One of the inventions of the twenty-first century that has received the greatest excitement is blockchain technology. How to become a blockchain developer? what blockchain is? In this post I will discuss about this.

Blockchains, which were first created to support Bitcoin, now power dozens more cryptocurrencies, and developers are seeking to incorporate the technology into industries including medical, the arts, and banking.

It might be useful to comprehend how blockchain works, why it has value, and how it differs from other internet technologies in order to comprehend the rising interest.

What is Blockchain?

A blockchain is a digital record of transactions protected against hacking and modification by a network of computers.

With the use of technology, people may transact with one another securely without the need for a middleman like a bank, government, or other third parties.

Encryption is used to interconnect the developing collection of data called blocks. Mentoring computer systems use time stamps to verify every transaction, before being added to an increasing data chain. The data is unchangeable after it has been recorded.

Blockchain technology has gained popularity with the rising usage of Bitcoin, Ethereum, and other cryptocurrencies, but it also has potential uses in the legal sector, real estate transactions, the medical field, and any other area that requires the authorization and documentation of a sequence of activities or transactions.

Explaining blockchain technology

Here is an explanation of how blockchain, also known as distributed ledger technology, works using the Bitcoin system as an example:

  • A network of strong computers known as nodes receives and transmits transactions for buying and selling bitcoin.
  • Using computer algorithms, this network of thousands of nodes competes to confirm the transaction. Bitcoin mining is what this is called. The miner who is the first to successfully finish a new block is rewarded with Bitcoin for their efforts. Newly created Bitcoin and network fees—which are charged to the buyer and seller—are used to pay for these benefits. The amount of transactions will determine whether the fees increase or decrease.
  • The sale is recorded as part of a block on the distributed ledger once the purchase has been cryptographically verified. The transaction must then be confirmed by the majority of the network.
  • The block is permanently linked to all previous blocks of bitcoin exchanges, to use a cryptographic thumbprint defined as a hash, and the sale is processed.

In a dissertation from 1982 that discussed “the architecture of a distributed computer system that may be formed, maintained, and trusted by mutually suspicious organizations,” the idea of blockchain technology initially surfaced in scholarly works.

How to become a Blockchain developer?

In the present state of the IT industry, blockchain is undoubtedly one of the top rising technological fields. According to statistics, the worldwide market for blockchain technology is expected to increase by over $20 billion by 2025.

Advantages and Disadvantages of blockchain

The following are some advantages and drawbacks of how cryptocurrency blockchain technology functions:

Advantage of blockchain


While the Federal Reserve prints the U.S. dollar, no government body is answerable of or issues Bitcoin or other cryptocurrency.

Additionally, this means that no government or organization will longer be ready to decide the longer term of a public blockchain.

The absence of middlemen lowers costs since there are not any third-party transaction fees. Time efficiency is another advantage of how blockchain operates; unlike banks and other middlemen, the blockchain is accessible for business around-the-clock, daily of the year.

Combined with confidentiality

On computers spread across the network, the Bitcoin blockchain keeps a record of each transaction.

The ownership of every wallet related to these public addresses is anonymous and not documented, but the address and transaction history of those wallets, which store the bitcoin, make transactions totally visible.

Precision and safety

There is a lesser chance of mistake since there’s minimal human involvement throughout the transaction. it’s vanishingly difficult to falsify or modify information since each transaction must be verified and logged by a majority of the network nodes.

Additionally, this stops someone from employing a Bitcoin quite once.

Applications for both public and personal blockchains

Efficiency gains brought forth by blockchain technology might go much beyond virtual currency. as example, anybody may join the general public blockchain network where Bitcoin is found.

However, a range of business applications is also developed on private blockchain networks, where businesses can manage who joins:

  • Blockchain supply chain: Organizations are already offering private network solutions that use blockchain technology to more precisely trace product supply chains, including IBM Blockchain. as an example, businesses may utilize the technology to swiftly determine where delivered and sold recalled food goods.
  • Electronic medical records: per Deloitte Consulting, a national blockchain network “may increase efficiency and enable improved health outcomes for patients.”
  • Smart contracts: Using blockchain technology, contract terms are also updated or altered automatically in response to the fulfillment of a specified set of criteria.
  • Elections conducted digitally: Some developers are developing blockchain technology to be used in elections.
  • Property sales: Supporters claim that blockchain technology could also be used for a range of asset sales, including those involving property, automobiles, and investment portfolios.

Disadvantages of blockchain

Crypto appeals to criminals

A number of recent technologies have their early users among criminal organizations. thanks to the secrecy they supply, they utilize cryptocurrencies like bitcoin for both payment and to kill bitcoin holders.

Customers of Silk Road, a black market online marketplace for unlawful goods and services that the FBI close up in 2013, offered Bitcoin as an example. Recently, ransomware attacked Colonial Pipeline, and to unlock its computer systems, the company paid $4.4 million in bitcoin.

While this has been happening, the amount of investment frauds using Bitcoin has increased dramatically.

According to the Federal Trade Commission, between October 2020 and March 2021, programs promising quick gains cost almost 7,000 people $80 million, a nearly 1,000% rise in reported losses year over year.

Cryptocurrencies on the blockchain are quite unstable

Is blockchain a wise investment, ponder some. That relies on your investing goals and risk tolerance.

In 2021, cryptocurrency’s appeal skyrocketed, with Bitcoin reaching record damage of about $65,000. However, the price of Bitcoin and a number of other cryptocurrencies had decreased by quite half by the spring of 2022.

The usage of cryptocurrencies remains uncommon

A large number of exchanges, brokerages, and payment platforms presently offer bitcoin for sale, and many companies, like PayPal and Microsoft, accept it as payment.

However, using blockchain currencies like bitcoin to form purchases continues to be uncommon.

Additionally, additionally to any state and native taxes already paid on the great or service, users who sell bitcoin for purchases on payment platforms like PayPal must pay capital gains taxes on the bitcoin sold.

Mining bitcoins requires electricity

A network of fast computers that utilize plenty of energy is employed within the bitcoin mining process.

In keeping with the University of Cambridge Power Consumption Index, if the bitcoin system were a nation, it might be the 34th largest electricity user, prior to the Philippines and behind European country.

Elon Musk, the CEO of Tesla, said in May 2021 that the automaker would stop accepting bitcoin unless that cryptocurrency found a method to reduce its carbon impact. Other blockchains’ creators have proposed less energy-intensive alternatives.

Blockchain in bitcoin moves slowly

Approximately seven new transactions could also be added to the bitcoin blockchain per second. Visa, the market leader in credit cards, claims that it can process 24,000 transactions per second.

The bitcoin system now faces a scalability problem as a result. On this issue, several blockchain-based cryptocurrencies are working.

The much-anticipated Ethereum 2.0 system upgrade is expected to increase the current transaction rate of 30 transactions per second to 10,000 transactions per second.

Future of Blockchain technology

There are dozens other cryptocurrencies that are supported blockchain technology, whether or not the Bitcoin system is its most well-known use.

While it’s yet unclear if bitcoin are going to be able to replace other kinds of conventional payment systems, blockchain technology applications are expanding quickly, and supporters believe that they might bring about substantial improvements in a wide range of industries.

However, I guess that you are now clear about how to become a blockchain developer as well as some general queries about blockchain.

Now, its time to share your thoughts and experience about this trending technology and how to become a blockchain developer.
