This week I did not work on my usual stuff because I went to Istanbul to attend Cosmoverse 2023, the biggest event for Cosmos ecosystem. It was an amazing experience where I met a lot of interesting projects and people to connect with.
In the end of the week I also attended Hackmos: the hackathon tied to the Cosmos ecosystem. I joined a team mostly made by Evmos employees and we worked on the ABCI++ track.
ABCI++ (Application Blockchain Interface) is the new interface between CometBFT, the concrete consensus protocol of Cosmos chains, and the blockchain itself. In particular ABCI++ gives developers more power over the block production since it adds extra steps of communication between CometBFT and the validators of the chain that can inject arbitrary custom logic.
We developed abcAI++ moderator: a project that automatically filters out scam proposal that are made on Cosmos governance forums.
Nowadays scam proposal, containing fishing links or fake airdrops announcements, are very often published on Cosmos governance forums and they have to be manually removed.
Using ABCI++ we were able to add custom logic during the block production that automatically detects when a new proposal transaction is published, it sends it to OpenAI that assigns it a score. On the next block if the aggregate score (an average) is higher than a certain threshold, the governance proposal is automatically deleted.

In the end we won the first price for our track. Here is a us immediately after the proclamation.
