On January 10, Barry Silbert, founder of Grayscale Fund and founder of DCG
Publicly announced that Grayscale Fund will add two new tokens to its cryptocurrency portfolio: ZEC and ZEN. And tweeted: 2021 should be the year of privacy protection, decentralization, and resistance to censorship.
On January 12, after 20 days of suspension, Grayscale Fund reopened the subscription of cryptocurrency funds and accepted new investment. In this new cryptocurrency portfolio, Grayscale suspended the subscription of ETH and XRP, while the previously mentioned ZEN and ZEC are included in the subscription. At present, Grayscale has disclosed new purchase data, among which, the minimum limit of BTC is 50,000 US dollars, and the minimum limit of BCH, ETC, LTC, ZEN, ZEC, and XLM is 25,000 US dollars.
Affected by this, both ZEN and ZEC rose sharply after the market opened on January 12. As Barry Silbert, the founder of Grayscale Fund and the founder of DCG, said, with the rapid development of the times, when issues such as information out of control, personal privacy leakage, and unrestrained commercialization have become the sharp pain points of personal privacy protection in the current era, people are concerned about personal privacy. Privacy and information security are becoming more and more important.
Perhaps there has never been a technology that takes your privacy as seriously as blockchain. As the currency that mainly protects privacy, the anonymous currency has returned to the popular line of sight.

The Old Glory of Privacy Coins — Monero (XMR)
Monero (XMR) is an open source cryptocurrency created in April 2014. XMR is committed to becoming a replaceable and untraceable electronic currency. Compared with Bitcoin, XMR is based on the CryptoNote protocol, and has significant algorithm differences in blockchain obfuscation, and has a higher degree of anonymity than Bitcoin. Compared with other anonymous coins, Monero can not only hide the transaction parties and transaction amount, but even the transaction IP can be hidden.
Due to its strong anonymity, untraceability, extremely low transaction costs, and relatively complete ecological construction, Monero has quickly won the favor of anonymous currency enthusiasts all over the world, including dark web transactions, which is also why it has been attacked by governments of various countries in the future. The investigation laid the groundwork.
In 2018, Monero upgraded the significant bulletproof protocol (Bulletproofs). The transaction size is 2.5 KB, which is about 80% smaller than before. The transaction verification speed of the block is accelerated by 40 times, and the verification speed of a single transaction is accelerated by 5 times. times, which is of great significance to the development of Monero. The currency price was also affected by this, rising all the way to around $400.
However, Monero is not so perfect. One is that XMR has been criticized for being resistant to ASICs. Although Monero has tried its best to resist ASICs to avoid centralization, Monero is close to 40% of the computing power. The power is still owned by three mining pools. Second, although Monero achieves a high degree of privacy, the price of privacy is a lot of extra computing and resources. The single transaction size of Monero is 2.5KB, which is higher than that of Bitcoin. Ten times the size of a single transaction.
XMR current price: $165,

Similar to Zcash but better than Zcash — Zcash XZC (now renamed FIRO)
When it comes to Zcash, people usually think of it as an altcoin of Zcash. Although the theoretical papers of Zcash and Zcash are written by the same author, and both use zero-knowledge proofs, there is no difference between the two projects. They are completely different encryption technologies, and both have different performances in encryption algorithms, confidentiality, and traceable supply, and each has its own advantages.
Zcash (XZC) is a cryptocurrency that uses the zerocoin protocol to protect account privacy. It is the first cryptocurrency to implement the Zerocoin protocol, which uses zero-knowledge proofs to ensure that the relevant address information of both parties to the transaction is not leaked. At present, as a payment token with the main anonymous function, there is still a gap in the market value of Zcoin compared with Dash, Monero and other leading projects in the market. However, Zcoin uses the current relatively advanced anonymous technology and realized it in Thailand To a certain extent, Zerocoin has achieved a large-scale practical application in the general election in Thailand and the application of payment scenarios for 5 million Thai merchants. From a long-term perspective, Zerocoin still has development prospects.
In terms of currency price performance, Zcash also has a glorious history, with the highest price briefly stabilizing at around $100.
Zcoin current price: $4.11.

18,000 times miracle anonymous coin in 9 months—XVG
Verge (XVG) was released on October 9, 2014, referred to as XVG in English. It is an open source cryptocurrency (100% POW) based on Bitcoin technology. The core algorithms are Scrypt and x17. The block time is only 30 seconds and rewards are recalculated based on the total number of blocks generated. It supports scrypt, X17, lyra2rev2, MYR groestl, blake2s multi-algorithm mining, so people with different types of mining machines can mine this currency. The design of Verge coin is to facilitate the payment amount in daily use. When it was first born, the name of XVG was still DogeCoin Dark (DogeCoin Dark). It was not officially changed to XVG until 2016.
In terms of technical characteristics, XVG may not have much innovation, but the most talked about is the myth of XVG’s 18,000 times wealth in 9 months. Before April 2017, the price of XVG with a total amount of 16.5 billion has been 0.00001-0.00003 The U.S. dollar fluctuates within a narrow range, and the daily trading volume is only a few hundred thousand dollars. Since mid-April, the daily trading volume of XVG has continued to increase, and the price has easily increased by 10 times from around 0.000016. After a month of rest, XVG started again, and the price reached $0.006 in early June. In less than two months, XVG rose 300 times. Since then, the price of XVG has not moved much. However, at the end of November, XVG suddenly did not start to rise from 0.005. Finally, on December 24, 2017, the price successfully stood at $0.287, with a daily trading volume of $1.1 billion. So far, XVG has successfully increased by 18,000 times in 9 months.

Gemini of Anonymous Coins in the New Era—GRIN and BEAM
In July 2016, on the Bitcoin Research Channel, an anonymous developer named Tom Elvis Jedusor (the name of Voldemort in the French version of the Harry Potter series) released a white paper called Mimblewimble. Scalable, privacy-based blockchain protocol. It can verify all valid transactions without storing the entire history of the chain.
Grin is the first design application to implement MimbleWimble. Started research and development in 2016 and launched the main network on January 15, 2019. Inspired by Grin, the Beam team started research and development in April 2018, becoming MimbleWimbles second design application. Although they are both based on MimbleWimble, the development concepts of Beam and Grin are not the same, which also causes the believers of the two coins to fight with each other from time to time. Grin is mainly implemented by the Rust language, while BEAM is implemented by the C++ language; Beam uses the Equihash algorithm, while Grin uses the Cuckoo Cycle algorithm; Grin is based on the community, while Beam is operated by a company group; Beams main economic source is Its own tokens, while Grin relies on community donations; the total amount of GRIN is unlimited, and the total amount of BEAM is 263 million.
As the twin stars of anonymous coins in the new era, GRIN and BEAM also attracted market attention in terms of currency price trends at the beginning of their launch.
On January 8, exchanges such as Hotbit, MXC, and QBTC actively launched Beam, which skyrocketed by 500% at the opening, reaching a peak of 55 yuan, and then the price quickly fell back to around 10 yuan in the off-exchange market. On January 16th, GRIN ushered in the upsurge of listing on exchanges. Many exchanges listed GRIN, and the currency price reached as high as 96 yuan.
Current price: GRIN 2.4 yuan BEAM 2.2 yuan
Listed exchanges: Currently GRIN is not listed on the top exchanges, and they are all on second-tier exchanges such as MXC and hotbit, while BEAM is on the top exchange Binance.
Since ancient times, human beings have used encryption technology to ensure the security of some important information. Today, with highly developed information, people pay more attention to the protection of personal privacy. Therefore, an important significance of blockchain anonymity protection is to reduce real-world privacy threats.
