What Makes Blockchain Secure: Key Characteristics & Security Architecture

What Makes Blockchain Secure?

A blockchain, as the name implies, is a chain of digital blocks that contain records of transactions. Each block is connected to all the blocks before and after it. This makes it difficult to tamper with a single record because a hacker would need to change the block containing that record as well as those linked to it to avoid detection. This alone might not seem like much of deterrence, but blockchain has some other inherent characteristics that provide additional means of security.

The records on a blockchain are secured through cryptography. Network participants have their own private keys that are assigned to the transactions they make and act as a personal digital signature. If a record is altered, the signature will become invalid and the peer network will know right away that something has happened. Early notification is crucial to preventing further damage.

Key Characteristics Of Blockchain Security

Blockchain technology comes with many built-in features that appeal to objectives like cryptocurrency transactions, land records, and many more. The protection of confidential data is a determinant factor for users.

Blockchain is undeniably a measure that ensures 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.

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

·        Distributed

·        Immutable

·        Consensuses Based

·        Digital Signatures

·        Persistent

The Security Architecture In The Blockchain Technology

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 has presented its potential for conventional transformer industries with its key features like- persistence, decentralization, audibility, etc.
