Ethereum Proposer-Builder Separation Explained
PBS splits block building from block proposing, reshaping MEV incentives, validator yields, and where ordering power actually concentrates.
№ 086DeFiUnclaimed Airdrop Tokens: Stranded in Smart Contracts
No sweep function means unclaimed airdrop tokens lock in a contract permanently. The mechanics, real protocol examples, and what a four-line fix looks like.
№ 087EthereumEthereum Engine API: Separating Consensus From Execution
The Engine API is the quiet wire between Ethereum's two client layers. Here's exactly how it works and why the split matters.
№ 088EthereumValidator 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.
№ 089EthereumEthereum SSZ vs RLP: The Serialization Shift Explained
SSZ replaced RLP on Ethereum's consensus layer. The two formats differ in philosophy, Merkle support, and developer impact, a concrete technical breakdown.
№ 090EthereumCryptographic Accumulators and Stateless Clients
Cryptographic accumulators let blockchain clients verify transactions without storing full state, the mechanism, real tradeoffs, and decentralization stakes.
№ 091SecurityReplay Attacks vs Double-Spends on Forked Chains
Replay attacks and double-spends differ mechanically, defensively, and in attacker effort. The distinction shapes real security decisions on forked chains.
№ 092EthereumEthereum Weak Subjectivity Checkpoints Explained
Long-range attacks can rewrite proof-of-stake history silently. This is the precise mechanism Ethereum uses to stop them, and what node operators must verify.
№ 093EthereumEthereum Validator Withdrawal Credentials Explained
BLS vs execution-layer withdrawal credentials create sharply different exit paths for dormant validators, a gap that compounds quietly and can strand funds.
№ 094EthereumHow to Stake Ethereum: The Three Honest Paths and Their Trade-offs
A clear-eyed walk through how to stake Ethereum after the Merge, from running your own 32 ETH validator to liquid staking and exchange staking, with the real risks spelled out.
№ 095EthereumEthereum Gas Fees Explained: Why You Pay and How to Pay Less
Gas is what you pay to use Ethereum. Here's how it actually works, why fees jump, and the moves that cut your costs.
№ 096AnalysisProof of Stake vs Proof of Work: Which Consensus Actually Wins?
Two ways to secure a blockchain, two very different bets. I break down how proof of work and proof of stake really differ, where each one breaks, and which I'd trust with my money.
