### What are dApps (decentralized applications)?
Decentralized applications, or dApps, run on a blockchain or peer-to-peer (P2P) network. They spread across the network and connect their users with each other using blockchain technology and smart contracts. The main advantage of dApps is that they do not need an intermediary company. Instead, they use lines of computer code that can be customized for different use cases. In other words, you can even make it publicly available to anyone with access to the Internet.
### Public vs. Private blockchains
In short, blockchain technology is a digital ledger that records and verifies information on multiple computers. It is a distributed database that keeps an orderly chain of records and makes it impossible to falsify information. At its core, there are two types of this network: private and public. 

A public blockchain is a series of blocks that can be “read” by anyone in the world. That is, any user of the network can send transactions, confirm them, and contribute to consensus. Public blockchains are typically used for cryptocurrencies, but many other industries that require transparency, security, and trust leverage them as well. 

Private blockchains, on the other hand, offer limited access to data. Only predefined users can log on to the network and confirm transactions. This guarantees increased control and confidentiality, which is beneficial for organizations such as banks, healthcare facilities, and government agencies. 

When choosing the type of blockchain to develop your mobile application, consider your business needs. If transparency and trust are your main priorities, a public blockchain is the perfect option. However, if you aim to work with confidential information, look no further than a private blockchain. 

### Smart contracts
In the context of blockchain, another interesting phrase that comes to mind is smart contracts. This is an agreement that is drawn up using a combination of code and blockchain, which can only be concluded and terminated using a computer program. 

This technology is popular due to its automation. When predefined conditions are met, the smart contract appears, automating tasks and ensuring that all parties involved play by the rules. This eliminates the need for intermediaries, simplifies processes, and builds trust through complete transparency. 

## Blockchain platforms and languages <a name="blockchain-platforms-and-languages"></a>
There are various building blocks you need to understand before starting work on blockchain app development. The main thing to consider is platforms and programming languages that cover a lot of purposes. So that you don’t get lost in the flow of information, in the next sections, we’ll introduce popular technologies commonly used in the development process.

### Ethereum and Solidity
Ethereum is an open-source, decentralized network that boasts a robust infrastructure designed to run smart contracts — self-executing programs that automate agreements and transactions. Solidity is Ethereum’s native programming language, allowing developers to craft these smart contracts with precision. Being inspired by popular languages like C++, Python, and JavaScript, it provides a familiar and readable syntax for programmers. 

However, no technology is perfect. Ethereum faces scalability challenges, meaning it can get congested during periods of high activity. Solidity, while powerful, requires a strong grasp of coding concepts and blockchain fundamentals to avoid vulnerabilities in smart contracts.  

Despite these limitations, Ethereum and Solidity remain a powerful duo. Their strengths make them a perfect starting point for anyone exploring the exciting world of building blockchain applications.

### Hyperledger and GoLang
While Ethereum dominates the public blockchain network, enterprise needs often demand a different approach. That’s where Hyperledger, an open-source project under the Linux Foundation, offers a suite of frameworks for building enterprise-grade blockchain solutions. Unlike Ethereum, it focuses on private, permissioned networks, allowing businesses to control who participates and what information is shared. This ensures greater privacy and regulatory compliance, which is crucial for many enterprises.

GoLang is the preferred language for developing Hyperledger applications. Known for speed, concurrency features, and growing popularity, it is a perfect fit for building scalable and performant blockchain applications. Plus, GoLang’s static typing helps prevent errors, a critical aspect of secure enterprise deployments.

### Binance Smart Chain and C++
Beyond the big names, innovative platforms like Binance Smart Chain (BSC) are rising through the ranks. BSC, built by the crypto powerhouse Binance, offers a high-performance alternative to Ethereum. This smart contract platform boasts blazing-fast transaction speeds and significantly lower fees, making it ideal for cost-sensitive applications.

Binance Smart Chain utilizes C++ for smart contract development. This powerful language, known for its performance and memory management, allows developers to create highly optimized smart contracts. C++’s ability to handle complex tasks efficiently makes it suitable for building robust and scalable blockchain infrastructure.
