Three common misconceptions about zero-knowledge proofs: 1️⃣ "It's all about privacy." Privacy is just one use. The bigger one is verification: proving a computation was done correctly without anyone having to redo it. Most ZK running in production today is there to make results checkable at scale. 2️⃣ "It hides everything." You choose exactly what to reveal and what to hold back. Prove you're over 21 while showing nothing else, or prove a balance covers a loan without ever revealing the number. Selective, down to the detail. 3️⃣ "It's too slow to be real." That was true for years. Today a zero-knowledge proof of an entire Ethereum block finishes in seconds. The engineering finally caught up to math that's been around since the 1980s. We walk through all of this properly, from blockchain basics up to real-time proving, in our From 0 Knowledge to Zero Knowledge series. Start from part 1 👇
