What’s More Secure: Blockchain Or Database? – Analytics India Magazine


Data storage options database and blockchain are architecturally different and come with their own sets of advantages, vulnerabilities, and challenges. 

On the one hand, database storage is based on client-server-based architecture and can function in small and large scale environments. Under database storage, the client acts as a receiver, and servers– the data storage place– acts as a Central Processing Unit. Firewalls and anti-malware software secure every kind of communication and data exchange between clients and servers.

On the other hand, blockchain storage is in complete contrast to the server-based model of a database. It is decentralised storage based on a peer-to-peer network of a distributed ledger. Data is stored in public or private blockchain in blocks that are secured by cryptographic hash.

Control in database 

Every aspect of the database is controlled by an administrator and is highly centralised. It is also designed like a hybrid blockchain but is not nearly identical to a public blockchain. 

Blockchain is a digital ledger that stores information permanently in data structures called blocks. It keeps track of data in uniform-sized blocks, and each block stores the hashed information from the previous block. These blocks are secured by cryptographic security. Blockchain uses hashing algorithms to secure transactions. The most common hashing algorithm– SHA256, is used by US’s National Security Agency (NSA)-developed Bitcoin. The hashed information is data and digital signature from the previous block. The hashes of the previous
