2 Kings Chapter 12. The people wanted a more secure way to keep track of their funds following a security breach. So Jehoiada the priest created a wallet where the people could deposit funds, but no one would able to transfer those funds without the private key. The people who kept the ledger secure received payments for blocks.

But then shortly thereafter they changed from a proof of work model to a form of proof of stake, and eventually all the money ended up going to the priests. The people seemed to be okay with this.
