What a transaction actually costs on QRL, by percentile, as one continuous timeline from the original Proof-of-Work chain into QRL 2.0. The median (p50) is the typical fee; p95 and p99 show what busy-day peaks look like. Only fee-paying transactions count, so coinbase rewards don't drag the median to zero. Shown in Quanta on a logarithmic axis, because fees span several orders of magnitude.

FAQ about this chart

What does the QRL fee percentiles chart show?
It shows what a single transaction cost each day, at three points in the distribution: the median (p50), the 95th percentile (p95) and the 99th percentile (p99). The chart is one continuous timeline running from the original Proof-of-Work chain into QRL 2.0, with a marker at the migration. Reading the three lines together shows both the typical cost and how expensive the busiest transactions got, in Quanta on a logarithmic axis.
What do p50, p95 and p99 mean?
They are percentiles of that day's transaction fees. p50 is the median — half of transactions paid less and half paid more, so it is the typical cost. p95 means only 5% of transactions paid more than that figure, and p99 means only 1% did. The gap between p50 and p99 shows how much pricier the tail of busy, complex transactions was compared with an ordinary one.
Why use percentiles instead of the average fee?
Because a single large or complex transaction — a contract deployment, say — can pay a fee many times the norm and drag the average up, making an ordinary day look expensive. Those heavy transactions show up in the high-gas bands of the daily gas distribution. The median and percentiles describe the actual distribution instead, so p50 reflects what a real user pays while p95 and p99 isolate the outliers rather than letting them distort the headline number.
Does this include fees from the Proof-of-Work era?
Yes — the timeline starts with the Proof-of-Work chain. Its fees are the flat per-transaction fee paid to miners, and only fee-paying transactions are counted, so the fee-free coinbase block-rewards that make up most Proof-of-Work blocks don't pull the median down to zero. After the migration marker the line continues with QRL 2.0, where the fee is the EIP-1559 base fee plus the validator tip. Both halves are shown in Quanta so they share one axis.
Why is the axis logarithmic, and why are the numbers so small?
Fees span several orders of magnitude — a typical transaction, a busy-day p99 and the rare expensive outlier can differ a thousand-fold — so a logarithmic axis is the only way to keep all three percentile lines readable at once; on a linear axis the outliers would flatten everything else to the baseline. The figures are small because they are in Quanta and base fees currently sit at the protocol's floor, far below one whole coin. Expect them to climb toward fractions of a Quanta as real demand grows.
Is this the same as the fee burned chart?
No. This chart shows the total fee a sender paid per transaction, by percentile — base fee plus the validator tip. The fee burned chart shows only the base-fee portion that EIP-1559 permanently destroys, summed per day. So fees here are always at or above the burned amount: the difference is the tip that rewards the block proposer.
