Local Chain

Dart native implementation of TIKI's single user blockchain. Runs 100% locally, no internet, or external dependencies required.

  • Uses a local SQLite database as the file structure.

How to Use

  • Open the localchain with an address Future<Localchain> open(String address, {String? password, Duration? validate})

Note: If any of your project's dependencies uses sqflite (e.g: cached_network_image, flutter_cache_manager...), then for iOS to link correctly the SQLCipher libraries you need to override it in your pubspec.yaml file:

dependency_overrides:
  sqflite:
    git:
      url: https://www.github.com/davidmartos96/sqflite_sqlcipher.git
      path: sqflite
      ref: fmdb_override
  • Append block(s) to the chain using Future<List<Block>> append(List<Uint8List> contents). See /src/block/contents for specific block schemas.

  • Validate chain integrity using Future<bool> validate({int pageSize = 100})

  • Read the chain (in pages) using Future<List<Block>> get({int pageSize = 100, void Function(List<Block>)? onPage})

  • Use Localchain.codec to encode and decode blocks.

Note: block encryption is optional and handled by the wallet implementation. Not the localchain. See wallet for specifics.
