I have been hearing a lot about Blockchain recently. According to Wiki – Functionally, a blockchain can serve as “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.” Today’s needull is an example of Blockchain being used for social impact.
Kevin Werbach, a Wharton professor of legal studies and business ethics who has studied the blockchain, says there’s been an “explosion of blockchain-based applications and systems. It’s still very early. It’s still not as solid and reliable as where they need to be, but it is clearly where we’re going to see more activity.” He notes that the blockchain has been used in various social impact efforts. In May, the United Nation’s World Food Programme conducted a pilot that gave cryptocurrency vouchers to 10,000 Syrian refugees in Jordan that they redeemed at certain markets.
