Normally the Dogecoin Core client will download the transaction and network information, called the blockchain, from network by syncing with the other clients. This can be a process that can take multiple days as the Dogecoin block chain has grown to more than 3 gigabytes, and is growing almost half a gigabyte every month. Luckily there is a safe and fast way to speed up this process. We’ll show you how to bootstrap your blockchain to bring your client up to speed in just a few simple steps.
Launch the Dogecoin Core client once before continuing the process and then exit the Dogecoin Core software. Be sure not to have an actively used wallet in use. Now we are going to copy the download of the blockchain to the Dogecoin Core data directory. You should run the client software at least once so it can generate the data directory. Copy the downloaded bootstrap.dat file into the Dogecoin data folder.
Wait until the import finishes. The client will download the last days not covered by the import. Congratulations you have successfully imported the blockchain!
### Is this safe?
Yes, the above method is safe. The download contains only raw block chain data and the client verifies this on import. Do not download the blockchain from unofficial sources, especially if they provide `*.rev` and `*.sst` files. These files are not verified and can contain malicious edits.
