The public LEDGER is stored on mainnet nodes, initially run by the Hedera Governing Council — the governing council today includes companies such as Google, IBM, Boeing, Deutsche Telekom, LG, and more. In the future, mainnet nodes will be permissionless and run by anyone without informing Hedera.
Hedera network services are a set of APIs that allow developers to build decentralized applications. Each API call has an associated transaction fee based on the processing and storage required. As of 2020, there are over lications deployed on the mainnet, performing over 1.4 million transactions per day (October 2020).
Hedera also offers integrations for blockchain frameworks, such as Hyperledger Fabric and R3 Corda, which combine a private network’s privacy with a public network’s trust. By connecting permissioned blockchain frameworks to Hedera Hashgraph, private applications can offer public verifiability and decentralized ordering of transactions.
