You can download the CPUchain blockchain backup file ( not bootstrap ) from our servers in case of slow sync speed.
Download: http://cpuchain.org/cpuchain-db-337094.tar.gz
$ wget http://cpuchain.org/cpuchain-db-337094.tar.gz && tar xvf cpuchain-db-337094.tar.gz
This will download and extract the synced blockchain files on your home location, ~/.cpuchain
Please update backup file.
