This question already has an answer here:

What additional advantages would a multi signature address give?

Can it create multiple nodes for blockchain broadcasting?

  • @TaylorGerring Pl read the question completely. I don't think both of them are duplicates of each other :) – Dawny33 Jan 20 '16 at 18:11
  • Thanks @Dawny33, I do agree they're not exactly the same, however I address how "multisignature" addresses differ between Bitcoin and Ethereum in the linked duplciate. Strictly speaking, "multisignature" is a Bitcoin concept not directly translatable to Ethereum, thus making the question a bit nonsensical. – Taylor Gerring Jan 20 '16 at 18:14
  • In its current form I agree that this question is already answered in the linked duplicate. If it can be changed to make it genuinely different we can always vote to reopen. – Jeff Coleman Jan 20 '16 at 23:46

Multisignature in the bitcoin sense would typically mean you need n-of-m private keys to sign a transaction to make it valid. https://en.bitcoin.it/wiki/Multisignature

In the Ethereum sense, Multisignature can mean anything. From the Ethereum Wallet (Mist): "This is a joint wallet controlled by 3 owners. You can send up to 100 ether per day. Any transaction over that daily limit requires the confirmation of 2 owners." (After this, you enter the Owner Addresses. Bold values are editable in the gui.)

That is just the default multisig contract in Ethereum Wallet (Mist), but you can make a contract that has any arbitrary logic if you have the programming knowledge.

AFAIK there is no native multisig address mechanism in Ethereum. Multisig in Ethereum terms is a simple smart contract that checks all necessary signatures and if conditions defined by a contract are met the contract release funds. Please follow this example to understand how that works.
