You can do research on what Ocean does if you are not aware by using above links. But it is currently one of the most established projects with corporate backing, Germany based I believe.
Interestingly, other such major platforms choose to stay on their native blockchain. But Ocean likes to be deployed on several Layer-1 protocols. Not only Ethereum. You can even apply for fundng and they support their deployment.
A new project without having to develop new things, just deploy. A Quick Win for Tezos Developers and Tezos community?
Interested in your opinion.
