[dev] 完善bytomcore和bytomcli功能，加入钱包API，并进行集成测试。

2. [dev] debug bytomcore and P2P modules, add the TxPool transaction broadcast function, complete multi-node block consensus synchronous test.

[dev] bytomcore和P2P模块调试成功， 加入TxPool交易广播功能， 多节点之间块共识同步测试。

3. [dev] modify the mining algorithm loopholes , complete the mining algorithm window mechanism, which will be more in line with the actual requirements of AI chip computing. Increase the computational process using a prime table to solve the problem of periodic problems that may cause the invalidation of random numbers in the block header.

[dev] 修改完挖矿算法的漏洞，完成挖矿算法的窗口机制，更切合AI芯片运算的实际要求。增加了计算过程使用素数表来解决周期问题的方法，该周期性问题会导致区块头中的随机数字段失效。

4. [dev] solve the bug of accessToken (access control token) in branch code, debug the package management issues of test code.

6. [issue] solve the problem of asset publishing and node mining problem that’s related to the compatibility of historical version, and we are still tracking and updating.

[issue]提出建立资产发布和节点挖矿不能记住历史版本的问题，并在追踪更新中

7. [fix] solve the block stored procedure due to the characteristics of the j language caused by json codec data can not be saved to the leveldb problem. To solve the problem than the original chain demo can not submit transactions, and continue to follow up to promote the demo test.

[fix]解决了block存储过程中因go语言特性造成json编解码数据无法存到leveldb的问题。解决了比原链demo中的无法submit交易的问题，并持续跟进，推动demo测试。

8. [res] update the lightning network channel and exchange the old version, analyze principle of multi-transaction. Start writing readme document of Alpha1.

[res]完成闪电网络通道更新时旧版本交换，以及多方交易的原理分析。开始比原文档的撰写工作。
