Just about every hash is a representation from the earlier document, which produces a sequence of encoded paperwork that can't be altered devoid of transforming the hash. Each individual document is stored on computers inside a network. This network of packages compares Every single doc with those they have stored and accepts them as valid based on the hashes they produce. If a document isn't going to create a hash That could be a match, that doc is turned down by the community.
