+## Polkadot Comparisons
+
+- Ethereum: Polkadot realized Ethereum's scaling vision, first delivered by co-founder Dr. Gavin Wood. [^51]
+- Solana: Unlike Solana, Polkadot scales without compromising Web3 principles of decentralization and security.[^52]
+- Cosmos: Unlike Cosmos, Polkadot provides shared security and secure interoperability.[^53]
+- Avalanche: Subnets in Avalanche are not as flexible as applications on Polkadot, and subnets do not provide shared security or secure interoperability.[^54]
+- Layer 2s: Layer 2 solutions face performance issues, unpredictable fees, and fragmented interoperability due to non-native support for rollups.[^55]
