Bitcoin Gold hopes to change the paradigm around mining on the Bitcoin blockchain. According to the founders, the Bitcoin blockchain has become too centralized. Large companies with huge banks of mining computers now mine the vast majority of Bitcoin. For the founders of Bitcoin Gold, having large companies control the Bitcoin network defeats the purpose of a decentralized ledger and peer-to-peer currencies. In response, they’ve initialized the Bitcoin Gold project. It’s an alternate fork of the Bitcoin blockchain that implements changes that make mining more equitable. The goal of Bitcoin Gold is to create a network where anyone can become a miner with only basic hardware. As a result, Bitcoin Gold mining would be spread among many miners, instead of a few large companies.There have several features such as decentralization. Bitcoin Gold decentralizes mining by adopting a PoW algorithm, Equihash-BTG, which cannot be run on the specialty equipment used for Bitcoin mining (ASIC miners.) This gives ordinary users a fair opportunity to mine with common GPUs. Besides, there have fair distribution. Hard forking Bitcoin’s blockchain fairly and efficiently distributes 16.5 million BTG immediately to people all over the world who have interest in cryptos. Other methods, such as creating coins with a new genesis block, concentrate ownership within a small group. There also have a replay protection. To ensure the safety of the Bitcoin ecosystem, Bitcoin Gold has implemented full replay protection and unique wallet addresses, essential features that protect users and their coins from several kinds of accidents and malicious threats. Most new mineable cryptocurrencies involve ASIC-resistant hashing algorithms, and it’s becoming something of an industry standard to promote decentralization. In that respect, Bitcoin Gold holds a lot to be excited about. At its core, it’s about transitioning the Bitcoin network to more decentralized mining. However, as we saw above, there’s not much evidence that the current Bitcoin mining system is broken. There have been some small complaints, and it’s not ideal that the network is so centralized. Nevertheless, miners on Bitcoin have a lot to lose if they wield their power too aggressively. There are also new entrants to the Bitcoin mining community that are decentralizing control from a few key ASIC farms. The general consensus from Bitcoin experts is there’s not enough new in Bitcoin Gold to warrant an independent investment. While it certainly doesn’t hurt to hold onto your free BTG that you receive as a result of the fork (if you owned Bitcoin before Oct 24), wait until the dust settles before deciding whether to buy more.'
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.
