Price Update to ConsensusSubmitMessage in Consensus Service | January 2026

By Ed Marquez

Starting in January 2026, the price for the ConsensusSubmitMessage transaction on the Hedera network will increase from $0.0001 to $0.0008 USD. This change applies only to the ConsensusSubmitMessage operation used in the Consensus Service (HCS). All other transaction fees on the network remain unchanged.

The new price will take effect with the v0.69 release of the Hedera Services codebase, currently scheduled for January 2026, as part of the planned mainnet upgrade. This initial announcement is being made six months in advance to ensure developers and ecosystem participants have ample time to prepare.

Why It Matters

This is the first time Hedera Council has adjusted transaction pricing since open access in 2019, reflecting the measured and responsible approach to network governance. The price adjustment improves the long-term economic sustainability of the Hedera network by aligning the fee with the computational and infrastructure resources required to process each ConsensusSubmitMessage operation and by ensuring fair compensation to node operators.

The new pricing reflects a modest adjustment from previously underpriced levels, aligning better with actual infrastructure costs and benchmarking across the industry. This supports the broader vision of building a scalable, high-performance public network that can serve mission-critical applications for decades to come.

At $0.0008, ConsensusSubmitMessage remains among the most cost-effective options in the industry while maintaining Hedera’s reputation for predictable, fixed pricing, which is critical for developers and enterprises planning at scale. HCS and its ConsensusSubmitMessage operation continue to enable high-throughput, low-latency decentralized logging and notarization use cases with exceptional reliability and performance.

Next Steps for Developers

We encourage developers to review their projected usage and cost models and make any needed adjustments ahead of the January 2026 release.
