	~~===Blockchain downloader===~~
	~~For optimized initial blockchain download, Gocoin has a dedicated application called '''downloader'''.~~

	Among other optimizations, the downloader allows a user to skip verification of all the blocks up to a certain one that he defines as trusted. This can speed up the bootstrap process significantly (e.g. from days to hours).

	~~After it finishes downloading of all the blocks, it will exit automatically. In that moment the client should be started and it will keep up with all the new blocks, that will appear in the network.~~

It is possible to use Gocoin's wallet, without a need to have a running client node.
