Another tool to learn about multisig and manually create multisig addresses or spend their outputs (and I think it can even be used offline) is http://coinb.in

If you want a multisig wallet that just works, your best bet right now is probably GreenAddress where you can get a 2of2 wallet recoverable by nLocktime transactions in case they ever disappear and optionally a 2of3 wallet recoverable manually (maybe through something like coinb.in).

Electrum would be another good choice, but then you have to manage all the keys yourself and it's only really secure if you have an offline computer for signing (and in that case, it's easier to just set up a watch-only wallet online and keep the seed offline). I haven't really done much with Armory, but I hear it comes highly recommended by those who have used it.

Yes, you can create multisig [1-of-1] of [2-of-2] or [m-of-n] address in your client
Use createmultisig and addmultisigaddress in rpc console

It's worth noting, make sure you completely read and understand how to create multisig addresses and spend from them using raw transactions before you put any of your coins in a multisig address.


Hello,

The following guide describes everything in details:
 
http://www.soroushjp.com/2014/12/20/bitcoin-multisig-the-hard-way-understanding-raw-multisignature-bitcoin-transactions/

You may start reading from "Creating a 2-of-3 multisig P2SH address..."

That link is not a very good approach to get started with multisig, it's overly complicated. It's much easier to do it in the bitcoin core/bitcoinQT console.

Here's a video that shows you how to do it if you're more of a visual learner.

Nice. James D'Angelo of World Bitcoin Network also has some great introductions (for visual learners): https://www.youtube.com/watch?v=zIbUSaZBJgU

Yes! D'Angelo does a great version too. He also added in a python script that makes the spending from the multisig easy.

If each key is signed independently, the user would have a lower chance to get hacked. The transaction will only be sent if x out of y slkeys are signed. This functions like a group of people holding a private key. The number of people agreeing to make the transaction must be more than x. Some people using this is some of the escrows and greenaddress.it .

Yes it's possible to create an address starting with a 3. Multisig addresses (created from various public keys) do exactly like this.

This may help you.

Use Armory Multisig* or Electrum Multisig or Bither Multisig.

Bither Multisig helps you to use your mobile as one of the device and signing and transmitting datas can be done via Qr code. So it is pretty much secure than using a USB stick or other CDs for transmitting datas from on computer to another for signing and broadcasting.

* Correct name "lockbox".

You can also create using Bitcoin Core with command posted by amaclin.

Can you actually create Bitcoin Adresses that start with a 3? Like: 3E1WpLsF2iMYxhtMZh9XE21bkf1Cp686e1 ?
They are actually valid and some websites have them.

For example Bit-X, they somehow all have deposit adresses starting with a 3.
So now comes the question: Am I able to create one for personal use and how/where can I do it. I dont want any webwallets, I want an adress with a private key for me.

Thanks in advance!
