Blockchain technology, invented in 2008, is a decentralized, encrypted digital ledger used to record transactions securely and reliably without the need for intermediaries like banks. This technology functions as a distributed ledger shared among all network participants, where transactions are linked together in "blocks" via unique cryptographic codes (hashes), making any attempt to alter or delete data extremely difficult. Millions of devices worldwide (the mining process) verify transactions before they are added to the chain, providing high security and preventing tampering. Key advantages of this technology include immutability, complete transparency, high availability, and robust data protection. Blockchain types vary to include public (like Bitcoin), private, and hybrid (consortium) networks, allowing for diverse applications. Experts expect this technology to be a gateway to a vast world of innovation and to fundamentally change business methods, especially in sectors such as money transfers.
