Ethereum summary

Introduction

Ethereum by Henning Diedrich. Blockchains offer revolutionary potential beyond digital currency, with Ethereum leading as a versatile programmable platform. The world entered the computer age in the 1980s. Personal computers became part of many homes and workplaces.

To some, this development was anything but welcome. It seemed to foreshadow a complete surveillance state. A handful of programmers decided to fight back. Their weapon was code.

Thus, in the late '80s, the cypherpunk movement began. Its main aim was privacy protection. Eric Hughes described its principles in his 1993 work, A Cypherpunk's Manifesto. The cypherpunks wanted safe, encrypted communication.

They also wanted people to conduct transactions without surrendering their privacy. Credit cards left records tied to conventional financial systems. The cypherpunks imagined digital money that could offer greater privacy. People could send and receive value electronically without depending on a central institution.

In some respects, it would resemble paying with cash.

the birth of digital currency

The Birth of Digital Currency. The cypherpunks experimented with technologies designed to make online communication and exchange more private. Anonymous remailers allowed messages to be forwarded without easily revealing their original sender.

Then came early proposals for decentralized digital money. One influential proposal was B-Money, created by Wei Dai. Remarkably, B-Money anticipated several ideas later associated with Bitcoin. Participants would maintain records of transactions, rather than relying entirely on one central authority.

Payments would be announced to the network. But the proposal never became a successful, decentralized currency. Other attempts at digital money followed. None achieved the breakthrough their creators hoped for.

Nearly a decade passed. Then, in 2008, Bitcoin became the first widely successful decentralized digital currency. Bitcoin's inventor is known as Satoshi Nakamoto. The identity behind that name remains a mystery.

But Nakamoto's intention was clear. Bitcoin would allow electronic payments without relying on a central financial institution. This is why Bitcoin does operate through one central registry. Transactions can be made directly between users.

A distributed network maintains the shared record. Bitcoin solved a problem that had frustrated earlier digital currencies. It created a practical way for strangers to agree on who owned what without trusting one central administrator. To understand why this mattered, we need to understand the blockchain.
