Parallel Execution

SputnikVM is capable of doing basic parallel execution of transactions. Classic in Orbit has a blog post explaining how it works. The algorithm works like below.

• Execute all transactions in parallel and gather SputnikVM's AccountChange, without any prior checking.
• Try to apply account changes to the state trie. Take note of which addresses have been modified. If conflict is detected, re-execute that particular transaction and then continue.

The example code showing how this works in practice can be found here.
