The ArcBlock project was created to create the first Blockchain ecosystem in the world. Develop and develop decentralized applications (DApp) according to objectives. ArcBlock, one of the ICO projects emerging in early 2018. Just launched on 3/1/2018, ArcBlock has quickly attracted the attention of technology as well as investors. ArcBlock brings great technological advancements that will open the third generation of blockchain applications. Arcblock work by bridging the gap between different blockchains and their respective ecosystems has not been easy. There are some solutions which attempt to solve this problem, but it is evident there is plenty of room for competition in this regard. Building an open chain access layer capable of spanning multiple new and existing blockchains is a very interesting business model. Building a new ecosystem meant to connect various chains will not be easy. As of right now, the team has completed its token sale, and the first public release candidate for the Open Chain Access Protocol will be released in Q3. Early 2019 will herald the introduction of more technical features and an Ethereum Blocklet prototype.
Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
