Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
Gifto as a network protocol, is a brainchild of Andy Tian, the co-founder and CEO of Asia Innovations Group (AIG). The team at AIG comprises of crypto-technology and blockchain enthusiasts. Andy saw potential in designing a decentralized network powered by the Ethereum blockchain to fix the current broken content monetization model with a better model. Most people introduced to the global content industry will identify the following problems with the current model: The Gifto network was launched in December 2017 and has been tested along with AIG’s flagship product, Uplive. Uplive is a live streaming mobile application with over 20 million users. An official Gifto report in February 2018, stated that Gifto featured in the top 10 traded cryptocurrencies by volume. The universal blockchain-based virtual gifting protocol has not only bridged the gap between content creators and the audience but has also introduced a way to acknowledge and reward the content creators. Besides monetizing decentralized content, it has revamped the modern creator-audience relationship. It has already received support from a number of large institutional investors including KPCB and Wicklow Capital. This can only be seen a positive for Gifto as it proves that the idea has been scrutinized and accepted by a fairly large number of people.
