How to unlock the full potential of HCS (and why it is not a database)

Hedera Consensus Service (HCS) is clarified as an ordered, tamper-resistant event log—not a database. The piece emphasizes using HCS for provenance, ordering, and verification, while storing large data externally and using indexers to derive queryable state. It highlights architecture best practices: submit hashes or state transitions to HCS, rely on external databases for reads, and use Mirror Node REST API to build indexes. Notable update: January 2026 base ConsensusSubmitMessage fee rose to $0.0008. Practical guidance on scalable event-sourcing with HCS remains central.
