Two Canadian tech firms are developing secure Internet of Things (IoT) communications using blockchain technology. The Waterloo Record reports on the partnership between Waterloo-based Terepac Corp. and Toronto’s Nuco Inc. The two firms recently launched a platform to secure internet-connected IoT devices using blockchain. Blockchain technology, upon which Bitcoin was built, provides secure, tamper-proof communications and transactions. “Blockchain is expected to transform almost every institution and every company,” said Terepac CEO Ric Asselstine.
