Rocket Pool is a next generation decentralised staking network and pool for Ethereum 2.0 Rocket Pool is a self-regulating network of node operators; it automatically adjusts its capacity to match demand. The Rocket Pool protocol token is used to maintain an optimal capacity by: Increasing capacity when needed, by incentivising node operators to join. Decreasing capacity when not needed, by disincentivising node operators from joining. In addition to depositing ETH, a node operator is required to deposit a set amount of RPL per ether they are depositing. This RPL:ether ratio is dynamic and is dependent on the network utilisation. E.g: If the network has plenty of capacity, then node operators need more RPL to make deposits. It gets progressively more expensive in terms of RPL to make node deposits when the network does not have enough ETH from regular stakers to be matched up with node operators. This helps prevent several attack vectors outlined in the whitepaper and keeps assignment of ether ‘chunks’ to nodes quick. If the network is reaching capacity, then node operators need less RPL to join as the network needs more node deposits to be matched up with regular users deposits. If the network is maxed out and needs node operators to join quickly, it even drops to 0 for the first one to make a deposit.
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.
