 headed.

   "About 40 years ago, Silvio Micali and his colleague Shafi Goldwasser
   wanted to figure out how to play poker together on their phones. They
   needed a way to ensure that neither could know the other player’s
   hands.

   The two computer science graduate students at the University of
   California-Berkeley drew up what Micali calls "the first secure
   encryption scheme the world has ever seen." For their invention, which
   proved vital to the modern internet, they were awarded the A.M. Turing
   Award, considered computing's equivalent of the Nobel Prize.

   Today, Micali, 67, is focused on another application of encryption: the
   blockchain, which is the foundation of bitcoin and other
   cryptocurrencies. At the Milken Institute Global Conference last week ,
   the MIT professor promoted [2]Algorand, a blockchain he developed that
   he says is greener, faster and more secure than other protocols.

   Blockchains are typically described as public ledgers where
   transactions are recorded on an open network. Validating a set of
   transactions to add to the ledger is one of the biggest security
   challenges. Algorand says it uses a novel approach involving the random
   selection of its users to ensure blocks of transactions are more
   resistant to hacks, which cost cryptocurrency holders a record $14
   billion last year by one tally."
