How do you see the Job listings ? I have Metamask installed but can't see nothing.
Is the site working ?

No, heartbleed and posterior bugs.
You can restrict RPC to local access but having the bug in there is kinda creepy ...

I wrote a tool some time ago to read both types of data from a running datacoind using RPC calls .

I tried to install the "Aliens" HTML 5 game onto the Datacoin blockchain, as shown in the very interesting Apertus.io tutorial:  
https://www.youtube.com/watch?v=dCyxrtbD4lI

To my surprise, the cost was 159DTC.  Embii then informed me that this was because Apertus.io could only store data in 20 byte chunks, not 128kB chunks, so the cost was prohibitive.  If they used the 128kB chunks of the getdata/senddata methods other wallets could not execute the programs from the blockchain.

Blockchain storage MUST be expensive, very expensive. 159 DTC is actually too cheap IMO.

I don't know what apertus is, but I guess they are using the OP_RETURN size to store data, I fail to see how Datacoin can be leveraged to store this kind of data in front of other (more secure) blockchains.

BTW, as of today, 34Mb of data is stored in the blockchain, besides bytestamp (I don't know what it is), there is nobody really using it.

On the development side, there is a lot of effort to put on it, I don't think any developer will pick the project as it is, too many issues,really old code (still openssl bugs on the main repo), without mentioning the Datacoin own issues with big blocks and network propagation. There is zero incentive for picking this old chain in front of bootstraping a new one, unless you are a hoarder and have millions (literally) of coins.

The chain as it is right now is : unsecure, unreliable, trivially exploitable. Be warned.

They can write the data, but no other client can read it.

In rpcwallet.cpp I saw

senddata(const Array& params, bool fHelp)

...


Yes, this does baffle me.  I thought data was stored without encryption, and that any other client could read it.  We will have to redo the steps that the Apertus.io team went through to understand what went on.  This seems to imply that the block explorer or DTCbrowser (or Apertus.io) must do some sort of decryption.  I also wonder of they were using a client that could not do RPC for getdata.  If I remember correctly the earliest datacoin-hp client could not do RPC.  It was mostly for mining.

I can't believe this site is still open for business scam after so many time.

I guess no one reported them to the police or their hosting, they usually get taken down rather quick.

The internet is amazing.

Also there is an issue reporting the backdoor in Lucky7 in March.

https://github.com/alerj78/lucky7coin/issues/1

And no mention of it anywhere else I can see.
That's simply getting ridiculous.

Anybody can tell if there are currently running nodes ?

TOR is a great addition.

...
In the case of Monero there are some issues with DNS being blocked and required some code changes, but AEON does not use DNS, so we don't have to worry about that issue at all.
...

No one should have ever put a DNS dependency in a coin. DNS is essentially fucked up in terms of security, privacy and decentralization.

I have been following btcsuite (aka Conformal's btcd) for some time and the quality of the codebase is really good.
Schnorr signatures and transaction expiration are very nice additions.

Will follow the project for sure, it will be _interesting_ to see a coin governed by a meritocracy.

Add this one :

Problem: Dr Wright didn't provide cryptographic evidence of his claims.
Thought: It's so fucking easy to do if you have the keys and will end all this nonsense speculation at once.

It seems just someone desperate to get some attention and solve his financial troubles.

Win64 AMD gpu miner update:
With the above parameters (two posts above), the GPU driver crashes after some time and mining stops.
Too unstable to use at the moment.

I built the win64 version of the AMD gpu miner.

On start there are some errors :

Code:
".\groestl256.cl", line xxx : warning: integer conversion resulted in a change
          of sign
        C64e(0x2a86ef4343692aef), C64e(0xf193a6c4c435f1a6),
        ^

Where xxx could be up to 303 and down to at least 225 (I can get the full output if needed).

Also, this :
Code:
"C:\Users\Richard\AppData\Local\Temp\OCL5F33.tmp.cl", line 228: warning: argument of
          type "uchar *" is incompatible with parameter of type "uint *"
        AESExpandKey256(ExpandedKey1);
And finally the results with the following config are 410H/s for a 7950 :

Code:
{
"Algorithms":
[
{
"name": "AEON",
"devices":
[
{
"index": 0,
"corefreq": 925,
"memfreq": 1250,
"fanspeed": 65,
"powertune": 20,
"threads": 1,
"rawintensity": 1024,
"worksize": 16
}
],
}
]
}

It seems going above 1024 makes the system unstable. Also I don't know what is the worksize param.
Anyone willing to share results ?

EDIT: It also crashes after some time with those parameters. The AMD driver crashes and miner stops.

I don't know I might be blind but is there a way to mine this with AMD GPUs?

Thank you

Short answer : No.

Long answer : No.

More ellaborate answer : The only (public) AMD miner for Cryptonight is from Claymore, if he does not develop Cryptonight support there is no AMD support, period. An open source AMD cryptonight miner would be awesome.

I know we're few but please try to keep up some nodes, at least when you can spare the resources. Currently I am only connected to 5 nodes.
The memory requirements are getting huge, 4600MB now on my (24h) node, so it's not easy to have a node up all day. Most VPS don't have more than 2G/4G and most new desktop computers are still sold with 4G, so that's why we see this node scarcity.

Count 1 node for Moo's pool, 1 for Minergate, 1 for the exchange (bittrex?), Smooth's bootstraping server, yours, mine. And some that may be ocasionally up.
(Obviously those are approximated numbers Smiley )

Back from DoS land now. The router gets in some weird state where new connections can't get through, but existing ones usually stay fine.
It'll be like that till the botnet realizes it's getting only 250 IPs mining and moves away. Sorry about that.




Where is your hosting?

I guess he is THE problem.

Minergate is consistently above 50% hashrate with the help of only 1 miner.

No, this has already been addressed in this thread.

I was able to identify a half dozen bad nodes which when blocked cause virtually all of the errors to stop. I don't want to post IP addresses, but if you are having trouble with your log file getting too big and you are able to block IPs in a firewall, PM me and I'll send you the list.


Most errors now come from three IP addresses.
Two of them belong to Minergate and the other to some russian private pool.
Minergate is mining on his own invalid chain as you can see on their block explorer.
