I've noticed a very interesting development in Ethereum lately. The developers are seriously working on a cryptographic analysis of Poseidon2, and they've discovered some security issues that need to be addressed.

Instead of simply committing to a single version and making a fixed precompile, which could introduce unnecessary complexity and consensus risks, Ethereum is taking a smarter approach. They are developing a flexible precompile that can perform vector mathematics operations with 32-bit numbers. This changes the game in terms of efficiency, significantly reducing gas costs.

The cool thing is that this approach opens doors to various applications. You can implement different versions of Poseidon without being locked into a single choice. And there's more: this will greatly boost operations with quantum-resistant signatures and fully homomorphic encryption. Basically, it's like giving the EVM a GPU.

For now, they are exploring this solution with quantum numbers in mind, thinking about how to protect the protocol against future threats. The idea is to maintain flexibility while solving the security issues that arose with Poseidon2. I found this move very strategic.
