Andreessen Horowitz's cryptocurrency division a16z crypto has launched two new SNARK-based technologies, Lasso and Jolt, which provide a more efficient approach to SNARKs design that may make it faster and easier for developers to understand, potentially promoting the development of ZK-rollups in Layer 2.
The article states that Lasso uses a "find parameter" mechanism that facilitates faster zero-knowledge proofs. Jolt is a framework designed for Roll-ups compatible with the Ethereum Virtual Machine. It is described as a novel approach to building a SNARK VM (virtual machine execution via SNARK proof) using Lasso.
