# BIP-39 BIP-39 specifies mnemonic sentences for generating deterministic wallet seeds. It standardizes the conversion between entropy, a checksum, a word list, and a seed used by compatible hierarchical deterministic wallets. ## Notebook evidence The redacted mnemonic sequences on [[Scanned_20260730-2016]], PDF pages 23 and 34–36, are analyzed as BIP-39-style wallet recovery material. The exact words must remain only in the redacted source reconstruction and must never be tested. ## Boundary A visible word count or wallet application does not prove that every recorded phrase used BIP-39, that phrases were shared across apps, or that any wallet remains active. Determine lineage from public addresses and application records, not from importing secrets. ## Source - [[Scanned_20260730-2016]], PDF pages 23 and 34–36. - [BIP-39 specification](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki).
