Serokell at NixCon 2020

On October 16-18, we participated in NixCon 2020. 

NixCon is an annual conference for contributors and users of [Nix](https://serokell.io/blog/what-is-nix) and NixOS. 

It’s an event we keep participating in every year, [including the previous one](https://serokell.io/blog/serokell-nixcon2019). This year, due to the COVID crisis, it was done remotely. 

One of our employees, Alexander Bantyev, participated with a talk on Nix flakes in production, a thing we have been working for some time now. 

If you’re interested, here’s the talk. You can also see all the other talks of the event on their YouTube channel.

Serokell on the List of the Best Software Developers 2022

TopDevelopers has included Serokell in the [2022 listing of the best software development companies](https://www.topdevelopers.co/directory/software-development-companies).

TopDevelopers is a directory of IT firms designed to help companies find a trusted technical partner. The listing is based on thorough research and in-depth analysis of numerous industry-specific parameters.

These metrics include the ability to deliver, reliability, quality of work, customer feedback, and certifications and awards.

The ability to deliver high-quality applications is one of the most critical evaluation criteria. TopDevelopers pays particular attention to the IT company's web and app design and development processes, and the time it takes to build and deliver the app or service. The company's expertise in mobile app development for Android, iPhone, iPad, wearables, and the web is also carefully considered when evaluating the ability to deliver.

For assessing reliability, TopDevelopers uses four key metrics: market presence, market penetration, experience, and social media following. 

To evaluate the quality of work, TopDevelopers carefully studies the company's portfolio, taking into consideration the complexity of the projects, the ability to meet the guidelines set by the client, accomplishments, and innovative solutions. 

Customer feedback is another crucial evaluation criterion that completes the picture of the service offered by the company. TopDevelopers divides customer reviews into different categories based on the technological level of the company before evaluating them according to general metrics.

TopDevelopers pays close attention to the certifications and awards the company has received for its work. These confirm that the software developer consistently provides high-quality services and maintains high working standards recognized by the professional community.

Serokell is honored and happy to be on the TopDevelopers list for the best software development companies. As always, we are committed to providing our clients with high-quality, personalized research-based services while continually improving our customers' experience with our company.

Serokell Recognized as a Top Bockchain, Smart Contract and NLP Developer

Serokell Takes First Place at TON Contest

Our team beat the competition at TON smart contracts contest with top-notch computer science skills, hard work, and Haskell. Read this post for more details.

On November 15, 2019, Telegram announced the winning submissions for their [TON smart contract contest](https://t.me/contest/103). In the contest, participants were asked to create at least one of the smart contracts from a list of five contracts that was provided.

The first place and $28,750 was taken by [this submission](https://contest.com/blockchain/entry404). If you have been following our blog, it might look familiar.

## Serokell takes the largest prize at TON smart contracts contest 

Our team of five of the Serokell’s finest submitted two smart contracts for Telegram Open Network:

1. [Asynchronous payment channel](https://github.com/serokell/ton-paychan) in FunC with a CLI in Fift. Asynchronous payment channel enables participants to send payments to each other off-chain while still guaranteeing the final settlement.  
2. [Multisignature wallet](https://github.com/serokell/fift-asm-dsl) with TVM assembler embedded in Haskell. Multisignature wallet enables the funds on an address to be accessed only if multiple signatures by multiple private keys are provided.

You can read more about the technical details of the solutions in [this blog post](https://serokell.io/blog/ton-blockchain-competition) by one of the participants, our CTO Kirill Elagin. 


## Hard work pays off 

The participants from Serokell’s side were: our CTO, one of our team-leads, and three experienced blockchain developers well-versed with Haskell and other functional programming languages. 

![Our team for the TON contest. Everybody did amazing, thanks!](/files/4k/4kjy381m.participants3.jpg)

All in all, we tracked 380 hours on this project including meetings, getting to know documentation, and development. 


##  Hackathon that breeds innovation

There were a lot of [impressive submissions](https://contest.com/blockchain) from other teams as well. TON is one of the more promising projects in the blockchain space, and it is wonderful to see many great minds working on it already. 

At the end, we would like to thank Telegram for the experience. In the words of Kirill: 

> This spirit of a hackathon, close teamwork, the need to quickly dive into a new technology – I think all engineers know how exciting it is.
