Top 5 Blockchain Protocols That You Should Know


Are you looking to learn about enterprise blockchain protocol? If you do, then you have come to the right place. Today, we are going to list the top 5 blockchain protocols that you should know.

If you look at the internet, then you will find that everything works according to a plan. A browser sends signals to a server, and in return, the browser receives the website or the resources the user is looking for. All of these are possible because of the internet protocols that make it happen.

The keyword here is “protocol.”

Top 5 Blockchain Protocol That You Should Know

Top Blockchain Protocols

What is a Protocol?

A protocol is the rules and guidelines that are used to achieve a particular task. For the internet, the protocol aims to provide a framework(rules and guidelines) for data transfer. These rules are necessary to ensure that data can be transferred efficiently. 

Protocols are meant to work like these, and nothing is different in the case of blockchain.

Enterprise blockchain protocol or blockchain protocols are designed to maintain different aspects of blockchain. This means that there are blockchain security protocols, network protocols, and blockchain consensus protocols. All these protocols, when combined, mainly combine into becoming a blockchain framework.

Our focus in the article is to list the enterprise blockchain protocols. We will also discuss some of the blockchain consensus protocols.

Why does blockchain need a protocol?

The core idea behind blockchain is its decentralized nature. This means that centralized authority is absent. To make it work as intended, protocols are used. As there is no centralized entity, peers or nodes need to be connected and maintain a ledger copy. There is a consensus method that also works in the network to validate transactions into blocks.

These blocks, once created, cannot be altered. All of this is done using protocols. It acts as a guideline. This also means that we have different types of blockchains that try to do things differently, depending on what they want to achieve from their efforts.

Bitcoin, for example, is a cryptocurrency that aims to improve decentralized value exchange. However, right now, it has become more of an asset used for preserving value, just like gold.

Blockchain is also thriving rapidly in the past few years. It has come along a long way from what bitcoin has started. Right now, there are dedicated people, teams, and companies who are trying to revolutionize blockchain with a better solution that can be implemented in different scenarios.

Hyperledger is an open-source enterprise framework. It is managed by the Linux Foundation. It is an umbrella project which has tons of frameworks and protocols. As it is open-source, anyone with the right expertise can contribute to the project. Also, Hyperledger is all about permissioned blockchain.

The main aim is to provide enterprise blockchain solutions a universal framework or guidelines for blockchain implementation. There are many tech giants that are currently participating in the project, working on the same vision of creating a protocol that can be followed by enterprise solutions.

It was created in 2015. Right now, more than 260 organizations are working towards creating an industry-grade enterprise solution. Hyperledger has a strong security blockchain protocol.

Benefits of Hyperledger

There are multiple benefits of Hyperledger. They are as below

  • Cutting edge technology development
  • Enhanced productivity with the help of frameworks and tools
  • Good quality of code due to open-source nature
  • Better at handling intellectual property
  • Collaborative approach

The key projects within the Hyperledger framework as below:

  • Hyperledger Besu
  • Hyperledger Fabric
  • Hyperledger Iroha
  • Hyperledger Indy
  • Hyperledger Sawtooth
  • Hyperledger Burrow

Hyperledger also offers a lot of tools, including Avalon, Cello, Caliper, and others.

To learn about their tools, libraries, and framework, check out their projects page.

You should also check out our master guide on Hyperledger, which discusses the framework in detail.


Quorum is yet another enterprise blockchain protocol that is aimed to solve finance sector problems. JP Morgan invented Quorum, which can be described as an enterprise-focused Ethereum blockchain. This protocol-based system is key when it comes to solving finance related problems. It can change how financial enterprises function and implement blockchain in-house.

Quorum, just like Hyperledger, is an open-source project and is available under the LGPL 3.0 license. It benefits from Ethereum architecture and approach. With over 10,000+ commits, it is growing into one of the best possible enterprise blockchain framework. Also, it can be used for other industries and use-cases. The protocol-based design makes it possible to serve permissioned networks better.

The key features of Quorum blockchain include

  • Better performance
  • Voting-based consensus mechanisms
  • Open-source
  • Mature
  • Trustworthy and enterprise-ready
  • Community-driven
  • Enhanced transactions and contract privacy

Quorum architecture includes three important components — Quorum node, constellation transaction management, and enclave. It also utilizes a raft-based consensus and Istanbul BFT.

R3 Corda is also a promising enterprise protocol that is built from scratch. It is handled by the R3 banking consortium and is best suited for banking and finance-related organizations. It utilizes distributed ledger software. It utilizes consensus algorithms to ensure transparency, traceability, and validate transactions.

It also offers smart contracts, which means that most of the banking solutions can be automated. The principal features of R3 Corda include the following

  • The ability to create smart contracts
  • Offers uniqueness services and timestamping with notary pools
  • Flow framework that enables enterprises to write complex protocols and make them work with users.

Corda, just like the other blockchain protocols discussed until now, is open source and permissioned. This makes it an ideal solution for enterprises that want to make the most out of the Corda R3 architecture.

The five key standards of the Corda architecture include the following:

  • Longevity
  • Secure
  • Stable
  • Scale
  • Interoperable

Also, the business principles on the Corda platform include the following:

  • Privacy
  • Legal Footing
  • Assured Identity
  • Immutability
  • Open System
  • Inclusion

Right now, the ecosystem is thriving and has more than 200 members from different industries.

Enterprise Ethereum

Ethereum is one of the best public blockchain solutions out there. It offers a wide range of features, including smart contracts, dApp creation, and much more. However, to make it feasible for enterprise, it needed to be permissioned. This is where enterprise Ethereum comes in. It lets enterprises create private-permissioned networks fully capable of scaling to enterprise needs. The private chains created using Enterprise Ehereum are separated from public chains. But the private chains are completely capable of interacting with public chains if needed.

The key difference between Ethereum and Enterprise Ethereum is permissioning. Enterprise Ethereum also offers a better privacy level with improved performance and scalability. 

The Enterprise Ethereum Alliance maintains it. Right now, there are 300+ member companies from 45+ countries. It also has 1400+ individual members.

The key aim for the Enterprise Ethereum Alliance include the following:

  • Open source standard
  • Improves alongside with Ethereum
  • Cross-industry development
