logic: supports sensitive data encryption, esp. for CRUD operations (Create, Read, Update, Delete) over data submitted to or coming from the back-end. It also offers hash generation to unambiguously identify the PDF/A generated from the multisignature address, the transaction amount, and other metadata.

Core. The encrypted data from a drawer-signed DigiBoE triggers the execution of a smart contract that in turn generates and stores a multisignature address from the public addresses and keys of the involved parties. It simultaneously emits the legal document for verification by the drawee; the drawee’s authorization validates the now legally binding document which, together with its hash, triggers an update to the record with the multisignature address, gets encrypted, stored in the database, and an acknowledgment notice is sent to the recipient. The document’s hash and the multisignature address are permanently stored on the semantic blockchain as immutable proof of the event.

Back-End. Comprehends all CRUD functionalities with the database and storage (both fully encrypted) in such a way to support the rest of the process.
