Get started Reference

A tally counts ballots. A settle weighs them: each voter listens to the voters it trusts and moves toward their opinion. Where that iteration stops is the group’s position. ljos-consensus is the discrete model as one binary: ballots and trust rows in, shares and rounds out. It can also write the inputs for the Seldon opinion-dynamics engine and read its output.
