Ramifi Protocol Prezzo

Is the UTXO index in RAM or is it a file system object?

<!-- SC_OFF --><div class="md"><p>The blockchain contains a lot of redundant information and a full node will typically build up an index from the blockchain for efficient transaction verification and generation.</p> <p>I’m wondering if that index exists in RAM or in an OS file system?</p> <p>On the one hand, swap memory should be a last resort and doesn’t scale, on the other hand, at 4GB it probably fits into RAM depending on hardware and doesn’t need to be persistent.</p> <p>What does Bitcoin Core implement? Or is it a file system object with RAM caching?</p> </div><!-- SC_ON -->   submitted by   <a href="https://www.reddit.com/user/XiPingTing"> /u/XiPingTing </a> <br/> <span><a href="https://www.reddit.com/r/Bitcoin/comments/wywsre/is_the_utxo_index_in_ram_or_is_it_a_file_system/">[link]</a></span>   <span><a href="https://www.reddit.com/r/Bitcoin/comments/wywsre/is_the_utxo_index_in_ram_or_is_it_a_file_system/">[comments]</a></span>
