A token from some other technology. When I write a check with 10 XMR to someone else and the bank has those 10 XMR on my my account, the check is the token until redeemed by the bank. This really isn't difficult to understand, yet the maxis completely refute reality like a religion instead of facts. Doesn't matter if my check has a "smart contract" with the bank. In the end of day it isn't the same as the original currency and nobody here should ever lose sight of that basic fact.
