What;'s your price ?

Do you have a link for some API docs ?

Hi. Onchain.io has support for signing transactions via QR codes.

You can see the code and some screenshots of the app here. https://github.com/onchain/onchain-android

It would be good if the BIP followed the existing protocol.

Let me know what you think.

Dark Wallet supports BitID ? Do you have a link I can look at.

Not sure. It's working now, that's the main thing.

OK, thanks. Seems to be working now.

That's correct.


I'll do some extra debug now. Thanks.

OK. I've deployed the latest onchain.io app with Bit ID support to the play store.

I still have the issue above but it will have to wait.  If anyone has some feedback for me on this, that would be great.

Hi, I'm working on an android app at the moment. I can log onto erics implementation (ruby on rails app) but not yours.

I think this may be a confusion over the protocol. I'm posting the following parameters.

I'm gathering feedback for a new multi sig wallet here http://www.reddit.com/r/Bitcoin/comments/2em98m/onchainio_a_real_online_multi_sig_wallet_feedback/

I'd be grateful for anyone that joins the discussion and helps to shape a future wallet.

Thanks.

Hi BarkinTree,

I'm also starting a business in the bitcoin space and will be blogging my efforts. You can see here https://www.onchain.io/blog

I also recommend http://www.craftsmanfounder.com/ and http://www.softwarebyrob.com/

I will say, Bitcoin is a great place to start as people are eager for solutions and their are plenty of problems to fix.

I wouldn't keep a private key with the application.

You could certainly have an application that creates Bitcoin transactions, that another service could then sign.

Have you taken a look at BitcoinJ ? You can configure it to use a SQL database via JDBC.

That's not exactly what was said, or perhaps I'm mistaken. I think Vitalik mentioned that he would like to see code or a paper on the NXT solution (Economic Certainty) which is as far as I understand it a proposal at the moment.

There's some very clever stuff happening with NXT but at the moment there is also an air of mystery around potential solutions to the nothing at stake problem.

p.s. I hold NXT and BTC, nothing else.

I think having a solution that required several proof of work algorithms, i.e. one is selected somewhat randomly based on the last block might be the way to go.

A general CPU would be good for this task.

iphone solution is in the pieline.

Collaboration between an escrow agent and the buyer or seller is always a risk. So reputation is important for an escrow agent, however with using multi sig it's easier to build a reputation, because your using the right tools int he first place.

Probably the best thing to do is set up some example escrows.

For anyone interested PM me with 2 example email addresses you have access to, one of a buyer one of a seller. I'll create an escrow agreement.

When the agreement is created in onchain it will send out the invites to the 2 addresses ( and also to to me as I'll act as an escrow agent).

You can then see how the multi sig creation stuff works. I'll fund the bitcoins

You can eliminate spent outputs yes. It's generally called blockchain pruning and there have been several discussion on this. i.e. https://bitcointalk.org/index.php?topic=96644.0

Enjoy.

onchain.io is trustless because we are creating genuine multi sig contracts. Only if 2 participants agree can the Bitcoins be spent. As an escrow agent you would not have access to the funds so participants only need to trust that you will mediate correctly.

Here's a presentation about how it all works for escrow.

One issue I can see unless I've misunderstood.

When the winning block on the Bitcoin network is published, what's stopping me picking that up and publishing it onto the sidechain, even if I didn't mine it.
