Back’s Hashcash paper grudgingly claimed its author "was not aware" of these prior works before unveiling his own creation. But PoW didn’t originate with Back.

Bitcoins too exist as digital records of obligations, physically encoded on servers of those who hold them, propagated and distributed for transparency and security, encrypted for privacy. What’s most fascinating about these new digital cryptocurrencies is how much they reveal about the surreal nature of currencies and wealth in our digitized economy. Bitcoins are as real as money in banks.

They are tangible, even though digital, and they record the debts owed among parties. Digital bank ledgers now track money without the necessity for physical transfers of currencies. While cyberspace is ephemeral, it is still real and physically based.

The beauty of bloom filters is that many patterns can be kind of etched onto the same area. This helps improve your privacy by not directly sending full node your data and also reduces the chance for full node to lie. Here comes bloom filters.

State insurance and the contractual guarantee that a bank will pay back what has been put into them mean that there is some force behind our trust in the continued existence of a person’s wealth while digitally stored in a bank’s servers. Depositors to banks are protected in their debts by states, generally, bitcoin and through contracts with their banks.
