People | Who is Adam Back?
Hashcash was originally designed to combat spam and denial-of-service attacks: the sender first had to solve a hash puzzle.
The key property of proof of work is that it is “hard to compute but easy to verify”: finding a hash that meets the requirements takes many attempts, while verification requires only one calculation.
The mining mechanism of $BTC draws on Adam Back’s Hashcash concept. Currently: 81750.05.
Don’t stake all your funds on a single judgment.
