What it is
Hedera is a public distributed ledger using hashgraph consensus to deliver fast, low-fee transactions, smart contracts, and tokenization for enterprise and consumer use.
Technology & consensus
Hedera uses hashgraph consensus: nodes gossip transaction information about gossip (gossip-about-gossip) and reach agreement through virtual voting, achieving asynchronous Byzantine fault tolerance with finality in seconds and no mining or block proposals. Fees are tiny and denominated in USD; the codebase is now open source under the Linux Foundation's Hiero project.
Token utility
HBAR pays network transaction and smart-contract fees, is staked to secure the network with proof-of-stake weighting, and is used across Hedera Token Service assets and dApps.
Key risks & notes
The official PDF could not be opened directly during this pass; the summary is grounded in Hedera's official whitepaper content and documentation. Governance is council-led rather than fully permissionless, and the 50 billion HBAR supply releases over a long schedule, creating ongoing distribution pressure.
