Blockchain Technology: Key Features & Security Architecture

Blockchain technology refers to a decentralized database system containing cryptographically linked blocks of digital assets. It is a peer-to-peer network database ruled by a decentralized system. It represents a sequential shift away from the conventional agents towards transparent conduct.

With blockchain technology, industries have been transformed simultaneously in all dimensions, most notably in how businesses operate on a day-to-day basis. Blockchain integration in business solutions also cuts out intermediaries’ role across various vital services and reduces overheads.

Blockchains are secured through multiple mechanisms, including advanced cryptographic techniques, logical models, and many more.

This article explores techniques that make blockchains secure.

Blockchain Security: Centralized Blocks

The term ‘Blockchain Technologyrefers to a centralized digital blockchain that contains money transactions. It consists of cryptographic blocks that are interconnected to each other. Blockchain solutions are designed to be tamper-proof and highly secure.

Blockchain consists of three key strategies: Cryptography, Decentralization, and Consensus.

All of these features make it difficult for tampering with a blockchain record. It is because the hacker would be required to change the entire block containing the blockchain records. The network participants also have their security keys assigned to the ultimate transactional key that acts as a personalized digital signature.

In any circumstance, if the record is altered, the digital signature will get invalid, and any attack will be detected immediately by the corresponding network.

Early notifications and alerts are essential for preventing further damages or attacks in blockchains. At a glance, blockchain security also provides various desirable features that help to secure transaction data.

Key Characteristics of Blockchain Security

Unquestionably, blockchain is a means to ensure security. It has become a disruptive technology due to its ability to centralize, incentivize, digitize, and secure the transactions’ validation. The records are protected through cryptography decentralization to ensure the foolproof blockchain security of the blocks. 

Many sectors are evaluating blockchain technology for detecting the strategic differentiation to leverage their business potential. Blockchain has the potential to simplify business processes and give them access to enhanced performance and security.

Every transaction in this technology that gets recorded and stored is not directly labeled as a blockchain.

Some of the defining characteristics of blockchain technology are as follows:


In blockchain technology, all transactions are immutable. Even the code encryption is used for the transactions, effectively securing the participants’ date, time, and information.


Blockchain technology executes transactions only when the parties participating in the network anonymously approve them. One may even choose to alter the consensus-based regulations to match the circumstances.


With distributed blockchain technology, the processing is distributed evenly among all business peers, building a shared infrastructure within the business system. Participants can independently validate the details without any centralized authority.

Digital Signature

Blockchain technology streamlines the exchange of translational values by using unique digital signatures that are based on public keys. In blockchain technology, private key codes are known only to the key owners to develop ownership proof. It is a critical feature that avoids any fraud in blockchain record management.


An invalid transaction is detected by consensus-based blockchain technology. When transactions are integrated into a blockchain ledger, it is not easy to roll them back. Cryptographically, blockchain blocks are created and sealed inside the chain, making it difficult for the hackers to edit or delete already developed blocks and put them on the network.

The Security Architecture of Blockchain Technology

Blockchain records are protected by cryptography, in which network users have their own private and secure keys. This key is attached directly to the transaction keys, and it functions as a customized digital signature. Blockchain safeguards and prevents any malicious attack and secures the data of the company by encrypting it.

Blockchain is empowered at many layers for developing any enterprise application.

These layers include the following elements:

  • User access layer
  • Presentation layer
  • Identity and access management layer
  • Application layer
  • Network layer
  • Infrastructure layer

Blockchain technology is specially designed to pay off in the long run. Blockchain professionals can help you implement the essential measures to ensure the success of your blockchain solution. Blockchain has irreversible and highly encrypted data blocks that allow us to fight against any fraudulent conduct.


Blockchain Technology has shown its potential for conventional transformer industries with its key attributes like persistence, decentralization, audibility, etc. Blockchain offers highly enhanced security during transactions irrespective of its value. The security of blockchains makes it a highly unique and universal solution to streamline legal contracts and ensure Enterprise transparency.
