Blockchain Bridge Verification: Optimistic vs ZK Proofs
Optimistic bridges wait for objections; ZK bridges prove correctness first. The security tradeoffs are starker than most explanations admit.
№ 110AnalysisRecursive STARK Proofs: Flat Verification Costs Explained
Recursive STARKs aggregate thousands of proofs into one fixed-cost verification. The mechanism, the trade-offs, and a worked example.
№ 111AnalysisFinality Reversion vs. Reorganization in Proof-of-Stake
A finality reversion breaks a cryptographic guarantee; a reorg is a race condition. The difference determines whether settlement is statistical or binding.
№ 112RegulationTornado Cash After Sanctions: Why the Contract Kept Running
OFAC sanctioned Tornado Cash in 2022, but the core smart contract kept processing funds. The mechanic behind that gap, and what it means for DeFi regulation.
№ 113EthereumEthereum History Expiry: Decentralization vs Practicality
Ethereum's history expiry proposals would shrink node storage dramatically, and shift who bears the burden of keeping the chain's memory intact.
№ 114BitcoinBitcoin 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.
№ 115DeFiNegative Funding Rates on Perpetual Swaps Explained
Negative funding rates flip the usual incentive: shorts pay longs. Learn the mechanics, what causes them, and how arbitrageurs exploit the gap.
№ 116EthereumEVM Object Format: Code and Data, Finally Separated
EOF gives Ethereum's bytecode a defined header, typed sections, and deploy-time validation. What the mechanics change, and what they don't.
№ 117EthereumValidator Client Diversity and Ethereum Safety
A majority-client bug can finalize a bad block permanently, understand why the validator layer carries more systemic risk than the execution layer.
№ 118BitcoinBitcoin 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.
№ 119DeFiGovernance Attacks: Vote Buying vs. Delegation Exploits
Vote buying and delegation exploits both hijack on-chain governance through opposite mechanics, and the defenses that stop one are useless against the other.
№ 120SecurityHow DeFi Price Oracles Fail Under Flash Loan Attacks
Flash loans and slow manipulation break oracles in opposite ways. Understanding the mechanics helps you see why no single fix solves both problems.
