Software for securely storing digital content using a distributed ledger. The software performs the following operations: (i) receiving identification information of an owner of a digital asset, metadata of the digital asset, a digital hash of the digital asset, and the digital asset; (ii) verifying authenticity of the owner based, at least in part, the received identification information; (iii) in response to verifying the authenticity of the owner, creating a watermarked version of the digital asset based on the identification information of the owner, the metadata of the digital asset, and the digital hash; and (iv) storing the digital asset and the watermarked version of the digital asset in a first distributed ledger.

Securely storing digital content using a distributed ledger

An example operation may include one or more of transmitting a copy of the master ledger when a developer joins a network, receiving proposed changes to the master ledger, and updating the master ledger at the branch hash.

Blockchain technique for agile software development framework

An example operation may include one or more of transmitting a copy of the master ledger, wherein the master ledger comprises a code and history, receiving one or more changes to the copy of the master ledger, updating the master ledger when a required smart contract code standard is met, and initiating a push of the updated master ledger to one or more developer branches to enforce synchronization across the one or more developer branches.

Software for preventing fraud in digital content licensing and distribution using a distributed ledger technology. The software performs the following operations: (i) receiving a request for a license of a digital asset, wherein a record of the digital asset is stored in a first distributed ledger; (ii) verifying a consensus for the request of the license of the digital asset; and (iii) responsive to verifying the consensus for the request of the license of the digital asset: storing a transaction settlement record in a second distributed ledger, creating a sharded copy of the digital asset including a plurality of shards of the digital asset, and storing at least one shard of the sharded copy of the digital asset in the second distributed ledger with sharding instructions for reconstructing the digital asset from the sharded copy.

Preventing fraud in digital content licensing and distribution using distributed ledgers

An example operation may include one or more of creating a child ledger for each new environment that is setup, updating a master ledger when a smart contract condition is met, and when the master ledger is updated, initiating deployment of an update to a plurality of managed environments.

Configuration drift prevention across multiple systems using blockchain

A managing computer receives a proposed outgoing message that has been created for proposed transmission to one or more recipients. The managing computer determines a respective tone associated with one or more respective parts of the proposed outgoing message, and determines a probable interpreted tone of the one or more respective parts as perceived by the one or more recipients. In response to determining a difference between the respective tone and the probable interpreted tone for the one or more respective parts of the proposed outgoing message, the managing computer changes the one or more respective parts of the proposed outgoing message in order to create a modified outgoing message, where the probable interpreted tone for the one or more recipients of the modified outgoing message matches a sender-intended tone for the modified outgoing message. The managing computer then transmits the modified outgoing message to the one or more recipients.
