Hi, There any bootstrap for GAP?
Hey, yes.
You can find it here, the first line :
Release & BootstrapAnd to quote M. Higgins :
'You just need to copy bootstrap.dat into your (empty apart from gapcoin.conf) datadir folder, the client will detect it and import it - creates the blocks and chainstate files.'

This one is a little old now, but it's better than nothing (:
