Long-form technical writing on execution models, consensus, EVM foundations, and verifiable AI. Each insight makes Web3 clearer.
Editor's pickThree mature paths break past single-threaded execution — Sealevel-style deterministic pre-declaration, Block-STM-style optimistic concurrency control, and Sui-style object models. This piece compares their assumptions, developer costs, and fit with EVM compatibility.

Parallel EVM rarely fails on transfer benchmarks, but often collapses on AMM, lending, and NFT mint traffic. This article explains how conflict hotspots form, how read/write-set granularity drives conflict rates, and how peak TPS degrades under real workloads.
Optimistic concurrency control began in 1981 database research and now underpins many parallel EVMs. This primer explains the read–validate–write phases, contrasts OCC with pessimistic locking and MVCC, and names the extra determinism and Byzantine constraints blockchains add.
Three mature paths break past single-threaded execution — Sealevel-style deterministic pre-declaration, Block-STM-style optimistic concurrency control, and Sui-style object models. This piece compares their assumptions, developer costs, and fit with EVM compatibility.
Major Ethereum congestion events share one design root — the EVM executes transactions one at a time. This piece explains why raising the gas limit and EIP-1559 cannot rewrite that execution model, and how confirmation delay amplifies the single-thread ceiling.
