[Starknet mainnet completes v0.13.2 upgrade, supports parallel execution and block packaging] Golden Finance reported that Starknet announced that it has completed the Starknet v0.13.2 (Bolt) upgrade on the mainnet, supporting parallel execution and block packaging (Block packing). Parallel execution enables transactions within the Starknet sorter to be executed simultaneously, and block packaging batches multiple L2 blocks into a special application recursive proof. Through block packaging, each Starknet state update processes multiple Starknet blocks, allowing batch processing of L1 fixed costs.
