KeyKiller is the world's highest-performing CPU-based Satoshi password cracker. It leverages modern CPU instruction sets like AVX2 and AVX512 to achieve unparalleled computing performance. Deeply optimized for the operating system, it strikes a balance between speed and accuracy, making it the ultimate tool for password cracking.

After optimization, version 3080 is equivalent to version 4090. I fixed address matching errors and private key conversion errors, modified the random generator, added puzzles suitable for specific regions, and more. It is commonly used in puzzle games, Brainflayer, Keyhunt, BitCrack, VanitySearch, etc.

JetstreamDB is a universal filesystem, cache, memory, database. It is a component to build into solutions for management consulting customers. It has been running in production since April 2023. The logo was inspired by the tea clipper. It intends to be a great data store without AI like tea clippers took the seas before ironclads.

It is an open-source component, but we offer paid services with audit, system security reviews, benchmarking, and warranty. Jetstreamdb is available up to 6 TB low latency RAM with optional extra 50 TB SSD configurations for about $150/hr. https://calendly.com/hq-schmied/30min

Leonardus is an open source project. It is a minimalist, stack-based programming system designed as a flexible framework for implementing and exploring algorithms. The syntax and semantics of its scripting language, LeoScript, are inspired by PostScript and Forth. It is extended with a prototype-based, object-oriented paradigm, has seamless integration into JupyterLab and Docker, and provides a concise and expressive environment for learning and experimentation.

The project name is a nod to Leonardus Pisanus, who was named and became known as Fibonacci.

Consult the project's GitLab Pages for documentation.
