(p. A9) Blockchains are basically a much better way of managing information. They are distributed ledgers, run on multiple computers all over the world, for recording transactions in a way that is fast, limitless, secure and transparent. There is no central database overseen by a single institution responsible for auditing and recording what goes on. If you and I were to engage in a transaction, it would be executed, settled and recorded on the blockchain and evident for all to see, yet encrypted so as to be villain-proof. “The new platform enables a reconciliation of digital records regarding just about everything in real time,” write the Tapscotts. No more waiting for that check to clear. It would all be done and recorded for eternity before you know it.
The digital currency bitcoin is currently the best-known blockchain technology. If I wanted to pay you using bitcoin, I would start with a bitcoin wallet on my computer or phone and buy bitcoins using dollars. I would then send you a message identifying the bitcoin I would like to send you and sign the transaction using a private key. The heavily encrypted reassignment of the bitcoin to your wallet is recorded and verified in the bitcoin ledger for all to see, and they are now yours to spend. The transaction is likely more secure and cheaper than a traditional bank transfer.

The layman, . . . , might want to wait for a more penetrable explanation of blockchains to come along–as one surely will if the authors’ predictions are even one-zillionth right.
