zkWASM has the potential to become a technological innovation leading to the large-scale adoption of blockchain, opening a new world for Web3 by building high-performance, interoperable applications.

The technical keywords for this year's Devcon are basically ZK, L2, significant MEV, and the new hotspots should focus on Danksharding and AA (account abstraction).

The company is actively developing seven extension solutions, ranging from various ZK Rollups to sidechains, as well as software development kits (SDKs) and other engineering infrastructure.

Polygon has made a $1 billion commitment to zk scaling. Although the four scaling solutions are all based on zk technology, each has its own strengths and different strategies. So, what are the specific technical characteristics and development progress of these four solutions?
