Then, copy that formula down for the rest of your stocks. But, as I said, dividends can make a huge contribution to the returns received for a particular stock. Also, you can insert charts and diagrams to understand the distribution of your investment portfolio, and what makes up your overall returns. If you have data on one sheet in Excel that you would like to copy to a different sheet, you can select, copy, and paste the data into a new location. A good place to start would be the Nasdaq Dividend History page. You should keep in mind that certain categories of bonds offer high returns similar to stocks, but these bonds, known as high-yield or junk bonds, also carry higher risk.

The Bitcoin blockchain currently stands at around GB, and it is growing at a similar rate to Ethereum. This means that if you want to download and store an entire copy of either blockchain, you will need significantly more storage space for Bitcoin. Bitcoin Blockchain Size The Bitcoin blockchain is a public ledger that records all bitcoin transactions.
Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the blockchain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. As of May , the size of the Bitcoin blockchain was about gigabytes. Ethereum Blockchain Size The Ethereum blockchain is expected to reach 1 TB in size by the end of , according to a new report from Arcane Research.
The research firm estimates that the blockchain will grow at an average rate of 50 GB per month over the next three years. The growth of the Ethereum blockchain has been driven by the rise of DeFi decentralized finance applications, which have seen explosive growth in As the Ethereum blockchain grows, so does the amount of data that needs to be stored and processed by nodes.
This could eventually lead to scalability issues, as the network may struggle to process all transactions in a timely manner. Recently, Microsoft announced that it was adding support for Ethereum wallets and smart contracts on its Azure cloud platform.
This is a five-fold increase from July , when it was around 4 GB. The reason for this growth is due to the increasing number of transactions on the Ethereum network. In December , there were over 18 million transactions on Ethereum, which grew to over 24 million by January The growth in transaction volume has led to an increase in storage requirements for the full Ethereum blockchain.
Each transaction requires about bytes of data storage. As such, the 20 GB blockchain size can store approximately 40 million transactions. The Ethereum blockchain size is expected to continue growing as the number of transactions on the network increases. If transaction volume grows at the same rate as it did in , then the blockchain size would reach 30 GB by December However, if transaction volume grows at a faster rate, then the blockchain size could reach 50 GB or even GB within a few years.
The increasing blockchain size may eventually become a problem for some users who want to run a full node on their computers. A full node stores the entire copy of the blockchain and thus requires a lot of storage space. As such, users with limited storage space may not be able to run a full node in future years unless they have access to cheaper storage solutions or are willing to prune old blocks from their local copy of the chain.
Conclusion The size of the Ethereum blockchain has been a hot topic recently. Some people are concerned that it is growing too quickly and may become unmanageable in the future. Others believe that the current size is not a problem and that the Ethereum network can handle it. The debate came to a head recently when a user on Reddit asked if anyone knew how big the Ethereum blockchain was currently.
The question quickly garnered over 1, responses, with many people chiming in with their own thoughts on the matter. So, what is the truth? Especially considering that almost any action a user takes on Ethereum requires a digital signature, which takes up a lot of space. Ethereum is currently therefore generating far more data than Bitcoin, however Bitcoin still has more cumulative blockchain data, as the chart below shows. Finally, from late onwards, the Ethereum blockchain growth rate accelerated further and the growth rate is now far higher than Bitcoin.
While it may be surprising to learn that the Ethereum blockchain is smaller than the Bitcoin blockchain, it seems that it is a bias towards the present and failure to remember just how small Ethereum was a few years ago, which is the primary cause of this surprise, in our view. This includes all the digital signatures authorising each transaction. In the case of Ethereum and Geth we tested the inclusion of the signatures, by disconnecting our Geth node from the internet and successfully retrieving the digital signatures from various sample transactions, including ones from and The Ethereum blockchain data also includes all the code necessary to deploy every smart contract and we also tested the presence of this code on our local machine, which had a few hundred GB of storage.
What is the 9TB Ethereum blockchain? As far as we can tell, this larger data size is because the node stores and indexes results from historic states of the network in memory. All these results can be calculated from the smaller blockchain data set. When looking up a recent transaction hash on our non-archival Geth node with the following command, we obtained a successful result: eth. However, we can still obtain data from these older transactions by requesting their position in a particular block.
The transaction signature is also displayed. We received some questions on why this is so large compared to the somewhat equivalent or analogous metric in Bitcoin, the UTXO set size, the set of unspent Bitcoin outputs. The last block and the state head or UTXO set is all a node needs to assess the validity of an incoming block, in the case of Ethereum and Bitcoin respectively.
Bitcoin Core supports pruning the blockchain, where a node can discard old blockchain data and only retain some very recent transactions plus the UTXO set. This means that one can fully validate the entire Bitcoin blockchain and check the validity of new blocks, with well under 10GB of disk space. This is a pretty neat feature and represents a strong efficiency.
For instance, 4. This efficiency does not seem to apply to Ethereum. It is fair to say that as far as we know, the Ethereum developers have not tried to make this more efficient, as there have been other priorities, but even if they did attempt this, they would be unlikely to achieve the efficiency savings that one can see in Bitcoin.
The state is computed from the transaction history and essentially contains: all Ethereum account balances, storage associated with every deployed Ethereum smart contract and account nonces. The state is updated and computed after each block, based on the previous state and the new transactions in the block. A merkle root hash of the state is included in each block header, ensuring consensus of the network state.
The state data continues to grow as Ethereum progresses and as mentioned above, the latest state is comparable in size to the blockchain itself. If a node was to store all the complete states, for every block, this would be a gigantic amount of data, perhaps significantly larger than even the 9TB archive node. An individual Ethereum transaction could have a very small impact on the state or a large impact on the state.
