|
|
|
* every block
|
|
* based on the last 720 blocks, excluding 20% of the timestamp outliers
|
|
|
|
## Block time
|
|
|
|
* 2 minutes
|
|
* may change in the future as long as emission curve is preserved
|
|
|
|
## Block reward
|
|
|
|
* ~6 XMR as of Dec 2017, see the [latest block](https://moneroblocks.info/) coinbase transaction amount for current reward
|
|
* smoothly decreasing and subject to penalties for blocks greater then median size of the last 100 blocks (M100)
|
|
|
|
## Block size

|
|
|
|
## Emission curve
|
|
|
|
**Main emission**
|
|
|
|
First, the main emission is about to produce ~18.132 million coins by the end of May 2022.
|
|
|
|
As of Dec 2017 the emission is about 30 XMR per 10 minutes.
|
|
|
|
See [charts and details](https://www.reddit.com/r/Monero/comments/512kwh/useful_for_learning_about_monero_coin_emission/).
|
|
|
|
**Tail emission**
|
|
|
|
The tail emission kicks in once main emission is done.
|
|
|
|
It will produce 0.6 XMR per 2-minute block.
|
|
|
|
This translates to <1% inflation decreasing over time.
