What is a Bitcoin wallet?

The purpose of a Bitcoin wallet is to store your crypto assets outside of exchange platforms, which do not offer guarantees in terms of security against potential attacks.

Definition of a wallet

A wallet is a tangible or intangible medium that allows you to store your cryptocurrencies, manage them and carry out transactions. This wallet works thanks to two encryption keys:

  • A private key, which acts as a signature to confirm the placing of a transaction order on the network. This is the most important security key, which you should never communicate;
  • A public key, whose role is to precisely verify the quality of the signature. Shared when you buy your Bitcoins, it represents your address on the blockchain.

To go further: the concept of key results from the asymmetric key cryptography device based on the ECDSA algorithm (Elliptic Curve Digital Signature Algorithm).
