# What is ChainDB Density?

The number in

``````cardano_node_ChainDB_metrics_density_real 4.859720566067451e-2
``````

that also shows up here …

merci

If I’m not mistaken, I believe chain density represents the amount of active nodes in the ecosystem that are running a supported version of the Cardano software. The higher the number, the healthier the network.

The current block coefficient is 0.05 (i.e. 5%), so we currently have …

`60 x 60 x 24 x 5 => 432000 slots/epoch`

and …

`432000 x 0.05 => 21600 blocks/epoch`

The density measures the actual block production rate.

`4.872 / 5.0 => 97.44%`

of blocks are actually produced.

It follows, that density is an overall network metric and not so much a metric of how well your particular node performs.
