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.
IOST is building an ultra-high TPS blockchain infrastructure to meet the security and scalability needs of a decentralized economy. Led by a team of proven founders and backed by $40 million from world-class investors, including Sequoia and Matrix, IOST aims to be the underlying architecture for the future of online services. The powerful consensus algorithm “Proof-of-Believability” enables next-gen transaction throughput speeds while ensuring nodes stay compliant, using factors including IOST token balance, reputation-based token balance, network contributions and user behaviors. A faster grade Byzantine Fault Tolerance mechanism, microstate blocks, Atomic Commit protocol and a dynamic sharding protocol (Efficient Distributed Sharding) all ensure transactions are safeguarded, consistent and lightning fast while reducing storage, configuration costs and processing power for validators. Anyone is able to participate in every layer of our system, from using services on our blockchain to running a node and validating transactions. Our rules and code are open for all to see and no preconditions will limit participation. IOST aims to fundamentally disrupt previous methods of business by creating a self-operated, trustless network that maximizes network value for all parties. The project places great emphasis on decentralized and secure ways of storing information. It also provides for Dapps and smart contracts, and anyone who is familiar with blockchain technology knows just how integral these two concepts have become. Adhering to the quintessential egalitarian values of blockchain technology, IOST is creating a censorship-resistant and trustless network that is open to all, using blockchain technology to cut out middlemen and maximize network value for all parties. Terrace Wang, Kimmy Zhong, and Ray Xiao, who are extremely brilliant, have co-founded the project. In addition to these original three, the project has 12 employees and 4 advisors. It is also worth noting that Ryan Bubiski, a co-founder of CodeAcademy and a winner of Times Most Influential People award plays a major role in the advisory board of the project. The team has partnered with about sixteen blockchain and cryptocurrency oriented companies such as Sequoia, Nirvana Capital, and DFund. The project, therefore, has strong investors.'
