Privacy-preserving computation on blockchains could prevent breaches
Business is a resource game, and blockchain offers a means to win it, enabling interoperability with privacy-preserving computation. In the 19th century, the barons of American industries rose to prominence by leveraging their hold on tangible resources like oil and steel. Today, corporate titans seek to attain even greater heights of wealth by gathering consumer data. But now, like then, the benefits of accumulating such resources come paired with a significant business risk: spillage.Like oil spills, data leaks — regardless of whether they occur accidentally or as a result of hacker....

Mass adoption of privacy-preserving computation might become a significant improvement for blockchain. Is anyone doing it yet?ArpaChain, a secure computation network compatible with blockchain, uses an MPC protocol that creates ways for multiple entities to collaboratively analyze data and extract data synergies while keeping each party’s data input private and secure.Earlier this year, Arpa joined the commission on Blockchain technologies and the crypto economy of Russia. The development team also engaged in a large-scale test for preserving privacy. ARPA’s team is currently focused on....
Zcash, which is an implementation of the zerocash concept, is often referred to as the first form of truly anonymous digital cash. While Bitcoin been called a haven for criminals by many misinformed individuals, the reality is Satoshi Nakamoto’s creation is a mostly-transparent ledger. Although Zcash enables the highest level of privacy currently allowed by cryptography, there are still some potential issues (mostly unrelated to privacy) for the financial-anonymity protocol to overcome. Zcash CEO Zooko Wilcox-O’Hearn recently discussed some of these issues on Epicenter Bitcoin. Privacy....

One of blockchain’s greatest challenges that’s yet to be solved is the lack of confidentiality and privacy of data. It’s a challenge that needs to be addressed though, because until a solution is found then blockchain will always be out of the question for enterprises that put a premium on data privacy above all of […]
