[DVC]DevCoin - Official Thread - Moderated

I can implement it but gonna require a good server to keep a separate index of Addresses from all transactions and to calculate balances, it will constantly fetch transactions from seed nodes and serve the website so has to be separate infrastructure for resilience.

Is there any chance to have and ongoing bounty of half a share in order to pay an small VPS? I plan to implement historical value in several currencies as well (http://www.devtome.com/doku.php?id=devcoin_bounty_now#block_explorer_with_historical_value), but is gonna take longer...

Feedback is welcome!

Nice work, need to be able to search by address ideally for my useage though.

Does the utxo set not have what you need?

@sidhujag, do you mean this: https://bitcoin.org/en/developer-reference#gettxoutsetinfo ?

You can use that function but get the utxo of each address or the address you search for from there in a custom function. You can get the size of utxo and calculate balance like the function does.

I'm using the RPC API. Looking for a solution in the forums and stackoverflow, there people suggests to generate a separate database as explained before. Do you think it is viable to add indexes for balances and addresses as well as implementing new functionality for retrieving that info via the RPC API?

Just copy the existing rpc function we spoke about but pass in a searchable address and filter based on that... Call the function via interface.

That way search might take a while but your not storing another db.. Unless feature is heavily used then might make sense to optimize to a new db.

@sidhujag, I found this: https://counterparty.io/docs/bitcoin_core/ a patched Bitcoin core v0.10.2 that adds addrindex. And yeah, it will be heavely used so...

gettxoutsetinfo accepts no params so I'm lost there. We are trying to get balance of all address, not only the ones in local wallet.

The utxo db has info of all addresses.. Addrindex might be doing just that, you can add that to dvc core.. Why not use bitcore? Someone did a bitcore port to dvc you know that? We have an insight dvc explorer.

I picked up Devtome writing again. Good times will visit Devcoin at some point.

It has been years since I have looked at this coin!

Estimated DVC inflation or total supply over the next 10 years?
The information is needed for http://alt19.com/19/cryptocurrency.php

Thank you.

and do you have or plan to have checkpoints?
merged mining?

[K1773R]

[sidhujag]

and do you have or plan to have checkpoints?
merged mining?

Yes to both

Last time installing the Devcoin wallet it was pretty straight forward. This time there is an error:

Code:

Downloading receiver_0.csv base file./home/booner/.devcoin/receiver/receiver_0.csv
Warning, writeFileText in receiver.h won't write the file:
/home/booner/.devcoin/receiver/receiver_0.csv
because the text is blank.
No coin addresses were found, there may be something wrong with the receiver_x.csv files.

Made sure it was not a permission thing. Looks like the receiver_0.csv is not available.

Any insights?

Thanks,

- Nova

Hiya Nova!  How many files are present in that directory? Are there any other .csv files in there?

Yes to both

thank you, what kind of checkpoints?
did you reverse transactions before?
how do you control checkpoints?

and use the search function!

I'm using the search mostly.
I've never asked anything before, now I have to.
I'm doing a revision and there are some questions, and I have to get answers from devs/community to avoid any mistake.

There appears to be no csv file Qtera.

Would it help if I send you the .csv file? It doesn't seem dependent on the wallet itself, so I think it shouldn't be a problem, right? Did you try making an empty file?
