Bitcoin and the SEC regulation
In the simplest terms, a Blockchain is what forms Bitcoin. A Blockchain is basically a public ledger that cuts out the middle-man who would generally record a transaction between parties. Instead, there are certain people in the world who are considered bitminers. These miners have thousands of dollars in equipment and computers that track the transactions of Bitcoin and publish them on a public site called Blockchain.info. These computers essentially use logarithms to keep track of the transactions being made with Bitcoin. This public “ledger” is more secure and open than our current system of money exchange.
