Entropy
cryptography
security
Entropy is the randomness used to generate secure wallet seeds, private keys, and nonces in cryptographic systems.
1
concept
Entropy quantifies unpredictability. Wallets need high-quality entropy to create seeds and keys that cannot be feasibly guessed, and poor entropy can make otherwise strong cryptography fail.
2
best-practices
Avoid homebrew key generation unless you fully understand the process. Prefer devices and software that document their entropy sources, use CSPRNGs correctly, and support deterministic signing to reduce nonce risk.
