Editing Permissioned resource coins (section)

=== Generating an initial white list ===

To setup the resource coin, one must generate an initial list of hosts who will provide storage space on the network. These hosts, called “farmers” will consist of individuals who have verified identities via Civic and who have deposited a certain amount of resource coins to use as collateral.

This helps to prevent wealthy people from compromising the system and improves decentralization, but any other algorithm can also be used [insert your favorite proof-of-stake algorithm here] to generate the initial list.

<pre>bonds = {}
farmers = [
    {&quot;pub&quot;: &quot;alice&quot;, &quot;gb&quot;: 10},
    {&quot;pub&quot;: &quot;bob&quot;, &quot;gb&quot;: 10},
    {&quot;pub&quot;: &quot;eve&quot;, &quot;gb&quot;: 10}, 
    {&quot;pub&quot;: &quot;malory&quot;, &quot;gb&quot;: 10}
]

# Todo: allocate this to a pending pool and
# when pool is large enough -- shuffle it randomly
# before adding to farmers to prevent Google attacks
def add_new_farmer(pub, gb):
    if bonds[pub] &lt; 100:
        return

    info = {
        &quot;pub&quot;: pub,
        &quot;gb&quot;: gb
    }
    
    farmers.append(info)</pre>
The registration algorithm can be as simple or as complex as needed. Here, the code is checking to see that a new farmer has made a large enough collateral deposit to impose higher costs on Sybil attacks. A more complicated function would allow farmers to increase the amount of storage space they can advertise based on reputation and other factors.
