2020 is destined to be a turbulent year. The epidemic is raging, the market is ups and downs, people are worried, and the theft of the exchange adds fuel to the fire. In fact, the number of exchanges stolen is increasing year by year. The theft of the exchange is mainly divided into several types: the first is the vulnerability of the smart contract of the project itself, which cannot be interfered by human beings, but it is actually the most tragic situation for users, project parties and the exchange; The second is that the private key is stolen, and the private key of the switch that stores the user address is stolen. As we all know, if users don't keep their private keys well, your assets are basically gone; The third situation is that the exchange steals secrets internally, and there will be some such situations. For example, the exchange reveals some stolen information to users. These TOKEN may be digested by themselves, or they may be the profit means of some small exchanges.

No matter what the result or the fact, it is a wake-up call for us. The exchange is not very safe!

Under normal circumstances, the exchange will reserve some coins in the hot wallet for circulation, and the rest will be deposited in the hardware (cold) wallet. For long-term hoarded assets, it is generally chosen to bring back hot wallets from exchanges for preservation, while hardware (cold) wallets will be used for long-term immobile assets, so it is very important to choose hardware wallets with high security and convenient use.

Why is the hardware wallet safe?

Offline storage of private key-The hardware wallet uses a special encryption chip to store the key, which is isolated from the Internet, and the key cannot be directly derived from the wallet, thus cutting off the way for hackers to invade through the network, so that even if the computer or mobile phone using the hardware wallet is infected by viruses or hackers, the security of the key can be guaranteed without causing asset losses.

System integrity protection-refers to the hardware wallet system can protect its key components from illegal tampering, and any system may be attacked. When an attack occurs, the hardware wallet with system integrity protection ability can find the attack and make corresponding security response.

How to choose a hardware wallet?

Price is not the main factor, the more expensive the better, and the cheaper the better. The main purpose of buying a hardware wallet is to ensure the safety of assets. In addition to price, we should pay more attention to the functional attributes of hardware wallets, and asset security is the most important.

Choosing a strong team, because the blockchain field is developing too fast, and there are too many products and enterprises that are eliminated from the middle, it is obviously very important to know the team and company while choosing products and carefully buy hardware wallet products, which can avoid some unnecessary troubles and losses in the future.

BEPAL is the first blockchain company in China to make hardware wallets. The hardware wallet produced is a digital asset refrigeration device specially designed for mobile payment scenarios and novices. Built-in financial bank-level EAL5+ security chip, private key offline storage, offline transaction signature, has a good user experience, which can protect the security of your digital assets. At the same time, it supports digital asset management such as BTC, ETH and EOS, and has successfully launched BEPAL PRO S, Q and Touch series security hardware.

Everyone needs a hard-core hardware wallet

The main advantage of BEPAL hardware wallet is security. In order to make the user's operation safer and more convenient, we have made great efforts in security. Bipai has many well-known teams as partners, and at the same time, it has implanted security chips in product design, including core technologies such as anti-violent disassembly and anti-hacking.

Take our two main hardware wallets as an example. BEPAL PRO S mainly provides security for users from the aspects of product fluency and natural hot and cold signature algorithm. It follows the strong security functions of RFC6979, such as strong random number, encrypted transmission of non-electromagnetic wave channel information, multiple encryption protection of private key seeds, hardware protection of encryption seeds, mastering private key seeds with one hand, using encryption seeds without contacting the Internet, fast and convenient account recovery, offline storage and so on.

BEPAL Q is a hardware wallet made of three-level security chips by BEPAL. Compared with other brands of hardware wallets at the same price, BEPAL Q is one of the few wallets that can be operated on the mobile side and also support the operation on the PC side. From the security point of view, just like other brands of hardware wallets, we have also implanted security chips and internal technologies to prevent violent disassembly and hacking. We have a built-in security system. When we recognize hardware debugging, brute force cracking and multiple password attempts, we will directly erase the memory and encryption seeds, and hackers will not be able to obtain the underlying private key seeds. In addition, information encryption processing, address conversion and transaction signature information encryption processing, if tampered with or illegal, will not be able to sign. In order to ensure the safety of assets, the (HD wallet) currency management adopts a hierarchical certainty scheme, that is, a single mnemonic seed password (joint payment password) can manage all blockchain assets.

Therefore, from the perspective of security, the last safe place in the hardware wallet world is the blockchain. However, security is always relative. Whether it is a hardware (cold) wallet or a hot wallet, the biggest risk factor is people. It is a compulsory course for each participant to master wallet knowledge and choose the storage method of encrypted assets that is most suitable for their own situation.
