  • A stock trader StockBaller recently published a review of the CLCI (Clic Technology) company and its partner Opporty.
  • The accomplishments and merits of Opporty and CLCI were glossed over and downplayed, unfairly misleading readers.
  • On behalf of Opporty, I would like to clarify some nuances and add important facts to StockBaller’s report, to present a more holistic and accurate picture.

This article was published a few days ago on the website seekingalpha.com. It provides some weighty conclusions but does not present the full picture of how the Opporty team works and its many achievements. The article characterized our company in a negative light, and I would like to correct this injustice in my expanded analysis.

Media activity

Opporty’s media activity on Twitter, our blog, and the GitHub repository for Opporty Plasma Cash may seem slow-paced because we publish only the most important news there. Our team believes it is better to write fewer quality posts than to write frequently about nothing of significance. When you visit these resources, you will always find concise and meaningful reports about our accomplishments. You will find no fluff or irrelevant information.

Also, it is important to take other social media platforms into account, Telegram in particular, where Opporty has been actively and regularly communicating with the Blockchain community for the entire period mentioned in the libelous article.

Opporty has been mentioned 200+ times in media and news platforms of various sizes, including some of the largest. A publication for Mars Finance about blockchain Plasma Cash-based implementations in international trade, made by the company’s founder Sergey Grybniak, has become one of the best publications in the entire series. Its key ideas coincide with concepts in the book “Can Blockchain revolutionize International trade?” by Emmanuelle Ganne, which was later published by the World Trade Organization. The article’s translation for Hacker Noon is available here.

Opporty has a Plasma Cash implementation

In general, the current state of blockchain technology is far from complete. The industry has no established and confirmed standards that define the “readiness” of blockchain implementations. That is why all developers, including The Big Four, often use a “work in progress” disclaimer.

When talking about Plasma (and Plasma Cash), we always keep in mind private side chains for processing transactions, with “exits” to the Ethereum root chain.

It would be wrong to judge our project based on the first release of a partially working Plasma Cash prototype. It was able to process transactions but still lacked many functions. At that time, it was the first working Plasma Cash implementation on GitHub.

It should be noted that, at the time, we found only one repository with Plasma Cash apart from our own. But we were not able to launch it, and the company developer/owner of the repository has not made any statements about its ability to process transactions.

At the time of our first release, the product was in its infant stages, since we made this release less than two months after the Plasma Cash framework was proposed by Vitalik Buterin, the founder of Ethereum.

Later, we added significant improvements to this release, including but not limited to scalability, privacy (check out details here and here), and a DPOS consensus algorithm. At the time of our latest release in December 2018, we already had private side chains with a separate consensus algorithm and “exits” to the Ethereum root chain. In other words, our revised solution was in a ready-to-use use state for particular use cases.

We have not updated our GitHub account since then because we were improving and refactoring the existing code and preparing to release the new solution for private transactions in the Ethereum network. The development of our product goes beyond our collaboration with CLCI and is scheduled to be announced shortly.

To sum it up

StockBaller has expressed his opinion, and he has the right to be heard. In the same way, the Opporty team has the right to add important details and show all facets of the issue. Together we should be able to paint a comprehensive picture reflecting the truth. The representatives of Opporty are always grateful for objective criticism, but we cannot stay silent when essential details are omitted and our achievements downplayed.
