Ethereum uses a Key-Value based DB (leveldb). By using the hashed value of the address as the key and using the address as the path as shown in the picture on the below, you can find out the state value of the account. Ethereum Tries The Tries used in Ethereum are Storage Trie, State Trie, Transaction Trie, and Receipts Trie. Among these, the Root Hash value stored in the Block Header is State T..

ERC-721 is a standard for non-fungible tokens (NFTs) on the Ethereum blockchain. NFTs are unique digital assets that cannot be replicated or replaced. This is in contrast to fungible tokens, such as ERC-20 tokens, which are interchangeable and can be replaced with one another. ERC-721 tokens are often used to represent digital collectibles, such as artwork, music, or game items. They can also be..

In Etherscan, "Verify" is a process that allows developers to upload the source code of their smart contracts to the Etherscan website. Once the source code is uploaded, Etherscan will match it with the bytecode that is deployed on the Ethereum blockchain. If the source code and bytecode match, the contract will be verified. Verifying a contract has several benefits: It provides transparency for..

ERC-20 is a technical standard for fungible tokens on the Ethereum blockchain. Fungible tokens are interchangeable with each other, meaning that one token is worth the same as any other token of the same type. This is in contrast to non-fungible tokens (NFTs), which are unique and cannot be replaced. The ERC-20 standard defines a set of rules that all ERC-20 tokens must follow. These rules inclu..

Externally Owned Accounts (EOAs): These accounts are controlled by private keys and are typically used by individuals and businesses to store and send Ether and other ERC-20 tokens. Contract Accounts (CAs): These accounts are controlled by smart contracts and are typically used to implement decentralized applications (DApps) and other complex functionality. Here is a table that summarizes the ke..

The GHOST protocol (Greedy Heaviest Observed Subtree) is a chain selection rule that is used in the Ethereum blockchain. It is a modification of the longest chain rule, which was the original chain selection rule used in Ethereum. The GHOST protocol was introduced in 2013 as a way to improve the security of the Ethereum blockchain. It does this by making it more difficult for attackers to mine e..
