Gas Pricing Strategy

[AdityaSripal]

Decide on a gas pricing strategy for Ethermint (i.e. how much gas does each operation cost). There are two obvious choices:

1. Use SDK's pricing strategy
2. Use Ethereum's pricing strategy

I think it makes sense to use Ethereum's pricing. We will probably use that anyway for the gas cost of each opcode during a smart contract call, so it makes sense to use it everywhere else as well.

Mind looping me in on the discussion as well? I'd like whatever we implement to be exposed via the usual Web3 RPC methods.

For sure @mslipper

This is our chance to fix Etheruem's gas pricing! This is a known problem with ethereum. I think we should look at all the problems with Ethereum's existing gas pricing and incorporate fixes for them.

Upon further thought, I think we should use Ethereums existing gas pricing, so all existing tooling and contracts "just work", and its not an annoying edge case thats a barrier to adoption. We can make a better pricing scheme after adoption (or make an easy way to alter the pricings)

@ValarDragon yes, would love as much as your input as possible. But you hit the nail on the head:

Upon further thought, I think we should use Ethereums existing gas pricing, so all existing tooling and contracts "just work".

This is our ultimate aim at release.
