I totally agree with Thomas. Another thing that I think could be a BIP misdesign: BIP44 Gap Limits From the BIP: ---------- "Address gap limit is currently set to 20. If the software hits 20 unused addresses in a row, it expects there are no used addresses beyond this point and stops searching the address chain." ---------- * Does that mean, we do a transaction rescan back to the genesis block for every 20 addresses? * Or is it a prerequirement to do a wallet recovery after BIP44's to have access to a full address-indexed blockchain? Or maybe I'm missing something. </jonas>
