Yesterday released the «White book» for privacy Zk-starks. Positioned as a more secure version of Zk-snarks — technology privacy used by bitcoin zcash for — Zk-starks eliminates the need for a «trusted install». The publication of the white paper Zk-starks is likely to cause excitement in the developer community.
One of the authors of the document – Eli-Ben Sasson (Eli-Ben Sasson), Professor Israel Institute of technology Technion, who examined the proof with zero disclosure (ZK) for 15 years. ZK-proofs allow you to verify information without revealing anything about her. Zk-starks offer an alternative to the existing ZK cryptography, which has long been criticized for its potential disadvantages in the field of security and its size, which makes systems that use technology, slow and expensive.
In the «White book» stated:
«No ZK-system implemented in the code today (including used by these cryptocurrencies, as zcash for), yet are unable to simultaneously achieve both transparency and an exponential acceleration of verification for General purpose computing».
In addition, the paper details a proof-of-concept in which «the police proves that the DNA of the candidate is not contained in the database of criminals», without revealing any information about the database or DNA.
Their interest in Zk-starks showed a different team of cryptocurrency developers, including the Monero project that focuses on privacy. The Creator of Ethereum, Vitalik Buterin also studied this technology.
The developers of blockchain, it seems that this year we are going to focus on two key issues — privacy and zoom. Because privacy is actively developing, other ZK-system, such as Bulletproofs, focused on how to make them more lightweight. This will allow not to overload blackany who are committed to improving the scaling.
