An Overview of the Blockchain Games Stands Out from the Oasis Hackathon Shanghai Chapter
On September 22, 2019, Game Oasis Hackathon Shanghai Chapter was successfully concluded at the beautiful Bund of Shanghai, which was co-hosted by Binance Labs, Cocos-BCX, Celer Network, Contentos and Math Wallet, with 11 teams competing in the final round.
After the 48-hour all-out hacking, 11 developer teams submitted their final works under the challenge of Interoperability, which requires developers to build a game on top of one of the public chains including Cocos-BCX, Celer Network and Contentos and finish their works within 48 hours. The top 3 teams can receive ￥30,000, ￥20,000 and ￥10,000 respectively.
At the end of the event, Aurora Team won the first place, Babel Labs the second, while FAST and Blocklords won the third place together. In addition, Kuso Games won the Best Art Award and Krypton received the Best Original Game Award.
Below is a brief on the games developed by the 11 teams.
1. Unicorn Go
Unicorn Go is an H5 parkour mini-game developed by Babel Labs team on Celer. It has adopted the IPFS technology to reduce the costs of high-defense servers required by traditional games to prevent DDOS attack and of servers deploying web services. Gamers may start a quick match to begin the unicorn adventure with friends by paying GM coin, CELR, ETH or DAI. While the unicorns can run on their own, gamers need to tap or double-tap the screen to make the unicorns jump once or in succession for a higher score in a battle. The game has a completed real-time online battle system, which is cross-system, cross-platform, cross-chain and cross-transfer protocol, and is based on Layer 2 (Raiden Network) and enables user match.
Fast is a team from Shanghai and developed two games during the hackathon. One of them is Farmo, a MOBA (multiplayer online battle arena) for gamers to plant crops. Gamers can spend 1 COCOS/COS/EOS to plant crops on idle farmland. The crops will contain 50% of the value of the TOKEN initially and will continue to grow up to 50 times the value of the TOKEN. However, there are also chances that the crops explode when the value reaches 1 time, so gamers have to harvest them before the explosion. The game has adopted the team’s self-developed cross-chain transaction technology. Currently, it is available on Cocos-BCX, Contentos and EOS blockchains, and enables cross-chain battles within one server. Gamers from different chains are playing in the same scene, solving the problem of cross-chain interoperability and interaction.
While the other game of Fast is Space Crush, a battle game based on Celer.
3. Oasis Protocol — Cross-Game Assets Transfer Protocol
“Infinity Gamer” is a team from the department of computer science of Zhejiang University. Their work, Oasis Protocol, is a cross-game asset transfer protocol for developers. That is to say, an item (on-chain) in Game A can be transferred and used in Game B (on the blockchain). For now, the protocol is based on Ethereum. The team has demonstrated at the Hackathon how to transfer crypto kitties in the Crypto Kitties Generator to Cat Knight. The protocol is completely based on smart contracts; therefore, the overall assets transfer logic is also done on the chain, without any off-chain operation.
CoinRaiders is a 2D loot fighting battle royale game developed by BlockLords team from Shanghai on Cocos-BCX. Gamers can use CocosPay to log in and will support login with almost all the major wallets in the future. Although the current version supports COCOS only, the future versions will support all the major digital currencies for interoperability across blockchains. Gamers may log in with their familiar wallets and stake tokens to enjoy the fun of battle royale game and loot other gamers’ tokens.
5. Rookie Camp
Rookie Camp is a 3D multiplayer online TPS shooting battle game developed by Orange Tabby team from Shanghai on Cocos-BCX. The team used the Unreal Engine to complete the building of the game. Gamers can log in the game using Cocos Wallets to win on-chain items by participating in the battles. In addition, these item assets can circulate between games under the same Multiverse, that is to say, the item and prop assets are interoperable between games under the same Multiverse, including Star Hunter and project-Blemmyes.
6. Coin Girl Battle
The team “Kuso Games” from Beijing developed two games during the hackathon. One of them is a battle game called Coin Girl Battle, in which they designed the images of four coin girls respectively referring to Binance, Celer, Cocos-BCX and Contentos. The work is a 1v1 single-player battle game. Gamers have to pay tokens to start a battle and will receive the same amounts of blocks at random locations. Each block contains a random number of coin girls. Gamers need to control the coin girls to challenge the block of the other gamer. The game ends once either side occupies all the blocks. The whole process, as well as the result, will be recorded on the blockchain. While the other game the team developed is called All-Star Horse Racing, which is based on Cocos-BCX. The results will also be recorded on the blockchain.
7. Battle of Consensus
Battle of Consensus is a multiplayer real-time strategy battle game developed by Krypton team. It is a completely on-chain game. Each gamer needs to play a project and competes with other players’ projects in a limited area, trying to win more consensus points by dicing. Players are provided with several growth orientations to choose from, such as construction, army assembling and strategy card. The first to get 10 points will win the prize. The adoption of smart contract enables fair dicing results, decentralized awards settlement, as well as open and transparent game results.
8. Oasis Card
Oasis Card is a 1V1 card game called developed by Dgame Maker team from Shanghai. The game is based on Celer chain and has adopted the unified random number provided by Celer. Users’ cards can be seen by each other. There are mainly four types of cards: ordinary attack, defensive counterattack, power-up strike, and HP recovery. When one party’s HP decreases to 0, the other party wins. The scores will be uploaded to Celer blockchain after the game is over and the virtual currencies staked will also be transferred to the winners. The game ensures that the results will be recorded on the blockchain, while the whole gaming process takes place off-chain. In addition, gamers without any blockchain background can also play games through a centralized server.
WarWheels is a rogue-like game called developed by Aurora team from Beijing based on Celer and Cocos-BCX. It is reported that the team members are from a public company Cheetah Mobil. Gamers can fight against the NPCs by moving the joystick on the screen. The game has reproduced the unique elements of the FC game Red Fortress, such as helicopters and hostage rescue tasks, and has added modern weapons like RPG rockets and flame ejectors. The game mainly leverages Celer to enable PvP battles, while all the items in the game will be put on the Cocos-BCX public chain for asset trading.
10. On-chain Idol Mahjong
On-chain Idol Mahjong is a game developed by Genius Mahjong Girls team from Shanghai using Cocos engine and token system of Cocos-BCX. Gamers may log in the game with their wallets to redeem game coins in proportion by selecting a token and entering the amount they would like to transfer. At present, it only supports exchange on the Cocos-BCX blockchain. There are three gameplays in the game: Sichuan Mahjong, Taiwan Mahjong, and Room Card Mode. The results of each game will be recorded and settled on the chain.
CardSwap is a zero-friction cross-multiverse token swap game developed by New Story team from Shanghai. Based on the CocosCreator, ChainIDE and NHAS 1808 standard, the game is a game asset system independent of all other games. For gamers, there is a high entry barrier in terms of on-chain games provided by mainstream public chains. For example, gamers need to perform a series of complex operations to obtain the corresponding tokens through certain channels. With CardSwap, users can manage and transfer their assets in its interface, as well as set some basic Multiverse attributes. Gamers will be able to play the game on any public chain, as long as they possess BTC, BNB, COCOS, CELER, COS or any other tokens, which enables the perfect interoperation between all the public chains and games. The team specially produced two additional games to demonstrate their work. Take the card game CardAdventure as an example. If a gamer locks BTC assets through CardSwap, the default character of the card will be BTC one, and removing the corresponding color blocks will bring the gamer an additional bonus. After the game is over, the related “collectable attributes” of the game like the game results will cause a positive or negative premium of the NFT assets of the player in CardSwap, which can also be brought to other games, forming an interoperable loop.
