Homework on EVM - Questions (Updated on Dec 3 2019)

  1. What does the EVM do?

The Ethereum Virtual Machine (EVM) executes smart contracts that are deployed on the Ethereum network.

  1. What is the format of the instructions that the EVM can read?

The EVM reads instructions in Bytecode, and then executes it with the help of each nodes’ CPU.

  1. What is the relationship between the programming language Solidity and Bytecode?

Solidity is developed as a language to more easily create Bytecode, that the EVM then can read.

  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?

The bitcoin scripts are more limited in possibilities than the smart contracts on Ethereum. In contrast to Solidity, it’s not Turing complete.

  1. What is a Turing Complete programming language?

A Turing complete programming language can, in theory, do anything you tell it to do.

  3. What is the relationship between the programming language Solidity and Bytecode?
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
  5. What is a Turing Complete programming language?

Answers:

  1. Etherium Virtual Machine is used to execute the code on the network. All nodes run EVM and when each node has run the same script, concensus is reached.
  2. EVM reads instructions in bytecode.
  3. Solidity is used by the developer to create functions for smart contracts. A compiler is used to transform the instructions into bytecode.
  4. Bitcoin has a programming language called Script but this is not TC (Turing Complete). It can not execute more complex logic such as Loops and must all be handwritten.
  5. TC means it can solve all problems.

Homework: EVM

Answers below:

1. What does the EVM do?

Answer: Ethereum Virtual Machine is a piece of code installed and running on all Ethereum network computer nodes. EVM reads all the computer program instructions, performs the calculation ( i.e like for smart contract), and then EVM will communicate and tell the CPU what to do. EVM enables all computer nodes to come to and reach a consensus about the outcome.

2. What is the format of the instructions that the EVM can read?

Answer: EVM reads the compiled Byte Code format and executes the byte code instructions.

3. What is the relationship between the programming language Solidity and Byte code?

Answer: Solidity is the language used to program the computer node instructions. EVM Byte Code takes the computer node instructions, compile it so that the Ethereum Virtual Machine (EVM) that is running on each computer node hardware can read and execute those instructions.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?

Answer: Bitcoin programming language aka “Script” is not a Turing and Complete language and is too limited to run complex programs. Though it’s program is limited, Bitcoin’s “script” can run MultiSig, allowing two signatures to sign-off on a transaction. However, nothing too complex than that is possible without a Turing Complete program language.

5. What is a Turing Complete programming language?

Answer: Ethereum’s Solidity is a Turing Complete Language. With a Turing Complete language, complex instructions may be program; anything is possible with a Turing and Complete language using Solidity, such as a Smart Contract running across all Ethereum nodes.
