A fragment and shuffle erasure coding operation is disclosed. In a transformative operation, encrypted fragments are generated from an input file. The transformative operation includes one or more iterations of chunking the file and mixing the chunks to generate a mixed sequence. The mixed sequence is sliced into encrypted fragments. The encrypted fragments are shuffled in a storage system such that physical locations of the encrypted fragments change over time.

Fragment and shuffle erasure coding technique

Techniques are disclosed for evaluating immutable ledger requests using a semantic taxonomy. An example system includes a memory comprising instructions, and a processor configured to execute the instructions. Example instructions include providing a semantic taxonomy of semantically linked terms and phrases; using the semantic taxonomy to validate input fields of requests for immutable ledger transactions according to one or more predefined templates; and submitting the validated requests to an immutable ledger.

Semantic-taxonomy-based immutable ledger request evaluation

Techniques described herein relate to a method for managing transactions in a distributed ledger. The method includes obtaining a transaction request from a client; in response to obtaining the transaction request: verifying client information associated with the client and the transaction request; anonymizing the transaction request to generate an anonymous transaction request; updating client payload mappings based on the anonymous transaction request; shuffling the anonymous transaction request with a batch of requests to generate a shuffle index; assigning the batch of requests to virtual users to generate virtual user assignments; and processing the transaction request using the batch of requests.
