.bit SubDIDs are live!

What are SubDIDs?

Similar to DNS, each .bit can have its own SubDID. For example, if you own satoshi.bit, you can mint 001.satoshi.bit, etc. In this case, 001.satoshi.bit is a SubDID of satoshi.bit.

SubDIDs have the following features.

  • Low cost, almost zero
  • Unlimited minting
  • Completely independent. SubDIDs have the same functions as the main .bit accounts

Compared to a main .bit account, SubDIDs can be used in a wider range of scenarios, especially for DAO, NFT communities, etc.

Usage scenarios

  • DAO: membership, voting weight credentials, contribution record, receiving airdrops

DAO organizers can distribute unique SubDIDs to each member based on when they joined. Admins can obtain basic information of members, including Twitter, Discord, address, etc. via all SubDIDs of the organization. Through the basic information of the members, admins can analyze the members’ participation in DAO activities, their contributions to DAO, etc., and arrange tasks and assign voting weights according to the members’ contributions. The manager can also analyze the ability and contribution of each member via SubDIDs, formulate a corresponding reward scoring system, and distribute corresponding rewards for members, which can be directly distributed through SubDIDs.

To ensure fairness and transparency, DAO can write the rules of SubDIDs distribution into the contract in advance.

For example, PeopleDAO can distribute xxxx.peopledao.bit to all members.

  1. The organization only allows the first 5,000 members to join. The first member is 0001.peopledao.bit and the last one is 5000.peopledao.bit.
  2. 0999.peopledao.bit has served as the community AMA moderator several times and has facilitated the operation with several projects. PeopleDAO has awarded 1,000 $PEOPLE to 0999.peopledao.bit.
  3. PeopleDAO can develop a reward system based on members’ contributions and then distributes $PEOPLE airdrops. $PEOPLE will be distributed directly to the member’s address via their SubDIDs.
  4. PeopleDAO sets corresponding voting weights for different SubDIDs according to members’ responsibilities.
  5. PeopleDAO members change their names to xxxx.peopledao.bit to promote the PeopleDAO anywhere and anytime to attract more people. At the same time, members will also have a deeper sense of identity and belonging to the PeopleDAO.
  6. PeopleDAO holds events. Admins do not need to collect winners’ information separately. They can collect members’ information via their SubDIDs directly and distribute the rewards.
  • NFT Community: Verifiable PFPs - NFT + DID

Today’s PFP NFTs are often right-click copied and are often easily counterfeited. Purchasers/collectors are often easily cheated due to the difficulty in distinguishing the true author. Because of the extremely low cost of theft and the high profit of a successful sale, thefts are frequent and there is nothing the victim can do.

Surprisingly, SubDIDs can effectively solve this problem! NFT+DID will become a verifiable PFP. For example, when Loot sells NFT, Loot can distribute a corresponding SubDID to each buyer at the same time. Buyer A will receive 0001.Loot.bit at the same time as he buys Loot#0001 NFT.

  • Proof of attendance, event commemoration

A SubDID can be used as an on-chain proof of attendance, which is not only a simple credential but also has all the capabilities of a DID. Organizers can distribute SubDIDs as commemorative credentials to all participants at the event.

For example, the International Olympic Committee can distribute commemorative credentials to all athletes who participate in the Olympic Games. E.g. janes.olympic2024.bit, kite.olympic2024.bit, jack.olympic2024.bit. If Jack participated in the 2018, 2020 and 2024 Olympics, he can get jack.olympic2018.bit, jack.olympic2020.bit, jack.olympic2024.bit.

Additionally, Jack can manage these SubDIDs with his address. When a new coach or teammate wants to know about Jack’s past competition history, they can access all the SubDIDs of Jack. Not only that, but they will also be able to learn more about Jack’s achievements and experiences through these SubDIDs.

  • Clubs, Star Fan Clubs: Verifiable Tickets on the Chain

Fan clubs often host a variety of activities. Selling and verifying tickets are critical links, and they often choose to look for a third-party company to take charge of this part. In fact, SubDIDs can be sold as tickets and entry credentials, with the ability to easily set prices and quantities.

For example, the 2026 FIFA World Cup will be held soon. The spectator seats are divided into 15,000 seats in General I area, 30,000 seats in General II area and 5,000 seats in VIP area, with different prices for different areas. At this time, the organizer can set the number of SubDIDs and the price as follows.

Spectator seats Tickets Number Price($)
VIP area VIP0001.2022FIFA.bit ~ VIP5000.2022FIFA.bit 5,000 2,700
General I area GI00001.2022FIFA.bit ~ GI15000.2022FIFA.bit 15,000 2,000
General I area GII00001.2022FIFA.bit ~ GII30000.2022FIFA.bit 30,000 900

When the audience enters the stadium, they only need to verify their SubDIDs. Moreover, fans can also gain a unique fan identity after watching an exciting competition.

More scenarios: a symbol of honor for the project, Gmail for Web3.0, managing multiple addresses in the same chain for individuals, etc…
