Arbitrum vs Avalanche
Avalanche and Arbitrum differ fundamentally, with Avalanche being a Layer 1 network featuring its "Avalanche consensus" mechanism for high throughput, decentralization, and security. AVAX is its native cryptocurrency. In contrast, Arbitrum is a Layer 2 solution built on Ethereum, leveraging its security and block space while utilizing an "optimistic rollup" consensus for high throughput, low costs, and robust security. DefiLlama provides a comparison of their Total Value Locked (TVL).
