What is AltLayer?
AltLayer is an open and decentralised protocol for rollups. With AltLayer, we bring together a novel idea of Restaked rollup which takes existing rollups (spun from any rollup stack such as OP Stack, Arbitrum Orbit, ZKStack, Polygon CDK, etc.) and provides them with enhanced security, decentralisation, interoperability and crypto-economic fast finality.
Restaked rollups combines the ease of spinning up rollups using rollup stacks such as OP Stack, Arbitrum Orbit, ZKStack by ZKSync, Polygon CDK and others with the power of EigenLayer's restaking mechanism to bootstrap network security and build a decentralised network.
Restaked rollups are essentially a set of three vertically integrated Actively Validated Services (AVSes) created on-demand for a given rollup that works with any underlying rollup stack. These AVSes in conjunction offer three key services to rollups in particular to app-specific rollups:
Verification of rollups' state correctness
Faster finality
Decentralised Sequencing
The above services are provided via three modular components called:
VITAL (AVS for decentralised verification of rollup’s state)
MACH (AVS for fast finality)
SQUAD (AVS for decentralised sequencing)
