Following close on the heels of Jacob Kobernik’s thorough investigation of bitcoin, we will review the Zerocash whitepaper which picks up where all the anonymity concerns of bitcoin left off. Zerocash “provides a full-fledged ledger-based digital currency with strong privacy guarantees” by leveraging recent advancements in the zero-knowledge Succinct Non-interactive ARguments of Knowledge (ZKSNARKs).
