Balance issue

[ArtjomP]

Hello there! I got a balance issue from yesterday.

var network = Network.Main;
var client = new QBitNinjaClient(network);
var destination = BitcoinAddress.Create("1911V1aepiPWZxVKghp9jV9JwvUAhH1enp", network);
var balanceModel = await client.GetBalance(destination, true);

And I get balanceModel.Operations.Count == 0 But actually: balance

Could you help me, please?

Thank you in advance!

@ArtjomP yestersday I swtich the storage because I reindexed the whole chain so we pay less. Sadly, it seems there is an issue in the indexation, I won't be able to fix it quick but checking it.

[ArtjomP]

Thank you! If I can help you somehow you can count on me.

[NicolasDorier]

@ArtjomP so we stopped indexing properly from block 539,700. I will fix this, but because it is very very slow to sync, it might take 3 or 4 days to go back to normal.

Hi Nicolas, first of all - the QBitNinja rocks! The really most easy solution for blockchain integration. We are experiencing these issues too, so I thought maybe you can share Azure template for your setup with the QBitNinja server. It could help us a lot to set up the node quickly.

Also, according to your explanation on how it's working, it sounds possible to replace ServiceBus with AWS SQS, Storage with S3 and web app with the AWS Lambda. A lot of folk would benefit from the AWS port, what do you think?

[NicolasDorier]

It is still synching, that's why there is still the problem... It is so slow that it might take again 3 or 4 days :(

AWS port is not possible. I am using all kind of trick to take the best of Azure storage so that it can sync.

I do not maintain that much this project anymore, because I now believe that the best way to build your project is by having a solution which do not require indexing the whole blockchain and which can easily get the balances of HD wallets (like https://github.com/dgarage/NBXplorer/).

QBitNinja is good for learning and for simple applications, but I think it is now way too slow to sync to be practical.

[Bassist067]

thanks, I'll give it a try. What should I use for the transaction sending? The NBitcoin is literally the only viable solution for .NET Development as I see it

[NicolasDorier]

@Bassist067 Check the docs in NBXplorer project. You also have some sample_tests in the project you can take a look to.

Thanks @NicolasDorier, this guy https://api.qbit.ninja/balances/1Gpwq53eau1AyNADgpBrNJW6p1yE4Px8VX has the same issue :(

Hi, @NicolasDorier! How the sync is going, how long approximately left to wait?

[GnWorld]

Still in sync?

[bitcoinbrisbane]

yay, mine has now synced!

Hello, @NicolasDorier! I see some of you say it can be used, but I can't do it here. Is it not completely good yet? Please let me know if you understand. Thank you.

[bitcoinbrisbane]

@zeuspay seem to be up to July 2019

[zeuspay]

@bitcoinbrisbane What do you mean?

[NicolasDorier]

Almost done, still like 10K blocks. Sorry for that. :(

[bitcoinbrisbane]

@bitcoinbrisbane What do you mean?

Ive monitoring old addresses. An address first seen in July started working :)

[bitcoinbrisbane]

Almost done, still like 10K blocks. Sorry for that. :(

Awesome! I've done a lot of refactoring to use NBXplorer. Be a shame to see QBitNinja die. Perhaps we could mirror?

[NicolasDorier]

@bitcoinbrisbane it won't die, it is quite low maintainance, the storage is expensive but I guess we can keep it up.

[bitcoinbrisbane]

More than happy to tip a few sats!

[NicolasDorier]

I would advise you to self-host qbitninja so that it is faster for you and it does not break if I do a bad update. But the main server will still be here.

Synchronizing stopped on 592299 block.

[NicolasDorier]

@littleAnarchy no it did not, normally it is now fully synched.

Nicolas, It is very likely that not all the data entered the index. Example:

@NicolasDorier Hello, I have successfully operated the coin this morning, but I can’t use it in the afternoon.

[NicolasDorier]

@bozhday it seems you are right. I will fix it tomorrow, maybe missing a few last blocks. Unsure why it did happen though.

[NicolasDorier]

@bozhday @zeuspay it is synching the last blocks, should be back in normal in a few hours.

[bozhday]

Nicolars, excellent work, thank you!

[NicolasDorier]

Can I close that everybody is good now?

[bitcoinbrisbane]

Can I close that everybody is good now?

Working for me

[NicolasDorier]

closing this as nobody complains
