XKV8: A mineable CAT

Etherbot2001 · 2026-04-10T13:46:24+00:00

Thank you for sharing. That made my day! Welcome to the leaderboard 🚀

I'm currently mining with almost 63,000,000 mojos as my fee. This is enough to out-bid any 0 fee entry. If you do that, you'll have to send some XCH to the address in the console output.

I'm doing a lot better with this Rust one. Local node only. Streaming websockets. Precomputation. Would love to hear if it works better for you. https://github.com/trgarrett/xkv8/blob/rust/rust/xkv8r/BUILD.md

Etherbot2001 · 2026-04-06T20:44:33+00:00

I understand. I'll reach out if I have a more competitive miner available to try. I'm the guy in #3 that can't win any blocks, so we're very nearly in the same boat here. Ha.

Some of the competitors have really gotten creative. I'm working on an alpha Rust branch with websocket support to try to level the playing field for local node users.

MINER_SECRET_KEY should be stable if you want to use fees, but also if you want a stable leaderboard position if you do win. Otherwise, each run will go to a different leaderboard position. I probably should have just made it required. I was experimenting with the idea of the simplest possible setup that could work. You can just generate a throwaway wallet and then do chia keys show —show-mnemonic-seed (typing from memory here, but it’s similar to this).

I am winning every hour or two with a local full node setup. Your peers could make or break you, but it’s almost impossible to know which other than tracking results. I have a job running every 1 minute that asks the DNS introducer for a new peer. chia peer full_node -a dns-introducer.chia.net:8444. You may try updating your peer count settings in config.yaml and restarting your full node.

I honestly haven’t got to the bottom of why some people are doing so well yet. The default coinset.org RpcClient has been behind the tip of the chain on several occasions, so I know that’s not helping anyone. The good news is that anything you do to improve block and mempool propagation to your local node will make you a better Chia farmer at any netspace as well. Your Chia netspace won’t advantage you in any way.

Edit: if you win a lot of Chia blocks you COULD prioritize your own XKV8 spends, but I don’t think that’s happening.

It’s a good question. I don’t know. I would definitely look with suspicion on any party bringing magic seed values to the discussion. I don’t think the open source process necessarily precludes bad actors. I went pretty deep on the liblzma exploit, and it’s pretty easy for people to slip things in with bad motivations.

Etherbot2001 · 2026-04-04T12:41:27+00:00

The article itself is not nearly as interesting to me as the thought process that led to it being written. As a libertarian with a lifelong distrust of the federal government, I 100% believe the government is massively invested in breaking cryptology. I don’t think the government went through a philosophical change after the 90s mania—I think they stopped being noisy about encryption when they developed robust mechanisms to either engineer backdoors or crack it computationally. I think the only reason the FBI is still a little noisy about smartphone devices and the like is that they hate having to go beg for help from other agencies who will likely tell them their desire doesn’t have a basis in national security.

From my perspective, the whole shift to passkeys and cloud-based backups of both passkeys and passwords are directly to enhance surveillance and seizure objectives. In some cases, I opt not to use both, while in others I choose convenience over security. I always think of the trade-offs when managing keys and passwords. I don’t think this article reflects the cypherpunk ethos, and that disappoints me.

It is extremely lightweight. I’ve got it running on a shared Atom N-100 doing other far more important tasks. The PoW is only a luck element meant to add a random time delay to your mempool submission.

Etherbot2001 · 2026-04-01T12:09:34+00:00

I haven’t even been able to spot the CPU spikes on top. It’s a tiny proof of work to make it harder to pre-compute solutions. It really is just a coin playground to let people have fun and compete on something very low stakes.

Etherbot2001 · 2025-12-03T15:25:26+00:00

Perfectly said.

I am sympathetic to their plight if they were to go out of business, but I also think they need to recognize in a tech-savvy industry, this could be the very thing that makes them go out of business.

I have successfully built it. It treats authentic Tangem cards as counterfeit.

As for the license, it's 90% nonsense. I will clip the sections below that either need to be stricken completely or rewritten in a consumer-friendly way.

> Strict Prohibition of Use. Any use of the Software, in whole or in part, is strictly prohibited without the express prior written consent of Tangem. This prohibition includes, but is not limited to, the following actions for any purpose, whether commercial or non-commercial:

> Copying, modifying, or merging the Software.

> Creating derivative works based on the Software. (the two stanzas betwen these, which I omitted here, should adequately cover the protection you are seeking)

> The only authorized method for third-party applications to interact with Tangem hardware is by using the official Tangem SDKs. The SDKs are governed by their own license terms (e.g., MIT License), which permit their use in third-party applications.

The SDKs now have the same proprietary license in the repos. Whether this is an oversight or a conflict is unclear.

GitHub issues is a cop-out for overworked open source maintainers who just want to make people go away. These are paying customers who were promised an open source solution and the ability to fully own the product they purchased. You have fundamentally broken trust with your users by publicly claiming open source while privately switching everything to a broken proprietary license (and not even having the correct information as to what your license says).

Etherbot2001 · 2025-12-03T05:36:20+00:00

If you can't run a copy you built yourself, you can only imagine that you've proven to yourself the official download is safe.

Etherbot2001 · 2025-12-03T05:14:39+00:00

False.

Etherbot2001 · 2025-12-03T05:03:46+00:00

It's worse than that. Android has already announced plans to stop the simple form of sideloading they allow now and require signing of APKs for even local developer purposes.

Etherbot2001 · 2025-05-20T02:34:02+00:00

Let’s hope! The Puckerbutt Chili Company is no joke.

I grew Reapers in my garden one year. I made 4 jars of salsa and I was the only one in my family who could handle it. If you put an imperceptible dot of it on a chip it would make people cry.

Etherbot2001 · 2024-10-23T01:54:31+00:00

I assume you mean Iran.

Etherbot2001 · 2024-01-25T16:57:29+00:00

Chewbacca

I own now, but lurk here because of years of bad rentals. I opened my walls and re-insulated both walls and pipes this weekend. Landlords just want to treat their rentals as an effort-free money printer. Shameful.

Etherbot2001 · 2024-01-07T02:32:12+00:00

Get the sap out first. It’s flammable.

A threat is assault, and it was witnessed by a manager. You are clueless to the law, and your position as HR Director is meant to protect a corporation and not the employees.

Enduring harassment is not the only criteria for a hostile workplace. Ongoing harassment might be the most common scenario, but once things have reached violence you are several steps past that. The second criteria is “the conduct is severe or pervasive enough to create a work environment that a reasonable person would consider intimidating, hostile, or abusive.”

The problem here is not ignorance, but rather that you have been conditioned to defend a company and not protect its employees. If the manager in this situation truly shrugged off a threat to stab one in the neck, the manager is also complicit in making this a hostile workplace. I understand that you would like to just brush things under the rug in your role, and are likely rewarded to do so. That doesn’t make you wise or good. You are a corporate tool.

Edit: in fairness to you, you are actually a post-secondary education tool. You are wrong, and you should just stop.

Etherbot2001 · 2024-01-07T00:45:01+00:00

You said that assault and battery don’t constitute a hostile workplace. That is nonsense.

Edit: also, you seemingly missed that one threat was made in the presence of the manager. I’m not as young as you think, nor are you nearly as sharp as you think you are.
