Is iCloud storage secure enough for Bitcoin Core?

[m1ewi5]

I don't have enough hard disk space for full node. Running OSX 10.13. I created ~/Library/MobileDocuments/Bitcoin as an attempt to run a full node, using both iCloud and hard disk . Bitcoin Core program seems to be running OK, but is this a secure enough storage scheme to maintain Bitcoin core?

Generally, to be 100% safe, I wouldn't recommend anyone using cloud storage at all; be it the chainstate or the block files. It would probably be somewhat fine if you don't expose your wallet.dat to any cloud storage.

Are you using Core for personal use? If so, you might want to consider pruning the blockchain by creating bitcoin.conf in the data directory and inserting this:

Code:

prune=550

.

You can shift the blockchain back into the HDD once you've done this.

I'm not familiar with iCloud, but if this means you store it on the cloud and on your hard drive, you still have the problem of not enough disk space.
As for your iCloud: are you sure you can fit the complete blockchain in there?

Bitcoin Core program seems to be running OK, but is this a secure enough storage scheme to maintain Bitcoin core?

That means you're downloading 170 GB, uploading it too, and when Bitcoin Core needs to access it, it has to come through your internet connection once again? This sounds like a terrible way to use Bitcoin Core.
My advice, pick one:
1. do what ranochigo says (prune it)
2. buy a bigger hard drive
3. or use something like Electrum instead of Bitcoin Core.
