Subscan issues

[mochet]

A list of issues found with Subscan so far:

1. Circulating issuance number appears to be wrong. It appears to not be calculating the vested amount correctly.

2. Balance History chart is not available or not populated

   • https://joystream.stg.subscan.io/account/j4To6jgKfy8MgiMRDXzc15ggN8AnFAm3QJ4VXEwL3uBNMDd2s?tab=balance_history

3. Charts section includes some broken charts (https://joystream.stg.subscan.io/tools/charts)

   • Daily Holder
   • Daily Average Block Time
   • Daily Native Token Circulating Supply
   • Daily Vesting Schedule

4. Charts section includes some charts that don't apply to Joystream (https://joystream.stg.subscan.io/tools/charts)

   • Treasury Available Income
   • Treasury Expenses

5. Fees are in wrong units. Appear to show fees in $HAPI rather than $JOY

   • https://joystream.stg.subscan.io/extrinsic/0xe8f5a2125a4cc0aba3456f597e22133e7a5830f64893a86dfbadffdc141b4e58

6. Distribution information includes Democracy and Election pallets which are not on Joystream

7. Inflation rate appears to be wrong--shows 4.22% but is supposedly around 1.1%

   • Explained a bit further in this issue: https://github.com/polkadot-js/apps/issues/9860
   • https://joystream.stg.subscan.io/validator

8. reward points are only tracked since era 956 and are missing for the first 239 days.

   • https://joystream.stg.subscan.io/era?address=j4STQtK3EE3BqcNiwzW5UxN9mBiTcEQosL113JQTXzTJFU8C6&page=5

9. the daily vesting release is incorrect https://joystream.stg.subscan.io/tools/charts?type=vesting_release It states 551 kJOY release each day until 10th Dec and 306 kJOY after that. But actually it should be around 1 MJOY each day until 10th Dec and 820 kJOY after that.

You mentioned this on Discord but when I click on that link, I can go to page 38 which shows reward points from era 85: https://joystream.stg.subscan.io/era?address=j4STQtK3EE3BqcNiwzW5UxN9mBiTcEQosL113JQTXzTJFU8C6&page=38

Not sure what you are looking at. Following your link there are -. :)

oh sorry, I didn't properly read what the problem was when you shared it. Will add it to the list

9. timestamp extrinsics do not appear. https://joystream.stg.subscan.io/extrinsic?address=&module=timestamp&call=all&result=all&signedChecked=signed%20only&startDate=&endDate=&startBlock=&timeType=date&version=2001&endBlock=

10. the daily vesting release is incorrect. https://joystream.stg.subscan.io/tools/charts?type=vesting_release It states 551 kJOY release each day until 10th Dec and 306 kJOY after that. But actually it should be around 1 MJOY each day until 10th Dec and 820 kJOY after that.

You can get timestamp extrinsics to show by changing sign filter from signed only to all: https://joystream.stg.subscan.io/extrinsic?address=&module=timestamp&call=all&result=all&signedChecked=all&startDate=&endDate=&startBlock=&timeType=date&version=2001&endBlock=

will add this to the list

Hi, @mochet we have fixed most issues mentioned above. As for issue 7, we will look into it and customize the inflation rate soon. As for issue 8, we can only sync 120 era for now, thus no data for previous eras. As for vesting related issue, we've re-synced corresponding data, please check again.

The issue 7 has been updated！

On the main page, when clicking Large transfers, no transfers will show.

On the main page, when clicking Large transfers, no transfers will show.

Thank you for your careful testing and feedback. After our investigation, we found that this is not a bug. This list shows transfers with a real-time value of more than 100,000 USD. There is no qualifying data for now.

The circulating supply is not accurate

Compare to CMC profile

If you want to see how it is computed and do a comparison with what you are doing, please consult calculateCirculatingSupply function at this link: https://github.com/DzhideX/status-endpoint-joystream/blob/9f72f34f4cb23f5a4d3c85960a640cca3094d5a4/src/joyApi.ts#L385

I have two questions

• Why system.account free value < miscFrozen
• Why is the lock taking the minimum value?

[bedeho]

@cuckooemm Hey, so, I think we will try to just simplify this, we have started an issue to fix this, hopefully very soon.

The API result for https://joystream.api.subscan.io/api/scan/transfers is incorrect. Or am I somehow doing it wrong? Specifically, the total value from the results is different from the values in the UI https://joystream.stg.subscan.io/transfer

parameters used

{
    "row": 11,
    "page": 1,
    "include_total":true,
    "address":"j4WoRUngU6YgJ7ucn1MpMQCxKZsk2MsQtWJu39r3eQjNQayV4",
    "direction":"received"
}

API result

            }
        },
        "transfers": [...
        ]
    }
}

But result here shows that total received is 1,739,000 JOY.

We have fixed this issue, thanks for the feedback

Hey @cuckooemm, we have now cleaned up the implementation of this routine, here is the new implementation, but output is still the same as before.

https://github.com/Joystream/status-endpoint-joystream/blob/master/src/joyApi.ts#L403

It is now also heavily documented.

If you want to read methodology, read background issue: https://github.com/Joystream/status-endpoint-joystream/blob/master/src/joyApi.ts#L403

[bedeho]

I think one clear distinction between what we are doing and what is going on in Subscan is that tokens that are used for nomination/validation are counted as circulating by us, since they are basically available for sale on market with very short time latency, while you are counting it as not circulating.

[bedeho]

It seems this is in conflict with what CMC & Coingecko does for example, look at Polkadot for example.

CMC

Coingecko

Subscan

Hi @bedeho，

In general, it is true that Subscan's approach to calculating circulation differs from the methods employed by CMC/Coingecko. However, our calculation method has received recognition from Substrate ecosyste, and it is deemed to be more suitable for the Substrate ecosystem. Nevertheless, we are very open to adapting our circulation calculation method to align with the characteristics of the Joystream network, as this is indeed a crucial data point.

Regarding the slow progress, there may have been some misunderstandings. Upon seeing the issue, our team assumed that further development should proceed after the issue is merged. This misunderstanding may have caused a delay. Following the merger of this issue, we have initiated the development plan again and anticipate releasing a new test version for your team to test today. If the new version proves to be suitable for your team, we are ready to proceed with the official release and announce it to the community! I am eagerly looking forward to this moment.
