Why did a Dogecoin block just take 5 minutes?

Block discovery is a Poisson process: every hash is an independent lottery ticket, so the gaps between blocks follow an exponential distribution around the 1-minute average. About 0.7% of gaps run longer than 5 minutes — roughly ten per day at 1,440 blocks a day — and they are normal variance, not a network problem.

How many Dogecoin blocks are mined per day?

1,440 on average — 86,400 seconds per day divided by the 60-second block target. Each block pays a fixed 10,000 DOGE subsidy forever, so daily issuance is about 14.4 million DOGE (~5.26 billion per year); the inflation rate falls each year as total supply grows.

What is merged mining (AuxPoW)?

Dogecoin accepts Litecoin's scrypt proof-of-work via AuxPoW, so most Litecoin pools mine both chains at once with the same hardware and no extra energy. That is why Dogecoin's hashrate closely tracks Litecoin's, and why DOGE rewards are a meaningful bonus for scrypt miners.

What is a block?

A block is a batch of transactions bundled under a small header that commits to the previous block's hash, a merkle root of the transactions, a timestamp and a nonce. Dogecoin targets a new block every 60 seconds — ten times Bitcoin's pace — and each one pays the miner a fixed 10,000 DOGE subsidy plus fees, forever. There is no halving: the amount of new DOGE per year stays roughly constant (~5.26 billion), so the inflation rate falls every year as total supply grows.

Why block intervals are random

Hashing is memoryless: every hash attempt is an independent lottery ticket, and past effort builds no progress toward the next block. Block arrivals therefore form a Poisson process, and the gaps between them follow an exponential distribution — the expected interval is 1 minute, but the actual intervals in the table scatter from seconds to several minutes. That spread is the system working as designed.

P(no block for t minutes) = e^(−t / 1)
P(gap ≥ 5 min) = e^(−5) ≈ 0.7% of gaps → roughly 10 per day at 1,440 blocks/day
average blocks per day = 86,400 s ÷ 60 s target = 1,440

From block pace to the difficulty adjustment

Unlike Bitcoin's fortnightly retarget, Dogecoin uses DigiShield: difficulty is recalculated every single block, comparing recent block times against the 60-second target with smoothing and damping so one lucky or unlucky block only nudges it. That lets difficulty track Litecoin's big merge-mined hashrate swings within minutes instead of days.

DigiShield: retarget every block (not every N blocks)
next_difficulty ≈ current_difficulty × (60 s target ÷ smoothed_recent_block_time), damped

Merged mining with Litecoin

Since 2014 Dogecoin has accepted Litecoin's scrypt proof-of-work through AuxPoW (auxiliary proof-of-work): a Litecoin miner embeds a commitment to a Dogecoin block in its work, and a solution good enough for Dogecoin's target counts on the Dogecoin chain — same hardware, same electricity, two coins. Most large Litecoin pools do this by default, which is why Dogecoin's hashrate closely tracks Litecoin's and why DOGE rewards are a meaningful part of scrypt mining revenue.

For a scrypt miner, the 10,000 DOGE per block is effectively a bonus on top of LTC rewards. The calculator prices it per MH/s at the live network hashrate.
