Paytomat is a blockchain-based payment processing system created to help merchants, consumers and crypto core teams to find each other and create real life traction for cryptocurrencies as emerging method of everyday payments. Built as a decentralized autonomous organization and decentralized franchise, Paytomat features two unique loyalty programs based on the PTM coin, incentivizing merchants to accept payments in crypto, and PTX token, incentivizing end customers to pay with crypto. For the purposes of the token sale we will use token called PTI based on EOS blockchain. Paytomat is a set of blockchain software solutions, already used by more than several hundreds Merchants to accept crypto in cafes, restaurants, beauty salons etc. Our product integrates into existing point-of-sale systems or offers a standalone solution without the need to purchase additional hardware. We hedge the risks, increase speed and streamline payments in multiple cryptocurrencies. For the Сustomer, it’s as easy as scanning a QR code with our own or any other compatible crypto wallet, and pay in one of the 15+ cryptocurrencies currently supported by Paytomat. For the Merchant, the enrollment is free and is done either via their POS (updating the software) or installing the Merchant App provided by Paytomat. The in-house developed proprietary system is now being migrated to EOS and includes “Paytomat Core” in the form of an EOS smart contract and services responsible for keeping Merchant accounts and balances, Merchant interfaces (Merchant Web Panel, Merchant App, POS integrations and e-commerce plugins) and consumer apps (non-custodial cryptocurrency wallets).
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.
