Every claim below is dated, labeled, and cross-client tested

Same protocol.
Most clients render less of it.

NOSTRAS doesn't invent its own network — everything here is a real, spec-following Nostr event. What's different is how much of the spec actually renders, and two payment mechanisms nobody else has built. We tested the difference ourselves, against a real popular client, and wrote down exactly what we found.

Cross-client verified

Real event kinds. Confirmed invisible everywhere else, right now.

Nothing below is a proprietary format — a poll is kind 1068, a thread is kind 11, exactly as their NIPs define them. We published each one for real, then opened it in Yakihonne — a genuinely popular, independent Nostr client, not a strawman — three different ways. All four came back empty.

NIP-75 confirmed

Zap Goals

A fundraising target with live progress summed from real zap receipts, updating as sats actually land.

Tested in Yakihonne, Aug 14 2026 — did not render at all.

NIP-7D confirmed

Forum Threads

A titled discussion post with flat, forum-shaped replies — closer to a real conversation than a single tweet-shaped note.

Tested in Yakihonne, Aug 16 2026 — permalink, profile feed, every tab: not found.

NIP-88 confirmed

Polls

Single or multiple-choice, with live tallies from real votes — each voter's most recent choice counted, per spec.

Tested in Yakihonne, Aug 16 2026 — permalink, profile feed, every tab: not found.

NIP-F4 confirmed

Podcasts

A real show, real episodes, a native audio player — publish and listen without leaving Nostr.

Not a NIP — our own protocol, built on real ones

Paid articles and podcast episodes: a payment rail no other client can open.

The title, summary, and cover image are ordinary public NIP-23 fields — any client renders those fine. The body is NIP-44-encrypted. Unlocking it means paying a NIP-90 job that holds the decryption key and returns the plaintext only once a real Lightning payment settles — straight to the creator, plus a small flat fee to NOSTRAS for running the unlock service.

This can't become portable just because another client "adds support" — there's no spec to add support for. The unlock mechanism is a convention we invented: specific tags, a specific DVM job kind, a specific two-step payment flow. A competitor could only interoperate by reverse-engineering our exact protocol, not by implementing a standard.

Tested directly: a real published paid article, opened in Yakihonne — rendered as raw, unreadable ciphertext with no unlock button at all. Confirmed Aug 14 2026.

NIP-90, self-announced

Real AI tools, one click — and an open service underneath.

Each of these is a standard NIP-90 job. The DVM that runs them announces itself over NIP-89, priced from real token cost, paid per job over Lightning. Any NIP-90-aware client or tool could call the same service directly — what's actually exclusive to NOSTRAS is that it's already wired into the feed with one click, not the service itself.

Summarize

Long note, one tap, the gist — priced by the actual job, not a subscription.

5002 → 6002

Translate

Pick a language, get a real translation back through the feed.

5050 → 6050

Ask Claude

A always-visible box to ask anything — no account, pay only if the job completes.

5501 → 6501

Spam / scam check

Publishes a real NIP-32 label, so the verdict is independently queryable by any client — not locked inside ours.

Pay a NIP-99 listing's seller directly over Lightning, get back a public, independently-verifiable receipt — not locked inside our own UI.

Beyond NIP compliance

Not a feature. An architecture.

A few things here aren't about which events render — they're about what running your own relay actually buys you, independent of any single client's feature list.

01

Notifications tied to a relay you actually control

Push notifications are gated by a real NIP-98 signature check against NOSTRAS's own relay — not a third-party notification service sitting between you and your mentions, DMs, and zaps.

02

The relay participates in the network, not just this app

Real NIP-66 self-discovery and NIP-43 membership — the relay describes and manages itself to the wider Nostr ecosystem, whether or not you're using NOSTRAS's client to look at it.

03

Own your relay, not just your keys

The client and the relay are paired by design. Your keys already leave with you if you ever switch clients — this is about your data and your node's behavior doing the same.

Methodology

How "confirmed" actually gets earned on this page.

Confirmed means we published the real event ourselves, then opened it in an actual alternative client — checked the direct link, the publishing profile's own feed, and every other tab that client offers — and wrote down what we saw, with a date. If a claim here isn't marked confirmed with a date, we haven't tested it yet, and we say so rather than assume it. A claim that later turns out false costs more trust than one we just hadn't made yet.
