Can I Learn Blockchain As My First Language

Solidity, Blockchain, and Smart Contract Course â Beginner to Expert Python Tutorial

Yes, you can learn blockchain as your first language. I highly recommend this because its the most efficient and effective way to learn. You will certainly need to add more skills to your toolbelt in the long term, but I advocate for learning these things on an as-needed basis while you specialize in blockchain development.

What Is A Block

A Blockchain is a chain of blocks that contain information. The data which is stored inside a block depends on the type of blockchain.

For Example, A Bitcoin Block contains information about the Sender, Receiver, number of bitcoins to be transferred.

Bitcoin Block

The first block in the chain is called the Genesis block. Each new block in the chain is linked to the previous block.

The Book Of Satoshi By Phil Champagne


Blockchain technology and Bitcoin are linked because blockchain made cryptocurrencies possible. This book offers the writings of the mysterious creator of Bitcoin, known as Satoshi Nakamoto. As of early 2020, the general public still did not know the true identity of Nakamoto.

The Nakamoto persona has only a virtual existence, much like its cryptocurrency creation. The persona is present only in the online publications Nakamoto offered to explain Bitcoin during the earliest days of its introduction. The Book of Satoshi is a definitive collection of Nakamoto’s essential writings, including the original paper detailing the idea of Bitcoin. The book also contains Nakamoto’s explanation of how Bitcoin works and a chronologically organized collection of emails and online forum posts by Nakamoto.

What Is A Blockchain

A blockchain is a permanent, sequential list of transaction records distributed over a network. Each block in the chain contains a hash of the previous block, along with a timestamp and transaction data. This makes the blockchain inherently resistant to attack or manipulation.

Blockchain technology is ideal for recording various types of transactions where data is sensitive or targeted by hackers for unauthorized duplication or other fraudulent activity. Bitcoin and other cryptocurrencies use blockchain technology to record transactions. Blockchain for business applications can include recording of contracts, medical records, monetary transactions and much more.

Disruption Of Different Sectors

The first industry to be disrupted is the banking sector. In reality, blockchain can offer a secure way to store all the records of the banks. More so, it can also offer a cheaper and faster way to transfer all the money without any help from a centralized authority.

In healthcare, it can allow healthcare providers and doctors to access patient information in a secure way without harming their privacy. Moreover, it can also stop counterfeit drug issue thats been ravaging this industry form the inside.

For the supply chain, it can offer real-time tracking and monitoring of all the production lines and supplies. It can also offer a more efficient process of trading with another company.

With blockchains help, there would be no form of corruption in politics anymore. Governments can securely store confidential information of the public without any thefts.

More so, the tech can simplify the process of real estate and insurance companies. In reality, doing the process in the system would get rid of all the unnecessary paperwork load.

On the other hand, legal firms can use the tech to offer provenance of any evidence of documentations. You can easily prove your inheritance right digitally, as well.

For the IT sector, blockchain can offer a secure and immutable system that no hackers can get access to. Additionally, it can also secure cloud service providers as well. Intellectual property rights management is another plus point, giving artists the value they all deserve.

How Does It Work

  • Each transaction gets recorded as a data block: The transactions display the asset movement, and the block carries information of an asset.
  • Each block connects with the next one in a chain: data blocks form a data chain as the asset moves places. The blocks also confirm the sequence and time of transactions accurately while linking with one another to prevent alteration or insertion of a new block between existing blocks.
  • Transactions block together, forming an irreversible data chain or Blockchain. Here, every additional block provides better strength to the previous blocks verification and for the whole Blockchain itself.

It makes the chain immutable and declines the possibility of malicious activities from entering into the ledger. Thus, it builds a secure network with greater transparency that members could trust.

How To Transition To A Blockchain Career

To transition into a career in blockchain, the first step anyone would need to take is to pick the initial technology they want to work on, Horvat said. That can range from contributing to a core of open-sourced blockchains creating business networks using the Hyperledger family of modular platforms or creating public smart contracts using Solidity.

“Having experience with back-end and lower level development is beneficial for the transition as well, but is not required,” Horvat said.

Toptal sets a high bar for talent, requiring engineers to have a strong fundamental knowledge of blockchain and the underlying technologies including cryptography and distributed systems as well as some knowledge of how most public blockchains work, “which we test for using theoretical tests and coding tasks which are geared towards the technologies powering blockchains.”

Blockchain developer positions come in all types, from hourly to full-time. The type of role depends on the size of the client and the kind of project or product it is working on, according to Horvat. Regardless, the demand for blockchain roles is skyrocketing.

Toptal’s client list ranges from startups raising funds via ICOs to Fortune 100 companies that are transferring major business segments to blockchain, Horvat said. The work developers are tackling varies from distributed programming to cryptography, private blockchains, decentralized applications and smart contracts, among others.
