Crypto Collectibles have been gaining popularity since the launch of CryptoKitties last November. The popular blockchain game implements the ERC-721 Non-Fungible Token (NFT) standard. NFTs are like baseball cards on the blockchain.

The NFT standard is significant beyond gaming. It can represents things like land deeds, certificates, diplomas, or receipts. The ERC-20 standard has one advantage, though. Governance.

ERC-20 tokens are useful for 1 token : 1 vote models. Their supply represents their voting weight. Someone controlling one thousand tokens controls one thousand votes.

By their nature an NFT’s value differs from its peers. Some baseball cards are more valuable than others. If we form an organization based on our assets how do we determine which assets have the most votes?

Every NFT consists of the same properties. We could come up with a scoring system based on their attributes. Each asset’s total score becomes its voting weight.

The CryptoKitty Collectors Club

We want to form a club based on our CryptoKitty holdings. Together, we decide to assign a score based on each kitty’s attributes. Rare attributes receive 10 points, common attributes receive 1.

The rarest kitties award the greatest number of votes.

We deploy a DAO contract that uses each member’s asset scores to determine their total votes.

Shared Ownership

Voting weight provides a means for property owners to self-govern. When leasing or sharing ownership of their property an asset’s weight may split. Shared weight may vote in a DAO.

A skyscraper owner assigns asset weight equal the building’s square footage. As they lease parts of the building they assign weight equal to the square footage to lessees.

A DAO vote arbitrates internal disputes between leasees and property owner.

I Gave

This idea came from our project — I Gave. We issue ERC-721 tokens to commemorate charitable giving. We will honor these donations as votes in our DAO. An ICO will bootstrap the organization. In time user donations will outweigh the ICO contributions. The donors will inherit the DAO.
