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.
The ShipChain platform is based on a simple, yet powerful solution called 'Track and Trace.' Our ecosystem will encompass all methods of freight, and will include an open API architecture that can integrate with existing freight management software. The ShipChain platform unifies shipment tracking on the Ethereum blockchain, using a sidechain to track individual encrypted geographic waypoints across each smart contract. With this system, the meaning of each cryptographic waypoint is only accessible for interpretation by the parties involved in the shipment itself. This gives shippers more visibility across their supply chain, and allows carriers to communicate with ease. Information about loads, geo waypoints, and other basic information is recorded and publicly validated within the sidechain. On the shipment's delivery and confirmation, the contract is completed and stored on the main blockchain.
