BlockchainInfo v1.2.2 — Release Notes

This release focuses on accuracy, stability, and maintainability, with improvements across miner attribution, RPC security handling, cache correctness, and internal documentation.

Miner Attribution & Network Insight

• Wallet-first miner attribution restored
  Canonical miner identity now prioritizes known wallet mappings.

• Coinbase tag parsing as a fallback signal
  When wallet attribution is unavailable, sanitized coinbase tags are used as a best-effort fallback.

• Improved specificity for pooled hashpower
  Supports cases where pools (e.g., OCEAN) expose upstream hashpower sources, enabling displays such as:

  • NiceHash
  • NiceHash (via OCEAN)

• Table-driven miner tag classification
  Replaced hardcoded conditional ladders with a centralized, maintainable tag mapping table.

RPC Security & Reliability

• Linux password store support added
  Enables secure retrieval of RPC credentials via the system password store.
• Graceful exit on RPC password retrieval failure
  Prevents hanging or undefined startup states.
• Hidden password input during prompts
  Ensures sensitive input is not echoed to the terminal.

Performance & Correctness

• Reduced cache write-lock contention
  Read-first comparisons minimize unnecessary write locks.
• Restored single-slot cache invariants for difficulty calculations
  Fixes missing difficulty direction indicators by ensuring authoritative reference blocks are always available.
• Tightened block constants and clarified TXID conversion paths

UI & Visual Clarity

• Centralized accent color definitions
• Improved informational text contrast for better readability across terminals

Documentation & Maintainability

• Added documentation for:

  • Linux RPC password support
  • hex_decode() utility
  • Coinbase tag sanitization and classification helpers

• Expanded internal docs in preparation for ongoing development beyond v1.2.2

Summary

v1.2.2 strengthens BlockchainInfo’s role as an operator-grade observer of the Bitcoin network — improving correctness without adding noise, and surfacing nuance without speculation.

This release lays a cleaner foundation for future miner identity evolution while reducing operational friction and edge-case failures.
