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.
Vertcoin is a decentralized currency owned by its users, a P2P cryptocurrency in the same vein as Bitcoin and Litecoin. Like its two predecessors, Vertcoin exists solely as a currency, and it uses proof of work to reach distributed consensus. Unlike its two predecessors, however, Vertcoin is dedicated to keeping its mining functions decentralized, so contrary to most PoW coins, it’s ASIC resistant. Branding their project as “The people’s coin,” Vertcoin’s team believes that ASIC resistance invites a fairer, more democratized currency for both users and miners. Along these lines, Vertcoin sports its very own 1-click miner, a program meant to make mining more accessible to the general public. The motivation of Vertcoin was the fact that Scrypt-based ASIC mining chip that is used to mine Scrypt derivative coins such as Litecoin and Dogecoin is entering the mass market. That coupled with strong mining pool causes the strength of a cryptocoin to drop as it becomes easier for a specific party to pull a 51% attack and even monopolize the network. Scrypt-Adaptive-Nfactor was created to address that issue. Vertcoin is zero premined and as of the current design, only 84 million coins would ever be created. Vertcoin is said to be the next generation of coins due to its unique hashing algorithm. There may be more altcoins created based on this hashing algorithm in order to defend their network against ASIC miners. Like most all pre-2015 coins, Vertcoin took a deathblow after Mt. Gox was hacked, throwing the entire market into a crypto winter. As such, it was relatively inactive until the revival last spring/summer. Since then, it has had steady climb up the market cap ladder. A 2014 International Business Times article mentions Vertcoin as a potential Bitcoin successor. The article notes that it ''hopes to offer an alternative. By taking the foundations of Bitcoin and making some adjustments, Vertcoin punishes miners who use powerful machines and work together in 'pools' to monopolise the mining market.'' On July 1, 2014, Vertcoin released a wallet supporting Stealth Address transactions. On December 13, 2014 (block 208301), Vertcoin forked from Scrypt-Adaptive-N proof-of-work function to Lyra2RE as a proactive defense against emerging Scrypt-Adaptive-N capable ASICs. On August 10, 2015 (block 347000), Vertcoin forked from Lyra2RE to Lyra2REv2 because a botnet was controlling more than 50% of the hashing power of Vertcoin network. On May 7, 2017, Segregated Witness (SegWit) feature was activated in the main network. SegWit update includes the Lightning Network technology that was also demonstrated in action during the same day.'
