| '''TREZOR is a hardware wallet providing the highest level of security and convenience for a common computer user.'''
| |
| | |
| Unlike a cold storage (offline storage or paper wallet), TREZOR is also able to sign transactions. That means spending bitcoins is secure without exposing your private keys to a potentially compromised computer.
| |
| | |
| == TREZOR Hardware Design ==
| |
| | |
| TREZOR is a small USB device with a display and two buttons.
| |
| | |
| It connects to a computer via a USB via protocol that allows only to send a transaction template to the device and protects the wallet against malware.
| |
| | |
| The display allows the user to visually verify the payment address and the amount to be sent. In order to proceed the transaction, a physical human interaction (pressing the button) is required.
| |
| | |
| == TREZOR Software Design & Security ==
| |
| | |
| === Backup ===
| |
| | |
| TREZOR uses hierarchical deterministic wallet creation ([[BIP 0032]]) which makes regular backups of private keys unnecessary.
| |
| | |
| When first initialized, a mnemonic code of 24 words, the recovery seed, is created. In case the device gets lost or stolen, the user can recover the entire holdings including transaction history into a new device or other compatible wallet, using the recovery seed.
| |
| | |
| === PIN protection ===
| |
| | |
| A PIN is set by the user during the setup. It protects TREZOR against being used by unauthorized persons. The wallet creators have invented a secure way of entering the PIN that can't be logged and misused.
| |
| | |
| === Passphrase encryption ===
| |
| | |
| Another level of protection is the encryption passphrase which protects the device in case of seizure. Multiple passphrases can be used for plausible deniability.
| |
| | |
| == Using TREZOR ==
| |
| | |
| TREZOR needs an online wallet or a desktop client as an interface that broadcasts the transactions signed by the device to the blockchain.
| |
| | |
| In order to send coins or change the basic settings, the device needs to be connected to a computer with a micro USB cable.
| |
| | |
| In order to receive coins there is no need to have the device plugged in.
| |
| | |
| ===Compatible software===
| |
| | |
| In order to be compatible with TREZOR a software must implement the following standards: [[BIP 0032]], [[BIP 0039]] and [[BIP 0044]]
