Mainchains

Sidechains are independent blockchains linked to mainchains, like Bitcoin (BTC), to enhance functionality and scalability. Unlike mainchains, which focus on core security (e.g., BTC’s PoW ledger), sidechains like Liquid Network handle faster transactions or specialized tasks. $POL
Polygon (MATIC) acts as a sidechain for Ethereum (ETH), processing transactions off-chain to reduce fees and congestion. $ATOM
Cosmos (ATOM) uses sidechain-like zones for interoperability. Sidechains offer flexibility but rely on mainchain security, introducing risks like weaker consensus mechanisms or bridge vulnerabilities. MATIC’s PoS sidechain scales$ETH
ETH but faces centralization concerns. ATOM’s zones enhance modularity but require robust bridges. Mainchains prioritize security and decentralization, while sidechains trade some security for speed and innovation.
