The Department published an official hash of its quarterly GDP data release for 2025—and, in some cases, the topline GDP number—to the following nine blockchains: Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism. The data was also further disseminated through coordination with the oracles, Pyth and Chainlink. The exchanges, Coinbase, Gemini, and Kraken, helped facilitate the Department’s publishing. The Department will continue to innovate and broaden the scope of publishing future datasets like GDP to include the use of other blockchains, oracles, and exchanges.
