Tell me about Adam Back.
Hashcash was initially designed to combat spam and denial-of-service attacks: senders first had to solve a hash puzzle.
One point that's easy to overlook: Hashcash uses computational cost to deter mass sending, while Bitcoin uses a similar idea to decide who gets to produce a block, and also rewards miners.
Be especially cautious of cloud-mining products that promise steady returns; many are actually scams.
$BTC 's mining method draws on Adam Back's Hashcash approach. Current price: 77320.18.
