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

1. What does the EVM do?
The Ethereum Virtual Machine reads and executes smart contracts.

2. What is the format of the instructions that the EVM can read?
The format in which the EVM can read instructions is Byte code.

3. What is the relationship between the programming language Solidity and Bytecode?
Smart contracts are written in the programming language Solidity. It is then compiled into Byte code so it can be read by the EVM.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
The programming language used for Bitcoin is script. This language is not able to execute complex programs. It is called a not turing complete language.

5. What is a Turing Complete programming language?

  1. What does the EVM do?

The Ethereum Virtual Machine is responsible to read the instructions from the smart contract, converted in byte code and instruct all the CPUs on the network on the required tasks to perform.

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

Byte code

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

Solidity is the language the programmer use to compile a smart contract. This contract is then compiled in byte code to communicate with the ETV

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

Because the language Bitcoin uses is not Turing complete. Bitcoin can’t implement loops.

  1. What is a Turing Complete programming language?

A Turing complete language is a fully completed language which is able to also implement loops

1 - The EVM executes smart contracts. Each node on the Ethereum network has a copy of the EVM as well as a CPU. The smart contract code is written using the Solidity language, the code is then compiled into byte code which the EVM will read then execute. To achieve consensus the EVM on each node will have to execute the code and produce the same result.
2 - The EVM will read the byte code.
3 - Solidity is the programming language that smart contracts are written in. Solidity will then compile the code into byte code which the EVM will read and execute.
4 - Bitcoin uses the Script language which is a language that is not Turing complete. This prevents Bitcoin from being able to run complex programs. The Bitcoin network will also most likely suffer from excessive spam if it was Turing complete.
5 - Turing complete languages allows for an abundance of things to be coded. Turing complete languages allow for the use of loops, this allows the software to execute 1 thing several times.

  1. What does the EVM do?
    The EVM is the part of Ethereum that handles smart contract deployment and execution. EVM sits between smart contacts and cpu it executes the smart contacts into byte code which later will be run on the cpu.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    The Ethereum Virtual Machine (EVM) is a powerful, sandboxed virtual stack embedded within each full Ethereum node, responsible for executing contract bytecode. Contracts are typically written in higher level languages, like Solidity, then compiled to EVM bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin does not have the capability to run smart contracts. Ethereum is a blockchain that was developed to support scripting and the creation of decentralized applications and ‘smart contracts’ through its virtual machine (EVM).

  5. What is a Turing Complete programming language?
    A Turing Complete system means a system in which a program can be written that will find an answer.

  • What does the EVM do?
    The EVM runs as a separate layer on top of the computers in the Eth network. It can read and execute smart contracts and serves as a layer of security due to its separation from the node computers.
    .

  • What is the format of the instructions that the EVM can read?
    Byte code

  • What is the relationship between the programming language Solidity and Bytecode?
    Instructions for smart contracts can be writter in Solidity and then run through a compiler to translate into Bytecode so the EVM can read them.

  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin Script is not turing complete and therefore only able to perform simple tasks eg Multi sig wallets.

  • What is a Turing Complete programming language?
    Turing complete programming language means you can (in theory) give instructions to the network to perform anything.
