Below is a quick summary of the Hive core work done by the BlockTrades team last week.

Hived testing and bug fixes

Status: Hived is feature complete and is undergoing testnet testing by the witnesses. So far, I think the testing is going very well.

Earlier in the week, testnet-based testing discovered a bug in the airdrop code for hardfork 24, which was fixed here:
https://gitlab.syncad.com/hive/hive/-/merge_requests/106/diffs

And this weekend, testnet testing uncovered another bug in this code, which was fixed today:
https://gitlab.syncad.com/hive/hive/-/merge_requests/107/diffs

There are no currently known issues with hived that should affect the hardfork date.

Hivemind progress

Most of our work this week continues to be focused on hivemind testing and fixes.

Hivemind initial sync testing

We also ran “hivemind sync” tests this week. When hivemind is started for the first time on a server, it must first load and organize all the blockchain data into its internal database format. After that, it enters a “live” sync mode where it adds new blocks as they are produced.

In our tests, the initial sync process took just under 4 days (there’s a lot of data in the Hive blockchain). This was our first successful sync of the entire blockchain using the new Eclipse version of hivemind, so it’s a significant milestone for our work on Eclipse.

Below is the database space consumed by Eclipse hivemind tables after a full sync:

       table_name        |   total    |   index    |   toast    |   table

Plans for upcoming week

The witnesses are continuing to do testnet-based tests of hived. That will likely be completed this week.

Our team will continue with fixes to hivemind. Most recently, we realized that we need to implement the reputation code directly inside hivemind now. This is just a reimplementation of the existing algorithm, not a rewrite, which would be a much longer task.

Ideally, we’ll complete hivemind work this week, which would allow us to keep the Sept 16th hardfork date. If not, we’ll likely push the hardfork date to the 22nd.
