# TODO

- __CRATES__
  - _CLI_
    - launch
      - if first, test read/write speed, add warning if too low (<2gb/s)
      - check available disk space
      - pull latest version and notify if out of date
    - add custom path support for config.toml
    - maybe add bitcoind download and launch support
      - via: https://github.com/rust-bitcoin/corepc/blob/master/node
  - _COMPUTER_
    - **add rollback of states (in stateful)**
    - add support for per index computation
    - fix min fee_rate which is always ZERO due to coinbase transaction
    - before computing multiple sources check their length, panic if not equal
    - create usd versions of vecs structs instead of having options everywhere
    - datasets
      - `sats` version of all price datasets (average and co)
      - pools
        - highest dominance
        - consecutive blocks
        - max consecutive blocks
        - add indexes back to the mempool.space version of pools as we need the correct one for the API
      - price
        - oracle (https://utxo.live/oracle/UTXOracle.py)
      - cohorts
        - costs basis by percentile
        - address counts relative to all datasets
        - revived/sent supply datasets
        - add `p2pk` group (sum of `p2pk33` and `p2pk65`)
        - add utxo count, address count, supply data for  by reused addresses in groups by address type
        - add more date ranges (3-6 months, 5-7 years and more)
        - % of volume
      - indicators
        - pi cycle
      - https://mainnet.observer
      - https://glassnode.com
      - https://checkonchain.com
      - https://researchbitcoin.net/exciting-update-coming-to-the-bitcoin-lab/
      - https://mempool.space/research
  - _INDEXER_
    - parse only the needed block number instead the last 100 blocks
      - maybe using https://developer.bitcoin.org/reference/rpc/getblockhash.html
  - _INTERFACE_
    - create pagination enum
      - from to
      - from option<count>
      - to option<count>
      - page + option<per page> default 1000 max 1000
    - from/to/count params don’t cap all combinations
      - example: from -10,000 count 10, won’t work if underlying vec isn’t 10k or more long
  - _LOGGER_
    - remove colors from file
  - _PARSER_
    - Stateless
    - if less than X (10 maybe ?) get block using rpc instead of parsing the block files
  - _SERVER_
    - api
      - copy mempool's rest api
        - https://mempool.space/docs/api/rest
      - add extensions support (.json .csv …) instead of only format
      - if format instead of extension then don't download file
      - ddos protection
        - against API params varying in range
        - search
        - fuzzy on typo
          - https://github.com/rapidfuzz/strsim-rs or stick with current impl
          - create map of all single words
          - do some kind of score with that ?
      - discoverability
        - catalog (tree/groups)
        - search
      - failover to `/api`
      - no HTML / redirects ?
      - change `/api/vecs/{index}-to-{metric}` to `/api/{metric}/index`
      - change `/api/vecs/query` to `/api/bulk`
      - support keyed version when fetching dataset: {date: value} / {date: [value]}
    - add support for https (rustls)
  - _STORE_
    - save height and version in one file
- __DOCS__
  - _README_
    - add a comparison table with alternatives
    - add contribution section where help is needed
      - documentation/mcp/datasets/different front ends
    - add faq
- __WEBSITES__
  - _PACKAGES_
    - move packages from `bitview` to `/packages` or `/websites/packages` or else
    - move the fetching logic from `bitview` website to an independent `brk` package which could be published to npm
      - https://www.npmjs.com/package/@mempool/mempool.js
      - auto publish with github actions
  - _BITVIEW_
    - explorer
      - blocks (interval as length between)
      - transactions
      - addresses
      - miners
      - maybe xpubs
    - charts
      - selected unit sometimes changes when going back end forth
      - add support for custom charts
      - price scale format depends on unit, hide digits for sats for example (if/when possible)
      - shows certain series as [scatter plots](https://github.com/tradingview/lightweight-charts/issues/1662) with a solid sma/ema
        - mainly datasets with a big variance like raw `hash_rate`
      - hide pane if no series on it
      - fix (and reset) pane size (50/50) when changing charts
      - units: add short name / long name / title
      - verify that "compare" folders aren't missing charts/datasets
      - legend
        - add link to explanation for each name (to glassnode ?)
    - table
      - pagination
      - exports (.json, .csv,…)
      - improve dataset selection
      - display 1k values (instead of 10k) but to avoid caching multiple times the same values apply everywhere
    - search
      - improve
      - datasets add legend, and keywords ?
      - support height/address/txid
    - api
      - add api page with interactivity
    - glossary ?
    - nav
      - move share button to footer ?
      - when clicking on already selected option, pushes to history, bad !
    - global
      - improve behavior when local storage is unavailable
        - by having a global state
      - font:
        - https://fonts.google.com/specimen/Space+Mono

    - keep as many files as possible [under 14kb](https://endtimes.dev/why-your-website-should-be-under-14kb-in-size/)
    - No classes: https://news.ycombinator.com/item?id=45287155
- __GLOBAL__
  - check `TODO`s in codebase
  - rename `output` to `txout` or `vout`, `input` to `txin` or `vin`
