Updated October 10, 2026. Rewritten with the actual timeline: the program was announced in August 2025, and live Chainlink data feeds reached 10 blockchains in 2026. Earlier versions described it as a formal “data-sharing arrangement” without dates or sources.
The U.S. government now publishes some of its most important economic statistics directly on public blockchains. It is a small program with a big symbolic meaning: official data that software on a blockchain can read and act on without a middleman. Here is what is being published, how it works and what it could be used for.
What happened
- August 28, 2025: the Department of Commerce announced it would publish economic data on-chain and selected two “oracle” networks, Chainlink and Pyth, to deliver it. Commerce Secretary Howard Lutnick said the goal was data that is more transparent and harder to tamper with. Pyth began by publishing quarterly GDP data, and a cryptographic fingerprint of the second-quarter GDP report was posted on several networks so anyone could check it had not been altered.
- 2026: Chainlink data feeds now deliver continuously updated values that smart contracts can use directly, on 10 blockchains: Ethereum, Arbitrum, Avalanche, Base, Botanix, Linea, Mantle, Optimism, Sonic and ZKsync.
What data is on-chain
Six data streams from the Bureau of Economic Analysis (BEA), covering three indicators:
- Real GDP: the level and the annualized quarterly growth rate
- PCE Price Index: the Federal Reserve’s preferred inflation measure, as a level and an annualized change
- Real final sales to private domestic purchasers: a measure of underlying demand that strips out government spending, trade and inventory swings
The feeds update on the same monthly or quarterly schedule as the regular government releases. The data itself is not new; what is new is the delivery channel.
What an oracle does
Blockchains cannot look things up on the internet by themselves. An oracle network gathers outside information, verifies it and posts it on-chain so smart contracts can use it. Chainlink is the largest such network and already supplies price data to many decentralized finance (DeFi) apps.
Why it could matter
With official data available to smart contracts, developers could build things like inflation-protected tokens that adjust automatically when the PCE index changes, prediction markets that settle on the official GDP figure, or lending products tied to economic conditions. As of September 2026, reporting found no live DeFi products wired to the Commerce feeds yet; these remain possibilities, not products.
There are also limits. Putting data on a blockchain proves it has not been changed after publication; it does not make the underlying statistics more accurate, and government data is still revised after its first release.
The bigger picture
The program fits a wider trend of traditional finance and government moving onto blockchain rails, from tokenized Treasury funds to tokenized stocks. For crypto, the significance is credibility: the federal government is treating public blockchains as a legitimate place to publish official information.
