Knowledge Notes | Layer 2 Networks
① Optimistic Rollups assume submitted results are valid, while allowing a challenge period. With the official cross-chain bridge, withdrawals to the mainnet generally take about 7 days.
② In March 2024, Ethereum’s Dencun upgrade introduced blob data (EIP-4844), making it much cheaper for Layer 2 networks to submit data to the mainnet.
③ Before withdrawing assets from a Layer 2 network to the mainnet, check whether you’re using the official bridge or a third-party cross-chain bridge—the transfer speed and risks differ.
