Reports
- The State of Bitcoin Mining, H1 2026 — network hashrate, hardware efficiency, mining-pool centralization and economics.
- Sovereign AI in Canada, H1 2026 — which models run on which GPUs, local-inference economics, the Law 25 / Bill 96 / CLOUD Act case, and the open self-hosting stack.
- The State of ASIC Repair & Hardware Longevity, H1 2026 — the obsolescence curve, hashboard failure modes, the open board-repair reference data, and repair-vs-replace economics.
- The State of Home Bitcoin Mining & Heat Reuse, H1 2026 — the miner-as-heater thesis, when home mining actually pays, the 120V/240V/noise reality, and purpose-built hardware.
- The State of Mesh & Off-Grid Sovereignty, H1 2026 — LoRa radio, Meshtastic mesh networking, self-hosted Nostr identity, and the open hardware that runs communications past the grid.
