Ethereum Blockchain Technology
summary
Ethereum is presented as an open platform for programmable money and smart contracts that lets value move without banks. Real-world uses include token crowdsales, ticketing, registries and IoT access control, but deployments face security problems at scale (including a roughly $150 million loss) and low throughput of only a few transactions per second. The talk highlights core technologies: public‑key cryptography, Merkle trees, and compact smart contracts (tens to a few hundred lines).
