Choosing the Suitable Blockchain for Your Business
Blockchain technology is rapidly evolving and making its way into various domains. While previously limited to FinTech and IT sectors, the potential of blockchain for business is now recognized across different industries. With the increased demand, the supply of blockchain solutions for different business sectors, ranging from mobile gaming to ride-hailing aggregators, has grown exponentially. However, this abundance of options can be overwhelming. If you are considering leveraging blockchain for your project, navigating through the choices can be challenging. This article aims to provide guidance on where to begin.
Understanding Blockchain in a Nutshell
In simple terms, blockchain can be defined as a chain of interconnected blocks. Each block contains information and is linked to the previous block. Conceptually, you can envision a blockchain as a vast database distributed across a network, rather than being centralized in a single location like a city archive. The interconnectivity of blocks makes it extremely difficult to alter information recorded in the blockchain since each block retains a portion of the previous block’s data.
The original purpose of blockchain was to introduce a more secure and transparent method of decentralized data transfer, eliminating the need for intermediaries. Blockchain finds applications in various sectors, including banking, marketplaces, payment systems, government agencies, election systems, and healthcare. In an ideal world, blockchain has the potential to replace or enhance these existing systems.
Types of Blockchains
Over the past few years, numerous blockchains have emerged, offering diverse features and functionalities. Vitalik Buterin, one of the creators of the Ethereum network, categorizes blockchains into three main types: public, private, and consortium.
Public blockchains are accessible to anyone. Participants can create blocks, view information stored within them, and engage in the blockchain’s operations. These blockchains are decentralized, meaning they lack a central authority. Consensus mechanisms, which will be discussed later, validate transactions and ensure the accuracy of recorded information. Well-known examples of public blockchains include Bitcoin, Ethereum, Tron, and others.
Private Blockchains: In private blockchains, only authorized participants have the privilege to record information. The level of information accessibility varies, depending on the nature and purpose of the blockchain. Private networks find applications in large enterprises for efficient information storage and transfer. They can also be utilized by government institutions as replacements for land registries and bureaucratic departments.
Consortium Blockchains: Consortium blockchains are partially decentralized networks governed by a group of selected organizations. These networks enable quick transactions and information exchange among the consortium participants. Information accessibility can be either public or restricted.
If you are unable to find a suitable blockchain, it is possible to create a customized one. In theory, any company with sufficient resources can develop its own blockchain that caters to its specific business requirements. However, this approach demands significant financial investment and a reliable team of programmers.
The consensus mechanism is a crucial aspect of blockchain functionality. It ensures the reliability and accuracy of data recorded in the blockchain. In simple terms, it is a specialized algorithm that validates transactions and verifies the correctness of recorded information.
There are numerous consensus algorithms, each with its own principles and characteristics. Let’s explore some of them in further detail:
Proof-of-Work (PoW) is one of the earliest and most well-known blockchain consensus algorithms, popularized by Bitcoin. In this algorithm, a decentralized network of computers, known as miners, compete with each other to solve a mathematical problem and validate transactions. The miner that successfully solves the problem confirms the transaction, adds a new block to the chain, and receives a reward. However, PoW has drawbacks, including high energy consumption and slow transaction speeds.
Proof-of-Stake (PoS) was developed as a faster and more energy-efficient alternative to PoW. In this algorithm, any user can become a network validator by holding a certain amount of coins as collateral. Validators are randomly chosen and earn a commission for verifying and confirming blocks on the network. The likelihood of being selected as a validator increases with the number of coins staked. The advantages of PoS include its eco-friendliness and quicker transaction speeds. However, there is a concern of centralization, as validators with a significant number of coins can gain control over a large portion of the network.
Proof-of-Burn (PoB) is a consensus algorithm similar to PoW but doesn’t require powerful computers or graphics cards. Instead, users invest in virtual mining hardware. During the block validation process, cryptocurrency is deliberately “burned” to ensure network reliability. The more coins a user burns to support system stability, the higher their chances of being selected as a validator. PoB offers benefits such as low energy consumption and the potential positive impact on the value of coins within the network. However, this consensus mechanism is more suitable for mature projects that have already issued their coins.
How to Select the Ideal Blockchain for Your Business
If your business primarily focuses on accepting cryptocurrency payments, creating an address and addressing legal requirements would suffice. However, for more complex operations requiring automation, hosting smart contracts on a public network is recommended. Another option is to develop a custom blockchain.
When choosing a blockchain for your project or application, there are several crucial factors to consider.
Determine the Type of Blockchain: decide whether a private or public blockchain is more suitable based on the logic and benefits for your business. In certain cases, using a public blockchain may not be practical, and it may be more advantageous to opt for closed software solutions.
Public Blockchains
Public blockchains are accessible to anyone without the need for third-party permission. They offer benefits such as global data exchange transparency and reliability. However, the openness of public blockchains leaves them susceptible to potential discrediting. It’s important to note that the rules of a public blockchain cannot be altered once they are approved during the initial development phase.
Private Blockchains
Private blockchains are accessible only to a trusted circle of individuals. Network owners have control over its operation, and the system rules can be modified based on various factors like participant numbers, authorization levels, and power distribution. Private blockchains can function autonomously or in connection with other chains. They are commonly employed by companies in the oil and gas sector. Generally, private blockchains instill a higher level of trust compared to public ones. Developing a private blockchain necessitates the involvement of computer and legal experts. Additionally, you’ll need to create your own fork, which includes services for monitoring system operations and various user tools. The network will undergo testing, improvement, and troubleshooting before being evaluated by experts.
