To keep up with the multiple initiatives shared during our first Node Diversity Workshop in Paris, I would like to propose an online Show & Tell session where anyone interested will have the opportunity to share what they’ve been working on: News, code, documentation, anything relevant to node implementors is welcome.
When?
This session is scheduled on Tuesday, 20th of May, 2025, at 2:30pm Paris time (GMT+2) and will be hosted on the Cardano Scaling group Discord .
How?
The meeting will last at most 1.5 hours, but the exact duration will depend on how packed the schedule is, which itself depends on you:
- You want to show something? Simply post a reply to this message with a title, description, and duration (please keep it short and sweet in order to leave enough room for everyone to present what they have, 5’ seems like a good timing),
- You just want to listen? That’s also fine, just drop by and enjoy,
- You want to do something else? Reply with a suggestion for an activity you want to happen during this session
Save the date in your calendar!

Thanks so much for organizing this Arnaud! This is a great first step.
I’d like to propose we discuss the topic of this thread: Managing a Shared Ledger: New CIP-Like Process? - #7 by JSHyCS
Title: Managing a Shared Ledger (Initial Planning)
Description: Discuss whether or not we need to define a new process for upgrading a shared ledger. If we do, let’s schedule the first meeting to actually define such a process, and who should “own” it.
Duration:** 5-10 minutes?

Note this Show & Tell session will happen just couple of hours before a X/Twitter Space organised by Matthew Capps on Node Diversity with people from various orgs working on a node.
My proposal:
Topic: Using Antithesis to test Cardano node(s): Current state and future plans
Duration: 5’ overview + 5’ discussion
Thanks for organising, I’d be happy to present:
Title: Towards simulation testing in Rust
Description: I’ll summarise Roland’s new stage graph API and show how it can be used to write a deterministic simulator.
Duration: 10 min including discussion
This is related to the action item “Refactor Amaru consensus to ease implementing deterministic testing” and the sessions:
