Among the many solutions for protecting digital assets, the "cold wallet" has gradually demonstrated its importance and necessity as a highly secure storage method. This article will delve into the definition, working principles, advantages and disadvantages, usage scenarios, and how to choose the right cold wallet, in order to help users better protect their digital assets.
Cold wallet
A cold wallet is a method of offline storage for digital currencies that is not connected to the internet, thereby effectively preventing hacker attacks and other cybersecurity threats. Cold wallets typically come in two forms: hardware wallets and paper wallets.
Hardware wallet
A hardware wallet is a dedicated physical device used for securely storing private keys and digital assets. When connected to a computer or mobile phone, it establishes an encrypted channel to ensure the security of online transactions. Common hardware wallet brands include Ledger, Trezor, and others.
Paper wallet
纸钱包则是通过打印或手写的方式保存私钥和公钥，完全不依赖任何电子设备。纸钱包的优势在于完全脱离网络，避免了网络攻击，但在使用上也存在一定的不便，如易损毁、遗失。
