Three decisions, each made for the person taking the payment.

1. A node small enough to run yourself

   Fast chains produce so much data that shops end up trusting someone else's API. At one block every five seconds the chain grows slowly, so a merchant can keep a verifying node on an inexpensive server and ask it directly whether they were paid.

2. Parallel blocks are merged, not thrown away

   When two miners find a block at the same moment, a plain chain discards one. The GHOSTDAG protocol keeps both and puts them in a single agreed order, which is what lets the block time be short without wasting honest work.

3. Mining bound by memory, not by custom chips

   The proof of work is called Hallmark. It is FishHash, the memory-hard algorithm built for Iron Fish, with a seed of our own. Every hash makes random reads across gigabytes of memory, the thing consumer graphics cards already do well. That limits what custom chips can gain; it does not rule them out.

Take a payment with a few lines of code.

// Talk to a node you run
const client = new IMoneyClient({
  nodeUrl: 'http://127.0.0.1:18556'
});

client.openCheckoutModal({
  merchantAddress: 'imntest:q...',
  amountImn: '12.5',
  invoiceId: 'INV-1042',
  level: 'included',
  onSuccess: (payment) => {
    markOrderPaid(payment.invoiceId);
  }
});

Every coin is mined. The schedule is fixed in the code.

The reward halves every four years, four times, and then stays at 0.3125 IMN per block for good, so miners are always paid to secure the network. There is no premine and no share for the developers.

A test network is running. Here is exactly how far along it is.

The coins on the test network have no value and the chain can be restarted. There is no main network and no coin to buy. Anyone offering IMN for sale today is not us.
