Key Features

Asset ownership

Ethereum is the global network where you control your assets, your data, and your identity.

Continuous operation

Ethereum has run continuously since 2015 without a single second of downtime.

Verifiable code

The code is open for anyone to verify. No company runs it, no one can shut it down, and thousands of independent operators keep it going worldwide.

Public rules

The code is public, agreements execute exactly as written. Think vending machine versus hoping the cashier gives correct change.

Open proposals

Changes happen through open proposals that anyone can participate in. Think community garden versus corporate farm.

Global access

Anyone, anywhere can use Ethereum. No permission needed.

Pros

Decentralized and censorship-resistant network with no single point of failure.
Open-source and transparent codebase allowing community verification and contributions.
Supports programmable smart contracts enabling diverse decentralized applications.
Permissionless access with no credit checks or account approvals.
Strong community governance and continuous development since 2015.

Cons

No official support team or help desk; users rely on community and documentation for assistance.
Transactions on the blockchain are final and irreversible, posing risks for errors or scams.
No explicit pricing plans; usage requires ETH for transaction fees which can fluctuate.
Complexity for new users due to blockchain and smart contract concepts.
Scams and fraud risks exist, requiring user vigilance and security awareness.
