SECTOR is a backup virtual token of the blockchain (using the ERC-721 standard for NFT) that represents the minimum unit of the physical space package of the TRC Metaverse. The player can own part of the TRC Metaverse via SECTOR and host content (ASSET and GAMES) to the SECTOR he owns or leases.

The physical space of the replica metaverse is based on a map of the Universe MAP with infinite SECTORs. PLANET is a collection of physical spaces of SECTORs within Metaverse owned by players to create and monetize content, and forms huge governance. SECTOR is used to publish content and can also be loaned to content creators. All SECTORs come with a prebuilt terrain set, but the terrain can be customized at a cost by the players who own it (or other players who invite it to work with it). However, the unique elements of SECTOR, such as air, minerals, materials, and restrictions, cannot be changed.

In the future, players will be able to combine the SECTORs to form a DISTRICT. In the future, a small number of players may own multiple DISTRICTs or PLANETs. In the event of a war agreed upon by both parties by the governance of each PLANET or the combined PLANET governance, ownership of the SECTOR and its ASSETs and content may be transferred to the winner, depending on the conditions. All of these degrees of freedom are determined by the major decisions of great governance. The TRC supports an absolute peace in the ecosystem, but prioritizes the players and the will of each governance.
