📎 Blockchain Industry | Layer 2 Networks
· Key point: Optimistic Rollups initially assume that submitted results are valid, while providing a challenge period. Withdrawing to the mainnet via the native bridge generally takes around 7 days.
· Why it matters: Layer 2 security relies heavily on the Ethereum mainnet: transaction data and proofs are ultimately posted to the mainnet. This is a key difference between Layer 2 networks and independent blockchains.
· Note: Before withdrawing assets from Layer 2 to the mainnet, check whether you’re using the official bridge or a third-party cross-chain bridge; processing times and risks differ.
