Blockchain technology presents opportunities for dissonant opinions, fractionalization and internal reform unmatched in the fiat world.
Join hosts Jonathan Mohan, Stephanie Murphy and Andreas M. Antonopoulos as they dissect “Voice and Exit,” or the power and necessity of being able to impact a system, whether financial, social or governmental, and if necessary, leave altogether. “Voice and Exit” was popularized by Balaji Srinivasan in 2013, where Srinivasan outlined how voice is attempting to change a system from within, while exit is leaving to create a new one.
Crypto has provided new methods to exercise voice and exit. Forks, software or protocol changes that users can choose to upgrade to, are an example of exit inherent to blockchain technology. Forks give the community a chance to decide whether to continue with the upgrade or remain in the old rules; forks have created spin-off currencies like Bitcoin Cash and Bitcoin SV.
As opportunities for voice and exit seem to be gradually disappearing, can crypto help those who need them most?
