Tips for Relays.

Forget about having a thousand and one relays.

The first option is to pay for nostr.wine, it allows you to use the filter.nostr.wine filter. The filter works both requesting events from other relays and sending events to other relays. In case you want to send events to other relays you have to add the relay with the following syntax:

wss://filter.nostr.wine/REPLACE_WITH_YOUR_NPUB?broadcast=true

Reading list:

wss://relay.damus.io
wss://nos.lol
wss://relay.current.fyi
wss://brb.io
wss://nostr.oxtr.dev
wss://relay.nostr.bg
wss://no.str.cr
wss://nostr.mom
wss://nostr.zebedee.cloud
wss://relay.plebstr.com
wss://offchain.pub

Writing list:

wss://relay.damus.io
wss://nos.lol
wss://relay.snort.social
wss://nostr.oxtr.dev
wss://relay.nostr.bg
wss://nostr.fmt.wiz.biz
wss://nostr.mom
wss://nostr.zebedee.cloud
wss://no.str.cr
wss://relay.plebstr.com
wss://offchain.pub

The next special relay is relay.nostr.band. This relay reads events from all relays and applies a spam filter, in the case of writing you only write to relay.nostr.band but it is a good complement to add content to relay filter.nostr.wine as it only requests events from your contacts and your contacts' contacts. It is not clear to me from which relay is requesting the events as the code is not available.

And finally the relay nostr.mutinywallet.com. This relay uses blastr which is a nostr cloudfare worker proxy that publishes to all known relays. Basically what it does is to read the list of online relays from nostr.watch and all events are queued to be executed in batches by another worker that rotates every 30s if there is an event queued, or once a certain amount of events are queued. In this case the relay is write-only.

In short, your relays could be reduced to 4:

wss://nostr.wine
wss://filter.nostr.wine/REPLACE_WITH_YOUR_NPUB?broadcast=true
wss://relay.nostr.band
wss://nostr.mutinywallet.com

With them you save bandwidth and battery, actually filter.nostr.wine in write mode and nostr.mutinywallet are redundant, but I put the two because nostr.mutinywallet.com has more amplitude because it publishes in all the online relays of nostr.watch and also because it has high availability in case of failure of any of the two relays mentioned above.

The same case is applicable in the case of reading for filter.nostr.wine and relay.nostr.band.
