BitcoinZ Blue v2.0.0 Released - Major Protocol & Reliability Update | BitcoinZ

GLOBAL / INTERNET – The BitcoinZ Community today announces the release of BitcoinZ Blue v2.0.0, a major protocol and reliability update that significantly enhances the official light wallet’s capabilities. This substantial update introduces support for amounts exceeding 21 million BTCZ, implements enhanced wallet recovery mechanisms, and delivers critical reliability improvements across all platforms.

BitcoinZ Blue v2.0.0 represents a significant evolution in the wallet’s architecture, migrating to BitcoinZ-specific protocol implementations while maintaining the bulletproof security and privacy-first design that users have come to expect. The update addresses key user feedback and technical requirements identified since the initial release.

Major Protocol Enhancements

BitcoinZ-Specific Protocol Implementation

The most significant change in v2.0.0 is the migration to BitcoinZ-specific forks of librustzcash and orchard libraries. This critical update removes the upstream 21 million coin supply limitation, enabling proper handling of BitcoinZ’s larger supply model.

Key Protocol Improvements:

Support for amounts up to 21 billion BTCZ with precision mathematics
BitcoinZ-specific Human Readable Prefixes (HRP) for key import compatibility
Enhanced protocol compatibility for optimal BitcoinZ network performance
Improved large-amount transaction handling with string/bigint mathematics

Enhanced Wallet Recovery

Version 2.0.0 introduces HD (Hierarchical Deterministic) address discovery on wallet restoration, ensuring complete account recovery for users. This enhancement applies BIP44 gap rules and automatically discovers all previously used addresses during the restoration process.

Recovery Improvements:

Automatic discovery of all wallet addresses during restoration
Complete transaction history recovery
Enhanced seed phrase restoration reliability
Improved wallet state persistence across app restarts

User Experience Enhancements

Redesigned Key Management

The export modal has been completely redesigned with enhanced functionality and improved user experience:

New Export Features:

Structured key list with wallet order preservation
Individual Copy Key and Copy Line actions for each private key
Copy All functionality for bulk operations
Download to .txt file option for secure offline storage
Visual copy feedback for user confirmation
16/16 character truncation for improved readability

Enhanced Key Import Support

BitcoinZ Blue v2.0.0 expands key import capabilities with support for multiple formats:

Transparent private key import (WIF K/L/5… formats)
BitcoinZ-specific HRP support (btcz-secret-extended-key-main, btczxviews)
Backward compatibility with Zcash-style HRPs
Improved import validation and error handling

Critical Reliability Fixes

Windows Platform Improvements

Significant improvements have been made to address Windows-specific issues:

Windows Fixes:

Resolved “Missing inputs” transaction errors with pre-broadcast UTXO validation
Improved balance persistence after application restart
Enhanced loading and recovery flow reliability
Added comprehensive transaction diagnostics
Fixed balance state updates and synchronization

Cross-Platform Stability

General Reliability Improvements:

Corrected zatoshis→BTCZ conversion in balance change detection
Fixed EUR→BTCZ rounding to prevent “Too many decimals” validation errors
Improved PIN/lock state persistence across app restarts
Enhanced balance change detection accuracy
Cleaned up debug logging for better performance

Technical Architecture Updates

Build System Enhancements

The v2.0.0 release includes significant improvements to the build and deployment pipeline:

Build Improvements:

Protocol buffer compiler (protoc) installation on all CI platforms
Architecture separation for macOS builds
Production DevTools disabled on Windows for security
Enhanced cross-platform compatibility testing
Improved dependency management and version control

Performance Optimizations

Performance Enhancements:

Optimized large-amount calculations with precision mathematics
