Ethereum Proof-of-Stake Finality Explained
Ethereum's PoS finality isn't instant. Here's the exact two-epoch mechanic that determines when a block is truly safe to treat as settled.
№ 086EthereumWhy Some Ethereum Smart Contracts Can't Be Upgraded
Proxy patterns let developers upgrade smart contracts, but certain design choices make upgrading impossible. Here's exactly why, with concrete mechanics.
№ 087AnalysisRecursive zk-Proofs: Scalability Without Growing Costs
Recursive zk-proofs let blockchains batch thousands of transactions into one compact proof. Here's exactly how the math stays flat as volume grows.
№ 088EthereumEthereum Verkle Trees: Smaller Proofs, Lighter Nodes
Verkle trees shrink Ethereum state proofs from megabytes to kilobytes and could let nodes sync without storing the full chain. Here's how.
№ 089AnalysisProof-of-Stake Slashing Conditions: Ethereum vs Competitors
Slashing rules vary wildly across PoS networks. Here's how Ethereum, Cosmos, Polkadot and Solana handle validator penalties and why the differences matter.
№ 090EthereumWhy Layer-2 Rollups Post Calldata to Ethereum
Rollups don't store state on Ethereum — they post calldata. Here's exactly why that choice saves 10-100x in gas and what it actually guarantees.
№ 091EthereumWhy Ethereum Validators Miss Attestations Without Ejection
Ethereum validators can skip attestation duties and keep their stake. Here's the exact penalty math and the threshold that actually gets you removed.
№ 092SecurityWhy Smart Contract Audits Miss Reentrancy Bugs
Single-function reentrancy is well-understood. Cross-function and cross-contract variants still slip through audits. Here's exactly why, and how.
№ 093EthereumEthereum Beacon Chain Validator Slashing Explained
How Ethereum's Beacon Chain detects and punishes equivocation: the mechanics of slashing, whistleblower rewards, and the correlation penalty explained clearly.
№ 094AnalysisHow MEV Changes Validator Incentives in Proof-of-Stake
MEV reshapes what validators actually optimize for in PoS systems. Here's the concrete mechanics, the real tradeoffs, and what most guides skip.
№ 095SecurityHow zk-SNARKs Stay Small Without Breaking Soundness
zk-SNARKs produce tiny proofs that verify in milliseconds. Here's the exact mechanism that makes them compact without letting cheaters through.
№ 096EthereumWhy Ethereum Gas Prices Spike Unexpectedly
Block space can look half-empty yet gas prices still spike. Here's the precise mechanism behind Ethereum fee surges most guides never explain.
