The ledger also shows the version history of a document and has a search function where different search criteria (e.g. document ID or checksums) can be used to search for, locate and display the available details about the document.
The ledger has an API where other services or applications can connect to the ledger to download the document or obtain metadata about a document that can be used to verify the document or a signature.
All documents published in the ledger are trackable, identifiable and verifiable.
