Economic Utility: Meaning, Types, Examples

Economic utility is the value or satisfaction a person gets from consuming a good or service. It comes in four main types: form, time, place, and possession utility.

Edge computing

Edge computing is a distributed computing paradigm that brings computation and data storage closer to the location where it is needed, improving response times and saving bandwidth. Instead of relying solely on centralized data centers, edge computing processes data at or near the source of data generation, such as IoT devices, sensors, or local servers. This approach enhances real-time data processing, reduces latency, and increases the efficiency of applications, particularly those requiring immediate data analysis and decision-making, such as autonomous vehicles, smart cities, and industrial automation.

EIP-1559

EIP-1559, or Ethereum Improvement Proposal 1559, is a significant upgrade to the Ethereum blockchain's transaction fee mechanism. Implemented in August 2021 as part of the London Hard Fork, it introduces a base fee that dynamically adjusts based on network congestion, aiming to make transaction fees more predictable and reduce volatility.

Electronic Check (Echeck)

An electronic check, or eCheck, is a digital version of a traditional paper check used to make payments online. It allows funds to be electronically transferred from a payer's bank account to a payee's account through the Automated Clearing House (ACH) network.

Electronic Funds Transfer (EFT)

Electronic Funds Transfer (EFT) is a digital payment system that allows the transfer of money between bank accounts electronically, without the need for paper-based transactions. It is commonly used for direct deposits, online bill payments, and transferring funds between accounts, providing a fast, secure, and efficient way to handle financial transactions.

Electrum wallet

Electrum Wallet is a lightweight Bitcoin wallet known for its speed and efficiency. It was created in 2011 and is designed to be simple to use while providing advanced features for experienced users. Electrum connects to decentralized servers to retrieve blockchain information, ensuring quick transactions without needing to download the entire blockchain.

Elliott Wave Theory: Patterns, Cycles, and How It Works

The Elliott Wave Theory is based on the idea that market prices move in repeating patterns. Learn how motive and corrective waves form market cycles and how traders use Fibonacci ratios with it.

End-to-End Encryption

End-to-end encryption is a method of secure communication that prevents third parties from accessing data while it's transferred from one end system or device to another.

Enterprise blockchain

Enterprise blockchain refers to the use of blockchain technology within a business or organizational context to enhance transparency, security, and efficiency in operations. Unlike public blockchains, which are open to anyone, enterprise blockchains are typically permissioned, meaning that only authorized participants can access and interact with the network.

Erasure Coding

Erasure Coding is a data protection method that breaks data into fragments, encodes them with redundant pieces, and distributes them across different locations to ensure data can be reconstructed even if some fragments are lost or corrupted.

ERC-1155

ERC-1155 is a versatile Ethereum token standard that allows for the creation and management of multiple types of tokens within a single smart contract. Unlike its predecessors, ERC-20 and ERC-721, which are designed for fungible and non-fungible tokens respectively, ERC-1155 supports both types, enabling more efficient and flexible token management. This standard is particularly useful for applications like gaming, where a single contract can handle various in-game assets, such as currencies, weapons, and collectibles, all with different properties.

ERC 721

ERC-721 is a non-fungible token (NFT) standard on the Ethereum blockchain. Unlike ERC-20 tokens, which are fungible and identical, each ERC-721 token is unique and can represent ownership of a specific item or asset, such as digital art, collectibles, or in-game items.

Ethash: Ethereum's Pre-Merge Proof-of-Work Algorithm

Ethash is the Proof-of-Work algorithm that secured Ethereum until The Merge in 2022 and still secures Ethereum Classic. Learn how Ethash mining works.

Ethereum ETF

An Ethereum ETF is an exchange-traded fund that tracks the price of Ethereum, allowing investors to gain exposure to the cryptocurrency without directly owning it.

Event-Driven Architecture (EDA)

Event-driven architecture (EDA) is a software design paradigm that focuses on the production, detection, consumption, and reaction to events. In this architecture, events are significant changes in state or conditions that are communicated between decoupled components or services. EDA enables systems to be more responsive, scalable, and flexible by allowing components to act independently and asynchronously, reacting to events as they occur. This approach is commonly used in real-time applications, microservices, and distributed systems to enhance performance and adaptability.

Event sourcing

Event sourcing is a software architectural pattern where state changes in a system are captured as a sequence of events. Instead of storing just the current state, every change is recorded as an immutable event, allowing the system to reconstruct past states by replaying these events.

Event Stream Processing

Event stream processing is a real-time data processing technique that involves the continuous capture, analysis, and management of data streams as they are generated. It enables organizations to process and analyze high volumes of data in motion, allowing for immediate insights and actions.

Execution latency

Execution latency refers to the time delay between the initiation of a command or task and its actual execution or completion. It is a critical performance metric in computing and networking, as it affects the responsiveness and efficiency of systems.

Execution speed

Execution speed refers to the rate at which a computer program or system performs tasks or processes instructions. It is a critical factor in computing, affecting the efficiency and responsiveness of software applications.
