    So, at the end of the day, in the world of Bitcoin, opening an account is randomly generating a private key, then working out the public key, and then counting the addresses. Bitcoin uses an encoding called Base58 that converts binary numbers to letters and numbers in case, so the private key and address we see are a string of characters. What is the use of this private and public key? The private key is a bit like a password, but unlike a password, it can be used to encrypt transaction information, and the resulting private key can only be decrypted by the public key corresponding to the private key. The public key can be disclosed to others, the private key must not be disclosed, the private key can be used with the public key, used to prove identity, this process is also called signature, only with the private key signed transactions, can be recognized and recorded in the Bitcoin block, but the private key itself does not need to be disclosed. Import the private key to recover the Bitcoin wallet, from this point of view, the private key is equivalent to the account plus password. Because the private key is neither easy to remember nor easy to write, people designed a mn need to randomly generate a private key, the root private key corresponds to a set of monemone words, monemnoty is generally 12 words. Then, using the root private key according to a certain algorithm, the private key of each currency can be generated, but also on the basis of each private key according to a certain algorithm to continue to generate the private key, child private key, Sun private key ... Children and grandchildren are endless. This allows you to master many private keys by simply remembering a set of mnjectives. When we use some Bitcoin wallets, we tend to let you set a password, which is not a private key, it is equivalent to the wallet's administrative password, the role is to authorize the call of the private key to sign. So keeping your private key or monemone is the first step into the digital currency world.

    Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Devi Security Lab. Hackers broadcast messages to the Electrum client through a malicious server, prompting the user to update to v4.0.0, and if the user follows the prompt to install this "backdoor-carrying client", the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs worth about $11.6 million had been stolen from phishing attacks that faked Electrum upgrade tips. DeViable Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet are requested to update to the latest version of Electrum 3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the link in the prompt to avoid asset losses.
