I want to **run a relay** financed by a tiny percentage of its users and strongly believe

in the following being a way to align incentives for all clients and relay operators:

For this bounty, the minimum requirement for the resulting relay is:

* relay is as efficient or better than [strfry](https://github.com/hoytech/strfry) at supported nips, synchronization between instances and handling concurrent connections

* nip42 support

* all read and write operations are metered per connected pubkey: milliseconds spent on queries, query count, events sent, event kBs sent, etc. (If Alice pushes Bob's events, it gets tallied to her pubkey - the one authenticated via nip42)

* allow managing group of primary (TIER 0 or T0) users via API

* secondary users are those followed by T0 users etc.

* define limits depending on follows distance to primary users, using five tiers: 0 = primary users, 1 = follows, 2 = follows of follows, 3 = follows of follows of follows, inf = all the other pubkeys

* allow configuring hourly, daily and monthly limits per tier and metered aspect.

**This bounty was created with the goal of actually running a relay with this feature and will not be awarded for a proof of concept that is not a fully functional and performant relay. Strfry is "good enough". If you want to implement the proposed feature in a different relay, please reach out to discuss first.**
