The Spirit NFT

We applied the Soulbound concept in PhalaWorld and created Spirit NFT🧠. Spirit is a non-transferable NFT generated with survivors‘ unique on-chain identities, which are coupled with a Decentralized Identity protocol called My Crypto Profile (supported by Litentry). This article will explain everything about Spirit NFT in detail.

Why do we need Spirit NFT?

In the Web 3.0 world, what represents a person's achievement? It's not how much money you own, it's what you have built.
Vitalik Buterin published the “Soulbound”, and emphasized the concept of “proof of attendance” derived from World of Warcraft. Players need to conduct certain behaviors to acquire the most powerful Soulbound items, rather than simply buying them with money. We agree with this idea, and believe that PhalaWorld should be predicated on the same Soulbound concept. User behavior is a very valuable asset in Web 3.0, which can even represent a user in the metaverse. Therefore in PhalaWorld, we designed Spirit NFT to represent much more of who you are, not just what you can afford.

What is Spirit NFT?

Spirit NFT is a Soulbound concept NFT in PhalaWorld. Each user can receive a free-mint Spirit at any time, the only condition being that users must contribute in Phala (with attributes above 0).
Users can only upgrade their Spirit by contributing to the Phala community constantly or taking part in the Phala ecosystem. Users can find ways to level up their Spirit in the next article in the Spirit NFT series. There is no way for users to obtain attribute enhancements through ordinary purchases.
The Spirit is non-transferable, and one user can only claim one Spirit, meaning this Spirit will accompany users throughout their entire PhalaWorld experience. One Spirit can equip different Shells however, similar to how a person can change clothing.

Spirit Careers

In PhalaWorld, there are four unique attributes and five different possible careers. The attribute value is stored in Spirit, and the user's different behaviors determine the value of these attributes. The distribution of different attributes determines which career the user is the best suited for. Users can choose the most suitable career according to the system’s recommendation when minting their Shell, and different careers will also be reflected in the appearance of their Shell.
Once a career is selected, it cannot be changed. User can only buy a new Shell if they want to try another career.
Career
Career Introduction
Hardware Druid
Outstanding Hardware Druids can customize their own robots to match their characteristics. Intelligence advantage.
Robo Warrior
Mechanical strength determines the Robo Warrior’s fighting ability no matter which species they are. Strength advantage.
Trade Negotiator
Trade Negotiators are a relatively common group, but they play the most important role in trade and are the core of the circulation of wealth, goods and money. Dexterity advantage.
Hacker Wizard
Fascinated by the power of controlling the elements, some engineers began to call themselves "Hacker Wizards", which can change the world in your eyes. Intelligence advantage.
WEB3.0 MONK
Monks' understanding of Web3 and the graphene algorithm is far superior to that of ordinary people. Willpower advantage.

Spirit Attributes

Spirit has a unique mechanism for attributes and their growth. The next article will explain the numerical conversion of attributes. In PhalaWorld, each behavior corresponds to different attributes, and executing different behaviors will add points to different attributes. PhalaWorld will show the best matches between the avatar's attributes and different careers.
Attribute
Attribute Introduction
Dexterity (DEX)
Affected by on-chain frequency-related behavior
WillPower (WILL)
Affected by advocate behavior
Intelligence (INT)
Affected by tech/hardware related behavior
Strength (STR)

How to inject data into Spirit?

User data has been acquired using a cooperation with My Crypto Profile (MCP) project, the PoC application of aggregated identity developed by the Litentry team. MCP is a decentralized Web3 personal data management tool designed for users to aggregate and manage their personal data in both Web 2.0 services & Web 3.0 blockchains and decentralized storage systems.
Starting the claim, users will be directed from the PhalaWorld registration page to MCP to link accounts and generate their aggregated on-chain identities, which will be injected into Spirits. Required entries, including Phala Network, Khala Network, Polkadot, Discord, Github, Twitter, etc. are listed in users’ PhalaWorld page. After registration and officially becoming a survivor, users can check their injections and add, delete, update, and maintain their given entries on MCP at any time.
More than one decentralized account can be aggregated in one DID. The more accounts you link, the more three-dimensional and fuller users' images will appear, and the higher level users' Spirits will achieve. When multiple accounts are linked, PhalaWorld will automatically select the best value of the same action to inject into the Spirit.
