Introduction
Ethereum (ETH) is a decentralized platform renowned for its smart contracts and decentralized applications (dApps). Its native cryptocurrency, Ether, is widely used for transactions, investments, and DeFi services. Offline storage of ETH ensures maximum security against cyber threats. Popular methods include hardware wallets (Trezor, Ledger Nano X) and paper wallets.
Ethereum vs. Bitcoin: Key Differences
| Feature | Ethereum (ETH) | Bitcoin (BTC) |
|------------------|----------------------------------------|----------------------------------|
| Primary Use | Smart contracts, dApps | Peer-to-peer transactions |
| Consensus | Proof-of-work (transitioning to PoS) | Proof-of-work |
| Token Utility| Fuel for dApps (Gas fees in gwei) | Digital gold/store of value |
Ethereum Smart Contracts
Smart contracts automate agreements between parties without intermediaries. Benefits include:
- Decentralization: No reliance on banks or governments.
- Transparency: Terms are immutable on the blockchain.
- Efficiency: Reduces paperwork and delays.
Cold Storage vs. Hot Storage
Cold Wallets (Offline)
- Pros: Immune to hacking, ideal for long-term storage.
Types:
- Hardware Wallets: USB devices (e.g., Trezor, Ledger) with PIN protection.
- Paper Wallets: Physical printouts of keys (vulnerable to physical damage).
Hot Wallets (Online)
- Pros: Quick access for daily transactions.
- Cons: Higher risk of cyberattacks.
