At the dawn of the 25th Century, faster-than-light travel allowed mankind to spread across the universe.
The discovery of the resource-rich Omega Galaxy became the focus of human expansion.
A thriving new civilisation flourished among the stars, as outposts and stations grew and prospered.
Until an ancient destructive force was awakened...

The Game

Doomsday: Survivors of the BLast is a fully on-chain game, built with scarcity, and boom-bust cycles at its core. Stations must be mined during the Expansion, and then compete to survive Blasts the Wasting to win an ETH prize pot.

Stations

Every Station is an ERC-721 compliant NFT on the Blast L2. Stations are located on the Galactic Map, and each has a unique artwork generated from the tokens hash, with a uniqe name. Stations must be minted by mining during the Expansion, and then reinforced during the Wasting in order to survive. The mint cost is dynamic, and is based on the current supply of Stations, as all Stations earn ETH when a new Station is minted. This ETH can only be claimed by Abandoning the Station (burning the token) and removing it from the game.
The mint cost starts at 0.02 ETH, with the majority of the mint fee being added to the prize pool. It remains at this level until there has been sufficient Station growth, at which point it begins to increase.

Mineable NFTs

Check out the [ settings ] button on the miner for additional settings that can help with mining, including enabling an alarm which will alert you when the miner finds a Location.
Doomsday: Survivors of the Blast uses Proof of Work mining for creating new tokens. It creates natural token scarcity without significant network usage.
The mining process is used to find a Location where a Station can be founded. When a Station is founded its properties are generated using the output of the mining process called a hash – this means that every Station is visually unique, with some properties being more rare according to an improved scarcity model. The Station's Primary Industry, which determines how quickly it earns ETH, is also derived from the hash.

Mining

Mining can be done using only your browser. The Miner will look for a Location for a new Station, and when it finds one, you will be able to submit a transaction to Found your new Station.
Players can mint up to 20 Stations at once when a Location is found. You can choose how many Stations you want to mint in [ settings ]. This number can be changed while mining, or after a Location is found.
The mining algorithm includes your wallet address in its calculations, meaning any location that it finds is unique to your wallet, and can not be front-run by another player.
For more information on how it works, read the Whitepaper.

The Awakening

As humanity spreads across the Omega Galaxy, the Rectifier watches and waits. It lurks in the dark until civilisation has reached its peak, and then Awakens and The Wasting begins.
During the Expansion, a timer counts down until the Awakening. Every time a new Station is founded the timer is extended a little, but the maximum that the countdown can be is 24 hours.
At the same time, due to the increasing mining difficulty, the average time to mine a new Station increases. This narrowing window means the number of people competing to mint Station must increase or the Rectifier will Awaken.

Blasts

During the Wasting, Blasts will occur every 240 blocks (approx. 8 mins). The location and radius of these Blasts is determined on-chain, using rolling, retroactive blockhashes as a source of randomness. Blasts that hit Stations can be confirmed by anybody, and 0.00001 ETH is set aside to pay the gas fees of this transaction. If a Station is vulnerable (inside the Blast radius on the Galactic map), a "Confirm Blast" button will be visible on it's Station's info page, and on the game's action bar.
Any Station that has a Blast pending confirmation can not be sold, Abandoned or Reinforced.
Note: Station locations and Blasts are both derived from their respective hashes, calculated and stored on-chain.

ETH Prize

The final surviving Station at the end of a Wasting will win an ETH prize pot, from both mint fees and reinforcement fees.

Reinforcement

Any surviving Station can be reinforced by its owner. There are four types of Reinforcement, each protects against one type of Blast.
Ion Paneling protects against Ion Blasts.
Plasma Shields protect against Plasma Blasts.
Charging Arrays protect against Dark Matter Blasts.
Faraday Meshes protect against Radiation Blasts.
Each time a Station receives extra reinforcements, it can survive an extra Disaster of the associated type, but reinforcement costs double each time for any given type for any given Station.

Abandon

Any surviving Station can be Abandoned by its owner. The Station will be destroyed, and the owner will receive the ETH it earned during the Expansion, and a portion of the Prize Pool if it is during The Wasting. As more Stations are destroyed, this should raise the floor price for those that remain, as they're essentially backed by a fraction of the prize pool.

Confirm Blasts

During The Wasting, anybody can confirm Blasts that have affected Stations. 0.00001 ETH is paid to anyone who confirms a Blast, which will cover any gas costs incurred.
For the first 60 blocks (approx. 2 mins), only the owner of a vulnerable Station can confirm its Blast.
For the next 60 blocks, the game creators have priority. This was added in response to the confirmation process being heavily controlled by bots.
For the next 60 blocks, anyone who owns a Station can confirm a Blast.
In the final 60 blocks, everyone can confirm Blasts.

Alliances

Players have the ability to create and join Alliances. Each Alliance has its own contract, and site. You can view and create Alliances at the Doomsday Diplomacy Hub.
