🚴Fiber Dev Log 29🚴 We're moving through the v0.9.0 release cycle, with Fiber v0.9.0-rc1 out. This brings together updates across routing, funding, transport, and overall stability. This release candidate also introduced a unified migration system, laying a clearer framework for future database and protocol upgrades. We also improved the Network Actor stability, with updates to keep channel actors alive across peer disconnects. Better observability is also now in place with the addition of debug and trace logs throughout the channel funding flow. Community feedback continues to be a big help! Input from the WASM testnet recently helped us catch and fix an invoice payment rejection case involving zero-balance channels. Thanks to the community member who reported it. Moving forward, our focus shifts more on security hardening and finalizing the x402 end-to-end flow. Full log: github.com/nervosnetwork/…

Happy to see Fiber Link move from engineering prototype to product-ready! It's now a fully deployable community tipping layer over CKB, allowing members to support each other without running their own nodes. Product overview: github.com/Keith-CY/fiber… Fiber-Pay v0.2.5 also keeps evolving—simpler connect flows, passkey support, new demos, and AI agent use cases. 🏗️ More community-led experiments on Fiber here in Pulse 05: fiber.world/blog/pulse/iss…

Call remote AI agents from your browser. P2P Decentralized. Passkey login. And settled instantly and trustlessly via Fiber. ⚡️🔐  Try it out: calling-agent-kappa.vercel.app This is a recent experiment by Retric, exploring what AI services could look like when agents are independently hosted, directly callable, and paid peer-to-peer. The current pay-per-call model keeps things simple as a fixed-fee entry point, as low as 0.1 CKB per call on the Fiber testnet. Further plan includes transitioning to a more granular, token-based pricing (metering input/output usage). And if you're curious about why and how this was built, here's the write-up: talk.nervos.org/t/a-paid-ai-ag… #fibernetwork #nervos #AgenticEconomy

Fiber is moving from protocol ideas to real applications. Retric's been one of the builders exploring that shift firsthand. If you're curious about how Fiber actually works for real-world apps, hit the link and ask away! reddit.com/r/NervosNetwor…

🚴 Fiber Dev Log 28 🚴 Sharing a few things we've been working through lately: - Expanded Connectivity: added official Docker image support, plus Onion & Socks5. Also introduced transport type filtering to the connect_peer RPC, giving nodes more control over how they connect. - x402 & Preimage Proofs: Fiber can now act as an x402 exact-payment backend. It verifies paid invoices and returns deterministic receipts via the RPC HTTP listener. - Unified Migration Design: framework is now done. This is a key prerequisite for v0.9.0 and should make future protocol + database upgrades much smoother. Right now we're shaping up v0.9.0 (bringing in that Migration Support) and working through CCH multi-asset swap implementation. Also, great catching up with everyone at #Bitcoin2026 — heading back now and keeping pushing toward v0.9.0. 🚴 Full dev log: github.com/nervosnetwork/…

Back at our small booth on Day 2 of #Bitcoin2026 Good to see more builders stopping by and chatting! Our friends from @Nervapes are still hanging out in the area—WAGMI!! 🦍🏴‍☠️ Dropping some more recent shots on site. 📸 #FiberNetwork #Nervos #BTC2026

@FiberDevs The Fiber Pirates were out Having fun with booths and networking ! @bitcoinr3negade @Meta_Owl @VictorICP_ #BitcoinConference #Vegas

Finally got a moment to post about Day 1 at #Bitcoin2026! 😅 Booth is small and a bit messy, but we've had the best time talking with everyone who stopped by! Our neighbor @Nervape sent over their mascot to steal the spotlight. 🏴‍☠️🦍 Huge thanks to everyone who came to see us today. If you're in Vegas, come to Booth K4 and say hi tomorrow! ⚡️ #nervos #bitcoin2026 #lightningnetowrk

🚴 Fiber Dev Log 27 🚴 In last sprint, we shipped Fiber v0.8.0. This release comes with some meaningful structural changes. We migrated from PeerId to Pubkey to make RPC handling more consistent, and split the cross-chain hub into its own standalone process. For improvements & fixes, we've been: - Hardening P2P stability with gossip protection (banning + rate limits). - Syncing on-chain settlement status back to off-chain state for better consistency. - Patching a few OOM issues and a UDT funding bug. Right now, the team is refactoring the network actor hot path to resolve bottlenecks. We're also mapping out multi-asset swaps and looking into how to bridge Fiber with AI agents—specifically researching x402 and native agent protocols. Full dev log: github.com/nervosnetwork/…

🌊The last two weeks brought a wave of new projects, with more builders stepping in to try things out (shout out to @NervosCatalyst for hosting the hackathon 🫡) Beyond the hackathon, projects keep evolving and shipping: - Fiber Checkout is live for web apps. - Fiber Link is now open for public testing - Fiber Audio Player brings pay-per-second audio to the browser - Fiber Pay: v0.2.1 makes AI payments even simpler Check out Pulse 03 to see the community innovations: fiber.world/blog/pulse/iss…

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.

🚴 Fiber Dev Log 26 🚴 We're moving toward the v0.8.0 release and have been working on: - Upstream Ractor Integration: Switched to the upstream Ractor implementation to keep things clean and standardized. - Privacy Boost: Onion + SOCKS5 routing is well underway - Stability & Protection: Improved gossip protocols and new inbound/reconnect protections to keep the network resilient against resource-heavy peers. We're also in research for agent payment flows and shared a deeper look into CCH (Cross-Chain Hub)—the bridge for atomic BTC ↔ CKB swaps: github.com/nervosnetwork/… We're moving from simple 1:1 swaps to a multi-asset future with P2P negotiation and LND-style swap acceptors. The CCH plan is open for discussion! Check out the full dev log: github.com/nervosnetwork/… @NervosNetwork

We've been working to lower the entry barrier for Fiber even further. Introducing Fiber Demo Startup — a complete local dev environment for the Fiber Network. One-click start. Hours of setup saved. Everything runs out of the box with Docker: - CKB Dev Chain - Bootnode - 3 Fiber nodes - Fund distribution tool Plus a built-in interactive demo app. Two modes included: - Quick Start (beginners): from P2P connection to your first payment in 3 steps - Control Panel (advanced): a sandbox to experiment and see how Fiber works under the hood Who it's for: - Learning Fiber - Building Fiber apps - Demoing Fiber features - Exploring CKB payment channels hands-on GitHub: github.com/HappySonnyDev/… Dev notes: talk.nervos.org/t/fiber-networ…
