Blockchain technology was first introduced in 2008 as the foundation for Bitcoin, a decentralized digital currency. It was conceptualized by an anonymous individual or group operating under the pseudonym Satoshi Nakamoto (YouTube, Wiki). The primary goal was to create a transparent, immutable, and decentralized ledger system that eliminated the need for traditional intermediaries like banks.
The Bitcoin network, launched in 2009, marked the first practical implementation of blockchain technology. It showcased blockchain's ability to securely facilitate financial transactions without relying on centralized authorities, proving the technology's robustness and potential.
As blockchain technology gained recognition, its applications began to expand beyond cryptocurrencies. Industries such as supply chain management, healthcare, and finance explored how blockchain could enhance security, transparency, and efficiency in recording and tracking information.
Throughout its evolution, blockchain's core attributes—decentralization, immutability, and transparency—were emphasized. These characteristics addressed trust issues in digital transactions and opened the door for its application in various fields.
