Polkadot vs Solana FAQ
- What is Polkadot?
- Polkadot (DOT) is a sharded multi-chain network launched in 2020 by Gavin Wood (Ethereum co-founder, Parity CEO). Its Relay Chain provides shared security for connected parachains, each of which can specialise its own logic and governance.
- What are Polkadot parachains?
- Parachains are application-specific L1-like chains that lease a slot on Polkadot for a fixed term by bonding DOT. Examples: Acala (DeFi), Moonbeam (EVM compatibility), Hydration (liquidity). Recent Polkadot 2.0 moves toward "coretime" — renting blockspace per block.
- What is Solana?
- Solana (SOL) is a high-throughput blockchain launched in 2020. It combines proof-of-stake with a clock-like mechanism called Proof of History to process thousands of transactions per second at sub-cent fees, making it popular for DeFi, NFTs, and memecoins.
- Why does Solana have low fees?
- Solana processes transactions in parallel and compresses state into a single global chain, rather than splitting workload across L2 rollups like Ethereum does. The trade-off is higher hardware requirements for validators and occasional network congestion.
- How do Polkadot and Solana compare?
- Polkadot (DOT): Sharded multi-chain network. Parachains share relay-chain security. Launched 2020, runs Nominated Proof-of-Stake. Solana (SOL): High-throughput Layer 1. Sub-cent fees, consumer-scale apps, memecoin volume. Launched 2020, runs Proof-of-Stake + Proof-of-History.
