I do not see any real reason to use multi sig wallets. Especially for ordinary people. And BTC confirmation times can be for hours, so better choice is to use simple online wallet, like Blockchain.

I have been unable to think of any good reason why a single user would need or even want a 3xxxxx... wallet.
Kraken do.
Seems really logic in enterprise strategy of security ... you can't speend without muti-sig for valid spending.
no problem here.
only feature.

For regular people I think multi-sig has no real advantage, Unless for some reason you want to lock your coins, Other than that multisig has no serious use and merely just some extra bitcoin knowledge.

More security. If you had to sign transaction from key on your computer, then sign it from key on your phone attacker would need to compromise both devices. Something like 2 factor authentication

Multisig gives us very high security. The security is important. I use Copay wallet from Bitpay. The wallet has a user-friendly interface. Try it.

Is this service available currently or something you are thinking about working on,have not come across this idea yet reason I ask.
The escrow and maybe making purchases where you do not know or trust the other party.

It's nothing to do with me. I'm new to bitcoin.
It's the lightning network (https://lightning.network/) proposed by Poon and Dryja.
Transaction malleability needs to be fixed for it to work properly - which segwit will do, if it happens.

I dont think so, why would the average user sue multisig. i think it is prob something that we may all use further down the line once we see the benefit

I think that we all will be using multisig eventually.
Multisig is needed for payment channels, which currently seems to be the hot idea for making bitcoin scale.
The basic idea is that instead of broadcasting every transaction to the blockchain, one party will partially sign a transaction from a 2 of 2 multisig output which the other party keeps as security (knowing that they can sign it and get the coins if needed). Subsequently many more new transactions can be signed by one of the parties and stored by the other, representing a kind of floating balance between the two parties without ever broadcasting to the blockchain. Eventually a transaction is broadcast - settling up and closing the channel.
There are more details…

Using a multi-sig wallet may come in handy later on and being a single user is not a disadvantage of using such a wallet you just don't activate this feature.
March 14, 2016, 02:43:43 PM
I don't think so, As far as I know these are most appropriate for Services like middlemen/escrow, Wallets to ensure security of deposited funds and companies etc... I don't think it's useful in any specific way for a person unless it's to control a gambling addiction or some rather different situation.

For a single person not having huge balances... I think there is no real or practical reason unless it's a company or a group of people not wanting to trust each other... so I would consider this just interesting for regular people with no practical use.

If there is only single user then I don't see the need for using them but some people do it because it adds another layer of protection, like with Copay, you can have yourself as a co-signee on your phone. If you need one, you can use electrum.
Yes, you can essentially make your wallet 2fa without risk that the service provider can run with your coins.
the 1st set of keys is with your hot wallet
the 2nd set of keys is with the service (e.g. copay)
the 3rd set of keys is in your (offline) secure backup
Any 2 can sign. So if your hot wallet is compromised, the attacker would also need your phone (for one key from the 2nd set) or your secure backup (for one key from the 3rd set). If the service is no longer availalbe you can move the funds yourself with your hot wallet and your secure backup.

If you want someone to co-sign your transactions for some or other reason, you use multi-sig ... I on the other hand, do not want to make it too complex, because this adds various extra variables to the scenario, if you
go this route. Questions on availability of co-signers ect, and if something happens to them, will always be a issue. You will find that the advantage of doing it in this way and the added security it brings, might just not
out weigh the troubles you might have in future, if something goes wrong.

they also occupy more space on the block, so they are a part of the reason why there is the ned of an increase in the limit, minor part but existing
i've only seen this used in some exchange and some services for funds release it's good, when more than one party is in control of the money

They happen so rarely I doubt they have a significant impact on the block size issue.
I do think a bigger block will be needed soon, SegWit may help but I still think needed soon, but I think the block size debate is being blown way out of proportion.
We'll see what happens after SegWit.

The only other reason I can think of is if you want to use the wallet for some type of escrow service where you need at least 2 private keys to access the funds. This would ensure that the transaction is more secure and that any dispute can be resolved effectively.

A 75% fee discount on signature space when we wake up one morning to see that Seg Wit Soft Fork has been approved by 4 Chinese/1 Georgian dude, and 80% of the node network has entered part zombie status.

And who's using it now? And for what?
I did generate one previously. Just one question: is there any software to help with vanity address for 3xxx keys?
