Project goals

This project aims to promote decentralized economy and technology by offering a mobile app platform that can be easily used by any business, startup or community. Project authors build upon their expertise in the domains of mobile app development (iOS and Android), real-time communication (Erlang, ejabberd, XMPP) and blockchain (Ethereum) deeply believing the combination of these technologies offers the key missing gateway for average users into the decentralized economies of the future.

Using Ethora codebase you can easily create and publish your own iOS and Android app for your community, equip your members with crypto wallets and get a crowd-sourced community building going supported by your own ERC-20 and NFT token economy. Real-time communication features (chat rooms, messaging, push notifications) help to keep your community sticky, engaged and viral. You can track your community metrics (user registrations, app usage, token transfers, messages) using Google Firebase or built in analytics provided by Dappros Platform.

Disclaimer

Our platform provides technology for ecosystems built on the principles of openness, transparency and decentralization. By design, certain information such as user profiles, rankings, and the transactions of digital assets will be available to the whole ecosystem or to the public. You should not use the standard version of this product for storing or sending secure or commercially sensitive content. You should not use any versions of this product for emergency communications. You should not share information or content through our platform in cases where you may not be comfortable or authorized to share it with the public.

Note: enterprise-level version of Ethora engine (additional security layers, custom user sign-on mechanisms, Professional Services & SLA package) is available under a separate license from Dappros.

Developers and Funders

Ethora mobile app codebase, Dappros Platform backend (Ethereum-based infrastructure, core application, wallets handling, caching, Web3 and API layer) are developed and supported by Dappros. Real-time communication infrastructure (Ejabberd chat server and custom application logic, Push Notifications, statistics and monitoring) are developed by DeepX.

The project is currently (2018-2021) developed and funded solely by these two privately owned companies, however our aim is to transition project governance to an open-source foundation / DAO as soon as practical, provided the activity from the open-source community becomes significant to justify such transition. In such case the existing entities will focus on commercial services and enterprise version of the engine, while the project core development will be governed by a foundation / DAO under the principles of open source software.

Commercial & licensing model

Our approach to licensing is similar to a 'Red Hat model' where we offer most of the product open-source so that a wide global community can benefit from it and contribute to its further development, but we also offer commercial licensing and technical support options for businesses and enterprises to help fund further development of the product.

In terms of license and code availability the product can be broken down as follows:

• Client-side (mobile app): (A): free, open-source under GPL license; (B) Paid-for commercial license with security add-on and SLA package.
• Server-side: freemium (free cloud plan fits most startups and non-commercial organizations, paid SLA and dedicated hosting plans available for businesses that require them).

Future plans & roadmap

DAO governance vision

Currently (2021) Dappros is a privately owned company that offers an open-source mobile app, open-source private blockchain and closed-source backend. Our founders promote decentralized economy and free p2p communication technologies for many years. We are developing a roadmap where the platform will become fully open and its governance can be transferred to a decentralized organization. In such scenario, we will remain a private organisation offering implementation and SLA services, but the development of the new versions of the platform engine and maintenance of the publicly available infrastructure will become globally distributed and decentralized. Our only limiting factor here is funding and time constraints.

Roadmap 2018-2021

• A platform allowing businesses and creators to easily set up and for users to join and explore a tokenized p2p ecosystem
• Partially centralized
• Assets and transactions ledger are decentralized
• Leveraging state of the art DLT, mobile and communication technologies
• Mobile-first ("no ads, no gimmicks")
• Open-source client

Roadmap 2022-2023

• Self-Sovereign Identity - users own their identity, content and assets
• Open-source server - anybody can download and run a Validator or Host node (closed-source enterprise version possible for private chain projects)
• Validator / Hoster incentives - self-supporting network
• Easy sidechain / mainchain assets transfer

Roadmap 2024-2025

• Decentralized maintenance allowing both (a) incentivized hosting of the public infrastructure and (b) private networks. À la Ethereum;
• R&D grants available for teams and individual developers contributors globally
• Decentralized governance - platform stakeholders make important decisions for the public network
• Meritocracy - governance stakes are earned through supporting platform infrastructure (running nodes), R&D work and platform promotion
