To reply to my own topic:

blockexplorer seem to use this branch
https://github.com/jgarzik/bitcoin

but it seem to be unmantained.

I want to be able to look at other transactions not in my wallet ("non-wallet" as bitcoind calls them).

I found out it's not possible using bitcoind. It is possible to call external API, but I don't want to do that since I will be doing it in bigger numbers and I don't want to spam other services.

Is it possible somehow using either bitcoind or some other tools?

Hm. By comparing this pull request

https://github.com/bitcoin/bitcoin/pull/886/files

and comparing it to the code here

https://github.com/bitcoin/bitcoin/blob/master/src/bitcoinrps.cpp
https://github.com/bitcoin/bitcoin/blob/master/src/rpcblockchain.cpp

it seems like it is NOT possible today. Oh well. I will do it on transaction-by-transaction basis. (I wanted to use Blockchain.info API but they are mysteriously missing some blocks from their API results. Oh well.)

Hello.

I stumbled on this old thread while researching about bitcoind.

Is the decomposition with getblock possible in the newest (0.8.1) bitcoind? And if it is, how? (Your options return just errors.)

By manually editing the install file and switching it to 1.6.2 I installed the old version and that one works fine.

So it is something in the 1.7.1.

I have tried the lastest version (1.7.1). It starts all right, but then crashes when signing transactions, no matter what.

I will try to download old versions somehow.

it's funny how the same people talk about how bitcoin will take over the world and take over all transactions... and then they are angry at business that *uses it too much*... I mean come on. Free market and all that jazz!

SD is in my opinion not a spam. They are sending clearly distinguishable transactions, not trying to mask it or anything, and the miners can decide what to do with it.

When I look at it, some people dumped 2 nonsensical junk files, me and some other guy wrote something in plaintext and that's about it. So nothing important happened there.

You need seeders for magnets, though.

I still haven't sorted out what to do when some of the file parts expires.

It is possible to look at even expired domains, but I am not sure how.

AFAIK, namecoin can be used as general persistent key/value storage. (It is even encouraged on the wiki - http://dot-bit.org/Use_cases )

If it can be used as such, it can be used to store files, too, if they are encoded correctly.

If miners won't want to accept these transactions they won't. Free market and so on.

not really, first you cannot sava arbitrary data to bitcoin transactions (in theory you can, but the nodes will not relay it, so you can't). Also, there is some anti-spamming protection in bitcoin client. And lastly, miners can just ignore the requests if the fees are low enough.

Which will probably happen anyway with namecoin if my way of saving files becomes popular. (people in general don't like illegal data on their disks. also it does not scale at all.)

I am thinking of making some simple GUI to this, though. It is still too complicated with the need to run namecoind from bash and so on

well right now the only things there are my experiments so no need to panic

I found a way to save any arbitrary files to namecoin blockchain.

I think this can be kind of big.

Hello,

I would like to install Android version on my tablet. If I go to the website, it tells me to scan some QR codes. I can't print from my Android tablet so I can't scan the QR code in any way.

I would prefer just clicking and writing something somewhere. (Or, better yet, just going into Play Store and just installing it, but that's just a dream.)

Hello,

I have a question. Are there any public lists of IP addresses of big miners/mining pools? Not their websites, but really IP addresses of servers, from which they mine and to which I can connect with BitCoin protocol.

Why am I asking? I am developing an application, that will have non-standard scripts in output signatures. However, regular bitcoin clients refuse to relay those for some reason. So, I would like to add IP addresses of the known big miners as first peers to my application, since there is bigger chance that they will accept it and add it to blockchain.

And what leads me for thinking there might be a list of IP addresses? There are graphs of miners shares on blockchain.info; they must identify the miners somehow.

Pywallet imports the wallet into the "official" bitcoin client wallet.dat format, right?

Without importing the keys somewhere, the bitcoins are quite useless since you can't really post them anywhere.

This is awesome. I am not sure if I like the strange wallet generation and the fact that I can't import my own wallet.dat, but other than that, I really like this.


How does the paper-based wallet work? More exactly - I know I can check the balance on, say, block explorer, but how do I send the bitcoins to someone when I have the private key?

And another, more "philosophical" question.

A lot of you guys are thinking BitCoin will be the currency of the future. Do you really expect people to wait hours and hours before the blockchain downloads? (Not everyone can find the blockchain hidden in sourceforge plus run the client with '-rescan' option.)

Plus, if it really takes off, the blockchains will be even bigger and the waiting times astronomical (and I can't imagine how big the whole blockchain will be). Even today, I am starting to think why I haven't just used PayPal, it would be less anonymous, but I would have the money right now. It will be totally unusable if the currency is to used by a bigger circle of people.

Hello.

I think I do understand inner BitCoin workings a bit, but one thing bothers me, even as a "simple" user.

I want to receive a payment. I haven't opened BitCoin application in about 3 months. So, I open the application, expecting the payment in few minutes.

...but I have to wait hours and hours and hours, while the client downloads the last 10 000 blocks slooooowwwwllyyyy.... one... by .... one. (Eating huge chunks of RAM and CPU as a byproduct, but I guess that has more to do with my aging computer.)

Do I have any alternative? Like, say, don't download the blockchain from the deadslow P2P network, but from some "trusted" place like blockexplorer?

Yes, I know I can use some online bitcoin wallet, but that didn't work out so well with MyBitcoin, right.

edit:

Aah. Right now, I discovered this:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/

It seems about allright, but why is there "may" in quotes? Shouldn't the -rescan option just work?

edit2:
no it doesn't. The linked blockchain is ancient. Oh well, another few hours of downloading.
