BlockSTM: Scaling Blockchain Execution with Rati Gelashvili | a16z crypto research talks

BlockSTM is a parallel execution engine for smart contracts, built around the principles of Software Transactional Memory. Transactions are grouped in blocks, and every execution of the block must yield the same deterministic outcome. Here, Here, Rati Gelashvili (Aptos) explores how BlockSTM further enforces that the outcome is consistent with executing transactions according to a preset order, leveraging this order to dynamically detect dependencies and avoid conflicts during speculative transaction execution. At the core of BlockSTM is a novel, low-overhead collaborative scheduler of execution and validation tasks.
