Claim 0:
1. A computer implemented method comprising:
devising a crypt for pre-distribution of tokens to facilitate electronic communication sessions in a non-obligatory network, the tokens being keys facilitating computationally solving the crypt;
distributing the tokens to member nodes of the network, wherein each member node receives a respective unique token of the tokens, in which each token of the tokens is distributed to only one member node;
based on a request from a delegate node of the network for brokerage of a session between the delegate node and a supplier node of the network, where the supplier node is one of a collection of supplier nodes offering a resource requested by the request and communications of the session are encrypted based on the token distributed to the supplier node, creating, for each potential supplier node of a plurality of potential supplier nodes of the network, a respective individual puzzle for the potential supplier node based on the devised crypt, and sending the individual puzzle to the potential supplier node;
receiving, from each of one or more potential supplier nodes of the plurality of potential supplier nodes, a respective result obtained by the potential supplier node from solving the individual puzzle using the token distributed to the potential supplier;
identifying, based on the receiving, one or more candidate supplier nodes of the one or more potential supplier nodes as a potential supplier for the session with the delegate node; and
identifying to the delegate node the one or more candidate supplier nodes for the session with the delegate node.
