You can join us on our journey by taking part in our ICO on July 25th. Early adopters can get a 30% bonus on their initial investment in the public pre-sale.
The eSports industry is growing at a phenomenal rate, with nearly a doubling of players expected worldwide by 2020. We think this industry is currently like those early Olympic games, full of promise and potential. We want to provide a service that encourages more gamers to treat their sport like marathons. To do this we are implementing a blockchain system in our ICO this month, which you can read more about here.
Joining our 10,000 players is easy. First sign up with us at Yamzu, then create and verify an account. After this, add us on your game client of choice. Once this is done you can create a tournament with us, choose the stakes for entry and join from your game client. Our web servers will then host the competition so you can focus on playing at your highest level.
Ludos Tutorial Number 2: The Concept of Oracles on Blockchain Explained
contracts, agreements written in code which get activated when
predetermined conditions are met, are turning out to be one of the most
revolutionary applications of the blockchain. Through smart contract,
users including smart devices in the Internet of Things (IoT) networks,
can interact and perform business transactions with one another without
the third party enforcer services.
a simple smart contract, an action of one of the counterparts triggers
an activation. For example, the receipt of payment into an account can
trigger a file to be sent to the sender of the money. The payment could
also trigger a product shipping procedure.
complex smart contracts however might require to be activated by data
streaming external to the blockchain on which they are launched. For
example a betting decentralized application on the blockchain might rely
on the outcome of real world game matches to determine winners and
A smart contract on that decentralized application needs to
be tapped on to make payment to those who make accurate predictions.
This can only happen if it receives accurate results of the matches in
The role of oracles
This is where an oracle comes into play.
oracle is a node, a platform or a channel that stands between the
blockchain and the outside world. Its’ primary function is to relay data
which is necessary for the execution of smart contracts from outside
into the blockchain. The particular oracle for use is coded into the
smart contract itself.
blockchains use the oracle in their respective ways. Some blockchains,
such as Ethereum, use third party oracle services. These are separate
projects that connect to it through Application Programming Interfaces
(APIs). The third party oracles can be decentralized like the platform
Chainlink or centralized like Oraclize.
some blockchains have the oracle functionality coded into their base
protocol. Ludos is one of those that belong in this category, making it
more decentralized as a service platform.
oracle designs are more in line with expectations of the majority of
users especially within the crypto space. This is because users do not
have to worry about compatibility issue. Furthermore, the functionality
is well thought of right from the foundation of the platform.
Incentives to provide good data
both centralized and decentralized oracles, it is the individuals who
are tasked with sourcing for data and feeding it to smart contracts that
need it. This might appear as a weak point since individuals can choose
not to provide the correct data.
in most architectures this concern is taken care of and handled through
robust game theory models. Akin to the maintenance of blockchain
themselves, in oracle designs, good actors are rewarded and those who
try to game the system are penalized.
most instances, those providing data through the oracle system are
required to stake value in the form of native coins. If they share the
correct data, they stand to receive a reward and get back their staked
coins. However, if they provide the wrong data, they are not rewarded
and also risk losing the money staked.
The Platform is intended to allow video game publishers to maintain their own in-game credits on the NEM blockchain. This is made possible upon after the video game publisher downloads the Xarcade SDK from the platform and integrate it. The Platform enables users to exchange, purchase and transfer the in-game credits, which
would be accessible from: (a) The desktop; (b) Mobile devices; (c) An in-game browser window.
The Platform facilitates the buying of in-game credits and in-game products with XAR, enabling users to purchase “outside” of the game. The Platform supports game publishers to create an ecosystem of spending and earning by paying through a two-way exchange ability model, and circumvents the requirement of in-app purchases for game points, so that game publishers do not need to rely on payment solutions such as Google/Apple in-app payment solutions. XAR can be used to buy XEM, however XEM can only be exchanged through the use of XAR, which is effectively the “gateway token,” for all users on the Platform. XAR can also be purchased on designated exchanges or purchased directly from the Platform. Users must purchase XAR for in-game purchases. Accumulated in-game tokens can be exchanged for XAR. Platform users may use the NEM universal e-wallet and the SDKs will automatically detect the e-wallet once it is in tegrated into a publisher’s game.
