Starting January 2026, the price for the ConsensusSubmitMessage transaction will increase from $0.0001 to $0.0008 USD. This change will take effect with the v0.69 mainnet release and applies only to ConsensusSubmitMessage transactions. This update improves the long-term economic sustainability of the Hedera network, while preserving predictable and USD-fixed pricing for developers.

Is hashgraph open-source? Is Hedera permissionless? Does the platform have smart contracts? Read this blog post to discover the answers to these questions and dispel some of the myths surrounding the world’s most used, sustainable, enterprise-grade public ledger.
- Myth #1: Hashgraph consensus and Hedera’s services are proprietary
- Hedera’s network services, officially supported SDKs, and every developer tool is open source under an Apache 2.0 license. Hashgraph consensus will be open source this year under an Apache 2.0 license. You can find the Hedera project’s GitHub here: https://github.com/hashgraph/
- Myth #2: Developers building dapps on Hedera can’t contribute to the project
- Hedera Improvement Proposals (HIPs) include core protocol changes, as well as changes to the applications, frameworks, and protocols built on top of the Hedera public network and used by the community.The goal of HIPs is to have a place for everyone to propose new features, collect community thoughts and input on a particular issue, document all subject matters in one place, and provide a status on their implementation. You can view all of the HIPs and contribute here: https://hips.hedera.com/all.html
- Myth #3: Hedera is a private, permissioned network for Enterprises
- The Hedera network is a public network infrastructure for everyone to anonymously create accounts and build decentralized applications on, without telling anyone who they are or performing KYC/AML.
- The Hedera network today is operated by members of the governing council — each of the 26 members independently operates and maintains an individual node in their own data center or public cloud, ensuring full decentralization of consensus. This year, Hedera is allowing for community nodes — any member of the Hedera community can independently operate a node and earn $HBAR. And in the future, the entire network will be permissionless.

- Myth #4: Hedera doesn’t have performant smart contracts
- Hedera’s smart contracts 2.0 is an implementation of the Besu EVM (Solidity) that has been optimized for the Hedera network and hashgraph consensus. Solidity-based smart contracts on Hedera offer the following benefits:
- No congestion fees for gas / all txn fees are fixed (www.hedera.com/fees)
- 15 million gas / second
- 300+ txns / second
- Integration with the native Token Service on Hedera mapped to ERC-20, 721, 1155 standards, 10k txns per second, and $0.0001 txn fees.
