Bitcoin Hashrate Escrow and Merged-Mined Sidechains
Hashrate escrow lets Bitcoin miners secure sidechains without a second consensus system, the exact mechanism, BIP 300 numbers, and honest caveats included.
№ 002BitcoinBitcoin Miniscript: Complex Spending Conditions Explained
Miniscript compiles human-readable Bitcoin spending policies into verifiable, non-malleable Script, concrete mechanism and a worked treasury example inside.
№ 003BitcoinBitcoin'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.
№ 004BitcoinBitcoin Sighash Flags: Partial Signing Explained
Sighash flags let Bitcoin signers commit to only part of a transaction, the mechanics, the real tradeoffs, and what each flag actually does.
№ 005BitcoinBitcoin Transaction Pinning and Fee Bumping Reliability
Transaction pinning can trap a Lightning channel close at a low fee rate, blocking CPFP and RBF. The mechanics, the stakes, and the fixes underway.
№ 006BitcoinBitcoin Covenant Proposals: Security Assumptions Compared
CTV, CSFS, APO, and CAT rest on structurally different trust models. A mechanical breakdown of what actually separates them, and why it matters.
№ 007BitcoinBitcoin Script Cannot Read External Data
Bitcoin Script is a sealed execution environment with no I/O. This piece traces the exact mechanism, the design reasoning, and what DLCs build around it.
№ 008BitcoinBitcoin Proof-of-Work: Why Blocks Cost Real Energy
Bitcoin's Hashcash mechanism forces miners to burn electricity to produce valid blocks. The energy expenditure is the security model, not a design flaw.
№ 009BitcoinBitcoin Timelocked Multisig for Inheritance Planning
Timelocked multisig scripts can serve as a Bitcoin dead-man's switch. Here are the mechanics, the design tradeoffs, and the failure modes.
№ 010BitcoinBitcoin Anti-Fee-Sniping: Mechanism and Miner Incentives
Anti-fee-sniping uses nLocktime to make block reorgs unprofitable. Learn the exact mechanism, the privacy tradeoff, and why it matters more each halving.
№ 011BitcoinBitcoin 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.
№ 012BitcoinBitcoin Script Has No Loops: Security by Design
Bitcoin Script omits loops entirely, not as a limitation, but as a deliberate defense against Denial-of-Service attacks on every node in the network.
