The ByteVault post-quantum hardware wallet implements Post-Quantum Cryptography (PQC) algorithm standards and combines NFC post-quantum communication with an on-chip signing architecture, thereby truly embedding post-quantum security into the transaction chain of the hardware wallet.

Future competition will not merely be about features, but about who can be the first to establish a truly usable quantum-secure infrastructure.

As the development of quantum computing continues to accelerate, an increasing number of mainstream projects are beginning to address the issue of “post-quantum security.” Now, Zcash has officially proposed a quantum-recoverable wallet and a comprehensive post-quantum upgrade roadmap, signaling that the industry is moving from the “discussion phase” to the “actual deployment phase.” The U.S. technology company ChainX Global Technology LTD has taken the lead in R&D: its ByteVault post-quantum hardware wallet has implemented Post-Quantum Cryptography (PQC) algorithm standards and, by combining NFC post-quantum communication with an on-chip signing architecture, has truly embedded post-quantum security into the transaction chain of hardware wallets. Meanwhile, ChainX Vault, as the application layer, synergizes with the ByteVault hardware system based on user scenarios, further establishing a closed-loop post-quantum security ecosystem spanning asset storage, transaction signing, and on-chain interactions. Unlike traditional solutions that “only support upgrades” or remain at the theoretical level, ByteVault has chosen to directly integrate PQC mechanisms into the hardware wallet signing process: • Enables secure interaction between the device and the application through an NFC communication architecture • Ensures private keys remain isolated within a secure hardware environment via on-chip signing • Applies Post-Quantum Cryptography (PQC) directly to the actual transaction signing process Future competition will not merely be about features, but about who can be the first to establish a truly usable quantum-secure infrastructure.

While the industry is still in the research and roadmap planning stage, ByteVault has already completed the practical integration of post-quantum cryptography (PQC) algorithms and implemented a quantum-resistant signature system at the product level, building a future-oriented security architecture.

[Quantum Computing on the Horizon: Is the Crypto World Entering the “Post-Quantum Security Era”?] Recently, the impact of quantum computing on the security of crypto assets has once again become a focal point in the industry. Research from Google Quantum AI indicates that, under specific conditions, future quantum computers could potentially derive a Bitcoin private key in approximately 9 minutes using an optimized version of Shor’s Algorithm—a timeframe that is approaching Bitcoin’s average block generation time. This means that an issue once considered “a long-term concern” is gradually becoming a reality in current discussions. Industry Consensus: Upgrades Are Possible, but Challenges Are Real Changpeng Zhao believes that the crypto ecosystem can address these challenges by upgrading to “post-quantum cryptography,” so there is no need for panic. However, the reality is: Upgrading decentralized networks is extremely difficult The technical path may trigger forks Existing assets and dormant addresses are difficult to upgrade simultaneously Uncertainties persist during the initial phase of new algorithms 👉 The direction is clear, but the window of opportunity is narrowing. From “Discussion” to “Implementation”: Security Systems Are Being Proactively Enhanced Against this backdrop, ChainX Global offers a more engineering-oriented perspective: Cryptographic security cannot wait until risks materialize to be upgraded; instead, the “post-quantum environment” must be considered at the underlying architectural stage. This has also driven some products to adopt more long-term security designs. ByteVault: The Technical Architecture Behind Quantum Resistance Unlike traditional hardware wallets that emphasize only “private key isolation,” ByteVault incorporates a more comprehensive security framework into its design. Its “quantum resistance” is not merely a concept but is built upon a concrete technical architecture: 1️⃣ Quantum-Secure Foundational Capabilities Chip-level secure operating system (COS) Supports the integration of quantum cryptography algorithms and blockchain-related algorithms Provides foundational support for decentralized identity authentication and asset security 👉 This means: It possesses the foundational capabilities to evolve toward a post-quantum cryptographic system 2️⃣ Hardware-Level Encryption System Based on the ARM 32-bit secure CPU architecture Integrated hardware encryption processor Supports multiple algorithm families: Symmetric Algorithms: TDES, AES, SM1, SM4 Asymmetric Algorithms: RSA, SM2, ECC Hash Algorithms: SHA-1 / SHA-256 / SM3 Also equipped with: High-Performance True Random Number Generator (TRNG) Multi-Sensor Protection (Voltage / Frequency / Temperature / Light Detection) 👉 Ensures high security and unpredictability in key generation and computation processes 3️⃣ High-level security protection mechanisms Utilizes EAL6 certified security chips Supports offline cold storage and multi-signature mechanisms Built-in: Storage encryption Address scrambling Data integrity verification mechanisms And features physical attack protection capabilities: Resistant to SPA / DPA / DEMA / DFA attacks Storage Level: EEPROM supports over 500,000 erase/write cycles Data can be retained for up to approximately 25 years (under specific conditions) Private keys never touch the internet 👉 A multi-dimensional protection system spanning from the physical layer to the algorithmic layer Key Insights into Quantum Resistance Based on the above architecture, ByteVault’s positioning can be understood as follows: 👉 Not a “simple hardware wallet” 👉 But rather a secure device system that has incorporated quantum-resistant design principles It already has the capability to support multiple algorithm systems (fast/non-convenient/hashing). At the architecture level, it can integrate and extend the PQC (Post-Quantum Cryptography) algorithm. A scalable security architecture Potential attack vectors from quantum computing have already been addressed at this stage From Device to Application: Building a Comprehensive Security Ecosystem Beyond the device, the ChainXVault application within its ecosystem is evolving in tandem: Support for asset management and interaction Mechanisms in place for future key upgrades Lowering barriers to user migration and adoption 👉 Gradually forming: A holistic security framework combining hardware and applications In Closing Quantum computing won’t breach the world of cryptography overnight, but it is changing one thing: Security no longer belongs solely to the “present”—it now belongs to the “future timeline.” Just as Satoshi Nakamoto’s original design philosophy for Bitcoin demonstrated: Systems can evolve, but security must be designed in advance.@cz_binance @Cointelegraph @VitalikButerin

量子威胁升级：Google研究称9分钟可破解比特币 odaily.news/zh-CN/newsflash/… via @OdailyChina

Google says a quantum computer could crack Bitcoin in 9 minutes. That’s faster than a block time. ⚠️ Crypto security is no longer “future risk” — it’s a countdown. 🔐 ByteVault is already live with post-quantum protection

Saw some people panicking or asking about quantum computing's impact on crypto. At a high level, all crypto has to do is to upgrade to Quantum-Resistant (Post-Quantum) Algorithms. So, no need to panic. 😂 In practice, there are some execution considerations. It's hard to organize upgrades in a decentralized world. There will likely be many debates on which algorithm(s) to use, resulting in some forks. And some dead project may not upgrade at all. Might be a good to cleanse out those projects anyway. New code may introduce other bugs or security issues in the short term. People who self custody will have to migrate their coins to new wallets. This brings to the question of Satoshi's bitcoins. If those coins move, then it means he/she is still around, which is interesting to know. If they don't move (in a certain period of time), it might be better to lock (or effectively burn) those addresses so that they don't go to the first hacker who cracks it. There is also the difficulty of identifying all his addresses, and not confuse with some old hodlers. Anyway, it's a different topic for later. Fundamentally: It's always easier to encrypt than decrypt. More computing power is always good. Crypto will stay, post quantum.

CZ @cz_binance ：加密总是比解密更容易 💬CZ 在 X 平台发文表示：看到有些人对量子计算对加密货币的影响感到恐慌或提出疑问。 从高层逻辑来看，加密货币需要做的只是升级到抗量子（后量子）算法。所以，没必要恐慌。😂 在实际操作中，有一些执行层面的考量：在去中心化的世界里，组织升级是很困难的。关于使用哪种算法可能会产生很多争论，从而导致一些分叉。 而且，一些已经“死掉”的项目可能根本不会升级。无论如何，清理掉这些项目也许是件好事。 新代码在短期内可能会引入其他漏洞（bug）或安全问题。 进行自我托管（私钥自持）的人将不得不把他们的代币迁移到新钱包。 这就引出了关于中本聪的比特币的问题。如果那些代币移动了，那就意味着他/她还活着，这会很有趣。如果它们（在一段特定时间内）没有移动，那么最好锁定（或等同于销毁）这些地址，以免它们落入第一个破解它们的黑客手中。此外，识别他所有的地址也存在困难，而且不能与一些老牌持有者（HODLers）混淆。总之，那是以后再谈的另一个话题了。 从根本上说： 加密总是比解密更容易。 更强大的算力总是好事。 加密货币在后量子时代依然会存在。
