What are blockchain protocols?

Quick take:

  • Blockchain protocols govern how transactions on that chain are enacted
  • Protocols are needed as there is no central authority governing transactions
  • There are many types of protocols for specific use cases

What are blockchain protocols? 

Blockchain protocols are rule sets that enable data to be securely shared across a network.

They provide a framework for how information is exchanged between different machines, regardless of their hardware and software differences.

Protocols help to ensure that all participants in the network have access to the same information and can communicate with each other in an efficient and secure manner.

The protocols used in blockchain networks are designed to provide a secure environment for transactions and data storage.

They also help to monitor the network, ensuring that all nodes are behaving correctly and no malicious activity is taking place. The protocols also allow users to verify transactions, ensuring that they are valid before they are added to the blockchain ledger.

By using these protocols, blockchain networks can remain secure while allowing users to trustlessly exchange data without fear of tampering or fraud.

If you're not yet aware of blockchain protocols, you might be aware of some of the existing internet protocols including...

  • TCP/IP
  • DNS

TCP/IP stands for Transmission Control Protocol/Internet Protocol and is responsible for establishing connections between computers over a network.

HTTPS stands for Hypertext Transfer Protocol Secure and is used to encrypt data sent over the internet, providing an extra layer of security.

Finally, DNS stands for Domain Name System and is responsible for translating domain names into IP addresses so that computers can locate one another on the web.

Why does blockchain need protocols? 

Protocols are essential for blockchain because there's no centralized authority deciding how data should be shared. 

The decentralized nature of the network wouldn't work if there weren't any rules to help govern how network members interact with one another.  

Without protocols, blockchain and Web3 as a whole would truly be a wild west where anything went. 

Either that or everything would simply collapse as there would be no rule sets to govern how to interact with one another.  

One of the benefits of blockchain protocols that's rarely talked about is how they help increase scalability by allowing more transactions to take place at once without compromising security or reliability.

With protocols, blockchains can become more efficient and secure while still providing users with fast transaction times.

Examples of blockchain protocols


Hyperledger is an open-source project that provides a suite of tools for enterprises to quickly deploy Blockchain technologies.

It is supported by the Linux Foundation, which has supplied significant expertise to accelerate the development of the protocol. Hyperledger is highly compatible with Linux, making it ideal for use on the same servers that are widely used in today's business world.

The Hyperledger protocol comes with its own libraries that help speed up development and make it easier for businesses to implement Blockchain solutions.

This makes it a popular choice for many companies looking to take advantage of the benefits of distributed ledger technology.

Additionally, Hyperledger offers a wide range of features such as smart contract support, data privacy protection, and scalability options that make it suitable for a variety of applications. With its growing popularity, Hyperledger is becoming an increasingly important part of enterprise Blockchain solutions.


Multichain specializes in the development of private Blockchains for for-profit corporations.

It provides an API that can be used by Blockchain development services to streamline integration and accelerate deployment.

Multichain’s main focus is on creating a platform that works alongside fiat currencies and physical stores of value, rather than replacing them with digital mediums of exchange. This allows companies to take advantage of the benefits of Blockchain technology without having to completely abandon traditional financial systems.

The advantages of using Multichain are numerous. By utilizing its API, companies can reduce the time it takes to develop new applications and transactions on their private Blockchains.

Furthermore, they can use Multichain’s platform to securely store data and facilitate faster transactions between parties.

Additionally, Multichain offers a variety of tools that allow users to customize their own private Blockchains according to their specific needs.

All in all, Multichain is an excellent choice for businesses looking to leverage the power of Blockchain technology without having to completely replace existing financial systems.

Ethereum Enterprise

Ethereum Enterprise is a version of Ethereum software specifically designed for business use cases.

It provides businesses with the ability to rapidly develop large-scale applications to exchange value, while still taking full advantage of the latest Ethereum code.

The major advantage of Ethereum Enterprise is that it allows businesses to create proprietary variants of Ethereum while still taking full advantage of the latest Ethereum code.

This means that businesses can customize their own versions of the software without having to worry about violating any licenses or restrictions.

Ethereum Enterprise also offers a range of other features and benefits that make it attractive for businesses.

For example, it has built-in support for smart contracts, which allow users to automate certain processes within their applications. Additionally, its scalability makes it suitable for large-scale projects and its security features ensure that data remains safe and secure at all times.

All in all, Ethereum Enterprise is an excellent choice for businesses looking to take advantage of blockchain technology in order to streamline their operations and increase efficiency.
