Difference between Blockchain and Database
A blockchain is a type of distributed ledger technology that facilitates peer-to-peer communication and enables peers to collaborate on the creation of a decentralized, unified network through the use of an algorithm called a consensus algorithm.
Blockchain, which is a distributed ledger technology, has been meticulously designed to be resistant to modification and tampering as a result of its stringent design. The blockchain is distributed across each node, and each node stores its own copy of the blockchain to ensure that the network continues to function properly and remains secure. Because of this, a blockchain can operate globally without borders and is resistant to censorship.
In contrast to blockchains, the database uses a centralized ledger that is managed by an administrator. Only a reliable, centralized authority has access to the database, making it possible to read and write, which is one of the features that sets the database apart from others.
The fact that it is centralized results in many positive aspects, including the fact that it is simple to administer and swift in its operations. In spite of all of these advantages, there are a few disadvantages, one of which is the fact that the entire collection of data can be altered by the individual who controls the database itself.
Blockchain vs. Database in Terms of Authority
Blockchain is decentralized; there is no administrator or centralized approach. However, hybrid blockchains are permitted and give the organization the complete authority to modify their setup according to requirements because complete decentralization cannot be implemented in businesses with confidential data.
The database is allocated to the administrator with complete authority to modify, manage, or control the data the way he wants. Another task, such as performance optimization, can be done by him because, with time, larger databases become slow.
Blockchain vs. Database in Terms of Architecture
Blockchains use a distributed ledger network architecture in which each peer is connected through cryptographic protocols. Nodes collectively take part in the consensus algorithm.
The database is based on a client-server architecture. Both types of environments—small scale as well as large scale—are suitable for it and are completely dependent on a centralized approach.
Blockchain vs. Database in Terms of Immutability and Data Handling
In blockchain, data once entered cannot be erased, modified, or replaced. This means that data is immutable. The database works on the principle of CRUD, which stands for creating, reading, updating, and deleting, which means new data can be entered or existing data can be modified when necessary.
Blockchain vs. Database in Terms of Transparency
Blockchain data is much more transparent because the data, once written in public blockchains, is readily available to everyone who has the right tools to verify it.
The database is not transparent because only higher authorities have the right to access it.
Blockchain vs. Database in Terms of Speed and Performance
Blockchain is slower in executing operations as it is a modern technology and will take time to match up with old-age technologies such as databases.
The database is faster in execution time and can handle millions of data points at once without any lag.
Conclusion on Blockchain vs. Database
Both blockchains and databases have pros and cons. The database should be selected when speedy execution is needed and business processes need to be supported and scaled at the same time.
Blockchain should be selected when accuracy, transparency, and trust are priorities.
