If you believe in better representation for Cardano, do you think proximity bias is a problem worth solving? Is it a priority?

I invite you to join the forum discussion where I'm proposing we co-author an improvement proposal with the Cardano community across Japan, USA, UK, and Latin America.

Bonus: You can now download the framework of ecosystem roles, relationships, and sector definitions we used to create the Ecosystem Maps. I've published this in the forum post. These definitions were validated by 20 Key Opinion Leaders (KOLs) in Cardano.

The Intersect Cardano Product Committee is running this survey with the aim to gather initial input which will help create a Cardano roadmap proposal. Please respond to it. https://docs.google.com/forms/d/e/1FAIpQLScBcVsUDfT1yTccitYGgupeNHe33AkuAbCREgeKbIjAht8AjA/viewform

IOG's October SPO Call occurs this Thursday, 15:00 UTC

🔹 At this SPO call we're introducing a new open discussion segment; topic: "SPO interest group at Intersect: imagine a focused institutional vehicle for serving the SPO community, by and for SPOs and their partners, what could that look like?"

🔹 We'll also hear updates from IO Engineering and Intersect's hard fork working group and Parameters Committee.

You can add the call to your calendar here: https://evt.to/egeoeueaw

We look forward to speaking with you!

Greetings SPOs! We're doing an open discussion segment at the SPO call this coming Thursday.

Topic: "SPO interest group at Intersect: imagine a focused institutional vehicle for serving the SPO community, by and for SPOs and their partners, what could that look like?"

What good could it do? What challenges would it face? Maybe it could help aggregate and support a lot of the existing work and sub-communities out there?

The full details for this call will be out Monday, but wanted to give you a heads up to get the thoughts flowing. Have a good weekend! 💪

IOG's September SPO Call occurs this Thursday, September 5th.

🔹 At this SPO call, we'll review the hard fork and the past few days of proceeding into the Conway era, discuss with Intersect's Hard Fork Working Group, and look forward into the SPO role in bootstrapping Cardano governance going ​forward.

🔹 The agenda will include panelists from the IO Engineering and Intersect's Hard Fork Working Group. We encourage you to come with your thoughts and questions as we will take time for discussion on each topic. This is a chance to come talk with these teams, to build understanding and relationship.

We look forward to speaking with you!

Cardano node v.9.1.1

Greetings SPOs, as we recently shared, the hard fork working group identified that ledger state snapshots break ledger replay in the Conway era under mainnet conditions.

👉 We now have a hotfix in v.9.1.1.

Impact:
If you restart your node with node version 9.0.0 or node version 9.1.0 following the Chang hard fork, you must replay the chain from the genesis block each time it restarts. This can take around 90 minutes.

The hotfix (node version 9.1.1) will prevent nodes from replaying from Genesis and instead replay as normal. If an upgrade is made from an earlier version than node 9.0.0, then one replay from Genesis will be required, but the node will behave normally.

Actions and notes:
- Action: It is recommended that you avoid restarting your node until this hotfix is applied (including automated restarts). Tool providers may stagger node restarts until they have upgraded to maintain adequate service.
- Node v.9.1.1 is available at: https://bit.ly/NV911
- Details of the hotfix and other possible mitigations can be found in the following document: https://bit.ly/MCLSD

Issue notice - Greetings SPOs! And congrats on a successful hard fork.

👉 Be aware that Intersect's hardfork working group has identified that ledger state snapshots break ledger replay in the Conway era when nodes have transitioned from Babbage under mainnet conditions.

Impact:
If you restart your node before 12:00 UTC on 2nd September 2024, you should be unimpacted. After that time, if you restart, you will need to replay from genesis.

A hotfix (version 9.1.1) is in preparation to avoid this and will be made available once testing has been completed - likely in the coming hours. The hotfix will avoid nodes having to replay from genesis, and instead replay as normal. Some relays, and any other nodes on scheduled automatic restarts, may be impacted if restarted prior to upgrading to the hotfix.

Actions and notes:
- Action: It is recommended to avoid restarting your node until the hotfix is released. The hotfix, node version 9.1.1, will be available in the coming hours via
https://github.com/IntersectMBO/cardano-node/releases
- Notes: For anyone with automated restarts (such as relays) it’s advisable to consider changing your restart to before 12:00 UTC on 2nd September 2024, or after upgrading to hotfix 9.1.1

Information about the hotfix will be published here as soon as it is released. For technical support or queries, head over to our hard fork working group Discord channel:

Chang technical Q&A

Join IO Engineering an other members of the HFWG Thursday at 2pm UTC for a final technical Q&A covering what to expect leading up to the hardfork, providing support, and reiterating what anyone not yet caught up with the rest of the ecosystem should do to prepare for the Chang Hard Fork.

ICYMI 👀 - Intersect's Hard Fork Working Group has set the hard fork date: September 1st.

The agenda for this event is as follows:

Network update (10m)
- HF lead up and event, what to expect
Review of upgrade info for devs (15m)
- costplan and reference scripts
- plutus v1/v2 // v3
- migrating from v2 to v3 + CIP 69
Structured Q&A (15m)
Closing (5m)

We hope to see anyone at this call who is catching up or is just interested in engaging with the HFWG— all systems go!

Greetings! 👋 re: Open office session and preprod fork.

The IO Engineering team, along with some other members of Intersect's Hard Fork Working Group (HFWG), are having an open office session, Monday 3-3:45pm UTC, to provide support and answer questions about upgrades for the Chang hard fork. Some additional reminders:

🔹 Mainnet hard fork target: September 1st. Intersect announced on Friday that based on consensus of the HFWG, the Mainnet hard fork target has been moved to September 1st.

🔹 Preprod forked-- We do recommend using Preview to test features before they get to Mainnet, but if you planned to test on Preprod instead, now is the time! 🙂

🔹 If you'd like to review the recording and notes from our past developer readiness walkthroughs, you can do that here:

Do we need a set of standards for defining ecosystem roles, relationships and sectors?

Would this be worthy of writing a Cardano Problem Statement?

https://forum.cardano.org/t/ecosystem-maps-do-we-need-a-set-of-standards-for-defining-ecosystem-roles-relationships-and-sectors/135155/1

The target for mainnet hardfork is Tuesday 27th August, with a final go/no go decision scheduled for early Friday 23rd August. https://x.com/IntersectMBO/status/1825946121765896609
