Astute readers will notice that a 12-word sequence yields 132 bits-four more bits than is required to reach the 128-bit security standard. Since each word takes 11 bits, we would use 12 recovery words in order to generate a 128-bit seed. Because 2,048 = 2¹¹, making a one-to-one mapping of all 2,048 BIP39 words to all possible 11-bit sequences is simple enough to do: We use binary notation (hence the otherwise arbitrary choice of 2,048) to assign to each word the bit sequence that represents its position in the BIP39 word list. So how do these seeds function from a technical perspective? A seed’s strength grows exponentially with the number of bits it contains-generally either 128 bits or 256 bits.īIP39 pulls from a list of 2,048 words. The beauty of this cryptocurrency wallet system is that, should a user lose access to their crypto wallet, they can simply enter the given seed or its recovery phrase into any BIP39-implemented wallet, where they would regain access to their currency, linking that wallet to that seed’s every transaction.

BIP39-compatible wallets provide a mechanism with which to enter our recovery word list and instantiate our associated keys and addresses on that platform or device.

For the sake of security and anonymity, it is a good practice to never reuse an address from your crypto wallet.Īny crypto wallet can generate or recover private-public key pairs and associated addresses from any seed. An address is the “owner” of currency, and is used to anonymously represent ownership of currency amounts on the blockchain. Such a seed is the basis for creating private-public key pairs, which are used for signing and verifying transactions.Įach private-public key pair generates a single address to be used in inter-wallet transactions. The seed should be kept secret and never shared.

Seed Structuring, Security, and Recovery: The BIP39 Perspectiveįor a crypto wallet to function as intended, a unique and private seed is required. These high-level use cases depend on the associated seed that is created when the wallet is instantiated. Crypto Wallet ManagementĬrypto wallet management refers to a wallet’s creation, recovery, and general function of receiving and exchanging coins. Note: Do not use our example Formosa keys or seeds in any crypto wallet as their publication here compromises their secrecy.

We will then dive deeper into a Python tutorial that shows how to leverage Formosa in security projects. To better acquaint you with Formosa, we will cover the basics of crypto wallet management with a concrete recovery phrase example. Users can move from theme to theme with no risk to their existing keys. Formosa is compatible with BIP39, improves security, and features a selection of themes for users to choose from. But memorizing a BIP39 recovery key is still no easy feat.Įnter Formosa, a powerful open-source project that generates recovery keys intended to be easier to remember. For this reason, BIP39 is credited for profoundly and positively impacting the crypto user experience. The BIP39 recovery key implementation supports keyword options that are far easier to recall than the random alphanumeric string keys of yesteryear. Cryptocurrency wallet management relies on a cryptographic recovery key-a secret word or expression with which a user protects and recovers their wallet.
