This means that your wallet will still download the whole blockchain and verify it, but will save to HDD only the data it decides that you'll need for your wallet and transactions. (I am not sure it's an accurate definition, but it should give you an image) - as opposite to saving it all.
If the prune mode is enabled, only the last x blocks are kept in your HDD, so the size of data doesn't exceed a certain amount.
Assume that prune=550
Bitcoin core downloads the first block, second block, third block and ....
Once the size of data reaches 550 MB, the first block is removed from your HDD.
Hi NeuroticFish'!
Thank you for help and explanation of how prune works!
Seems like everything working good
...But: Its been exactly 20 days when I start to download whole blocjchain (its not downloading 24/7 but minimum 15 hours everyday and 24/7 during weekends) and Iam only on 44,44 % its goes very slow.
I think its beacuse of old hdd and small amount of ram (only 4 gb)?
Can I simply copy wallet.dat from old pc to my iMac with SSD and 12 gb of ram to make the process faster?
Or its not that easy?
Thanx in advance
