FANTOM is a new DAG based Smart Contract platform that intends to solve the scalability issues of existing public distributed ledger technologies. The platform intends to distinguish itself from the traditional block ledger-based storage infrastructure by attempting to employ an improved version of existing DAG-based pro-tocols. The FANTOM platform adopts a new protocol known as the “Lachesis Protocol” to maintain consensus. This protocol is intended to be integrated into the Fantom OPERA Chain. The aim is to allow applications built on top of the FANTOM OPERA Chain to enjoy instant transactions and near zero transaction costs for all users. The mission of FANTOM is to provide compatibility between all transaction bodies around the world, and create an ecosystem which allows real-time transactions and data sharing with low cost.
Waltonchain is a genuine, trustworthy and traceable business ecosystem with complete data sharing and absolute information transparency. It is created by the combination of technologies of RFID and blockchain, which push forwards the integration of block chain and the Internet of Things. Waltonchain combines blockchain with IoT (specifically RFID) to create a management system for supply chains. The project is named after Charlie Walton, the inventor of RFID technology and a pioneer in the space. Logistics systems are complex and commonly involve several different parties. As these systems grow, it becomes increasingly tough for businesses in the same vertical to coordinate with each other. On top of that, individual entities may have different processes that further hinder the ability to transfer data back and forth. Waltonchain uses RFID identification to track products during each step of production and distribution. The data associated with each item is stored on an immutable blockchain that ensures its accuracy no matter where in the process it is.The Waltonchain team is loaded with supply chain experience. Do Sanghyuk, one of the co-founders, was previously the Director of the Korean Standard Products Association. The other co-founder, Xu Fangcheng was the Supply Chain Management Director of Septwolves Group Ltd. The team is getting support from their Chief Scientist Advisor, Kim Sukku – a former vice president of Samsung. Waltonchain has no shortage of partnerships – several of which are with Chinese provincial governments. The team is working with the Fujian government to create a “smart maritime” blockchain incubator, and with the Jinhu government to build smart air purification and monitoring systems. The Waltonchain architecture makes use of a novel consensus mechanism known as Proof-of-Stake & Trust (PoST). Waltonchain innovates on the traditional proof-of-stake (PoS) model and integrates a node reputation based system into the consensus mechanism. PoST provides for adjustable difficulty for each node, to ensure that integrity in the ecosystem is rewarded. Waltonchain also gives sub-chain developers the option to choose their own consensus mechanism, for example, sub-chains can strictly just have PoS as a consensus mechanism, and not PoST. Waltonchain, by use of its RFID technology, has introduced a novel way with which blockchain can solve not only the inefficiencies found with supply chain management, but also IoT.
