ZecHub maa saa asɛmmisa yi sɔree bere a ɔde shielded DASH kaa ho sɛ wiki ntoboa kwan akyi: so Zcash-style viewing keys, anaa FROST threshold signatures, betumi akyerɛ ase akɔ Dash?
Nhwehwɛmu no san hyehyɛɛ no bio. Hwɛ safoa nyɛ asɛmmisa a wɔabue — Dash shipped the Zcash Orchard a wɔabɔ ho ban ɔtare akɔ ne Evolution nkɔnsɔnkɔnsɔn no mu, na Orchard's safoa nhyehyɛe no bi ne safe a wɔbɛhwɛ denam adansi so. Dash ankasa deɛ ɔkwan a wɔfa so yɛ adwuma de wɔn si hɔ ma akontaabufoɔ a wɔbɛda no adi ne Akwantuo Mmara a wɔdi so. Wɔde saa fã no di dwuma, ɛnyɛ nsusuwii hunu.
FROST ne baabi a nokware gap no te. Dash dedaw tu mmirika BLS threshold signatures fa Masternode Quorums a Wɔtena Ase Bere Tenten, nanso wɔn no som network-level adwene a ɛwɔ hɔ — ChainLocks ne InstantSend. ZIP 312 na ɛwɔ hɔ de n’ani si biribi soronko so: threshold spend authorization wɔ shielded account biako a ankorankoro keyholders kuw ketewaa bi kura so. Ɛnyɛ nea wotumi sesa abien no. Na esiane sɛ ZIP 312 da so ara yɛ Draft nti, reference implementation biara nni chain to port biara so, enti eyi bɛyɛ adwuma foforo a ɔfã biara a ɛkyekyee no.
Nsɛm abien a esisii wɔ shielded-pool mu sii wɔ adapɛn kakraa bi mu wɔ afe 2026 mfinimfini.
Zcash tu fii Orchard. Nhwehwɛmufo Taylor Hornby daa ɔmansin mu mmerɛwyɛ bi adi wɔ Orchard a wobetumi de adi dwuma de ama nneɛma a wɔde ma no ayɛ kɛse a wontumi nhu. Zcash buae denam Ironwood (NU6.3) a ɔde yɛɛ adwuma wɔ 28 July 2026, de ɔtare foforo a wɔabɔ ho ban a ɛwɔ turnstile migration mechanism bae.
Dash tu kɔɔ Orchard. Dash de nhyehyɛe no too gua wɔ 19 Ɔpɛpɔn 2026 — "Yɛhwɛ kwan sɛ yebetumi ahyɛ shielded transfers ase nnansa yi ara, sɛnea ɛte no, yɛretwɛn ahobammɔ ho akontaabu ne mmara mu nhwehwɛmu foforo." Dash's ɔkwan a wɔfa so yɛ adwuma kyerɛwtohɔ Shielded Balances sɛ wowiee wɔ July 2026 ne Dash Platform v4.0, na Dash tintimii "Nkitahodi a wɔabɔ ho ban no wɔ Dash Evolution mainnet no so" wɔ 4 Ɔbɛnem 2026.
A note on ordering. Ebinom coverage de Dash mainnet activation no too 17 July 2026, a ɛde bɛto Ironwood. Ɛte sɛ nea saa da no fi nsɛm ho amanneɛbɔfo amanneɛbɔ a ɛfa dawurubɔ no ho sen sɛ ɛbɛkɔ so ayɛ adwuma. Wɔ Dash ankasa fibea ahorow no afã no wiee wɔ July mu na wɔde too gua live wɔ 4 August — Ironwood. Nkɔnsɔnkɔnsɔn abien no twaa akwan wɔ adapɛn kakraa bi mu; sɛnea wɔahyehyɛ no pɛpɛɛpɛ no gyina ade titiriw a wɔkan so, na saa krataa tiawa yi nkyerɛ sɛ ɛyɛ bi.
Nea ɛho hia titiriw no, Dash annye mmoawa no fii awo mu. Wɔn dawurubɔ no da adi pefee: "yɛde Orchard nkyerɛase no dii dwuma a na wonni inflation bug a wonim. Na nkyerɛase a atwam no kura mfomso bi a wobetumi de adi dwuma de ahyɛ Zcash's supply no mu ma a wontumi nhu."
Enti Dash seesei tu mmirika patched fork a cryptography Zcash ankasa atu afi wɔ base layer, bere a Zcash's awo ntoatoaso a edi hɔ pool (Ironwood) ne awo ntoatoaso a edi hɔ spend-authorization nhyehyɛe (FROST) yɛ sɛnea ɛte biara foforo te ase na ɛda so ara Draft.
Dash ɔtare a wɔabɔ ho ban no yɛ Orchard, a wɔasi wɔ Halo 2 zk-SNARKs so a enhia nhyehyɛe biara a wotumi de ho to so. Orchard's safoa nhyehyɛe no de Full Viewing Keys ne Incoming Viewing Keys aka ho bere nyinaa sɛ ne nhyehyɛe no fã sen sɛ ɛbɛyɛ nea wɔde ka ho — enti tumi no bae ne koodu no, ɛnyɛ sɛ hyɛn gyinabea a na ɛsɛ sɛ nkɔnsɔnkɔnsɔn biara di nkitaho.
Dash kwankyerɛ no ka adwene no tẽẽ:
"Nea ɛnte sɛ kokoam nsɛm nhyehyɛe a ɛyɛ ahyɛde a ahyia exchange delistings ne mmara mu akasakasa no, Shielded Balances boa paw a wɔda no adi denam view keys so — ɛma wɔn a wɔde di dwuma ne nnwuma ma wɔne akontaabufo kyɛ asɛm no ho nsɛm anaasɛ wodi Akwantu Mmara ahwehwɛde ahorow so bere a ɛho hia, a wɔrensɛe kokoamsɛm a wɔde bedi dwuma da biara da."
Nneɛma abien a wɔahyɛ no nsow a ɛfata sɛ wɔkyerɛw to hɔ:
Dash de hwɛ safoa resi hɔ atwa ade a wɔde di dwuma a ɛyɛ kɔnkrit kɛse ho ahyia sen sɛnea Zcash's ankasa nnwinnade adu ho.

Dash de view keys remena sɛ compliance feature a wɔato din use cases, wɔ chain a ɛsan nso de bɛyɛ second baako deterministic settlement ne bɛyɛ aduonu mmienu wallet sync ma wɔ n’ankasa dawurubɔ biara mu.
Adeɛ a wɔabue no yɛ compatibility drift, ɛnyɛ capability.

Zcash de di dwuma ZIP 32, Shielded Hierarchical Deterministic Sikakorabea, a ɛwɔ gyinabea Final. Sɛ́ anka wɔde safe a wɔabɔ ho ban bɛhyɛ BIP 32 dua biako mu no, ZIP 32 ma ɔtare biara a wɔabɔ ho ban no n’ankasa safe titiriw ne n’ankasa kwan:

Dash safoa atenaeɛ no kura biribi a Zcash's nni: BLS domain a ɛyɛ soronko. Masternode operator safoa, abatoɔ safoa ne quorum safoa a LLMQs de di dwuma yɛ BLS safoa, ɛnyɛ Schnorr-abusua safoa, na ɛte BIP 32 dua a yɛaka ho asɛm wɔ atifi hɔ no akyi koraa.
