9 Best Programming Languages for Learning Blockchain Development

Blockchain technology is getting popular day-by-day and the skill of blockchain development will put you in the right place.

Before knowing about programming languages for blockchain development, let’s see what is exactly blockchain development.

Years ago, as humans were evolving there was a barter system (before money was invented). Humans exchanged some types of goods for some other kinds of goods; say apples for grains.

This changed as our society started developing and we started trading across long distances.

Money was invented and institutions like banks for organizing money and forming rules were established.

Let’s say you want to send money online through your bank account to a friend. Who verifies this transaction and who ensures there’s no double-spending?

Well, here respective bank verifies the transactions and the technology is built in such a way that there’s no double-spending.

So, we have banks, through which you can do transactions online. There’s an application of a bank, or a wallet you use such as PayPal to make these transactions possible.

Here, you know just your transaction history and not anybody else’s. The data of each user is centralized with respective banks.

Let’s consider another example where you may have social media accounts like Facebook, Instagram or you use applications like Uber which help you book a cab.

These are companies who own their respective applications and the data of the users using these applications are here as well centralized.

If an attacker wants to have this data it attacks the respective centralized application data. At present, what we see generally are centralized applications.

What is blockchain development?

Blockchain technology is through which a person can do transactions without the need of a middleman.

It is a decentralized technology. In the example of banks, through blockchain technology, you would not require banks.

It is a peer-to-peer network technology where every user of it has a history of whole transactions that have taken place.

Also, it is append-only technology i.e. no user can go back and make changes in the already done transactions.

The transactions as they occur get appended to the chain of blocks (block – collection of recent transactions that are happened and are verified). One advantage here is the cost of the transaction is reduced compared to the charges that banks take.

Also, though the data is available to every user, the identity of each user is protected through private key cryptography.

It’s not an application. It’s not a company. Since it’s decentralized, and the record is replicated on every computer that uses the network, it makes it more secure and hard to tamper with.

Since it is not owned by a company, it is hard to update the software of blockchain, because if you create a decentralized structure where no one’s in control, you also don’t have somebody with the ability to necessarily update the software (also known as permissionless blockchains example – Bitcoin).

It also has other uses, like in supply chain management, let’s say you go to Walmart to buy mango slices.

Now, through this technology you would actually come to know who produced it, from where was it processed, and all the other things it’s been through like packaging, basically knowing the entire sequence of steps that the product is been through giving you as a consumer more trust on the safety of food.

Blockchain gives the technological capability of creating a record of the human exchange of currency, and all kinds of digital and physical assets.

In a nutshell – blockchain allows users to exchange value with the help of a distributed ledger without third parties.

It’s a concept that can be coded using various programming languages.

Let’s have a look at them:
