The crypto card is not a stripping for launch: misunderstanding of "secure infrastructure off-chain" in the world #Web3

In the crypto community, there is often an opinion that "the crypto card is a stripping for launch." Some believe that blockchain itself is already encrypted, and installing a hardware crypto card is just an unnecessary measure; others directly say that this is a "false demand" created by manufacturers to increase prices. But if you really think so, you may have underestimated the complexity of Web3 security — the crypto card is not an excessive design, but rather a key infrastructure moving from "trust on-chain" to "security off-chain," and a necessary choice in the context of evolving attacks and defenses.

Cryptographic technologies of blockchain (such as SHA-256, elliptic curve algorithms) address the issues of "data immutability on-chain" and "transaction confirmation," but they cannot control how your private key is stored off-chain.

The crypto card must solve the main issue — "how to store the private key off the network so as not to lose or steal it" — and this problem is the Achilles' heel #Web3.
