BIP39

A standard that defines how mnemonic seed phrases are generated from entropy for cryptocurrency wallets.

Seed Phrase

A sequence of 12 or 24 words that serves as a master backup for a cryptocurrency wallet.

Private Key

A secret 256-bit number that allows spending cryptocurrency from an associated address.

Public Key

A cryptographic key derived from a private key, used to receive cryptocurrency.

HD Wallet

A Hierarchical Deterministic wallet that generates all keys from a single seed.

Derivation Path

A structured path like m/44'/60'/0'/0/0 that determines how keys are derived in an HD wallet.

BIP44

A standard defining multi-account hierarchy for deterministic wallets.

Entropy

Cryptographic randomness used as the source for generating keys and seed phrases.

secp256k1

An elliptic curve used by Bitcoin, Ethereum, and most major blockchains for key generation.

ed25519

An Edwards curve used by Solana and other modern blockchains, offering fast signature verification.

Checksum

An error-detection value appended to addresses and seed phrases to prevent mistakes.

Cold Storage

Storing cryptocurrency keys offline to protect against hacking.

Paper Wallet

A physical document containing printed private keys and QR codes for cold storage.

Vanity Address

A cryptocurrency address containing a custom prefix or pattern.

ECDSA

Elliptic Curve Digital Signature Algorithm — used to sign cryptocurrency transactions.

Bech32

An address encoding format used by Bitcoin SegWit, starting with bc1.

Base58Check

An encoding format with built-in error detection, used for Bitcoin legacy addresses.

SLIP-44

A registry of coin type constants used in BIP44 derivation paths.

Mnemonic

A memory aid — in crypto, refers to the human-readable seed phrase words.
