What Is Blockchain? And Why Does It Matter?

In the past, there have been numerous attempts to establish digital money, but they have all been unsuccessful. This issue was addressed in the creation of Bitcoin by utilizing a particular kind of database known as a blockchain. The majority of common databases, such as SQL databases, contain a manager who can alter the entries. Because its users run it, blockchain is unique in that no one is in charge.

Information is essential to business. It is ideal if it is quickly and precisely received. Because it offers real-time, shareable, and completely transparent data that is kept on an immutable ledger and only accessible to members of a permission network, blockchain is the best technology for delivering that information. These are all about what is blockchain.

What Is Exactly Blockchain?

Blockchain is a decentralized, unchangeable database that streamlines asset tracking and transaction recording within a business network. An asset could be material (like a house, car, cash, or piece of land) or immaterial (intellectual property, patents, copyrights, branding). Practically anything of value can be recorded and traded on a blockchain network, reducing risk and boosting efficiency for all parties.

A blockchain’s innovation is that by guaranteeing the accuracy and security of a data record, it promotes confidence without the need for a trustworthy third party.

How Does a Blockchain Work?

Blockchain aims to make unaltered digital information distribution and recording possible. A blockchain is composed of immutable ledgers, or records of transactions, which cannot be changed, deleted, or destroyed. Blockchains are therefore also referred to as distributed ledger technologies (DLT).

Each transaction in this case is captured as a “block” of data as it occurs. These transactions show the transfer of an asset, which could be an intangible asset or a tangible product (intellectual). The data block can be used to store information about who, what, when, where, how much, and even the condition, like the temperature of a food shipment.

There are connections between every block and the ones that came before it and after it. These blocks form a chain of data as an asset is transferred between locations or ownership changes. The blocks securely link together to prevent any blocks from being altered or a block from being inserted between two already existing blocks, and they confirm the precise timing and order of transactions.

A blockchain is a block-joined, unbreakable chain of transactions. Every new block improves the veracity of the previous block and, consequently, the blockchain as a whole. This makes the blockchain tamper-evident and gives it its essential strength of immutability. By doing this, you and other network participants can establish a reliable ledger of transactions and take away the opportunity for malicious actors to tamper with the data.

Advantages of Blockchain

Operations frequently waste time and money on third-party validations and duplicate record keeping. Records management software may be vulnerable to online fraud and attacks. Lack of transparency may slow down the verification of data. And since the Internet of Things was developed, the volume of transactions has increased. All of this slows down business and hurts the bottom line, so we need a better solution.

KeyPoint’s advantages are

  • Greater trust
  • Greater security
  • More efficiencies
  • Accuracy of the Chain
  • Cost Reductions
  • Decentralization
  • Efficient Transactions
  • Private Transactions
  • Secure Transactions
  • Transparency
  • Banking the Unbanked

Is Blockchain Safe?

Decentralized security and trust are made possible by blockchain technology in many different ways. New blocks are always initially stored in a linear and chronological order. To put it another way, they are continuously added to the blockchain’s “end”. After a block has been added to the blockchain, it is very difficult to change its contents without the support of the majority of the network. This is because each block has a timestamp, its own hash, the hash of the block that came before it, and other information. Hash codes are created by a mathematical operation that takes a digital piece of information and turns it into a string of numbers and letters. The hash code also changes if the data is altered in any way.

Blockchain vs Bitcoin

The idea of blockchain technology was first put forth in 1991 by two researchers named Stuart Haber and W. Scott Stornetta who were interested in implementing a system where document timestamps could not be changed. But blockchain didn’t have its first practical use until almost two decades later, with the introduction of Bitcoin in January 2009.

On a blockchain, the Bitcoin protocol is constructed. Bitcoin’s anonymous founder, Satoshi Nakamoto, described the digital currency as “a new electronic cash system that’s fully peer-to-peer, with no trusted third party,” in a research paper that introduced it.

It’s important to note that blockchain is only used by Bitcoin to immutably record a ledger of payments in a transparent manner. In theory, however, blockchain could be used to immutably record any number of data points. This could take the form of transactions, votes in elections, product inventories, state identifications, deeds to homes, and much more, as was previously mentioned.


  • A blockchain is a particular kind of shared database that differs from other databases in that it stores data in blocks that are then connected by cryptography.
  • Each new data point results in the creation of a new block. The data are chained together in chronological order once the block has been filled with information and is attached to the block before it.
  • Although different kinds of information can be stored on a blockchain, a transaction ledger has so far been its most popular use.
  • Blockchain is utilized in the context of Bitcoin in a decentralized manner, ensuring that no one user or group has control but rather that all users collectively maintain control.
  • Since decentralized blockchains are immutable, the data entered into them cannot be changed. This implies that Bitcoin transactions are permanently recorded and visible to the public.
