Zero-knowledge is easy or the ultimate how-to article

The author, Nikita, CTO of Big Whale Labs, argues that zero-knowledge (ZK) products can be built without a computer science or math degree, and that most ZK tutorials teach far more than a builder needs. He says he found he did not need 95% of what tutorials cover, and that deeper study can wait until a specific issue arises. The article walks through a starter repository (zk-starter) that handles configuration, and explains the FactorChecker and EdDSAChecker Circom circuits. It states that constraints drive proof cost, that fewer constraints are better, and that a pot16 powers-of-tau file is used by default, with anything above 19 described as unfeasible on mobile.
