I have always wondered what they meant by that. Clicking on it gives some bunch of addresses and a "taint percentage". Is there any proper document explaining these terms?



I guess its been asked before. So please point me to the link.

Is there any work done on using the blockchain for public key certification/authentication, the job CAs currently do?

Bitcoin has challenged banks, the central authorities of money;
why not do the same to CAs, the centralized authorities of the Internet.

Namecoin does something close but we need a general way to map any domain name/email address to a public key (even a bitcoin address).

Please point me to any work done in this regard.

What are the main differences between the two versions?

Some I could immediately see: (in 0.12)

1. reformatted packages (com.google.bitcoin to org.bitcoinj)
2. support for multisigs
3. default private key is compressed

Are there any other?

With so many hacks recently, I wonder if some of them are related to reused r-values.
Is there a website where I can enter a "hacked address" and find out if any r-values were reused for that address?

I need a list of addresses that regularly receive and send bitcoins (say every 10 mins). I need it to test some notifiers I am building. Would be great to have some of them posted here.

Say someone deposits 10 BTC, with 6 confirmations and immediately places a sell. Someone else buys them and withdraws quickly.
After sometime a reorg invalidates the initial 10 BTC tx. What is the right way to handle this?

I'm guessing its going to swing either way at least 100. Anything in between is just ridiculous.

[Bitcoinmonitor.net]

I am making a list of services that provide payment notifications for watched bitcoin addresses; so I should give them addresses to watch and they should push a notifications to me when that address receives bitcoins. This is a very useful service for developers.

• Bitcoinmonitor.net The best one I found is http://www.bitcoinmonitor.net/ (shut-down)
• Blockchain.info websocket blockchain.info websocket API https://blockchain.info/api/api_websocket
• Biteasy.com biteasy websocket API (which is currently not working for me) https://support.biteasy.com/kb/websockets-api
• Blockonomics.co supports websocket notifications https://www.blockonomics.co/views/api.html
• Bitnotify Simple service that sends email notifications when payment is made. http://bitnotify.com/

Are there others? Lets make a list here.
I am looking especially at ones that use HTTP callback rather than via websocket.. something like bitcoinmonitor.net


EDIT: added suggestions by other posters (Have not tested all of them myself).

I don't know if this was posted before. At least, I could not find it using the "search".

Say you search for MtGox, looking for latest about MtGox, you will get pretty much everything *except* what you are looking for. Sometimes I think it has some sadistic intelligence and guesses what you need to give you something entirely different.

And what is this "relevance"? Doesn't make any sense.

There are a few bitcoin ATMs in Singapore. Has anyone used such an ATM?

I want to know how they work.

Say I want to buy bitcoins...

I know I have to give them banknotes, or maybe use my debit card (would be great if that's allowed)
Then what next?

Do I give them a bitcoin address (how?)
Or does it give me a preassigned address with the private key?

And finally, how is the rate decided?

This is definitely a wtf moment.

How can mtgox have "thought" that a wallet containing 200k was empty?

[pushtx]

I have used blockr.io and it is awesome! (as advanced as blockchain.info or more)
I have no hesitation recommending it.

Only thing it does not have is pushtx

blockexplorer.com is pretty primitive.

What else is there?

Who provides a pushtx?

I don't get it. Are they somehow connected. I guess, people smoke tobacco when drinking alcohol and those people also carry guns.. Or am I missing something here?

Since a few hours, blockchain.info has included "cloudflare DDoS protection".
This results in all API calls to fail.
I want to know if this will eventually be fixed (soon) or should we start looking at alternative API providers?

Lets say we have inputs A, B and outputs X, Y.

Say we have a tx = (Sign_A((A, B), (X, Y)), Sign_B((A, B), (X, Y)), (A, B), (X, Y))

What exactly is malleable here?

Please point me to the thread where this is explained.

https://blockchain.info/block-index/465621/0000000000000001349dfd45adba30c0f7aebb5c1ca4d079a167feeb7d63ab0d

contains no transactions except the newly generated coins. Why?

Hey proudhon, guess you forgot.. so pointing you to the original thread:

https://bitcointalk.org/index.php?topic=157693.0

In case others are wondering, I speculated in March that 1 BTC will hit 1000 USD before 2013 end. Proudhon said that he'll give me one BTC if it does (and it won't happen)/
Well it did cross 1000 USD in 2013, so I am owed 1 BTC.. would most people agree?

With the recent screwps.. Cyprus, Chase bank, etc. and so many new adopters, it looks like we will cross 1000 this year, a couple of years too soon in my opinion.. And im not complaining

I'll give OP a bitcoin if it hits $1000/BTC this year.  Will not happen.

Proudhon, hope you will be as good as your word.

Thanks in advance.

EDIT: Proudhon was true to his word. (Proudhon, hope you didn't mind my gentle remainder)

I am looking for altcoins having API providers similar to blockchain.info.

Specifically, the following functions are needed.

1. https://blockchain.info/pushtx (push a tx)
2. http://blockchain.info/rawaddr/ (get all transactions for an address)

Which altcoins have such an API?
