EIDK is a public blockchain system developed based on the MimbleWimble protocol, with scalability and privacy as our core competencies. It is a domestically-developed public chain in China that offers anonymity and privacy while also being auditable. The public chain token can only be obtained through PoW mining. This token represents the technological value and future potential of the EIDchain public chain. In 108 years, EIDK will have a fixed issuance of 1 billion tokens, with no pre-mining, no ICO, and no further issuance ever. It is primarily designed for use in government and enterprise blockchain transformation applications, playing a significant role in digitalizing equities, fixed assets, cultural products, financial privacy, and corporate blockchain governance.
