Mainnet-parameter inference-feedback evaluation completed (T=388800 slots, f=1/30): block references keep the inferred denominator substantially closer to true stake; at delays 10/20/29, 0.959/0.882/0.759 of true stake versus 0.705/0.399/0.168 chain-only; at delay 40, chain-only falls to ~0.101 while referenced configurations reach up to ~0.986 doc
Additional simulations and figures added to the “Modelling of Network Delays” document doc
Pivot to fully permissionless sequencing: Proposal VIII adopts a public per-channel lottery (new L1 op family, no committee), with a decision map and first-pass withdrawal-exit simulations covering exit-family comparison, lottery weight during pending exits, and concentration windows doc

Abort Attribution reworked into a commitment-only + challenge-response design following the optimistic fair exchange principle: the happy path registers only hash commitments on-chain, with content disclosed on-chain only when a challenge is opened doc
Intent structure and hash computation fixed: canonical CrossZoneIntent serialization with SHA-256 commitments, so proposal_id = H(intent) serves as an openable commitment in disputes doc
Bayesian sender-attribution attack built, completing the anonymity axis alongside stake inference, with three unlinkability measures: top-1 de-anonymisation, mean true-sender posterior, and posterior entropy doc, doc
