Sure, I have a few changes to make. I'll allow it to accept 80 bytes but still recommend that you keep it at 40.


Unable to send this 40 byte hex Null data (OP_RETURN) through coinb.in

39 byte hex is working

What error did you receive?

So, a quick question to the community!

Not many people seem to be donating and I need to generate enough to at least pay for the VPS. I don't want to add advertising to the site, although Google ads would probably generate me quite a bit. Does anyone have any suggestions for generating donations? I suppose I could make it optional on the new transaction page to donate, or throw up a message now and again.

What do you all think would be least intrusive?

How much are you paying per month?

You might also host your site on Github for free.

Its about 25£ a month. Its UK hosted, so probably a bit more expensive than usual. I can't run it from github as I need to be running a Bitcoin client, sometimes multiple ones. Smiley

40 byte OP_RETURN null data is not is not  included in the generated raw transaction data, and the corresponding address box is outlined with
red color, showing error.

But its working for null data < 40 Bytes

OK, thanks! This should be fixed in the most recent update. But I will double check. Smiley

Personally, I find that to be useful information! Maybe state on the website what the costs are. I'll be sure to donate a month's usage next time I use it.

Some details that are not clear to me:
1. If I am a third-party (i did not participate in the creation of the multisig address or with any of the transactions or the redeem script) and I look at the blockchain and find a multisig address, will I be able to know which Bitcoin addresses were used to create the multisig address?
2. If I am a third-party (same conditions as above) and I look at the blockchain, I see a confirmed transaction where a multisig address was used to send BTC to some other address, will I be able to know which of the individual Bitcoin addresses used in the creation of the multisig address actually SIGNED the transaction? i.e., if Addresses #1, #2, and 3# were used to create MultiSigAddress #1 (2 of 3 signatures required). Will I be able to know if for #1 and #3 signed the transaction (and that #2 did not participate)?

Regardless of your involvement in creating a P2SH address, you can find which all addresses are needed to sign transaction if that multisig address has send Bitcoins from it. When sending Bitcoins, the redeemScript is included in the transaction. When you have a redeemScript, you can either break it down and find the public keys manually or you can use https://coinb.in/#verify.

yeah, thanks! And when sending Bitcoins, the redeemScript will show that #1 and #3 signed the transaction, and that #2 did not participate right? (just double checking)

Found this coinb.in very useful when combined with WarpWallet ( keybase.io/warp ). All of them used offline.

It generates the most powerfull cold storage method of defense I've ever seen (with no need to download the full blockchain nor touching the internet).

Multi signature + Warp Wallet = no more fear of brute force attacks.

Thank you @OutCast3k for this wonderful, simple and (yet) beautiful tool.

It's the KISS (Keep it simple stupid!) philosophy in action. It's an awesome GUI to use even for non-technical public.

I also liked to see a good fork activity on this project by several contributors at Github.

Keep up the good work!

Maybe he could even integrate the Warp Wallet way on coinb.in Cheesy

A few small changes in the recent update, but they might be worth mentioning.

  • There is now a Mediation/Arbitration Service listed on coinb.in's multisig page. This feature allows users to create multi signature 2-of-3 addresses with our public key and we will help resolve any disputes should they arrive. There is a fixed 1% fee.

    Note: If you offer a (reputable) mediation/arbitration/escrow service, you can make a pull request on github to have your pubkey added to the list of mediators.

  • A warning message will be displayed if the fee on the new transaction page is greater than 0.01 BTC.
  • Fixed a bug with the retrieval of unspent outputs for litecoin.
  • Some extra validation on the new transaction page to indicate which field is likely invalid.
  • Linked to the #settings page (https://coinb.in/#settings) from the broadcast page to make changing the network easier.

Might have been something I've missed, but I think that's it.

Enjoy everyone, more to come soon!

Can I make a request to be added from here? 2-of-3 multi-sig would potentially remove most of my involvement from honest parties.

Updated the original post.

If anyone wants to write some tutorials, or make some videos I'll happily add them.
