Abstract
|
Blockchain technologies rely on a public ledger, where typically all transactions are pseudoanonymous and fully traceable. This poses a major flaw in its large scale adoption of cryptocurrencies, the primary application of blockchain technologies, as most individuals do not want to disclose their finances to the public. Motivated by the explosive growth in private-Blockchain research, this Statement-of-Knowledge (SOK) explores the ways to obtain privacy in this public ledger ecosystem. The authors first look at the underlying technology underling all zero-knowledge applications on the blockchain: zk-SNARKs (zero-knowledge Succinct Non-interactive ARguments of Knowledge). We then explore the two largest privacy coins as of today, ZCash and Monero, as well as TornadoCash, a popular Ethereum Tumbler solution. Finally, we look at the opposing incentives behind privacy solutions and de-anonymization techniques, and the future of privacy on the blockchain.
