Key Takeaways Sonic redesigns proof-of- stake to avoid Boneh–Lynn–Shacham aggregation, easing quantum upgrades. Shor’s algorithm risk pushes shift from Elliptic Curve Digital Signature Algorithm to hash-based schemes. Sonic Consensus System directed acyclic graph model could lead to reduction in upgrade costs, aiding post-quantum adoption. Quantum Threat Spurs New Approach to Blockchain Security As concerns grow over the long-term threat of quantum computing, blockchain developers are beginning to rethink the foundations of network security. Sonic, a proof-of- stake protocol, is positioning itself as one of the few systems designed to adapt more easily to a post-quantum world. Modern blockchains rely heavily …
