The Hedera Hashgraph platform provide an alternative to blockchain technology and other distributed consensus algorithms by using a fundamentally different technology with unique capabilities. According to co-founder and CEO Mance Harmon, the hashgraph algorithm solves the most common problems with blockchain technology regarding performance, cost, and security.
Both Harmon and co-founder Leemon Baird are deep technologists and Harmon taught cybersecurity at the US Air Force Academy where Baird was a professor of computer science. Together, they are improving security and efficiency in cyberspace by providing a new type of distributed consensus.
According to Harmon, Hedera Hashgraph has achieved the best possible bandwidth efficiency and security. In addition, the platform has minimized the time needed to reach agreements at practically zero cost per transaction.
