Is bitcoin.de down? All I get are endless cloudflare CAPCHA's.

EDIT: Wow, I had no idea cloudflare could be so annoying.

I really want a Nokia X android phone but Nokia have no plans to sell them in my region.

If anyone can get their hands on a real Nokia X (or maybe X+) can you let me know how much you want for it plus tracked shipping to Europe? It has to be not locked to any specific network and still in sealed packaging.

I'm a little confused about the transaction inputs the bitcoin client used in a transaction I made. Can someone explain transaction 20739340da0db8b694994b1d9d4608d00b1ad1b2739c57b40973a2f63df54c07 ?

This is me sending 0.025 bitcoins to someone from my wallet. The inputs puzzle me.

2 Inputs:
0.0290498 BTC
0.01054802 BTC.
2 outputs:
0.025 BTC -my desired output
0.01409782 BTC -my change
Transaction fee - 0.0005 BTC

Why did the bitcoin client use the 0.01054802 BTC input at all? It could have just used the 0.0290498 BTC input which would have covered my output, the transaction fee, and left change. Is this something to do with prioritizing old coins?

I keep seeing instances of people confusing JavaScript with Java. They sound the same but they are totally different languages used for different things.

Web browsers would normally run Javascript. They would rarely run Java. If you ever get a pop-up claiming you should run a Java applet be very suspicious.


If you already know this please don't flame me.

I think bitbargain.co.uk deserve a mention. They don't appear to be scammers as such but they do have a market setup with a very limited pool of sellers who are charging 10% to 25% over mtgox prices for BTC. Apparently they hand pick the sellers seemingly to keep the number down to themselves and their friends. This allows the sellers to make excessive profits by simply buying coins on GOX and reselling on bitbargain.

I have 3 bitcoin related domain names I want to sell. These are all registered until the middle of 2022.

mountbtc.com
mount-btc.com
stackcoinica.com


If you want any of these please message me with your best offer. Payment in BTC, I'm happy to use escrow.

I have a fully working HD5870 up for sale on bitmit:

https://www.bitmit.net/en/trade/i/8346-hd5870-gpu

Starting price 0.5BTC, buy it now at 8 BTC. Get yourself a bargain.


EDITED:
Link updated for new action of a different, identical spec card.

This looks like a rather good deal right now:
https://www.bitmit.net/en/trade/i/5142-685-euro-by-sepa-anywhere-within-europe/description

Or I'm buying by SEPA EUR transfer for 6.90 EUR each. That's slightly better than the deal above as I don't have to pay bitmit fees.


Offers may be changed in the case of big market movements but once I agree to a deal I consider it a contract and will follow it though even if it costs me money.

What's the most pragmatic way to get information on a given transaction? For a transaction ID I'd like to know how much and from which addresses BTC was sent, and how much and to which addresses it was sent to. This should include transactions that have not made their way into the block chain yet.

I'd rather not rely on an external service like a block explorer. Running my own seems like overkill but it's an option. I noticed ABE doesn't tell me about uncommitted transactions anyway. The standard client seems limited in the information it gives out. i.e. it won't tell me the address bitcoins sent to me are sent from and won't tell me anything about transactions I'm not involved in.

Bidding starting at 0.50 BTC. Get in there and get a bargain.

I'd like to buy BitCoins for EUR paid by a SEPA transfer.

I'll pay the mtgox weighted average converted to EUR on xe.com plus 2%. The weighted average is shown on the top of the mtgox login screen, you don't need to login to see this.

For example if current weighted average is 9.00 USD = 7.40 EUR + 2% = 7.54 EUR per BitCoin.


Procedure:

Send me a PM here telling me how many BTC you want to sell.
I'll reply with a rate and the BitCoin address to send the BTC to.
If you are happy with the rate send the BTC to the address I gave.
I'll send you a SEPA transfer within one day, it should get anywhere within the SEPA region within a week.
I would be grateful if you would then post to this thread saying all went well. This is not mandatory but will help me build up a good reputation.

Minimum 1 BTC, Maximum 2000 EUR.

EDIT: Updated the exchange rate and reduced the minimum to 1 BTC in order to build up some trust here.

Anyone selling BitCoins for GBP, EUR, or PLN ?

Intersango appear to be changing banks ( again! ) and have blocked outgoing payments for a few weeks. That is good news for you because a lot of sellers have dropped out pushing the prices way up. If you want to sell your bitcoins for GBP, EUR, or PLN Intersango you will get a better price than anywhere else because of this.

The downside is you have to wait until July 26th-30th to get your transfer out. If you are not in a hurry you will get a better rate on Intersango.


Full disclosure - I have nothing to do with Intersango except as a customer. I want to buy BitCoins on Intersango as it's the only EUR exchange I can easily get money into. The rate is particularly bad for me right now since a lot of sellers dropped out.

If someone sells or sends me BTC what tools can I use to tell if they have been stolen?

Are there tools that can tell me what percentage of dirty coins I have in my wallet, or in any given address?


As MtGox is detecting and blocking transfers of stolen coins I assume these tools do exist somewhere.

Ok folks, we all know that SolidCoin is a scam. We all know it's written by a psycho who maintains an iron fist on the code, his IRC channel, and his forums. We all know this psycho has a massive premine and gets a huge amount of tax on every generated block. We all know SolidCoin is badly misdesigned and will fall over sooner or later. We all know that viper-lemon is this psycho's anal bitch-boy. We get it.

Can we all just stop commenting on the SolidCoin threads and let this con die off. At this stage anyone who gets involved in SolidCoin is either too dumb to read or is just looking for someone to rip them off.

Please can we just let it die?

Please?

In another locked thread maged asked:

What's stopping a single trusted node from being behind a proxy and only making outbound connections? Sure, you can DDoS the nodes that the trusted node is connected to, but the trusted node will be able to detect this and make new outbound connections. Essentially, to take down the network, you'd have to DDoS all of the listening nodes.

Now, you're probably going to say that you could do a sybil attack and just wait until the trusted node connects to you. But what if at least one trusted node is located behind a DDoS protection provider that will block and absorb all incoming connections?

To answer your first paragraph: There is nothing to stop a trusted node from being behind a proxy. Assuming that trusted node is still connecting to effectively random normal nodes that won't provide it any protection from attack. Assuming the attack we are talking about is a DDOS the proxy can be attacked instead, that will prevent the trusted node from communicating and freeze the chain. It doesn't make any difference that the proxy may only allow outgoing connections, it can still be DDOSed off the network. The only case where you would have to DDOS all the listening nodes is where the trusted node communicates with them and no-one else.

To answer your second paragraph: If the trusted node is behind some kind of DDOS protection whoever is doing the protecting would need available bandwidth in excess of the DDOS. That's likely if the DDOS is just a few instances of LOIC but it's highly unlikely if hit by the kind of botnets that have been hitting slush and deepbit recently. Maybe protection from those scale attacks exists but if it does it's going to cost a fortune. Few things have more bandwidth than an army of dumb windows machines on broadband.

SolidCoin 2 introduced critical design flaws. One of these is centralization. To stop a BitCoin network you would need to break every single BitCoin node. To stop SolidCoin you only need to break a handful of nodes. It's Broken As Designed and anyone using SolidCoin should be scared. Although we are talking about DDOS attacks above they are of course not the only thing that takes computers down. Hardware fails, electricity fails, sites have to be shutdown when water starts leaking from the aircon, SCSI cables and ethernet cables fail, the guy digging up the road outside slices though your fiber connection, operators pull the power plug from the wrong machine, the security people steal the disks from your machine at night, DNS people screwup, SAN people screwup, the network team freak out and cut your connection because of some stupid understanding and/or they are drunk after lunch each friday. Anything that can go wrong will at one time or another.

I have 693.22493928 I0Coins and would like some bitcoins for them. If anyone wants these post your I0Coin address and the amount of BTC you will give me for them. I don't expect serious offers but it's worth a shot.

I suggest moving the discussions of IO/IX/SolidCoin to their own child boards.

This will prevent this board becoming a ground for endless arguments for and against the existence of these currencies and will free this board to discuss new ideas.

[I'd like to introduce nullcoin - an alternative cryptocurrency]

I'd like to introduce nullcoin - an alternative cryptocurrency

Nullcoin has a number of advantages over bitcoin, these are:

* Instant transactions. There is no need to wait for 6 confirmations as all transactions are instant.

* Guaranteed stable exchange rates with IXCoin, IOCoin, and Solidcoin. Although not with bitcoin.

* Significantly lower electrical use due to the alternative way hashing is handled.

* Lower hardware requirements.

* A far fairer coin distribution method. No longer will the people who can sink the greatest amount of money into hardware get the most coins. Everything is fair and equal.

* A system that is literally impossible to game.

* Better security. Incidents like the mtgox hack, the mybitcoin hack, or the Bitomat loss will be quite impossible with nullcoin.


A quick FAQ:

How can I get rich really quick using nullcoin?

You can't, it's not designed like that.

Did you premine a whole load of coins like IXcoin?

Nope. Everyone has the chance to get the same.

How can you claim that you will maintain a stable exchange rate with IXCoin, IOCoin, and Solidcoin? That sounds impossible.

The exchange rates may vary for a short time but will always tend towards a stable rate. Complex mathematical modeling shows a 1 to 1 exchange rate with all 3 of the above currencies will develop over time. Sadly it's impossible to predict the exchange rate between Nullcoin and Bitcoin using the same methods.

What mining software does nullcoin use?

NullCoin does not use conventional compute heavy and power wasting mining software. The client handles all mining requirements.

What client software does nullcoin use?

Special null software that only runs when your system is powered off. In this way it saves significant electricity and ensures perfect security.

So it doesn't actually do anything then?

No. The clue is in the name.

Are you taking the piss?

Yes I am.

Why?

Because I'm started to get bored with people inventing new currencies every couple of days. They are transparent get rich quick schemes and won't work. Stop forking bitcoin, it's getting old already. We can live with bitcoin and namecoin, the rest of you bring something truly new or get out of town.
