Sui will support both Quantum Secure Addresses and Programmable Quantum Vaults in 2026. 2 complementary standards & algorithms. 2 different purposes. 1 native. 1 smart-contract based. We can't afford to wait. A dedicated working group votes on Monday to finalise the cryptographic protocols. This decision wasn't made overnight. Over the past 2 years we've worked with leading cryptographers, top universities, regulators, custodians, exchanges, wallet vendors, HSM manufacturers, and infrastructure teams. The landscape has changed dramatically: - We (@Mysten_Labs) introduced the first backwards-compatible post-quantum migration for elliptic-curve accounts. A problem that was considered unsolvable. - Google accelerated the conversation around practical quantum computing, their announcement changed the perception everywhere. - The community uncovered multiple implementation pitfalls in PQ libraries. - Hybrid vs native PQ became a serious engineering and cryptography debate. - Remora Proxies, the new Sui-funded innovation made large PQ signatures far less of a scalability concern. - Sui introduced address aliases, allowing seamless migration without abandoning existing identities. - NIST officially published the FIPS quantum standards, after a few finalists algorithms were broken this decade. - glaldly, more chains and Web2 infra started planning their transition. - Quantum-safe ZK systems reached a level where they are becoming practical. Next week I'll personally share the final decisions, timelines, and more importantly the reasoning behind every choice. This isn't just about protecting Sui. Cryptography cannot afford to wait. The entire industry needs to migrate sooner rather than later. One of the best ways to defeat well-funded malicious actors, including emerging nation-state adversaries, is to suffocate their target set. If valuable systems stop presenting vulnerable cryptographic targets, many attacks simply stop being worth attempting, this might even delay quantum computing for attacks, and just focus on the real needs, improving artificial intelligence. The goal is not to react after quantum computers arrive, but to remove the incentive long before they do. For those asking about our evaluation process, this forked and evolved benchmark is one of the inputs we use when selecting post-quantum authenticators (SPOILER: we've already pushed verification performance beyond what's shown here). mahdi-mysten.github.io/nist-… SUI QUANTUM
