Blockchain Implementation: Summary

Blockchain implementation aims to help companies leverage the blockchain-based solutions that introduce decentralized data storage and processing, guarantee data immutability and integrity, and offer effective workflow automation. Blockchain software ensures full transparency, topflight security, and fast processing of data and transactions.

Key project steps: A feasibility study, business case creation, blockchain conceptualization, project scoping, PoC development (optionally), blockchain solution design, tech stack selection, development, deployment, integration, after-launch support and evolution.

Team: a project manager, a business analyst, a blockchain architect, a blockchain developer, a UX/UI designer, a front-end developer, a back-end developer, a DevOps engineer, a QA engineer.

Timelines: 4–12+ months, depending on the solution complexity.

Cost: Depending on the chosen approach to blockchain network implementation and other cost factors.

Average payback period: 12–18 months for a custom blockchain.

ScienceSoft can cover the end-to-end implementation of all required blockchain components – from the blockchain network to decentralized applications (dApps), user-facing apps, and business logic, e.g., smart contracts. We ensure prompt rollout and high quality of the blockchain solution due to the proven tech skills and multi-industry expertise of our team.

Types of Blockchain Solutions

Visit ScienceSoft's dedicated pages to learn about the capabilities, benefits, and cost factors of blockchain-based solutions:

Blockchain networks

Secure and scalable permission-based or permissionless decentralized ecosystems with minimized downtime.

Blockchain-based transaction platforms

Peer-to-peer platforms with no single point of failure for transparent, fast, and safe multi-party transactions.

Blockchain-based assets

Programmable crypto assets built on blockchain that may represent a digital form of money, tradeable assets, utilities, governance rights, and more.

Approaches to Blockchain Network Implementation

A blockchain network is the core of any blockchain solution. There are two main approaches to implementing a blockchain network, each having its benefits and limitations. The choice of a particular approach depends on a company’s specific business needs and requirements to the implementation time and budget.

Building a custom blockchain from scratch

Best for: Blockchain startups and fintech companies that want to come up with a unique product or service.

A blockchain network is designed and developed from scratch. Other architecture components are then built on it to get a required blockchain solution.

Benefits: The ability to implement a blockchain solution fully tailored to your business needs.

Cautions: Custom design and development requires much time and high investments.

Forking an existing blockchain protocol and creating a new blockchain

Best for: Companies that want to implement blockchain for corporate use.

A blockchain network is designed based on the open-source code of a well-established blockchain protocol (e.g., Ethereum, Hyperledger Fabric). The code is modified according to your requirements to introduce a new blockchain network with different features and rules to operate independently and host your blockchain apps.

Benefits: Significantly reduced cost of blockchain development and x1.5-2 faster blockchain launch, compared to a custom approach.

Cautions: The risk of choosing an inappropriate blockchain protocol to fork.

NB! Suppose you’re looking to implement a standalone decentralized application or a crypto asset rather than a fully-functional blockchain. In this case you may consider developing and deploying them on an open-source blockchain platform (e.g., Ethereum, Tezos, EOS). This option enables a fast and cost-effective launch of the required app or asset. However, the underlying blockchain architecture, consensus mechanism, and recordkeeping rules cannot be customized to your needs.

Blockchain Implementation Plan

The duration and approach to the blockchain solution design and implementation depend on the specifics and scale of operations the solution should cover. Below are described typical steps we at ScienceSoft take to implement a blockchain.

A feasibility study

Duration: 2–4 weeks

Although general and use-case-specific benefits of blockchain look persuasive, blockchain viability requires assessment for each business situation. ScienceSoft’s consultants help analyze the economic feasibility of blockchain implementation. We work in close collaboration with project stakeholders to get an in-depth understanding of the company’s blockchain needs and introduce a list of tangible benefits that the blockchain technology can bring. We also conduct a thorough analysis to present a high-level implementation costs breakdown and ROI calculations.



Building a business case

Duration: 1 week

To create a reliable framework for planning and managing your blockchain initiative, we do the following:

  • Elicit and document functional and non-functional requirements for the blockchain solution.
  • Identify and resolve conflicting requirements.
  • Analyze potential risks, including related to regulatory compliance (e.g., with AML/CFT and KYC, SEC, FINRA, GDPR, ISO 27001/27002, HIPAA, etc.).


Blockchain network conceptualization

Duration: 1 week

This stage involves decision-making on:

  • A proper blockchain network type (private, public, or hybrid).
  • A best-fitting consensus mechanism (e.g., Proof-of-Stake, Proof-of-Authority, Byzantine Fault Tolerance).
  • An optimal approach to implementing a blockchain network (building a blockchain from scratch or forking an existing blockchain protocol).

If your company opts for the forking approach, ScienceSoft can conduct a comparative analysis of the market-available blockchain protocols to help you choose the one that meets your blockchain needs best and requires the least modification efforts.

Project scoping

Duration: 1 week

During this stage, ScienceSoft defines:

  • Objectives, milestones, and KPIs for the project.
  • Project deliverables.
  • Project duration, schedule, and a time-framed budget.
  • Project-associated risks and the ways to mitigate them.


Proof of concept development

Duration: 1–2 months on average.


We recommend opting for a PoC and/or blockchain prototypes in case you need to check the viability of an innovative blockchain solution in real life or test the blockchain potential to meet your specific business and technical expectations.

  • Feature road-mapping
    • Preparing a detailed feature list for the blockchain solution, including cybersecurity features.
    • Feature prioritization based on the cost-benefit analysis.
  • Architecture design. Designing secure, scalable, high-performing architecture for the blockchain solution components and their interactions.
  • Integrations planning
    • Suggesting cross-chain interoperability patterns for the blockchain solution.
    • Preparing an integration plan with external systems (e.g., accounting software, an ecommerce portal, a SCM solution, etc.).
  • UX and UI design
    • Designing UX for user applications (web, mobile, desktop) that will enable communication with the blockchain.
    • Designing UI of the apps and introducing UI mock-ups.


Tech stack selection

Duration: 2–4 weeks on average

At this stage, ScienceSoft assists in:

  • Defining techs and tools required for the blockchain solution implementation.
  • Comparing different techs and tools in the context of documented business requirements.
  • Selecting the optimal techs and tools.

When forming a tech stack for blockchain implementation, we at ScienceSoft always consider our clients’ priorities (minimized cost/time/risks of the solution implementation, etc.). To optimize project time and costs, we rely on ready-made components (smart contract building blocks, prebuilt UI components, open-source APIs, OOTB deployment scripts, etc.) where possible.

ScienceSoft’s Head of PMO

Blockchain development

Duration: 2–7+ months, depending on the solution’s complexity.

The development of a blockchain-based solution with ScienceSoft usually has the following stages:

  • Depending on the chosen approach to blockchain implementation:
    • Developing a blockchain network from scratch.
    • Modifying the code of an existing blockchain protocol (e.g., Ethereum, EOSIO, Solana, Polygon, Bitcoin) to build a new blockchain network.
  • Smart contracts development to introduce business process automation.
  • Developing on-chain and off-chain oracles to enable data exchange between smart contracts and external data sources.
  • Developing user-facing applications (web, mobile, desktop) to interact with the blockchain solution.
  • Developing the back end of the blockchain solution, including APIs and cross-chain interoperability protocols, to enable data aggregation, processing, and storage.
  • QA activities in parallel with development.


Blockchain solution deployment

Duration: 1–2 weeks (depending on the number of the blockchain solution user groups, the duration can be longer).

ScienceSoft’s team configures CI/CD pipelines to automate the blockchain solution testing in the test environment, setting up the solution’s infrastructure, backup and recovery procedures, and deployment of the ready-to-use solution to the production environment.

An enterprise blockchain should be first deployed to one of the target user groups or facilities for a pilot run. This way you’ll be able to handle possible issues and change requests before rolling out the solution enterprise-wide and avoid costly adjustments.

ScienceSoft’s Head of Web Development

Integration with other systems (if required)

Duration: 1–8 weeks (depending on the integration complexity)

At this stage, ScienceSoft’s team implements and tests integrations with the required systems, including those built on other blockchains, to enhance the solution’s value for end users.



Support and evolution

Duration: continuous


ScienceSoft offers a range of services to ensure the smooth operation of the blockchain solution in the long run. Particularly, our team can monitor the blockchain performance, handles operational issues, and modifies or adds functionality according to a client’s evolving needs.

Although blockchain provides advanced data security, it can be susceptible to certain types of cyberthreats, such as routing attacks, phishing attacks, and code exploitation. I recommend our customers to implement additional cybersecurity mechanisms (e.g., intelligent fraud detection algorithms, authorization controls for APIs) to ensure the protection of the blockchain solution and the data it stores, and perform regular network vulnerability scanning.
