Protocol Design Is Policy-Making, and Crypto Should Demand Better Governance

Despite using crypto wallets for almost a decade, just a few weeks ago I fell for a scam. Many times, I have made some kind of error on a transaction. Ledgers are immutable, but transactions need not be. Any contract worth trusting should be able to reverse transactions that can be proven erroneous or fraudulent. Reversible tokens exist and should be used far more widely, particularly for consumer applications. Combined with clear policies and adjudication, restitution is a requirement for any system that humans are expected to use.
