Launched on 16/01/2021, Cometh is an innovative strategy game that allows players to win valuable tokens and utilizes the Decentralized Finance ecosystem to establish a sustainable and enduring outer space. Cometh incorporates all the fundamental features of the Ethereum blockchain and also integrates an Optimistic Rollup layer 2 scaling solution.

In Cometh, players control spaceships (referred to as astrominers) orbiting around massive stars with the objective of positioning themselves near passing asteroids (known as smart asteroids). When in close proximity, players can mine tokens from these asteroids. To enhance their positioning, spaceships can be attracted towards other spaceships by paying a fee. Players can also manipulate the fee they charge and leverage their strategic position in outer space.

Smart asteroids are smart contracts that represent asteroids in the game. Adhering to Kepler's 1st law, smart asteroids follow an elliptical trajectory around the star. The parameters of a smart asteroid's trajectory are randomly determined from the block hash in which the asteroid appears.

The creation of new smart asteroids is a decentralized process managed by the Cometh Generator. The Cometh Generator is a smart contract that can accumulate various Ethereum-based assets, including ERC20 tokens and Ether. Once a certain threshold of tokens is reached, anyone can trigger the deployment of a new smart asteroid by calling the Cometh Generator. The accumulation of valuable tokens on the Cometh Generator leverages the Decentralized Finance ecosystem to ensure a sustainable rhythm of new smart asteroid deployments.

Spaceships in Cometh are vessels designed for mining smart asteroids. On the blockchain, spaceships are represented as Non-Fungible Tokens (NFTs) based on the ERC721 and ERC1155 standards. Spaceships follow a circular trajectory around the sun, with their initial parameters randomly determined from the block hash of their creation. Spaceships can be pulled towards other spaceships in space to approach a smart asteroid. Additionally, spaceships can be upgraded with other NFTs such as improved drilling tools, engines, or crew members, which affect their abilities in the game.

The MUST is the ERC20 token that drives Cometh's economy. When at rest, the MUST allows players to earn new game assets. The pulling service of a spaceship has a price expressed in MUST, determined by the spaceship's owner. By default, all spaceships start with a pull service price of 0.001 MUST. When acquiring a spaceship from the Cometh protocol, the owner receives a portion of the spaceship's price in MUST to kickstart their activity in the game. The MUST has a limited supply of 1,000,000 units and serves as a commodity in Cometh. To store and utilize the players' MUST, the Cometh protocol employs a smart contract called the TUBE.

The TUBE smart contract facilitates several in-game mechanisms, including NFT Farming, where MUST stored in the TUBE allows players to unlock perks, upgrades, and rare spaceships that can be freely used or transferred. Moreover, MUST tokens locked over time in the TUBE generate DUST counters that players can redeem for new NFTs.
