The supply figure, and what it actually means
Dogecoin has no maximum supply. Each block awards a fixed 10,000 DOGE, blocks arrive roughly every minute, and that continues indefinitely. Around 5.2 billion new DOGE are issued each year, forever.
This produces a specific economic property worth understanding: the absolute issuance is constant, so the percentage inflation falls every year as the base grows. It is not deflationary like Bitcoin and it is not accelerating either — it is a fixed nominal drip against a growing denominator.
The figure Dogechain.info reports is coins issued, derived from block height. That is a genuine on-chain measure. It is not the same as coins in circulation in any economic sense — it includes coins in wallets whose keys were lost years ago, of which Dogecoin has a great many given its history.
We are pointing this out because the number gets quoted as though it means something more precise than it does. Issued supply is an exact, verifiable fact. Circulating supply is an estimate that requires assumptions nobody publishes.
Merge mining with Litecoin
Since 2014 Dogecoin has been merge mined with Litecoin. Both use Scrypt, and miners can submit the same work to both chains simultaneously, earning on both for one unit of effort.
This was an elegant solution to a real problem. Dogecoin's own hash rate was low enough that a determined attacker could have rented enough capacity to attack it. Merge mining meant it inherited the security of Litecoin's much larger mining ecosystem at no cost to either.
It also means Dogecoin's security is not independent. A collapse in Litecoin mining economics would affect Dogecoin directly. That is a structural fact rather than a criticism, and it is rarely mentioned in discussions of either chain.
Dogechain.info shows difficulty and hash rate, though it does not surface the merge-mining relationship. BitInfoCharts is better for comparing the two chains side by side over time.
Practical use
Dogecoin is a UTXO chain, structurally almost identical to Bitcoin with faster blocks and different parameters. Everything in our guide on reading a Bitcoin transaction applies directly — including the change-output confusion that makes the "amount sent" look far larger than the payment.
Fees are low and blocks arrive every minute, so stuck transactions are rare. When one does stick it is nearly always because the fee was set below the relay minimum. Dogechain.info has no fee visualisation to help diagnose that, which is where a modern explorer would.
Confirmation requirements are worth noting. One-minute blocks mean each confirmation represents considerably less accumulated work than a Bitcoin confirmation, which is why exchanges typically require far more of them for Dogecoin deposits. Their threshold governs when you are credited, not the explorer's display.
Where a modern explorer does better
Blockchair indexes Dogecoin with the same query layer it applies to Bitcoin, which means filtering, sorting and aggregation that Dogechain.info cannot approach — and a keyless API with permissive CORS.
BlockCypher covers Dogecoin with webhooks and transaction construction, which is the right choice if you are building something that needs to react to incoming payments.
3xpl is faster for a plain lookup and works without JavaScript.
Dogechain.info survives mainly on familiarity and on being the supply figure people cite. Both are real reasons for it to exist, and neither is a reason to use it for anything else.
What our reference tests showed
We tested Dogechain.info against the two things people actually use it for, and against a modern alternative on the same data.
The supply figure reconciled. We computed expected issuance independently from the block height and the fixed 10,000 DOGE block reward, accounting for the early variable-reward period, and the explorer's figure matched. That is worth confirming rather than assuming, given how widely the number is republished.
Address and transaction lookups were correct. Balances matched Blockchair on every address we tried. The transaction pages showed inputs, outputs and fees accurately, including the change output that makes total output look far larger than the amount paid.
Where it fell behind was everything else. Our deliberately-underpaid transaction test showed only "unconfirmed" with no fee-rate context and no indication of what rate was currently clearing. On Bitcoin that gap matters enormously; on Dogecoin, where the mempool is usually near empty and the transaction confirmed within a few minutes anyway, it mattered considerably less. The limitation is real and its practical consequence on this particular chain is small.
The JSON endpoints worked without a key, which we verified from a clean request. They are simple to the point of austere — a balance endpoint returns a balance — and for a script that is a virtue.
Running the same lookups through Blockchair returned the same numbers with considerably more context, a query layer, and the same absence of an API key requirement. That comparison is the honest summary of where this explorer now sits.
