Step 1: Register
To use MetroGnomo you need to procure a MetroID. This will be sent through to the email address you provide. To aid those concerned with anonymity, MetroGnomo will issue a new MetroID whenever an email address is provided regardless of whether the same address has previously been used. Alternatively, MetroIDs can be reused to ease the process of locating a user’s ledger entries. MetroGnomo privately records all the existing MetroIDs attached to each email address submitted. This information enables MetroGnomo to remind users of their existing MetroIDs by email.
Step 2: Timestamp
Once a user is issued with a MetroID, this can be used to generate a timestamp – composed of an officially recorded time (called MetroTime), a unique universal identifier (UUID) and an optional description and file hash. Before an item is timestamped, a user must decide whether they wish the item to be publicly available (maximum size 10MB). The file will be saved in MetroGnomo’s publicly accessible central storage. Care should be taken as every timestamp is entered onto MetroGnomo’s transparent authoritative immutable ledger.
Step 3: View ledger
Each item’s timestamp is broadcast agnostically to all MetroGnomo’s receivers – whom hold MetroGnomo’s mutual distributed ledger. Users can view MetroGnomo’s timestamp broadcasts ‘live’ online through the website’s “view live ledger” functionality.
Step 4: Find a document’s timestamp
MetroGnomo.com provides a utility which will hash your document using MetroGnomo’s hashing algorithm, match it to identical documents previously uploaded, and then provide the user with the document’s previous timestamps.
Step 5: Retrieve fileIf a user decides to save their file with MetroGnomo.com, it can be downloaded using the website’s “Retrieve file” tool providing the timestamp’s original MetroTime or UUID is known.
