U.Today - Seasoned Ethereum (ETH) enthusiast and investor Ryan Berckmans published a thread to stress the main opportunities unlocked by noncustodial bridge mechanisms between various second-layer solutions. They are resilient to unexpected hardforks and can be far more resource efficient.
Inter-L2 bridges are more reliable and cheaper than competitors from L1s, Ryan Berckmans says
For instance, once the underlying L1 hard forks, both L2s on its top and their are automatically migrated. Meanwhile, a bridge between two L1s need manual migration initiated. When a paternal L1 reorganizes, all of its L2s follow; there's no need for any additional action.
Also, systems of interconnected L2 protocols can be more gas efficient compared to bridges from previous generations thanks to the integration of :
can be considered immutable only if we assume that both start and target L1 blockchains will never undergo hardforks.
Berckmans mentioned Hop Protocol, Across, Connext and Socket apps among the pioneering cross-L2 decentralized bridges.
Arbitrum strengthens its dominance in L2 scene with Stylus launched
As of today, 90% of Ethereum's L2s ecosystem is controlled by two blockchains, i.e., Arbitrum One (ARB) and Optimism (OP). As covered by U.Today previously, Arbitrum introduced , an instrument for programmers working in non-EVM languages.
With Stylus, developers can run smart contracts and tokens written in WASM languages (C, C++ and Rust) in EVM-compatible blockchains without limitations.
