1. About Blockchain App Development 

1.1. What is Blockchain App Development? 

A blockchain is a distributed ledger technology (DLT) that securely records transactions and tracks assets, whether those are physical assets, like money or real estate, or nonphysical assets, like copyrights—within a network.

Blockchain development is the process of building, maintaining, and designing blockchain apps and systems. Undoubtedly, it is a complex process that requires a deep understanding of the underlying technology.

1.2. Benefits of blockchain apps 

Blockchain technology has a number of advantages over traditional systems, including:

  • Security: Blockchain is a very secure technology because it uses cryptography to protect data. Consequently, this makes it difficult for hackers to tamper with or steal data stored on a blockchain.
  • Transparency: Blockchain is a transparent technology because all transactions are recorded on a public ledger. This makes it easy to track and audit transactions, and to ensure that they are accurate and legitimate.
  • Immutability: Once data is stored on a blockchain, it cannot be changed or deleted. This makes blockchain ideal for applications where data integrity is critical, such as supply chain management and financial services.
  • Efficiency: You can use blockchain to automate transactions and reduce the need for intermediaries, which can save time and money.
  • Trust: Blockchain can help to build trust between parties by providing a secure and transparent record of transactions. This is important for applications where trust is essential, such as crowdfunding and cross-border payments.

In short, these advantages make blockchain a promising technology with the potential to revolutionise a wide range of industries, such as supply chain, finance, healthcare, government, etc.
