In the crypto circle, the idea that 'encryption cards are like taking off your pants to fart' is not uncommon. Some believe that the blockchain itself is encrypted, and adding a hardware encryption card is just unnecessary; others bluntly state that this is a 'false demand' created by manufacturers for premium pricing. However, if one truly thinks this way, they may underestimate the complexity of Web3 security—encryption cards are not redundant designs; rather, they are a key infrastructure that extends from 'on-chain trust' to 'off-chain security', and are an inevitable choice under the evolution of offense and defense.
To understand the value of encryption cards, one must first break a core misconception: blockchain encryption does not equal the security of private key storage.
