In Cosmos, a minimum gas prices are determined by the validators of the network, and each validator can specify a different minimum value for their fees.
This potentially allows end users to submit 0 fee transactions if there is at least one single validator that is willing to include transactions with 0 gas price in their blocks proposed.

- Using the default configuration.
- Changes will be globally set by vote.
- Eventually nodeholders will be allowed to set their own gas fees.
Open for discussion.
