Ethereum (ETH)
What is Ethereum?
Ethereum is a decentralized, open-source blockchain platform that enables the creation and execution of smart contracts and decentralized applications (DApps). It was proposed by Vitalik Buterin in late 2013 and development was crowdfunded in 2014. The network went live on July 30, 2015, with 72 million pre-mined Ether (ETH), its native cryptocurrency.
How Does Ethereum Work?
1. Blockchain Technology: Like Bitcoin, Ethereum operates on a blockchain, a distributed ledger that records all transactions. However, Ethereum's blockchain is designed to be more versatile, supporting not just the cryptocurrency Ether but also programmable contracts and DApps.
2. Smart Contracts: Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automatically execute and enforce agreements when predetermined conditions are met, eliminating the need for intermediaries. These contracts run on the Ethereum Virtual Machine (EVM), a decentralized computing environment.
3. Ether (ETH): Ether is the native cryptocurrency of the Ethereum network. It is used to pay for transaction fees and computational services on the Ethereum network. Ether can be traded on various exchanges and used to interact with DApps.
4. Decentralized Applications (DApps): Ethereum enables developers to build and deploy DApps on its platform. These applications run on a decentralized network, providing enhanced security, transparency, and reliability compared to traditional centralized apps.
5. Proof of Stake (PoS) Transition: Ethereum is transitioning from a Proof of Work (PoW) consensus mechanism, similar to Bitcoin's, to a Proof of Stake (PoS) mechanism. This transition, known as Ethereum 2.0 or Eth2, aims to improve scalability, security, and energy efficiency.
Key Features of Ethereum:
Turing-Complete Programming Language: Ethereum uses a Turing-complete programming language, allowing developers to create complex and flexible smart contracts.
Decentralization: Ethereum operates on a decentralized network of nodes, reducing the risk of censorship and single points of failure.
Scalability: With the Ethereum 2.0 upgrade, the network aims to increase its scalability and transaction throughput.
Interoperability: Ethereum's standards, such as ERC-20 for tokens and ERC-721 for non-fungible tokens (NFTs), enable interoperability between different DApps and platforms.
Use Cases of Ethereum:
DeFi (Decentralized Finance): Ethereum hosts a wide range of DeFi applications, including lending platforms, decentralized exchanges, and stablecoins.
NFTs (Non-Fungible Tokens): Ethereum is the leading platform for creating and trading NFTs, which represent ownership of unique digital assets.
DAOs (Decentralized Autonomous Organizations): Ethereum supports the creation of DAOs, which are organizations governed by smart contracts and community votes.
Gaming and Virtual Worlds: Ethereum powers blockchain-based games and virtual worlds where users can own and trade digital assets.
