RGB super-compatibility is not a promise but an engineering discipline enforced with zero tolerance for regression.
RGB on Lightning: Walking with Upstream
While the previous release proved that RGB could connect to Lightning through full LDK state machine compliance, 1,019 tests, and CLN/LND interoperability, the latest release now answers the harder question of whether RGB can evolve at Lightning's pace without friction — and it does.
We synced our upstream dependencies with the Lightning mainline, absorbing 16 medium-or-higher security fixes, including critical vulnerabilities that were never backported.
We’ve formalised this approach as bLIP-0070, encoding super-compatibility at the protocol layer via feature bits 826 (mandatory) and 827 (optional), along with TLV type 827167.
Compatibility only earns the right to the real work of making Lightning’s most advanced primitives asset-native: Splice support, already live in BTC channels, will extend to RGB channels for adjusting capacity without closing, while Async Payments and offline receipt of value will carry over to RGB assets, and JIT liquidity will follow—all without bridges, custodial wrappers, or separate networks, leaving simply the Lightning Network with RGB as its invisible programmable layer.
Compatibility is not pitched as a feature; it is shipped as infrastructure, making Bitcoin smart.

RGB Lightning Node v0.0.2 is now live.
Public repo:
This release introduces a fully redesigned control panel with meaningful improvements to both usability and protocol-level functionality.
Key updates:
— Wallet: Rebuilt Receive and Send flows with native support for RGB asset import/export. Transaction history now surfaces asset transfer metadata.
— Node Management: Connect and disconnect Lightning nodes directly from the UI. Open and close channels with streamlined UX.
— RLN Initialization: New node creation flow with clear visualization of local and remote node topology.
— RGB Asset Detail View: Extended metadata display with UTXO binding visibility for RGB assets — enabling users to inspect the on-chain anchoring of off-chain state.
We continue to build at the intersection of Lightning and client-side validated smart contracts. The infrastructure for tokenized assets over Bitcoin is not theoretical — it is shipping.

We have published the full engineering design behind native RGB Swaps on the Lightning Network.
The swap is not a separate protocol layered on top of Lightning — it is a property of the payment path itself. A single circular route, one payment_hash, zero external coordination. Atomicity is not enforced by an additional contract; it falls out naturally from Lightning's preimage settlement.
This design handles non-monotonic value flows across multi-asset channels, affects commitment construction, HTLC state management, and client-side transfer history at the architectural level.
The RGB Lightning Network has reached production-grade engineering. Large-scale testing begins now.

They said programmable Bitcoin on Lightning was years away. We built it today.
Introducing Bitlight RLN. We haven’t just built a client; we’ve unlocked the final form of the Lightning Network. For the first time in history, RGB asset issuance and transfer are seamlessly integrated into Lightning.
We are doing to Bitcoin assets what broadband did to the internet. Instant. Frictionless. Limitless.
Issue assets. Open channels. Transfer at the speed of light. Settle with Bitcoin's ultimate security.
The era of whitepapers and testnet illusions is over. The future of Bitcoin finance just shipped.
Witness the paradigm shift. Watch the walkthrough and try it on your own.

Bitlight Labs Technical Update – February 21, 2026
We are pleased to announce significant updates to our RGB Lightning Network (RLN) infrastructure and the release of a new developer sandbox.
1. RLN Node & CLI Enhancements
Repository:
We have refactored payment logic to a resource-oriented architecture. Key updates include:
- Expanded Payment Controls: Added specific subcommands for pay invoice, offer, refund, and keysend.
- BOLT12 Support: Integrated BOLT12 capabilities along with wait and abandon payment states in the API and TypeScript SDK.
- Documentation: Updated all examples and docs to reflect the new node topology.
2. New Developer Sandbox
Repository:
We have released a React + TypeScript web frontend for the Bitlight LN Hub to facilitate testing and development. Features include:
- RPC Proxy: A backend implementation (in src/app/api) to securely proxy RPC calls and resolve cross-domain restrictions.
- Dockerized Environment: Includes a pre-configured Bitcoin regtest container (bitcoind) with scripts for wallet creation and rln-ldk-node server initialization.
Developers are encouraged to review the repositories and update their local environments accordingly.

# 🚀 Sharing Our Team's Recent RGB Protocol Learnings
With the stellar documentation from
@aaronzhang and the dev environment built by the bitlightlabs team, we successfully validated the RGB v0.11 token transfer demo and gained a grasp of the protocol’s transfer mechanics.
Docs reference:
## 🧩 Current Problem
To date, no developer has rolled out a fully functional integration environment for RGB v0.12. What’s more, devs struggle to get a clear picture of the key feature upgrades from v0.11 to v0.12.
## 💻 Our Improvements
Building on the rgb-sandbox repo and existing demo code (incompatible with v0.12) from the
@RGBAssociation organization, we revamped the legacy ` script to enable seamless execution of complex RGB v0.12 demo scenarios. We also created a comprehensive walkthrough report for the demo, breaking down core logic to ease the learning curve for new developers.
## 🎁 Open Source Contributions
✅ Code PR submitted to the official RGB-WG repo: [RGB-WG/rgb-sandbox#
1#](
✅ RGB v0.12 demo walkthrough report: [rgbstashlabs/rgb-sandbox/demo-analysis-en.md](
💡 💡 New developers can dive into the demo mechanics by reading the report, or simply run the ` script locally.

Announcing the BitLight White Paper
BitLight: An Integrated Layer 1 and Layer 2 Architecture for Non-Custodial Bitcoin Operations
BitLight unifies RGB’s client‑side validated assets with Lightning Network payments in a single, non‑custodial architecture. We combine Taproot‑based L1 primitives with L2 execution and cleanly separate signing from node operations, reducing risk and operational overhead while preserving Bitcoin’s security.

$LIGHT Airdrop Claiming — Phase I is now live.
In this phase, eligibility includes $RGB holders and users who have created mainnet UTXOs and interacted with the RGB Faucet.
The RGB Faucet—Bitlight Labs’ first interactive application on RGB mainnet—supported the protocol’s first million-scale stress test. As the first test asset on RGB, $RGB will continue to receive long-term airdrop incentives as the RGB protocol and the Bitlight ecosystem grow. It will also serve as a core asset across key initiatives, including (but not limited to) a decentralized RGB asset marketplace, RGB–Lightning integration, RGB–zk integration, and a Lightning Network–based stablecoin payments network.
If you weren’t eligible in this phase, don’t be discouraged. Our commitment to the RGB protocol and the Bitlight ecosystem is long-term and unwavering. A total of 50.64% of $LIGHT has been allocated to the RGB protocol, the Bitlight ecosystem, and the community, to be released gradually as the ecosystem matures.
We build in cycles, not weeks.
The RGB protocol and the Bitlight ecosystem are at the very beginning of their journey; realizing a global stablecoin payment network will take the steady, collective effort of Bitlight Labs, our peers across the RGB ecosystem, and dedicated community builders and supporters.
We’re here for the long haul—focused, patient, and hopeful. We’ll keep shipping, listening, and improving. Thank you for being early and for believing in what we’re building. Together, we’ll make the vision real.
