What Was Built

Feature Parity Audit

Formal written comparison of CipherScan vs the legacy Nighthawk explorer (zcashblockexplorer.com). CipherScan implements all 10 baseline features (9 fully matching, 1 different approach — client-side memo decryption instead of payment disclosure protocol). On top of parity, CipherScan adds 30+ exclusive features including pool analytics, turnstile tracking, fork watch, cross-chain swap tracking, and a 43-endpoint public API.

Full document: FEATURE_PARITY_AUDIT.md

Tor Hidden Service

CipherScan is now fully accessible as a Tor hidden service. Users can browse the entire explorer, including the API, without revealing their IP address.

• Frontend: 2v3d5dlxm7kaobrjup6357db7xxjgktmdkyk6cksxox5ts7ucid2dyad.onion

• API: wc6fzsvvx7wuyy2zd66ofbte6ptyb33k5qtsichesbkl5ldfdzgtsjad.onion

Both serve the same data as the clearnet site. No analytics, no IP logging, no third-party resources loaded.

Shielded Supply History - 365 Days

The pool history API now returns a full year of daily data with exact per-pool values (Sprout, Sapling, Orchard).

GET https://api.mainnet.cipherscan.app/api/network/pool-history?period=1y

Visible on the frontend at cipherscan.app/pools with 7d/30d/90d/1y period selectors.

Query Performance Optimizations

• Materialized views for expensive aggregation queries (flow_daily, crosschain summary, supply stats)

• Redis caching with TTL-based invalidation (2–5 min for time-series, 60s for real-time)

• Cursor-based pagination for large result sets (no OFFSET scans on 287M-row tables)

• Client-side streaming CSV/JSON exports (no server memory pressure)

• Incremental turnstile refresh (4x daily, recomputes only affected dates)

Privacy Index Weekly Publication

12 weekly issues published at cipherscan.app/newsletter. Available via RSS at /newsletter/rss. Each issue covers pool composition changes, shielded transaction trends, notable on-chain events, and the weekly privacy score.

Documentation

• API docs: 43 endpoints documented at cipherscan.app/docs with curl examples

• Operational guide: DEPLOYMENT.md covering full-stack deployment, backup, and monitoring

Happy to answer any questions.

Milestone 3.5 - Progress Report

Hey everyone,

Milestone 3.5 deliverables are all complete. This was the supplemental milestone covering the incident response work during NU6.2 and Ironwood preparation.

What Was Built

Fork Watch - Real-time reorg monitoring with orphan vs canonical block comparison and mining pool attribution. 8 reorgs detected and archived on mainnet so far. cipherscan.app/reorgs

Turnstile Tracker - Tracks where every deshielded ZEC goes: held, reshielded, exchange, bridged, or transferred. 42M+ ZEC classified across 934K transactions. cipherscan.app/turnstile

Pool Flow Analytics - Per-pool inflow/outflow with hourly granularity and interactive period selectors. cipherscan.app/pools

Reorg-Proof Indexer - Automatic detection, rollback, and re-indexing. Handles 25+ block deep reorgs without manual intervention.

Ironwood Support - Full NU6.3 support live on testnet: migration tracker, cohort analysis, denomination histogram, 3,804 migration txs indexed, 18,128 TAZ in the Ironwood pool. Ready for mainnet activation July 28. testnet.cipherscan.app/ironwood

Dedicated Database Server - PostgreSQL on a separate host. API response times under 100ms for complex queries.

Happy to answer any questions!
