Section 2. Purpose and Access:
The NextBlock relay exists to store and broadcast campaign content, bids, matches, and payouts for NextBlock’s Billboard app. It is publicly accessible for reading and only accessible for writing by NextBlock buyers and sellers at wss://relay.nextblock.app.
Section 3. Supported Events
The relay accepts the following Nostr event kinds:
- Kind 1: Short text notes (campaign captions, hashtags).
- Kind 5: Deletion requests (if feasible).
- ContextVM
- PROMO Protocol
Section 4. Storage and Retention
Events are stored on the NextBlock relay for 90 days, after which they may be pruned based on storage availability. Campaign images are hosted by Nostr Build (see https://nostr.build/tos/), not the relay. Once posted, events persist until pruned, NextBlock cannot delete them due to Nostr’s design.
Section 5. Visibility
All accepted events are publicly visible to anyone connected to the relay or syncing via other Nostr relays Authentication is required to write.
Section 6. Moderation
The relay does not censor content unless required by Texas or U.S. law (e.g., illegal material). It may reject events for technical reasons (e.g., invalid signatures) but not for their message.
