Layer 1 and Virtual Machines
summary
Fantom claims an asynchronous BFT layer‑1 that confirms transactions in under one second and handles a few thousand EVM transactions per second with fees of cents; middleware research produces substates (chain snapshots) that shrink full‑node storage and speed historical execution 4–5× and, with parallel replay, up to 50× in experiments. Work targets a register-based VM plus compiler/interpreter and merged opcodes to cut storage and bottlenecked sload/sstore access, reporting prototype gains like sstore 6x faster and only ~2–3% extra on‑chain storage.
