Conflux synchronizes data by unique content-addressable identifiers. It does this by representing the entire set of identifiers with a polynomial. The difference between the databases is represented as a ratio of these polynomials. However, the polynomials are very large, since they represent every identifier in the database. The difference between databases is communicated by evaluating the difference ratio at a number of constants. Through the magic of rational function interpolation, the difference ratio can be reconstructed from these data points.

This algorithm is described in the papers, "Set Reconciliation with Nearly Optimal Communication Complexity" and "Practical Set Reconciliation".
