user32570: The bitcoin-explorer command bx fetch-header -t 1 fetches the first Bitcoin block and shows the block header.
If I check the "first" block header, where does "previous block hash" come from?


user32570: Found the solution, the command for the genesis block should be:
bx fetch-header -t 0
