Abstract: Some embodiments described herein relate to a computer implemented method that includes performing a first work step associated with a first activity and with a first data product and performing a second work step associated with a second activity and associated with a second data product. A first chain of trust between the first work step and the second work step can be defined by defining a second manifest document that is associated with the second data product and that references a first manifest document associated with the first data product. An immutable data structure representing a second chain of trust independent of the first chain of trust can be defined by submitting the first manifest document and the second manifest document to a distributed ledger for validation.

Abstract: A federated-data-room server manages information about a collection of electronic documents residing elsewhere (under different organizational/customer control). The server can anchor documents to a blockchain, record usage history of each document, and provide access to the documents for authorized users. As a result, the federated-data-room server operates on customers' data, while leaving the data in control of the customers. At the same time, the federated-data-room server provides data access and enables traceability via blockchain recordation of document identifiers and document hash values.

Abstract: A computer system processes a digital representation of an illiquid asset, to confirm accuracy of the digital representation and value of the asset, and generates an asset-information table indicating where the various sections of the digital representation are stored. The system also generates an asset-value token, financial-return tokens, and a data structure that includes a self-executing program. The program associates the asset-value token with the financial-return tokens, so that the illiquid asset becomes a collateral for a decentralized loan transaction implemented using blockchain technology. The use of blockchain technology for decentralized loan transactions enables immutable data traceability.

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.
