The Real Constraint in Tokenization Is Scope, Not Technology
Tokenization succeeds or fails on scope, not technology. The issuance question is only about one-sixth of the work. Here's what disciplined scope actually covers, and why planning for optionality matters more than locking in today's assumptions.
