Ethereum Verkle Trees and State Proof Economics
Verkle trees cut Ethereum witness sizes from megabytes to ~150 KB, reshaping costs for node operators, validators, and proof generators.
№ 002BitcoinBitcoin Erlay Fanout Phase: Peer Selection Explained
Erlay's fanout phase pushes transactions to a randomized peer subset, not the whole network. A close look at the mechanism, its privacy logic, and its limits.
№ 003BitcoinBitcoin Mempool Replacement Policies Explained
Bitcoin nodes apply different replacement rules to the same transaction. The mechanics, tradeoffs, and practical fixes for a stuck or rejected bump.
№ 004EthereumEthereum Snap Sync: State Verification Without Full History
Snap sync lets Ethereum nodes verify current state without replaying every transaction, exact mechanism, security trade-offs, and a worked example included.
№ 005EthereumEthereum History Expiry: Decentralization vs Practicality
Ethereum's history expiry proposals would shrink node storage dramatically, and shift who bears the burden of keeping the chain's memory intact.
№ 006BitcoinBitcoin Compact Filters: Private Light Client Sync
BIP 157/158 compact filters let Bitcoin light clients verify transactions locally without exposing addresses to any full node. The mechanism, plainly explained.
№ 007SecurityBitcoin Peer Discovery and Eclipse Attacks Explained
Bitcoin's peer discovery resists eclipse attacks via randomized bucketing, anchor peers, and subnet limits, but the gaps are real and worth knowing.
№ 008EthereumEthereum 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.
№ 009EthereumEthereum Node Sync: Snap Sync vs Full Archive
Snap sync gets an Ethereum node running in hours. Full archive takes days and terabytes. Here's exactly what each method stores and why it matters.
№ 010EthereumEthereum 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.
№ 011BitcoinHow Mempool Congestion Spreads Across Node Clusters
Mempool congestion doesn't hit all nodes at once. Here's how geographic propagation works and why your fee estimate can lag reality by minutes.
