Research & insight on the
physical layer of the digital economy.
How AI compute, stablecoins, regulation, and consensus design converge on a single constraint — power-secured, U.S.-located infrastructure — and what it means for capital.
One rail, no seams: BTX and the post-quantum money stack
Every payment today is stitched from a chain, a wallet, a processor, and a compliance bolt-on — and the seams are where the $3B went in 2025. The case for one integrated, post-quantum money rail built on BTX: post-quantum from genesis, a measured ~22 MH/s MatMul security wall, clean live upgrades, and compliance machine-coded into the rail rather than bolted on.
Seconds to answer: a digital twin of a BTX mining operation
A field report on building a ~500-line, zero-dependency Python digital twin of a live BTX mining stack — mirroring chain state from debug.log with the node down, Monte Carlo forward economics, and turning a gut-feel GPU rental into a $33/BTX breakeven number with a 13% zero-block risk the spreadsheet average hides.
Built to Last: how the BTX team forged a 22 MH/s security wall in 100 days
Launching a proof-of-work chain is easy; securing one is not. In roughly 100 days BTX grew from a single-miner genesis to a ~22 MH/s GPU-defended chain — ~5,000,000× hashrate growth and a ~790,000,000× rise in difficulty, with a clean live upgrade at block 125,000. Every figure measured directly from the BTX mainnet chain.
Every block, on schedule: how BTX retargets difficulty with ASERT
BTX does not use Bitcoin's 2,016-block epoch retarget or Dash's DarkGravityWave for MatMul mining. It retargets every single block with ASERT (aserti3-2d) — 90-second spacing, a one-hour half-life, anchored at block 50,000 — gating the MatMul digest. How the mechanism works and the engineering that makes an exponential safe for consensus.
Digital assets are moving into regulated market infrastructure
Custody, derivatives, stablecoins, capital rules, and jurisdiction are pulling digital assets from a speculative frontier toward regulated financial infrastructure. A neutral, sourced look at the market plumbing — bitcoin futures, spot ETPs, the GENIUS Act, the pending CLARITY Act, and the Basel cryptoasset standard.
20× on Apple Silicon: tuning the BTX MatMul GPU miner
A field report on GPU-optimizing the BTX MatMul miner on an Apple M5 — 6,303 vs 303 nonces/sec, the counterintuitive reason batch size 1 won, and the per-host calibration layer that beats fixed heuristics without touching consensus math.
BTX 0.32.3: the v2 MatMul path goes production-fast
Two days after the block-125,000 activation, BTX 0.32.3 ships the production-grade batched CUDA and Metal implementations of the v2 nonce-bound MatMul path. CUDA jumps from ~14.1k to ~2.45M nonces/sec — roughly 170×. No new activation height.
Block 125,000: BTX closes the MatMul precompute loophole
Two thousand blocks after the last activation, BTX switches to v2 MatMul seed derivation — every nonce now gets its own seed and its own matrices. The precompute shortcut goes away; network hashrate becomes an honest measure of real matmul cycles.
Block 123,000: BTX activates hardening upgrades
Three months after genesis, BTX activated the C-002 shielded proof upgrade at block 123,000 — tightening shielded value conservation, enforcing FIPS-205 post-quantum behaviour, and shipping operator-side mining visibility. What changed and what comes next.
Bitcoin built the chassis. BTX changed the engine.
Mining operators built the megawatt-scale chassis the AI economy now runs on. BTX keeps the chassis and changes the engine — matrix-multiply proof-of-work, dual-use GPU silicon, and post-quantum cryptography from genesis.
When the chain attests for itself: the bank auditor’s changing role
When bank policies and transactions are anchored to BTX, the auditor’s mechanical evidence work falls away — and judgment about whether the right policies were in force, exceptions were used appropriately, and the product is safe becomes the dominant share of the engagement.
Reading the chain, not the binder: supervising machine-coded policies on BTX
When a bank’s rules become machine-coded policies anchored to BTX, supervision moves from periodic paper audits to continuous cryptographic verification. The supervisor’s view of bank policies on BTX.
Machine-coded banking policies and pre-committed exit routes on BTX
Bank policies written in code — versioned, signed, and committed alongside the transactions they govern. How BTX anchors machine-coded policies and pre-committed exit routes for a bank stablecoin.
Mining pools, AI agents, and the Mac mini that earns
Mining pools turn small-scale BTX miners — even a Mac mini on the Metal toolchain — into a steady revenue stream, and AI agents make it hands-free. Native pool support shipping soon.
The agent that pays its own way: AI agents mining BTX
The same GPU that runs an AI agent can mine BTX in its idle cycles — and the agent itself can install, run, and manage the miner, holding its earnings in post-quantum keys. On MatMul proof-of-work, shared GPUs, and compute that funds its own autonomy.
Tokenizing assets on BTX: settlement that outlives the asset
A tokenized bond or building can live for decades — but the chains assets are minted on today use cryptography that won't. Why the durability of the settlement layer, not the token standard, is the unpriced risk in real-world-asset tokenization.
The switch with no operator: a Layer 2 interbank switch on BTX
The interbank switch is the last trusted intermediary in payments. A Layer 2 on BTX rebuilds it as batch settlement with instant cryptographic finality, netting without a clearing house, and a guaranteed exit — no operator to trust.
BTX: when the block reward is a matrix multiply
A live post-quantum settlement chain whose proof-of-work is real linear algebra — the same class of GPU compute the AI economy already competes for. The first system that turns the six settlement tests into running code.
When software spends: settlement for the agentic economy
Autonomous agents already act at machine speed, but the settlement layer beneath them still assumes human administrators. Six design tests for the money infrastructure the agent economy actually needs.
Proof of Useful Work and the 2-for-1 GPU
A cryptographic breakthrough turns matrix multiplication itself into blockchain consensus — at near-zero overhead. The same GPU cycle trains a model and mints a block reward, turning AI's biggest cost into a 2-for-1 asset.
How crypto is quietly saving America
A law you didn't hear about turned 500 million strangers into buyers of U.S. government debt. How GENIUS, CLARITY, and the broader crypto policy pivot quietly replaced China and Japan as marginal Treasury buyers.
