[Analysis] You can now prove a whole blockchain with one math problem - William Foxley

The Electric Coin Company (ECC) says it discovered a new way to scale blockchains with “recursive proof composition,” a proof to verify the entirety of a blockchain in one function, explains CoinDesk's William Foxley. ECC engineer Sean Bowe said recursive proof composition is the result of years of labor, on which he almost gave up three separate times. Bowe’s work is similar to bulletproofs, another zk-SNARK that requires no trusted setup. In fact Bowe explained his work as "recursive bulletproofs." After summarizing the technical details of his work, Bowe spoke practically on where his discovery ranks with other advancements:

“Where does this stand in the grand scheme of things in cryptocurrency? It’s a cryptographic tool to compress computation… and scale protocols.”
