Abstract: Some embodiments described herein relate to a computer implemented method that includes receiving a token that includes a reference to a first encrypted archive recorded in a distributed ledger. The first encrypted archive can be decrypted using the token to retrieve a first manifest document, which can be associated with a first activity of the complex transaction. The first manifest document can identify a second encrypted archive. The second encrypted archive can be decrypted using the token to retrieve a second manifest document, which can be associated with a second activity of the complex transaction. The second manifest document can include a reference to a data product, which can be retrieved. A continuity of the complex transaction between the second activity and the first activity can be verified based on the data product.
