Hedera (HBAR) is the most used, sustainable, enterprise-grade public network for the decentralized economy that allows individuals and businesses to create powerful decentralized applications (DApps). Hedera Hashgraph isn’t built on top of a conventional blockchain. Instead, it introduces a completely novel type of distributed ledger technology known as a Hashgraph. This technology allows it to improve upon many blockchain-based alternatives in several key areas, including speed, cost, and scalability.
