Ethereum
The decentralized platform for digital ownership and global transactions
About Ethereum
Ethereum is a decentralized, open-source blockchain platform that enables users to control their assets, data, and identity. With a proven track record of 100% uptime since 2015, Ethereum offers direct ownership, public rules, and global accessibility without permission or credit checks. It is maintained by a worldwide community of independent operators, ensuring no single entity can control or shut it down.
FAQ
A zero-knowledge proof is a method where one party (the prover) can prove to another party (the verifier) that a statement is true without revealing any additional information apart from the fact that the statement is true.
Zero-knowledge proofs eliminate the need to reveal sensitive information to prove the validity of a claim. For example, you can prove your citizenship without sharing your passport details, reducing the risk of data breaches and identity theft.
Zero-knowledge proofs are used in anonymous payments (e.g., Tornado Cash), identity protection (e.g., Bhutan’s National Digital ID), authentication, and verifiable computation for blockchain scaling (e.g., zero-knowledge rollups).
World ID uses zero-knowledge proofs to allow users to prove they are unique humans without revealing personal information. It relies on the Semaphore protocol to generate proofs that confirm membership in a verified group (e.g., humans) without disclosing specific details.
Yes, zero-knowledge proofs are used in offchain scaling solutions like zero-knowledge rollups and validiums. These protocols execute transactions offchain and submit proofs for verification on Ethereum, reducing network congestion and improving transaction speeds.
Zero-knowledge proofs can be used in solutions like MACI (Minimum Anti-Collusion Infrastructure) to hide how users vote, preventing bribers from inspecting onchain activity to influence votes. This helps maintain the integrity of voting-based mechanisms like quadratic funding.
