The roadmap to 2023 for Klaytn, a blockchain platform for public services, is an ambitious one. It is divided into three phases: the Foundation Phase (2020-2021), the Expansion Phase (2021-2022), and the Maturity Phase (2022-2023). The Foundation Phase focuses on developing the platform, building the community, and creating partnerships. During this phase, Klaytn will launch its Mainnet, its own blockchain-based token, and its own wallet. The Expansion Phase will see Klaytn expand its network and services, with a focus on developing new applications and services, and introducing new features to the platform. Finally, the Maturity Phase will focus on further improving the platform and increasing the adoption of Klaytn services. This includes introducing new features, launching new products, and expanding the network. By 2023, Klaytn will be a mature platform with a wide range of services and applications.
