This made Hedera the first Layer 1 public distributed ledger to transfer its code to an independent, vendor-neutral governance body.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal \">The Hedera public ledger now operates as an instance of the Hiero codebase. By transferring ownership to LF Decentralized Trust, Hedera ensures the code remains open and independent, free from reliance on any single entity for maintenance or direction. This move integrates Hedera into a broader ecosystem of over 71,000 developers collaborating across more than 1,300 Linux Foundation projects globally.<\/p>\n<h3 class=\"font-claude-response-heading text-text-100 mt-1 -mb-0.5\">What Hiero includes<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal \">Hiero encompasses the complete technology stack that powers the Hedera network:<\/p>\n<ul class=\"[&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc space-y-2.5 pl-7\">\n<li class=\"whitespace-normal break-words\"><strong>Consensus Nodes<\/strong>: Manage transactions, token issuance, and smart contracts using the hashgraph consensus algorithm<\/li>\n<li class=\"whitespace-normal break-words\"><strong>Mirror Nodes<\/strong>: Provide historical data, analytics, and API access for auditing and application development<\/li>\n<li class=\"whitespace-normal break-words\"><strong>SDKs<\/strong>: Development kits for JavaScript, Java, Go, and other languages<\/li>\n<li class=\"whitespace-normal break-words\"><strong>Developer Tools<\/strong>: CLI tools, wallets, explorers, and testing frameworks<\/li>\n<\/ul>\n<p class=\"font-claude-response-body break-words whitespace-normal \">All components are available under the <strong>Apache 2.0 license<\/strong>, allowing developers, enterprises, and researchers to use, modify, and distribute the code freely.<\/p>\n<h3 class=\"font-claude-response-heading text-text-100 mt-1 -mb-0.5\">Community and contribution model<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal \">According to the 2024 Bitergia Radar Report, Hedera&#8217;s ecosystem included over <strong>655 contributors<\/strong> during 2024. Development follows a distributed model, with significant contributions from Hashgraph, LimeChain, and Envision Blockchain Solutions, alongside a growing independent developer community.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal \">The report notes that while company contributors focus primarily on core development\u2014the Consensus Node and Ledger\u2014the <strong>Tooling and Applications layers attract the majority of new contributors<\/strong>, indicating strong opportunities for community growth. Hundreds of thousands of lines of code have been produced by contributors not affiliated with Hashgraph, particularly outside the core platform components.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal \">Hiero adopts the Linux Foundation&#8217;s transparent contribution model. Anyone\u2014whether an independent developer or a major enterprise\u2014can contribute to the codebase, participate in Technical Steering Committee (TSC) meetings, and propose new features through a community-driven process modeled after Hedera&#8217;s HIP (Hedera Improvement Proposal) repository.<\/p>\n<h3 class=\"font-claude-response-heading text-text-100 mt-1 -mb-0.5\">Audits and verification<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal \">The hashgraph consensus platform code has been audited by multiple independent firms to ensure security and correctness. These include:<\/p>\n<ul class=\"[&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc space-y-2.5 pl-7\">\n<li class=\"whitespace-normal break-words\"><strong>FP Complete<\/strong>: Code audit of the hashgraph consensus platform<\/li>\n<li class=\"whitespace-normal break-words\"><strong>Carnegie Mellon University<\/strong>: COQ formal verification proof<\/li>\n<\/ul>\n<p class=\"font-claude-response-body break-words whitespace-normal \">Audit reports and verification documentation are publicly available on the <a class=\"underline\" href=\"https:\/\/hedera.com\/audits-and-standards\">Audits and Standards<\/a> page.<\/p>\n<h3 class=\"font-claude-response-heading text-text-100 mt-1 -mb-0.5\">Getting involved<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal \">Developers can engage with the Hiero project in several ways:<\/p>\n<ul class=\"[&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc space-y-2.5 pl-7\">\n<li class=\"whitespace-normal break-words\"><strong>Contribute code<\/strong>: Submit pull requests to Hiero repositories on GitHub across sub-projects including Consensus Nodes, Mirror Nodes, and SDKs<\/li>\n<li class=\"whitespace-normal break-words\"><strong>Propose features<\/strong>: Use the community proposal process to suggest and vote on new capabilities<\/li>\n<li class=\"whitespace-normal break-words\"><strong>Join discussions<\/strong>: Participate in TSC meetings and community channels<\/li>\n<li class=\"whitespace-normal break-words\"><strong>Access documentation<\/strong>: All documentation is hosted on a neutral platform to ensure accessibility and alignment with open source standards<\/li>\n<\/ul>\n<p class=\"font-claude-response-body break-words whitespace-normal \">The Hedera Council continues to operate the mainnet, deploying monthly releases across previewnet, testnet, and mainnet environments.
