Anatoly explains the Sealevel runtime in this blog article: https://medium.com/solana-labs/sealevel-parallel-processing-thousands-of-smart-contracts-d814b378192

TL;DR: All transactions must specify in advance which accounts are writable. All transactions that do not write in the same piece of state can be processed in parallel.
