The Vibe: The individual blockchains people use to send crypto, run apps, and trade — each network is its own separate system with its own rules, speed, and coins.
The Details: A blockchain network is a live, distributed system of computers (nodes) running the same software to maintain one shared ledger. Each network has:
- Its own native coin (e.g., BTC for Bitcoin network, ETH for Ethereum network).
- Its own consensus mechanism (PoW, PoS, PoH).
- Its own speed, fees, and features (e.g., Ethereum for smart contracts, Solana for high TPS).
Major networks in 2026: Bitcoin, Ethereum, Solana, BNB Chain, Avalanche, Polygon, Arbitrum, Base, Optimism. Networks can interact via bridges, but they’re separate worlds — sending to the wrong network loses funds forever.
Pro Tip: Always double-check the network before sending (e.g., Ethereum Mainnet vs Arbitrum). Use wallets with clear network selectors (MetaMask, Phantom). Explore different networks via explorers (Etherscan, Solscan, Arbiscan) to see real activity.
