The Cosmos network consists of many independent, parallel blockchains, called zones, each powered by classical Byzantine fault-tolerant (BFT) consensus protocols like Tendermint (already used by platforms like ErisDB). Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub. The architecture is a more general application of the Bitcoin sidechains concept, using classic BFT and Proof-of-Stake algorithms, instead of Proof-of-Work.Cosmos can interoperate with multiple other applications and cryptocurrencies, something other blockchains can’t do well. By creating a new zone, you can plug any blockchain system into the Cosmos hub and pass tokens back and forth between those zones, without the need for an intermediary. While the Cosmos Hub is a multi-asset distributed ledger, there is a special native token called the atom. Atoms have three use cases: as a spam-prevention mechanism, as staking tokens, and as a voting mechanism in governance. As a spam prevention mechanism, Atoms are used to pay fees. The fee may be proportional to the amount of computation required by the transaction, similar to Ethereum’s concept of “gas”. Fee distribution is done in-protocol and a protocol specification is described here. As staking tokens, Atoms can be “bonded” in order to earn block rewards. The economic security of the Cosmos Hub is a function of the amount of Atoms staked. The more Atoms that are collateralized, the more “skin” there is at stake and the higher the cost of attacking the network. Thus, the more Atoms there are bonded, the greater the economic security of the network. Atom holders may govern the Cosmos Hub by voting on proposals with their staked Atoms.
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).
