Sharing a game with a friend or a family member
was as simple as handing over a game cartridge.
This rare phenomenon for digital games is still
very common on other type of video games media
(e.g. game consoles). Sadly, this familiar feature is
not possible in most digital games for PC.
The existing distribution platforms for digital
games are a good opportunity for game
developers to make a profit from their hard work.
But those platforms take away a great piece of
the developers’ revenue for themselves (typically
30%). How can small dev teams grow in a good
pace if they are being held back by 30% in profits
wherever they publish their games at?
Moreover, some indie game developers
constantly struggle to finance their projects,
which is a barrier for their creations to come to
fruition. Although crowdfunding platforms like
Kickstarter or Indiegogo have help a few teams,
they don’t allow to fund a game project without
THE SOLUTION : THE LOTUS PROTOCOL
Lotus Core is a decentralized platform for
players, developers and investors built on top of
In Lotus Core, players will be able to
trade games with friends, developers will
earn 100% of the revenue derived from
selling their digital games, and also
receive funding from crowdfunding
campaigns within the platform.
A new way to register and distribute
When a game is purchased or loaned in the Lotus
Store, the Lotus Protocol creates a digital game
through a Smart Contract with a digital signature
and records it in the blockchain, which allows the
software developer to guarantee the authenticity
of each copy of software and giving players access
to their game even when the user is offline.
This way, Lotus Core seizes the opportunities
inside a new market of digital games traded
securely within the blockchain to represent the
ownership of property.
Ownership of software ...
In order to guarantee the ownership, Lotus Core provides an API to create unique cartridges in the
blockchain. The validity of cartridges will be given by the recipient address. This implies that the developer
will have a direct relation with the final user and consequently get 100% of the profits per sale.
Additionally, the cartridges will be digitally signed in order to allow the use of valid cartridges even in
This process is useful when someone wants to know the number of copies of a digital game and the history
of each one. It also serves as a customizable and convenient DRM protection system, allowing to use the
software in offline environments and write rules to share the software previously sold. These rules will
allow the final user to share or exchange her games:
Lotus Core provides a channel for communications between software developers and final users without
taking part in the sale process, making the software distribution a truly decentralized e...
In detail, the digital game will require a proof of ownership asking the user’s account to sign a random string
with the private key used to buy the game. Doing this will prevent the usage of valid cartridges by users
who did not buy the game. This proof is cheap in terms of computer resources and it can be required at any
time during the game execution in case of a malicious binary modification that skips the first verification.
It is important to mention that a signature can be verified with only the public address of the signer, but it is
impossible to generate a valid signature without knowing the signer’s private key.
Aiming to provide a truly decentralized experience Lotus Core needed to come up with a method for
players to download games in a way that it does not carry any associated costs to developers or to Lotus
Core. To accomplish this task we implemented the Lotus Decentralized Storage (LDS), a cloud-based
storage system for games running with a different token called Karma, wher...
To get a better understanding of how Karma will work, consider these conditions:
A player can download as many games as he/she wants as long as he/she has enough Karma to pay.
Players can gain Karma by:
Acting like storage nodes by lending an agreed amount of local drive space to the network.
Purchasing it on the Lotus Store.
Owning a game for certain amount of time.
Players can lose Karma by:
Purchasing games with Karma.
Execution or Launching Process
This is the core of the DRM system, using digital signatures plus the blockchain network to guarantee the
unicity and validity of a piece of software. When a game is launched or executed by a player, the compatible
applications will connect with the background process that verifies the blockchain and keeps record of the
player’s digital games.
Lotus Core allows players to exchange, gift, lend or sell digital games they own to other players, just like it’s
possible with most physical copies of games. Using the capabilities of Smart Contracts, we are able to write
rules to perform these actions and at the same time benefit developers in case of trades involving tokens.
Lotus Core offers developers the opportunity to fund their existing or new game projects using Lotus
Tokens (LTS), which serve as proof of investment. Developers who get funded will give a small percentage
of their revenue per sale to Lotus Core after launching.
If the goal is not reached then the invested tokens are returned to the original owner.
With these Smart Contracts, developers will also
benefit from these operations.
Games work in offline mode
Most of the DRM systems require an active
internet connection in order to check in real time
the ownership of the software. Using
cryptographic digital signatures we can check the
validity of any owned cartridge in offline mode.
Access to a new loan market
Having unique cartridges in the Blockchain plus
Smart Contracts allows us to tap into new
business opportunities like loaning systems: for
instance, we can write a program that gives a
cartridge to a player for a limited time and after a
while it automatically removes the cartridge from
the player’s library.
A fair DRM system
Using Blockchain assets plus the Smart Contracts
technology we can write rules that specify the
sale of a game is not a trade barrier for a free
market to emerge, allowing the game owner to
