Parallel Smart Contracts for Speed

Threading in Solidity to Optimize Execution

**Some incomplete thoughts on parallel execution **

Smart contract code is traditionally executed sequentially. Meaning code executes a, b, c, d, and so on.

Solidity, the programming language used for developing smart contracts on the Ethereum blockchain has evolved, however, to fulfill the requirement for higher performance as onchain activity grows, with concurrent and parallel execution.

Meaning code executes abcd all at once, in parallel, across threads.

A thread in computer science is short for a thread of execution. Threads are a way for a program to split itself into two or more simultaneously (or pseudo-simultaneously) running tasks. (Source: Thread)

Threads and processes differ from one operating system to another but, in general, a thread is contained inside a process and different threads in the same process share the same resources while different processes in the same multitasking operating system do not.

In this story we will explore multi-threading in Solidity.

Addressing challenges related to concurrency, parallelism, and atomicity. We will delve into the techniques and best practices for handling multiple threads within smart contracts, ensuring security and maintaining atomicity.

Best Practices for Multi-Threading in Solidity:

1. Isolation of Critical Sections:

• Identify critical sections in your code that require exclusive access to shared resources and protect them using synchronization mechanisms.

2. Minimizing State Modifications:

• Reduce the frequency of state modifications to minimize the chances of conflicts and improve efficiency.

3. Careful Use of Time Delays:

• Implement time delays cautiously to avoid potential reentrancy and race conditions.

4. Embracing Off-Chain Processing:

• Utilize off-chain processing whenever possible to distribute the workload and enhance parallelism.

5. Thorough Testing and Auditing:

• Perform rigorous testing and security audits to identify potential vulnerabilities and ensure the reliability of multi-threaded smart contracts.
