+## Requirements
 
 - RPC access to a bitcoin full node
     - unpruned because we need the prevouts for every transaction in the block with a taproot output
     - Note: Indexing will take longer if the rpc calls take longer;
       You might also want to allow more rpc workers on your node to speed things up.
 - Processing a block takes ~100ms-300ms
 - Disk space (~10Gb)
