# Per-node divergence + topology sweep (scaled k). Headline: per-node D_est spread stays ~0
|
|
# (window agreement ~1) while topology/latency shift the shared mean accuracy, which uncles
|
|
# recover. Two propagation models are swept, each covering a real-world regime:
|
|
# * regular : direct block gossip over a random d-regular graph. Realistic links are sub-slot
|
|
# (~0.05-0.2 slot = 50-200 ms), so forks are rare and TSI barely underestimates.
|
|
# * blend : the same graph, but each block is relayed through `blend_hops` random nodes
|
|
# (a mix cascade, per-hop delay ~ U(0, blend_delay_max)) before a final gossip.
|
|
# This is the multi-slot Blend-mixnet regime where forks and the stake
|
|
# underestimate appear and uncle references matter.
|
|
# Latency is in SLOTS (1 slot = 1 s). Sweep axes (cartesian product x replicates).
