Hedera

Hedera is a public network built on hashgraph consensus rather than a blockchain, offering asynchronous Byzantine fault tolerance and a fixed supply of 50 billion HBAR. Its most distinctive feature is not technical but institutional: governance sits with a council of large organisations serving limited terms.

Gossip about gossip

Nodes share transactions with random peers and also share the history of who told them what. From that record each node can compute the ordering every other node would reach, without a separate voting round. Consensus is derived from communication that had to happen anyway, which is where the efficiency comes from.

Asynchronous BFT is the strongest guarantee available

Most networks assume messages arrive within some bound; asynchronous BFT makes no timing assumption at all and still guarantees agreement provided fewer than a third of nodes are malicious. It is a genuinely stronger property than most consensus protocols claim, and it is a real engineering distinction rather than a marketing one.

Council governance, stated plainly

Network nodes are run by council members — large enterprises and institutions across sectors and jurisdictions — each serving limited terms. This is more decentralised than one company and far less open than permissionless validation. Hedera does not present it otherwise, and evaluating the network means evaluating that council.

Predictable fees, fixed supply

Supply is capped at 50 billion HBAR with no further issuance beyond the release schedule, and fees are denominated in dollar terms so costs stay stable as the token's price moves. For enterprises budgeting transaction costs, predictable pricing matters more than low pricing.

Services rather than contracts alone

Alongside smart contracts, the network offers native services for token issuance, consensus timestamping and file storage. Enterprises frequently want an auditable ordered log rather than a full application, and exposing that directly avoids deploying a contract to do it.
