A few words about VIZ blockchain

VIZ.World is Graphene Blockchain based on Golos fork.
There are lots of changes in the blockchain in economic and technic parameters. Here are some of them:

• Fixed 10% inflation with 1-year rounds;
• Committee;
• 2 vote for witnesses per account;
• Without peg-asset, only 2 assets: liquid token VIZ and SHARES token;

And lot of other changes.
You can find more in the blog: https://steemit.com/@viz.world

Some of technical changes in Accusta associated with connection VIZ.

In the Viz blockchain was renamed lots of operations related account_history, I had to do backward compatibility. Match old and new operation types. For example:

In this code^:
content_benefactor_reward - new operation name in VIZ
comment_benefactor_reward - old operation name in STEEM and GOLOS
and For steem and golos reward was in VESTS, but for VIZ reward in SHARES
By the way I used VESTS field for building charts and summary by months, and now I do additional data conversion:

$trns['op'][1]['SHARES'] = (double)((str_replace(' SHARES', '', $trns['op'][1]['reward'])));
$trns['op'][1]['VESTS'] = (double)((str_replace(' SHARES', '', $trns['op'][1]['reward'])));

That allowed us to use the database aggregation capabilities.
One example:
Curator rewards by months.

One important fix (fix doubled rewards on charts)

It turned out, in charts we always can see double rewards value.
I found it by testing in the VIZ blockchain. There are small amount rewards in VIZ and we can check it easy.
It came because of operation unwind in requests to MongoDB. The operation created double records for processing. In all requests I added a new condition:
'$match' => ['op.VESTS'=>['$gte'=>0]],
Now in processing used only relevant data.

You can find in Accusta for VIZ

Rewards statistic:

• Author
• Curator
• Benefactor
• Witness

Statistic of Voting for witnesses.

I continue to work about transfer history. There is a lots technical changes in VIZ blockchain, all of this need more time.

It's all for today.
