US Government Posts Quarterly GDP Hashes on Nine Public Blockchains

The U.S. Department of Commerce is now publishing cryptographic hashes of quarterly GDP data on nine public blockchains, marking the first federal use of decentralized ledgers for key economic releases. By embedding official BEA figures on chains such as Ethereum testnet, the government ensures data immutability and transparency, reducing tampering risks and bolstering public trust. To cover transaction costs on these public blockchains, the department acquires crypto assets via major exchanges like Coinbase, Gemini and Kraken. This proof-of-concept reinforces the U.S. ambition to become the world’s blockchain capital and highlights real-world applications beyond finance. For crypto traders, the move signals growing institutional adoption of on-chain verification tools and may drive demand for network fees. While immediate trading volumes are unlikely to shift, the initiative points to long-term support for decentralized infrastructure and increased relevance of blockchain analytics in macroeconomic monitoring.
