Practical knowledge can seem boring until you run into trouble and realize how valuable it is.
This lesson’s topic: zero-knowledge proofs.
ZK Rollups use zero-knowledge proofs to let the Ethereum mainnet verify that a batch of transactions was processed correctly.
When you see a project claiming to “use ZK technology,” first ask exactly which part of the process it’s used in. Don’t focus on the buzzwords alone.
$ZK is the token of the ZK Rollup network ZKsync.
