Bitcoin Taproot Scriptpath Spending: What the Chain Reveals
Scriptpath spending exposes your Merkle tree depth to every node operator. The mechanics, the fingerprinting risk, and what wallet developers are missing.
№ 002BitcoinTaproot On-Chain: Keypath vs Scriptpath Spending
A Taproot output looks uniform until it's spent. The witness field reveals exactly which path was taken, and how much it exposes about your setup.
№ 003BitcoinBitcoin Taproot Key Path Spending and Script Privacy
Taproot key path spending makes complex Bitcoin contracts indistinguishable from simple payments. The mechanism, the limits, and why adoption breadth matters.
№ 004BitcoinBitcoin 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.
№ 005BitcoinBitcoin's Dandelion Protocol and Transaction Origin Privacy
Dandelion splits Bitcoin propagation into stem and flood phases to defeat IP-to-transaction correlation. Mechanics, real tradeoffs, and deployment status.
№ 006BitcoinBitcoin 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.
№ 007BitcoinBitcoin Silent Payments: Unique Addresses via BIP-352
BIP-352 lets senders derive a fresh Bitcoin address from your published keys alone, no coordination, no on-chain fingerprint. The mechanism, plainly explained.
№ 008BitcoinBitcoin Tapscript: Conditional Spending, Hidden Branches
Tapscript lets Bitcoin transactions spend one condition while keeping all others permanently hidden. The exact mechanism, with a worked example.
№ 009BitcoinBitcoin Compact Filters: Private Light Client Sync
BIP 157/158 compact filters let Bitcoin light clients verify transactions locally without exposing addresses to any full node. The mechanism, plainly explained.
№ 010BitcoinBitcoin SPV Bloom Filters and the Privacy Leak
SPV bloom filters were designed to obscure your addresses from nodes, the intersection attack math shows why they don't, and what actually works instead.
№ 011BitcoinBitcoin Network Topology: Speed vs Privacy Explained
How Bitcoin's peer-to-peer topology shapes how fast your transaction spreads and how private it stays. The tradeoff most guides skip entirely.
