Researchers from several institutes worldwide recently developed Quarks, a new, decentralized messaging network based on blockchain technology. Their proposed system could overcome the limitations of most commonly used messaging platforms, allowing users to retain control over their personal data and other information they share online.
I’m not entirely convinced this needs a blockchain. I guess Hyperledger (Fabric, I’m assuming) is a handy way of guaranteeing a total order for a channel’s messages / events and making sure history is immutable, but it seems a bit unwieldy for a distributed messaging app despite being somewhat modular.
Most of their goals aren’t specifically dependent on anything blockchain-like, and the ones that are seem like they could be implemented in a much “cleaner” way than having to bring in Hyperledger and all that it involves
