Mnemonic mkpụrụ okwu na-akwado otu n'ime akụkụ kachasị mkpa nke cryptocurrency - ** njide onwe onye **. Taa, anyị ga-amụta etu esi emepụta mkpụrụ okwu ma jiri ya na akpa ego.
A na-akọwa ahịrịokwu mgbake site na nkọwapụta ** BIP-39 **, ụdị ụdị okwu mgbake a na-ejikarị eme ihe taa.
Eke nkebi ahịrịokwu mgbake na-amalite site na ịmepụta ** randomness **. More entropy pụtara nchebe dị elu. ** 128 bits ** nke enttropy ka a na-ewere dị ka ihe zuru ezu maka ọtụtụ ndị ọrụ.
Dabere na ogologo nke entropy mbụ, okwu mgbake ga-abụ **12 ruo 24 okwu ** ogologo.
Anyị na-amalite site na ịmepụta 128 bits nke entropy.
Anyị na-eji SHA256 mee ka entropy ahụ. Bit ole na ole mbụ nke hash a na-aghọ nchọpụta nchọpụta. Nke a na-enye anyị akara mkpịsị aka pụrụ iche maka entropy anyị.
A na-ekewa 132 bit (128 entropy + 4 checksum) n'ime iberibe nke 11 bits.
A na-atụgharị usoro 11-bit ọ bụla ka ọ bụrụ ọnụọgụ iri (0-2047). Ndepụta okwu BIP-39 nwere kpọmkwem 2048 okwu (Bekee, Spanish, Chinese, wdg).
A na-eji nọmba ndị a achọta okwu kwekọrọ na ya n'ihe ndepụta okwu.
** Nsonaazụ: ** Anyị nwere ugbu a, okwu nchekwa nke mmadụ nwere ike ịgụ 12 okwu!
N'iji okwu mgbake, obere akpa nwere ike ịmepụta igodo iji mepụta adreesị ịkwụ ụgwọ na akaụntụ obere akpa dị iche iche.
Igodo ndị e mepụtara bụ ** deterministic ** - otu ntinye ahụ na-emepụta otu mmepụta ahụ.
A na-enweta mkpụrụ nke obere akpa site na ahịrịokwu mnemonic site na iji ** Key Derivation Function (KDF) **:
Nke a na-emepụta mkpụrụ nke **64-byte (512-bit) **.
A na-ekewa mkpụrụ ahụ n'ime usoro abụọ 32-byte:
A na-eji ndị a na ** Hierarchical Deterministic (HD) Wallets ** maka isi nwa.
Na Zcash, ** ikike nlele ** ma ọ bụ ** ikike mmefu ** nwere ike inyefe onwe ya maka sub-osisi na-enweghị imebi isi mkpụrụ.
ZIP-32 na-akọwa ụkpụrụ nke isi ihe dị iche iche na-agbanwe agbanwe maka atụmatụ nzuzo nke Zcash.
Site na ** Expanded Spending Key ** anyị na-enweta:
Usoro dị iche iche na-emepụta adreesị mpụga kwesịrị ekwesị maka inye ndị na-ezipụ gafee ọdọ mmiri ndị e chebere (Sapling & Orchard).
Zcash na-akwadokwa ** adreesị dị n'ime ** maka ọrụ obere akpa dịka Auto-Shielding.
