Blockchain's Major Architectural Components

Here at ScienceSoft, we rely on a flexible multi-layered blockchain architecture and help our customers implement any components required for the seamless functioning of their blockchain solutions.

Sample architecture of a blockchain solution - ScienceSoft


Physical and logical infrastructure serving to connect blockchain nodes, enable communication between them, and propagate transactions and blocks.


Individual devices storing a copy of a shared blockchain ledger and validating transactions according to the network’s consensus algorithm.


On-chain and off-chain storage systems used to store the blockchain ledger with transaction records (including metadata) and smart contract code.

A protocol ensuring all nodes agree on the validity of transactions and the sequence in which they are added to the blockchain.


Hashing and asymmetric encryption mechanisms ensuring the integrity of data stored in the blockchain and safe blockchain transactions.

Integration solutions

APIs, cross-chain bridges, and interoperability protocols enabling communication between blockchain solutions and external systems.


Self-executing agreements with predefined rules (smart contracts, chaincode) serving to automate blockchain transactions when certain conditions are met.


Blockchain-based assets representing a means of payment, ownership of digital or physical assets, utility, governance rights, and other forms of value.

User interfaces

The front-end component (web, mobile, and desktop interfaces) enabling blockchain participants and authorized third parties to interact with the network.

Approaches to Blockchain Network Implementation

A blockchain network is the backbone of any blockchain solution. There are two main approaches to launching a blockchain network, each having its benefits and limitations. The choice of a particular approach depends on each company’s specific needs and requirements for the blockchain project implementation cost and timelines.

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 require much time and high investments.

Forking an existing blockchain protocol and creating a new blockchain

Best for: Companies seeking 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 1.5-2x 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.

How to Implement Blockchain Technology

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.

Step 1.

A feasibility study

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 technology implementation. We work in close collaboration with project stakeholders to get an in-depth understanding of the company’s needs and introduce a list of tangible benefits that blockchain technology can bring. We also deliver a high-level cost breakdown and calculate ROI for implementing blockchain technology.



Step 2.

Building a business case

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.).


Step 3.

Blockchain network conceptualization

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).
  • 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.

Step 4.

Project scoping

1 week

During this stage, ScienceSoft defines:

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


Step 5.

Proof of concept development

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 or test the blockchain potential to meet your specific business and technical expectations.

ScienceSoft’s Blockchain Consultant and Project Manager

Step 6.

Blockchain solution design

1–2 months on average
  • 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 a 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 the required systems (e.g., accounting software, an ecommerce portal, an SCM solution, crypto wallets, etc.).
  • UX and UI design
    • Designing convenient UX for user applications (web, mobile, desktop) that will enable communication with the blockchain.
    • Designing sleek UI and introducing UI mock-ups.


Step 7.

Tech stack selection

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.

Step 8.

Blockchain development

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.


Step 9.

Blockchain solution deployment

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 blockchain testing, integration, and release, sets up the solution’s infrastructure, backup and recovery procedures, and deploys the ready-to-use software 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.

Step 10.

Integration with other systems (if required)

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.



Step 11.

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 blockchain performance, handle operational issues, and modify or add functionality following the changes in business and end user 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.
