However, thinking about cryptocurrencies from the point of view of the Federal Reserve, or a senator on the Banking Committee, or a trader at a bank’s prop desk, cryptocurrencies such as bitcoin have a lot of advantages—they’re not something to be dismissed out of hand.
All of bitcoin’s benefits to the establishment revolve around its blockchain.
In simple terms, a blockchain is a registry of all transactions carried out in bitcoins. Thus is resolved the problem of double-spending one particular bitcoin: It can’t be done (at least in theory) due to the blockchain.
But the blockchain is in fact a register—a trail—of bitcoins. So it’s a relative cinch to piece together each and every transaction of any particular wallet in the bitcoin universe. And since exchanges need detailed personal information about a bitcoin user in order to comply with money-laundering laws before issuing a new user with a wallet, the government or other interested parties could determine what any one particular person has been doing in the bitcoin marketplace.
In other words: Imagine that the government knew each and every cent you earned and spent, without a single exception.
