MarsChain is an EVM-compatible public chain with one entry rule: participation starts with a burn. There is no mining rig to buy and no stake to unlock later. A user destroys MARS, the protocol records a lasting share of network weight, and that share decides how new tokens are divided.Three mechanisms do the work. Proof of Contribution decides what counts. The 188-day cycle prices a burn against a still-network reference, then moves the scale as conditions change. The hashrate layer turns that weight into rewards, inside a hard cap of 200 billion MARS and a halving every 448 days.The 188-day number is a design reference, not a payout promise. It describes how the rules try to stay consistent. It does not describe what any wallet is guaranteed to receive. Proof of ContributionOn most chains, influence comes from hardware or from coins that remain in a wallet. On @MarsChainDAO ,influence comes from coins that leave.Holding MARS creates no mining weight. Sending MARS to a black-hole address does. The tokens are gone from circulation, and the protocol writes down a matching Contribution Rate for the address that burned them. That rate is the network’s hashrate: a permanent claim on a fraction of future block rewards, set by the size of the burn and by the conversion rate in force at that moment.The burn is public and can be checked on the explorer, so contribution is a recorded state change rather than an off-chain claim. The weight does not expire after a lockup. It stays on the books and is used whenever rewards are split.The contrast with older models is direct. Proof of Work spends electricity to manufacture hashes. Proof of Stake usually pays people for holding or locking tokens. Proof of Contribution deletes tokens and, in the same step, records a lasting production share. Scarcity and participation are not two policies. They are one action. The cycle answers a pricing question. If the network froze, how much weight should a burn receive so that, on paper, it could earn back a similar number of tokens in about 188 days?Frozen is the key word. The reference assumes total hashrate and daily output barely move. Under that picture, the protocol sizes the conversion so a burn’s expected coin output over 188 days lines up with the amount destroyed. A sample often used to show the rule puts the network at 10,000P of hashrate and daily output near 223 million MARS. In that snapshot, burning 1,000 MARS maps to about 23.8P, and 188 days of rewards come out near 1,000 MARS. It is a worked example of the pricing logic, not a prediction of what a live network will pay. Live networks do not freeze. Every new burn lifts total hashrate, so each existing unit earns a thinner slice. Daily output also steps down on the halving calendar. Leave the conversion rate fixed, and a burn today and a burn much later would be playing different games.Calibration is the correction. As total hashrate rises against a reference point, the protocol changes how much weight a new burn receives. The aim is to keep the theoretical coin-based window near 188 days while the network expands and issuance shrinks. The scale moves with the network. It does not lock in a personal return. What actually arrives still depends on how fast hashrate grows, how far emission has fallen, and what the token is worth. Mining here is burn-to-mine. Destroy MARS, receive hashrate, and collect a share of block rewards equal to your share of the network total. No GPUs, no ASICs, no hardware bills, and no deposit waiting to be returned. The tokens are spent. The weight remains.That hashrate is not computational power. It is a score the protocol assigns. Individual scores add up to a network total, and rewards are cut by each score’s fraction of it. Published materials put about 75 percent of output with hashrate holders and about 25 percent with validator nodes.The total does two jobs. It is the base for splitting rewards, and it is the signal that reprices the next burn. A new participant does not only collect their own weight. They also change the scale everyone else is measured against. An address that never burns again can watch its relative share fall as others add hashrate.Issuance is boxed in twice. Supply cannot pass 200 billion. Output halves every 448 days, so the pool of new tokens gets smaller on a fixed clock. Later cycles pay less for the same weight unless calibration grants more weight per burn to keep the 188-day reference in sight. Keeping a share of rewards means keeping pace with hashrate growth, not sitting on an old balance.Two side valves sit next to ordinary mining. The Christmas Protocol opens on a yearly schedule. The Oracle Protocol can open if price stays about 50 percent below its all-time high for seven days. Each runs for about eight days and pairs supply burns with hashrate expansion. Neither replaces Proof of Contribution. They are pressure releases when the calendar or the market leaves ordinary conditions. Proof of Contribution decides who has weight: only a burn creates it. The 188-day cycle decides how that burn is priced, first against a still network, then through recalibration as totals and issuance change. The mining layer spends that weight on block rewards, while the 448-day halving limits how many new tokens exist to share.A single burn therefore cuts circulating supply, adds lasting hashrate, and shifts the terms for the next burn. That loop is the design. It is not a yield product. The 188-day window, the reward split, and the halving interval are rules meant to keep the system internally consistent. What any participant actually receives still depends on network growth, emission, and price.
