The Bitcoin symbol is white and placed in the center of a circular background that transitions from gold in the middle to a gray border. The symbol is depicted as a person with a black blindfold, extending an arm to touch a black silhouette of a guide dog on the left. The other arm is holding a white cane with a red tip on the right.

Introduction to Blockchain

This section has information about blockchain development and technology.

History of Blockchain Technology

Early Foundations (1970s-2000s)

The concept of public key cryptography was introduced by Whitfield Diffie and Martin Hellman in 1976, laying the groundwork for secure communications.

In 1991, Stuart Haber and W. Scott Stornetta proposed a system for timestamps to ensure the integrity of digital documents, which is an early form of blockchain.####

Emergence of Cryptocurrencies (2008-2010)

In 2008, an individual or group using the pseudonym Satoshi Nakamoto published the Bitcoin white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System." This paper outlined a decentralized digital currency that operates without a central authority.

The Bitcoin network was launched in 2009, and the first block, known as the "genesis block," was mined by Nakamoto. Bitcoin introduced the concepts of blockchain as a distributed ledger and mining as a consensus mechanism.

Growth and Innovation (2011-2015)

Other cryptocurrencies, such as Litecoin, were introduced in 2011, featuring faster transaction times and different hashing algorithms.

Vitalik Buterin proposed Ethereum in 2013, a platform that allows developers to create decentralized applications (dApps) and smart contracts, expanding the use of blockchain beyond currency.

Ethereum was launched in 2015, introducing the concept of programmable blockchain. This allowed for complex transactions and applications beyond simple currency transfers.
