Sync Chain

Dart native implementation of TIKI's backup strategy for localchains

• Uses s3 for immutable hosted storage.

How to Use

• Construct and init the syncchain using

await TikiSyncChain(
    {Httpp? httpp,
    required Database database,
    TikiKv? kv,
    String s3Bucket = 'tiki-sync-chain',
    Future<void> Function(void Function(String?)? onSuccess)? refresh,
    required Future<Uint8List> Function(Uint8List message) sign})
.init(
    {String? address,
    String? accessToken,
    String? publicKey,
    void Function(Object)? onError});`

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

• To sync a block use

void syncBlock(
    {String? accessToken,
    required Uint8List hash,
    required SyncChainBlock block,
    void Function(SyncChainBlock)? onSuccess,
    void Function(Object)? onError})

• Get a block by its hash

void getBlock(
    {required Uint8List hash,
    String? version,
    void Function(SyncChainBlock)? onSuccess,
    void Function(Object)? onError})

• Read the chain using

void getBlocks(
    {void Function(SyncChainBlock)? onSuccess,
    void Function(Object)? onError})
