Permissioned blockchain on Hedera

Permissioned blockchains can use the Hedera Consensus Service, which delivers thousands of transactions per second with real-time finality in seconds.

Each Hedera network service uses hashgraph. Created by the founders of Hedera, the hashgraph consensus algorithm results in efficient, affordable, and environmentally friendly transactions.

Build on a reliable network backed by the Hedera Governing Council, a set of term-limited organizations that steward the codebase and direction of Hedera.

Each event logged with Hedera Consensus Service achieves consensus by the decentralized set of mainnet nodes, receiving an immutable and tamper-proof record.

Permissioned blockchains can log transaction hashes to the public ledger, presenting outside parties with the ability to recalculate and verify the integrity of information.

Hashgraph is asynchronous Byzantine fault tolerant (ABFT), offering the highest grade of security for any distributed ledger to make the Hedera network DDoS and Sybil attack resistant.
