Block rewards and emission

How new QRL is created through mining rewards, and why the emission schedule decays over time.

New QRL doesn't appear from nowhere — on QRL Legacy it's created as block rewards paid to miners. This guide explains how that issuance works and why it slows down over time.

The coinbase: minting new coins

Every block a miner produces includes a special transaction called the coinbase. Unlike an ordinary transfer, it has no sender — it simply creates new QRL and pays it to the miner as a reward for the work of producing the block.

The coinbase is the only way new coins enter circulation under Proof-of-Work. It's also the incentive that keeps miners participating: solve the puzzle, add the block, collect freshly minted QRL plus the fees from the transactions you included.

Decaying emission

QRL Legacy doesn't pay a flat reward forever. It uses a decaying emission schedule: rewards start higher and shrink over time, so the total supply rises quickly at first and then ever more slowly as it approaches the 105 million cap.

The logic behind a decaying schedule is familiar from many chains:

  • Front-load incentives when the network is young and most needs miners, and
  • Taper inflation as the chain matures, protecting long-term holders from endless dilution.

The exact curve has been adjusted by community governance over QRL's history, but the shape — high early, declining toward the cap — is the constant.

Genesis isn't a block reward

A subtle but important point for reading supply data: QRL's genesis allocation (~65 million, from the 2018 token migration) is not a mining reward. It's the chain's starting balance, recorded at block zero. Only the emission after genesis comes from coinbase rewards. Conflating the two would make the supply look far larger than it is — which is exactly why this explorer counts genesis separately from the mining timeline.

QRL 2.0: rewards without mining

QRL 2.0 has no coinbase mining reward. Being Proof-of-Stake, it pays validators through staking rewards delivered as withdrawals. The principle — new issuance as a reward for securing the chain — is the same; the mechanism is entirely different.

FAQ about Block rewards and emission

Common questions about this page
What is a block reward?
A block reward is newly created QRL paid to whoever produced a block — a miner on QRL Legacy. It's delivered through a special 'coinbase' transaction and is how new coins enter circulation under Proof-of-Work.
Why does QRL's emission decrease over time?
QRL Legacy uses a decaying emission schedule: block rewards start higher and shrink over time, so supply approaches the 105 million cap gradually rather than all at once. This front-loads incentives for early miners while controlling long-term inflation.
Does QRL 2.0 have block rewards?
Not in the mining sense. QRL 2.0 is Proof-of-Stake, so validators earn staking rewards paid as withdrawals, rather than a mined block reward delivered via a coinbase transaction.
