Found this after using yam and its increased my hashrate and of course is open source.

Cheers mate. Donated ~0.0033BTC change i had in a wallet. Thanks, keep up the good work.

Been reading about things like MirageOS and Unikernels. Mirage turns OCaml code into a kernel that runs directly under Xen, no OS as such just enough code to do its job,

There is also this: http://ocaml-bitcoin.forge.ocamlcore.org/

OCaml library for bitcoind interaction. Im thinking, would an OCaml unikernel that exposed the bitcoin API, then optionally applied some logic and passed through the request to an off-line (no internet) bitcoind provide some value?

e.g. no OS or stack to attack, attack vectors massively reduced.

Also if doing processing on requests Exchanges using for hot wallets could check nobody ever moves more than X btc, or than an amount martches a verified withdrawl in another DB or cache..

Basically youd never run bitcoind on an exposed linux machine, all would be via unikernel tcp stack.

Thoughts appreciated.

Hey,

The idea of a decentralized marketplace, embedded into a bitcoin-like blockchain has been something thats crossed my mind a few times since i first heard about anonymous Tor marketplaces a couple of years ago.

So this is very interesting to me. Could you post or PM me some more details on your implementation?

Thanks

Just to be clear i was in no way complaining! I was just checking that I had understood things properly and that i wasnt doing anything wrong and loosing shares!

Are you running MySQL inside a traditional amazon EC2 compute instance? Or are you using the Amazon Relational Database Service? http://aws.amazon.com/rds/

I have been mining with this pool through 3+ blocks now and my BTC balance is still at 0BTC despite having submitted 100's or 1000's of shares in each of these 3+ rounds.

Is this just slow database?

So the 0.00003030 BTC/share is not valid if signing up and starting today?

~600MH/s pointed your way since about 9am GMT today.

Im assuming the top balances only update when a block is found even for PPS?

Having used a number of different registrars web control panels I know some of them can be quite illogical and mistakes like this can be easy to make the first time you use them.

Once the nameservers hit the WHOIS DB and resolvers around the world start caching queries you have yourself several hours of problems.

Andy

The IPS tag was changed, the new destination registrar inserted its default nameservers for the domain which were:


these servers were serving up: 69.64.147.243 as the A record for britcoin.co.uk

And then a few moments ago the WHOIS output shows the DNS servers have again changed to:


These servers are responding with:


So once DNS caches have expired the site will work normally. The hosts file fudge i posted previously will work in the meantime if you still see the parking page.

Andy

genjix, thanks for the update.


When will it be possible to make a GBP Withdrawl again? I will hang fire making any such requests until it wont cause any problems.

Thanks

Andy

Adding the following to /etc/hosts (or windows\system32\drivers\etc\hosts or somesuch on windoze) gets access to the site and OpenID works fine for me


Everything works as expected once logged in with a fudged entry in my Hosts file - so all transactions etc are not lost.

This looks to me like the domain has been hijacked?

Andy

Apologies for posting this to this thread but webmaster@britcoin.co.uk bounced my message back to me.

Firstly, excellent site/service. I am very impressed. Over 48 Hours ago i submitted my first withdrawl request and it is still Verifying. Have i missed something? Is there anything else i need to do?

withdrawl Request 1914

I hope i am not being premature in enquiring about the status of this request!

Many thanks

Andy

FYI the webmaster@britcoin.co.uk address bounced the message with:
 

Hey,

work on the ISO lost the battle with my 3.5yr old for my attention this weekend!

I will have time tonight and tomorrow to integrate the ATI stuff, and should have a 5870 arriving on tuesday to test it and improve things myself.

Andy

Thanks for the info, ill get that integrated and post a new ISO for someone with an ATI GPU to test.

Andy

Hey,

Right, here is a version of the live ISO ive been using for mining.

http://emphony.com/UbuntuLiveMiner.iso

The actual version i use has an entry in /etc/rc.local which automatically kicks off the python GPU miner and minerd in a screen session, but this has had to be removed as it had my Deepbit account credentials in the parameters. So you will have to kick off these processes manually. An SSH Daemon will start on boot so you can do this remotely if desired.

root password = bcroot1

Python GPU miner and some other bits are in /mining

cpu miner is at /usr/bin/minerd

As root (or sudo) you can

Tested fine with on a few systems Nvidia cards - and also on some PCs with no GPU (just cpu mining)

I dont have any ATI hardware, so im not sure if the stock drivers are any good for gpu mining. If not and someone can give me an idea of what extra needs installing i will happily integrate the ATI drivers and any other software for them to test.

Any issues/requests/etc just let me know.

Andy

I'm about to head to bed but ill upload it first thing and post the link in this thread.

Hi,

I have a large number of pcs at my disposal that I can use for mining on an evening, but can't touch the HDDs, so I've rolled a custom ubuntu 10.10 ISO with jkzaliks CPU miner and the python openCL GPU miner ready to run.

I PXE boot it but it burns to cd or dvd or usb fine too. If anyone is interested ill upload the ISO somewhere to share.

Andy
