The computer games industry is usually ahead of the curve when it comes to the introduction of new information technologies.allother areas of application, including even targeted ones, the solution of tasks of which usually becomes the cause of breakthrough technologies. Blockchain technology is no exception.

Augmented reality is like technology, havingquite serious and responsible target areas of application, such as education, the design of complex systems and others, nevertheless are developing at a faster pace in the gaming industry.

Gaming User Needscreate incentives for the industry to develop and produce increasingly powerful graphics cards, and gaming computers can compete in performance and cost with computer systems used for professional work with sound, video and other complex computing tasks.

Blockchain technology designed to solve the most complexSocio-economic problems, which are potentially the basis for the new global financial system, were also not ignored by game developers and players.

Given that blockchain is always a bit "about money", blockchain games predictably causeinterest from virtual casinos, and their smart contract fairness expandsaudience at the expense of those who are usually not inclined to believe the organizers of the games.

The use of cryptocurrencies in computer games,non-gambling, inevitably arouses the interest of a huge community of players and increases the popularity of such toys for those who prefer to bet on their skills and gaming experience, choosing computer games in which the result depends on the actions and decisions of the player, rather than a random number generator .

The first cryptocurrency games exploited the possibility of instant automatic payouts, without having any advanced game script and gameplay graphics.Instant lotteries, in which the player made a guess or choice, which in the second stage was compared to the value given by a random number generator - the most famous representative was the game Satoshi Bones, were developed in multiplayer lottery-type games involving several players who place their bets by disassembling the items offered by the game.Then, again, the winner or loser was randomly determined, whose bet was divided among the rest of the participants.

2017, passed under the sign of the ether, brought ussmart contract games related to the purchase and sale between players of certain entities created within the game. A high-profile event for the entire cryptocurrency community was CryptoKitties, which at the time of their take-off at the peak of interest actually blocked the Ethereum network.

After crypto kittens, the world saw many similartrading games, but, strangely enough, all kinds of crypto pyramids gained popularity. The players were not deceived by the essence of the game and its pyramidal design, but they experienced, participating in them, their ability to enter on time and exit on time.

Increased attention to games with cryptocurrencies was shown by online casinos, which, again, were attracted by the possibility of instant draws with automatic distribution and withdrawal of winnings at a new stage of technology development.Structurally, most of the games with cryptocurrencies that fill the catalogs of online casinos are not much different fromschemes implemented in slot machines, but, perhaps, nothing more sophisticated is required for casino players at this stage.

The gaming use of blockchains deserves to be taken seriously, as it creates additional needs for cryptocurrencies that the industry needs and givesA wide field for developing skills in working with crypto, wallets, and smart contracts.

In addition, the demand for blockchain toys is causingthe need for blockchain developers and sets interesting tasks for them. Since in game applications, the developer’s imagination is the only limiter, in the process of working on the game the most exotic options for the use of smart contracts arise and are developed. Moreover, the result of the development does not lie on the table, but is broadcast to a wide audience.

Despite the seemingly frivolity of the gameCompared to trading, mining, investments in cryptocurrencies, blockchain toys, directions can do more to expand the user experience than educational literature, courses, and journalism in specialized media combined.

Perhaps the best thing that can be done today for the development of the cryptocurrency market is to promote the popularization of blockchain games that use cryptocurrencies.Blockchain games can become an entry point into crypto for the general public.Through games, the experience of managing tokens and handling cryptocurrency wallets is acquired quickly and naturally.Buying tokens as an investment is often just one or two transactions, while the game requiresnot only frequent transactions, but also mastering tools like MetaMask — yes, it's easy, but to master it, you need a reason that givesCryptoKitties and other games on the Ethereum blockchain.

A separate new type of game with the development of blockchain technologies is toys that do not require a game server — current game data is stored and recorded in the blockchain, the gameplay is implemented in JavaScript and unscrewed in the user's browser.The logic of the game is hardwired into the smart contract and does not allow even a theoretical possibility of circumventing the rules.At the same time, the cause-and-effect relationship "winning — receiving a win" is realized immediately after the occurrence of the corresponding event.

Of course, not everything is so easy and simple — to interact with a gaming smart contract on the Ethereum network, you need to install the MetaMask browser extension, transactions that record players' "moves" in the blockchain requireBut these inconveniences are more than compensated by the economic component of the game — the winnings are quite material even in the simplest toy, for example, which requires you to guess in which hand ether is hidden.

By the way, a feature of this type of games isthe ability to create an unlimited number of game scripts for one smart contract, which opens up a wide field of activity for developers writing in JavaScript.

As an example, let’s give a diagram of a game in which you can fill the face of an opponent or get from him and, accordingly, pick up his bet or lose yours.

The web component of the game runs in JavaScript and is available for download.Once hosted on a website, it accesses the game's smart contract via MetaMask and launchesby transferring a certain amount of ETH to the smart contract address.

ScriptImplementFist Fight – ParticipateTwo players who take turns hitting each other and defending againstVictory is awarded by points, and the game bank is divided accordingly.A developer fee of 10% of the loser's resignation remains on the smart contract.

The smart contract provides for the participation of two more parties in the game, in addition to the developer of the smart contract — the owner of the site on which the game script is launched, and the author of the script.The commission accumulating on the smart contract is periodically reset to two ETH addresses transmitted to the smart contract by the game script via MetaMask.

Ability to change the ETH address for the ownersite (publisher) can be described in the documentation for the game, posted on the developer's site. To localize the script for a specific site, so that it starts to earn the commission provided for publishers, you need to replace the ETH address specified by default with your own.

The possibility of changing the second address is not described ininstructions, but any JavaScript programmer who knows the slightest bit can do this or write his own script, by analogy with the original. Such an opportunity should not scare developers, since their interests are protected by a smart contract.

In fact, the construction of a smart contract is an invitation for developers to write their scripts for this smart contract and for webmasters to post a scriptgames on their sites.

As an example of the variety of gameplay on one smart contract, you can cite the option of playing on the same smart contract, but in a different surroundings.

Instead of fighters, there is a goalkeeper and a football player who takes a penalty.The same logic as in the original - one attacks, the other defends, but in a different gameplay.Smart ContractScript receivesThe hash of the choice of the defended goal zone is the same as in the ring combat variant, 2 of 4, and the hash of the choice of the direction of the shot is 1 of 4.If there is a match, the goalkeeper wins, if there is a mismatch, the ball hits the ballinto the goal and the penalty kicker wins.

Participation in the game is initiated by transferring toa smart contract of a certain amount of ETH, for example, 0.1 ETH by the first player to stand on the gate. The offer to play is open to anyone willing to take on the role of the penalty taker, who also transfers 0.1ETH to the smart contract address when accepting the challenge.

The win is calculated from the difference of goals scored and the player missed, the commission is divided between the developer of the smart contract, the author of the script and the webmaster on whose website the script is launched.

Such games are quite simple to implement and attractive with the opportunity to win in cryptocurrency. And also, a guaranteed reward for developers.

While there are few games made in this way,but given their incredible simplicity, guaranteed honesty and the possibility of earning money for all participants, we can assume that the game pool will grow like an avalanche, and with them the number of people who know firsthand cryptocurrencies, cryptocurrency wallets, cryptocurrency exchanges and other industry services.
