Hyperledger Fabric vs. public blockchain

Hyperledger Fabric

Hyperledger Fabric provides enterprises with tools, libraries, and frameworks to create their private blockchain. This allows them to create a personalized blockchain without worrying about the drawbacks of the public blockchain. Enterprises rely on it to ensure reliable and fast transactions with other enterprises.

Public blockchain

Public blockchains introduced the blockchain concept, from where it gained popularity. As the name suggests, they are public, meaning anyone and everyone can join the blockchain network. Being a public blockchain, it opens itself to many threats and attackers, encountering that they use computationally heavy consensus algorithms like POWProof of Work.

Hyperledger Fabric vs. public blockchain

The following table summarizes the differences between the Hyperledger Fabric and the public blockchain.

Access

• Hyperledger Fabric: It is a permissioned blockchainA blockchain that requires nodes to be verified before being added to the network., so access is granted only to members with a certificate issued by the certificate authority of the same network.
• Public blockchain: Anyone can join the blockchain network as it imposes no restrictions.

Application

• Hyperledger Fabric: It contains components and tools required to build a private blockchain, which is ideal for enterprises as they want privacy and speed.
• Public blockchain: Dapps can be built on top of public blockchains allowing businesses to interact with their clients.

Programming language

• Hyperledger Fabric: GO, Java and Javascript.
• Public blockchain: Solidity is being used to deploy smart contracts on Ethereum.

Number of transactions

• Hyperledger Fabric: As the members are verified, they do not require a computationally expensive consensus algorithm. Therefore, the transaction speed increases exponentially.
• Public blockchain: The transactions are low because they use consensus algorithms like Proof of Work, Proof of Stake, and more.

Coins

• Hyperledger Fabric: No coins are required as nodes do not need to be rewarded. Instead, it uses assets.
• Public blockchain: They use coins like Bitcoin, ETH, and more to reward the miners. This helps to attract more users to the blockchain.

Consensus algorithm

• Hyperledger Fabric: Any pluggable algorithm can be used by enterprises that fulfill their requirements.
• Public blockchain: Proof of Work, Proof of Stake, and more are chosen depending upon the blockchain.

Transaction execution

• Hyperledger Fabric: The execute-order-validate approach to executing the transaction helps Hyperledger Fabric deal with the scalability and performance issues as the transactions are executed as soon as they are requested. Then they are ordered and then validated.
• Public blockchain: The order-execute-validate approach is associated with traditional blockchains like bitcoin and Ethereum. In this approach, the transactions to be executed are ordered and then sent to all the peers, where they are executed sequentially.

The explanations above help us to understand the differences between the two blockchains. This helps us to choose the correct blockchain depending on the requirements.
