№ 014EthereumEthereum Gasper Slashing: Attestation Rules and Penalties
Gasper punishes double voting and surround votes with scaled ETH penalties. The math, the failure modes, and why slashing protection databases matter.
№ 015EthereumEthereum's Fork Choice Rule and Late Attestations
How Ethereum's LMD-GHOST handles attestations that arrive after the voting deadline, and what it means for chain security.

Gasper powers Ethereum's finality. Learn how Casper FFG and LMD-GHOST fork choice combine to keep the chain safe and live.
№ 018EthereumEthereum Attestation Aggregation Explained
Ethereum's attestation aggregation shrinks consensus bandwidth by orders of magnitude while keeping fault tolerance intact. The actual mechanism, examined.
№ 019EthereumEthereum 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.
№ 020EthereumEthereum 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.
№ 021EthereumEthereum Proposer Boost: Stopping Short-Range Reorg Attacks
Proposer boost adds a 40% committee-weight bonus to timely blocks, raising the cost of short-range reorg attacks above rational MEV profit thresholds.

Ethereum's weak subjectivity period isn't arbitrary. Learn how validator withdrawal rates set its length and why it matters for node security.
№ 023EthereumEthereum 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.
