Ethereum 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.
№ 026EthereumEIP-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.
№ 027EthereumEthereum 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.
№ 028EthereumEthereum 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.
№ 029SecuritySmart 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.
№ 030EthereumEthereum's Blob Fee Market, Explained
Ethereum runs two separate fee markets simultaneously. Blob fees and base fees move independently, and that split is what keeps rollup costs low.
№ 031SecurityVerifiable Delay Functions and Randomness Beacon Security
VDFs make on-chain randomness manipulation structurally expensive via a sequential delay no adversary can compress. The mechanics, caveats, tradeoffs.
№ 032AnalysisBlockchain Indexers Diverge During Chain Reorgs
Chain reorganizations expose hidden gaps between indexing services, detection latency, rollback depth, and confirmation thresholds each split data differently.
№ 033EthereumEthereum Validator Inactivity Leaks Explained
Inactivity leaks drain ETH stake gradually by design. The math is specific, the tradeoffs are real, and every serious validator operator should understand both.
№ 034SecurityFormal Verification vs Smart Contract Security Audit
A security audit finds likely bugs. Formal verification proves their absence mathematically. The difference in cost, time, and guarantees, laid out plainly.
№ 035DeFiPlasma Mass Exit: The Mechanism When Data Is Withheld
A Plasma operator withholds block data and every user must race to exit. The exact mechanism, its structural limits, and what it reveals about Layer 2 security.
№ 036EthereumEthereum Snap Sync: State Verification Without Full History
Snap sync lets Ethereum nodes verify current state without replaying every transaction, exact mechanism, security trade-offs, and a worked example included.
