When you create a wallet on Trezor, it generates a unique address for you to receive funds.
The process of generating a wallet address on Trezor involves several steps. First, the device derives a private key from a random seed. This private key is responsible for controlling the ownership and access to your funds. It is crucial to note that the seed, which consists of a sequence of words, must be kept safe and securely stored as it is required to restore your wallet in case of loss or damage to the device.
Once the private key is derived, Trezor uses a mathematical algorithm to convert it into a public key. The public key is a unique identifier associated with your wallet, allowing others to verify that transactions are indeed coming from you. However, despite being called a “public” key, it does not disclose any sensitive information related to your private key.
To enhance the security of the wallet address, Trezor then hashes the public key. Hashing is a one-way function that transforms data into a fixed-size string of characters, making it virtually impossible to reverse-engineer the original input. This process protects sensitive information and ensures the integrity of the wallet address.
Next, Trezor adds a network byte to the hashed public key. This byte distinguishes the network on which the cryptocurrency operates, such as Bitcoin or Ethereum. It helps prevent address collisions between different networks and ensures that funds are sent to the correct destination.
After adding the network byte, Trezor encodes the resulting data using Base58 encoding. Base58 encoding is a format that eliminates ambiguous characters, such as uppercase “I,” lowercase “l,” and number “0,” which can cause confusion in reading and typing wallet addresses.
To further enhance the security and eliminate potential errors during transactions, Trezor appends a checksum to the encoded wallet address. The checksum is a short piece of data computed from the wallet address and acts as a verification code. It helps detect and prevent typing mistakes, ensuring the funds are sent to the correct wallet address.
Finally, Trezor completes the process by presenting you with the finalized wallet address. This address is a unique combination of the network byte, encoded public key, and checksum. It provides a secure and convenient way to receive funds to your Trezor wallet.
Understanding how Trezor generates wallet addresses can provide reassurance in the security and reliability of the device.
