What is Blockchain Technology?
Blockchain technology is a digital ledger that records transactions across many computers. It’s different from traditional databases because it’s hard to change the data. This makes it a secure way to record transactions and track digital assets.
Understanding the Fundamentals of Blockchain
A blockchain is a digital ledger of all cryptocurrency transactions. It’s a decentralized network, not controlled by any single entity. This technology lets businesses make secure transactions without needing third parties.
Network nodes verify transactions and record them in a public ledger called a blockchain.
The key features of blockchain technology include:
- Decentralization: Blockchain networks are decentralized, eliminating the need for a central authority to oversee or manage the system.
- Transparency: All transactions are recorded in a public ledger, making the system transparent and traceable.
- Immutability: Once a transaction is recorded, it cannot be altered or deleted, ensuring the integrity of the data.
- Security: Blockchain uses cryptographic hash functions to secure the network, making it extremely difficult to tamper with the data.
Blockchain technology has the potential to disrupt various industries. It can change finance, supply chain management, healthcare, and real estate. It enables the development of decentralized applications (dApps), cryptocurrencies, and other innovative solutions.
