Bitcoin Erlay vs INV Relay: Propagation Compared
Erlay swaps Bitcoin's INV flood for set reconciliation via PinSketch, cutting relay bandwidth ~40%. The mechanism, the math, and the real tradeoffs.
№ 002BitcoinBitcoin Erlay: Set Reconciliation Explained
Erlay replaces Bitcoin's flood-based INV announcements with set reconciliation, cutting transaction bandwidth roughly 40% without sacrificing propagation speed.
№ 003BitcoinBitcoin Erlay: Peer Selection and Mempool Privacy
Erlay cuts Bitcoin's relay bandwidth by ~84%. The peer selection logic, decided before any transaction data exists, is where the privacy argument lives.
№ 004BitcoinBitcoin Erlay Fanout Phase: Peer Selection Explained
Erlay's fanout phase pushes transactions to a randomized peer subset, not the whole network. A close look at the mechanism, its privacy logic, and its limits.
