Why Some Ethereum Smart Contracts Can't Be Upgraded
Proxy patterns let developers upgrade smart contracts, but certain design choices make upgrading impossible. Here's exactly why, with concrete mechanics.
№ 326BitcoinBitcoin's Coinbase Maturity Rule Explained
Bitcoin forces miners to wait 100 blocks before spending a block reward. Here's the exact mechanic, why it exists, and what it prevents.
№ 327DeFiCascading Liquidations in DeFi: How They Work
When collateral prices fall, DeFi protocols can trigger a chain of forced sales. Here's the exact mechanism that turns a dip into a cascade.
№ 328AnalysisRecursive zk-Proofs: Scalability Without Growing Costs
Recursive zk-proofs let blockchains batch thousands of transactions into one compact proof. Here's exactly how the math stays flat as volume grows.
№ 329BitcoinHow SegWit Changed Bitcoin Transaction ID Calculation
SegWit didn't just shrink fees. It fixed a subtle flaw in how Bitcoin transaction IDs are built. Here's the exact mechanism, explained clearly.
№ 330MiningHash Rate Distribution and Bitcoin Censorship Resistance
How mining pool concentration quietly shapes Bitcoin's ability to resist transaction censorship — and what the numbers actually mean for the network.
№ 331EthereumEthereum 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.
№ 332BitcoinWhy High Bitcoin Fees Don't Always Mean Faster Confirmation
A higher fee doesn't guarantee a faster Bitcoin confirmation. Here's the exact mechanics of mempool prioritisation, and where the logic breaks down.
№ 333SecuritySybil Attacks on Nakamoto Consensus: The Real Cost
Why flooding a proof-of-work network with fake identities doesn't work: the economic mechanics that make Sybil attacks prohibitively expensive.
№ 334AnalysisProof-of-Stake Slashing Conditions: Ethereum vs Competitors
Slashing rules vary wildly across PoS networks. Here's how Ethereum, Cosmos, Polkadot and Solana handle validator penalties and why the differences matter.
№ 335EthereumWhy Layer-2 Rollups Post Calldata to Ethereum
Rollups don't store state on Ethereum — they post calldata. Here's exactly why that choice saves 10-100x in gas and what it actually guarantees.

Bitcoin stops double spending without a bank using unspent transaction outputs. Here's the exact mechanism, with a worked example.
