'start mining' command or you can give the mining command through the user interface. After starting mining you need to monitor whether the correct blocks are being mined successfully. You can verify with Blockchain Explorer whether the Genesis block has been successfully added to the blockchain after it has been mined.
