Distributed ledger technology can manifest in different forms and at Aqilliz, we’ve identified that a hybrid solution that combines the best of what both public and private blockchains have to offer, works best. Our underlying technological infrastructure, Atom, implements the best of privacy rendering techniques such as cryptography and differential privacy to allow brands to discover new audiences in the open web in a federated manner. Meanwhile, we’ve combined the security and scalability of a private blockchain with the accountability and decentralization of a public blockchain.
In accordance with data compliance laws such as GDPR, our solutions do not reveal raw individual data — instead, this remains in local storage (be it on user devices or servers owned by brands) before being anonymized and later being treated with differential privacy. Differential privacy masks individual data points with statistical noise in such a way that only aggregated insights can be revealed without any possibility of reverse-engineering the data set. Meanwhile, we’re also able to provide an independent and immutable record of processing any and every activity between enterprises, fulfilling the GDPR’s clause for a Record of Processing Activities.
As you can say, distributed ledger technology is not a one-size-fits-all solution that can be used out of the box. If we use our work at Aqilliz as an example, distributed ledger technology needs to be supplemented with other enhancements to provide a holistic, privacy-compliant infrastructure.
