ChainCatcher message, well-known Chainlink community contributor Zach Rynes posted on X stating: "It is highly unlikely that the U.S. government will unify the use of a single blockchain to cover all departments and agencies. Do you think the ledger requirements of the EPA and FDA are exactly the same as those of the DoD and DHS? Probably not.The U.S. government will ultimately use multiple private and public ledgers for various different purposes, such as enhancing spending transparency or automating manual processes. What is certain is:All these different public/private blockchain ledgers will need to be able to communicate and share data across agencies through cross-chain interoperability standards;Agencies need to be able to seamlessly connect their existing backend systems and infrastructure to the various public/private chains used by the government through an abstraction layer;Agencies using blockchain to automate manual processes will need access to external data resources to securely trigger smart contract functions using oracles.A unified platform is needed to meet all these off-chain data, cross-chain interoperability, and legacy system connection requirements."
