Abstract: In the metaverse, virtual digital assets composed of data need to be unforgeable and accurately traceable, that is, digital assets cannot be copied, and each asset belongs to a unique user. NFT based on public chain endows digital assets with indivisible characteristics to a certain extent, but it can not guarantee the authenticity of digital ownership, so it is not suitable for the establishment of metaverse digital assets. In order to realize the confirmatory right and post-quantum security of digital assets, a digital asset ownership management scheme based on quantum threshold cryptography and quantum teleportation is proposed, which can realize theoretical unconditional security.

Keywords: blockchain; quantum threshold cryptography; metaverse; digital asset; post-quantum security
