Sonic, a proof-of- <span>stake<\/span> protocol, is positioning itself as one of the few systems designed to adapt more easily to a post-quantum world.<\/p>\n<p>Modern <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-blockchain\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">blockchains<\/a> rely heavily on elliptic-curve cryptography to secure transactions and validate network participants. These methods underpin widely used signature schemes such as Elliptic Curve Digital Signature Algorithm (ECDSA) and Ed25519. While effective today, they could become vulnerable if quantum computers reach sufficient scale.<\/p>\n<p>A machine capable of running Shor\u2019s algorithm could break these cryptographic assumptions, allowing attackers to derive <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-private-key\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">private keys<\/a> from public data and forge transactions. By contrast, hash-based functions remain largely resistant, making them central to next-generation security models.<\/p>\n<p>\u201cWhether sufficiently powerful quantum computers arrive tomorrow or in 50 years, the industry must be prepared,\u201d said Bernhard Scholz, Sonic\u2019s Chief Research Officer.<\/p>\n<p>The challenge lies not only in replacing cryptographic primitives but in how they are embedded within existing consensus systems. Many leading proof-of- <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-staking\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">stake<\/a> networks rely on signature aggregation techniques, such as Boneh\u2013Lynn\u2013Shacham (BLS) or threshold signatures, to compress validator votes into a single proof. These methods improve efficiency but depend on cryptographic assumptions that quantum computing could undermine.<\/p>\n<p>Replacing them is not straightforward. Post-quantum alternatives, including lattice-based and hash-based signatures, tend to be larger and more computationally intensive. They also lack efficient aggregation methods, which could significantly increase bandwidth and verification costs.<\/p>\n<p>This is where Sonic\u2019s <a href=\"https:\/\/blog.soniclabs.com\/sonics-road-to-quantum-resistance\/\" target=\"_blank\" rel=\"noopener noreferrer\">design<\/a> diverges. Its consensus protocol, known as SonicCS, avoids reliance on aggregated signatures. Instead, it uses a directed acyclic graph structure in which each event carries an individual signature, combined with hash references to prior events.<\/p>\n<p>The result is a system that depends on fewer cryptographic building blocks. Transitioning to quantum-resistant standards would involve swapping out signature schemes without altering the underlying consensus logic.<\/p>\n<p>Sonic\u2019s approach reflects a broader trend in <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-blockchain\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">blockchain<\/a> development: planning for risks that may still be years away. While practical quantum attacks remain theoretical, the cost of retrofitting large, live networks could be high.<\/p>\n<p> <!-- --> <\/p>\n<p>The company said it will continue to monitor developments in post-quantum cryptography, including work by standards bodies and research efforts linked to major ecosystems such as <a href=\"https:\/\/buy.bitcoin.com\/eth\/\" target=\"_blank\" rel=\"noopener noreferrer\">Ethereum<\/a>.<\/p>\n<p>For now, the debate remains largely academic. But as digital assets become more embedded in financial systems, the resilience of their underlying infrastructure is drawing closer scrutiny. In that context, the ability to adapt without major disruption may prove as important as the security itself.<\/p>\n<\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/sonic-builds-quantum-ready-blockchain-with-simpler-architecture\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : Bitcoin News ) Key Takeaways Sonic redesigns proof-of- stake to avoid Boneh\u2013Lynn\u2013Shacham aggregation, easing quantum upgrades.
