obelisk.ar implements post-quantum dms via nostr-wot already

obelisk.ar DMs are post-quantum encrypted as of this week. keys come from the seed phrase you already have (or should create), messages ride inside ordinary NIP-17 gift wrap, and no relay had to change anything
reading them needs no negotiation: the envelope says what it is. sending needs one cached relay query. for most clients this is an afternoon of work
it is opt-in today because a Nostr identity is a secp256k1 key and nothing else, with no algorithm field. we already version NIP-44 payloads. the idea is in the protocol, it just has not reached the key
formats are public drafts. argue with them before a second client ships against them

flights near the edges (Sydney loop) are longer because planes slow down as they approach the abyss, pilots instinctively ease off the throttle. London-NY-Tokyo stays central, full speed ahead
your flight time data doesn't prove roundness, it proves 𝐩𝐢𝐥𝐨𝐭 𝐚𝐧𝐱𝐢𝐞𝐭𝐲 𝐠𝐫𝐚𝐝𝐢𝐞𝐧𝐭. the closer to the edge, the slower they fly

for sure, that's why i am participating in all the meetings!
it is designed to be fully integrated from day 0, and not to compete, but to enhance it
i am sure a lot of people is building from different directions, and i am opened to listen and learn from all of them
i called it protocol because platforms can architecturally participate of several protocols: bitcoin + lightning network + nostr + gozzip. furthermore, it can also be implemented in other decentralized social network initiatives equally

hey! for some reason i can't get a Signal account with a Vietnamese number. i haven't had time to catch up with that yet
your approach is interesting, to find a way to vouch for relays and a public way to access them based on performance parameters such us latency or availability, geographic area, reliability, spam detection and so on, and query them through a service like purplepag.es would be great. i think that's not my line of work, but probably @nprofile…0j5w could think of something
what i am focusing now is on how to achieve Nostr's original promise: "shift the paradigm of dumb client/smart server to smart client/dumb server", or rather "smart client & smart server"
i have the intuition that we can use our WoT as infrastructure to store and retrieve information, rather than using only relays. Nostr exploration has given us tools and space to understand what works and what not, and i've come to realize that what we thought was fixed and objective, can be dynamic and subjective, just like life itself
relays are amazing as a boostrapping mechanism, discovery, specialized services, curated content, connect to other peers when no other available method, but, users SHOULD define what they want to see or not, and that information shouldn't be public, should be private. what i consume or not by no means should be of common knowledge or arbitrarily served. gatekeeping and surveillance surface can be reduced
i've written a whitepaper that introduces a decentralized trust-weighted storage and retrieval system that can be built alongside Nostr and work in parallel to relays. i'd appreciate your honest feedback: https://github.com/gozzip-protocol/gozzip

hey @nprofile…tz23 . i agree with you, but instead of routing content through random peers, we should use our web of trust. content should be within the people that consumes it the most.
i wrote a paper about it: https://github.com/gozzip-protocol/gozzip

pretty clear breakdown, core argument is strong. relay-based filtering is the right structural incentive. the "tragedy of the commons" point is an angle that i had hard to imagine: if filtering is purely local, you're offloading the mess onto everyone visiting your threads. relay selection as social responsibility makes sense
that said, want to push on something: what happens if we take the relay-filtering model seriously but ask what a "relay" could actually be?
right now clients are dumb readers, relays are smart filters. users pick relays with good policies, system works because operators have infrastructure and incentives to filter well. pyramid, pow.relays.land, paid relays, all proof this works today
but theres a gap. relay operators are a dependency surface, they decide whats stored, for how long, what rules apply. even the best-intentioned operator is a single point of policy. if inbox.yakihonne.com changes its algo or goes offline, every user with it as a read relay is affected
part of why this felt inevitable is that clients used to be genuinely constrained. storage expensive, bandwidth metered, battery a real concern. making clients dumb made sense. but that assumption is aging, phones today have hundreds of gigs, always-on connections, processors that would've been server-grade not long ago. the gap between client and server is narrowing, even if the protocol still treats them as categorically diferent
what if some clients started behaving more like relays? not replacing what you describe, complementing it. a client that forms bilateral storage agreements with wot peers, i store yours you store mine, with roughly matched volumes so neither side is freeloading. both sides have skin in the game which is what makes it stable, if you stop holding up your end i stop holding up mine and we both lose a storage partner
the filtering part comes almost for free. content only propagates within a trust boundary, say 2-hop follows, so spam from throwaway keys never reaches you. not because a relay filtered it but because nobody in your social graph stored or forwarded it. same wot principle pyramid uses, distributed across participants instead of centralized in an operator
the part that makes it not just a nice idea is how you actually find stuff without a relay index. you'd want something like a tiered approach, check local storage first, then try known peers who responded fast before, then fan out a blinded request through your wot if needed, and only hit traditional relays as a last resort. relays become a fallback layer rather than the primary path, which is basically embedding your model as a component
the question is wether both models coexist and reinforce each other. relays handle filtering and inbox routing (works today, should be default), wot-based peer storage adds an availability layer and alternative discovery path that doesnt depend on any single operator. periodic challenge-response checks between partners keep the storage honest without needing anything as heavy as proof of work or staking
curious if you see something structurally incompatible about the two coexisting, or if you thinkk the relay model already covers this ground

i hear you. i think every user should be able to choose what level of security they add to their key stash. today, they have little options, and every user experience is broken on this regard.
if i feel comfortable remembering things, under a scheme like this one which cannot be brute-forced, i may go for this approach. i may even feel comfortable enough as to not create a backup, because i know that if i want to keep the history of my account, i can just create a new one and use the old password (very interesting approach to handling keys hey).
there's another guy that wrote about publishing instead of a passphrase another key that you should back up. so you can have 2 back ups, and one of them is the one you use in your hot nostr client, the other you use it under an emergency to rotate your key.
if the relays start working together on adopting a model or several of these strategies to prevent bad actors, and on top of that little trust, you could have levels of order and completeness that will give you a safety net (OTS or straight an OP_RETURN), then this sounds interesting.

hey David. every existing proposal has the same flaw: if an attacker has your nsec, they can publish the same migration event you can. you can't prove who did it.
i am proposing below a scheme that fixes this using a hash commitment published on day one, a sha256 of a passphrase that lives only in your head (a password or something).
attacker can't rotate without knowing it. if they try, the fraudulent rotation is cryptographically distinguishable from a legitimate one.
key theft becomes detectable, not just disruptive.

just opened NIP-XX: 𝐰𝐢𝐧𝐝𝐨𝐰.𝐧𝐨𝐬𝐭𝐫.𝐰𝐨𝐭 — a standard browser API for Web of Trust queries
tired of every client reimplementing the same WoT logic, fetching follow lists independently, wasting bandwidth doing the same graph calculations. this proposes a shared interface exposed by browser extensions so any nostr web client can query trust distances, scores, and social graph data without reinventing the wheel.
covers:
𝗴𝗲𝘁𝗗𝗶𝘀𝘁𝗮𝗻𝗰𝗲(), 𝗶𝘀𝗜𝗻𝗠𝘆𝗪𝗼𝗧(), 𝗳𝗶𝗹𝘁𝗲𝗿𝗕𝘆𝗪𝗼𝗧() for trust-gating
𝗴𝗲𝘁𝗧𝗿𝘂𝘀𝘁𝗦𝗰𝗼𝗿𝗲(), 𝗴𝗲𝘁𝗗𝗲𝘁𝗮𝗶𝗹𝘀(), 𝗴𝗲𝘁𝗣𝗮𝘁𝗵() for scoring and graph inspection
batch methods for feed filtering
𝗹𝗼𝗰𝗮𝗹 / 𝗿𝗲𝗺𝗼𝘁𝗲 / 𝗵𝘆𝗯𝗿𝗶𝗱 𝗺𝗼𝗱𝗲𝘀
already implemented and live in the nostr-wot extension for Chrome and Firefox → https://nostr-wot.com/download
proposal: https://github.com/nostr-protocol/nips/issues/2236
feedback welcome, especially from client devs who've already built their own WoT logic and know where the pain points are

Built MappingBitcoin because the alternatives are incomplete, centralized, and couldn't keep up with reality.
OpenStreetMap as the source of truth + Nostr for decentralized reviews and verification + Nostr WoT to ensure you trust on your own judgement.

No platform risk. No single point of failure. Just verifiable, community-maintained data about where Bitcoin actually flows.
The infrastructure matters more than the count. Build systems that scale without you.
