Ethereum's Fork Choice Rule: Tie-Breaking in LMD-GHOST
When two Ethereum blocks carry identical attestation weight, a deterministic root-hash rule decides the winner, the mechanic explained, with a worked example.
№ 002EthereumEthereum Gasper: Proposer Slashing Explained
Gasper slashes validators who sign two blocks at the same slot. Mechanism, correlation penalty math, and a concrete worked example.
№ 003EthereumGasper Attestation Timing: Slot Weights Explained
Gasper cuts attestation rewards sharply with each slot of delay. The precise mechanic, the three scoring components, and worked numbers.
№ 004EthereumEthereum Attestation Aggregation Explained
Ethereum's attestation aggregation shrinks consensus bandwidth by orders of magnitude while keeping fault tolerance intact. The actual mechanism, examined.
№ 005EthereumEthereum Validator Exit Queue and Slashing Explained
How Ethereum's exit queue and slashing penalties interact during withdrawal, the mechanics, the math, and what validators actually face.
№ 006EthereumEthereum Withdrawal Queue and Its Real Cost to Yield
Ethereum's activation and exit queues impose a computable drag on effective yield. The mechanism, the arithmetic, and what solo stakers typically miss.
№ 007EthereumEthereum Inactivity Leak and Clustered Validator Risk
How Ethereum's inactivity leak punishes geographically clustered validators harder than spread-out ones, and what the math actually looks like.
№ 008EthereumEthereum 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.
№ 009EthereumEthereum 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.
№ 010EthereumEthereum 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.
№ 011EthereumValidator 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.
№ 012EthereumValidator Correlation Risk and Slashing in Staking Pools
Why slashing penalties scale with how many validators fail together, and how staking pool design either contains or amplifies that damage.
