The Bitcoin Express · arriving Galtland

Every door
is a device.

Lights, locks, drones, machines. Pay to use any of them, with the owner's permission, from anywhere. One channel, thousands of commands, each one sealed inside its own payment. Stop paying and it stops.

How it works

The payment is the permission.

Most connected things ask who you are, check an account, then decide. On Open Line a device asks one question: has this command been paid for, on the owner's terms? If it has, it acts. If not, it doesn't.

01 · THE OWNER

Sets the terms

A device is a line with its own key. Its owner publishes what it does, what it costs per second of use, and the limits it keeps whatever anyone pays: how high, how far, how long, who may use it.

02 · YOU

Pay as you use it

You open one payment channel to the device and pay a few seconds at a time. Every command you give travels inside the payment that pays for it, sealed so only the device can read it.

03 · THE DEVICE

Stops when the money does

Stop paying and it stops, and makes itself safe: the drone flies home and lands, the rover drives back, the door locks. You pay only for what you used; the rest of your lock comes back.

One step further

Paying a machine is not new.
Permission inside the payment is.

People have already paid robot cars over the air and topped up machines by the minute. Open Line goes further: the payment carries the command, the device enforces its owner's rules itself, and nobody in the middle holds the money.

Pay, then command

  • A payment unlocks access; commands travel separately and anyone holding the session can send them.
  • An account or a server in the middle decides who may use the device.
  • A platform holds the money and settles later.
  • Stop paying and the device finds out when someone tells it.

Open Line

  • The command is the payment. No valid payment, no command. Nothing else can steer it.
  • The owner's limits live in the device. Paying more never buys past them.
  • Straight to the device's own key. No account, no custody, from any site or app.
  • Stop paying and it knows at once, holds for a few seconds, then makes itself safe.
  • Proof on chain of exactly what was commanded and paid.
Galtland

Every door on the island is a device.

The Bitcoin Express arrives at Galtland, an island of 64 houses. Each house's door is a line of its own, and its owner decides what it does and what it costs, for visitors from any world.

KnockA paid hello rings the owner, wherever they are.
EnterThe owner's terms open the door: by the minute, by invitation, or not at all.
Light it upLamps, signs and screens paid per second by whoever is watching.
Fly inDrones and cameras that answer only to whoever is paying, inside the owner's limits.
Live now

Try it before the train leaves.

Every one of these is a real line on this host, paid over a real payment channel. The machines are simulated; the money is real, and small.

For builders

Your device, on a line.

If it can hold a key and take a command, it can be paid by the second, by the command, or both, by anyone you allow, from any app.

  • A signed offerThe device publishes its price, its unit of time, the reserve it keeps back to make itself safe, and what it does when the money stops.
  • Commands sealed in paymentsFixed-length, encrypted to the device, opened only after the payment checks out. A relay can carry them but cannot read or forge them.
  • Limits that money cannot buy pastCeilings, fences, speed and time: kept by the device, recorded in the running hash.
  • Settled straight to the deviceEarnings land at the device's own per-call addresses and sweep to the owner. No platform account in between.
