In Satoshi's paper, it says:
"The receiver generates a new key pair and gives the public key to the sender shortly before
signing. This prevents the sender from preparing a chain of blocks ahead of time by working on
it continuously until he is lucky enough to get far enough ahead, then executing the transaction at
that moment."
But the sender doesn't need the receiver's public key to prepare the blocks. So why this could prevent the sender from preparing a chain of blocks ahead of time?
Is I miss something? Please explain it to me, thanks~
If this can't work, what could prevent the sender from preparing a chain of blocks ahead of time?
