Dogecoin Tokenomics: Uncapped, Constant Issuance
Abstract
Dogecoin is a proof-of-work memecoin whose issuance rule differs from Bitcoin's in one essential way: after its early reward eras it pays a constant 10,000 coins per block indefinitely. Supply is therefore unbounded but perfectly predictable, and the annual inflation rate declines as the supply grows. We derive the rate, tabulate it for illustrative supply levels and explain merged mining with Litecoin.
Keywords: Dogecoin, constant issuance, no supply cap, Scrypt, merged mining, memecoin
1. Issuance rule
Dogecoin Core describes the coin as a community-driven cryptocurrency inspired by a meme and states that it uses the Scrypt hashing method for proof of work [1]. Its subsidy function shows the schedule: in earlier eras the reward was derived from the previous block hash or halved on a schedule, and from six halving intervals onward, block 600,000, the subsidy is a constant 10,000 coins per block [2]. The target block spacing is 60 seconds [3].
Table 1. Dogecoin issuance arithmetic after block 600,000.
| Quantity | Value | How derived |
|---|---|---|
| Blocks per day | 1,440 | 60-second target spacing |
| Coins per day | 14,400,000 | 1,440 x 10,000 |
| Coins per year | about 5.26 billion | 525,600 blocks x 10,000 |
2. Inflation as a percentage
Annual issuance divided by circulating supply gives the inflation rate. Since issuance is constant, the rate falls as supply grows. The supply figures below are illustrative inputs, not current statistics; substitute the live supply to get today's rate.
Table 2. Annual inflation for illustrative supply levels.
| Circulating supply | Annual issuance | Inflation rate |
|---|---|---|
| 100 billion | 5.26 billion | 5.26% |
| 150 billion | 5.26 billion | 3.50% |
| 200 billion | 5.26 billion | 2.63% |
annual inflation rate = 5,256,000,000 / circulating supply
The supply grows without bound, but the growth rate asymptotically approaches zero. That is the same asymptotic behaviour as a fixed cap in percentage terms, reached through a different route: Bitcoin's curve flattens because issuance stops; Dogecoin's flattens because the base grows.
3. Why constant issuance
Constant issuance gives miners a permanent, predictable subsidy, so security does not depend entirely on transaction fees. The cost is dilution: holders bear a continuing, though shrinking, inflation. Monero later adopted a comparable idea, a permanent tail emission of 0.6 coins per block after its main emission ended [4]. Dogecoin and Monero show that a proof-of-work chain is not required to have a cap; what makes its supply rigid is that the schedule is fixed in consensus rules.
4. Shared security with Litecoin
Dogecoin activated auxiliary proof of work at block 371,337 and assigned itself an auxiliary chain identifier [3]. With merged mining a Scrypt miner can submit one proof of work to both Litecoin and Dogecoin [5]. The two assets therefore share hash power while keeping different supply policies: a capped one and an uncapped one.
5. A supply-and-demand reading
Dogecoin's supply side is completely specified: no mint authority, no administrator, no discretionary change to the schedule short of a network-wide fork. Its demand side is cultural and transactional: tipping, payments and community identity. Evaluating it as a memecoin means noticing that demand, not supply, is the variable; the supply is boring by design.

Common questions
Does Dogecoin have a maximum supply?
No. Dogecoin Core's subsidy function pays a constant 10,000 DOGE per block once the chain passes block 600,000, with no cap in the code.
Is Dogecoin inflationary?
In absolute terms it issues about 5.26 billion coins a year, but the percentage rate falls as the total supply grows.
