Blockchain technology has evolved significantly over the past decade, offering various solutions for various business needs. To choose the right type of blockchain for a project, it’s essential to understand the distinctions between the different types: public, private, hybrid, and consortium blockchains. Each of these has its characteristics, advantages, and limitations. This guide will explore these types and determine where Kalp Studio fits within this spectrum.

What is a Public Blockchain?

A public blockchain is an open, decentralised network that allows anyone to join, read, write, and participate in the consensus process. The following features characterise it:

• Decentralisation: No single entity controls the network, making it transparent and tamper-resistant.
• Permissionless: Anyone with an internet connection can join and participate in the network without permission.
• Transparency: Data on public blockchains is visible to everyone on the network, fostering transparency.
• Consensus Mechanisms: Common consensus protocols include Proof of Work (PoW) and Proof of Stake (PoS).

Examples of public blockchain: Bitcoin, Ethereum and Polkadot.

Use Cases of Public Blockchain

Public blockchains are ideal for cryptocurrencies like Bitcoin and Ethereum, decentralised finance (DeFi) platforms, and use cases where transparency and decentralisation are critical.

Advantages

• High Security: Due to the large number of participants, these blockchains are highly resistant to attacks.
• Transparency: Everyone can verify transactions, ensuring a high level of trust.

Disadvantages

• Scalability Issues: Public blockchains often struggle with slower transaction speeds due to the need for consensus among many participants.
• High Energy Consumption: Consensus mechanisms like PoW can be energy-intensive.

What is a Private Blockchain?

A private blockchain is a closed network where a single organisation controls access and maintains control over the system. It is more restrictive and centralised compared to public blockchains.

• Controlled Access: Only authorised participants can join and access the blockchain.
• Permissioned: Unlike permissionless blockchains, private blockchains require explicit permission for participation.
• Centralised: A central entity manages and controls the blockchain, making it less decentralised.

Examples of private blockchain: Hyperledger and Corda.

Use Cases

Private blockchains are well-suited for enterprise solutions where data privacy is paramount, such as supply chain management, internal audits, and inter-departmental communication.

Advantages

• Faster Transactions: Due to fewer participants and centralised control, transaction speeds are significantly faster.
• Data Privacy: Data is only accessible to authorised parties, making private blockchains ideal for businesses needing to protect sensitive information.

Disadvantages

• Lack of Decentralization: Centralization makes the blockchain less secure against certain attacks.
• Limited Transparency: The closed nature of private blockchains reduces transparency, which might not be ideal for use cases where openness is required.

What is a Hybrid Blockchain?

A hybrid blockchain combines elements of both public and private blockchains, offering the best of both worlds. It enables controlled access while still allowing certain aspects to be public.

• Selective Transparency: Certain data is public, while sensitive information is accessible only to authorised participants.
• Flexible Control: Organizations can control who can access specific parts of the blockchain.
• Interoperability: It allows for interoperability with public blockchain systems, making it easier to communicate with external parties.

Example of hybrid blockchain: IBM Food Trust.

Use Cases

Hybrid blockchains suit industries like finance, healthcare, and supply chains where transparency is needed but data privacy is equally important.

Advantages

• Customisable: Hybrid blockchains offer flexibility to customise access levels, making them suitable for various business requirements.
• Better Scalability: It can handle more transactions than purely public blockchains.

Disadvantages

• Complex Architecture: Building a hybrid blockchain can be complex due to the need to maintain both private and public components.
• Security Concerns: If not implemented correctly, hybrid blockchains can become vulnerable to attacks on the public aspects.

Here’s a comparison table of the types of blockchain for better understanding.

How Does Kalp Studio Use the Public Blockchain and Utilise It?

Kalp Studio is an application that leverages the capabilities of public blockchains to provide users with enhanced tools for building, testing, and deploying decentralised applications (dApps). Being built on top of public blockchains means it operates directly with decentralised networks like Holesky and Sepolia for Ethereum and AMOY for Polygon, or other blockchain platforms that are open and accessible to anyone.

Here's how Kalp Studio integrates with public blockchains:

1. Direct Interaction with Blockchain Networks:

Kalp Studio enables developers to interact with public blockchains, allowing them to deploy smart contracts, perform transactions, and run tests directly on networks like Ethereum and Polygon (other blockchains coming soon). This capability helps ensure that the applications built through Kalp Studio are decentralised, trustless, and tamper-resistant.

2. Decentralized Data Storage and Execution:

By building on public blockchains, Kalp Studio benefits from these networks' inherent security, transparency, and decentralisation. The data processed and stored through smart contracts on Kalp Studio is recorded on a public ledger, making it immutable and visible to anyone on the network.

3. Smart Contract Deployment and Management:

Kalp Studio simplifies deploying and managing smart contracts on public blockchains thanks to its Kalp Instant Deployer. It provides a user-friendly interface for developers, allowing them to create, compile, and deploy smart contracts without needing deep expertise in command-line tools. This makes the development process more accessible while leveraging the power of decentralised networks.

4. Public Accessibility and Transparency:

Since Kalp Studio is built on public blockchains, the applications developed using it can be verified and audited by anyone. This transparency builds trust in the dApps, as users can independently verify the code and transactions executed through the blockchain.

5. Integration with APIs and Decentralized Services:

Kalp Studio can integrate with various decentralised services and APIs, allowing developers to use blockchain-based tools like oracles and decentralised storage solutions all of this has been made possible by the Kalp API Gateway. These integrations are made possible due to the open nature of public blockchains, enabling Kalp Studio to create a comprehensive development environment.

Conclusion

The choice between public, private, hybrid, and consortium blockchains depends on the specific needs of a project, such as the level of transparency, control, and security required. Public blockchains offer openness and decentralisation, private blockchains provide control and speed, while hybrid blockchains balance transparency and privacy.

By utilizing the robust infrastructure of public blockchains, Kalp Studio provides a powerful platform for building decentralized applications that are secure, transparent, and aligned with the ethos of blockchain technology.
