Client’s team wanted to create a comprehensive platform for launching ICO campaigns to minimize the amount of efforts for each individual ICO campaign. Introducing a solution, our client wanted to make a platform for projects to conduct funding and skill-sourcing activities. • • • Develop a tool that will be issuing ERC20 tokens Integrate freelancer marketplace into the system Implement built-in ERC20 token exchange system The platform’s ultimate goal is to facilitate a more efficient allocation of capital and human resources among projects within the blockchain space. Thanks to a decentralized infrastructure, participation and contributions could be made with minimal bureaucratization. CROWDFUNDING PLATFORM FOR ICO TECHNOLOGIES: • • • Ethereum: Solidity, Truffle, OpenZeppelin Frontend: HTML5/CSS, AngularJS, SASS Backend: Java 8, JOOQ, HikariCP, Spring boot, web3j RESULT: Develop Solidity smart contracts for every subactivity according to client’s requirements Create templates for typical ICO and hiring terms for usage on both platforms (backers/freelancers) Make user-friendly and easy-tounderstand web-interface that links all components together and allows users to easily navigate through the platform CONSTRUCTION MONITORING TOOL CHALLENGE: SOLUTION: Real estate development company needed to develop a solution that will help to overcome main industry challenges: construction progress monitoring, construction process facilitation, proper resources allocation. We’ve developed a comprehensive blockchain-based solution for speeding up construction audit process by automating milestone planning. The system has to resolve common issues that are faced by both developers and constructors: mutual trust, compliance with the contract's terms and conditions, fast critical situation handling, financial transaction issues. • • • • Smart contracts integration Custom RFID tags id generation Blockchain-based financial transaction processing Real-time construction process monitoring CONSTRUCTION MONITORING TOOL TECHNOLOGIES: • • • • Backend: Java 8, Spring boot, RabbitMQ Blockchain: Hyperledger Fabric, Smart Contracts based on golang Android: Java, Volley, Gson, Paho MQTT, FCM, Instabug, TestFairy iOS: Swift 3, CoreData, Alamofire, Auto Layout RESULT: We’ve delivered an MVP product that includes: • • • Fundraising marketplace Smart contract hub for construction API integration for the platform We continue working on the platform creating a solution that would link together IoT, BI analytics, and blockchain. ICO FOR REAL ESTATE DEVELOPMENT PLATFORM CHALLENGE: SOLUTION: Real estate development company wanted to launch an ICO campaign to pitch their new project. We were asked to handle technical part of the campaign and ensure smooth user experience during ICO. As to accomplish a set goal, our team needed to: • • • • • Define blockchain purpose in the system Pick the technology stack and develop token economy Prepare platform description Prepare specification for smart contracts terms description. Perform all ICO-related development activities CONSTRUCTION MONITORING TOOL TECHNOLOGIES: • • • • Bitcoin: BIP32 Deterministic Wallet Ethereum: Solidity, Truffle, OpenZeppelin, Parity Backend: Java 8, JOOQ, HikariCP, Spring boot, BitcoinJ, web3j Infrastructure: AWS Auto Scaling group RESULT: One of the main difficulties of the project was constant changes in smart contracts specification and tight timeline. At the end of the project we’ve managed to deliver: • • • • • ICO smart contracts (Token, Multisig Wallet, etc.) Payment Gateway. Process bitcoin orders via REST API Ethereum Oracle. Checking status of bitcoin payment and sending ERC20 tokens. Smart contracts demo in the Ethereum test net.
