May I ask why the 80-Bytes limit?
The Bitcoin protocol was designed to engulf the whole world, to be a planetary coin, and iXcoin is identical.
Bitcoin due to how much money that is involved, will be extremely conservative in adding new features. In fact, the current thinking is that new capabilities are to be introduced using side-chains and secured by merge mining.
Innovation will happen at the edges and not at the core.
Wow, what bullshit.
This gives IXC a MASSIVE window of opportunity to literally supass bitcoin in features and security.
Instinct tells me security "on the edges" (side chains) will not be the same as at the core.
Why mess with that, it could pose seriou unkown threats. IXC can do it the right way and if we can do it properly with counterparty then the rest will come to us.
