Zero is developing with snail speed.
Zero is the application currency of Zerocoin Zero Knowledge Proof. zero first appeared in 2014. After four years of development, Zero's market cap is $2,278,999 USD, supply is 99,992,520,283 ZER, ranking is only 765. Although it is considered to be very good in more than 1600 currencies, this development is comparable to snail speed.
Over the years, zerocoin's agreement has undergone new developments. At the beginning, problems of zerocoin have also been effectively solved, including Bit Commitment Technology.
The principle of this technology is to hide the original address and the number of coins, generate a string of code, you need to use some known data to decode the coin, others cannot get it. The erocoin includes a zero-knowledge proofing technique so that there is no direct relationship between the input bitcoin address and the output bitcoin address. However, it also has weaknesses, that is, the need for bitcoin block chain support. At the time, the Bitcoin development team refused to support it, so now it has turned to building its own chain.
In contrast, the development of melon is still very fast. It applies the blockchain technology asset management system. Not only can price inquiries and transactions, but also asset selection and risk management.
Modum is still very powerful. This year modum has cooperated with Swiss Post. This project has great prospects for the medical industry. The current market value of mod is $44,327,866 USD. The ranking is 246. I hope that the modum will be further improved in the future.
