in xlc •  2 years ago  (edited)


We are a new gaming company, our core business is making new great browser and mobile games.

We concentrate on the development of free-to-play games that yield profits through the in-game micropayments.
Our objective is to focus on delivering successful and easy-to-use games.

Along with Game development, we take up on electronic micropayments, this is why we are launching LeviarCoin, a ready-to-use fraud prevention over Blockchain software.

In few words

LeviarCoin, by its nature, is not only a software protection tool, but also a currency.


  • Create a currency that can be easily traded or used as in-app/software currency.
  • Build a protection library to inhibit frauds in online applications and games.
  • Embrace open-source philosophy by releasing all source code of software, libraries and contributing with patches.

CryptoNote based

LeviarCoin is a CryptoNote-based currency, which implements its known main features:

  • Untraceable payments
    It provides users with a completely anonymous payment scheme and implements the ring signature technology which allows you to sign a message on behalf of a group. Learn more...
  • Unlinkable transactions
    By using a variation of the Diffie-Hellman exchange protocol, a receiver has multiple unique one-time addresses derived from his single public key. After funds are sent to these addresses they can only be redeemed by the receiver; and it would be impossible to cross-link these payments. Learn more...
  • Double-spending proof
    Nobody is able to spend the same money twice — even if all his signatures are anonymous. Every signature contains a key image. These key images are used to prevent double-spending. Learn more...
  • Blockchain analysis resistance
    Non-repeating one-time addresses and mixed keys in ring signatures make the whole blockchain resistant to analysis. Learn more...
  • Egalitarian Proof of Work
    The proof of work mechanism acts as a voting system. CryptoNote brings this equality with its egalitarian proof of work, utilizing built-in CPU instructions, which are very hard and too expensive to implement in special purpose devices, but perfectly suitable for ordinary PCs. Learn more...
  • Adaptive limits
    A decentralized payment system must not depend on a single person's decisions, even if this person is a developer. Learn more...

Plus, a set of features that will be introduced:

  • Integration API
    LeviarCoin daemon and DRMoB system communication is achieved by sending and receiving encrypted commands on the default port:const int DRM_NETWORK_DEFAULT_PORT = 19002;
  • Anti-Fraud/Cheat System and DRMoB
    Is an anti-tamper technology and Digital Rights Management over Blockchain (DRMoB) scheme.
    As well as to protect software integrity, is designed to prevent players of online games from gaining unfair advantage through the use of third-party tools.

    Why LeviarCoin:
    • Blockchain is immutable, changing the history requires too much effort compared to benefits
    • High availability, virtually infinite scaling
    • Blockchain is cheaper to use than known DRM servers
    • Everyone holds a copy of Blockchain and no one "owns" it

Integration API

Integration API is a set of new commands bundled into the LeviarCoin daemon.
Its main purpose is to create an encrypted connection to the DRMoB Layer and directly serve required data to the user.

This is an example to better understand the purpose and how easily developers could use these commands:
./leviarcoind --iapi command *yourapikey* args
Initial available commands will be:

  • getnewkey is the only command that works without providing a valid key, the system will generate a new key associated to your address.
    Returns a JSON object:{ "success": true, "code": 200 }
  • storetransaction accepts a Base64 encoded string (max 512 bytes) that will be encrypted with your key and stored on blockchain
    Returns a JSON object:{ "success": true, "code": 200, "id": "4fd6c8b6a9cc3b0f9d8a87ae21eb9fc7" }
  • readtransaction accepts an "id" in order to retrieve a previously stored transaction.
    Returns a JSON object:{ "success": true, "code": 200, "data": "previously_stored_data" }

Anti-Fraud/Cheat System and DRMoB Layer

Every software and gaming company dreams to make their products and data as secure as possible using Activation servers, DRM servers, Anti-cheating software, etc. but these protections too much times get hacked or bypassed, for almost all softwares and games, in fact, you can find illegal keys and/or cracked executables (like EXEs, APKs, IPAs).

Our final goal, by creating this tool, is to make available to software and mobile apps developers, a library to prevent these frauds.

Our timeline
