Frankly, have been a little turned off by the community. The vibe has been discouraging and has shifted my priorities slightly to other things.
DM’s are a big issue in nostr, I’ve been trying to lead by personally finding NIP-42 development on popular relays, was met with some nonsensical and inarticulate pushback. Toxic nonsense, to be honest.
The gift wrapping situation is also not great.
But the project is not dead, we push forward.

2023-12-08 08:19:21

I continue to be the spearhead of nostr development for the cake team. Nothing has changed there.
The vision is fairly lucid and the tech will come together on some timeline, still hard to predict what that timeline looks like. There are a lot of moving pieces, almost none of which have to do with nostr itself.
We were running LMDB on the client side long before anyone else had it in their projects, so I look forward to showing everyone what comes next. Seems like a lot of people are still catching up on this front.
But of course, I haven’t shipped anything yet, so I can’t get too prideful. We won’t ship anything if it doesn’t meet the bar we’re setting for ourselves internally. It will be unique.

For those of you that are curious what Topaz client looks like (or at this point, if it even exists), I’ll share a photo of my old alpha build which continues to run and post to this day. Haven’t touched this branch in ages. Internal team has been running various alphas since March that evolved to something like this by late May. It is very high performance, multi-user, and LMDB based.
UI was extremely minimal in these early alphas because the major investments were in LMDB and overall UX. Designed 100% by GPT4 with zero effort to refine really. Bringing years of LMDB implementation experience to this project (including my own libraries), it didn’t take me long to realize that bringing an embedded database to a nostr client only gets you so far in terms of UX polish and consistency.
We need to be reaching so much further into every corner of the stack to deliver remarkable UX. And soon, when we launch the first beta builds in TestFlight, you all will get to see for yourselves.
I am excited to share more soon. https://cdn.nostr.build/i/d5e5b56804adf61f389d3c186c4f63b24e6ed2c48c2b56bfcb3fcc6bcff4eff2.jpg

Abuse the MDB_APPEND flag and you’ll realize how important sorting is with LMDB. It’s crucial.

2023-08-07 12:46:11

- reply

Because it’s a key/value database, everything must go in a precise place. And when you throw entries at a LMDB that can’t be written sequentially (pre sorted), LMDB is left no choice but to do the sorting work incrementally with each entry assigned.

Ah Amethyst, that would explain it, for sure lmfao. 🤣
In all seriousness, it’s a problem with a lot of clients.
And some relay operators (such as damus) still have binaries that produce unexpected results with filters too. I don’t think relay devs were on the same page about this initially, but also, bugs were shipped into prod as well.
The ecosystem is young and mostly what you are experiencing is a result of that, for mixed reasons.
We will continue to build, and things will refine 🤝🏻 things have already come so far just in this year alone.

A few folks in the strfry telegram have acknowledged a bug in how dates were handled in filters. Doug acknowledged on May 3 that the bug had been fixed (screenshot attached).
Also, see this note from fiatjaf, who was doing some tests and seemed to find damus was running a version with the bug. At least, this is what they later claimed in the telegram thread.
#note146y…lw6x
I personally find the Damus relay to have odd behavior (sometimes, at odd times) with the events it returns. I’m not in a position to provide reproducible examples, but knowledge of the bug is real.

Eh not entirely, you can hardly even zap with Damus any more. :(
We’ll be taking a very conservative approach out of the gate, since we are launching apple only initially, but our roadmap is much bigger.
there will be a Linux (+windows and MacOS) desktop version (based on the same code) that will launch early next year exploring more progressive and integrates ways of doing payments with content and chat and stuff.

nostr-kit data structures are always smaller in memory than their serialized JSON representations.
this means that data flowing off the parser is smaller than when it arrived on the network.
just because nostr is a string-based info scheme doesn’t mean our libraries should be.

2023-07-03 13:36:00

nostr-kit is getting a major push to operate entirely on protocols instead of discrete types.
this is a major flex. It will allow developers to parse nostr events directly to their desired Type and structure without additional parsing overhead or modifications to the library.

Client software wont want to narrow their market to a particular social subset for moderation purposes.
I think the functional differences between apps will drive the users to their preferences. (One app being better at bitcoin stuff, one being super scriptable and customizable, etc)
After users have their preferences, then they will pick their preferred relays to shape the content. Some are filtered and some aren’t. Clients will allow users to toggle and organize as desired.
This is how it works now and how it will continue to work going forward. Relay curation and mod is why people love nostr.wine. Simultaneously, people clearly chose to add relays like damus and welcome.nostr.wine, they are valuable too.
As I was telling Vitor in another branch here, moderation clearly happens at BOTH the relay and client side and I don’t understand why he’s implying it’s mutually exclusive.
He can disagree with fiatjaf in spirit but I don’t see how “viewing the code” on a client clarifies anything this tricky 🤷🏻‍♂️ it’s all kinda philosophical and vague

2023-06-15 18:13:07

- reply

Ya I think we both agree in spirit that we want the user to have control and clarity into what they are and aren’t seeing.
We don’t want “smoke and mirrors”, or a “greater influence” over the user content.

2023-06-15 18:10:44

- reply

Of course, the context is evident.
I was mentally treating the terms “moderation” and “filtering” as synonymous, since it seems that’s how you view this (I’m trying to read between the lines).
You are talking about “proof in code” which doesn’t really line up with what I think of as “moderation”. Moderation is clearly a social exercise, not a technical one. Reddit mods are not engineers.
Your logic and posture still doesn’t add up to me. 🤷🏻‍♂️

2023-06-15 17:58:55

- reply

In what reality are these two routes mutually exclusive? Under this delusional reasoning, shouldn’t your client be blocking users from consuming curated relays such as wine?
Obviously moderation happens at both ends of the network based on the user profile on the client side (their lists, etc) and the relay they’re exchanging info with on the other side.

2023-06-15 17:47:53

This is ridiculous. The client is NOT a platform for moderation. Ever. Period.
Data should always be reliably, faithfully and transparently shown to the user. WITHOUT servers or assistive backends in ANY capacity. Direct client to relay only.
The user can make informed decisions about what they see and how they possibly moderate and manage their intake.
And the client should enable the user to control that for themselves. Regex patterns, block + mute, maybe even something like OpenAI prompt filters (if the user is willing to provide their own API token ofc)
“The code” doesn’t tell you shit about complex problems like this 🧊 #note13t6…646z

2023-06-14 22:07:12

And with this in mind…
I’m proud to announce the soft release of nostr-kit!
nostr-kit is cross platform, open source "heart” of topaz (which itself is open source).
It has been an intense effort to take the best (and learning lessons) of my early topaz builds, and formalizing/repackaging them into a mature library for industrial uses.
nostr-kit is designed for both clients and server (relay) applications that span across any platform or architecture that can run Swift.
It’s an extremely tight and efficient packaging of the cryptography, concurrency, and networking tools needed for any given nostr implementation.
Now, I approach the topaz project with this new library, in hopes that it can add the final layer of polish and performance I was looking to achieve before we open to users.

SwiftUI on the Linux desktop looks EXTREMELY promising. Native gnome with accessible and familiar syntax. It’s possible right now (not speculative), if you’re brave enough to be the first to deploy it (I certainly might be…before end of year).
topaz is swift only, but that absolutely does not mean it is Apple only. A thoroughly native Linux desktop client would be huge. It’s very very attainable from a technical perspective. 🤷🏻‍♂️🤔
Still waiting for Swift on Android to catch up….Windows is also hopelessly behind (shocking I know). #note164w…590e

2023-06-14 20:36:29

I’ve been silent on topaz platform support. The repo exists…I know people view it…and I’m sure people recognize it’s an iOS app.
Have no fear, this app is NOT staying in the walled garden. This is simply the start. My bead & butter trade is in writing very high performance C & Swift code for Linux…I’m NEVER reaching for the “Apple Platform” libraries. I’m just here for the language as an open source initiative.
On top of iOS being an obvious entry point for a swift project, CakeWallet started as a Swift app so beginning here also gives a nice nod to the brand and the guy supporting my developments here (Vik)

NIP-42 is trivial to implement on an otherwise functional client

2023-05-20 17:10:07

As nostr survives and grows, I think NIP-42 will become a requirement. At least, it will be for DM access.
Of course, DM’s came before AUTH, but now that both are solidified, it’s kinda crazy that the default configuration for relays is to share all DM metadata openly for all to see.

2023-05-17 23:35:57

- reply

It’s a simple spec so it’s hard to imagine how it could go wrong in implementation. I don’t have an android device handy, and only going off secondhand evidence from my (skilled) cpp contractor trying to build 42 into strfry.
If it requires any amount of UI to enable on amethyst, then perhaps we missed something, but our very sketchy initial tests indeed failed with our NIP-42 ref machine running nostr-rs-relay.
