Hedera Hashgraph was originally a mathematical problem solved by Dr Leemon Baird. Dr Baird was an officer and professor at the US Air Force Academy. His partner Mance Harman was also an Officer and professor at the Air Force Academy. The American based platform was built and decentralized by adding a world class governing council. To my knowledge it is the only platform that has aBFT security. Launched in 2019, it has built a reputation of having the utmost integrity which is acknowledged by the names on the Governing Council. The partners that are building both on earth and in space (see Wisekey) creating a immutable accounting system for numerous use cases. Use cases have been highlighted by FedNow and a White house report. Additionally Swift has been testing for transfer use cases. This is a serious platform and investors would love to have access through ETF equity's. Thankyou for your attention in this matter.
