KeKChain is a cryptocurrency system that supports smart contracts without the scalability and privacy limitations of earlier systems such as Ethereum. KEK Chain, like Ethereum, allows parties to use code to create smart contracts that specify the behavior of a virtual machine (VM) that executes contract functions. KeK Chain strives to solve scalability and usability issues without compromising decentralization and leveraging the existing developer community and ecosystem. It is an off-chain/external extension solution for existing platforms, providing scalability and superior user experience for DApps/user functions.
