[chain] Gas Fee Equation

[zivkovicmilos]

Description

This effort covers the introduction of a standard gas formula for VM transaction executions.

The majority of this effort is covered in a detailed issue on the Gno repo already.

Having a standard gas fee equation enables estimating transactions, and having deterministic gas usage across gno nodes and transactions.

Successful outcome of this effort:

• A gas fee equation is defined and implemented for transaction parsing

Moving this issue out of the Mainnet launch milestone, since we have #1917 in the mainnet launch scope.
