How To Store Data On Ethereum Blockchain?

Since 2009, we have heard a lot about Blockchain, its application and development. There are some positives and negatives to this technology. But, one thing in common is that this technology is evolving at a faster rate. When we talk about Blockchain, there is another parameter that we should not, that is data storage. We all know that Blockchain is a ledger that allows the exchange of information and this information is stored in the ledger. Well, our focus in this blog will be on Ethereum. It is not just a cryptocurrency, and much more. Up until now we have discussed the use cases of Blockchain, but here we will talk about storing data on the Ethereum Blockchain.

Ethereum blockchain

Ethereum is an open source Blockchain platform that allows the creation of decentralized applications and It is a distributed public blockchain network. Ethereum Blokchian is focused on providing a platform to seamlessly run code for any decentralized application.

Unlike Bitcoin, Ethereum Blockhian allows miners to work to earn Ether. Ether is a token that will enable the entire functionality of the system. In the Ethereum blockchain, there is another type of token used to pay miners; it is called gas. Every smart contact to do it requires a certain amount of gas to be sent to the miners to get it into the Blockchain.

We all know a lot about smart contracts and how they work. These pre-programmed contracts have certain conditions that are agreed upon between the two parties, when the conditions are met, the contract executes and the payment process takes place. Now the question here is how does the backend work here. How is data stored on the Ethereum blockchain? Well, let’s try to discover the answer up front.

How is data stored in Ethereum?

Data on the Ethereum Blockchain is stored using a tire data structure. Before we continue, we want you to know that it is completely understandable that permanent data such as mined transactions and temporary data such as account balances should be stored separately. Ethereum uses this trie data structure to manage temporary and permanent data. It can be said that Ethereum is like a bank.

Only after the transaction is confirmed is it recorded in the transaction trie. Temporary or temporary data such as account addresses are stored in a trie state, and it is subject to change and updates. Therefore, it makes complete sense if both temporary and permanent storage should be stored separately and thus we have three attempts to manage and store the data.

Describe specific

As mentioned above, Ethereum stores and manages data using a triplet. There are three types of triples in the Ethereum blockchain:

  • State Trie
  • Trie store
  • And the transaction Trie

Bang trie

You must know that there is only one State Trie, Global State Trie in Ethereum. It is updated continuously. The state trie consists of a key and a value for every account present on an Ethereum account. This key is a 160-bit identifier.

Storage memory

As the name itself indicates, storage is where contract data is located. Every ethereum account has its own storage trio. The 256-bit hash of the root node of the storage trie is stored in the global state trie, StorageRoot.

Transaction Trie

Every Ethereum block has its own transaction trie. Every block contains transactions. The order of transactions included in every block is based on the addition of transactions to the block. The location of the block never changes, the path of a particular transaction is through the index of where the transaction is located in the block. In a word, it means that you can locate a trade, you can go back the same path and get the same result.

An important point to note here is that data such as account balances are not stored directly in blocks. Only the root node hashes of the transaction trie, the receptor trie, and the state attempt are stored in the Blockchain.


Ethereum Blockchain works quite simply, dividing data permanently and temporarily in different attempts ensures that the data is safe and the data is easily manageable. Data is stored on the blockchain as a secure and easily accessible smart contract.
