Blockchain technology is one of the most hyped innovations of the 21st century. Blockchains, which were developed to support bitcoin, blockchains now power thousands of cryptocurrencies, and developers are working on integrating the technology into businesses, including medicine, art, and finance.

What is Blockchain Technology?

A blockchain is a data record that is distributed across a network of computers, meaning there is no single point of failure.  

Blockchains are digital ledgers of transactions maintained by a network of computers in such a way that they can’t be hacked or altered. By using the technology, individuals can deal directly with one another without being mediated by a third party, such as a government, a bank, or another third party.

Advantages of blockchain

Transparency

A public blockchain uses open-source code, accessible to virtually anyone who has the necessary equipment. The technology of the blocks themselves, which are permanently linked together on a chain, permits greater visibility for all involved, which can aid peer-to-peer verification and help prevent fraud.

Cost efficiency

In traditional transactions such as using credit cards to make payments, users typically pay a fee. Eliminating third-party verification means lower costs per transaction. The use of smart contracts potentially reduces time costs as well as actual fees.

Accuracy

By using thousands of computers on the blockchain network to confirm and validate transactions, the potential for human error is all but eliminated. This leads to greater accuracy in the recording of data.

Helps prevent hacks

Decentralization makes it harder to tamper with any particular block of data, because all data is secured using peer-to-peer verification, rather than a central authority. This self-policing, so to say, contributes to the security of the blockchain.

Financial alternative

Blockchain potentially provides a banking alternative for those who are unbanked (a common problem in many developing nations), and a way to secure personal information for citizens of countries with unstable governments.

Disadvantages of blockchain

Sustainability issues

Because blockchain relies on vast networks of super-powerful computers for almost any function (e.g. mining cryptocurrency), the technology typically uses significant amounts of energy that many believe can be harmful to the environment. In particular, crypto mining that relies on a “proof of work” system is particularly inefficient, using quantities of energy comparable to some countries.

Speed bumps

Although blockchain can speed up transactions, it may not be as fast as legacy systems (like credit cards), which can process thousands of transactions per second.

Illicit activity

The security and privacy that are hallmarks of blockchain technology cut both ways, in effect, as both legal and illegal activity can take advantage of these features. Indeed, blockchain has a history of being used as part of illegal networks like Silk Road, considered part of the dark web.

How Does Blockchain Technology Work?

The Blockchain is now in the mainstream because of its disseminated ledger expertise, which means it can record any sort of transaction or data digitally, which is of valued importance. It will help to rescue your business from all its complex problems and give it top-notch security. 

From smart contracts to DApps, our blockchain development services render one-of-a-kind systems that leverage the unique features of blockchain and deliver solutions beyond expectations. Clients from diverse industries have been taking advantage of our expertise to achieve their objectives.

The blockchain is a combination of three technologies:

  • Cryptographic keys
  • A peer-to-peer network containing a shared ledger
  • A means of computing, to store the transactions and records of the network

Cryptography keys consist of two keys – a private key and a public key. They facilitate successful transactions between two parties. The two keys are used by each individual to establish a secure digital identity reference. This secure identity is the most important aspect of Blockchain technology. This identity is known as a ‘digital signature’ in the world of cryptocurrency and is used to authorize and control transactions.

There are four types of blockchains

  • Private Blockchain Networks
  • Public Blockchain Networks
  • Permissioned Blockchain Networks
  • Consortium Blockchains

Private Blockchain Networks:

A private blockchain, also known as a managed blockchain, is controlled by a single organization.  In a private blockchain, the central authority determines who can be a node.

Public Blockchain Networks:

Public blockchains are permissionless in nature, allow anyone to join, and are completely decentralized. Public blockchains allow all nodes of the blockchain to have equal rights to access the blockchain, create new blocks of data, and validate blocks of data.

Permissioned Blockchain Networks:

Permissioned blockchains are distributed ledgers that are not publicly available. It can only be accessed by users with permissions. The users can only perform specific actions granted to them by the ledger administrators and are required to identify themselves through certificates or other digital means

Consortium Blockchains:

Consortium blockchain offers the new kid on the block to join the established structure and share information instead of starting from scratch. This technology helps organizations to find solutions together and save time and development costs. Consortium blockchains are also known as Federated blockchains.
