Coin.bin is a fantastic set of tools.
I am not familiar with javacript or crypto to start changing things but how do I set this to use testnet addresses,
I would guess it has to do with x.unshift being set to 0x11
Is that correct?

OutCast3k, congrats on the release! We talked about it awhile ago on IRC, I'm glad to see you released it.
It doesn't do the same thing; Coinb.in has a general purpose tool that can be used for many kinds of multi-signature transactions, while Bitrated was created specifically to facilitate arbitration services and has an interface that was optimized for that purpose. Also, Bitrated does not require setting up an account - its optional and only for arbitrators that wants to be listed on the website, and buyers/sellers don't have accounts at all (and I believe it should be quite easy to use with something like bitmit).
Also you might want to look at http://www.bitrated.com/ which does the same thing but requires an account and has some other features. I don't think it can be easily used with an online auction site, like bitmit.net with multisigs. Your site seems much better for that.

Thanks for the correction. Sorry about the misinformation.

1. If the public key is copied in with a mistake it could lead to loss of funds. Perhaps we need a standard for base58check public keys? According to the wiki (https://en.bitcoin.it/wiki/Base58Check_encoding#Version_bytes) you'd use the version byte 42 but it's marked "proposed" and I can't find any other info on it.
Added a check to make sure public keys are valid
Also, looking to also re-brand it from "escrow" to something else, any suggestions are welcome.

Very good. Allows use of multisigs without installing bitcoin-qt and downloading the blockchain.
However you shouldn't use the word "escrow" to describe this. This isn't escrow because the escrow agent cannot run off with the money. Also "escrow" agents are heavily regulated in many parts of the world, while arbitrators, adjudicators, mediators, judges, reconcilers, referees, umpires, etc are not subject to that regulation.
Changing the word doesn't change much in law, but its bad to give the wrong idea to lawyers since multisig transactions are not something that's ever existed before to my knowledge.

Good point on the terminology, you're right, "escrow" probably isn't the right term. I'll have a think about what to change it to, but I am open to suggestions..
Also I agree I should validate the public keys, to prevent loss of funds, I'll try and come up with something later today.
Thanks for the feedback

This is fantastic!
I will be testing this in the coming days and will provide some feedback. Keep up the good work.

Couple of small updates made, will upload to github later
December 29, 2013, 08:05:55 AM
this is great! keep up the good work.
* I think it would great to explain the process and concepts in more detail on the site. What is a redeem script?
* say I want to implement the following: pay 0.01 BTC to address #A12 if the year in the timestamp of the last block is equal to 2014. what would it take to make this work?
* btw, the link on the site to your profile is broken. I think you want this: https://bitcointalksearch.org/user/outcast3k-34834

You're right, I will defiantly add more information to the site about the process shortly.
A "redeem script" contains 2 pieces of information, the public keys and the minimum number of signatures required to use it as a spendable input. It is also used to generate the multi signature address itself. There should be some information on the bitcoin wiki about this, but I will also add it to the site shortly.
I believe its possible to manipulate the timestamp of the transaction in the way you've requested, although I will need to do a little bit of testing first.
Thanks for pointing out the broken link, I've since fixed it.

Whilst bitescrow.org is pretty neat, unless I'm mistaken it seems to use a different method to facilitate an escrow, it does not seem to use multi signature addresses and is limited to the number of parties that can take part.
What I have developed allows for true multi signature addresses to created in within your browser, and all the outputs are compatible with bitcoin-qt.
To clarify, a multi signature address starts with a 3, like this address 39wJtGk78E76AKpUKLhzrhmwVyZZHfCUbV it does not start with a 1 like normal addresses.
