Nockchain ($NOCK) is presented as a new Layer 1 blockchain aiming to be "programmable sound money" with ZK privacy features, similar to how Ethereum ($ETH) relates to Bitcoin ($BTC), building on Zcash's ($ZEC) privacy foundations. Its mainnet is set to launch in 2025, offering programmable features like rollups and DeFi integrations via its zkVM. Investors should note the early stage of $NOCK with execution and adoption risks, contrasting with $ZEC's established history since 2016.
