DDK is a community platform that aims to create economic opportunities through the development of blockchain solutions. Since 2015, the DDK community claims to have contributed to a number of blockchain platforms.The DDK platform uses the Delegated Proof of Stake (DPoS) mechanism within its core. According to DDK, one of the advantages of a DPoS blockchain is that it depends on community members to participate in the maintenance and security of the platform so that each member’s participation provides benefit for all.
BitNew Chain (BTN), based on the system of peer-to-peer payments and smart contract, through forging a two-tier decentralized blockchain network with standard physical masternode, resource segregation, decentralized computing subsystem BTN-DC, and decentralized storage subsystem BTN-FS etc., aims to extend blockchain applications to the field of hardware.
