Occasionally the format of those files changes, but the new Bitcoin Core version will include code that automatically upgrades the files to the new format so no manual intervention is required. Sometimes upgrade of the blockchain data files from very old versions to the new versions is not supported. In those cases it may be necessary to redownload the blockchain. Check the release notes of the new version if you are planning to upgrade from a very old version. Sometimes downgrade is not possible because of changes to the data files.
Again, check the release notes for the new version if you are planning to downgrade. When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions.
You can use the testing instructions below to confirm your server-based node accepts inbound connections. Home connections are usually filtered by a router or modem.
You may also need to configure your firewall to allow inbound connections to port Please see the following subsections for details. The BitNodes project provides an online tool to let you test whether your node accepts inbound connections.
Before using BitNodes, you must first ensure that your node is fully synced with the block chain. The tool will attempt to guess your IP address—if the address is wrong or blank , you will need to enter your address manually. After you press Check Node, the tool will inform you whether your port is open green box or not open red box. If you get the red box, please read the enabling connections subsection.
For confirmation that you accept inbound connections, you can use Bitcoin Core. If your node has been online for at least 30 minutes, it should normally have inbound connections. If want to check your peer info using Bitcoin Core, choose the appropriate instructions below:. If you hover over the signal strength icon, it will tell you how many connections you have.
