What is Blockchain?
Blockchain is a distributed ledger system that provides a secure and transparent way to record transactions and data across a network of computers. It was invented in 2008 by Satoshi Nakamoto as a way to enable secure, decentralized transactions without the need for a central authority to verify them. The basic idea behind blockchain technology is that transactions are recorded in blocks, which are then added to a chain of other blocks to create an immutable record of all the transactions that have taken place.
Benefits of Blockchain
The benefits of blockchain technology are numerous, including increased security, transparency, and efficiency. Because transactions on a blockchain are distributed across a network of computers, they are much less vulnerable to attack or manipulation than traditional centralized systems. Additionally, the transparency of a blockchain allows for greater accountability, as every transaction is recorded and can be traced back to its point of origin. Finally, the efficiency of a blockchain enables faster and cheaper transactions, making it an ideal platform for everything from financial transactions to supply chain management.
