Home›Become a Host
The rig left over from mining, the render farm spinning empty at night, the university cluster asleep between terms, the gaming PC switched off in the evenings. Install one binary, open no inbound port, join the pool. Commission is 15%, payouts land every Friday, your scorecard is public.
Host registration opens in Phase 1. There is no application form today; this section describes the system and the rules being built.
Host section
Who can be a host
You don't need to run a data center. The electricity and depreciation of idle capacity are already charged to you; once you join the pool that line starts moving over to the income side.
Cards sitting on shelves, power and cooling already in place. The only thing you have to do is line up the operating system and the driver; the agent handles the rest. This is the easiest first-class host type.
When a project ships, the farm stops. You open that gap to the pool at night and on weekends, then put the machine into maintenance mode and pull it back the day the next job arrives. A scheduled maintenance window does not lower your scorecard.
Nodes bought with a budget, waiting idle for months between terms. If unused hours turn into income, the lab gains a line item that pays for itself. Internal use always comes first; the pool takes the leftover capacity.
One card, a consumer connection, an owner who uses it in the evenings. These machines are placed on short, interruptible jobs; on Windows they run through WSL2. If you are after serious earnings, booting Linux from a second disk moves the same hardware into first class.
The three promises — from the host side
If your machine fails the health check, the customer's billing stops that second and the job moves from its checkpoint to another host. The same rule applies to you: idle seconds earn nothing. What raises your utilization is your price and your scorecard.
When the customer hits the cap, the job pauses safely and your machine frees up. What you accrued until that moment is settled: the risk of an uncollectible invoice sits with the marketplace, not with the host.
Your earnings accrue by the second; nothing is rounded up to an hour, or even to a minute. A 40-second inference job is recorded as 40 seconds and shows up line by line in the period statement.
These three items are the product's commitment, not measured past performance. The host agent, the registration flow and weekly payouts belong to Phase 1; they are not running in production today.
Map of the section
Becoming a host is an operating decision, not a marketing one. The pages below cover everything you need in order to make that decision — limits and negative answers included.
Which operating system is fully supported, which is limited, which is not supported at all — with the reasoning. One-line install on Linux, WSL2 preparation on Windows, why macOS is out.
Supported cards and the VRAM floor, the CPU/RAM/disk ratio per card, network and upload speed, power stability, and what happens while you are using the machine yourself.
You set the price, commission is 15%, the remaining 85% is yours. Worked examples for three configurations, electricity cost as an input, the payout day, and what we do not promise on the tax side.
Four metrics, published weights, one score. How the score drives placement, how to raise it, and what happens to the computed value when we intervene by hand.
On-site audit, SLA commitment, access to enterprise workloads, higher utilization and a wider price band. Application steps. Opens in Phase 3.
Can I see the customer's data, when do I get my machine back, who pays for electricity, how many machines can I add, what happens if I want to leave — thirteen questions, short answers.
A quick sense of the numbers
The arithmetic is not complicated. Monthly gross = your list price × hours worked in the month. Commission is 15%, the rest is yours. Electricity comes out of your pocket, so don't decide before putting your own kWh price into the equation.
Illustrative calculation: 30 days, uninterrupted operation and a 60% utilization assumption. Real earnings vary with your price, your region, your scorecard and demand; this is not measured revenue.
Where we stand
Kaldera is at the company-formation stage and the product is in Phase 0. Every rule written on the host side is designed; none of it is running yet. The list is here so the distinction stays clear.
Component-by-component status: Status. Architecture and isolation commitments: Security.
Get started
Read the setup page first: find out which class your machine's operating system falls into. Then run the earnings calculation once against your own kWh price. If the numbers hold, get in line.
Host registration opens in Phase 1; there is no application form yet. and the earnings examples are illustrative.
