A. Programmability

Everything in the Metaverse is represented by NFT. SBT is also a type of NFT. SBT will inherit all the characteristics of NFT. SBT can be static or dynamic; both programmable and intelligently interactive. The relationship between any SBT and other SBTs and NFTs can be an independent relationship, an equality relationship, an inclusive relationship, or a subordinate relationship. Using these characteristics of SBT, it is possible to effectively build an open, competitive and collaborative United Metaverse system (UMSYS.ETH).

B. Bindability

Bindability is to use SBT to bind other NFTs to effectively improve asset security, similar to the realization of multi-signature functions. Bindability determines whether NFT assets can be centralized or decentralized; NFT owners can freely choose whether the assets are anonymous or non-anonymous.

C. Transferability

The solution of some projects is to use SBT non-transferability, which may sacrifice the flexibility of SBT in order to achieve some functions, which is not a good solution. The transferability of SBT can be either bound state transfer or unbound state transfer. Its DID function is established through the binding state.

3. SBT solution

In May 2022, a paper titled "Decentralized Society: Finding Web3's Soul - Decentralized Society: Finding Web3's Soul" was published by Glen Weyl, a researcher at Microsoft's Office of the Chief Technology Officer, and Puja Ahluwalia Ohlhaver, a strategist at Flashbots. and Ethereum co-founder Vitalik Buterin. After the paper was published, a batch of projects and solutions appeared. Representative projects include: Optimism Collective, RabbitHole, Noox, Union Finance. This article focuses on the analysis of the Optimism Collective project. In addition to the above three characteristics of SBT, this project also has the following three advantages.

A. Platform advantages

OP Optimism Collective is built on the L2 of Ethereum, OPTIMISM, and can obtain the robustness and security of the Ethereum ecosystem as support.

B. Coding advantages

Optimism Collective uses a purely digital coding method, which is simple, intuitive, and more in line with the basic needs of the metaverse system to integrate with the real world. Digital codes can be supplied in unlimited quantities and have the scarcity of short numbers and good numbers. The pure digital SBT scheme may develop into a multi-functional new domain name system in WEB3.

C. The mode advantage

Optimism Collective first turns SBT into an ordinary NFT. Participants and builders can easily bid from the NFT market. Buyers can choose to bind with other NFT assets to realize the SBT function after purchase, or they can directly sell and trade in the market. Build market liquidity. This model can attract more people to participate in the system construction, and can also obtain rich NFT transaction fees and copyright income for the project party to achieve sustainable development.

2、SBT的特点 A 可编程性 元宇宙的一切都是以NFT为表现形式，SBT同样是NFT的一种，SBT将继承NFT的所有特点。SBT可以是静态的，也可以是动态的；既是可以编程的，也是可以智能交互的。任一SBT与其它SBT和NFT的关系可以是独立关系，可以是平等关系；可以是包含关系，也可以是从属关系。运用SBT的这些特性，可以有效构建开放型竞争并协作的元宇宙联合系统（UMSYS.ETH）。

B、可绑定性 可绑定性是用SBT与其它NFT绑定，有效提升资产安全性，类似于实现多签功能。可绑定性决定NFT资产可以中心化的，也是可以是去中心化的；NFT所有者可以自由选择资产是匿名的或者是非匿名的。

C、可转让性 有些项目的解决方案是采用SBT非转让性，这样可能是为了实现某些功能而牺牲SBT的灵活性，这并不是很好的解决方案。SBT的可转让性表现在既可以是绑定状态转让，也可以解除绑定状态转让。其DID功能是通过绑定状态确立。

3、SBT解决方案 2022年5月，一篇名为《Decentralized Society: Finding Web3's Soul - 去中心化社会：寻找Web3的灵魂》的论文发表，作者是微软首席技术官办公室的研究员Glen Weyl 与 Flashbots 的策略师 Puja Ahluwalia Ohlhaver 以及以太坊的联合创始人 Vitalik Buterin。论文发表后，出现了一批项目和解决方案，代表性项目有：Optimism Collective, RabbitHole, Noox, Union Finance。在这篇文章中着重分析Optimism Collective项目，这个项目除了具备以上SBT三大特点外，还有下面的三项优势。

A、平台优势 OP Optimism Collective是建立在OPTIMISM这个以太坊的L2上，可以获得以太坊生态的健壮性和安全性作为支撑。

B、编码优势 Optimism Collective采用纯数字编码方式，这种方式具有简单、直观、更加符合元宇宙系统与现实世界融合的基本需求。数字编码既可以无限量供应又具有短号靓号的稀缺性，纯数字SBT方案有可能发展成为WEB3中多功能新型域名系统。

C、模式优势 Optimism Collective先把SBT做成普通NFT，参与者与建设者可以非常方便地从NFT市场竞买，买家可以在购买后选择与其它NFT资产绑定实现SBT功能，也可以直接在市场中贩卖交易来构建市场流动性。这种模型可以吸引更多人参与系统构建，也可以为项目方获取丰厚的NFT交易费用和版权收入，实现可持续发展。
