To speed up syncing of the I/O Coin blockchain from several days to a couple of minutes you can use the bootstrap files. The bootstrap is regularly updated by the team over on GitHub. Follow below steps to use the bootstrap files. This guide assumes you have already successfully installed the wallet, if you haven't done so yet you can find the installation guide here.
Go to the Wallet Releases page on the I/O Coin GitHub, download the bootstrap zipfile and unzip the files.
If you have never opened your wallet before, open the wallet until it is fully loaded (the pulsing logo will disappear) and then close it again. When asked whether to leave the daemon running, click No.
Navigate to your I/O Coin wallet folder and replace the 'txleveldb' folder and 'blk0001.dat' with those from the bootstrap file.
Now you can open your wallet again. Starting up the wallet will take a little bit longer than usual because the wallet is loading the files.
It is best practice to always make a back-up of your wallet folder before making any changes to it!
Below video briefly shows the above steps as well.
