Satoshi Nakamoto remained active in the community until April 2011, then disappeared from public view, leaving the project to be developed by the open-source community.
What was the first cryptocurrency transaction?
The first Bitcoin transaction occurred on January 12, 2009, when Satoshi Nakamoto sent 10 BTC to Hal Finney, a computer scientist and early Bitcoin contributor. The first commercial transaction happened on May 22, 2010, when two pizzas were purchased for 10,000 BTC (worth about $41 at the time, but would be worth hundreds of millions today).
What was the ICO boom?
The ICO (Initial Coin Offering) boom occurred in 2017-2018 when projects raised over $6 billion by selling tokens to investors. This democratized fundraising but led to many scams and failed projects. The boom ended with the "crypto winter" of 2018-2020, during which developers focused on building infrastructure and improving technology.
What is DeFi summer?
DeFi summer refers to the explosive growth of decentralized finance in 2020-2021, when Total Value Locked (TVL) grew from $1 billion to over $100 billion. This period saw the rise of yield farming, governance tokens, DAOs, and DEX trading. It also marked the beginning of significant institutional adoption of cryptocurrencies.
How has cryptocurrency evolved over time?
Cryptocurrency has evolved from Bitcoin's simple peer-to-peer electronic cash system to a complex ecosystem including smart contracts (Ethereum), DeFi protocols, NFTs, Layer 2 scaling solutions, and institutional infrastructure.
