What are the Testnet and the Mainnet?


The two technical terms Testnet and Mainnet are used every day in the world of Cryptocurrency. Everyday transactions of billions of dollars are made on Crypto Exchanges. Transactions are made in the form of crypto tokens and NFTs minting which are based on blockchain technology. Currently, thousands of cryptocurrency exchanges, DApps, and blockchains are released every day. 

So, without testing the functionality of these platforms is it possible to launch these platforms? Absolutely NO because if there any problem occurred during the transactions then, millions of individuals can lose their money and the whole cryptocurrency market would collapse. For solving these problems the existence of Testnet and Mainnet come into play.

What is a Testnet?

A testnet is a replica of the original version of the project on blockchain initiatives earlier than they may be prepared to be launched. It is an easy manner for programmers and builders to create, modify, and take a look at the functionalities in their project, in addition, to revealing its overall performance earlier than making it reachable to the public. Here, builders can troubleshoot any troubles and connect any bugs.

The transactions at the testnet are `fake` seeing that they may be taking a look at transactions, and not using a transaction expense incurred and no deployment expenses required with the aid of using developers. Since the cash at the testnet is worthless, there may be no financial incentive for miners to mine seeing that their simplest reason is to facilitate transaction trying out.

All though crypto projects offer a reward for the users and also for devs who are going to do a transaction on the testnet environment. Through this process, devs can get bugs and troubles faster than usual. It is helpful for both, the project and the user who is testing the transactions on it.

It is also common for developers to use a testnet for developing and testing their own blockchains before going on to launch them on their own. These testnets facilitate faster and safer mainnet launches.


Importance of Testnet:

1. Free testing

For blockchains that permit clever agreement functionality, local cash is required to be spent so that you can execute clever agreement transactions. It might be extraordinarily luxurious for builders to check out their software functions or run experiments at the mainnet for the reason that they might then want to shop for real-fee cash in bulk.

Any dApp which desires to onboard, desires to undergo a segment of trying out and fixes. New patches, features, and many others are first examined withinside the testnet. Some basic testings are listed below:

  • Load Testing
  • Security Testing
  • Disaster Recovery 
  • Blockchain Testing
  • Integration Testing 

And so on….

2. Constant development

Blockchain generation remains withinside the infancy tiers and an incredible quantity of checking out and improvement is wanted to allow mainstream adoption and usage. For instance, one of the major troubles which can be being addressed withinside the blockchain network is scalability.

Constant studies and improvement are being undertaken via way of means of a huge variety of tasks to decorate a blockchain`s functionality of processing greater transactions. In order to continuously decorate a blockchain`s capabilities, several checking out on clever settlement functionality, transactions, and the mining method should be undertaken.

The testnet serves as a simulation of how the real blockchain protocol (mainnet) might paintings below real-international conditions.

3. Prevent Disruption

A testnet permits testers and alertness builders to test the functions and features of the protocol in a separate environment, without disturbing approximately disrupting the principle blockchain.

Making the checks at the mainnet could be a nightmare because the complicated interactions among additives withinside the protocol ought to compromise the community or spoil the principle chain.

This could purpose big disruptions to the blockchain and will undermine the protocol. It is, for this reason, a not unusual place exercise for initiatives to run a prototype on a testnet.

What is a Mainnet?

A Mainnet is just vice versa of Testnet. As from the name it is visible that it is the main network where all the real transactions happen. The well-known cryptocoin Bitcoin is currently operating on the mainnet and this means all the transactions happening on the bitcoin blockchain are real and have equal to the transfer of the values.

It is always regarded as more mature to work on a project with a mainnet. The user can feel confident that the project has put forth a lot of effort and resources into its blockchain. Introducing the mainnet followed the completion of a rigorous evaluation process.

A mainnet includes a completely released internet wherein cryptocurrency transactions may be processed efficiently, validated accurately, and recorded securely. By deploying a mainnet, its builders are pointing out that they’ve completely believed in their blockchain`s capacity.

As a completely functioning blockchain, mainnets may be used to ship and obtain any transaction, inside the shape of cryptocurrency or non-fungible tokens (NFTs), amongst others, or switch information. Additionally, a mainnet can run an assignment that calls for that unique blockchain protocol, for instance, DApps at the Ethereum mainnet.

Importance of Mainnet:

1. Credibility

The credibility of a challenge that has a mainnet is undoubtedly greater than the credibility of a challenge without one. Using the local currency of the blockchain, individuals can transact with one another using a mainnet.

A node interested in contributing to the network can download the protocol and become a collaborator. In the event that the blockchain is open-sourced and unfastened for use by all, the underlying codes are visible to the public, and any problems or concerns can be raised by anyone.

Mainnet lifestyles facilitate the emergence of a social environment where people can express themselves and transact in complete transparency. In the absence of a mainnet, the challenge is merely conceptual or theoretical, and it does not require an operating product that individuals can check out.

2. Use cases

Before launching a mainnet a blockchain is already companions with utility creators. Hence a number of the programs were released in conjunction with the mainnet release. This offers use instances for in addition dApps to onboard the blockchain.

3. Proof of development

The Mainnet is verifiable evidence that the assignment has resulted in a functioning, practical blockchain for real-world transactions. An assignment with a mainnet is in progress and is now staying. Furthermore, the stay mainnet could put to the test the capabilities of the blockchain, since the public can participate within the community and any malfunction should compromise its internal workings.

As a result, launching the mainnet requires a large number of assets and improvements to ensure that everything is operating as it should. In addition to that, a mainnet is an operational indicator that the project is meeting its objectives.


Testnet vs. Mainnet: The Main Differences

• Purpose

The testnet is a testing environment whereas the mainnet is the real place where the functionality of blockchain is observed by the public.

• Cost of Operation

In the testnet, the tokens are dummy and do not hold any value and hence cannot be exchanged for value so it is less costly to get a dummy coin. But in mainnet, the cost of operation is greater than testnet because here the tokens have a real value. And every transaction requires a transaction fee which is to be provided in real token value.

• Network ID

A network ID helps the developer to identify, whether the transaction is done in mainnet or testnet. As of we know that the network id in testnet and mainnet id are different

• Genesis block

A genesis block is a unique block for testnet and mainnet. It is regarded as the first block of the blockchain.

• Node

Nodes are powerful computers that verify the transactions occurring on the blockchain. Hence a testnet requires a small number of nodes as compared to a mainnet

• Transaction frequency

Transaction frequency is defined as the no. of transactions made on the blockchain in 1 sec. Here in the testnet, the transaction frequency is lower than in the mainnet. All though during the load test, it is also a bit high for the testnet.



A testnet and mainnet are the two different blockchains of the same project. The former is used as the testing environment whereas the latter is used as the field environment. Tenets are used to check the functionality of the blockchain and after identification and proper fixing it than it is released as mainnet.

Sometimes testnets are offered to the public to do fake transactions to check its load and hence for this, people are rewarded with the tokens of the project when its mainnet is launched. In the future, we will be discussing how can we earn using a testnet project.
