@ThuanCapital Thuật toán mã hóa dựa trên hàm băm an toàn và ổn định hơn. HAWK hay mấy thuật toán Lattice thì phải trải qua những lần bị phá vỡ thế này mới trở nên ổn đinh được.

AI phát hiện lỗ hổng trong thuật toán chống lượng tử, Bitcoin chưa bị ảnh hưởng Anthropic cho biết AI của hãng vừa tìm ra cách phá vỡ một phần thuật toán mã hóa có tên HAWK, vốn được đề xuất để thay thế các phương pháp bảo mật hiện nay khi máy tính lượng tử ra đời. Việc này chỉ mất 60 giờ và khoảng 100.000 USD, dù thuật toán từng được nhiều chuyên gia kiểm tra suốt hai năm mà không phát hiện vấn đề. Kết quả là thuật toán này gần như mất đi lợi thế vốn có. Bitcoin và Ether hiện chưa bị ảnh hưởng vì dùng công nghệ bảo mật khác. Tuy nhiên, sự việc cho thấy các công cụ AI đang bẻ khóa mật mã nhanh hơn nhiều so với trước, khiến giới công nghệ càng phải gấp rút tìm giải pháp bảo mật chống lại máy tính lượng tử. Diễn biến này trùng thời điểm mạng Zcash vừa nâng cấp hệ thống để chuẩn bị cho tương lai đó.

@CoinMarketCap it's quantum safe

how is your wallet?

Are Bitcoin and Ethereum quantum resistant? Not today. Both networks authorize transactions with ECDSA over secp256k1, the signature scheme a sufficiently powerful quantum computer running Shor's algorithm could eventually break. More than 7 million BTC sit in addresses with public keys already visible onchain. Ethereum has an even broader exposure because users keep using the same account for years. Once an Ethereum account sends its first transaction, its public key can be recovered from the blockchain permanently. That means an attacker can harvest those public keys today and simply wait until quantum hardware is powerful enough to derive the corresponding private keys. Both ecosystems are preparing. Bitcoin has BIP 360 and BIP 361 on the table, with the replacement algorithm and migration framework still up for debate. Ethereum has a structured roadmap built around native account abstraction, targeting milestones through 2029. Under optimistic assumptions, either path takes years to complete. And that's only the first migration. Today’s post-quantum algorithms likely won't be the final ones blockchains adopt. As PQ cryptography evolves, blockchains will need to keep evolving with it. Which raises the deeper question: can a blockchain keep replacing its cryptography as the landscape shifts? The primitives being standardized now will age like every generation before them, and the systems that endure are the ones able to adapt each time it happens. That property has a name: crypto agility. The full breakdown, including where CKB fits, is here: nervos.org/knowledge-base…

The crypto industry has spent the past week telling the press it is preparing its defenses against quantum computing. The same coverage carries a warning from the same executives: moving early is dangerous, because post quantum cryptography is still evolving; move too late, and it’s game over. So the industry finds itself stuck between two risks. Wait too long and exposed keys pile up, the attack surface becomes massive, and the pressure to rush a migration at any cost balloons. Move too soon and you risk welding tomorrow's legacy algorithm into your consensus rules. That bind exists for one reason: on most blockchains, cryptography is hardcoded at the protocol layer, and changing it means a fork the entire ecosystem has to coordinate around. CKB was designed without that constraint. Signature verification lives in programmable Lock Scripts, which means anyone can deploy new signature schemes permissionlessly and without waiting for a network-wide consensus. A SPHINCS+ Lock Script has been live on mainnet since 2025. A self custodial quantum resistant wallet built on it shipped in February. If the standards ever move past SPHINCS+, a new PQ scheme can be deployed the same way: quickly and without technical or social disruptions.

Quantum risk is not the same for every crypto holder. The first thing that matters is exposure. If your public key has never appeared onchain, a future quantum attacker has nothing to work with. But once your public key is revealed, it becomes part of the permanent public record, and a future attacker can copy it today and wait indefinitely for quantum hardware to catch up to attack it. Therefore, preparing for Q-Day requires some forethought. You need to think about the level of your exposure and how to migrate your assets to a quantum-safe environment on time.

“Harvest now, decrypt later” is one of the most under-appreciated risks facing crypto today. The phrase usually describes an attack where an adversary collects protected data now and stores it, waiting for future technology that can break the cryptography protecting it. In crypto, the problem is simpler, as blockchains make the “harvest” part trivial. The data is already permanent, publicly visible, and therefore easy to archive.

Here's a fun little exercise for crypto bros: Open the quantumtracker.org website by the legends @tectonicxyz Select "Blockchains" in the sidebar. Sort by "Tier." Notice who sits at the top with the most green check marks :) Cheers 🍻

While the Fiber Dashboard shows you that Fiber is alive, Echo gives that quietness a pulse—letting you experience the network through motion, rhythm, and sound. 🎶😌 Vibe-coded by our UI designer (who also designed the Fiber Dashboard—and sings great karaoke😍), Echo is a visual and sonic take on network liveness. As for the name, an echo only exists when there's connection, response, something beyond yourself. That felt right for Fiber. A network only becomes alive when people join, connect, and interact.

We are excited to announce that QuantumPurse is expanding its scope with two new projects: 🚀 QuantumPurse V2 Building on the foundation of QuantumPurse V1, security is reimagined across every layer — from software to hardware. High-performance, feature-rich, and built natively for each platform. 🔐 Hardware Integration Building on the shoulders of Trezor, we’re integrating CKB and bringing quantum-safe crypto to the quantum-ready hardware wallet, Safe7.

Don’t you just hate it when you’re trying to install a light client on a handheld gaming device and it doesn’t have a new enough version of glibc? Then you gotta rewrite the #nervosnetwork light client to use musl and you might as well swap to SQLite while you’re there👀 #ckb

I had a goal today of making a easy to use remote light client installer over ssh. That got made in about 5 minutes and I got a little sick with it. #nervosnetwork Python ports app that automates a light client installation and easy persistent service toggle. #runckb

Last year was a big one for CKB!🎊 From the smooth activation of the Meepo hard fork to the launch of the first quantum-resistant wallet, we saw major technical milestones crossed while projects across the ecosystem continued to grow and ship📈 Dive into the full 2025 Annual Report to see everything that happened ↓ nervos.org/assets/pdfs/Ne…

@Charlie_Kong_B @SMQKEDQG @quantumpurse I read the conversation between the guy who did it for $700 and the promo. CKB tried to get me to do it too, in TG. I said no.

Interesting read 👀 When it comes to post-quantum security, smaller blockchains often move faster--lower systemic risk, tighter communities, and less technical debt. This piece highlights that 12 blockchains, including CKB, have already migrated or have concrete plans to migrate to specific post-quantum signature schemes. For CKB, quantum resistance isn't a marketing checkbox. It's an architectural question. 👌

We've been talking a lot about tech here — Scripts, VM, protocols, optimizations ... Love that! But builders aren't just commit histories. That's why we started CKB Builder Story, a small series about the people behind the protocols. 🧑‍💻✨ Our first story features Tea (@teaplusplus11), creator of Quantum Purse (@quantumpurse), the industry's first SPHINCS+-based quantum-resistant wallet. He has built across ecosystems: EOS, Bitcoin, Ethereum, and now CKB. Here he shares how he stumbled into CKB, why he decided to stay & build long-term, his appreciation for Proof of Work, and why good architecture + good people matter. #nervos #pow #BlockchainDev
