Bitcoin RBF Carve-Out and Package Relay Explained
How Bitcoin's RBF carve-out rules and package relay interact during contested Lightning channel closes, and why the distinction matters.
№ 002EthereumEthereum Blob Fee Market: When Rollups Go Silent
When rollup sequencers pause at once, EIP-4844's blob fee market doesn't freeze, it craters, then whipsaws. Here's exactly how the mechanics play out.
№ 003BitcoinBitcoin Anchor Outputs: Fee Bumping Presigned Transactions
Anchor outputs let channel parties bump fees on presigned Bitcoin transactions at broadcast time, the mechanism, the carve-out policy, and its real limits.
№ 004EthereumEthereum Blob Fee Market: Target Usage and Repricing
Blob fees on Ethereum run a separate EIP-1559 loop from gas, compounding at 12.5% per block. The arithmetic behind rollup cost spikes, explained.
№ 005EthereumEthereum Blob Pruning and the Fraud Proof Timing Risk
Ethereum deletes blob data after ~18 days, a pruning schedule that creates a concrete asymmetry for anyone challenging a rollup fraud proof.
№ 006BitcoinBitcoin Drivechain: Miner-Secured Sidechain Withdrawals
Drivechain repurposes Bitcoin miners as sidechain withdrawal referees, exact mechanism, real tradeoffs, and what critics in the BIP threads actually argue.
№ 007EthereumEthereum Blob Data: Why Smart Contracts Can't Read It
Blob transactions cut rollup data costs sharply, but the EVM only ever sees a 48-byte commitment. The mechanical reason is deliberate, and worth understanding.
№ 008BitcoinBitcoin Transaction Pinning and Lightning Force-Closes
Transaction pinning can trap Lightning Network force-closes at uncompetitive fee rates, burning timelocks. The mechanics, the stakes, and the fixes in progress.
№ 009EthereumEthereum Blob Fee Burns and Validator Rewards Explained
Blob transaction fees burn separately from execution gas. Here's exactly how that splits validator accounting during L2 congestion spikes.
№ 010BitcoinBitcoin Transaction Pinning and Fee Bumping Reliability
Transaction pinning can trap a Lightning channel close at a low fee rate, blocking CPFP and RBF. The mechanics, the stakes, and the fixes underway.
№ 011EthereumEthereum Blob Fee Market vs Base Fee: The Split Explained
Ethereum's blob fees and base fees run on separate meters and diverge sharply during peak rollup demand. The mechanics, with numbers.
№ 012EthereumEIP-4844 Blob Expiry and Data Availability Gaps
Blob data prunes after ~18 days. For fraud provers running multi-round disputes, that window is tighter than it looks, and the archiver gap is real.
