Problem # 1 – The shortage of blockchain specialists

The number of available blockchain specialists is incredibly low compared to other technologies. For instance, on Linkedin, there are 630 Blockchain developers, which is a minuscule number compared to 211,762 results for Java developers.

Blockchain experts are thin on the ground for the technology is new and there are no plug-and-play solutions, especially if your business calls for building a private or a consortium blockchain. What’s more, blockchain technology spans across many areas of application, from peer-to-peer financial transactions and corporate data management to improving government transparency and voting.

The scarcity of blockchain specialists has its implication for the global market and individual companies. According to the survey conducted by Synechron and TABB Group, about 40% of firms do not have enough qualified engineers to implement blockchain solutions. The shortage of available talent for blockchain was raised as a critical topic at the DTCC’s Fintech Symposium, held at the Grand Hyatt in New York City on March 1, 2017.

Given the lack of supply, companies are now competing with each other for the blockchain talent, and the competition is fierce. According to, there are 424 blockchain job postings. Of those 51 are listed for IBM, 24 for Ethereum startup ConsenSys and 22 – for SAP, one of the world’s largest enterprise software vendors.

Outsourcing blockchain development – Where to find the experts?

To solve the problem, companies often consider outsourcing blockchain development to Eastern Europe as a reliable outsourcing destination with solid IT expertise and extensive talent pool. However, choosing the IT outsourcing country and a specific company to outsource your blockchain development to may be challenging. You can find blockchain expertise in such countries as Ukraine, Bulgaria, Belarus, and Poland.

There is a wide range of blockchain conferences, events, and hackathons held in Ukraine: Blockchain and Bitcoin conference, Blockchain Conference Kyiv, Blockchain Business Forum, Microsoft Blockchain Intensive, to name but the few. In 2015 five technical universities of Kharkiv, Ukraine, have partnered with Distributed Lab to add blockchain courses to their curriculum.

Such IT companies as Distributed Lab and Ambisafe have teams of Ukrainian developers who implement blockchain solutions. Ukrainian developers have delivered such blockchain-based solutions as INFRA (regulates communication between parties without a common ledger), E-VOX (simplifies the voting process by using smart contracts), GURTOM FOUNDATION (facilitates service exchange), TREE TAG (A traceability system designed for smartphones aiming to help industry and governments remove illegally logged tropical hardwood from the global supply chain). Such Ukrainian companies as N-iX, Romexsoft, and Eleks offer blockchain development expertise.
