[翻译]：让 PW-Core 能够适配后端使用的提案（有 50000 CKB+ 的奖励！！）

我运行Node项目十之八九都是编译不通过的（所以，不好测试）： [屏幕截图 2021-03-05 143430] 所以在此针对 RawProvider简单参与一下。抛砖引玉~ 1、更新pw-core/src/hashers/blake2b-hasher.ts的构造函数，以支持传入私钥，其它不变： constructor(key: string = null) { const keyData = !key || key.length === 0 ? null : Buffer.from(key); const h = blake2b( 32, keyData, null, new Uint8Array(Reader.fromRawString('ckb-default-hash').toArrayBuffer()) ); super(h); } gist: https://gist.github.com/taurenshaman/…

针对IndexerCollector 抛砖引玉~ 实现getBalance。根据ckb-indexer，可以直接调用get_cells_capacity，输入是script和scrip_type，输出的capacity的单位应该是ckb。 // get capacity by lock script async getBalance(address: Address): Promise<Amount> { const data = { data: { script: address.toLockScript().serializeJson(), scrip_type: "lock", } }; const res = await axios.post( `${ this.apiBase }/get_cells_capacity`, data ); /* …

Maybe there are 3 solutions for IndexerCollector?

1. use axios.post directly
2. use RPC class and related classes in ckb-js-toolkit
3. use CKBRPC in @nervosnetwork/ckb-sdk-core
