Ethereum Block Space: Bitcoin QT and Its Hashrate Breakdown
As a cryptocurrency enthusiast, you are probably familiar with the concept of block space in blockchain technology. In this article, we will look at how much space Ethereum takes up per day and hour when Bitcoin QT is running on your computer.
Background
Ethereum is a decentralized platform that allows developers to create, deploy, and execute smart contracts and decentralized applications (dApps). Its native cryptocurrency, Ether (ETH), has gained significant popularity in recent years. Bitcoin QT, also known as BQ9, is a popular implementation of the open-source blockchain Ethereum.
Block Space
To understand how much space Ethereum takes up, we need to consider the total block space of its network. According to estimates, the current block space on the Bitcoin QT mainnet is around 20 GB (1 TB). This means that each time a new block is created, it adds approximately 0.0004 GB (40 MB) of new data to the total block space.
Daily Space Usage
To calculate how much space Ethereum takes up each day when running Bitcoin QT on your computer, the following factors must be considered:
- Number of blocks added per day
- Average size of each new block
Assuming an average block size of 1 MB (1000 KB), which is a common estimate for Ethereum transactions, the following is a breakdown of daily space usage.
- Number of blocks added per day: approximately 200-300 blocks (source: Bitcoin QT blockchain data)
- Average block size: 1 MB
- Daily block space usage: approximately 200-300 MB
Converting this to GB, we get:
- Daily block space usage: approximately 0.00016-0.00029 GB
Hourly space usage

To calculate how much space Ethereum takes up per hour when Bitcoin QT is running on your computer, we need to consider the following factors:
- Number of hours per day
- Average size of each new block per hour (assuming an average block size of 1 MB)
Assuming an average block size of 1 MB and 24 hours per day, here is the hourly space usage breakdown:
- Number of blocks added per day: approximately 200-300 blocks (source: Bitcoin QT blockchain data)
- Average block size per hour: 1000 KB
- Hourly block space usage: approximately 200-300 MB
Converting this to GB, we get:
- Hourly block space usage: approximately 0.000016-0.000029 GB
Conclusion
Finally, the Ethereum blockchain takes up approximately 20 GB of total block space on its mainnet when running Bitcoin QT. Assuming an average daily block size of 100 MB and an hourly block size of 1 MB, we estimate that the blockchain adds approximately 0.00016-0.00029 GB per day and 200-300 MB per hour.
While these estimates may seem small compared to other cryptocurrencies, they do show how much data is generated on the Ethereum network each day.
Tips and Tricks
- To reduce block space usage, consider enabling the « hard fork » feature in your Bitcoin QT installation. This will allow you to upgrade to a newer version of the blockchain without losing any transactions.
- Use a disk cleanup tool to remove unnecessary files and data from your computer.
- Consider using a different cryptocurrency that requires less space.
By following these tips and understanding how much space the Ethereum blockchain takes up, you can minimize its impact on your computer’s performance while still enjoying access to this powerful and popular blockchain platform.
