Ethereum 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.
№ 062SecuritySmart 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.
№ 063EthereumEthereum'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.
№ 064SecurityVerifiable 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.
№ 065AnalysisBlockchain Indexers Diverge During Chain Reorgs
Chain reorganizations expose hidden gaps between indexing services, detection latency, rollback depth, and confirmation thresholds each split data differently.
№ 066EthereumEthereum 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.
№ 067SecurityFormal 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.
№ 068DeFiPlasma 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.
№ 069EthereumEthereum 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.
№ 070EthereumLayer-Two Networks and Ethereum Security Inheritance
Not every L2 borrows Ethereum's security guarantees, the mechanical gap between those that do and those that only borrow its liquidity, explained.
№ 071SecurityKeccak-256 Preimage Resistance and Ethereum's State Trie
How Ethereum's Keccak-256 hash function blocks preimage attacks on the state trie, explained with concrete mechanics and a worked example.
№ 072AnalysisEconomic Attacks: Proof-of-Stake vs Proof-of-Work
Attack costs in PoS and PoW differ mechanically, not just in scale. A precise breakdown of what attackers spend, risk, and lose in each model.
