v1.2.0 — Miner History, Consensus Hygiene, and Tor-Ready Stability

2026-01-04

This release consolidates all improvements since v1.0.0 into a single, cohesive upgrade focused on observability, correctness, and resilience under real-world conditions (including Tor/onion access).

✨ Added

Last 20 Blocks / Miners Panel

• New Last 20 Blocks / Miners view in the Blockchain section.
• Displays recent block heights alongside their associated mining pools.
• Toggleable via [L], mutually exclusive with the Hash Rate Distribution panel.
• Newest blocks shown first for fast situational awareness.
• Built on existing block history — no additional RPC calls.

This panel provides a lightweight, block-native alternative to heavier distribution views, especially useful over high-latency connections.

🔧 Improved

Consensus Hygiene & Correctness

• Replaced hard-coded block and mempool constants with consensus-derived values.
• Normalized block-range calculations using saturating arithmetic for safety and clarity.
• Corrected edge-triggered state handling to prevent unintended cache resets.
• Improved cache stability under high-latency environments (e.g. Tor).

Network & Mempool Observability

• Centralized RPC client construction behind a single builder (proxy-ready).

• Unified timeout and connection behavior across all RPC modules.

• Stabilized background RPC jobs (e.g. miner detection) when accessing nodes over onion services.

• Reduced memory usage by:

  • Switching TXID storage to fixed-size [u8; 32]
  • Skipping unused RPC fields via serde::skip
  • Avoiding redundant deserialization paths

Visual & UX Refinements

• Improved ASCII chart hierarchy:

  • Percentage values remain crisp
  • Horizontal bars dimmed to reduce noise

• Miner names rendered with secondary emphasis for clearer pattern recognition.

• Hash-rate panel now displays actual block window, not time-based placeholders.

• Improved narrow-terminal support and label clarity.

🛠 Fixed

• Corrected mempool transaction lookup to deserialize full JSON-RPC responses.
• Replaced positional assumptions with block-anchored propagation slots.
• Grounded fee metrics in integer sats (floats only at render time).
• Trimmed Keychain stdout before parsing RPC passwords.
• Resolved analyzer warnings and development-time cyclic dependency issues.

---

📝 Notes

• Under Tor/onion RPC access, initial loads (mempool, TX-heavy views) may take longer than LAN connections.
• When using Start9 onion RPC interfaces, ensure the RPC port is explicitly included (e.g. :8332).
• The Last 20 Blocks / Miners panel fills gracefully from 1 → 20 blocks at startup.
• This release reflects a maturation of the v1.x line: fewer surprises, more signal.

🎯 Summary

v1.2.0 is not about adding noise — it’s about making decentralization visible, stable, and trustworthy.

This release strengthens the dashboard as an instrument, not just a display:

• resilient under latency
• faithful to consensus reality
• designed for plurality, not assumptions
