Odaily News Ethereum co-founder Vitalik Buterin posted on social media that "the cryptoeconomic experiment Orb Land is really cool." Orb Land is a cryptoeconomic experiment launched by Eric Wall, the founder of Taproot Wizards, which aims to tokenize personal consulting services into NFTs. Holders who purchase Orb will gain the right to ask questions to the creator of Orb and resell this right. Technically speaking, Orb is an improved ERC-721 that supports the ERC-721 interface, and all transfer-related functions are restored. Although Orb can be displayed on OpenSea, it cannot be listed for sale on NFT trading markets such as OpenSea, Sudoswap or Blur. In addition, Orb manages ownership functions through auctions and the Harberger tax system.
