DePIN: Rooftops That Rent Out Their Airwaves, Paid in Tokens

In January 2026, a mobile phone network booked twenty-four million dollars in revenue in a single month. It is called Helium Mobile, runs on deals struck with carriers such as AT&T and Telefónica, and counts its users in the tens of thousands. Its peculiarity: it has built almost none of its own antennas. More than 376,000 access points have been plugged in by ordinary people, on rooftops, window ledges and garden poles, in exchange for tokens.

The idea travels under an acronym, DePIN, for decentralized physical infrastructure networks. The principle is quick to state: instead of a carrier deploying billions in equipment, strangers install the hardware at home and earn cryptocurrency when the network verifies that their device is delivering a real service. Wireless coverage, file storage, computing power, weather sensors, street mapping: the same mechanism shows up everywhere. And behind the promise of a small income sitting on your roof lies an older question, about who owns the infrastructure that connects us.

A box on the roof, tokens in the account

The act is simple, almost domestic. You buy a box, plug it into your home internet, set it up high, and it begins offering a slice of wireless coverage to the neighborhood. When a phone or a sensor passes through it, the protocol logs the event and credits the host. On the most powerful outdoor setups, the guides promise up to 400 dollars a month, split evenly with the network. The hardware works while you sleep.

The comfort lies in that quietness. No daily errand, no attention required: the device runs on its own, and the income arrives in the background. For anyone with a good spot, an open terrace, a tall building, a busy street, it is an asset that asks for nothing but electricity and a connection already paid for.

There is also, beneath the arithmetic, an appealing idea: to own a piece of the network rather than merely rent it. The traditional carrier bills you every month; here the infrastructure belongs to you and pays you back. Helium's slogan, "own the air," captures the reversal. On paper, the individual stops being a mere subscriber and becomes a paid link in the system.

The same mechanism, from Wi-Fi to sensors

The sector has grown fast. By 2026 it counts more than two hundred active projects and a combined value above forty billion dollars. Some networks have seen their real revenue, the kind that comes from actual customers rather than speculation, jump by several hundred percent in a year.

The uses reach well beyond telephony. People rent out the free space on their hard drives to store encrypted files; others lend the power of their graphics cards to train artificial-intelligence models; cars fitted with a camera map the streets and are paid by the filmed kilometer. Each time the pattern is identical: idle hardware, proof that the service was actually rendered, a reward in tokens.

What changes is the scale of the effort asked. Plugging in a box is weekend tinkering; putting your car or your servers to work means real commitment. But the spirit is the same: to turn a resource already present, a roof, a connection, a little unused silicon, into a source of income, without going through a large company.

Costs in euros, earnings in a currency that floats

The catch is arithmetic. The host pays for hardware, electricity and a subscription in hard currency, fixed and very real sums; the reward comes in tokens whose price climbs and falls without warning. In May 2026, Helium's token was worth about 0.93 dollar. An ordinary residential setup often produces between 0.1 and 5 units a month, which in some months means a few cents. The box, bought for several hundred dollars, can take years to pay for itself, if it ever does.

The danger has a name in the field: the spiral. When the token's price drops, running the hardware turns unprofitable; hosts unplug; coverage degrades; real customers leave; the token drops further. As long as the reward comes mainly from minting new tokens rather than from paying customers, the network can look thriving while it merely feeds on itself.

This is the deep flaw of these networks: the distributed reward draws thousands of contributors, which paints a picture of success, while real demand stays thin. Many put up an antenna for the token, not because a customer is waiting for coverage. The promised autonomy then rests on a financial bet as much as on a service.

Who really owns the network?

Then comes the subtler matter of dependence. The host owns the box, but not the rules. It is the protocol that sets the rates, the emission schedule, the conditions for validation, and these parameters change by vote or technical decision. One adjustment, and yesterday's income halves. You own the hardware and rent the rules.

There is also the part of yourself you expose. A sensor, a mapping camera, an access point records passages, positions, flows. Decentralizing the infrastructure does not necessarily decentralize the gaze cast on what it captures. Owning a piece of the network is not the same as controlling what it watches.

Still, the founding intuition holds. That a roof, a connection, a half-empty hard drive could earn a place in useful infrastructure, without passing through a single carrier, is far from absurd, and some networks are starting to serve real customers. The promise turns solid the day the pay comes from usage rather than emission, when the individual is paid because someone needs them, not to inflate a chart. Until then, the box on the roof is less a quiet income than a wager: on the value of a token, and on the moment the network stops paying itself with its own currency.
