1.4. Overall Description

“ExzoCoin” project includes two main components:
1.4.1. A web-based application that will provide a platform for decentralized cross-chain conversion of digital assets based on 1INCH API. This application will have the similar design and functionality as the 1INCH app (https://app.1inch.io/). The process of interacting with the application could be described in the following simplified steps:
1.4.1.1. Navigate to the swap application from ExzoCoin website
1.4.1.2. Connect wallet with Metamask or WalletConnect
1.4.1.3. Buy cryptocurrency via MoonPay
1.4.1.4. Use bridges to move coins cross-chain
1.4.1.5. Select the chain
1.4.1.6. Set the direction of exchange
1.4.1.7. View the details of the deal (rate, fees)
1.4.1.8. Set additional parameters (gas limit, slippage)
1.4.1.9. Confirm the deal
1.4.2. A blockchain network based on Fantom blockchain fork that will provide an ecosystem for creating customized blockchains, deploying smart contracts, with full support of Solidity smart contracts. This solution will allow users to perform the following use cases:
1.4.2.1. Use Exzo Network official wallet
1.4.2.2. Use Exzo Network native coin ExzoCoin
1.4.2.3. Connect with Metamask to the testnet and mainnet
1.4.2.4. Run a validator node
1.4.2.5. Run a read-only node
1.4.2.6. Stake native ExzoCoin and get a reward
1.4.2.7. Deploy a smart contract written in Solidity
1.4.2.8. Create a fixed-cap asset
1.4.2.9. Create a variable-cap asset
1.4.2.10. Create a local test network
1.4.2.11. Explore the network for transactions and other on-chain data

1.5. ExzoSwap High-Level Solution Architecture

Fig.1. ExzoSwap High-Level Architecture
1.5.1. ExzoSwap FE App is a standalone React application. This application is built into several js and CSS files and is meant to be served from the s3 bucket using cloud front.
1.5.2. ExzoSwap App is integrated with 1INCH API through a secured VPN connection.
1.5.3. A user interacts with ExzoSwap App from their web browser using Metamask extension (or Wallet Connect integration) for making transactions.

1.6. Exzo Network High-Level Solution Architecture

Fig.2. Exzo Network High-Level Architecture
1.6.1. A Validator node consists of three components: state machine, consensus and networking.
1.6.2. An application can communicate to a node via CLI. Opera network supports auditing by permitting participants to join in post-validation mode.
1.6.3. An observer (or Monitor) node consists of a state machine, post validation component and networking component.
1.6.4. The network supports three types of participants: users, validators and monitors.
1.6.5. Each validating node can create new event blocks. Generation of a new event block indicates that the new block and all of its ancestors have been validated by the creator node of that new event block.
1.6.6. The consensus mechanism is inherited from the Fantom’s Opera Network and described in the Lachesis Whitepaper (https://arxiv.org/pdf/2108.01900.pdf)
