TopDevelopers updated the list of top blockchain development companies for 2023, and Serokell is again among the leaders.

Serokell listed among Top Blockchain Developers 2023

Serokell has been included in [the 2023 list of top blockchain development companies by TopDevelopers](https://www.topdevelopers.co/directory/blockchain-developers-in-usa). 

TopDevelopers is a platform that helps businesses identify a reliable software development partner by providing a directory of IT firms. The listing is thoroughly curated based on extensive research and analysis of industry-specific parameters.

One of the most important criteria for evaluation is the IT company's capacity to deliver quality software. TopDevelopers focuses on the firm's web and app design and development processes and the time required to build and provide the solution. The company's proficiency in mobile app development across various platforms, including Android, iPhone, iPad, wearables, and the web, is also considered.

[TopDevelopers](https://www.topdevelopers.co) employs four key metrics to assess reliability: market presence, market penetration, experience, and social media mentions and reviews.

Another criterion is customer feedback, which provides a comprehensive picture of the quality of services offered by the company. 

Serokell is proud to be recognized among the best blockchain development companies. Our commitment to delivering top-notch and secured services to our clients is the cornerstone of our business. We prioritize quality and safety of customer assets above all. Moving forward, we remain dedicated to investing in cutting-edge technology to maintain our position as a leader in the field of fintech development.

How to Win at Web Summit

How to survive and accomplish your goals in large conferences like Web Summit? Roman Alterman gives 6 tips from his experience at Web Summit 2019 and a multitude of other conferences.

_Web Summit is huge. According to official statistics, in 2019 it was attended by 70 469 people. It is an experience of its own kind._

_I’ll describe. Just after entering the first out of five pavilions you are shocked by the multitude of booths and visitors—you look from side to side and think what the strategy should be: should you visit enormous booths of IT-giants like Microsoft or SAP or is it better to start by covering tons of startups all around the area? At the end of the article, I hope you’ll know what to do._
## 6 tips to succeed at your next Web Summit

On November 2-5, the CEO, COO and CBDO of Serokell visited [Web Summit 2019](https://websummit.com/). The event was full of smart people, bright ideas and brilliant innovations. For us as a team, it was a wonderful experience and I would love to share my thoughts about it in a way that’s helpful for first time visitors. 
 
Therefore, I will list a couple of points which can be useful if you are considering taking part in Web Summit or a large global tech conference like it. Let’s go!  


### 1. Know your goal

Before coming to the conference you should spend enough time on preparation to feel confident during the event. 

![Can you feel the confidence?](/files/80/806nfh2x.20191107_175159.jpg)

Remember, everything is possible here. Before coming, you should formulate your precise goal for this week and work in its direction. There are many opportunities: getting new clients, raising funds, searching for outsourcing services, headhunting and testing your hypotheses about the market and its participants.  You could spend all week just working on one thing from this list, and if you are well prepared, the probability of achieving your initial goal becomes very high. 

### 2. Know who participates

The important thing to mention is that Web Summit is more for CEOs and business development executives. As a result, don't count on a high level of technical talks there—it's more about business.

![A look inside Web Summit 2019](/files/au/aukiaf05.20191105_173512.jpg)

Regarding the booths, there are several types of them. Startups have the smallest ones and you can find a huge amount of them in each pavilion according to their industry: FinTech, HealthCare, Social, Security and lots of other fields are amongst the options. 

Besides startups, there are bigger booths for sustainable businesses like JetBrains and different infrastructures like accelerators, hiring aggregators, VCs and even countries. Huge zones are for industry giants like Booking.com, Lenovo, Amazon, Siemens, Porsche, SAP, and dozens of other market leaders. If you are attending for business purposes, there is probably no point to spend much time near the biggest booths. Representatives there usually don’t have the power to make any decisions, they just present their products.  

A very important thing: booths are only the tip of the WebSummit iceberg, thousands of interesting people and projects come in as attendees. The best way to reach them out is through preliminary search and the event-specific app.

### 3. Schedule in advance


Therefore, you should schedule meetings and find interesting opportunities in advance.  
 
Go through the endless list of participants on the Summit website, get in touch with proper ones and arrange a cup of coffee before coming to Lisbon. That way, you will be able to spend all 3 days efficiently.

### 4. Use the Web Summit app

Don’t underestimate the application, it is an instrument that brings you a lot of opportunities. It is key to becoming a part of a huge social network. It’s simple.  
 
1. Fill in your profile and become visible to other participants. 

2. After that, find any person who is interesting to you, propose him a meeting and schedule it right inside the application using the internal calendar.

What is more, you can form your own schedule by choosing interesting speeches and presentations and combining them with your meetings. The application will always notify you about the upcoming activity linking it with the Summit map. You can even use it before and after the event to get in touch with anyone you did not have time to catch in Lisbon or just stay connected to a big base of potential partners.

![Form your own schedule by combining both speeches and business meetings](/files/kk/kk9jijxs.20191106_163318.jpg)

All participants have a [QR code](https://www.adobe.com/express/feature/image/qr-code-generator) on their badge. After talking to anybody, just scan his QR with an app and send him a “Hi!”— that would help you to keep in touch. Probably, this is the first event that is free of business cards. Forget about carrying kilos of carton and remembering who’s card it actually is: just scan the badge and continue the negotiations in the application chat.

### 5. Feel the rhythm of the Night Summit 

After a day in the fields, Night Summit begins. Every evening all participants go to the best party locations. Streets are closed, with access only for people with WS badges. It’s an enormous networking event under the dark sky and an awesome opportunity to build business relations informally. We have to admit that it is not so easy—the amount of people is very large, and as a result, everybody is grouping and finding a lead becomes quite tough. To succeed, you need to be a networking shark. 
 
Besides the official Night Summit, there are lots of side events sponsored by different companies and projects. In our opinion, most of them are not worth visiting—descriptions are brilliant, locations are interesting, but, frankly speaking, it is very hard to compete with the official one. Visiting a side event could be efficient only if you have a specific interest in it. If not, we believe that spending time at Night Summit is much more reasonable. 


### 6. Be prepared for the crowd

The only negative thing I can mention is also the best one: the number of visitors. 

![Visitors at the event](/files/o4/o4j2scdc.20191106_124824.jpg)

Be ready to spend a lot of time in lines of differing shape and size: to enter the location, drop off your bag, get a meal or get inside the stage zone. However, there are a few life hacks which can make life easier.  
 
* Don’t forget to go through the registration at the airport just after landing in Lisbon. There is a huge tent with volunteers which can help you out with that. Registering directly at Summit could become a disaster—on the first day you may spend an hour or more in the line.

* Use the “Fast Track” application for choosing and paying for your meal and just pick up your order in a specified place. 

* Come earlier or later than 10-10:30 AM or lose your priceless time waiting in line at the entrance.

## Conclusion

Web Summit is not a regular IT conference. It’s a huge celebration. It’s a time of gathering for the IT world. Everything is possible here. It’s an awesome opportunity to open your mind, find out how different countries and cultures have their own individual ideas, approaches and views. It’s a good opportunity to invest or find investments, a perfect way to build up your international network. 

Keep in mind that this time can be spent efficiently only in synergy with good preparation and sufficient experience. If you are counting on this event as an instrument for business development, don’t choose it as your first conference—train on smaller ones. Literally, train,  because all the other events seem to be just training once you get to Web Summit.

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.
