Zcash Sikakorabea Syncing
TL;DR
- Esiane sɛ shielded Zcash transactions sie wɔn nsɛm nti, server ntumi nhwehwɛ wallet’s balance kɛkɛ ɔkwan a ebetumi ama transparent coins te sɛ Bitcoin anaa Ethereum.
- Lightwallets twe “compact blocks” nketewa fi server titiriw bi so (lightwalletd) na wɔn ankasa de wɔn private keys decrypt data a ɛfa ho no.
- Saa blocks no a wobɛpopa na woadi ho dwuma no gye bere, enti sika kotoku de akwan a wɔfa so yɛ synch ntɛmntɛm di dwuma na ama wode wo sika adi dwuma ntɛm.
- Akwan a ɛda nsow: Warp Sync (YWallet), Spend-before-sync (Zcash Mobile Wallet SDK V2), Blaze Sync (Zecwallet), ne DAGSync a wɔahyɛ ho nyansa no.
- Mpɛn pii no, saa akwan yi de memory anaa tumi a wɔde di dwuma foforo di gua de nya synchronization ntɛmntɛm.

Warp sync yɛ YWallet ade a ɛhuruw anammɔn a ɛwɔ ntam a ɛfa decrypting ne dwumadie a ɛfa compact block biara ho, na ɛhuruw tẽẽ kɔ nea ɛtwa toɔ no so.
