🚴 Fiber Dev Log 31 🚴 This cycle was mostly about getting Fiber ready for v0.9.0. We shipped v0.9.0-rc3 and spent a lot of time on security hardening, bug bounty fixes, and an AI-assisted code review to help make the final release as solid as possible. Key updates: - Security fixes from bug bounty reports - AI-assisted code review across the codebase - Backup & Restore ready for the next release - Stronger validation for payments, routing, invoices, and gossip - Better tooling and operator UX Meanwhile, work continues on CCH, Atomic MPP, x402 payment proofs, backup/recovery tooling, and CLI/TUI improvements. By the way, the Nervos Bug Bounty program is always open. If you want to help us audit, identify, and report potential vulnerabilities, you can find the rules and rewards details here: bounty.nervos.org/ Shoutout to everyone testing, reviewing, and helping us catch those edge cases! 🙌 Full devlog: github.com/nervosnetwork/fib…

NIST published its final crypto agility guidance in December 2025. The message is clear: in the post-quantum era, systems must be able to change their cryptography without breaking. CKB was built for this from day one. While most blockchains are locked into protocol-level cryptographic assumptions, CKB is designed to adapt. That difference matters. Follow us over the coming days to learn why.

$CKB Blackbox Upgrades @NervosNetwork

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 🍻

Straight from @Coinbase’s April paper on quantum computing and blockchains. 👇 “Crypto-agility is a highly recommended practice in general [...] even more so in the context of PQC.” Now guess which chains were designed to switch cryptographic algorithms without disrupting operations🧠 Hint: there’s only one.

This is why **crypto agility** is super important for blockchains. It refers to "the ability to replace and adapt cryptographic algorithms for protocols, applications, software, hardware, and infrastructures without interrupting the flow of a running system to achieve resiliency." It's not a buzzword. It's a design imperative that @NIST keeps urging everyone to adopt. However, we don't see anyone else in the crypto industry approaching the threat of quantum computing with this in mind. CKB is the **only** crypto agile blockchain in existence. And it wasn't purpose-built for this. It's simply one of the features of its low-level flexible architecture. A bold design that is now paying dividends. Follow us to learn more about how CKB solved quantum resistance.

CKB Has No Plan — But We Do. Our previous posts about roadmaps generated some controversy. We’re grateful to have your attention. Because this distinction matters. CKB doesn’t have a roadmap because it is public infrastructure, not a product operated by a company. The goal of any serious blockchain is not endless reinvention. It is to become a stable, secure, and predictable infrastructure that others can build on for decades. That said, CKBA absolutely has plans. CKBA exists to coordinate stakeholders and grow the CKB ecosystem across the areas that matter most. That means organized work to attract builders, identify use cases, improve developer onboarding, fund ecosystem initiatives, pursue partnerships, clearly communicate CKB’s value, and actively engage the teams, companies, and communities that can drive real usage on the network. Having reorganized and unified several teams under a single structure puts us in a stronger position than ever to execute on these goals. A ton of work is already underway, especially on the Fiber front: improving the stack and documentation, advancing Lightning interoperability and liquidity management, and identifying and removing blockers for adoption. Work is also ongoing on the design and implementation of the DAO's on-chain treasury and voting mechanisms. And while there are many other initiatives in the pipeline that we’ll share when the time is right, there’s one that demands immediate attention 👇 Three months ago, Google Quantum AI published a bombshell paper showing that quantum attacks against secp256k1—the elliptic curve behind the signatures used by most blockchains—may require far fewer resources than previously estimated. In simple terms, the paper made the quantum threat to cryptocurrencies harder to ignore. The industry conversation that followed was, as expected, hard to miss — and yet it missed CKB. No mention in the paper, no mention in the con im versations on X and various forums, no mention anywhere. To put it bluntly, this is a huge communication failure on our part. CKB is the only cryptographically agile blockchain in existence, and therefore one of the few that’s already quantum ready. It’s the only chain where devs can bring new post-quantum signature schemes permissionlessly. No need for soft or hard forks. No need to pick a single PQ scheme and bake it in as a precompile. CKB is the only chain that can switch between different crypto primitives without disrupting operations or requiring significant infrastructure redesign. It’s the true embodiment of crypto-agility — yet barely anyone was aware of it. So, our first course of action on the communication front is to remedy that. We’ll run a comprehensive marketing campaign that’ll put CKB at the forefront of the Quantum x Blockchain discussion and position it as one of the few projects with a future-proof solution. And we want all of you involved. If you care about CKB and want to help push this forward, reach out. If you’re a developer, researcher, writer, designer, translator, community organizer, content creator, or just someone willing to help amplify the message, we want to hear from you. This campaign should not be about what CKBA has to say. It should be about making CKB impossible to ignore. We’ll be opening channels for community participation soon. In the meantime, reply here, DM us, or join the discussion on Nervos Talk.

In our last post, we covered the idea of a roadmap for CKB, and made clear that in many ways, the idea of a roadmap is antithetical to blockchains. Blockchains, if designed correctly, strive toward the opposite: ossification. For the uninitiated, ossification, in the blockchain context, refers to the process by which a protocol’s foundational rules become exceptionally resistant to change, ensuring ultimate stability, security, and predictability. It represents the maturation of a decentralized network from experimental technology to a rigid digital institution. A classic example of this from outside our industry would be the TCP/IP protocols that govern the internet. They have remained fundamentally unchanged for over 40 years. And that stability is precisely why the internet became what it is today. Because TCP/IP remained boring, predictable, and stable, billions of devices, applications, companies, and networks could coordinate around the same basic assumptions without asking anyone for permission. Email, streaming, messaging, cloud computing, social networks, and everything else evolved above the protocol—not because the base layer kept reinventing itself, but because it stopped changing enough for the world to build on top of it. That is the goal of public infrastructure: to remain simple, stable, predictable, and open and accessible. CKB is designed with this insight in mind: it remains conservative at the protocol layer, and optimizes for flexibility at the application layer.

🚴Fiber Dev Log 30🚴 Recent work has focused mainly on reliability, security hardening, and edge-case handling as we move toward the v0.9 release. That work is reflected in v0.9.0-rc2, including updates around migrations, funding persistence, parsing, routing behavior, and channel handling. We're also continuing review and polish work around trampoline routing, forwarding behavior, amount validation, browser integrations, and developer tooling/docs. This stage of the release cycle has focused more on improving behavior under failure cases and long-running operation than on introducing major new features.
