How it works

Learn how hashgraph and Hedera network services work together for you to create an entirely new class of applications.

Hashgraph consensus

Hedera is the only public ledger that uses hashgraph consensus, a faster, more secure alternative to blockchain consensus mechanisms. Hashgraph works efficiently to verify transactions while ensuring the highest standard of security to prevent malicious attacks. Hashgraph achieves high-throughput with 10,000+ cryptocurrency transactions per second today and low-latency finality in seconds from its innovative gossip about gossip protocol and virtual voting. Once consensus is reached, the transaction is immutable and available on the public ledger for everyone to transparently see.

Public ledger


Hedera is a public ledger of transactions – a highly secure and distributed database that everyone can read from and write to.

A copy of the ledger, which only persists the latest state, is stored on each node. It's these core concepts of distributed consensus and decentralization that make public ledgers the most trusted way to store verifiable information and assets.

Network nodes


The public ledger is stored on the mainnet, a network comprised of consensus nodes. While currently permissioned, and run by the Hedera Governing Council, in the future consensus nodes will be permissionless – able to be run by anyone.


Consensus nodes come to consensus on the validity and order of transactions while storing the latest state of the network. Mirror nodes can be run by anyone and offer a flexible and cost-effective way to store and query historical data without a loss in trust.

Hedera network services

Hedera network services are a set of APIs that allow you to create accounts, mint tokens, write data to the ledger, and much more.

Each API call has a transaction fee based on the processing and storage required. Hedera SDKs make it easy to access the API in your favorite language.

Token Service

Configure, mint, and manage fungible and non-fungible tokens on Hedera without needing to set up and deploy a smart contract.

Decentralized applications

Applications that use a public ledger provide greater transparency and trust. This makes entirely new things possible, like a music streaming service paying artists directly or a disintermediated ad network that doesn't require audits. Collectively, these applications create network effects on Hedera to establish a more fair, secure, and decentralized future.
