This SNARK includes the proof of the validity of every transaction in the Rollup block.

Sophon is an entertainment-focused ecosystem built as a modular rollup leveraging zkSync’s ZK Stack technology. As a ZK chain leveraging the ZK Stack, Sophon is intended to be tailored for any high throughput applications such as artificial intelligence and gaming.

Reya Network  is a trading-optimized modular L2. Capital staked into Reya Network is used productively to support trading via a novel passive liquidity pool mechanism. This design creates instant shared liquidity for all exchanges operating within the Reya ecosystem. Margin engine logic is embedded into Reya Network itself, meaning users have a single margin account that can be used across multiple exchanges. Moreover, transactions are executed on a ‘first-in-first-out’ (FIFO) basis with zero gas fees, removing front-running and harmful MEV. The predecessor of this project, Voltz Protocol, was an automated market maker for interest rate trading.
