It was reported that the forged crypto wallet did not create a new wallet by generating a public address and private key - which is necessary to securely send and receive digital currency - but only showed the attacker's public address and did not have access to the private key. Considering that the application generates their public address, the user deposits the funds in the wallet, but the private key cannot be withdrawn because it is a cybercrime.

In fact, cryptocurrency custody only needs a "private key", who has mastered the private key, you have mastered your wallet property, so your private key must be kept well.

Digital asset wallet is essentially a tool to store the private key, the security of the private key is very important, in order to achieve the ultimate security, there is no network of cold wallet, so it can be divided into cold wallet and hot wallet according to whether the wallet is connected to the Net.

Wallet address: The so-called wallet address is the same as our bank card number, each person can have more than one bank card, so the wallet address can also have more than one. But like a bank card, a bank card has only one password, and a wallet address can only correspond to a private key. Public key: It is a cryptographic concept that is inferred from the private key. The algorithm for exposing keys is an asymmetric encryption algorithm that has two keys: the public key and the private key. Data encrypted with the private key can be decrypted with the public key and vice versa. The wallet address public key can be calculated from the public key: it is a cryptographic concept that is inferred from the private key. The algorithm for exposing keys is an asymmetric encryption algorithm that has two keys: the public key and the private key. Data encrypted with the private key can be decrypted with the public key and vice versa. The wallet address can be calculated from the public key.

The cryptographic algorithm in Bitcoin We know that the Bitcoin wallet address corresponds to a public key and a private key, and only those who have a private key can access the bitcoins in the wallet, but the private key is secure and cannot be calculated by the wallet address or public key.

The private key is mentioned here, and the wallet address is generated by the private key calculation, and a private key corresponds to an address. (2) Authorized Signature Transactions Each time we make a transfer transaction from our wallet, we are authorized by private key signature before we can issue and complete the transaction. To be clear, whoever owns the private key has control of the digital currency. (3) Recovery Wallet If you accidentally delete or uninstall your wallet, you need to recover your wallet with the private key. In the world of blockchain applications, the assets in your wallet are all stored on the blockchain, the private key is the only proof of your assets in the world of blockchain, and if you have the private key, you have the assets at the corresponding address. If your private key is lost, you lose control of the assets in the chain, and there is no way any platform can help you get it back. So be sure to back up the private key securely.

There is no backup of the private key in the process of central wallet registration, so this address does not belong to you, but to the platform side.

A paper wallet is a paper wallet that prints or copies your private key on paper and keeps it safe. Paper wallets do not have any network risks, but each transaction requires manual private key signing operations, which are more complex.

## Private Key Bitcoin Wallet Checksum.

The private key consists of a 64-bit string. Whoever owns the private key has control of Bitcoin. So the private key is very critical! Be sure to save it! But because the private key is too long, the wallet does not let the user set it up, but the wallet generates the private key itself.

In the blockchain world, no one but yourself can store your passwords, private keys, monems, keystores, imToken wallet companies, so as long as you protect your wallet, your property can't be robbed, which is a centered advantage. But if you don't protect your wallet and lose your private key and monemone, no one can help you get it back.

## Dogecoin wallet address.

A private key is a string of data that gives you access to tokens in a particular wallet. The private key is a password that no one but the address owner can access.

Technically, wallet apps create one or more wallet addresses based on cryptography, each with a key pair: the private key and the public key. The public key is generated according to some mathematical operation of the private key, which corresponds to the private key one by one. The public key is primarily used for external transactions, and the private key is the only document that can prove control over digital assets. The purpose of a wallet is to hold the private key. As long as you have a private key, it means that you have the corresponding token.

Ironically, the plot suddenly reverses: QuadrigaCX Exchange Cold Wallet still shows signs of continuing to transfer money, and is suspected to have no private key at all.
