Blockchain technology is a decentralized and distributed digital ledger that records transactions across multiple computers. It was originally designed as the underlying technology for cryptocurrencies like Bitcoin, but its applications have expanded beyond finance to various industries like supply chain management, healthcare, real estate, and more. The fundamental concept behind blockchain is to create a secure and tamper-resistant record of transactions or data.
Here's a brief overview of how blockchain works:
Decentralization:
Unlike traditional centralized systems where a single entity controls the data, blockchain operates on a decentralized network of computers (nodes). Each node stores a copy of the entire blockchain, ensuring that no single point of failure exists.
Transactions:
Transactions are grouped into blocks. Each block contains a set of transactions along with a unique identifier called a hash. The hash of each block is based on the data in the block and the hash of the previous block, creating a chronological chain of blocks.
Consensus Mechanism:
Before a new block is added to the chain, the network must agree that it is valid. This is achieved through various consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS), where nodes perform calculations or stake assets to validate transactions.
Immutability:
Once a block is added to the blockchain, it is extremely difficult to alter the information within it. This is because changing the data in one block would require changing the data in all subsequent blocks, which would require the consensus of the majority of the network, making it highly secure against tampering.
Security:
The decentralized and cryptographic nature of blockchain ensures high security. Transactions are verified through complex mathematical algorithms, and private keys are used to authenticate users and control access.
