Access Hedera networks and understand their nodes.
For every stage of development
From hello world to production, Hedera networks are available for each step of your journey. Get started on the Hedera testnet or previewnet for a free development environment and move to production on the Hedera mainnet, paying hbars for each transaction fee.
Start building on the testnet or previewnet with a Hedera profile.
Consensus nodes receive transactions, work together to determine consensus using hashgraph, and store the public ledger's latest state. The Hedera Governing Council currently runs all mainnet consensus nodes. As Hedera advances on its path to decentralization, anyone will be able run a consensus node.
Build validator networks on Hedera using scheduled transactions and multi-signature accounts to power use cases with greater programmability such as Decentralized Finance (DeFi) and cross-chain bridges.
