LAST WEEK’S Top Commits

Last week, our main job was to enhance Testnet’s stability and performance.

We fixed some issues with the synchronization module, added tags at the end of synchronization, and added duplicate checks for the chunk header. Adjusted the synchronous retry logic to ensure that the current tail node is consistent during the first synchronization retry. We improved the network synchronization performance by changing the returned data from the block’s complete information to a block hash in the synchronization interface, reducing the amount of network request data. When getting chunk information, added quick exit mechanism if most returned zero chunk header,

In addition, we have made compatibility adjustments to transaction data, serialized upgrades and compatibility with binary-type transaction payloads. We have standardized log printing and adjusted it accordingly, adding more metrics to do performance statistics.

At the same time, we have completed the JavaScript version of the address and transaction generation code, for the future web version of Nebulas official wallet to use.

The summary of last week is as follows:
