Iron fish is a level-1 blockchain aim to solve this by providing privacy on all blockchain tech layers while solving the ease of access drawback of other existing privacy blockchain. Iron fish encrypted all of the data on-chain (account balance, transaction detail, etc.) and uses ZK-SNARKS (Succinct Non-Interactive Arguments of Knowledge) in verification process. For example, to proof that a sender possesses the funds they want to transfer without revealing the account balance or attesting the validity of transaction details without revealing transaction amount to the validators. In order to view the actual data or authorize a transaction on Iron Fish, a secret key is needed. There are different types of secret keys for specific purpose such as spending and viewing, but all of them are derived from a single secret key (think of it as a master key).
