Bitcoin 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.
№ 218SecurityConfidential Asset Protocols: Hiding Amounts on Chain
Pedersen commitments and range proofs shield transaction amounts on-chain while preserving cryptographically sound audit trails for regulators and investors.
№ 219EthereumValidator 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.
№ 220EthereumEthereum 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.
№ 221BitcoinBitcoin Script Has No Loops: Security by Design
Bitcoin Script omits loops entirely, not as a limitation, but as a deliberate defense against Denial-of-Service attacks on every node in the network.
№ 222EthereumCryptographic Accumulators and Stateless Clients
Cryptographic accumulators let blockchain clients verify transactions without storing full state, the mechanism, real tradeoffs, and decentralization stakes.
№ 223SecurityReplay 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.
№ 224EthereumEthereum 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.
№ 225DeFiDeFi Oracle Delays: Manipulation-Resistance by Design
DeFi protocols deliberately lag price feeds to make manipulation costly. The tradeoffs between TWAP windows, latency risk, and liquidation accuracy explained.
№ 226BitcoinBIP-32 HD Wallets: How Key Derivation Actually Works
BIP-32 derives millions of Bitcoin keys from one seed without exposing the root. The exact mechanism, the hardening tradeoff, and where the real risks sit.
№ 227SecuritySilent Inflation Bugs in Zero-Knowledge Proof Systems
ZK inflation bugs mint tokens from nothing while every proof verifies clean. The mechanism, the failure modes, and what a real detection framework requires.
№ 228EthereumEthereum 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.
