# Engeri gy'oyinza okufuna obujulizi bw'okusasula okuva mu Blink?

Nga bwe kyayogerwako mu kuddamu ekibuuzo [Okukakasa otya nti invoice y’omulabe yasasulwa? ](/luganda/blink-and-other-wallets/how-to-prove-that-a-lightning-invoice-was-paid.md)amawulire ageetaagisa okukakasa okusasula yinivoyisi ya Lightning ge gano:

1. **Lightning Invoice** eyasooka ewereddwa node y'omusasulwa
2. **Ekifaananyi ekisookerwako eky'okusasula** ekifunibwa omusasula ku kusasula okutuuse ku buwanguzi

Amawulire gano gabikkulwa mu Byafaayo Eby'okuwaanyisa ku Blink nga onyiga \`Enkola Zonna\` olwo olonde okusasula okusindikiddwa mu kibuuzo.

Koppa ebifo `Ekifaananyi / Obukakafu bw'okusasula` ne `Okusaba kw'okusasulat` nga byonna awamu bisobola okukola nga Obukakafu bw'okusasula eri omuntu yenna asobola okukakasa mu ngeri ya cryptographic.

Mu kiseera kino Preimage egabanyizibwa ku nsasula ya Lightning network yokka, naye mu bbanga ttono ejja kulagibwa ku nsasula ekoleddwa eri abakozesa Blink abalala nabo.

Mu mbeera y’okutunda ku lujegere okusasula kuweebwa mu lujjudde ku mutimbagano gwa bitcoin era ne kukakasibwa abasimi mu blockchain. Okumanya Transaction ID (txid) kifuula buli muntu okusobola okukakasa nti the enkolagana ebaddewo (omuwendo gusasuddwa ku ndagiriro ya bitcoin) mu bulooka elabika nga [mempool.space](https://mempool.space) . Okukakasa enkola ya onchain gabana endagiriro gy’ogenda ne txid era okimanye nti bino (obutafaananako lightning invoice ne preimage) birabika eri omuntu yenna asoma bitcoin blockchain.
