What Is Blockchain?
Blockchain is a digital ledger that records transactions in a secure, transparent, and tamper-proof way. Instead of storing data on a single server, blockchain distributes it across a network of computers. Each transaction is added as a block and linked in a chain, making it almost impossible to alter without detection.
Blockchain is not limited to cryptocurrencies — it supports smart contracts, identity management, logistics, finance, and more.
What Is the Current Size of the Blockchain Market in 2025?
As of 2025, the global blockchain market is valued at approximately $125 billion, driven by enterprise adoption, crypto transactions, and decentralized applications.
It has grown over 40x since 2020, making it one of the fastest-growing technology sectors worldwide.
