Hashgraph

Hashgraph algorithm, developed by Leemon Baird, the co-founder, and CTO of Swirlds, is one of the most secure, responsive and powerful technology. Hashgraph is a distributed ledger and a consensus mechanism which depends on virtual voting algorithm combined with gossip protocol. It reduces the requirement of major computation power and massive energy consumption. It can process a huge number of transactions per second. Also, it can eliminate the ripple in finance application. It provides an advanced security solution for online transactions which develops trust among user.
According to Hashgraph’s website, it is claimed that Hashgraph has the following properties:
Fast: 250,000+ Transactions Per Second
Fair: Mathematically-Proven Fairness (via Consensus Time Stamping)
Secure: Bank-Grade Security (Asynchronous Byzantine Fault Tolerant)
A cursory read of these three properties suggests that Hashgraph may indeed be a game changer — — with 250,000+ transactions/second, it could solve the scalability issue facing most blockchains today.
