Definition and History
Blockchain is a distributed database that records information in a way that it cannot be easily altered or deleted. First introduced in 2008 as the technology behind Bitcoin by an individual or group using the pseudonym Satoshi Nakamoto, blockchain has ushered in a new era of secure and transparent data recording and storage.
Technology and Operating Mechanism
Blockchain technology operates on a data structure called "blocks," each containing information about a certain number of transactions and linked together using cryptography. Each new block added to the chain must be verified by a network of computers participating in the system. This ensures that every transaction is recorded publicly and cannot be altered.
Benefits and Challenges
Blockchain offers numerous benefits, such as enhanced security, transparency, and reduced transaction costs. However, it also faces challenges such as scalability, slow transaction speeds, and a lack of public understanding of the technology.
