Updates

• The main discussion topic has been the SPO poll, results are under interpretation, however here is a brief summary of what was discussed:

  • Asked questions:

    • Which (k and min fee) setup would you prefer to be put in place from Q3 2023 onwards?

      • Keep k at 500 and minPoolCost at 340 ada

      • Keep k at 500 and halve minPoolCost to 170 ada

      • Increase k to 1000 and keep minPoolCost at 340 ada

      • Increase k to 1000 and halve minPoolCost to 170 ada

      • I would prefer to abstain

      • None of the provided options

• Preliminary results:

• Total SPO votes: 797

Keep k at 500 and minPoolCost at 340 ada	8.78 %
Keep k at 500 and halve minPoolCost to 170 ada	12.30 %
Increase k to 1000 and keep minPoolCost at 340 ada	23.84 %
Increase k to 1000 and halve minPoolCost to 170 ada	45.80 %
I would prefer to abstain	0.63 %
None of the provided options	8.66 %

• Total participated stake: 10.87b ada

Keep k at 500 and minPoolCost at 340 ada	2.08b
Keep k at 500 and halve minPoolCost to 170 ada	2.73b
Increase k to 1000 and keep minPoolCost at 340 ada	1.47b
Increase k to 1000 and halve minPoolCost to 170 ada	3.00b
I would prefer to abstain	79.56m
None of the provided options	1.51b

• There was a variety of SPO voters. If we see the different filters the results mainly point to Increase k to 1000 and halve minPoolCost to 170 ada, however the results are not conclusive - especially for keeping or increasing k.

• Next steps:

  • Results are now under interpretation by the parameter committee and the Cardano community.

  • The advisory groups will have to consider the poll outcome from the perspective of their parameters. Sam Leathers and his group will consider this from an economic perspective, Markus and his group from a technical perspective and Neil from a networking perspective. Then they will come back with recommendations at the next meeting, and the whole committee can come to an official recommendation.
