Add size checks for DKG transcripts before constructing system transactions: reject empty transcripts and those exceeding 100MB. The weighted DKG transcript size scales at ~336 bytes per weight unit (3×G1 + 2×G2 = 3×48 + 2×96). With equal weights, 100MB supports ~312K validators; with average weight ~20 per validator, ~15K validators. Note: MAX_DKG_TRANSCRIPT_BYTES is a consensus-critical parameter. Changing it requires a coordinated upgrade across all nodes.
