Editor’s Note — added 20 May 2026 This page is retained as a historical record. The work described here was carried out by the NBW Foundation (formerly the Elastos Foundation) — not by Elastos DAO. Elastos DAO did not issue, fund, operate, guarantee, or approve BTCD or any of the activity reported on this page. For the current position of Elastos DAO and Elacity Labs, please read: Elastos, Where We Stand Today. About this specific update: This is a weekly report from the NBW Team covering Taproot-based BTCD protocol evolution, PG Chain integrated BPoS block production testing, and 180-day BTCD staking support. The NBW Team is part of the NBW Foundation. Elastos DAO did not commission, fund, supervise, or approve any of the work reported here. |
This week, the NBW team advanced several deep infrastructure pillars simultaneously: Taproot-based protocol evolution, full-spectrum PG Chain integrated BPoS block production testing, and 180-day staking support across contracts and applications.[1] Multi-scenario consensus testing confirmed correct sidechain behavior through BPoS degradation, DAO-only fallback, and mainchain POW/DPOS transitions.
In parallel, BTCD Protocol Taproot contract development moved from research into working implementation, and long-duration staking is now fully supported at the application layer. Together, these efforts materially strengthen BTCD’s security, flexibility, and long-term governance readiness. This work supports the ongoing evolution of the BTCD protocol as a Bitcoin-anchored financial system.
Key Work This Week
- BTCD Taproot Technology Development: Completed Taproot script contracts, unlock branches, and order-related logic, forming a concrete implementation base for BTCD protocol evolution.
- Comprehensive PG Chain BPoS Block Production Testing: Finished Oracle–contract integration testing and validated BPoS CRUD operations. Completed multi-scenario consensus testing including BPoS insufficiency, DAO node+BPoS switching, and mainchain POW/DPOS transitions.
- 180-Day Staking Period Support: Fixed staging SPV proof submission issues and completed full BTCD dApp support and verification for 180-day staking orders.
- BTCD Order Issue Resolution: Identified outdated BTC header contracts as the root cause of order closure failures and processed the majority of affected orders.
- PG Chain Blacklist Feature Testing: Completed PG sidechain blacklist testing, confirming BPoS deregistration behavior and registration restrictions for blacklisted nodes.
- Product Quality Optimization: Verified BTCD Dashboard ECO chain fixes and advanced EE Wallet intent-level optimizations.
NBW 2.0 — Strategic Progress This Week
BTCD Taproot Technical Solution Development
- Completed Taproot script contract development
- Completed Taproot unlock branch logic
- Advanced Taproot order-related functionality
These components represent a concrete step toward greater protocol flexibility and future-proof scripting within BTCD.
GSM (Gold–Silver Minting) Handover
- All GSM-related code and repositories were formally handed over to the PG community
- PG community now assumes responsibility for operations, maintenance, and further development
PG Chain BPoS Block Production Mechanism Testing
Oracle Service Verification
- Verified Oracle–contract interactions and BPoS CRUD operations
- Tested behavior under insufficient voting power and stake expiration
- Validated BPoS status transitions (inactive, illegal)
- Updated Oracle and contract scripts to support new test paths
Consensus Degradation & Recovery Testing
- Tested PG sidechain fallback to DAO Node-only block production when BPoS nodes are insufficient
- Verified DAO Nodes → DAO Nodes+BPoS recovery after BPoS re-registration
- Tested sidechain behavior during mainchain POW mode
- Confirmed correct recovery after mainchain returns to DPOS
Cross-Chain Validation
- Validated mainchain deposits and sidechain withdrawals under DAO Nodes-only and DAO Nodes+BPoS consensus modes
PG Chain Blacklist Feature Testing
- Verified full blacklist lifecycle and query paths
- Confirmed that blacklisted BPoS nodes can deregister but cannot re-register
- Tested consensus logic and random selection across varying BPoS registration counts
BTCD 180-Day Staking Support
- Resolved SPV proof service outage blocking staging submissions
- Completed BTCD application support for 180-day orders
- Verified dApp-side modifications through testing
BTCD Order Issue Resolution
- Identified outdated BTC header contracts as root cause
- Processed and resolved most impacted orders
- Continuing follow-up on remaining edge cases
Product Optimization
- Regression-tested BTCD Dashboard ECO chain fixes
- Optimized EE Wallet intent handling and verified changes locally
- Completed testnet mainchain term transition, DAO Node registration, and voting processing
Next Week’s Focus
- Continue refining Taproot functionality and validation
- Complete remaining BPoS block production testing and improve Oracle stability
- Finalize 180-day staking edge-case resolution
- Advance BTCD Dashboard and EE Wallet fixes
Conclusion
This week marked a transition from exploration to validation across several critical layers of the NBW stack. Taproot development moved into working implementation, BPoS consensus was stress-tested across real degradation and recovery scenarios, and long-duration staking is now fully supported end-to-end. Alongside continued product hardening and the GSM handover to the PG community, these efforts significantly strengthen BTCD’s technical foundations. The team will continue executing against the roadmap with a focus on stability, flexibility, and decentralized governance readiness.
