The Ultimate Guide to Blockchain Solutions Development

Solidity, VyperThe blockchain development process is a technically complicated task requiring many decisions along the way. Should you go for a private or a public blockchain? Which blockchain platform to use? Which blockchain technology to select? Should you build on an existing platform or your own blockchain from scratch?

This guide focuses on creating a blockchain solution with these steps in mind. You will learn whether your business will benefit from blockchain development, go through creation steps, and select a platform, technology, and other project elements.

Understanding the core blockchain principles

To understand what blockchain truly is, how to create blockchain, and whether your company would benefit from blockchain development and consulting , you should grasp the fundamental principles that make blockchain different from other technologies. They are:

• Decentralization: Unlike traditional databases managed by a central authority, blockchain distributes its ledger across a network of computers. This effectively means no single entity has control over the entire network. Decentralization is the reason why blockchain is relatively safe and challenging to manipulate.
• Transparency: Every transaction on the blockchain is recorded and publicly visible to anyone accessing the network. Once a transaction is added to the blockchain, it cannot be altered or deleted.
• The principle of consensus mechanisms: The network nodes must reach a consensus to add a new transaction or block to the blockchain. Popular mechanisms include Proof of Work (used by Bitcoin) and Proof of Stake. These mechanisms validate transactions and protect the network from fraudulent activities.
• Cryptography: Blockchain uses cryptographic techniques to secure transactions. Each block contains a unique hash, and altering any information within the block changes this hash. This creates a linked chain that is extremely difficult to fake.
• Tokenization: Blockchain allows digital tokens to be created, representing assets or rights and being traded over the blockchain. This enables new forms of digital assets and economies. Cryptocurrencies and NFCs are examples of such tokens.

Blockchain benefits: How it transforms businesses

Among the benefits that motivate your company to build your own blockchain are enhanced security against data fraud, increased transparency, and traceability of transactions. By eliminating middlemen and intermediaries, blockchain can also significantly reduce transaction costs.

Overall, blockchain's decentralized structure removes the risk of centralized control and single points of failure, enhancing system resilience and reducing vulnerability to attacks or operational issues.

Is blockchain right for you? The truth is that it can benefit your business in non-obvious ways, even if other businesses in your industry don't often use it. Your business needs blockchain solutions if:

• You are looking to store enterprise-level amounts of data and need a transparent ledger for it.
• You need automated support for vast amounts of data without manual maintenance.
• If you operate directly without a third-party authentication solution.
• If you are not worried about having a low transactional speed.

Blockchain technologies are used by companies across sectors , including financial institutions, governments, the healthcare sector , eCommerce, real estate, legal industry, cryptocurrency, tech, and many more companies.

Here are some examples of how companies use blockchain technologies for their leverage:

• HSBC's Global Payments: HSBC utilized blockchain to revolutionize its global payment system. By implementing a blockchain-based platform, the bank streamlined international trade transactions, reducing the time to process documents from 5-10 days to 24 hours.
• Estonia's Digital Governance: Estonia is a global leader in digital governance. It implemented blockchain for securing public service records and e-governance through digital apps that citizens can interact with without the burden of bureaucracy.
• De Beers Diamond Tracking: De Beers implemented blockchain to track diamonds from the mine to the end customer. This ensures conflict-free diamonds and enhances consumer trust by providing a transparent product journey.

Blockchain application development essentials

How to make a blockchain? Developing a blockchain application requires careful planning and a clear understanding of the blockchain ecosystem. Here are the essential steps and considerations for blockchain application development:

1. Define the use case

Identify the problem you want to solve or the process you want to improve. Ensure that blockchain is the right technology for this purpose. Not all applications require blockchain's unique characteristics.

For example, a supply chain management system is a great use case to create your own blockchain because transparency is excellent for supply chains. On the other hand, a blockchain may be an overkill for a simple internal employee database.

2. Build the right blockchain team

When developing a blockchain application, it’s also essential to have a team with the right mix of skills, including blockchain expertise, smart contract development, cybersecurity knowledge, and experience in the relevant industry or sector.

A typical blockchain team consists of blockchain analysts who inspect data flow, blockchain developers and analysts, UI/UX designers, and QA engineers. These are the key specialists that should be on every blockchain development team, though a team can be bigger based on your needs.

3. Select the appropriate blockchain platform

Choose the right blockchain platform based on your project's requirements. Options include Ethereum for smart contracts and DApps, Hyperledger Fabric for private blockchains, or Binance Smart Chain for high-throughput DApps. The choice depends on consensus mechanism, transaction speed, scalability, and cost.

4. Design the blockchain instance

Decide on a private (permissioned) or public (permissionless) blockchain based on your needs. Private blockchains are more centralized but offer greater control and privacy, while public blockchains are decentralized and transparent.

5. Smart сontract development

If your application involves transactions or agreements, develop smart contracts. These are self-executing contracts with the terms of the agreement directly written into lines of code.

Approaches to building blockchain solutions

Blockchain solutions can be public, private, hybrid, or blockchain as a service. There is also smart contract development and developing blockchain from scratch. Let's look into the details regarding these different approaches:

1. Public blockchain development

This approach involves building applications on public blockchains like Ethereum, Bitcoin, or Binance Smart Chain, with Ethereum being the most popular. It's suitable for decentralized applications (DApps) that require transparency and are open to everyone.

• Use case: Cryptocurrency platforms, decentralized finance (DeFi) applications, NFT marketplaces.

2. Private blockchain development

Private or permissioned blockchains include Hyperledger Fabric or Corda. This is ideal for businesses that must restrict access to the blockchain network and maintain privacy and control over data.

• Use case: Supply chain management, internal record-keeping, enterprise-level solutions.

3. Hybrid blockchain development

Hybrid blockchains combine elements of both private and public blockchains. They offer a flexible solution tailored to specific business needs, providing privacy while enabling certain data to be publicly verifiable.

• Use case: Healthcare data management, legal and compliance records, and government services.

4. Blockchain as a Service (BaaS)

BaaS providers offer cloud-based solutions for blockchain apps and smart contracts. This suits businesses that want to use blockchain technology but do not want to invest in building and maintaining the infrastructure.

• Use case: Startups and SMEs looking to implement blockchain solutions quickly and experiment with blockchain applications.

5. Smart contract development

This method is about making contracts that run themselves by baking the agreement's terms into the code and automating processes and deals. These contracts are stored and replicated on the blockchain and are executed automatically when predetermined conditions are met. Smart contracts enable trustworthy transactions between anonymous parties without needing a central authority or particular legal system.

• Use case: Automated insurance claims, self-executing legal agreements, supply chain automation.

6. Custom blockchain development

For unique requirements, developing a custom blockchain from scratch might be necessary. It is quite difficult and resource-intensive to create a blockchain from scratch, but it offers flexibility and maximum customization.
