Ⅱ What is the difference between a cold wallet and a light wallet
Abstract Cold wallet It is also called offline wallet, that is, a wallet used in an environment without networking. For example, writing private keys or mnemonics on paper, professional hardware wallets, and people making cold wallets using devices that are not connected to the Internet. The advantage of using a cold wallet is security, and the disadvantage is that it is troublesome to trade and create a wallet. Light Wallet (SPV) SPV refers to “payment verification” rather than “transaction verification”. A light wallet is a wallet implemented in a thin client mode. It does not store the complete blockchain, but only saves data related to itself.
Ⅲ What is a cold wallet
In general, a cold wallet is a wallet that stores digital currency offline. Players generate digital numbers on an offline wallet. Currency address and private key, and then save it. The cold wallet is to store digital currency without any network, so hackers cannot enter the wallet to obtain the private key.
Ⅳ I see that many people are using Kushen cold wallet, and now they are considering whether to buy it or not, mainly worrying about its battery, is its battery life OK?
I’m using the Kushen cold wallet now, and I don’t feel that the battery capacity is not enough. Its power capacity is 1200ml, which is a little less, but I don’t need it for other purposes. It’s not like playing games like a mobile phone. , By the way, charging through the computer usb, only charging, the computer cannot communicate with the hardware device.
IV How does cold wallet and mnemonic hardware work
Increase flexibility with trusted mnemonics.
Software cold wallet, different from hardware cold wallet, software cold wallet uses pure software to realize the function of cold wallet. Users need to use two mobile phones, one of which is permanently offline, as a cold wallet to store the private key (mnemonic phrase). The other is connected to the Internet and used as an observation wallet. Software cold wallets and hardware cold wallets achieve the same functions and have similar security levels. But they have some notable differences: software cold wallets can use idle mobile phones without additional hardware; hardware cold wallets transmit data via a data cable or Bluetooth, while software cold wallets scan QR codes.
Trusted mnemonics: Software cold wallets can achieve more thorough trustlessness (that is, no need to trust software developers), and users can prove the absolute security of their wallets by themselves. In asset safety, the first and foremost is the safety of mnemonic phrases. In the security of mnemonics, the first confirmation is the randomness of mnemonic generation. If you’re using a hardware wallet from a malicious hardware vendor (or buggy), you’ve probably fallen for the first step.
When using a software cold wallet, you can choose to trust the software to help you generate mnemonics. You can also choose not to trust the software and generate mnemonics elsewhere by yourself. Therefore, the security of the mnemonic of the software cold wallet is higher than that of the hardware cold wallet.
Software cold wallets are more flexible than hardware cold wallets. Usually software cold wallets can implement more complex functions than hardware cold wallets. The flexibility of the software cold wallet also makes it more advantageous in asset recovery. If your hardware wallet is damaged, you need to buy hardware (same manufacturer) for hardware recovery. With software cold wallets, there is no such concern.
At present, although the main cold wallet products in the market are still mainly hardware cold wallets, they are being impacted by software cold wallets. Hardware cold wallet: Ledger is the most well-known hardware cold wallet solution provider; Trezor is another well-known hardware cold wallet provider; Software cold wallet: Ownbit is the earliest wallet to implement the software cold wallet solution, and also supports the most cold wallet currencies One of the wallets; Parity Signer is an Ethereum software cold wallet produced by Parity; the direction of future development is always to simplify the complexity. More and more cold wallets are being implemented in software.
Ⅵ What is the use of a cold wallet
In general, a cold wallet is a wallet that stores digital currency offline. The digital currency address and private key are generated on the offline wallet, and then stored. The cold wallet is to store digital currency without any network, so hackers cannot enter the wallet to obtain the private key.
VII What are the advantages and disadvantages of cold wallets
Advantages: very safe, suitable for large amounts of virtual currency storage
Disadvantages: inconvenient to create a wallet, transaction Also very troublesome.
Ⅷ If I want to store digital currency, is it necessary to buy a Kushen cold wallet to ensure security?
MeI think it is necessary. Digital currency is easy to be attacked by hackers if it is not stored and protected. You still need to be careful. Using Kushen cold wallet can ensure that the private key will never touch the Internet, which greatly enhances the security.
