Notice

TensorCash Explorer
===================

This software is a modified version of TSCScan by rHuhu
(https://tscscan.xyz), release v1.0.0, which is distributed under the MIT
License. The original copyright and permission notice is in LICENSE:

    Copyright (c) 2026 TSCScan contributors

Modifications are Copyright (c) 2026 TensorCash contributors and are released
under the same MIT License (see LICENSE for the full terms).

Changes made in this version (frontend only; Indexer and API are unchanged):

- TensorCash theme: brand tokens and override stylesheet
  (frontend/static/tensorcash/), TensorCash lockup, favicon and logo, and
  charts drawn in the TensorCash palette (frontend/static/chart-colors.js,
  --tc-chart-* tokens).
- Pricing removed: the Market adapter is pinned off, so no price, market-cap,
  volume or fiat value is shown or fetched. The upstream Market code is kept
  unchanged.
- Endpoint fallback: API origins accept an ordered, comma-separated list. The
  browser and the page server fail over between them on network errors,
  timeouts and 5xx responses, prefer the most-synced endpoint and skip lagging
  ones (TSC_EXPLORER_API_FALLBACK, TSC_EXPLORER_API_TIMEOUT_MS,
  TSC_EXPLORER_API_MAX_LAG_BLOCKS, TSC_EXPLORER_API_REPROBE_SECONDS).
- Footer: attribution to TSCScan, a /license page reproducing the MIT
  licence, and a configurable API documentation link
  (TSC_EXPLORER_API_DOCS_URL, default https://tensorcash.org/docs).
- VDF ticks: per-block tick, tick assessment and cumulative ticks on block
  pages, block lists and Home, read from the official TensorCash explorer API
  (TSC_EXPLORER_{MAINNET,TESTNET}_TICKS_ORIGIN; empty disables).
- Home: difficulty-implied tokens/s from the API's network overview.
- Chain data parsed in the browser from raw transactions (ports of TensorCash
  Core parsers): per-output asset legs on transactions, the full asset
  registration record, and public ICU document metadata, witness,
  attestations and TSC-ICU-CONTEXT-1 clauses. Block model and PoW hash on
  block pages. Registry state and the PoW hash come from the official
  explorer API (TSC_EXPLORER_OFFICIAL_FIELDS; off disables).
- Assets: in-browser decryption of holder-only ICU documents with the
  holder's key (ChaCha20-Poly1305 per TensorCash Core; the key never leaves
  the browser).

Third-party component added by this version: fzstd 0.1.1 by Arjun Barrett
