The 4 gems Satoshi used that gave life to #bitcoin:

Public-key cryptography: a system of secure data exchange first described publicly in the late 1970s. This allowed for the signing and digital confirmation of a property of information.

HASH-based secure identifiers: the first generation of which was also implemented in the late 1970s. This allowed the creation of verifiable summaries of information.

Peer-to-peer networks: a way of connecting computers that came to public attention in the late 1990s through the file sharing service Napster. Which allowed point to point, unmediated information to be transmitted.

Proof-of-work: a spam remedy, first described in 1997, that allowed effort (energy) to be required to send information.

now add a source of information without the possibility of blocking nostr.

and we have something better than the meta universe.)
