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't do it properly with counterparty then the rest will come to us.
It is not bullshit... it is reality... the bigger you get the more conservative you become.
Bitcoin will be at the core of the main use case... money transfer.
Then at the periphery you got all kinds of other stuff:
(1) Namecoins - i.e. registries.
(2) Distributed exchanges -
(3) Custom assets
etc.
So I doubt you'll ever see major upgrades to the Bitcoin core.
