Are you curious about the size of a blockchain? We’ll go through all there is to know about blockchain size, including its limits and if it can cause problems in the future. Blockchain is well-known for its ability to transform the world around us. It provides immutability, transparency, and unrivalled security that no other technology has previously been able to provide. After all, it affects how we define processes, store data, and investigate the security of the network on which the program runs.

However, there is one major issue: blockchain block size. Let’s take a look at how the blockchain works to get a better grasp of the issue.

There is no centralized authority in any blockchain network. The network’s decentralization is aided by peer participation. A copy of the ledger is kept by each peer (where all transactions are stored). This means that if a new transaction occurs, the ledger on each node will be updated. The one-of-a-kind solution enables enterprises to build decentralized networks capable of solving previously unsolvable problems.

The Size of the Blockchain Ledger Is a Major Issue

However, blockchain is not without flaws. Because there are just a few peers linked to the network, the blockchain block size was not as large at first. The bitcoin blockchain, for example, was 614 MB in size in 2012. However, the bitcoin blockchain has already expanded to 250K MB in size. Each peer/node is responsible for around 250 GB of data. This leads to difficulty with the size of the bitcoin blockchain.

The same issue affects other blockchain networks as well. Ethereum’s blockchain has already surpassed 1 TB in size.

What is the limit to the size of a blockchain?

The bitcoin blockchain ledger has increased from 150 GB to 250 GB in the last two years. That’s nearly 50 gigabytes every year. By 2030, the size of a blockchain ledger might potentially exceed 1 TB. However, not every node needs to download the entire blockchain to become operational. Some people join the blockchain network to make transactions rather than to validate them.

Some nodes are referred to as “full nodes.” Full nodes are necessary for individuals who want to participate in the ongoing transaction’s validation. This requires them to download the entire 250 GB blockchain data set, which includes block headers and transactions.

Furthermore, the current size limit for bitcoin blockchains is 1 MB. Some of the space inside this limit, however, is unusable. As a result, you’ll have to deal with the bitcoin blockchain size restriction as is. The issue of Ethereum’s blockchain ledger size was more serious than that of bitcoin. A bitcoin investor, Alistair Milne, expressed concern about the scale of the Ethereum ledger compared to bitcoin. Ethereum is expanding at three times the rate of bitcoins, according to a picture he shared.

However, this isn’t entirely true, as Ethereum also provides ways to interact with the ledger. Pruning is a notion that allows nodes to work without having to download the entire blockchain data.

Does the size of a blockchain matter?

Yes, the size of a blockchain ledger is important. Blockchain is a relatively new technology that is expected to gain in popularity in the future years. Because Bitcoin is first-generation blockchain technology, it is not without flaws. It has issues with scalability and size. Scalability is becoming a challenge as the blockchain grows in size. It has been one of bitcoin’s most serious problems. To temporarily address the issue, they implemented the SegWit2x hard fork to increase block size (at the granular level) and improve bitcoin’s scalability and performance.

The size of the ledger is expected to grow significantly, with estimations of 6.5 TB by January 2023. It will necessitate the purchase of larger disk space in order to participate in the network. However, Moore’s law predicts that hard disk storage prices will fall over time, allowing you to purchase less expensive storage. The biggest issue emerges when the rate at which the blockchain grows outpaces the rate at which storage becomes cheaper.

It will be difficult for enthusiasts to contribute their skills or ideas to the network. Contributors will have to pay thousands of dollars to get their nodes up and operating, which may or may not be worthwhile.

What Are the Consequences of a Large Blockchain Size?

We live in a world where transactions are king. Non-cash payments in the billions are made every day. The rate of growth of transactions is quadratic. However, with cryptocurrencies such as bitcoin, Ethereum, NEO, and others, we’re seeing a shift in how non-traditional channels are used to conduct transactions.

Compared to Visa or other forms of transactions, bitcoin does not now have to account for many transactions. However, if bitcoin is utilized for every transaction, each block might consume up to 2.4 terabytes, not to mention the fact that blockchain can generate one block every ten minutes. In other words, 2.4 terabytes of data will be added to the blockchain size every 10 minutes. 350 GB is added daily, and 127 TB is added yearly. This also implies that there is no limit on the number of ledgers.

The issue limit creates new issues. These figures give cause for alarm. Furthermore, miners will take longer to solve a block because the block size will grow exponentially, leading to slower transactions. On the contrary, cheap hardware is our only hope in the foreseeable future. Terabytes of storage will not be a problem, and computing power will continue to rise rapidly, making transaction validation much easier.

What Impact Will It Have on Blockchain-Based Projects?

Is the problem affecting startups that are developing applications on Ethereum and bitcoin? It all relies on how the two blockchain technologies progress over time. Startups should not be concerned with their scale at this time. The Ethereum blockchain already has pruning, which reduces the amount of blockchain data required by a complete node. Bitcoin, on the other hand, does not yet allow pruning. The whole node status will be lost if someone prunes the bitcoin.


The size of the blockchain isn’t the most pressing issue that needs to be addressed. In fact, the main focus right now is on scalability and transaction speed. So, what are your thoughts on the scale of blockchain ledgers, such as bitcoin and Ethereum? There is also a slew of other blockchain projects to conserve space and make it as efficient as possible.
