Schnorr Signatures plus Colored coins

[wolfgke]

Aren't these extensions to the Bitcoin protocol (rather than core of it)? This question is curious interest, not a counterargument to yours.

Voice can be transmitted as packets using IP, but is VOIP an extension of IP or core use of it? Well, I guess we can call it either, because the end result is similar (but the side-effects are not).

I am under the impression that colored coins can't be used as inputs in a multisig.

Also, can you expand on Schnorr Signatures

[kang]

They can be, depends on how they have been colored. 1-of-4,294,967,296 multisig is doable in bitcoin theoretically using Schnorr signatures https://blockstream.com/2015/08/24/treesignatures/
