user37839: I have a machine with ~40GB in storage. The Bitcoin block chain is ~75GB in size, is there any chance to run bitcoind in my system? I mean, can I somehow skip downloading some part of the block chain?
Thanks in advance for any answers.

user208: You cannot skip downloading the blockchain, but you can skip storing it.
If you run Bitcoin Core with the -prune=N or put prune=N in the bitcoin.conf file, only at most N megabytes worth of blocks will be stored on disk. N has to be at least 550 currently.
Pruning does not reduce the validation or security at all, but does prevent your node from serving historical blocks to other peers.
