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.
Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
