Yul is part of a greater family of EVM assembly languages

its basically EVM assembly wrapped into a language with some Ssyntactic sugar

What's great about that is that the only thing you need to write Yul is an understanding of the EVM. Looking at Yul contracts won't really get you to that point

So, let's get a bit of a deeper understanding of the EVM

What is an EVM

Consider Ethereum to be a global computer (with each node having its own permanent data store) and EVM is the processor. It basically handles smart contract deployment and execution. It is just a computation engine, and as such provides an abstraction of just computation and storage, similar to Java Virtual Machine(JVM).

The EVM executes its own bytecode intstruction set which higher level smart contract languages such as LLL, Serpent, Mutan or Solidity are compiled into. The EVM does not require to have any scheduling capability because Ethereum clients run through verified block transactions to determine which smart contract needs executing and in which order. This mechanism makes EVM a single-threaded mechanism.

  1. A Turing machine is a finite (there are a limited number of states, such as a coin toss will have only two states: HEADS or TAILS) state machine that has an unlimited supply of paper tape that it can write on and read back.
