Via their Twitter handle, protocol and cross-chain bridge Polygon announced a new area of interest, ZK-based scaling solutions. In order to contribute and improve this approach to aggregate transactions into a blockchain, the project also announced a merger with Hermez Network and a $1 billion investment. Based on zero-knowledge proof, the layer 2 scaling solution called ZK-Rollups allows funds to be deposit into a smart contract on top of the Ethereum network. Thus, transactions can be securely processed off-chain and scalability can increase. As Polygon claimed in its official announcement, there is a high demand for Ethereum to improve its scalability. The project claims that their PoS based chain is “the best immediate solution” and relief for the increase in transactions fees and network congestion. They added: By establishing itself as one of the industry’s most popular and highest valued projects, Polygon proved that there is a lot of value to be created and captured by working on these hard challenges in symbiosis with Ethereum, instead of competing with it. The $1 billion investment will come directly from Polygon’s treasury and will use to hired and acquired “world-class” ZK-based projects and teams. In addition, the funds will be used for research, building, and adopting ZK-based solutions. Scaling solutions have 3 major challenges, the team behind Polygon argued security, decentralization, and privacy. These won’t ...
