More work from every watt.
GrnBit builds OCTO SI, agentic orchestration that runs power, heat and compute as one system, to get more work from each watt: mining machines first, AI servers after. Its first live test, on 13 mining machines with four GPUs as a calibration control, is proposed, to be metered and attested by an independent engineer.
How the proposed test is built
- Measured by someone elseAn independent engineer owns and seals the meters.
- Judged against the bestOCTO SI must beat the best setting the independent engineer can find, not only factory settings.
- The bar is set firstA pass gate is registered with the independent engineer before the test runs.
OCTO SI
One system for power, heat and compute
- What it is
- OCTO SI is built to read the machines, the power feed and the cooling together, rather than tuning each machine on its own.
- What it does
- It is built to set them for the most work per unit of energy, inside the site's limits.
- Why it matters
- The aim: more work from each watt, on mining machines first and AI servers after.
OCTO SI is simulation-validated, so far only on a digital twin: its edge over stock firmware is not yet measured on live hardware. It is licensed to miners only after a controlled 90-day measurement on mining machines, attested by an engineer with no interest in either party. That is why the first step is a test, and why someone else measures it.
Proposed. OCTO SI's first live test: 13 mining machines in three arms and four GPUs as a calibration control at a related-party site in Oklahoma, pre-registered, independently metered and attested; the result published, pass or miss. The protocol is frozen and hashed before any hardware is bought; the attestor owns and seals the meters and runs both baselines.
The first live test · Next
- On
- 13 mining machines in three arms (five under OCTO SI, five under the best expert tune, three on stock firmware); four GPUs as a calibration control
- Where
- A related-party site in Oklahoma, part-owned by both founders, to be billed at its grid cost plus connection fees, with no margin
- Against
- Factory settings, and the best setting the independent engineer can find; OCTO SI must beat the best by its pre-registered gate
- Measured
- Energy at the wall per unit of work, as the frozen protocol defines it
- By
- An independent engineer, who is to own and seal the meters
- Pass
- A gate registered with the independent engineer before the test runs
- When
- 90 days of measurement; the result published, pass or miss
Proposed. GrnBit intends to publish the result, pass or miss, with its scope beside it, once the independent engineer has signed it off and those who funded the test have seen it.

GrnBit (Cayman) Holdings, a Cayman Islands exempted company incorporated in 2015. OCTO SI was developed by its founders for the company, which holds it as a trade secret; the founders' confirmatory assignment to the company is not yet executed.
Nothing is mining, GrnBit holds no Bitcoin, and no revenue is earned yet.
OCTO SI is simulation-validated, so far only on a digital twin: its edge over stock firmware is not yet measured on live hardware.
The GrnBit SSI Bitcoin Fund SP is a CIMA-registered segregated portfolio, constituted and functioning; its scope update is with CV5. CV5 Capital is Platform Manager and fund manager of record; GrnBit is investment manager, a Registered Person under SIBA; the offer is the Fund's alone.
OCTO SI's first live test: 13 mining machines in three arms and four GPUs as a calibration control at a related-party site in Oklahoma, pre-registered, independently metered and attested; the result published, pass or miss. Proposed.
Before any plant, Recycle & Refine Co, S.A., to be GrnBit's own operating company in Panama, held through GrnBit Panama (in formation), is proposed to take majority stakes in established Panamanian recyclers, each run by its own management with OCTO SI joining it. Recycle & Refine Co is not yet formed and has signed nothing.
OCTO SI is licensed to miners only after a controlled 90-day measurement on mining machines, attested by an engineer with no interest in either party.
The first 150 t/day line is the demonstration plant; its tonnage is to be under binding agreements after the environmental study.

The future GrnBit is working toward
A waste-to-energy eco-park: a town's waste, sorted for value and turned into power used on site, inside a native forest
A town's waste goes to a dump.
An eco-park, not just a plant: what has value is sorted out first, the rest is turned into power used on site, and the plant sits compact and enclosed inside a native tree belt planted years before it, with rain gardens and a public side.
Four pieces are under way, at the stage shown; one is open: the funding.
- ProposedThe designA builder's proposal; engineering not yet complete
- SelectedThe technologyA licensor's process; no licence signed; to be proved first on one 150 t/day demonstration line
- Non-bindingThe townsTwo candidate towns under non-binding letters; binding terms follow the environmental study
- OpenThe fundingOnce the plant's price and financing pass stress tests
- ProposedThe operatorThe builder runs the first year, then hands over
The first plant is the demonstration: one 150 t/day line, run and measured until its duty cycle is known, before any second line or larger plant. No plant is built today.
See the eco-park as a 3D conceptual model: simulated, not an operating plant.
Panamá
Primero, recuperar lo que tiene valor
Antes de cualquier planta, se propone que Recycle & Refine Co, S.A., una sociedad panameña mantenida a través de GrnBit Panama (en formación), tome participaciones mayoritarias en empresas de reciclaje panameñas establecidas, cada una operada por su propia gerencia y con OCTO SI integrado en ellas.
Propuesto. Recycle & Refine Co, S.A. aún no se ha constituido, no ha tomado ninguna participación y no ha firmado nada.

The founders
Two founders. Shared vision. Complementary strengths. One standard: resilience by design. Built to adapt.
Christopher L. Kaufman
Founder & CEO
Leads the company and its partners, and leads the municipal work in Panamá with Dustin.
Dustin M. Jackson
Founder & CTO
Has built OCTO since 2022 and wrote its draft test protocol; works with Chris on the municipal work in Panamá. The independent engineer runs the test and owns the meters.
