Electrum Dark

[UdjinM6]

That could be it.

Though, looking at Poolers source code for the old version the only time he messed with the POW was for the actual electrum-client and not the server. With litecoin using scrypt instead of sha256 I'd assume if it was needed it would need to be edited in both the server and client.

https://github.com/pooler/electrum-ltc-server/compare/spesmilo:master...master

I'll spend some more time on it.

Hmm.. strange if it works at all... that's what my logic was based on - for example:
This https://github.com/Propulsions/electrum-drk-server/blob/master/src/blockchain_processor.py#L655 uses hash_header I mentioned before and stores last_hash
and then https://github.com/Propulsions/electrum-drk-server/blob/master/src/blockchain_processor.py#L662 uses that last_hash to call "darkcoind getblock <last_hash>"
The last statement will definitely fail if hash_header used sha256d to form last_hash earlier.

 

[Propulsion]

Alright. I've imported the hash function from p2pool. I'm able to start and stop the server with no issues. Once again, I'm rebuilding the full blockchain_headers file from scratch.

The only thing that looks concerning is the coin count:

Looking above it shows a block height of 12051 with a coins in database of 806 940 910 993 317.(806 trillion) That can't be right it should be 2,924,324.0 DRK
Although, looking at a post on BCT on Electrum,
Block height is 296956 while Coins in database shows 1 267 617 386 701 994 which is absolutely wrong.(over one quadrillion)

I'm going to go ahead and create the database. I'm not 100% sure it's a good hash function though at this time.

well now you got darkcoin hash, but you also need darkcoin subsidy i guess, this calculates the block value and thus the total coins.

Isn't this fun?

 

[vertoe]

Tell me about it, currently porting bitcoin 0.10 to work with the darkcoin network... fun!

 

[moli]

I wish I could understand all this stuff so I could have fun too!!!
:sad:

 

[crowning]

Isn't this fun?

The subsidy part is probably the most simple one of the tasks waiting for you, it's in main.cpp, method GetBlockValue().

Don't forget the yearly decline, it already applies!

 

[akhavr]

I will, but now I'm very short on time, sorry.

darkzero
akhavr
Propulsion
flare

I merged all electrum threads, you guys should coordinate your effords, else we never get a final result

ElectrumDRK task force...

 

[ELM4ever]

I found the problem with the wrong coinbase reporting on the server. I have a working version, but still want to finish building all the UTXOs before declaring victory - 8 hours more to go...

Will do a pull request to Propulsion's Github account when satisfied.

Working on the client in the meantime. Should be simple.

 

[souptacular]

I'm loving all the progress on this. Great work guys/gals.

 

[ELM4ever]

Finally got the UTXO to build... Got less than 3 DRK difference on coinbase (over 5M DRK) between the UTXO and Chainz block explorer.. interesting... It used to be a perfect match until half way down the blockchain...

Still working on the client... managed to get a transaction to show up in my wallet

More info tomorrow...

 

[vertoe]

Interesting, I just found another group working on electrum-drk (they claim)

.... ok ... to the moon!

 

[ELM4ever]

It is a known fact that Electrum servers are not rewarded with their work (BTC - LTC - ..._). Sadly...

If Darkcoin wants to have Electrum-drk servers to support the (SPV) Electrum feature - someone will have to support them.

If an Electrum-DRK solution can be found, Darkcoin will have to fund a minimum of 3 servers. Can Darkcoin do that?

To run an Electrum-DRK server would require at least 8GB Ram and 40GB HD - do the math with cloud servers... times 3...

Ok, we need to get some overview, this is what github has to offer currently:

??? redtocatta who are you? ;-)

Will reorganize the OP.

 

[vertoe]

If an Electrum-DRK solution can be found, Darkcoin will have to fund a minimum of 3 servers. Can Darkcoin do that?

Yeah that should be no prob. I can contribute at least one of such machines.

 

[flare]

Yeah that should be no prob. I can contribute at least one of such machines.

Me too, at least two heavy duty machines available. eduffield will bring in another machine for sure which i can manage.

This is me, also owning the domain electrum-drk.org
