What is Ethereum?

Ethereum is a decentralized blockchain platform enabling developers to build decentralized applications (DApps). Its hallmark feature is smart contracts—self-executing agreements that trigger actions when predefined conditions are met.

To grasp Ethereum, start with Bitcoin. Bitcoin pioneered a public, shared ledger for peer-to-peer transactions without intermediaries. Ethereum expands this vision by offering a flexible platform for blockchain-based solutions across industries. Think of Ethereum as an "iOS for DApps," where developers can deploy applications using Solidity, Ethereum’s programming language.

Key Features:

• Smart Contracts: Automate processes (e.g., payments, agreements) without third parties.
• Decentralization: No single entity controls the network.
• Ethereum Virtual Machine (EVM): Executes smart contracts using Ether (ETH) as "fuel."

Ethereum Smart Contracts

Smart contracts are digital "if-then" agreements. For example:

"If it’s the 1st of the month, transfer $3,000 from Parent’s Account to Child’s Account."

This eliminates banks from the process, ensuring transparency and efficiency.

How Smart Contracts Work:

• EVM: The runtime environment for smart contracts on Ethereum nodes.
• Gas Fees: Paid in ETH to execute contracts (e.g., $1–$50 per transaction).

Ethereum Tokenomics

• Annual Issuance: Capped at ~18 million ETH (25% of initial supply).
• Deflationary Design: Lost ETH (e.g., forgotten keys) reduces circulating supply.
• Block Rewards: 2 ETH per block (~13,400 ETH mined daily).

ETH as Fuel: Like oil, ETH powers the Ethereum "engine." More DApps = higher ETH demand.

Ethereum DApp Examples

1. DNN: Decentralized news platform rewarding users for fact-checking.
2. uPort: Self-sovereign digital identity system.

Ethereum Ecosystem

• Enterprise Ethereum Alliance (EEA): 400+ members (Microsoft, JPMorgan) developing enterprise blockchain standards.
• Ethereum Foundation: Nonprofit supporting Ethereum’s development and upgrades.

Ethereum Upgrades: Cancun-Deneb (2024)

Focuses on:

• EIP-4844 (Proto-Danksharding): Lowers Layer 2 transaction costs.
• Scalability: Prepares for future "sharding" to increase throughput.

Vitalik Buterin

• Founder: Advocated for decentralization post-Bitcoin.
• Quote: "Trust is complicated… Ethereum removes the need for it."

Gavin Wood

• Co-founder: Authored Ethereum’s "Yellow Paper" and created Solidity.

FAQs

1. How is Ethereum different from Bitcoin?

• Bitcoin is digital cash; Ethereum is a platform for programmable contracts/DApps.

2. What’s the purpose of Ether (ETH)?

• ETH pays for transactions and smart contract execution ("gas fees").

3. Can Ethereum be mined?

• Yes, but it’s transitioning to Proof-of-Stake (PoS), making mining obsolete.

4. What is Ethereum 2.0?

• An upgrade improving scalability, security, and sustainability via PoS.

5. How secure is Ethereum?

• Extremely secure due to decentralization, but smart contract bugs can pose risks.

6. What are Layer 2 solutions?

• Networks (e.g., Arbitrum, Base) built atop Ethereum to reduce fees and speed up transactions.

Latest Ethereum News (April 2024)

• Base TVL Hits $4B: Coinbase’s Layer 2 surpasses Ethereum in monthly transactions.
• Restaking Risks: EigenLayer’s $124B TVL highlights growth and potential vulnerabilities.
• Vitalik’s Vision: Post-Dencun, Ethereum focuses on Rollup optimization.
