Adoption is a problem for the blockchain industry and the lack of dApps that are useful in solving/facilitating society’s current challenges contribute for it. 
Despite its 15 years, blockchain didn’t really prove its value in domains other than DeFi.
Cartesi’s unique vision and contribution
Cartesi, with its unique design for a execution layer based on a VM running a Linux operational system, can contribute providing a robust development environment, full of well known development tools, that can allow researchers and developers to explore much more efficiently all these unexplored domains (other than DeFi) what would be very hard, or even impossible, to be done with other existing solutions.
Imagine what can come when hundred/thousand of developers start hacking, exploring and experimenting taking benefit of the expanded design space that Cartesi provides… This seems to be a promising path for Cartesi and the project will need to continue investing on internal experimentation and also promoting public hackathons to create this huge community of developers, but may probably take time until useful dApps come.
Adapting the vision to the current reality
The present topic brings a proposal for Cartesi to also invest, in parallel, in the DeFi vertical to bring potentially awareness and visibility more quickly, because this is a more consolidated domain for blockchain.
This seems to be the adoption strategy that other projects are tacking. For example, EigenDA when announcing its launch partner program wrote on X :
To kick things off we’ve written a case study on @LayerN_Official and how it uses EigenDA to superpower its rollups for DeFi.
Another example comes from Starknet foundation that recently announced a huge investment “across multiple initiatives to drive the adoption and growth of the Starknet blockchain”, but one specific for DeFi. 
3/ On-Chain Incentives for DeFi
We’ve allocated an initial 50M STRK to explore the direct, indirect and retroactive incentivisation of activity on DeFi protocols by boosting liquidity, volume traded and general growth of the DeFi landscape on Starknet.
Bringing this to Cartesi, maybe dApps like DCA.Monster (see also this discussion on Discord) can have a more effective impact as the second Cartesi dApp on mainnet than other in not well established domains. To make this possible, the roadmap should also prioritize features to support effective experimentation/development on the DeFi vertical.
