We use our own framework called ChainLocker that reimagines the way modern users control their data.
ChainLocker enables its users to interact with each other directly by using private, permanent, bi-directional communication channels called lockers. Even Sequel, the maintainer of the platform, can’t access the data in users' lockers.
We tested it in the most demanding, regulated financial applications, and now we are bringing it to a broader audience. Every message, image and video goes to your permanent, personal data store, supported by a distributed ledger. Hence, it always remains yours, not just due to the recent advancements in data protection & privacy regulations, but by design.
