How does Ethereum Store Data?
Ethereum stores data using a data structure called a trie (short for “Radix tree”). A trie is a tree-like data structure that is used to store data in a compact and efficient manner.
- In Ethereum, the trie is used to store the current state of the blockchain, including the balances of all accounts and the code and data of all smart contracts.
- Each node in the trie represents a single piece of data, and the root node represents the current state of the Ethereum blockchain.
- When a transaction is executed on the Ethereum blockchain, the trie is updated to reflect the changes in the state of the blockchain.
The three types of trie in the Ethereum Blockchain are:
- State Trie: State trie gets constantly updated and it consists of a key and a value for every account that is present in the Ethereum Account. The key is state trie is a 160-bit identifier.
- Storage Trie: Storage trie is the place where the smart contract is present. A 256-bit hash of the storage trie’s root node is stored in the global state trie as the storageRoot and every Ethereum account has its own storage trie.
- Transaction Trie: Every Ethereum block has its own transaction trie. Every block contains the transactions and the path of a particular transaction is via the index of where the transaction resides in the block. Only the root node hashes of the transaction trie, storage trie, and state trie are stored in the Blockchain.
How to Store Data on Ethereum Blockchain?
Blockchain is a decentralized, distributed ledger that maintains a continuously growing list of records, called blocks. These blocks are linked and secured using cryptography, making it extremely difficult to alter or tamper with the data stored on the blockchain. This makes blockchain technology an ideal solution for storing data that needs to be secure, transparent, and tamper-proof.
Storing data on the Ethereum blockchain provides several benefits, including immutability, decentralization, and accessibility. When data is stored on the Ethereum blockchain, it is stored in a secure, tamper-proof, and transparent manner, making it an attractive option for businesses and individuals looking to protect their sensitive information. The article focuses on discussing how to store data on Ethereum Blockchain.
