bitcoin is actually a string of data in the bitcoin network. Where should this data be stored? Just as our bank cards and cash can be stored in our wallets, bitcoin also has its special wallet, which is bitcoin wallet. In fact, bitcoin wallet does not contain bitcoin. Bitcoin wallet is a database composed of private key and public key. Bitcoin itself is stored in the blockchain. Users sign the transaction with their private key to prove that they have the transaction. Blockchain is a huge database ledger, so this transaction will remain in the blockchain database, and no one can tamper with it

with & lt; Multi signature & quot; With the application of multi signature technology in the field of wallet, a multi signature wallet emerges as the times require& ldquo; Multi signature & quot; What do you mean? Usually, a private key corresponds to a bitcoin address, and the assets on the address of bitcoin can be transferred with this private key. The process of encrypting with private key is signature. Multi signature means that before an address uses bitcoin, it needs multiple private keys to sign

in other words, a transaction needs two to three or more private key signatures to process bitcoin in the address. In this way, the security of our assets is greatly improved, and it is also applicable to the bitcoin transfer of institutions, without affecting its speed. Generally speaking, a light purse is enough for beginners, and it is convenient and easy to use. But we must pay attention to the security problem and keep the private key well
