In four years, could you prove it existed today?\nMost people cannot. They email the file to themselves, or post it, or trust that nobody will ask. None of that survives a determined question.\nThis is a record of a small system that answers it, built over several weeks and running now. It costs nine dollars. The file never leaves your computer. And the date it fixes does not depend on anyone continuing to exist — including the people who built it.\n\nHow it works, in four sentences:\nYou drop a file onto a web page. Your own computer reduces it to a 64-character fingerprint — the file itself goes nowhere. That fingerprint is published, with a date, in a public register. Periodically the whole register is summarised into one number and written into the Ethereum blockchain, where no one can alter it.\nAfterwards, anyone holding your original file can recompute the fingerprint with a standard command and compare. If it matches, the file is unchanged and existed before that block. They do not have to ask us anything, and they do not have to believe us.\n\nThis work cites 2 file fingerprints recorded elsewhere. The SHA-256 values are listed in the Frozen Extract.","demi_core":{"core_statement":"Anchoring the UplitAU register means hashing its index bytes exactly as served and embedding that digest in a self-transfer transaction, enabling three independent verification levels without operator involvement.","propositions":"The digest is SHA-256 of the register index as literally served, with no canonicalisation step; one transaction covers the entire register so anchoring cost is constant rather than per-record. Verification proceeds across three levels: file against record, record against snapshot, and snapshot against chain, with the chain level surviving operator cessation.","constraints":"Re-serialising the JSON, however correctly, produces different bytes and a non-matching digest; a record registered after the last anchor remains uncovered until the next anchor is published.","mechanisms":"The anchor digest is embedded as hex input data in a zero-value self-transfer transaction, and its presence can be confirmed by checking that gas used exceeds the baseline 21,000 of a plain transfer by approximately 512 units for a 32-byte payload.","boundaries":"The anchoring logic described covers only the register index as a whole and does not address individual record anchoring; practical implementation obstacles such as the absence of a data field in MetaMask's mobile wallet and its browser extension hiding the hex data field by default are known costs not found in any specification."},"core_withheld":false,"core_publication_basis":"Payment made from a wallet.

The Conceptual Core is published because the registrant is UplitAU Pty Ltd registering its own work, and UplitAU knows the author independently of how the payment was made.
