Something can be considered a hyperstructure if it is:
Unstoppable: the protocol cannot be stopped by anyone. It runs for as long as the underlying blockchain exists.
Free: there is a 0% protocol wide fee and runs exactly at gas cost.
Valuable: accrues value which is accessible and exitable by the owners.
Expansive: there are built-in incentives for participants in the protocol.
Permissionless: universally accessible and censorship resistant. Builders and users cannot be deplatformed.
Positive sum: it creates a win-win environment for participants to utilize the same infrastrastructure.
Credibly neutral: the protocol is user-agnostic.
