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.'
Wanchain seeks to link the present to the future, through the exploration and implementation of blockchain technology. Wanchain aims to build a distributed “bank”. Just as traditional banks are the infrastructure of the current financial framework, Wanchain seeks to build a new, distributed infrastructure of digital assets to form an improved, modern framework - an ambitious goal indeed. Wanchain connects and exchanges value between different blockchain ledgers in a distributed manner. It uses the latest cryptographic theories to build a non-proprietary cross-chain protocol and a distributed ledger that records both cross-chain and intra-chain transactions. Any blockchain network, whether a public, private or consortium chain, can integrate with Wanchain to establish connections between different ledgers and perform low cost inter-ledger asset transfers. The Wanchain ledger supports not only smart contracts, but also token exchange privacy protection. With Wanchain, any institution or individual can set up their own virtual teller window in the “bank” and provide services such as loan origination, asset exchanges, credit payments and transaction settlements based on digital assets. Under the guarantee of “banks” based on the blockchain infrastructure, more people can participate in financial services based on digital assets. To describe it more accurately, Wanchain is a distributed super-financial market based on blockchain. Wanchain uses the Locked Account Generation Scheme to secure funds and keys when there are multiple parties involved. Based on Shamir’s Secret Sharing Scheme, it effectively breaks up a key into shares and distributes it to all included participants. The Storemen are responsible for maintaining and managing the appropriate key shares of the locked accounts for transactions. This method of key share distribution has a few benefits. Because Wanchain generates locked accounts through multi-party computations, there’s increased decentralization. And there’s more stability because you don’t need every key share to produce a signature for a locked account. If some of the Validators are offline, transactions can still be executed with a minimum number of shares. Finally, any transaction with a locked account is done via the original chain. This means that any chain can easily integrate and interact with Wanchain without the need for new transaction types or validators. The Wanchain Foundation is a non-profit organization primarily operating out of Singapore but also has a significant presence in Austin, TX. Wanchain was founded by Jack Lu, a respected player in the blockchain space. Before his current role, Lu co-founded Factom and started Wanglu Tech, a blockchain application development company. Wanglu Tech has been a primary contributor to the open-source Wanchain project. Dustin Byington serves as the Wanchain President. Byington is a blockchain veteran having founded Bitcoin College in 2014 as well as co-founding Tendermint, a software mechanism to securely and consistently replicate applications across machines. Byington also co-founded Satoshi Talent, a platform to connect blockchain entrepreneurs with developers. WAN tokens were initially distributed as ERC-20 tokens to ICO participants, but it’s now possible to exchange these for tokens on the Wanchain mainnet or buy them directly. It’s a common misconception that WAN is an ERC-20 coin. Wanchain is a pioneering and potentially disruptive project with its sights set on becoming a super financial market of the world. Although achieving its lofty goal(s) is going to require a lot more work, Wanchain is further along its roadmap than some projects. But there’s still a good bit of “in theory” going on here. As Wanchain is addressing the whole financial market, it has a number of competitors. Most notably Fusion, Pantos, Ark, and Qash; some may even consider big players the likes of Ripple, Stellar and Ethereum competitors. On the positive side, Wanchain has strong fundamentals, they’ve got a functional mainnet, the vitality of their use case is indisputable, the huge interest in their ICO showed a powerful vein of investor confidence, and the team has a track record of success.
