How We Developed GOeureka, a Blockchain-Based Platform Shaping the Online Booking Future

How We Developed GOeureka, a Blockchain-based Hotel Booking App

The Story Behind

As far as online travel agencies occupy tourism industry, becoming a competitor to ‘traditional’ business, the last should struggle for preserving the position turning to new means. Huge companies can stand the competition, while smaller ones are suppressed and forced to cooperation with other platforms on non-favorable terms. This leads to profit decrease because clients prefer online ordering to traditional one, while commission rate variants are also limited.

Thus, our client, who has occupied himself with hospitality business quite a long time, decided to change the situation with an easy and convenient solution. He was inspired by the idea of creating an online reservation service compatible with blockchain technologies and tokens to perform transparent direct transactions with minimized fee commission. That was the background preceding GOeureka appearance.

Our Goals

We aimed at big data processing optimization and response time reduction. We worked with four different wholesalers providing services and information. Their own API direct access required time to get response from all participants, to conduct internal data analysis, and then send an answer to user. This time consuming and tiresome procedure needed proper optimization, because we received about 500 requests per second from two different parties. Besides, we aimed at payment system adjustment ensuring smooth blockchain and GO tokens implementation.


To support all the requests we received, we applied big data solution and added forecasting feature. All wholesalers’ data was divided into two parts: ‘static’ and ‘dynamic’. The first one is rarely updated, so we adjusted update time to peak loads, while ‘dynamic’ category is updated immediately without any delays. Such solution made reduction of request time from 70 seconds to 4.6 real.

Project’s database consists of 400 thousand places, accompanied by additional info, like photo/video galleries, accommodations, facilities, etc.

We implemented price forecasting function based on big data, history of price changes, and relevant price multiplied by coefficient. Such an accurate process resulted in 95% of forecast overlap. The final figures were adjusted during reservation process itself.

Micro-services implementation allowed organizing clearly systematized load control able to serve 2-3 million customers.

Profound search system ensures required QPS showcases and highly customized results.

Our platform allowed hosts being directly involved into process. They can work with clients without third-parties and perform room management or reservation on their websites through the system itself. HMR system is responsible for making this process easy and pleasant.

Technological Stack & Team Composition

Technological Stack & Team Composition

To roll out both mobile and web versions we implemented various strategies, concerning different project aspects. To ensure seamless performance we introduced such backend technologies as Node.js, MongoDB, Elasticsearch, Redis. React was implemented to make intuitive interface and create hotel booking app for smartphones. Cloud technologies are accomplished with Amazon Web Services, while Blockchain stability is supported by Ethereum and Solidity.
