Ultimately, Brooks served as the comptroller less than a year, from May 2020 to January 2021. At the OCC, Brooks established a reputation as a crypto-currency-friendly regulator, earning the nickname "CryptoComptroller."
The next phase in the crypto mining process is to compile a list of all transactions, which is subsequently included in a new unconfirmed data block. It avoids “double spending” of any cryptocurrency and keeps a permanent and public record by adding their transaction to the blockchain, once the verification procedure is complete. The record is immutable, which means it can never be changed or corrupted.

The blockchain technology backing cryptocurrency is inherently secure, thanks to the decentralized — and public — nature of distributed ledger technology and the encryption process every transaction undergoes.
Billed as the mother of all cryptocurrencies, Bitcoin which is a decentralised digital currency was created by someone called Satoshi Nakamoto (possibly a pseudonym) in 2009. As with most cryptocurrencies, Bitcoin is without a central bank or single administrator that can be sent from user to user on the peer-to-peer Bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a Blockchain, according to IANS report.
