Bitcoin'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.
№ 002BitcoinBitcoin 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.
№ 003BitcoinBitcoin 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.
№ 004BitcoinBitcoin 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.
№ 005SecurityBulletproofs: Range Proof Verification at Logarithmic Scale
Bulletproofs cut Monero range proof sizes from ~13 KB to under 800 bytes. The mechanism is a recursive inner product argument, and the math holds up.
№ 006DeFiMerkle Proofs and Selective Disclosure in Digital Identity
Merkle proofs let you prove one credential claim without exposing the rest. Here is the exact mechanism, a worked example, and the tradeoffs that matter.
№ 007SecurityHomomorphic Encryption vs Zero-Knowledge Proofs
HE computes on encrypted data; ZK proofs verify claims about it. Understanding the mechanical difference prevents costly architectural mistakes.
№ 008BitcoinBitcoin 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.
№ 009BitcoinBitcoin 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.
№ 010SecurityConfidential Asset Protocols: Hiding Amounts on Chain
Pedersen commitments and range proofs shield transaction amounts on-chain while preserving cryptographically sound audit trails for regulators and investors.
№ 011SecurityPedersen Commitments and Confidential Transactions Explained
Pedersen commitments hide transaction amounts while letting anyone verify no coins were created from nothing. The exact mechanism, step by step.
№ 012BitcoinBitcoin 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.
