A high-throughput multicast Bitcoin transaction distribution system, with a roadmap towards billions of transactions per second.

Features:

- Control channel for block header announcements, operational mechanisms, and network topology automation

- Separate channels for subtree, subtree grouping, and transaction load

- Transaction load sharding by deterministic multicast group membership based on TXID

- Transaction specialization filtering and retransmission both unicast and multicast, to connect edge networks only interested in a portion of the transaction load for whatever reason

- NACK-based retransmission of missed packets via hash chain gap sequence tracking (per sender, per shard) with automated caching endpoint beacon discovery and tiered network distribution

- BGP-AnyCast based transaction ingress

Basically all the topology pieces to scale the actual small-world network for Bitcoin miners or transaction processors; dense at the core, with layered and sharded group distribution towards users at the edges. Right now just site or org-scope multicast in planned, but provisions are being made to extend via MP-BGP eventually.

For BSV Blockchain but could work for the other Bitcoin variants too, if they ever wanted to scale.

An extension module for Redis or Valkey for in-process Python execution, based on Monty. Learning playground for my Rust skills mostly, but gradually over-engineering it into a whole new ecosystem of sort :-) https://github.com/xelato/taranaki

An image logic puzzle game about nonograms[1] called Nonoverse[2].

I’m automating App Store media creation; both screenshots and app preview videos can now be recorded automatically; this way they should stay up to date and show correct content for a given locale.

I’m also adding translations; if anyone would like to help (with translating or testing new locales) let me know!

Early results are already live in the App Store page.

I’ve been working on Broadcast since Sept 2024:

https://sendbroadcast.net

It’s a self-hosted email marketing/newsletter app. The basic idea is: own your subscriber database, run the app on your own server, and send through SES/Postmark/Mailgun/SMTP instead of being locked into another SaaS.

Not trying to be “Mailchimp but cheaper”. It’s more for technical founders, agencies, and consultants who want a boring, controllable email tool they can deploy for themselves or clients.

I’ve kept the changelog public because I wanted the work to be visible: https://sendbroadcast.net/changelog

My buyers are typically people who want to own their data and are in regions that have strict data privacy regulation/laws.

Interesting fact: This was my real last project where v1 was built by hand before AI coding became the norm in the software industry.

I finally cleared a roadblock that was preventing me from writing more posts and sharing some of the photos that I take -- I patched Hajime -- https://sr.ht/~hxii/hajime/ with the functionality I was missing from it.

So now I can get back to the project that I was actually working on (but mostly deferring) for some time now -- boku -- https://sr.ht/~hxii/boku/ which allows someone to write a sequential series of tasks to perform without using code

Fast, customizable, and extensible dock application -- fully written in Python, with built-in applets and full Linux desktop integration.

Working on a bread recipe community where you can share and iterate on bread recipes. It's out of personal interest to be able to record my bread recipes and thought it might be interesting for others too.

However, I worked on it for the past ~5 years on and off (well, mostly off) and rewrote it too many times. Now finally close to releasing, bought a domain and setting up all the last remaining things.

1) “AI harness plugin build system” to help improve reliability of and increase compatibility across the fragmented AI coding harness plugin ecosystem.

2) Claude code plugin based on some ideas found in https://www.anthropic.com/research/emotion-concepts-function The main idea is to add hooks that inject “baselines” under some conditions to counteract certain “emotions” that can cause subtle misaligned behavior in agents

3) Final Fantasy XI custom client remaster in Bevy/Rust alongside an MCP integration that aims to allow agents to play autonomously on private servers à la “Claude plays Pokemon”
