One example method of operation may include extracting obligation data from one or more of documents and rules, identifying transaction data from one or more blockchain transactions, creating one or more transaction contexts based on the transaction data, comparing the obligation data to the transaction data to identify whether the one or more transaction contexts are subject to the obligation data, and creating a notification including a current compliance status between the transaction contexts and the obligation data.

Abstract: A processor-implemented method for a secure processing environment for protecting sensitive information is provided. The processor-implemented method may include receiving encrypted data and routing the encrypted data to the secure processing environment. Then the encrypted data may be decrypted and fields containing sensitive information may be found. The method may also include obfuscating the sensitive information and returning, by the secure processing environment, the decrypted data and obfuscated data.

Abstract: An example operation may include one or more of executing a blockchain transaction which generates modifications to an asset, identifying a most recent version of the asset comprising most recent values of the asset before the blockchain transaction, generating a delta block for the executed blockchain transaction identifying differences between the modifications to the asset and the most recent version of the asset introduced by the blockchain transaction being executed while excluding unmodified values of the most recent version of the asset which are not modified by the executed blockchain transaction, and hashing the delta block to generate a hashed delta block and storing the hashed delta block on a distributed ledger.

Abstract: A system, method, and computer readable storage medium configured for storing encrypted data in a blockchain. To write additional data in a blockchain, a request is received at a computing node. The request is typically cryptographically signed by a user system to include a new transaction with additional data in the blockchain. The additional data is previously encrypted with an encryption key. A new block that records the new transaction with additional data in the blockchain is added. To read the additional data in a blockchain, a request is received at a computing node with a transaction identifier and a decryption key from a user system to access data journaled as part of the blockchain in the transaction database. The transaction database is searched using the identifier. In response, to finding the corresponding block in the blockchain, the data is decrypted using the decryption key.

Abstract: An example operation may include one or more of receiving a transaction request into at least one node of a blockchain network, the transaction request comprising one or more transaction parameters and one or more encryption keys, processing the transaction request to produce a transaction result, encrypting one or more parameters of the transaction result to produce an encrypted transaction result, storing the encrypted transaction result in a data block of the blockchain, and storing the one or more encryption keys in one or more key stores of the blockchain network.
