随着被喻为Meta系三大公链之一的Sui主网在香港时间5月3日晚上8：00上线，愈来愈多游戏生态陆陆续续走到Sui 的生态网发展。根据非官方资料，SUI 现时有大约25个已知的GameFi 项目发展中，未来亦会有多更GameFi 大作例如Project Eluüne、Abyss World、或者轻松小品游戏如Cosmocadia、Run Legends、甚至是笔者有份参与的动作策略卡牌游戏Legend of Arcadia，都已经宣布将会在Sui上部署，到底Sui有什么魅力能在短时间内吸引了GameFi项目研发呢？

以游戏作为发展定位(Game-first approach)

Sui 开发公司Mysten Labs 的游戏合作伙伴关系主管Anthony Palma 曾经接受Decrypt采访时提到, 现时Sui 已经跟40 多家的游戏项目方合作中并建构中，Sui 的定位不仅是追求「区块链游戏」或「加密货币游戏」，

而是追求那些通过利用web3 提升玩家体验及高交互性的优质游戏。不谋而合地，Palma 对于GameFi 赛道的看法跟笔者十分相近，都认为所谓的web3 游戏怎样演变也好，「游戏」的部分永远都是走在任何其他元素之前。因此，作为一条新星的Layer-1 公链，其中两大设定特性都是专门为GameFi 赛道而生。

另外，我们也可以期待在6月底IVS Crypto 2023 活动举办期间，Sui Network 与Jump Crypto 共同举办的Kyoto Builder House 活动中也将有不少GameFi 团队参与，由于日本本身就是游戏大国，想当然也有非常多游戏团队有所兴趣，对于GameFi 的关注度自然也会提升不少，就让我们拭目以待。

NFT链上数据存储(On-chain Data Storage)

跟我们熟识EVM 公链部署的NFT稍为不同，Sui 链上的游戏NFT metadata 并不是存储在IPFS 系统或中心化伺服器，而是以一个「Object」的代码层形式存储在链上，并由Move 这个智能合约编程语言所控制。好处是Sui 链上NFT 资产在某种层面真真正正实现了去中心化，所有关于NFT metadata 的资讯都能通过链上查阅，而项目方亦不能单方面随意改动。当然，相对应所牺牲的是，把游戏NFT 所有资讯都搬迁到链上存储处理，意味着该NFT 的属性每一个改动(例如把一只火属性NPC 增添一个光属性)，都必需经过NFT 持有者的授权允许能成立，除了gas fee 之外，无疑用户体验(User Journey)多多少少都会受影响, 此处就不详解了。

动态属性更新NFT (Dynamic-updated NFT

注：此处只作解释用途，原设定的玩具英雄移有度(Rarity)是不能被更改的

本月17日，Sui Foundation 其中一位开发成员0xShayan在一个Web3 Gaming Week座谈会上，曾经用Pokèmon 的进化系统解释Sui 独有的动态属性NFT 设计。延伸上述所提及的「Object」设计，Sui 链上的NFT智能合约由两部分造成，分别是「Fields」及「Dynamic Fields」。前者是由最少6项属性展示代码标准(Object Display Standard)所制定，以厘定该NFT 系列的基本资讯，例如NFT collection的名称、图像URL、创作者等等，通常在Fields 的NFT 属性是不能被更改的； 后者则容许被建立在一个「Field Object」之后，此处的NFT 属性是可以通过玩家授权后能作出更改。

以Legend of Arcadia 为例，游戏内的每一位玩具英雄都是NFT 资产，能通过消耗闲置的玩具英雄，把身上的部件继承到目标玩具英雄。若果在现时的EVM 链的做法做(如左图所示)，原本那张的目标玩具英雄NFT A 需要被烧毁，中心化伺服器会根据被消耗的闲置玩具英雄内容，重新铸造一个新的玩具英雄NFT B，并把内容继承过去。相反，因为Sui 链的动态属性NFT 特性，能允许同一张的目标玩具英雄NFT A 直接更改身上的部件，而需要再通过烧毁及铸造来实现。

这样做法的好处是，NFT 资产的持有者的归有权由始至终都是紧握手中，更重要的是如游戏NFT 资产在短时间内需要频密地更新属性， (例如一把火之剑每杀一个敌人攻击加一) 该NFT 资产并不需要经历多次烧毁铸造，而只需要通过动态属性去改变便可，不但减轻了项目方伺服器的负担，同时能真正实现去中心化及数字拥有权(Digital Ownership)。

区块链游戏生态链

由于笔者也是Legend of Arcadia 其中一位核心成员，有幸每周定期都会跟Mysten Labs 的技术团队交流学习，除了能深深体验到对方在区块链智识领域上的独特见解外，更重要的是他们非常热情及无私地提供各方面的技术支援。团队深知以Move 智能合约编程语言设计的Sui 最大障碍就是非EVM兼容(non-EVM compatible), 很多游戏项目方的研发人员都为了舍难取易而去选择其他EVM 兼容的公链发展。正因如此，他们更加需要主动伸出援手，吸引更多优质GameFi 项目发展，打造属于Sui 的游戏生态，这就是笔者一直强调的是二级市场看到的另外一面。

As the Sui mainnet, known as one of the three major public chains in the Meta series, was launched at 8:00 pm on May 3, Hong Kong time, more and more game ecosystems are gradually coming to Sui's ecological network. develop. According to unofficial information, SUI currently has about 25 known GameFi projects under development. In the future, there will be more GameFi masterpieces such as Project Eluüne, Abyss World, or light-hearted sketch games such as Cosmocadia and Run Legends, and even the author will participate in it. The action strategy card game Legend of Arcadia has already announced that it will be deployed on Sui. What is the charm of Sui that can attract the development of GameFi projects in a short period of time?

Taking games as a development position (Game-first approach)

Anthony Palma, director of game partnerships at Sui development company Mysten Labs, once mentioned in an interview with Decrypt that Sui has now More than 40 game project developers are cooperating and building. Sui's positioning is not only to pursue "blockchain games" or "cryptocurrency games", but also to pursue those who use web3 to improve player experience and High quality game with high interactivity. Coincidentally, Palma's views on the GameFi track are very similar to the author's. They both believe that no matter how the so-called web3 games evolve, the "game" part will always come before any other elements. Therefore, as a rising star of the Layer-1 public chain, two of its major settings are specifically designed for the GameFi track.

In addition, we can also look forward to the participation of many GameFi teams in the Kyoto Builder House event co-organized by Sui Network and Jump Crypto during the IVS Crypto 2023 event at the end of June. Since Japan itself is a game Of course, in a big country, there are many game teams who are interested, and the attention to GameFi will naturally increase a lot, let us wait and see.

NFT On-chain Data Storage

Slightly different from the NFT deployed on the EVM public chain that we are familiar with, the game NFT metadata on the Sui chain is not stored in IPFS The system or centralized server is stored on the chain in the form of an "Object" code layer and controlled by Move, a smart contract programming language. The advantage is that the NFT assets on the Sui chain are truly decentralized to a certain extent. All information about NFT metadata can be viewed on the chain, and the project party cannot unilaterally do so at will.Will change. Of course, the corresponding sacrifice is that all the information of the game NFT is moved to the chain for storage and processing, which means that every change in the attributes of the NFT (such as adding a light attribute to a fire attribute NPC) must be maintained through the NFT. If someone's authorization is allowed, in addition to the gas fee, the user experience (User Journey) will undoubtedly be affected to some extent, which will not be explained in detail here.

Dynamic-updated NFT

Note: This is for explanation purposes only. The original Rarity of the toy hero cannot be changed< /p>

On the 17th of this month, 0xShayan, one of the development members of Sui Foundation, used Pokémon’s evolution system to explain Sui’s unique dynamic attribute NFT design at a Web3 Gaming Week symposium. Extending the above mentioned "Object" design, the NFT smart contract on the Sui chain is composed of two parts, namely "Fields" and "Dynamic Fields". The former is formulated by at least 6 attribute display code standards (Object Display Standard) to determine the NFT The basic information of the series, such as the name of the NFT collection, image URL, creator, etc., usually cannot be changed in the NFT attributes of Fields; the latter is allowed to be created after a "Field Object", where the NFT attributes Changes can be made with player authorization.

Take Legend of Arcadia as an example. Every toy hero in the game is an NFT asset. By consuming idle toy heroes, their parts can be inherited. to the target toy hero. If the current EVM chain method is used (as shown on the left), the original target toy hero NFT A needs to be burned, and the centralized server will use the consumed idle toy hero content. Recast a new toy hero NFT B and inherit the content. On the contrary, because of the dynamic attribute NFT characteristics of the Sui chain, it can allow the same target toy hero NFT A to directly change the body parts, without the need to burn and cast it. To achieve.

The advantage of this approach is that the ownership rights of NFT asset holders are tightly controlled from beginning to end. More importantly, game NFT assets require frequent transactions in a short period of time. The attributes of the NFT asset do not need to be burned and cast multiple times, but only need to be changed through dynamic attributes, which not only reduces the load on the project server burden, and at the same time can truly achieve decentralization and digital ownership (Digital Ownership).

Blockchain Game Ecological Chain

Since the author is also one of the core members of Legend of Arcadia, I am fortunate to communicate and learn with the technical team of Mysten Labs regularly every week. In addition to being able to deeply experience each other's work in the blockchain In addition to their unique insights in the intellectual field, more importantly, they are very enthusiastic and selfless in providing technical support in all aspects. The team is well aware that the biggest obstacle to Sui, which is designed with the Move smart contract programming language, is non-EVM compatible. Many game project developers choose other EVM-compatible public chains for development in order to sacrifice the hard and the easy. Because of this, they need to proactively lend a helping hand to attract the development of more high-quality GameFi projects and create a game ecosystem belonging to Sui. This is the other side of the secondary market that the author has always emphasized.
