Cuckoo Cycle: a graph-theoretic proof-of-work system
Abstract: We introduce the first graph-theoretic proof-of-work system,
based on finding cycles in large random graphs.
Such problems are arbitrarily scalable and trivially verifiable.
Our implementation uses 1 bit per edge, and up to 1 bit per node.
We hypothesize that using significantly less causes superlinear slowdown.

Note: previous memory hardness claims invalidated and adjusted by new preprocessing step reducing memory 32-fold.
