Data and security breaches are becoming increasingly common, highlighting the vulnerabilities of existing messaging and communications platforms. Devising computational tools and systems that better protect sensitive data against malicious attacks is therefore of utmost importance.

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.

    A ledger would prevent that change from happening, or at least leave a permanent record of the change

    Yes. That’s why most western land ownership systems moved to written ledgers in continuous, sequential books since, like, the slow collapse of feudalism 400-600 years ago. Let anyone add to the record but store those records in a way that they can’t be tampered with or removed after the fact, and let basically the entirety of the county’s land ownership records be tied up in one ledger that all land owners have an interest in properly preserving integrity.

    Basically, blockchain doesn’t actually help any more than simple/regular digitization does. Which already happened in most places 25-50 years ago.
