As a Klima co-founder and core team member, I am strongly against this.
The argument for me isn't about the quality of the credits, it's that MCO2 pretty much acts as a Moss token by proxy. Moss is a centralized, VC backed company , they are picking the projects, buying the credits tokenizing them and then selling them. This kind of policy decision enriches them, and other MCO2 token holders, and is again just another middleman, who I thought the whole point of this was to replace?
With BCT, any carbon project can bridge their own tokens and mint Klima or use the BCT to take out a loan and finance themselves. None of this is possible for MCO2 and centralised approaches like this.
On top of all of this, we have fragmentation of liquidity, and competing tokens... again... re-inventing the same this that was always there off chain in the first place.... The whole point of bringing credits on chain is to build an abstraction layer and meta-registry on top of these different credit types, but now we have another abstraction next to an existing abstraction, and we just end up with an even more ugly fragmented, illiquid monster markets than before...
