Positioned as a 'confirmation layer'
Allows different Rollup networks to read and trust each other's transaction data to accelerate cross-chain bridging of assets, decentralize the “sequencer”, a key component in Rollup, and enable low-cost storage of transaction data, providing key infrastructure for cross-chain composability.
Why is Espresso validation so important to enable composability?
Because when two chains are combinable, they need to be able to quickly acknowledge each other's state transitions in a reliable and neutral way.
Gold will always shine, looking forward to Espresso's performance, the future decentralization, coverage should be very wide.
Interaction opportunities: use the protocols on its ecosystem, or run nodes.
