Can anyone give me an estimate on the size of the blockchain?  I'd like to install devcoind on an older machine (~15gb of free HDD space) and I'm not sure if the blockchain can fit.
DVC blockchain size is about 700M now.

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...

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

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.

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?
