The arkade sdks should have almost everything you need minus the web server for lnurl which is dead simple to build up. You don't set up your own arkd, you just implement a lightweight wallet and done! No api key needed.
Or you can use Arkade btcpay plugin and have btcpay give you ln address out of the box :)

No, this doesn't refer to the typical tps measurement used by blockchains.
I refer to the pragmatic upper bound for creation of new vtxos within a single onchain tx.
This bound is mostly defined by interactivity rounds between participants to construct the covenant. Since we do not have introspection covenants, we use a a series of n-of-n musig transactions. More vtxos = more interactivity.
We've had a functional ark for bitcoin for almost a year now, and since then we've optimized heavily along with plans to go even further. We have methods to achieve the above in concurrency, so that even with a single onchain transaction, we can create higher vtxo counts, without increasing interactivity for each VTXO owner.
In terms of "tps", I would say it is similar to lightning in that we have offchain instant transactions, but with actual transaction composability -- just craft a bitcoin transaction, sign, and submit.
There is of course no free lunch: one must swap their existing vtxos for new ones that are created with the commitment transaction (covenant session) described above, a trustless swap through connector outputs, for two reasons:
Batch expiries: these covenants have an expiry that allow the ark operator to reclaim its initial liquidity.
Switching from preconfirmation security (previous owner + ark operator collusion risk) to bitcoin finality (fully under your control). This also prunes the unilateral exit to a minimum tx set for broadcasting to.covnert vtxos to utxos.

This whole spectacle that Ark is "gimped" without a covenant is way over the top.
Yes, Ark can be better with covenants. In fact, at @npub1hf5…dp8n we have both variants developed and concluded that a covenantless variant today is not only viable, but can exceed expectations through the right optimizations and engineering. We have a path for multiple hundreds of vtxo creation in a single commitment transaction while keeping the interactivity at an acceptable level.
We also have paths of varying methods to mitigate the approaching expiry dilemma.
Ark does not need covenants. It is FUD to state otherwise. You'll see soon enough though!

Unsure what you mean by "remixing".
If you're referring to the need to batch swap vtxos because of the expiration, then yes. Especially because you said you have a server?

Dust amount - minimum amount a bitcoin transaction output is allowed through current policy. Since ark has unilateral exit, we currently enforce it. Although you can always go to a miner out of band and get it included in a block but thats more of a cheat code than pragmatic.
However we know that at that amount, perhaps it's not enforceability that matters, but rather the claim, and collecting a sum of claims higher than dust should allow you to go to enforceability again. Work in progress and just the rationale right now, but it's in our considerations

It's my fault for the lack of awareness. I don't promote my work much because I feel my time is best spent researching and building the tech. I rely on people to discover, understand and help promote it, which hasn't been very effective so maybe this is where I should change. I’m better with code than with words though, as the quote goes. 😁
This plugin is something I took on myself to develop but it was only the first step in the grand scheme of things. Zksnacks supported me immensely and we were going to take over the world, where every spend was actually a coinjoin, until the samourai situation unfolded.
There's still hope, but it will have to execute differently now. The tech is sound and is agnostic of use, whether it is privacy, scaling, or both.
Just need to get the message across to get the right resources and connections.

Everyone was too busy focusing on postmix tools to realize you don't need a postmix tool if everything can happen in a mix!
PSA: @nprofile…kvl9 with the coinjoin plugin has been able to handle payment batching in coinjoin directly since day one of its release.
And a (not so) secret project that I have been working on for years will soon transform coinjoins into one of the best payment protocols out there with massive cost savings and privacy gains for everyone involved

I'm not saying it isnt, it obviously is. But it's not going to be the next firebase/parsley database with the same performance profile that you can get for free with the extra open protocol magic. You should definitely build your own proprietary, optimized backend but the point is that the "less optimal" nostr req is still there to not gatekeep data flows

The " other stuff" in nostr are just different constructs of notes. If you're using nostr as simply a database for your app then you're just not aiming for real usage. But being able to interop through a common format in a well defined communication layer is the golden goose.

- reply

You are overestimating the effectiveness of a vpn here. The reality here is that we are focusing on very sophisticated difficult to execute attack vectors. The vpn is your only shield for all identities pushing to the relay here. Sure, https/wss encrypts the content, but an attacker that has compromised a vpn operator will listen to events on nostr relays that the vpn has connections to by its users, and can artificially delay data transfer to do timing analysis on events to correlate which ip sent which events with which pubkeys.

2024-10-09 20:34:02 UTC

- reply

Correct me if I am wrong, but wouldn't using something like rise up vpn, a third party operated service, give each third party all the data needed to correlate everything?
A vpn operator knows every source ip and their every destination and action and the promise of no logging is just that, a promise.
This is literally why people use Tor, and generate separate tor circuits per required identity.
PS, regarding wabisabi, circuits are constructed in advanced to prevent delays around tor circuit execution (although I think this is overkill), but also input, output registrations and anonymous credential reissuances has randomized delays built into it by design to prevent such correlation.

Zksnacks was built through years of sweat and blood by @nopara73 with no funding. Everything had to be researched and built from scratch, with not even a fraction of available research, resources and tooling. The amount of work that has been put into it and over such a long span of time is incomprehensible unless you've seen it unfold in front of you leading to the giant zksnacks ended up being.
Mutiny's journey is still young but what they've built on a relatively small startup budget is insane.
Your coinjoin protocol is barely a protocol and is so basic and missing key aspects that nobody that's been in this long enough will take seriously. And if you want their level of resources commit to it and raise money like mutiny did.
Every post about coinjoin, you spam/hijack shilling your stuff. It's rude, and really annoying.
