I hate the great idea that pops up right before bedtime. You need to validate or kill it to find sleep.

After a year in a half leading the tech validation effort at IO, I thought it would be nice to take a step back and look at what we achieved so far. Here is a short recap.

🧵 From ideas to implementation: how Input | Output’s R&D team is shaping the future of Cardano 👇. As blockchain becomes core infrastructure, rigorous R&D is vital. At Input | Output (IO), research isn’t just theory – it powers real-world systems like Cardano.

If you have some interest in Cardano’s future, watch it. I can’t praise enough the effort of the team to build a strong proposal and to explain its value.

And yes, we didn't disclose the date earlier. Sorry for that, but there was already enough pressure on the team, and thing could have gone south (there's always a minor chance that great ideas can't face the hard truth of reality).

The "secret roadmap" was to have a PR by end of August. We didn't want to disclose it because there was high uncertainty, as with any R&D work. And we faced challenges. Yet, here we are, with the integration of feedback on failed transaction, and a more minimal impact on dApps.

Covered in the monthly:.- The detailed description of the proposed variant of Leios. - The implementation material (formal specification, mini protocols description). - Tradeoffs and problem space. - Potential (positive) impact on script budget. - Resistance to attacks.

So, here it is, we know have a public and submitted CIP for Leios. More than ever, it's now time for feedback. It may be too early to celebrate, as we want to be sure that the community agrees on it first, but it's a huge milestone.
