Transaction Linkability in Zcash: Portrait of a Miner in a Landscape
summary
Identifies two concrete payout modes, pattern T payouts and pattern Z payouts, and gives heuristics that link mining pools to payouts: direct value matching for T and overlapping-output clustering for Z. Claims linkability rates: ~88% of miner payouts, ~84% of z2t volume, ~68% of transactions, and >95% of T2T public flows. Uses a modified BlockSci + Python library to scan ~4 million tx in ~6.5s, measures GPU vs ASIC shift (GPU share ~75% pre‑ASIC to 0% by Oct), and shows miners drop from ~60k to ~15k after ASICs. Countermeasures: larger payout intervals, frequent address rotation, shielded payouts (only Flypool supports).
