Gas amount increasing constantly

[hakimehmordadi]

Hello,

In our chain, we are seeing Gas amount is increasing constantly for every transaction.

Is there something to do to make it constant OR at least not increase so much?

Thanks

In what context are you referring to? Specifically, are you saying identical transactions have increasing gas costs?

Hi @alexanderbez
Thank you for answering me.

Actually, In general I want to decrease the gas amount for our transactions but in some cases there is even a difference in gas & fee amount of even identical transactions. But in general I see transactions gas amount is very high, this is a sample for one of our transactions:

gas | 1035024 / 2000000
fee | 0.0005

As you see these amounts are very high for a transaction and sometimes I see for the same transaction even gas amount increases.

My question is: Is there some config for node or validators to be able decrease gas amount or make it constant? Maybe there is a config OR code that I'm missing.

I know reading and writing to the SDK has cost and more reads will increase the gas amount.

But please direct me how I can decrease the gas amount?

Thanks

You can provide a GasConfig in the framework, yes. This will change the values charged, but note, it will never be constant. This is because we charge gas based off of key/values read and written, in addition to things like tx size and sig verification.

Is there a sample for GasConfig to send me the link? I would appreciate.

So this is the default gas config used in the SDK -> https://github.com/cosmos/cosmos-sdk/blob/v0.47.6/store/types/gas.go#L232
