Med Chain aims to create a new trading lifestyle of C2M through the decentralization, non-tamperable and traceability of blockchain, combined with the actual situation of the e-commerce industry, reducing the transaction cost of consumers and improving the production efficiency of manufacturers. Globalized peer-to-peer trading is integrated into every aspect of life, and everyone can trade and everything can be traded. Peer-to-peer trading lifestyle: Med Chain expects to popularize C2M trading models into people's daily lives through blockchain technology, open up trust barriers between consumers and manufacturers, reduce trust costs, and achieve peer-to-peer customized e-commerce transactions. Global e-commerce bottom-level public chain: Med Chain expects to use POS and DPOS consensus mechanism to establish a global e-commerce transaction public chain, establish a transaction credit system based on blockchain technology, product copyright traceability system, intelligent payment system, and transaction after-sales arbitration system. The open data system is open to global developers, allowing blockchain technology to serve all walks of life in e-commerce.
Ankr strives to build a resource efficient blockchain framework that truly enables Distributed Cloud Computing (DCC) and provides user-friendly infrastucture for business applications. There are indeed existing cloud solutions, but Ankr is the first one to leverage both blockchain and trusted hardware. Technology Overview Ankr provides a computation-resource-efficient blockchain and an integrated data feed system leveraging both cryptographic primitives and trusted hardware Proof of Useful Work The Proof of Useful Work (PoUW) consensus enables a self-sustainable blockchain framework. Instead of wasting electricity and computing power on hashes like Bitcoin does, PoUW uses these resources towards useful work tasks provided by enterprises and consumers. The protocol runs on SGX-enabled CPUs with remote attestation to ensure security and confidentiality. The novel PoUW approach unlocks the massive potential of idle computing power around the world by providing enough incentives: in this scheme, every computation contributor gets compensated, and some will get the extra reward for generating the blocks. In the future, this mining scheme can promote Universal Basic Income (UBI). Plasma Sidechains The Multi-chain Plasma implementation allows different applications to handle application-specific smart contracts on individual side chains, preventing transactions from overloading the PoUW-based main chain. Native Oracle Service Native Oracle Service (NOS) provides authenticated data feed by leveraging both cryptographic primitives and the trusted execution environment (TEE). Through a standardized API to port data from existing websites, NOS enables simple real-world business adoption
