Fixedproof

Fixedproof refers to a cryptographic technique used to ensure the integrity and authenticity of digital data. In essence, it allows for the verification that a piece of information has not been tampered with since a specific point in time. This is often achieved by creating a cryptographic hash of the data and then securely storing that hash in a timestamped and immutable ledger, such as a blockchain.

The process typically involves generating a unique digital fingerprint, or hash, of the document or data in question. This hash is extremely sensitive to any changes; even a minor alteration to the original data will result in a completely different hash. This hash is then recorded, along with a timestamp, on a distributed ledger. Because the ledger is decentralized and cryptographically secured, it is highly resistant to modification.

Anyone can later verify the integrity of the original data by recalculating its hash and comparing it to the hash stored on the ledger. If the hashes match, it provides strong evidence that the data has remained unchanged since it was first registered. Fixedproof is valuable in applications where proof of existence and non-alteration is crucial, such as in legal documents, intellectual property protection, and audit trails. It provides a robust and tamper-evident method for establishing the provenance and integrity of digital assets.
