- How block explorer technology works? 1 answer
I wanna understand how can a user find a certain transaction he created on the blockchain without him knowing on which block it belongs ? does he have to go over all the blocks using bloom filters to find his transaction ? narrow the search to an interval of timestamps ? there must be a special mechanism ...
I searched on google but all i found were websites to find them for u, i want to understand the actual mechanism used in the bitcoin protocol?
Block Explorers seems to be storing those transactions in special databases and they use their own approach to find transactions ... My question is about how full nodes find those transactions ? do they go over the whole chain trying to find them ?
