We updated ePrint 2026/1692 with new results on Poseidon: eprint.iacr.org/2026/1692
The paper introduces a new approach to round skipping which we denote (k+1)-wise collapsing and which enables round skipping in arbitrary CICO-k problems beyond CICO-1 and CICO-2.

tl;dr: we present an interpolation attack on 28 out of 31 rounds of Poseidon in practical time via a novel technique for partial round skipping; see ia.cr/2026/1692. 🧵⬇View quoted post on X
