The Plomin naming proposal stands at 76.5% of DRep power at the close

Plutus prices for 12 new operations take effect

Plutus V3 Cost Model Parameter Changes Prior to Chang#2 took effect at the start of epoch 526, one epoch after its ratification. Intersect filed it in epoch 519. Its document says the change was recommended by Intersect’s Parameter Committee and that the new values were validated by the Plutus Core developer team at IO Engineering against the same reference machine as the existing ones.

The update adds prices to the Plutus cost model for 12 operations that the hard fork to protocol version 10 would bring: 11 bitwise operations and RIPEMD-160, a hash function that the document says allows Bitcoin addresses and transactions to be verified on chain. It changes the price of no existing operation. The document states that the operations would not be available before that hard fork, and that the prices were set so that they could be used once the hard fork took effect.

All seven committee members found it constitutional, two of them in epoch 525, after the ratification. Under the bootstrap rules of CIP-1694 a committee vote was enough to change protocol parameters, so DReps and pools had no vote on it. The review of epochs 523 to 525 has the committee’s reasons and the first attempt at the same update, which expired at the start of epoch 525.

Four DReps carry most of the late yes power on the Plomin name

Rename the Chang 2 Hard Fork to the Plomin Hard Fork was in its last three epochs of voting, which ended at the start of epoch 529. Intersect filed it in epoch 522 for its Hard Fork Working Group, in a document by Adam Dean and Adam Rusch. It asks for the coming hard fork to be named in memory of Matthew Plomin, a community contributor who founded USDM, a stablecoin on Cardano fully backed by dollar reserves, and who died in November 2024. As of the close of epoch 528 it stood at 76.5% of DRep power, with 209 DReps voting yes, 9 no and 8 abstaining. All 95 pool votes recorded by then were yes, a yes share of 7.2% of pool stake.

Yes votes cast in epoch 528 carried ₳353.0M of DRep power at that epoch’s readings, and those cast in epochs 526 and 527 together ₳57.4M. Four DReps who voted yes in epoch 528 held ₳301.0M of it: the Eternl DRep Committee with ₳123.2M, BTBF_XSP with ₳73.6M, CryptoCrow with ₳54.2M and Ryan Jones_Maestroman with ₳49.9M. Sebastien Guillemot セバ, with ₳98.2M the second largest DRep to vote in these three epochs, abstained in epoch 527.

jonahkoch, voting yes in epoch 527, wrote that Matthew Plomin’s move from traditional finance to blockchain developer made him the kind of bridge builder the ecosystem needs. Wada DRep abstained in epoch 527, writing that the old name “has already traveled” and was familiar to the community with the upgrade so close, and that it would be proper for Intersect to dedicate a later hard fork, one aligned with governance or community expansion, to him.

Five of the seven committee votes on the Plomin name came in these three epochs. The Cardano Foundation and Emurgo voted yes in epoch 527, and the Eastern Cardano Council abstained, writing that the interim committee should abstain on information actions that do not measure sentiment for a future action to be enacted on chain. The Intersect Constitutional Council found it constitutional in epoch 528, and Input Output voted yes the same epoch. Input Output wrote that it made an exception to its policy of voting only on information actions that call for constitutional adjudication, because the community naming the first hard fork initiated by an on chain governance action was “a moment of unique historic significance”. As of the close of epoch 528 six members had voted yes and one had abstained.

Delegation to DReps rises ₳376.5M in one epoch

At the epoch 528 reading, 592 DReps held ₳2.14B of delegated power, ₳399.9M more than at epoch 526 and the highest reading since epoch 508. ₳376.5M of that rise came between the epoch 527 and epoch 528 readings. The ten largest DReps held 44.4% of the power at epoch 526 and 44.8% at epoch 528.

The count of DReps with a vote in the previous twelve epochs rose from 192 to 205, the most since epoch 508, while 392 of the 592 holding delegated power had cast none in that period. Across the three epochs DReps cast 67 votes, pools 26 and committee members 5, 98 in all with superseded votes included, and 65 distinct DReps and 26 pools cast a final vote. The treasury reading rose ₳8.9M to ₳1.62B. No treasury withdrawal could yet be proposed under the bootstrap rules.
