File timestamping: Network dependencies for issuing vs. verification

By PulseAugur Editorial · [1 sources] ·

This post explores the network dependencies involved in file timestamping and verification, distinguishing between the issuing and verification phases. During the issuing phase, a file's hash is sent to a service like ProofLedger to be batched into a Merkle tree and anchored to a blockchain, which requires network access. However, the hash itself, not the file, is transmitted, and its privacy depends on the content's guessability. The verification phase, conversely, is purely computational, involving recomputing hashes and Merkle paths locally. The critical dependency for verification is accessing the anchored root hash, which can be obtained from various sources including a self-hosted node, rather than relying on the issuer's service. AI

    What crosses the network when you timestamp a file, and how to check it yourself

    <p>Here's the question worth asking about your own provenance setup before any of the fun parts: at verification time, what has to be up?</p> <p>Not at build time. At verification time. Months from now, when someone asks you to prove a file existed on the date you say it did, whi…
