DAOism

For those of us shareholders in the DAO, I’m sure this will be a fun ride.. Guess which way we’re voting on the hard fork of the DAO… I do agree though that app security on the blockchain and off is not mature yet.

Supply Chain Blockchains

Washington University and BTC Media hosted the first blockchain forum dedicated to supply chain logistics and finance.
