back to the coin circle, of course, anonymous mining coins are the most talked about recently. Whether it is to return to the essence or to pay tribute to BTC, the essential core is that anonymous coins have undoubtedly become a kind of complete industrial chain in the current blockchain project under the premise that the bottleneck of technology restricts the practicality of blockchain technology: from B-end technology development and community development to C-end users.

recently, ZCASH large coins were exposed to a serious metadata leak, allowing the sender to obtain the IP address of the receiver, and almost all zcash forked coins were affected. As we all know, after zk-SNARKs zero-knowledge proof was first realized, it was called anonymous three musketeers with Monroe and Da Shi. With a market value of 3 million dollars, it plays an extremely important role in the development of anonymous technology. However, Zcash seems to have been living under the aura of Dash and Monero, and the number of active addresses in the chain, transaction volume and other indicators are behind people. With Grin & The rising star MW technology represented by Beam also launched an impact; Ethereum, the second largest public chain, has repeatedly demonstrated its ambition to adopt zk-SNARKs technology.

Of course, what worries us most about Zcash is the 2% pumping problem. The embarrassing thing is that the development company has already spent more than it can make ends meet. It is foreseeable that there will be a crisis of survival after halving the mining tax next year. There are talented people in Jiangshan generation, each leading the way for hundreds of years, and the stage of technical competition never rests. Perhaps Zcash does not act and loses the mining tax on all sides, but its main similar functions are forked coins that want to take advantage of the situation!

First, David Byrd, the representative of Ernst & Young, exposed the shortcomings of Zcash, bluntly saying that it has the problem of low utilization rate of privacy transactions, and the cost of privacy transactions with Zcash is quite expensive, which also makes most transactions on Zcash not use zk-SNARKs technology.

Tim Davis, the head of Deloitte's "chain reform" business, directly said that "Zcash is a failed project" and "it will only go so far".

Electric Coin Company, the development company of zcash project, disclosed its transparency report for the second half of 218, in which the financial deficit of $3 million benefited from the positive progress brought by unfair pumping of up to 2%. Can it be maintained? We are not optimistic.

zk-SNARKs zero-knowledge proof originated in 199, and related concepts were put forward by cryptographer Jean-Jacques Quisquater (and other collaborators) in the paper How to Explain Zero-knowledge Proof Protocol to Children. ?

? The full name is zero-knowledge successful non-interactive arguments of knowledge.

simplicity:? Compared with the actual calculated length, the generated zero-knowledge evidence message is very small. ?

Non-interactive:? There is almost no interaction, which means that anyone can verify zero-knowledge evidence without any interaction.

Arguments:? Verifier can only resist the attacks of provers with limited computing power. Provers with sufficient computing power can create forged zero-knowledge evidence to deceive the verifier (note that enough computing power just mentioned can break public key encryption, so don't worry at this stage). ?

of Knowledge :? It is impossible for a prover to construct an effective zero-knowledge evidence without knowing the specific witness. ?

Zero is a branch of ZEC coin. Since its launch in February 217, it has adopted its own independent algorithm, combined with the hybrid proof mechanism of pow and pos, and the anonymous core uses zk-SNARKs zero-knowledge proof technology.

Zer has a total volume of 17 million, a circulation of 7 million and a market value of 8, USD. There is no love for western Europe, no pre-excavation, pure community drive, and completely abandon the unfair problem of 2% pumping with large change ZEC. Using equihash 192/7 algorithm, compared with zec's equihash algorithm, zer's algorithm has more complicated parameter time, higher memory requirements, more power saving and environmental protection. The block time is 2 minutes. The block rewards 2% service nodes, 72.5% mining and 7.5% governance.

At present, mining can be done anonymously, and the exchange can be connected anonymously with a unique auditing system. It is worth noting that anonymous sending on the mobile phone has been basically developed successfully and will be launched soon. Committed to creating an anonymous coin with full anonymity from beginning to end, cross-platform, instant arrival and zero transfer fee.

at present, the four community developers are not well-known gods, but in cooperation with zel, the founders of zel team, Miles Manley and Daniel Keller, are also buying zer and running the node. It is the biggest recognition to be able to get the buy from the same dev peers. At the same time, the zer team has also overcome the problem that the zero-currency system has been unable to achieve anonymous sending of mobile phones, and will release a brand-new mobile wallet in the near future.

in the early days, the main battlefield was cryptopia, New Zealand. With the collapse of cryptopia, most active people, including many coins pushing extra-large V, were on it, resulting in those big V's rarely mentioning Zers. This is the biggest constraint on Zers and correspondingly reduces the circulation of ZERO, and regularly releases 7776 Zero (currently about 3,8 RMB) every day.

At present, there are 1,5 people on discord, 1,2 people on telegraph, 5 people on Turkish community telegraph and nearly 2,7 people on Twitter. Due to the ownership of activists' money, the community activity is low now. But among the 2,7 people on Twitter, there are many big V's, which can be said to be an undercurrent.

zec's development fund expires next year, and zec is facing great changes. does zec have the motivation to continue to maintain the project? Or let it go and return it to the community? This is the biggest huge thunder, or provides an opportunity for zer.
