They individually run their own Bitcoin Core full nodes, and each of those full nodes separately follows the exact same rules to decide which block chain is valid. There's no voting or other corruptible process involved: there's just individual software following identical rules—"math"—to evaluate identical blocks and coming to identical conclusions about which block chain is valid. This shared agreement called consensus allows people like you to only accept valid bitcoins, enforcing Bitcoin's rules against even the most powerful miners.

Just for kicks he thought he would try the same file on a bog standard PC, opened it in Illustrator and it was completely normal. The opposite result is probably true for some operations. Also note, I have observed that exiting and restarting Bitcoin Core during initial sync seems to speed it up a bit for a while once it connects to nodes again. Referencing again personal experience, syncing on Windows 10 bit seems to be orders of magnitude faster than syncing on Linux on the same hardware - even if Windows is running in Gnome-Boxes, it easily churns through blocks per second during the initial stages of download.
If you are in serious trouble waiting to sync Bitcoin Core a full node client and you do not need the additional features that Bitcoin Core provides then, you may consider trying Electrum not a full node client which does not need to do the initial sync. On Fedora 27, getting Electrum is as simple as sudo dnf install electrum. Here's a quick fix to alleviate your issues.
Manually specify peer IPs to console. You can get node IPs from a public node directory, such as Bitnodes.
Amazon, Google, etc. It should increase your speed a bit since those nodes will assist you with peer discovery. Use the latest release 0. I read the very helpful answer of Willtech and derived the following command:. This resulted in a sync time of roughly 2 weeks on that PC. Very long indeed but much better than having to buy new hardware For some reason some nodes does not give you any blocks when you are connected to them.
If a node does not give you any data just ban it by right clicking and selecting "Ban for 1 hour" do this until you are connected to a node that actually sends you blocks. Normally just waiting will eventually resolve this issue but banning nodes until you get connected to some fast ones is a much faster way.

I'm on 0. I receive a new block about every 20 seconds. Approx 2 incoming, 4 outgoing connections. I use it on Windows 8. I have 8 outgoing connections now i needed to delete one blockchain file because a seperate issue after i have asked this question.
Currently it takes 3 years to download everything which is nonsense. It is probably not the actual downloading of blocks that is making it slow. From personal experience on a 2. Most of the slow seemed to be validating blocks. It was certainly nowhere near as slow initially, so I suspect a BIP has activated somewhere along the blockchain that causes validation to execute slowly after that. I did notice it seemed faster for a while if I safely exited and let Bitcoin Core shut down nicely before starting it up again.
Hi Willtech, thank you. It turned out that Bitcoin Core does not work very well with network drive. I have mapped the data since with iscsi and this worked fine.
Still all the syncing is slow in general by design which is bad, but there seems to be nothing to get around it. That would do it. If my answer below has helped you I would appreciate it if you would mark it as accepted so that the question does not remain "unanswered". Active Oldest Votes. Bitcoin Core sync very slow Bitcoin Core is capable of full sync in a relatively short period of time depending mainly on the hardware.
Performance of initial sync Performance of initial sync largely comes down to the individual performance of your computer, provided your internet is fine. Adjusting parameters There are some parameters that you can look at and consider depending on your system. Some things to consider that could make a difference: I am presuming here that you are running bitcoin-qt which is the GUI version and not bitcoind.
