Topics discussed

Bitcoin’s origins

The session used Satoshi Nakamoto and HBO’s Money Electric as discussion prompts about Bitcoin’s origins and the uncertainty around its creator’s identity.

A shared-record analogy

The presentation compares a blockchain to a shared digital notebook whose entries cannot simply be erased or changed. This introductory analogy helps explain a record maintained across a network.

Ethereum and Web3

The slides introduced Ethereum and a blockchain-enabled internet. The meeting trivia developed those ideas through Ether, smart contracts, decentralized applications, and the goal of giving users greater control over their data.
