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.
MonaCoin is an open source digital currency and a peer-to-peer (p2p) payment network. Dubbed by its creators as “the first Japanese cryptocurrency,” the coin has become somewhat of Japan’s national alternative to Bitcoin or Litecoin. Like its predecessors, the coin was created purely to serve as P2P electronic cash, a decentralized digital currency aimed at Japanese citizens. There are a few key differences that set it apart from the coins that came before it, and this guide is dedicated to drawing out these differences. Conceived in December of 2013, Monacoin was officially born on January 1st, 2014 with no premine. A Bitcoin Talk Forum on the same date details the coin’s launch and its specifications. A soft fork was executed at block 937440 to implement Segwit, a move made to keep it in line with Bitcoin, Litecoin, Vertcoin, and other payment-focused cryptocurrencies. In addition, the Monacoin team has reportedly implemented the Lightning Network for their coin. Speaking of soft forks, Monacoin is actually a hard fork of Litecoin, something we’ll take into account further as we look into its specs below. Monacoin was originally founded by the pseudonymous Mr. Wantanabe, no doubt in homage to Bitcoin’s Satoshi Nakamoto. Besides this pen name, the rest of the coin’s team is completely anonymous, so there’s nothing to report on here. In addition, the project has no visible roadmap on its site or anywhere else online. The team does seem to stay on top of updates and upgrades, however, as the Segwit and Lyra2REv2 updates and Lightning Network implementation suggest. It is popular in Japan where it was developed. It Uses Lyra2REv2 and Dark Gravity Wave v3 algorithm to ensure fairer mining opportunities, success rate and difficult levels of mining process respectively. Monacoin is the first cryptocurrency from Japan. It has received wide support and success in the country and is not crossing the national boundary to try and become a global phenomenon. While that is not going to happen in the next year or two, it does have the making of a good crypto token. It is steadily improving its service and has constantly strived to give its users the best possible experience. When Scrypt compliant ASIC miners appeared they switched to Lyra2REv2 to ensure the mining MONA remains a fair battle between miners from around the world. The instance of a Japanese national using Monacoin to buy land made news in the country and beyond, spreading the popularity of the coin.
