Main anonymous goods _:
1, dash, coin mixing technology. DASH, formerly known as black coin, is a technical improvement based on bitcoin, with good anonymity and decentralization. It is the first kind of digital currency with the purpose of protecting privacy, and you can feel that it is loved by the black market by listening to its name. DASH 2065 438+04 released a white paper with a total circulation of18.9 million. The main features of currency are as follows: 1. Double-layer reward network, or master node network technology;
2. Real-time payment function, timely collection and low handling fee. After DASH came out, it was regarded by netizens as the currency that can best realize Satoshi Nakamoto's dream.
2. Monroe coin (XMR) and _ ring signature technology. Monroe Coin is an open source cryptocurrency, which was founded in April 20 14, focusing on privacy, decentralization and expansibility. Different from many cryptocurrencies derived from bitcoin, Monero is based on CryptoNote protocol, and there are significant algorithm differences in blockchain fuzzification. Monero's modular code structure has been appreciated by Wladimir J. van der Laan, one of the core maintainers of Bitcoin. The issuance of Monroe coins provides users with stronger privacy, and prevents double flower attacks by using stealth addresses to hide transaction data and key portraits. Monroe coin uses ring signature in mixed protocol, and every transaction in Monroe coin uses ring signature scheme to generate a key portrait, which is the result of performing one-way function on the private key of a given user. The information contained in the portrait can let the third party know that the transaction has been correctly formed and there is no attempt of double flower attack. In Monroe coin, ring signature is combined with hidden address, which is a one-time address and is not related to any user. The recipients of money can confirm their storage location by using the private "view key", and then use the private "consumption key" to form a ring signature to spend the money.
3.ZEC adopts zero knowledge proof technology. ZEC is a branch of code modification based on Bitcoin version 0. 1 1.2, which retains the original mode of Bitcoin and was released on 20 161October 28th. The difference between ZEC and BTC is that it automatically hides the transaction information (sender, receiver and transaction amount), and only those who have the private key have the right to view the transaction information. ZEC is a privacy technology based on blockchain. Unlike Bitcoin, ZEC transactions automatically hide the sender, receiver and amount of all transactions in the blockchain. Only the person who holds the viewing key can view the transaction content. The user has complete control, and the user can selectively provide the viewing key to others.
