Flexible total supply compatible with ERC20 standard ?

[virgile-dev]

Following the discussions during the offsite, I'd like to have a technical validation that we can implement a flexible total supply when using the ERC20 standard.

Here are the links I've been checking that makes think it's possible :

Setting a total supply is a hard constraint. So we definitely need to set one, however what we can do, after we (the owner of the contract) deploy the contract is to mint new tokens, therefore, increasing the total supply. We have to do this manually though every time. Not having a fixed supply could affect thr legitimicy of the system, because it wouldn't be clear for the token holders how the supply will be increased. So maybe we can set some pre defined constraints for us to increase the supply hard coded in the contract: something like e.g. 10% max supply increase per year, etc. What do u guys think?

Yeah, means we to define a monetary policy ahead.
@aecc is minting new tokens is a function we can use or does it mean we need to redeploy the contract ?

We can just use a function to update/increase the total supply, there is no need to redeploy contract
