Farcaster

1/ Farcaster is permissionless. 

Anyone or anything can pay $3 worth of ETH to the smart contract on OP Mainnet to create an account.

After 1 year, the account has to pay $3 again to keep using the protocol.

There will be low quality stuff on the protocol! Just like the web and email.

Clients will solve quality.

The official account for Airstack, developer of @moxie-protocol. airstack.xyz. On a mission to grow the Farcaster GDP.

2/ If you're looking for a more moderated approach to the underlying protocol, check out federated protocols like ActivityPub or AT Proto.

Developer infra like @airstack.eth and @neynar are taking independent approaches to measuring quality. 

This is good for the protocol long term. You don't want a single spam algo.
