Consensus Service

Summary

With the Hedera Consensus Service (HCS), you can develop applications like stock markets, audit logs, stablecoins, or new network services that require high throughput and decentralized trust. This is made possible by having direct access to the native speed, security, and fair ordering guarantees of the Hashgraph consensus algorithm, with the full trust of the Hedera ledger.

In short, HCS offers the validity of the order of events and transparency into the history of events without requiring a persistent history of transactions. To achieve this, Mirror nodes store all transaction data so you can retrieve it to audit events.
