Gas This refers to the value used for fees in Ethereum. The fee is calculated by converting the Byte Code that appears when the code in the Smart Contract is complied into the Gas value specified in the OP_CODE table. Gas Limit(Used) Gas Limit is divided into Block Gas Limit and Transaction Gas Used. Block Gas Limit means the sum of the total Transaction Gas Used in the corresponding block, and ..

EIP-2770 is a proposed Ethereum Improvement Proposal (EIP) aimed at standardizing the way meta transactions are executed within the Ethereum ecosystem. Meta transactions enable users to sign and submit transactions to the blockchain without having to pay the gas fees themselves. This can be beneficial for various reasons, like: Reducing barriers to entry: By removing the gas fee burden, EIP-2770..

Type: The type of transaction (e.g., LegacyTxType, AccessListTxType). PostState: The root hash of the world state after transaction execution. Status: The transaction's status (1 for success, 0 for failure). CumulativeGasUsed: Total gas used by the transaction and its sub-transactions. Bloom: A Bloom filter for efficient retrieval of logs matching specific topics. Logs: An array of logs emitted ..

Transaction is a structure used when EOA transmits Eth to EOA or when EOA calls CA. txType() byte: This method returns the type ID of the transaction. It is expected to return a byte representing the type of the transaction. copy() TxData: This method creates a deep copy of the transaction data, initializing all fields. It allows for the duplication of transaction data. chainID() *big.Int: Retur..

Block represents an Ethereum block. Note the Block type tries to be 'immutable', and contains certain caches that rely on that. The rules around block immutability are as follows: We copy all data when the block is constructed. This makes references held inside the block independent of whatever value was passed in. We copy all header data on access. This is because any change to the header would..

IndexedDB is a powerful API provided by web browsers for managing a local NoSQL database within client-side applications. Here's a detailed breakdown of its key features and functionalities: Purpose: Persistently store large amounts of structured data in the user's browser, enabling offline-capable web applications. Offer rich query capabilities for efficient data retrieval based on indexes. Key..

What It Is: A lightweight, serverless runtime environment designed for executing code closer to users, at the edge of the network. Built on a subset of standard Web APIs, prioritizing speed, security, and compatibility. Integrated into Next.js, offering specific features: Edge API Routes Middleware Server components (experimental) Key Characteristics: Minimal: Supports a smaller set of APIs comp..

In the case of Bitcoin blockchain, state values are managed based on UTXO. The user's balance is managed by updating the UTXO usage status whenever a new block is created. In the case of the Ethereum blockchain, the state value of balance data is stored in the Account based on the state, and the balance is updated every time a block is created. Types of Accounts: There are two main types of acco..

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..
