Blockchain technology overview

Blockchain is like a digital ledger that stores transactions across a network of computers. These transactions are grouped into blocks linked together in a chain. Each block contains a list of transactions, a timestamp, and a unique cryptographic hash that links it to the previous block. This chain structure creates a chronological and tamper-resistant record of transactions.

The key features of blockchain technology are:

  • Decentralization - Unlike traditional centralized systems where a single authority controls the data, blockchain operates on a decentralized network of computers (nodes). This decentralization distributes control among participants, reducing the risk of single points of failure or manipulation.
  • Immutability - Once a transaction is recorded on the blockchain, it cannot be altered or deleted. Each block contains a cryptographic hash of the previous block, creating a chain of immutable records. This ensures the integrity and permanence of the data.
  • Transparency - Blockchain transactions are visible to all network participants. Anyone can view the entire transaction history, promoting transparency and accountability. However, while transactions are transparent, the identities of the parties involved can remain pseudonymous, enhancing privacy.

Blockchain uses cryptographic techniques to secure transactions and ensure trust in the network. Each transaction is verified and validated by multiple nodes in the network through a process called consensus. Once consensus is reached, the transaction is added to the blockchain, making it virtually impossible to alter without consensus from the most nodes.

Additionally, blockchain employs public-key cryptography to authenticate participants and ensure secure communication. Each participant has a unique cryptographic key pair consisting of a public key (used for encryption and verification) and a private key (used for decryption and signing). This cryptographic security mechanism ensures that only authorized parties can access and transact on the blockchain, enhancing security and trust.

Non-cryptocurrency applications

Blockchain's non-cryptocurrency applications extend beyond finance, leveraging its core features to revolutionize industries. From supply chain management to healthcare, blockchain enhances efficiency, security, and trust.
