Personally I think so far, badges within the donuts system have not been used very much. The limitations on duration of ownership (1 month) I believe limits their appeal. The daonuts framework doesn't yet have a replacement for these centralised badges but that should actually be pretty straightforward to build. I'd like to do so in a way that maximises their potential. I'll just start by throwing out a few ideas and please join in with your own or with other feedback.

• fully own-able erc721 items (or erc1155) - not limited term of ownership
• optionally expirable
• buy initially by burning
• small tax is burned on transfers
• badges minted (with quantity and initial price) by dao vote
• have one ridiculously priced badge that there is only 1 of, like platinum whale or the vitalik unicorn badge or whatever that costs like 1m
• some badges should be assignable by dao vote - special community recognition of an individual or contribution
• may need ability to "wear" or order owned badges to signal preference for presentation in interfaces

Help design (and build!) how badges would work!
