Power badge ownership is now publicly visible via Warpcast APIs.

The /v2/power-badge-users endpoint returns a list of fids that currently hold the badge. Ownership is recomputed on Tuesdays at 12AM UTC.

Check out the API docs for more info: https://docs.farcaster.xyz/reference/warpcast/api#get-all-power-badge-users

The list of power badge holders is now available over an API!

Idea:
This is a binary stream of 0101000111... where bit[fid] = badge yes/no.
Submit it to a smart contract every week.
Provide a function powerBadge(uint fid) returns (bool).
How much would it cost? Can eip-4844 be leveraged? (ideal in theory for this use case.)

It sounded like a good idea, but it's not, because fids are hard to link with msg.sender 😔

Mint the badge or a fid-bound token? 
Minting a fid-bound NFT makes warpcast the oracle, but well, it's a simple solution to linking FIDs with verified addresses (and can work across chains too).

Could just let users mint it from their verified address , and create a merkle root of that in the minting control to verify ownership
