Frequently Asked Questions

When was the Bitcoin whitepaper published?

The Bitcoin whitepaper, titled 'Bitcoin: A Peer-to-Peer Electronic Cash System,' was published by Satoshi Nakamoto on October 31, 2008. It introduced a decentralized electronic cash system using proof-of-work consensus, solving the double-spending problem without a trusted third party.

What was the DAO hack and why did it matter?

The DAO hack occurred in June 2016 when an attacker exploited a reentrancy vulnerability to drain approximately 3.6 million ETH (worth ~$60 million at the time). It led to the controversial Ethereum hard fork that split the network into Ethereum (ETH) and Ethereum Classic (ETC).

How do zero-knowledge proofs improve blockchain?

Zero-knowledge proofs allow one party to prove a statement is true without revealing the underlying data. In blockchain, ZKPs enable private transactions (Zcash), scalable rollups (zkSync, StarkNet), and identity verification without exposing personal information.

What technical problem did the Bitcoin whitepaper solve?

The Bitcoin whitepaper solved the double-spending problem in digital currency without requiring a trusted central authority. It achieved this through a combination of proof-of-work consensus, a distributed timestamp server, and economic incentives for honest network participation.

What is the significance of the Ethereum whitepaper?

Published by Vitalik Buterin in late 2013, the Ethereum whitepaper proposed a blockchain with a Turing-complete programming language, enabling smart contracts and decentralized applications. This expanded blockchain utility far beyond simple value transfer.
