Hedera Hashgraph is distributed public ledger infrastructure. According to the team, it offers significant improvements over existing blockchains in five areas: performance, security, governance, stability, and regulatory compliance.
The project relies on Hashgraph, an asynchronous Byzantine Fault Tolerant (aBFT) algorithm, invented by CTO Dr. Leemon Baird, to achieve network consensus.
It features 10,000 TPS, transaction fee ~$0.0001, and a 3-5 second finality for confirmations.
The HBAR token is used for staking, as well as multiple services in the network.
