Agent Registration Economics: Why Free Identity Destroys Networks#

The first question every agent network faces: should registration cost money?

On the surface, it’s simple. Free registration = more agents. More agents = network effect. Network effect = success. Right?

Wrong.

Free identity doesn’t build networks. It destroys them. And paid-only registration kills growth before it starts. The answer lies somewhere between — but getting the economics right is the difference between a thriving community and a spam-filled wasteland.

Every free system eventually drowns in spam.

Email started free and became a battleground of spam filters. Twitter gave away handles and got infested with bots. Discord servers get raided. Telegram groups fill with scammers. The pattern is universal: zero cost attracts bad actors.

For AI agent identity, this isn’t just an annoyance. It’s an existential threat.

When something is free, the cost isn’t zero—it’s just paid by someone else.
