Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

Achain is a public blockchain platform that enables developers of all levels to issue tokens and create smart contracts, decentralized applications, and blockchain systems. Achain is committed to building a global blockchain network for information exchange and value transactions. Unlike Bitcoin or Ethereum, Achain utilizes a modified version of DPoS — RDPoS (Result-delegated Proof of Stake) to establish node consensus. Shortly, DPoS suggests that all coin holders vote for the validator nodes that will produce the next blocks. On the project website, only info about CEO Tony Cui is listed. Cui has a few significant accomplishments, including winning the Future Star award from the Zhongguancun Alliance and being listed in the 30 under 30 on CYZONE, a famous venture capital magazine. On LinkedIn, 51 people are listed as employees at Achain. Most of the team is based in Beijing. Achain also has a few key industry partners. It has even co-organized a “Blockchain Technology Open Course” with Tsinghua University, which is widely recognized as one of the world’s top universities. The roadmap for Achain development is fairly detailed. However, most goals listed are development-oriented rather than marketing or design. Still, it’s important to note that focusing on making the protocol interoperable and building a technology that is more accessible to mainstream adoption could also be considered a marketing-oriented part of this project. There are three major phases with projected completion dates listed. These include Singularity (completed Q1), Galaxy (ongoing), and Cosmos (complete at the end of Q4). One thing to note is that dates for these phases are not consistent between the homepage and the whitepaper. This could be simply due to a scenario in which phase names remain the same while new goals and timeline dates within those phases continue to change. In January 2019, the project will update the website to reflect roadmap goals for the new year. Looking at the current landscape of blockchain projects, Achain certainly offers the possibility of much-needed technical innovations. The ability to easily create an Achain fork, as well as, the protocol’s unique RDPoS consensus algorithm make this a promising project. It will be interesting to see how Achain builds upon its accomplishments, and how the project team continues to develop a long-term strategy for improving the protocol’s technical capabilities and increasing participation in its ecosystem.
