Wallet and explorer now synchronized at
https://chainz.cryptoid.info/cach/Using 5.3, the bootstrap would not work, but when renaming the bootstrap's blk0001.dat to bootstrap.dat, it got imported.
I have noticed a difference in outstanding supply with the other explorer at
http://109.106.139.239:3001/, which shows a slightly higher value than what the wallet and cryptoID explorer report (cryptoID explorer outstanding supply is not based on RPC, but computed from all transactions).
