合作进度：

锶多多水业生产线透明化方案完成初稿；

区块链认证相机，已与中国电信外部合作公司完成初步需求调研。

The first draft of the Siduoduo aquatic production line transparency plan completed;

Blockchain-certified camera has completed preliminary demand survey with China Telecom external cooperation company.

EDPoS：

发现四个问题：支链不出块问题；深分叉回滚问题；DPOS共识问题（PUBLISH未去重的问题）；主链回滚后子链未同步回滚问题，解决中。

支链不出块问题和主链回滚后子链未同步回滚问题已编码完成，还在测试中。

EDPoS共识问题已解决并合并到MASTER。

深分叉回滚问题还在测试中。

msvc上的core已可以编译、运行。后面需要新增调整一些脚本。

Four problems were found: firstly, the branch chain did not produce a block problem; secondly, the problem of deep fork rollback; thirdly, the DPOS consensus problem (PUBLISH did not deduplicate the problem); fourth, the subchain was not rolled back synchronously after the main chain was rolled back (in the solving process);

The problem that the branch chain does not block and the sub-chain is not synchronized after the main chain is rolled back has been coded and is still being tested;

The EDPoS consensus issue has been resolved and merged into MASTER;

Deep fork rollback problem is still being tested;

The core on msvc can be compiled and run and some scripts need to be adjusted later.

解决业务分支节点之间分支链区块未及时同步的问题；

测试过程中发现系统崩溃且再也启动不了某些节点的问题，提了一个PR；review关于publish去重的PR。

Solve the problem that the branch chain does not produce blocks caused by the height parameter problem;

Set up a message queue broker node within the local network to solve the problem of large delays in communication between the inside and outside of the wall during the test, resulting in incorrect results;

Participated in the meeting to discuss several issues of the branch chain;

Solved the problem that the branch chain blocks are not synchronized in time between business branch nodes;
