Tark Wallet: How important is the private key?


The private key determines the ownership of the blockchain asset, and the loss of the private key is equivalent to losing everything.

When it comes to digital wallets, security is a topic that can never be bypassed.There is safety, there is money; when safety is poor, money is risky; there is no safety, there is no money. Today, we will analyze how to guarantee security from the point of view of private key, a part of digital wallet security.

First, the private key needs to be sufficiently random. The private key is actually a random number, but the concept space of this random number is relatively large - 256 power of 2. The private key is generally randomly generated by the wallet. What we want to emphasize is that the generation process of the random number of the wallet must be really random, which is very important.

Computer-generated random numbers are generally called pseudo-random because they have a deterministic algorithm that works with a seed (such as time) to produce some seemingly random results, but in reality anyone can master the algorithm and master the seed. It is possible to get the same result, which means that it is predictable. For example, bitcoin, there are 256 power of 2 of drawers in the universe, generating a bitcoin private key, which is to randomly select a drawer to put money in.

Because this number is large enough, all the people on the planet generate a private key every second and will not repeat, so this mechanism is relatively safe. At the end of 2014, Bitcoin wallet blockchain.info had a serious random number problem in a version upgrade, it was the repetition of the R value that led to the loss of the coin. It was soon discovered by a white-hat hacker, and two and a half hours later the problem was fixed. But during that 2.5-hour period, more than 200 bitcoins with more than a thousand addresses were lost, so random numbers were a "life-line" in the blockchain.

Second, the private key is not connected to the Internet. Because now hackers are almost pervasive. Don't mention that some civil systems and construction, even the US military's very strict security system, and some hackers can even invade. Therefore, in order to truly achieve complete security, it must be not connected to the Internet, and it is not connected from beginning to end.

Tark wallet has the advantage of offline signature, avoiding private key to connect the network and reducing the risk of theft. Each transaction involves the question of signature confirmation. The Tark wallet user holds the private key, and the transaction is not connected to the private key. The transaction is safer. Tark wallet automatically opens the never-on networking mode during idle state, builds transactions and signatures at the cold end, connects the network and broadcasts transactions at the hot-end, creating a strong protection shield for the token assets, completely eradicating network hacking and resisting asset risks caused by various reasons.

Third, the private key must not be lost. The loss of private key is the cause of the most loss of assets. The private key is to be copied on paper, and copy it right, and then placed in a place that will never be forgotten. And don't put the private key and wallet together.

As mentioned in the opening paragraph, the private key is only a small part of the digital wallet security field. Tark wallet's efforts in security construction have never been relaxed - the world's first dual-form cold wallet security protection model to protect the user's token assets; with advanced technology surpass the global main stream circulation token asset wallet, the introduction of Silicon Valley’s technology innovation and development of multi-person collaborative management functions, greatly reducing the safety factor of the risk of the user's token assets.
