Bitlight Labs publishes a complete disaster recovery solution for RGB assets on Lightning Network channels. The wire-level specification is formalized as bLIP-0072, complementing bLIP-0070.

https://t.co/lPi4mmaKfg

Standard Lightning channels already have a well-defined recovery path for BTC: recover from backup, sweep your funds on-chain using your seed. Solved.

RGB assets in Lightning channels are a different problem. Allocations are client-side validated and stored locally—not on-chain. When a channel loses state, the RGB allocation cannot be reconstructed from chain data alone. It exists only in the counterparty's local stock.

bLIP-0072 defines how to retrieve it.

Bitlight Wallet v1.3.1 Released

We are pleased to announce the release of Bitlight Wallet v1.3.1, introducing key enhancements to RGB asset interoperability and browser extension performance.

What's New:

• RGB Asset Consignment Import/Export — Bitlight Wallet now supports importing and exporting RGB asset consignments for RGB Lightning Nodes on Regtest, shipped alongside rgb-ldk-control-panel v0.0.4. This milestone enables developers to test end-to-end RGB asset transfers across Lightning channels in a controlled environment.

• Chrome Extension Optimization — The Bitlight WASM library powering the Chrome extension has been optimized and upgraded.

These updates reflect our continued commitment to advancing RGB protocol infrastructure and delivering a seamless developer experience. We encourage developers building on RGB Lightning to test consignment workflows and provide feedback.

RGB Lightning Node v0.0.4 Released: Full UTXO Management Support

— Control Panel: https://t.co/4OrTd1RaLG
— API: https://t.co/v8XpDPuEI5
— CLI: https://t.co/ixeCa7G7Vy

We are pleased to announce the release of RGB Lightning Node v0.0.4, introducing comprehensive UTXO management capabilities that provide users with granular control over their Bitcoin UTXOs for RGB protocol operations.

This release focuses on UTXO lifecycle management — a critical infrastructure layer for efficient RGB asset issuance, transfer, and on-chain resource optimization.

Key Features:
• UTXO Overview — Monitor all UTXOs with real-time status tracking, linked RGB asset visibility, and available operation context.
• Create UTXOs — Generate dedicated UTXOs purpose-built for RGB asset issuance, transfer, and management workflows.
• Unlock UTXOs — Release reserved UTXOs and consolidate funds back into available wallet balance for flexible resource allocation.
• Increase UTXO Capacity — Expand the funding capacity of existing UTXOs to support higher-throughput RGB asset transactions.

Efficient UTXO management is foundational to scalable RGB protocol operations on the Lightning Network. This release enables developers and node operators to optimize their on-chain footprint while maintaining full control over asset-linked transaction outputs.

Bitlight Wallet v1.3.0

We've shipped three targeted improvements in this release:

- PayJoin fee optimization: resolved an edge case where transaction construction produced unnecessarily elevated fee rates.
- Rebroadcast logic refinement: transactions now propagate with greater reliability under adverse network conditions.
- Custom API error handling: Esplora exceptions are now surfaced with structured error codes, improving debuggability for integrators.

As always, we build for precision.

Bitlight Labs has completed its Bitcoin Infrastructure Modernization — upgrading from Bitcoin Core 28.x to v31.0 and deploying Cluster Mempool across our stack.

Full technical write-up:
https://t.co/FXzslCZXMH

What changed:

→ Cluster Mempool replaces per-transaction tracking with cluster-based evaluation. Transactions are now grouped and ordered by chunk feerate, enabling more accurate block template construction and stricter RBF semantics.

→ Fee estimation precision improved from 1 sat/vB to 0.1 sat/vB — reducing overpayment in low-fee environments for wallets and protocol-level settlement.

→ mempool-electrs upgraded to v3.3.0 with multi-tier fee estimation (fastest / halfHour / hour / economy / minimum), while preserving full backward compatibility with existing electrs endpoints.

→ Private broadcast support via Tor/I2P for transaction relay, reducing originating IP leakage.

→ Default dbcache increased to 1024 MB on 4GB+ systems, improving sync and validation performance.

For RGB Layer2 infrastructure, this means more predictable CPFP/RBF behavior, cleaner fee selection for on-chain settlement, and a stronger foundation for commitment transactions.

Our approach: stay close to upstream, reduce unnecessary abstraction, build where the protocol is actually moving.

RGB Lightning Node v0.0.3 is now live.

Public repo: https://t.co/4OrTd1RaLG

This release focuses on wallet security and client lifecycle management — laying the groundwork for a production-ready self-custodial experience.

Key updates:

— Wallet Security: Password-protected wallet creation and import. Mnemonic backup now available in Settings with password verification.

— Client Lock: Lock the control panel when stepping away. Password required to resume.

— Exit Flow: Clean exit confirmation with proper session teardown.

The RGB Lightning Node is becoming a complete desktop environment for managing tokenized assets over Bitcoin's Lightning Network — not just a dev tool, but a product.

RGB super-compatibility is not a promise but an engineering discipline enforced with zero tolerance for regression.

RGB on Lightning: Walking with Upstream
https://t.co/lXvjEkEYlG

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: https://t.co/4OrTd1RaLG

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.

[Bitlight Labs⚡️ @BitlightLabs]

We have published the full engineering design behind native RGB Swaps on the Lightning Network.

https://t.co/5BjHPchdEO

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.

Make Bitcoin Smart.
