What Our Customers Appreciate About ScienceSoft

Owing to ScienceSoft’s expertise in Blockchain-based software development, we chose them as a technology partner for the CoolWallet SDK development project. We were pleased with the outcomes of the project, as well as with the transparent and responsive collaboration from the vendor.


We wanted to build a multi-chain crypto wallet that would let users convert cryptocurrencies without commission. ScienceSoft came up with a go-to architecture, features, and tech stack for our multi-chain wallet and introduced a detailed roadmap for crypto wallet implementation. Besides, they helped us develop a corporate website to represent essential technical information and a white paper for our potential customers and investors.

For our project – building a Bitcoin mobile wallet on Cordova – we needed the assistance of a skilled mobile developer. ScienceSoft promptly provided us with an expert who joined our project team and quickly got up to speed with our Scrum processes. The developer quickly understood the existing code base and proceeded to modify and evolve it according to our requirements. Together, we released our app on time and on budget.

Blockchain Development Steps

The blockchain software development process at ScienceSoft looks as follows:


Discovery stage

If you are implementing blockchain for corporate use, ScienceSoft’s consultants analyze its feasibility for your business needs to ensure it will bring the expected payback. For blockchain startups, we research the competition, suggest the appropriate market niche, and help define a unique selling proposition.




Blockchain software design

We compose an optimal feature set for your blockchain software, decide on the fitting blockchain network type and consensus mechanism, and suggest the most effective approach to development (forking, platform-based development, or building a custom blockchain from scratch). We architect your solution for high scalability, full security, and smooth cross-chain integrations. Our UX/UI designers create a stylish and user-friendly interface for your blockchain app.




Tech stack selection

Our experts select a reliable toolkit for blockchain implementation, including networks, hosting platforms, smart contract frameworks, off-chain storage, and more. When picking a tech stack, we always focus on our client’s priorities for the project: fast development, reduced investments, minimized risks, low app maintenance costs, etc.




PoC delivery (optional)

We build small blockchain software components and sample smart contacts to prove their technical viability, usability, and compatibility with the required systems. The proof of concept’s components can be reused later on in development to speed up delivery.

A well-designed white paper for a blockchain solution helps attract early investments and prevent regulatory issues. If your planned software focuses on token issuance and distribution, we can draw a reader-friendly white paper explaining the solution’s tokenomics and operational principles to all target audiences.

Development and testing

We develop the essential blockchain software components (back end, smart contracts, APIs, oracles, cross-chain bridges, role-specific user interfaces, etc.), set up off-chain and on-chain data storage, and establish connections between the solution parts. Our QA team runs rigorous testing (functional, performance, security, and more) in parallel with development to quickly identify and fix potential issues.




Integration and deployment

We set up a blockchain software infrastructure, configure data backup and recovery procedures, implement robust network protection mechanisms, and establish a DevOps environment to speed up releases. Once your blockchain solution is deployed, we integrate it with the required corporate and third-party systems and set the ready solution live.

A Sample Blockchain Architecture

ScienceSoft understands how confusing and counterintuitive the blockchain concept may look at first glance even for tech-savvy persons. However, when explored from the course of traditional architectural patterns, blockchain appears not that complicated. Below, we share a sample multi-layer blockchain architecture our development experts rely on to help you get a general idea on how blockchain functions.

Sample architecture of a blockchain solution - ScienceSoft

  • Presentation layer enables user interaction with the blockchain network via web and/or mobile applications.
  • Application layer (business logic) provides instructions for transactions defining, invoking, and execution.
  • Distributed computing layer enables transaction e-signing, validation, execution, and recording, comprises data block hashing and auto-updates across nodes’ copies of the shared ledger.
  • Platform layer ensures communication between blockchain and other applications and blockchain-to-blockchain interoperability.
  • Infrastructure layer defines the type of network utilized by the blockchain, participating nodes, virtual and physical storage for the blockchain ecosystem.

Blockchain Software Development and Blockchain App Development – Feel the Difference

While both blockchain software development and blockchain application development involve creating a blockchain-based solution, the former is a much broader field and may cover the latter within the task scope.

Blockchain software development

ScienceSoft’s blockchain software development services encompass the design, implementation, and maintenance of complex blockchain-based systems that perform a wide variety of operations and may comprise a dedicated processing engine, off-chain data storage, and role-specific apps.

Examples: a blockchain system for cross-border payments, blockchain-based food supply chain software.

Blockchain software development requires the knowledge of multiple technology domains and may involve specialized skills, such as blockchain network architecture design and blockchain integration with AI and IoT systems.

Blockchain application development

Blockchain app development is a subset of blockchain software development that focuses on designing and building applications for end users to perform specific tasks like tracking certain transactions and events, making requests or payments.

Examples: a crypto wallet, a blockchain app for insurance claim filing, a blockchain app for inventory control.

ScienceSoft’s blockchain app development services are aimed to create secure and convenient dApps with valuable features and sleek visual style. We pay special attention to UX/UI design and usability testing to ensure seamless user experience with the apps we deliver.
