What is blockchain technology?

Blockchain technology is an Avant-grade database mechanism of a shared, unchangeable ledger technology to record transactions, track assets and ensure trust. Unwrap why businesses worldwide are embracing it.

Blockchain Outline

Blockchain explained : Blockchain is a distributed database or immutable ledger connected to various nodes of a computer network. As this is a database, blockchain stores information in a digital form. Blockchain has an integral role in cryptocurrency systems that aid in tracking assets, which may be either tangible assets (car, house, cash, or land) or intangible assets (property, copyrights, branding, etc). In Blockchain, transactions can be done without the interference of central authority also with low ris

Why blockchain is undeniable

Usually, every business is information-driven. Blockchain assures speedy and authentic transactions also it provides an immediate, shared, transparent, and flawless transaction experience, on the unchangeable ledger technology. In a blockchain network, one can track payments, accounts, orders, and more and can also view the entire details of transactions that ensure trust among users. Blockchain is undeniable as it unlocks new efficiencies and opportunities.

Key elements of a blockchain

Distributed ledger technology

It is a technical infrastructure or protocol that ensures secure transactions by eliminating third parties. It is authorizes concurrent access, validation, and recording in an unchangeable manner across the Blockchain network.

Immutable records

Once it is recorded in the shared ledger, no one can alter the transaction database. If the transaction commits any error, then a new transaction needs to be added to change the error, and both transactions are visible.

Smart contracts

The smart contract system with the set of rules on the blockchain ensures speedy transactions. A smart contract can define conditions for corporate bond transfers incorporating the payment of travel insurance and more.

How blockchain works

01

Transactions recorded as a block of data

Blockchain records transactions as a block of data, and each block contains a hash value. The blocks are interconnected with each other and not altered by anyone, ensuring the blockchain is tamperproof.

02

Each block is interconnected

The blocks here create a 'chain of data' while an asset moves over many hands. The block registers the accurate timing and sequence of the transactions, and the blocks are linked securely between two existing blocks

03

Transactions are connected in an unchangeable chain

Each newly added block supports the verification of the last block. This makes the blockchain tamper-proof and removes the probability of tampering in turn, builds a trustable network.

Benefits of blockchain

Greater trust

Blockchain network ensures greater trust as it is an immutable ledger, accessed only by the members who are granted access. This trust is built by high-level security, transparency, and traceability.

Greater security

Blockchain is said to be an "unhackable" technology. Data accuracy is required from all network members to make the blockchain an immutable network as it is recorded permanently.

More efficiencies

As it is a distributed ledger shared among the members of the network, eliminates the time-wasting record settlement. To speed up transactions, it has a set of rules called a smart contract

Types of blockchain networks

There are various ways to build a blockchain network. They can be built as public, private, permissioned, or by a consortium.

Public blockchain

Public blockchains use computers connected to the public internet and bundle into blocks and it relies on the principle of obscurity. A public blockchain is not suitable for enterprises concerned about the confidentiality of information carried through the network.

Private blockchain networks

A private blockchain network is the same as a decentralized public blockchain network where one organization governs the network and controls who are allowed to participate, executes a concord protocol, and maintains the shared ledger in turn fosters trust among participants.

Permissioned blockchain networks

Businesses that employ private blockchains usually set up a permissioned blockchain network as a public blockchain network can also be a permissioned blockchain. Permissioned blockchain limits who is permitted in the network and in what transactions. Participants require an invitation or permission to join the network.

Consortium blockchains

The authority and maintenance of this blockchain lean on multiple organizations. These previously selected organizations have the control to choose who may propose transactions or access the data. A consortium blockchain is suitable for businesses where all the participants need their blockchain to be permissioned.

Blockchain Security

It is crucial to have a complete security strategy that employs cybersecurity frameworks and assured services and the best approaches to make blockchain resistant to cyber-attacks and frauds. Blockchain security is based on the principles of decentralization, cryptography, and consensus that guarantees trust among the users.
