NIPs
Use hsl for role colors
staab
@hodlbod
The PR proposes using HSL (Hue, Saturation, Lightness) color specification for NIP-43 role colors. Originally named “Use okclh for role colors,” the author switched from OKLCH (a more sophisticated, semi-proprietary color standard) to HSL because it’s more intuitive and predictable when selecting colors.
Key details:
- Original approach: OKLCH color space (which uses a tuple of [hue, saturation, lightness] and fixes many palette-related issues)
- Switched to: HSL color space for better intuitiveness
- Also includes: Updates to NIP-86 role colors in the same commit
NIP-59: relays should reject kind 13 seal events
alexgleason
@Alex Gleason
This is a straightforward proposal that relays should reject kind 13 seal events since these events are only ever supposed to be used inside of giftwraps (NIP-59). By rejecting seal events at the relay level, it prevents orphaned seal events and maintains proper protocol architecture.
Conversation Highlights:
- staab reacted with a thumbs up emoji, indicating approval
- alexgleason referenced a GitLab commit from Ditto Relay that implements this rejection logic: https://gitlab.com/soapbox-pub/ditto-relay/-/commit/ddce82c040e78cc37d3a56b8a7f0448daddf3df2
epoch-based deterministic wrapper keys for NIP-17
fiatjaf
@fiatjaf
This PR presents an alternative approach to NIP-17 (Direct Messages) wrapper key generation. It proposes using epoch-based deterministic wrapper keys rather than static conversation keys. The PR is described as “Another take on #2396,” referring to a related proposal by staab.
Key Concept:
- Uses HKDF (HMAC-based Key Derivation Function) with shared secret and epoch values to derive different wrapper keys for different time periods
- Wrapper keys change based on epochs, providing time-based key rotation
- Clients would paginate backwards through epochs to retrieve historical messages
NIP-XXDLC: DLC oracle announcements and attestations
joemphilips
@hodlbod
This PR resurrects a DLC (Discreet Log Contracts) oracle proposal that was previously closed. It introduces specifications for DLC oracle announcements and attestations on Nostr.
Key Details:
- Recreates proposal from: PR #1681 (NIP-88), which was closed
- Placeholder naming: Uses NIP-XXDLC, kind:xxdlc-announcement, kind:xxdlc-attestation, and kind:100xxdlc-announcement instead of concrete numbers
- Reason for placeholders: Final NIP and event kind number assignments are still pending
- Scope: Limited to DLC v0; corrected the oracle_announcement link and removed Nostr-key fallback from previous iteration
- Origin: The original PR author (conduition) agreed for joemphilips to take over and resubmit the proposal.

Long-Form Content Eco
In the past two weeks, approximately 272,976 kind 30023 events have been tracked (long-form articles), with over 55% being Bitcoin related articles and 45% related to Nostr and other topics across the Nostr Ecosystem.
The digital feed is buzzing right now with a fascinating mix of hard-hitting tech debates, grassroots community building, and a little bit of football. People are actively trying to figure out how to build a free, secure digital world while dealing with the realities of the physical one. Here is a quick look at the main topics dominating the conversation.
Overcoming Barriers and Securing the Grid
A massive talking point across the ecosystem is how decentralized technology can survive and thrive despite growing regulatory barriers. The community is actively exploring clever ways to route private, encrypted communications over existing public infrastructure.
Security is another top priority right now. Everyone is sharing guides and best practices on how to securely set up and store Bitcoin wallets. The overarching goal is clear: keep digital money safe, private, and out of the reach of anyone who might want to censor it.
Social Media and Global Adoption
There is a huge wave of excitement about Nostr’s potential to completely reshape the global social media landscape. Users are comparing the daily frustrations of centralized platforms with the freedom of open protocols, and the consensus is that the shift is already happening.
At the same time, the push to bring Bitcoin to the masses is stronger than ever. The timeline is packed with updates on local adoption efforts and detailed breakdowns of vibrant Bitcoin meetups happening across the UK and beyond. The focus is no longer just on holding the coin, but on actually using Bitcoin as the definitive currency of the future.
Tech Wars and Football Goals
The classic tug-of-war between centralized and decentralized systems remains a daily staple on the feed. People are eagerly tracking every tech update that pushes us closer to a trustless, open-source world, while roasting the security flaws and downtimes of traditional networks.
And right in the middle of these intense debates about monetary policy and cryptographic freedom, you will find a healthy dose of World Cup highlights.
Because let us be honest, what is the point of fighting for financial freedom and censorship-resistant communication if we cannot take a break to argue about the referee’s offside call?
Thank you,
and others, for your work. Enriching Nostr’s long-form content ecosystem is crucial.
