Ethereum Proposer Boost: Stopping Short-Range Reorg Attacks
Proposer boost adds a 40% committee-weight bonus to timely blocks, raising the cost of short-range reorg attacks above rational MEV profit thresholds.
№ 134BitcoinBitcoin 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.
№ 135EthereumEthereum Weak Subjectivity Period: How It's Calculated
Ethereum's weak subjectivity period isn't arbitrary. Learn how validator withdrawal rates set its length and why it matters for node security.
№ 136MiningMiner Fee Sniping: The Risk That Grows With Each Halving
Bitcoin's block subsidy suppresses fee sniping today. As it declines toward zero across successive halvings, the incentive math shifts, and the stakes rise.
№ 137EthereumEIP-4844 Blob Expiry and Data Availability Gaps
Blob data prunes after ~18 days. For fraud provers running multi-round disputes, that window is tighter than it looks, and the archiver gap is real.
№ 138SecurityBitcoin Script Stack Evaluation: Order Creates Bugs
Bitcoin Script's stack-based execution order produces subtle, costly bugs in complex spending conditions, mechanics and a worked example examined.
№ 139EthereumEthereum Slashing Meets the Withdrawal Queue
When a slashing event hits a validator already in Ethereum's exit queue, two penalty timers run simultaneously. The math and mechanics, laid out plainly.
№ 140EthereumEthereum Blob Pruning and Rollup Data Availability
Ethereum deletes blob data after ~18 days. What that means for rollup security, fraud proofs, and the assumptions baked into Layer 2 design.
№ 141BitcoinBitcoin Mempool Replacement Policies Explained
Bitcoin nodes apply different replacement rules to the same transaction. The mechanics, tradeoffs, and practical fixes for a stuck or rejected bump.
№ 142MiningBitcoin Block Template Construction Explained
How miners pick which transactions fill a block, why fee rate alone doesn't decide it, and what dependency graphs actually do to your wait time.
№ 143SecuritySmart Contract Proxy Storage Collision Explained
Proxy patterns enable smart contract upgrades, but storage slot collisions can silently corrupt funds, the mechanism, the tradeoffs, and what auditors check.
№ 144SecurityBulletproofs: 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.
