REVIEW GOeureka

Platform Overview

GOeureka aims to develop an easy to use, reliable Facility and Services booking system with persistent indisputable records. As with all new systems, much of what is proposed will evolve over time as requirements change. The web platform will be developed with a backend built on the Python Django framework while individual components will be built using a mix of programming languages (HTML, CSS, Javascript, Golang, etc.) and the mobile application built on the Ionic framework. The database will be a PostgreSQL database that runs on a cloud server (Amazon Web Service) with certain data validated and stored on the Ethereum blockchain. Smart contracts will be ERC20 compliant (though newer standards may be applied after the time of writing) and customized using Solidity.

ERC20 smart contracts will be utilized for the security and immutability of data throughout the platform. To increase performance and keep transaction fees to a minimum, individual transactions and bookings will be kept outside of the blockchain. The settlement of all transactions will occur off-chain and fulfilled transactions will be aggregated each day and sent through the smart contract to be validated and stored on the blockchain.

It is a key goal that the GOeureka platform provides for widespread usage, therefore utmost priority will be given to platform performance, user interface and experience. Majority of the system will be built in off-chain components but critical information will be stored in persistent smart contracts. The critical factors addressed are:

● The design of a secure mobile wallet that the average user feels comfortable using and is recoverable by the same user in the event of a lost device.

● The GO token which can be held, spent or traded.

● The GO credits which offers preferential rates when purchasing products and services. An exchange allowing the purchase of GO credits in exchange for GO tokens

● A management system to allow booking and recording of scarce, non-fungible resources (e.g. room-nights). Making this booking comes from:

○ payment of deposit in GO credits (automatic)

○ acknowledgement by the payment facilities during deposit through classic methods

● A booking and payment system for less scarce resources - e.g. spa sessions, meals, activities etc.

What is the GOeureka?

GOeureka is a travel technology project that uses blockchain technology to build an online hotel reservation platform. GOeureka's mission is to decentralize the hotel reservation area and bring greater transparency by allowing hotels to connect directly with their customers. As a technology partner for hotels, GO aims to provide a dynamic digital experience for users and eliminate the high commission structure imposed by online travel agents. By reducing the hotel's financial commitment to third-party booking platforms, GO's vision is to allow the hotel to focus more resources on providing better value and better service to its guests. Travel around the globe.

Why Ethereum blockchain?

The blockchain provides GOeureka with the required token economics needed to eliminate high commission fees and the ability to facilitate interoperable loyalty points. GOeureka’s platform also benefits from the distributed ledger technology that guarantees security and transparency across its platform.

GOeureka chose the Ethereum blockchain due to its flexible and extensible nature. The use of Ethereum smart contracts allows for the creation of “autonomous agents” that may be implemented throughout GOeureka’s platform to automate many processes and remove various third-parties that usually result in a slower process and multiple transaction fees that lead to high costs.

While moving towards a fully decentralized platform, GOeureka will look into the adoption of key blockchain technologies such as zero knowledge proofs, off-chain computation solutions and recently introduced Ethereum technology like the Plasma and Raiden network.

The Proxy Wallet

One key issue typically faced when designing a blockchain system for mass adoption is the handling of user wallets. While a hardware wallet like a Ledger Nano or a plug in like Metamask can expect users to use a recovery phrase, general users are unlikely to be happy with such a solution. We intend to use what is called a proxy wallet for all Ether transactions:

1. Users will undergo a proof of identity when signing up for GOeureka

2. Cryptographic Key Pairs are created on user devices and never leave their devices

3. A corresponding smart contract called a “proxy wallet” will be created on the blockchain

4. The user channels all transactions via the proxy wallet which is tied to the user’s identity

5. The proxy wallet allows the user to interact with all parts of the GOeureka system

6. On registration of a lost phone, GOeureka can, via a rigorous process, establish the identity of the account and assign that person’s new address to be the new controller of the proxy wallet.

The proxy wallet is already in use in several organisations.

Payment Processing

GOeureka aims to provide multiple payment methods that appeal to both traditional and crypto consumers. Consumers will have the option to transact using fiat currency, major cryptocurrencies, GO credits or loyalty points. Prices of goods and services will be displayed in fiat and the cryptocurrency of user’s choice. There are multiple available approaches for the development of GOeureka’s payment processing.

For the traditional checkout process where payment is made in fiat, GOeureka will implement a third-party payment gateway. This method sees payment being processed through a payment gateway (e.g. PayPal) that sends transaction details to a payment processing network (typically hosted by a merchant’s bank). Once processed, the processing network sends approved data to the credit card issuer to proceed with the funds transfer.
