The Map No One Read

Twelve years before the whitepaper, three NSA staffers wrote a report mapping every state-of-the-art anonymous electronic-cash system of 1996 — and exactly where each one stopped. On how ideas move through time.

Hedging the Block: A Hashrate Derivatives Primer

What a hashrate derivative is, why miners need one, why earlier attempts stalled, and how the broader ‘blockspace as an asset class’ thesis fits together. Drawn primarily from Alkimiya’s published research.

On the strange peace of clearing a years-long backlog with AI, learning to rest, Solomon’s seasons, and a six-year-old’s verdict on the ocean.

Mirrors of Society: Audiovisual Narrative as Anti-Destiny

An essay on the cultural functions of television and cinema across seven cinematic traditions — Hollywood, Europe, Brazil, Italy, Argentina, India, Japan/Korea — and on art as expression, resistance, and social mirror.

When the exercise of one right becomes the limit of another — reflections on morality, empathy and the mechanisms we invented to supply what ethics alone could not guarantee.

Homoiconic Continual Learning: bridging Lisp's self-referential core with neural plasticity

An assessment of the Homoiconic Continual Learning (HCL) framework: where the analogy between Lisp’s metacircular evaluator and neural continual learning holds tightly (LoRA frozen cores, in-context mesa-optimizers), where it breaks (reversibility), and what would turn it from metaphor into theory.

From LISP self-reference to self-modifying neural architectures: a literature survey

The intellectual arc from McCarthy’s 1960 eval/apply to modern self-referential transformers is not a metaphor — it is a precise technical lineage. A bibliographic map across nine research areas, from homoiconicity and fixed-point theory to mesa-optimizers and recursive self-improvement.
