Cryptocurrency

A cryptocurrency is a digital currency that only has value dependent on those who back it. For security, cryptocurrencies rely on blockchaining: a database organized in such a way that records are kept secure through peer-to-peer networks. Each record is kept within a block, and each block holds a timestamp and link to the block before it. The first cryptocurrency was Bitcoin, implemented in 2009 by Satoshi Nakamoto.

basic block filter index best block of the index goes beyond pruned data. Please disable the index or reindex (which will download the whole blockchain agai
