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.
