I still don't understand.  Do you mean entry credits?  those are created by users burning factoids.  when servers need them for varoius sundry tasks, they burn factoids too.  there are only 3 chains that are privaleged in the system which can only be written to by the federated servers, and consequently do not need entry credits.  they are the:

Factoid Chain
Entry Credit Chain
Administrative Chain

The Factoid chain only holds valid factoid transactions.

The Entry Credit chain holds all the Entry Commits and Chain Commits.  These are the payments that users make when they are paying Entry Credits to place data into the various user chains.   It also hold links to Factoid transaction IDs which purchase Entry Credits.  These increase an EC balance, where the commits decrease the balance.

The Admin chain holds the signatures for the previous block headers, as well as keeping track of who the Federated Servers are.  



Once we get m2 up and running we would love to have more nodes on the network.  More nodes will keep it robust and help protect the network from attack.
