# TODO

- __crates__
  - _cli_
    - check disk space on first launch
    - add custom path support for config.toml
    - maybe add bitcoind download and launch support
      - via: https://github.com/rust-bitcoin/corepc/blob/master/node
    - test read/write speed, add warning if too low (<2gb/s)
    - pull latest version and notify is out of date
  - _computer_
    - **add rollback of states (in stateful)**
    - remove configurable format (raw/compressed) and chose sane ones instead
      - linear reads: compressed (height/date/... + txindex_to_height + txindex_to_version + ...)
      - random reads: raw (outputindex_to_value + ...)
    - add prices paid by percentile (percentile cost basis) back
    - add support for per index computation
    - fix min feerate which is always ZERO due to coinbase transaction
    - before computing multiple sources check their length, panic if not equal
    - add oracle price dataset (https://utxo.live/oracle/UTXOracle.py)
    - add address counts relative to all datasets
    - make decade, quarter, year datasets `computed` instead of `eager`
    - add 6 months (semester) interval datasets to builder
    - some datasets in `indexes` can probably be removed
    - add revived/sent supply datasets
    - add `in-sats` version of all price datasets (average and co)
    - add `p2pk` group (sum of `p2pk33` and `p2pk65`)
    - add chopiness datasets
    - add utxo count, address count, supply data for  by reused addresses in groups by address type
    - add more date ranges (3-6 months and more)
    - add puell multiple dataset
    - add pi cycle dataset
    - add emas of price
    - add 7d and 30d ema to sell side risk ratio and sopr
    - don't compute everything for all cohorts as some datasets combinations are irrelevant
      - addresses/utxos by amount don't need mvrvz for example
    - add all possible charts from:
      - 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
      - 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
  - _parser_
    - save `vec` file instead of `json`
    - support lock file, process in read only if already opened in write mode
    - if less than X (10 maybe ?) get block using rpc instead of parsing the block files
  - _server_
    - api
      - add extensions support (.json .csv …)
      - if format instead of extension then don't download file
    - add support for https (rustls)
    - lru cache
  - _vec_
    - add native lock file support (once it's available in stable rust)
    - improve compressed mode (slow reads)
    - add ema support
- __docs__
  - _README_
    - add a comparison table with alternatives
    - add contribution section where help is needed
      - documentation/mcp/datasets/different front ends
    - add faq
- __websites__
  - _default_
    - explorer
      - blocks
      - transactions
      - addresses
      - miners
      - maybe xpubs
    - charts
      - improve some names and colors
      - remove `sum` series when it's a duplicate of the `base` (in subsidy for example)
      - selected unit sometimes changes when going back end forth
      - add support for custom charts
      - separate z-score charts from "realized price" (with their own prices), have 4y, 2y and 1y
      - price scale format depends on unit, hide digits for sats for example (if/when possible)
    - table
      - pagination
      - exports (.json, .csv,…)
    - search
      - datasets add legend, and keywords ?
      - height/address/txid
    - api
      - add api page with interactivity
    - global
      - **fix navigation/history**
      - move share button to footer ?
      - Use `ichart.createPane()` in wrapper
      - improve behavior when local storage is unavailable
        - by having a global state
- __global__
  - check `TODO`s in codebase
