What's address metadata hashes?


By lulalala - 9 Jan 2018

While reading about sweeping in the official documentation:


I see these initial variables:

  const addresses = [
  // Address metadata
  // hashes represent any unresolved sweeps
  const metadata = [
   {security: 2, keyIndex: 1, user: 'Chris', hashes: []},
   {security: 3, keyIndex: 2, user: 'Dom', hashes: ['']}

But what are `hashes` actually? Do I obtain those from another API or do I compute it somehow? Why is one empty array while another one an array of empty string?
