This post is for users who are facing trouble syncing their wallets. Before we get in to the troubleshooting guide we need to first figure out if your wallet is actually syncing or it is really stuck? Hover over the progress bar or click on the refresh icon and it will show the status on processed blocks and last received blocks. It shows something like this: Catching up Downloaded blocks of transaction history.

Last received block was generated 6 days ago. If it shows some progress the it is syncing and be patient while it does. If that is your case then here are few ways to troubleshoot an out of sync qt wallet. Here are some common reasons: Broadband and Firewall issues No active connection to the coin network Your blockchain data might be corrupt and Your wallet could be old and might be on the wrong chain. Now before you make any changes the first thing we recommend you to do is take a wallet backup.

Internet connection and Firewall issues First check if your PC has a healthy network connection. If nothing is wrong with your Internet then check whether if your Firewall or Antivirus is blocking the wallet from running. As we said your wallet needs to connect with other nodes to download the blockchain. So ensure that your firewall or network is not blocking your wallets incoming and outgoing connections. Hover on the vertical bars and check the total number of active connection to the network.

If the connection is strong then proceed to the next step. If there are zero active connections or if it has less than 4 or 5 active connections then you need to add nodes to your wallet. Once done restart the wallet. Now the total number of active connections should be more than before and your wallet should start syncing.

Corrupted blockchain The best way to get your wallet files corrupt is by forcing your wallet to shutdown while its running. There are also many other instances in which your wallet or the downloaded blockchain can get corrupt. In such case what you need to do is head to the wallet core folder location and except wallet. But before you do this close your wallet and again remember to backup your wallet. Once the files are removed restart the wallet and it should start synchronizing with the network.

Note the dissonance with the "bigger block" movement in the Bitcoin community? Nodes behind NAT. Full nodes need to serve the same bandwitdh as they request from the network. When this doesn't happen we get what the Torrent community calls "leeches". The "fast" algorithm requires the entire chain structure to be downloaded , per block, before processing the block.

Let's take a quick look at each of these factors. Finding Peers There's very little we can do about this issue. Discovering initial peers is an inherent difficulty in all P2P networks. There have been other fully decentralized P2P systems and most were also notoriously slow when unable to bootstrap initial connections to enough peers on the network.

There have been decentralized anonymous systems like Freenet which still exists BTW , but which are also very slow because they depend on nodes talking directly to each other to exchange information on a large scale. There isn't one fast centralized node aiding the network in a truly P2P system. Many nodes are also run in slow and limited internet connections. When you connect to a slow node, it will drag the entire sync operation slower with it until your node detects a lagging connection and tries a different peer.

There is nothing you can do to avoid connecting to slow nodes a first time. When you find a very slow or incorrectly running node you can blacklist it or quarantine it in your local peer list. But it's impossible to know it's a slow node before connecting to it at least once. Spam Spam is a problem in every Internet related crowd-driven technology.

Be it a Telegram chat, IRC, forums or even cryptocurrencies, spam is everywhere. But every spam operation must be profitable, otherwise there'd be no incentive for it. What's the incentive for cryptocurrency blockchain spamming? The answer is usually to promote a rival cryptocurrency. We've seen spam attacks against Bitcoin, Ethereum and against every other mineable and top ranked currency. The spam attacks usually consist of submitting millions of tiny transactions which clog up the network and fill the mempool of unconfirmed transactions.

There may be other more sophisticated attacks, but the simplest one is usually what slows the whole network down. When this kind of attack is perpetrated by actors with high bandwidth and lots of cash and resources, they are almost impossible to deflect. But even so, Bitcoin and Ethereum have held up against most the bombardments received, especially throughout when big money began to fear the spread of cryptocurrencies. Block Size If there's one good argument against increasing block size in the Bitcoin blockchain, then Ethereum must be it.

Ethereum blocks can be of any arbitrary size, limited only by the GAS limit itself. GAS is a measure of computational resources spent in processing Ethereum transactions including smart contract interaction. A bigger and more complex contract requires more GAS than a small and simple one.

GAS is the computation currency in the "world computer" composed of all Ethereum nodes. When a contract is very large and complex, it will require large amounts of GAS, which is itself traded for Ethereum. The amount of GAS limits the amount of contracts and transactions contained in a block.

Therefore GAS indirectly limits the physical size of Ethereum blocks. Therefore, a immense part of the Internet sits behind NAT routers. This is how most internet providers are able to offer access to household computers. The provider itself has a small range of IPs it acquires from a backbone operator, and these IPs are distributed to its customers. One small internet provider IP can serve thousands of non-routable private IPs.

Imagine if there were no filtering, everyone's files and insecure configurations would be open to the world. This has, in fact, already been exploited by hackers before. For example, when worldwide printers started spitting out funny drawings, because hackers had found thousands of open and shared printers on unfiltered networks! So NAT is there to help us. But there's a catch. NAT is terrible for P2P networks.

When this does not happen, the uploaders quickly run out of bandwidth and the P2P network slows down. Most Ethereum full nodes sit behind heavily filtered NAT firewalls and there is very little the core devs can do about this. The Fast Algorithm Finally, there's the new fast syncing algorithm. We won't go into the details of how this works, but what you must know is that this algorithm requires the full chain structure to be downloaded before each block can be committed to the local blockchain database.

As we've mentioned, some blocks are gigantic and take days to fully download the whole chain structure.
