Monero<\/h2>\n\n\n
The Monero project was launched in 2014. Technologies that provide privacy in Monero: ring signatures, ring confidential transactions, and stealth addresses. Recently Dandelion++\u00a0has also been implemented<\/a>. These technologies mix the spent coins in a network of false paths (decoys), hide the sent amounts and recipient addresses.\u00a0<\/p>\n\n\n\n The key terms in the above paragraph are \u201cmix\u201d and \u201chide\u201d. When something is mixed, it becomes difficult to track it down because there is too much noise \u2014 it\u2019s like listening to one song while 10 others are playing at the same time. In this analogy, the number of songs is called the \u201canonymity set\u201d. This provides good, but not perfect, privacy. Monero was one of the first anonymous cryptocurrencies to deal with user privacy vulnerabilities in the past (see the Monero Research Lab\u00a0page<\/a>\u00a0for its remedial measures).<\/p>\n\n\n\n zk-SNARKs technology provides a high level of anonymity in any cryptocurrency. This technology is independent of mixing. By analyzing the blockchain, you will not find any information about the senders, recipients, or transaction amounts. Validation in the system is provided without providing the observer with any useful information. <\/p>\n\n\n\n However, Zcash has had to pay for this seemingly magical privacy technology. The compromise was\u00a0trusted setup<\/a>. This is a critical phase of the network launch when random data is generated by a group of people who should not share this data with each other. When this data is combined, it can be used to create fake Zcash.\u00a0<\/p>\n\n\n\n Just because the privacy of a coin is independent of mixing does not mean that the set of anonymity is endless. Anonymity on the blockchain is made possible by the fact that all network users use it. In Zcash, unfortunately, this is not entirely true, because in the Zcash blockchain there are two types of addresses \u2013 t-addresses and z-addresses \u2013 and only transactions between z-addresses are completely anonymous. T-addresses are as transparent as regular Bitcoin transactions.<\/p>\n\n\n\n And the thing is, most of the transactions are transparent. It says nothing about the Zcash itself, but about people\u2019s habit of sacrificing anonymity to usability.<\/p>\n\n\n\nZcash<\/h2>\n\n\n
