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 Signet: Controlled Testing Without Testnet Chaos
Signet replaces proof-of-work with a signature check, giving Bitcoin developers stable block times and reproducible test conditions. The mechanism, examined.
№ 003BitcoinBitcoin's Unspendable Outputs and the Shrinking Float
Millions of BTC are locked in addresses no one controls. The supply effect is real; the estimates are murkier than most analysts admit.
№ 004BitcoinBitcoin 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.
№ 005BitcoinBitcoin Full Node Economics: A Ten-Year Breakdown
Hardware, bandwidth, and opportunity costs all shape whether running a full Bitcoin node makes financial sense. The arithmetic, read straight.
№ 006BitcoinBitcoin Coin Selection: Fees, UTXOs, and Wallet Algorithms
Coin selection algorithms quietly determine your transaction fees and UTXO bloat. This piece breaks down Branch and Bound, dust, and consolidation strategy.
№ 007BitcoinBitcoin 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.
№ 008BitcoinBitcoin 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.
№ 009BitcoinBitcoin Compact Block Relay: Latency, Numbers, Mechanics
Compact block relay cuts Bitcoin's propagation bandwidth by ~98%. BIP 152 explained with figures, a worked example, and misconceptions addressed.
№ 010BitcoinWhy Bitcoin's Timechain Makes Censorship Very Costly
Bitcoin's block structure makes retroactively censoring a confirmed transaction ruinously costly. Here's the exact mechanism, with numbers.
№ 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.
№ 012BitcoinBitcoin Halving and Transaction Fees: What Changes
The block reward halving cuts miner subsidies, not fee revenue. Here's the exact mechanism, with numbers, and why the distinction matters.
