GSC (Global Social Chain) is the world's first new generation of social networking chain that owns hundreds of millions of social users. This social chain is determined to use block chain technology to subvert centralized social networks such as Facebook, WeChat, etc., which plays a dual role as 'manager' and 'arbiter' simultaneously for the former social networking platforms. Social network is the most important basic measure of the Internet. It conveys the user's daily high frequency interactive behavior. However, at present, all the centralized social networking platforms, such as Facebook, Snapchat, etc., are facing many pain points. The security of users' private information cant be guaranteed; The user data can be used by the platform at any time; There is a lack of incentive as the values created within the content of the user belong, at last, to the platform; Credit system vulnerability, false information, and low social efficiency. The social network is a natural source applied to the centralized block chain technology. GSC's vision is to utilize the block chain technology to restructure the values of the next generation of social networking platforms and let the security of the private data and the digital assets become individual. Through the in-depth cooperation with the famous social networking application Mico, we have the chance to validate the solution of the block chain technology on the product matrix of Mico and made very effective progress.
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.
