This process is secured by a consensus mechanism called Proof of Work (PoW), which requires participants to solve complex computational problems. The first to solve the problem gets to add the next block to the chain, earning newly minted Bitcoins as a reward.

Nodes: Network computers that maintain and update the blockchain.
Blocks: Bundles of verified transactions added to the chain.
Proof of Work: A consensus mechanism that secures the blockchain.

2. Who Invented the Underlying Technology for Bitcoin’s Blockchain?

While Bitcoin was the first to implement blockchain technology, the foundational concepts date back to the early 1990s with the work of Stuart Haber and W. Scott Stornetta. They introduced a cryptographically secured chain of blocks. Their early work laid the foundation for blockchain technology. Later, Nick Szabo conceptualized “bit gold,” a decentralized digital currency, further contributing to the evolution of blockchain principles.

Stuart Haber and W. Scott Stornetta (1991): Proposed a cryptographically secured chain of blocks.
Nick Szabo (1998): Developed the concept of “bit gold,” a precursor to modern cryptocurrencies.
