Hey I'm still curious about the multisig abuse. Why would someone create a multisig address that nobody has the keys for, in essence locking those funds up forever? Are they just a nuisance (spam) or is there some kind of malicious intent I'm not seeing here?
Also how would you know if nobody has the keys for the multisig? Is there some kind of verification on your part? I don't how that would work.
For example, a 1-of-20 multisig where the first key is the real owner, and the other 19 are strings of data that can't even be valid keys.
They only need the 1 valid key to spend it later.
Last question then I'll drop it. What is the motivation? What is the point for the strings of "junk data". Are they just trying to embed spam type messages in the blockchain? Again forgive my lack of imagination here...
EDIT: This article answers some of the questions I have. I didn't even consider some of the uses talked about in the article such as:
Most controversial [are] things like Counterparty and Mastercoin, said Coinwalls Ortutay. They try to use the block chain as a datastore for various protocols, where things like bids/asks are embedded in bitcoin transactions.
http://www.coindesk.com/new-forms-spam-bloat-bitcoins-block-chain/I'm sure the use of blockchain type systems/technology is whatever people want it be but yes it would be better if they would use their own side chain to do their dirty work.
Ultimately it's up to the miners to decide what transactions they want to include in their blocks, so with that said I will be at the next discussion Elgius has about the pools policies.
Thanks for putting up with my curiosity.
