The machine was detached before it was transported
SOON starts from a narrow observation: SVM is an execution engine, not a complete settlement system. Decoupled SVM removes consensus duties from execution. SOON Mainnet runs that environment and settles on Ethereum; SOON Stack packages it for other L1 and data-availability choices.
Solana account state was not born with Ethereum-style block state roots. SOON's Merklization adds MPT structure and says state and withdrawal roots are produced every 450 slots. Those commitments are the hinge between fast SVM execution and a base layer able to judge withdrawals.
The code organization is public under Soon Labs, but the white-paper page still calls V0.1 non-final. Documentation says fault-proof support; the later MiCA paper calls zk fault-proofs an upcoming milestone. A design that can support proofs is not yet evidence that every production chain has the advertised proof and challenge path enabled.
