It's taking far too long for ethereum node to sync. I've been running my computer for at least half a day, internet speed is definitely not the issue. I'm at block 2,000,000 of 3,866,000 and the last 150,000 blocks have probably taken at least 6 hours. I've tried to find other users commenting on similar issues and the only thing I could find was reference to the system clock of the computer. I'm on a mac so I've manually edited it but it doesn't seem to do anything so it's automatically synced with time.apple.com.

System information

Version: `0.8.10`
OS & Version: osx
Node type: `eth/geth 1.6.5 (go)`

It gets to the point where it downloads more blocks before it stalls and I have to usually force quit the app and restart it to get it going to download more blocks. My hard drive has more than enough space so don't think this is the issue. I've tried to run it all on it's own so don't think it is a computer resource issue.

i'm seeing the same issue. i left my computer on for about 18 hours and still under 2.5 million blocks. i'm just recently learning about how all this works, so please don't mind my question if there's an obvious answer, but is there a reason wallet nodes on the network need the entire chain, instead of say, the most recent million? and then miner nodes could include the full chain for integrity

Seeing a similar issue, blockchain takes a long time, gets nearly to 100%, then starts the sync over again. I tried deleting the l%APPDATA\Roaming\Ethereum\geth\chaindata directory and restarting. That made the sync download run faster, I assume because it was doing a --fast sync, but it still fails to complete. I am using a Windows 10 PC, running 0.8.8 so I will update the build and try again just in case that's contributing.

I've been trying to sync for more than 3 days now, have downloaded close to 50GB of chaindata and I've another 1.5Million blocks left to sync.

I am also new to this whole lot and don't want to end up loosing cash!
In my hyped-up hurry to buy ETH I rushed into installing Ethereum Wallet app, copied the first legit looking address and used Changelly to change BTC to ETH and sent it to that address (my main account in the Ethereum wallet).

5 Days later still no sign of the ETH in my wallet. I'm hoping it is due to the ever-lasting sync ..?
I feel like my coins are being held at ransom. What if it NEVER finishes syncing. :(

it seems that these tech-smart people have not made etherium participation user friendly AT ALL! Bitcoin is so uncomplicated! My Ether also 'lost' in thin air due to needing to 'sync'. Sync what for goodness sake?! I'm not a miner. 100gb sync data down already, in a perpetual sync. SO FRUSTRATING. I can see my ether on https://etherchain.org but i cant do a thing with it at all. Cant get it into ANY wallet whatsoever.

Yep. Same issue here. I've had my computer running non-stop, doing nothing but syncing the ethereum wallet and I'm still more than 1,5 million blocks away from done. And in the last two days or so progress has really come a near standstill. In the last 10 hours the wallet synced only about 15,000 blocks. At this pace it will literally never fully sync...

I've downloaded JAXX. It's a lightweight multi-coin wallet, but I'm using it to receive and store Ether. For now. Until I find a way of syncing the full node Ethereum Wallet.

@alwayslookright I just started using Exodus. Before that, I was keeping it all in coinbase, which i don't advise because of the frequency of their outages lately. It's also more secure since you hold your private keys instead of a third party

Downloaded so far 50.6 GB

So, in 24 hours 5,051 blocks were downloaded, and since 1,485,049 left, it will take me 294 days :) nice... plus, by that time couple of millions extra blocks will be mined :)

Are these recommendations good ones?
https://ethereum.stackexchange.com/questions/603/help-with-very-slow-mist-sync

They say to start from very beginning and start geth with --fast --cache=1024 params and process will go much faster. Anybody knows about this?

Or use MyEtherWallet :-)

top man for sharing @ddon .....

@tomtom87 . Just use geth on command line as per above and it works fine.

  1. rm -rf ~/Libary/Ethereum/geth/chaindata ( or whereever chaindata has been stored on your machine. ) to clear out the old sync data. Otherwise it stays in slow mode.

  2. geth --fast --cache=1024

You'll see it sync pretty quick.

I deleted my chaindata and am trying to get my wallet to fast sync. I am using a linux soft link to save my chaindata on a different hard drive. I am usingethereum wallet --fast --cache=1024 to run the wallet. Is that effective, or do I have to run geth first with the command?

I am having an issue where my node is perpetually 50-100 blocks or so behind. I am not seeing any peers listed in the wallet GUI. Any ideas how to fix this?

It also seems that if I leave the wallet in the loading screen (ie do not click 'launch application' to run the GUI) it syncs faster. Has anyone else noticed this?

Tnx Hawaii18K.. Have SSD with mgmt on it so that goes automatically. What did the trick was geht with light opt on. synced in 3 hrs (about 70Gb).. shitty prg who does load al the chain (like BCoin does w/160Gb)... but Bcoin loads in 3 mns and ethwall needs f#cking 2 hrs to sync. Think i shapeshift it to lcoin. have a nice wcnd!

All of this is assuming you have geth in place etc and usually -v 1.7.2 or above.

ok it is final guys! This is the solution:

  1. $ cd ~/Libary/Ethereum/geth/
  2. $ mv chaindata chaindata_backup
  3. $ mkdir chaindata
  4. $ geth --fast --cache=1024
  5. open ethereum wallet but DO NOT click on Launch Application.
  6. Wait and if it all works fine (after 100% sync) then, remove the chaindata_backup file by doing $ ~/Libary/Ethereum/geth/chaindata_backup

Guys, use Ethereum CLI client from https://github.com/ethereum/go-ethereum.
I use geth --datadir "<Your dir with geth and keystore dir inside>" --syncmode "fast" --cache 2048 --maxpeers 50
It works for me!
Before using backup Your geth/chaindata dir and make new empty geth/chaindata dir.

the geth sync kept failing every 10 to 15 minutes so in windows i created a sync.cmd file with the following and that took care of it.

C:
cd "C:\Users\Dan\AppData\Roaming\Ethereum Wallet\binaries\Geth\unpacked"

:loop

%@Try%

call "geth.exe" --fast --cache=512 --datadir="D:\Ethereum-Wallet-win32-0-9-3"

timeout 2

Have been at it for months (not 24/7, probably an average of 10-12 hours daily), I remember updating the client at least 3 times already during this period of time. I only need like 150k blocks now, they download at around 1 block per second, sometimes faster sometimes slower.

Hello everyone, using pc with at least 8GB RAM + 8GB swap with ssd 250 GB drive solve this problem for me.
In the other side I tried to sync at win, linux and mac and had the same result: it syncing one block slower then the new one created.

I have sent ETH to my Ethereum Mist wallet...however, my client won't finish the sync anymore it seems...65 blocks left and there is sort of stalls... I wanted to use that ETH to buy some altcoins, but of course I can't get to see a balance. Adding a sole proprietor contract isn't working either...

Can I use the keystore of the Ethereum Mist wallet to access this wallet via another platform? I am pretty new to all this cryptocoin stuff, but am fairly savvy with cryptography and security in general, so you can go technical on me :-)

@orbatec just import your key on www.myetherwallet.com and you should be able to do everything from there.

At least I prefer to keep my wallet and keys on my own system....
In fact I also have major trouble. About 10 other wallets run nice except Ethereum. Today I have not more than 2 peers. sucks...
And yes, I've read everything about "ISP limit swarm connections". But I do not have that troubles with others and able to connect to hundreds of peers using Bittorrent for example.
And yes - my system clock is fine (NTP from Firewall NTP server)

The whole geth --fast --cache=2048 didn't do diddly... So I ended up installing Parity and importing my geth keystore from Ethereum Wallet. Low and behold, my ETH is finally showing up! And it took Parity only about 2h to find my block.... On the downside I left my computer on all night and now I have some serious wear on the fans as it has been huffing and puffing non-stop with processor usage up to 171% ... I am fairly new to blockchain and cryptocoins, but this is a huge problem imho. I would expect that once you are in sync it should not continue to consume all of your resources, but it does...I actually find it quite useless this way...

Using myetherwallet -I assume- has the benefit that you are not doing the synchronization yourself: it is done by the platform...And yes, I too like to keep my wallet private, but the way it is now, it really isn't usable...

I had no luck at all syncing with the light-client. After switched off it works way better.
also forwarded 30303 from firewall to desktop. Seeing 2 incoming connections which seem not change a lot

I have no other idea than there must be attacks to the network. Had not more than 1 up to 3 peers for WEEKS but gone up to about 20 peers a few day ago.
It is still very slow but continued importing!
With cache of 2048 it is no problem at all using HD OR SSD since I/O and disc-access is very low as well as network traffic.
When monitoring this I found "Microsoft photos" periodically takes a multiple of geth resources and bursting my drives hot. Removed that stuff to free shitloads of resources.

my wallet downloading and synchronizing get lots of time. there is any option for reduce the time for downloading blockchain?

*this is my code *

`public class xyz {
private static WalletAppKit kit;
private static NetworkParameters params = TestNet3Params.get();
private File file;

public xyz(File file) throws BlockStoreException {
    this.file = file;
}

public static void refresh() throws ExecutionException, InterruptedException {
}

public void initialdownload(String btcpri, Context context) {
    ECKey key;
    BigInteger privKey = Base58.decodeToBigInteger(btcpri);
    key = ECKey.fromPrivate(privKey);
    setSDKThread();
    BriefLogFormatter.init();

    kit = new WalletAppKit(params, file, "bitcoin_wallet") {
        @Override
        protected void onSetupCompleted() {
            wallet().importKey(key);
            wallet().allowSpendingUnconfirmedTransactions();
            setupWalletListeners(wallet());
        }
    };
    kit.setDownloadListener(new DownloadProgressTracker() {

        }

        @Override

        }
    });
    kit.setBlockingStartup(false);
    kit.startAsync();

            Threading.USER_THREAD = handler::post;
        }
    });
}

    wallet.addCoinsReceivedEventListener((wallet1, tx, prevBalance, newBalance) -> {
