Hedera

Hedera Hashgraph is a distributed ledger technology that offers a new way of reaching consensus in a distributed system. Unlike other ledger technologies, Hedera Hashgraph doesn't rely on a single central authority. Instead, it uses a directed acyclic graph (DAG) to reach consensus. This makes Hedera Hashgraph more resilient to attacks and provides a more democratic way of reaching consensus.

Hedera Hashgraph can be used to build a variety of applications, including cryptocurrency, smart contracts, and file storage. The Hedera Hashgraph platform is built on three pillars: fairness, security, and stability.
