How Long Does Bitcoin Core Take to Sync?
The time required to sync can differ extremely from a few hours to several days.
To provide a good estimate, we need to look at the single components of Bitcoin Core.
In the following article, we’ll discuss each element in more detail so you know what syncing times you can expect for your full node.
Bitcoin Core is a full node client that validates transactions on the blockchain. It can further provide users wallet functionalities to interact with the blockchain directly.
The Bitcoin Core wallet lets users view all their addresses and balances so you can use your bitcoins together with the blockchain data in one tool.
To ensure that your node has the latest data, it must be constantly downloaded and verify all transactions happening on the blockchain. This process is called “syncing”.
Not only that, but for the Bitcoin Core initial synchronization, the client has to further download all past transactions since the inception of Bitcoin. This needs an exorbitant amount of storage and internet speed.
Why You Should Know How Long the Blockchain Can Synchronize?
It’s helpful to know how long it takes to sync for different reasons.
You can determine if the data you try to sync is too large to transfer in a timely manner, especially if you have to download and process the initial sync of the whole blockchain.
Understanding the process can help to plan your resources and workflow more efficiently, allowing you to set realistic expectations. It can further reduce frustration with waiting for the completion of file transfers.
If you are aware of the syncing times, you can even troubleshoot any issues that may arise during the syncing process. Being knowledgeable is always key to working with digital data.
Bitcoin Core Synchronization
Synchronization means downloading and verifying all transaction history on the blockchain.
Synchronization is an essential part of the Bitcoin Core to manage your wallet because it ensures that the records are up-to-date and accurate.
You can access your wallet balance backed with the current and most accurate data because of the direct access to the blockchain. This can give you the confidence that your transactions are securely processed.
If you keep your wallet synchronized, you can make sure that your funds are secure, and it minimizes the possibility of risks. The fully synced Bitcoin Core can take time to achieve this state. This depends on different factors that affect this time.
Once the process is completed, you have the most up-to-date data in your Bitcoin node.
Bitcoin Core Requirements for Syncing Time
Syncing time is affected by different factors like the speed of your internet connection, the amount of data being transferred or the device and its specifications you use.
Slow internet connection can be a crucial factor, especially for the initial download, which can accumulate several hundreds GB of data.
The more powerful your hardware, the faster the syncing is. The speed of your processor defines the time it needs to complete tasks like syncing. Let’s look at some of these factors in more detail.
Blockchain Size – Amount of Transactions Stored
To make the blockchain the incorruptible digital ledger in its secure and public way, it needs to store every transaction and information associated with it.
This allows all participants to verify the data stored in it.
The blockchain stores this data permanently, too. This way, we can trace every Bitcoin back to its origin where it was mined.
Each block contains a cryptographic hash of the previous block, so the connection between current and all past transactions allows for this traceability. The amount of data is thus immense.
Currently, as of December 2022, the entire blockchain size amounts to about 445GB. Together with the Bitcoin Core client itself, it is required to have about 500GB of disk space available on your device.
You should further calculate with 5-10GB per month on additional data. This requires not only an appropriate internet connection but also storage.
Your computer hardware refers to the components that your computer comprises.
These include different parts like your processor, memory, storage drive and graphics card.
Depending on your operating system, the specifications can differ. The use case of your device specifies the hardware requirements.
If you use your computer solely for the Bitcoin full node, you will need less computational power than if you would use it simultaneously for daily tasks. The CPU should be able to handle all tasks for the Bitcoin core.
The RAM should be sufficient for the tasks that the software will run. 2 GB of RAM are recommended. You should provide a minimum of 7GB of disk space, which is less than the required 500GB from above.
This is because you can run a full node as a “pruned node” to achieve this reduced storage space. Pruning deletes old blockchain data so you have only the most current data downloaded. This comes with some small drawbacks.
You won’t be able to re-scan your wallet. If you want to use your full node with all its functionalities, you will need to download the blockchain data again.
For long-term operating, your hardware should have a bandwidth with upload speeds of at least 50 kilobytes per second. You can expect to upload up to 200GB of data per month and download up to 20GB from the Bitcoin network.
Your hardware should be further cooled adequately because it is recommended to run the system 24 hours a day with a minimum of 6 hours a day.
Network Speed and Amount of Connected Peers
The more peers are connected to the network and the faster the network speed, the more performance it provides.
Many peers increase the speed of data transfer across a network.
This is the case because more peers provide more resources for the network. The load per peer is therefore reduced, resulting in faster performance. It further ensures the stability of the network in case of one or more peers failing.
This helps to achieve a high availability of resources. You won’t be overloaded with the amount of data requiring you to improve your hardware, which always comes at a cost.
Bitcoin Node Average Syncing Times
The average syncing time depends on a variety of factors, such as your system type or the amount of data needed to be synchronized.
If you download the software for the first time, you will need to download the whole blockchain together with the software which requires 500GB of data.
If you would just have a download speed of 1 Mbps, this would take nearly two months to download. You would be done in about 12 hours with a download speed of 100 Mbps.
So the initial process heavily depends on your internet connection. The ongoing syncing times will depend in the same way.
The amount of data is less than the initial process, so it won’t be that big of a problem. But this discrepancy shows that if you need to have the current data as fast as possible, you have to provide fast internet connections.
Do not forget that you will use your internet speed for your everyday life which will need a big part of the bandwidth, too.
How to Set Up a Full Node?
To start your node, you will first have to download the current version of Bitcoin Core.
This is free and open-source software enabling you to run a full node in the Bitcoin blockchain.
Once you have downloaded the software on your local computer, you can download the blockchain with its data for the first time.
This process will take time as the data is currently about 500GB big and could take several days depending on the internet speed you have. This effort will give you access to all features of Bitcoin and you will help to secure the network.
You will support the network too with your bandwidth and your node as another part of the decentralization of the blockchain.
Why is Bitcoin Core Not Syncing?
It can happen that your node is not syncing, which can be a frustrating issue.
Without proper syncing, you could not be able to do a maybe important transfer, as it often happens in such situations.
There could be several reasons Bitcoin Core may not sync. It could go from an outdated version of your wallet over an incorrect setting or connectivity problem of your internet provider or the blockchain servers.
There are some general steps for troubleshooting you could try in this situation. Always check in the first if you’re using the most up-to-date version of the client. Then you should check if your network works properly.
Sometimes it seems that your devices are connected to the internet, but the internet is down at that moment.
If these factors are working properly and you still have issues, then something more serious could be the issue. Here, contact a support team to get further help.
How Long Does Bitcoin Core Take to Download?
For the download of the Bitcoin Core, you need to download the whole blockchain data for the first time.
This requires a download of about 500GB, which is a massive amount of data with over ten years of transaction history.
It is hard to predict the actual time to download this amount of data. The actual time needed will heavily depend on the internet connection you have at your disposal.
It could go from several hours up to several days for the entire blockchain to be downloaded onto your device. Keep in mind that you always download the complete transaction history.
With every new day, additional data gets into the blockchain and makes the initial download even bigger.
Conclusion: How Long Does It Take Bitcoin Core to Sync?
The time it takes for Bitcoin Core to sync depends on various factors such as computer specifications, internet speed, and available storage. The initial synchronization can take several days due to the large amount of data that needs to be downloaded.
Understanding the synchronization process helps in planning resources efficiently and setting realistic expectations. Faster internet connections and powerful hardware can significantly reduce syncing times. Keeping the Bitcoin Core wallet synchronized ensures the most up-to-date and secure access to your funds.
