Recording Nasdaq Trades on Bitcoin Platform: How It Works | MIT Technology Review.
It’s much too early to tell whether Bitcoin is the future of money, but a recently launched Nasdaq experiment will test whether it can be the future of financial record keeping.
The stock exchange announced recently that it has begun experimenting with the blockchain—the publicly accessible and cryptographically verified record of every single Bitcoin transaction that has ever occurred. Transactions are verified and recorded in the blockchain by a network of “miners” all over the world who exchange their computing power for a chance to solve complex cryptographic puzzles and earn money—freshly minted bitcoins. Specifically, Nasdaq will take advantage of a feature in Bitcoin’s design that allows additional data to be recorded on the blockchain along with information about a Bitcoin transaction (see “Why Bitcoin Could Be Much More Than a Currency”).
