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.
TrueUSD provides its token holders regular attestations of escrowed balances, full collateral, and also the legal protection against misappropriating underlying USD. The team believes that TrueUSD will be able to come up with the stable trading instrument for the traders of cryptocurrency that has been long-awaited. This will allow the businesses and consumers to use the digital currency as a medium of an exchange. The goal of the TrueUSD team was to build a coin that is stable and which can be used and trusted by them too. TrustToken is a platform that creates the tokens backed by assets that can easily be purchased and sold all around the world. The first asset token of TrustToken is TrueUSD, which is a stable coin and can be redeemed 1-for-1 for US dollars. TrustToken have partnered with registered fiduciaries and banks for holding the funds securely backed by TrueUSD tokens. To increase the amount of security, fiduciaries, and banks directly handle all the funds. Escrowed funds do not give access to the TrueUSD system. TrueUSD works with various trust companies which already manage around billions of dollars. Just pass an AML/KYC check, send USD to a trust company with an agreement of escrow. When the funds get verified, their API tells the smart contract of TUSD to mint an equal amount of TUSD to your public Ethereum address. The USD funds are regularly verified in scheduled attestations by a very much trusted auditing firm. USD funds are kept safely in a third party account, that is escrow accounts, wherein TrustToken does not hold any direct access to the funds and cannot abscond with them even if they wish to. The token burning and minting system makes sure that every TUSD token is backed by 1 USD. A mandatory check of AML/KYC makes sure that TUSD keeps shady people away from the entire project. TUSD makes faster transactions in low transaction fees. Even though TUSD is a unique offering, it is most likely overshadowed by its bigger competitors - Tether. While TUSD arguably offers more security and features, it may be losing the marketing battle. This is not to say that the situation will remain the same. With more crypto investors joining the market every day, the good times for TUSD may be on their way.
