Ethereum Casper FFG: Surround vs Double Votes Explained
Casper FFG defines two distinct slashing conditions with different attack surfaces. The mechanical difference between surround and double votes, with examples.
№ 002EthereumEthereum Weak Subjectivity Checkpoints Explained
How Ethereum's weak subjectivity checkpoints work, why new nodes depend on them, and what that means for bootstrap security assumptions.
№ 003EthereumEthereum Casper FFG: The Two-Thirds Finality Threshold
Casper FFG requires a two-thirds stake supermajority to finalize checkpoints. The mechanic, the math behind the threshold, and what breaks when it fails.
№ 004EthereumEthereum Validators: BLS Aggregation Limits and Scaling
BLS signatures cut verification cost near-constant, but aggregation routing scales with validator count. The mechanics, tradeoffs, and what breaks first.
№ 005EthereumEIP-7251 Validator Consolidation and Voting Power
EIP-7251 raises Ethereum's validator cap to 2,048 ETH, reshaping stake-weighted voting power, compounding rewards, and who actually carries the slashing risk.
№ 006EthereumEthereum Attestation Inclusion Delay Reward Explained
Ethereum pays validators proportionally for how fast their attestations land on-chain. The mechanic, the tradeoffs, and what it signals about network health.
№ 007EthereumEthereum's Gasper Consensus: Checkpoint Finality Explained
Gasper pairs LMD-GHOST with Casper FFG to finalize Ethereum blocks. The checkpoint math, the two-thirds threshold, and what irreversibility actually costs.
№ 008EthereumEthereum Weak Subjectivity Period Explained
When validator churn outpaces protocol assumptions, Ethereum's weak subjectivity window shrinks, and your node won't warn you. The exact mechanic, examined.
№ 009EthereumEthereum's Validator Activation Queue Explained
Ethereum's churn limit throttles validator entry to protect consensus stability. The mechanic, the math, and what it costs depositors who miss the timing.
№ 010EthereumEthereum's Gasper Consensus: Block Finality Explained
Gasper requires two-thirds of staked ETH to justify a checkpoint before finalizing it. The exact mechanic, the numbers, and the tradeoffs.
№ 011EthereumEthereum Validator Penalties: Inactivity Leaks vs Slashing
Inactivity leaks and slashing penalize Ethereum validators through different mechanisms. The math, timelines, and what each means for staking economics.
№ 012EthereumEthereum Penalties: Inactivity Leaks vs Slashing Explained
