PVM Benchmarking [Draft 1]

Interpreter vs Recompiler vs EVM L1

This benchmark evaluates execution performance of JAM's Polkadot Virtual Machine (PVM) using two modes: an interpreter and an ahead-of-time (AOT) recompiler. All tests were performed on Tessera, a clean-room Python implementation of the PVM developed by ChainScore Labs. Benchmarks include synthetic (ADD_JUMP) and real-world (Conway's Game of Life) workloads.

How to Deploy Your Own Pallet: A Step by Step Guide

Overview of the Tutorial

With this tutorial, new para-chain developers would benefit for building custom pallets from scratch and adding that to their existing runtime. I am going to use a pallets template, modify and add custom functions to it, check for errors and give instructions about how to implement it. I love substrate framework, and would be very happy to help other developers get into substrate.

Who is this tutorial for?

Beginners into learning substrate framework, who has an understanding of blockchain runtime, storage, calls. And atleast has experience running the substrate node template with predefined pallets.
