  1. What does the EVM do?
    The Ethereum Virtual Macine reads executes smart contracts independently from smart contracts and CPUs. It is a code that is run by all nodes in the Ethereum network.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the Human programming language that gets compiled into Bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because the language of BTC is not turing complete, therefore very limited.

  5. What is a Turing Complete programming language?
    Turing Complete language is a complete language that can program all the necessary things a program needs to execute to solve a problem. This language allows for Loops.

    A1: The EVM is the Ethereum Virtual Machine which is basically a global computer. It runs on each node allowing the network of computers to run smart contracts.
    A2: It reads “bytecode” which is programmed in Solidity and then compiled so that the EVM can read it and execute the code.
    A3: Solidity is the programming language that developers use, it is compiled and then read by the EVM as Bytecode.
    A4:Bitcoin has limited functionality because it used Script which is not “Turing Complete”. EVM uses solidity which is Turing complete meaning it can execute a complete set of computer instructions including “loops”/
    A5: It means it can run loops and execute a complete set of programmable functions.

  4. Because Bitcoin has it’s own programming language “script” but it’s not turing complete.

  5. Turing complete language is complex language that contains all the features like loops to interact with the machine. Everything that we write can be execute.

  1. What does the EVM do?

The EVM or Ethereum virtual machine is an application that runs on all the computer nodes in the Ethereum network and its main purpose is to, read and execute all smart contracts in order to obtain data that is verifiable via consensus among the Ethereum blockchain. Also, the EVM acts as a capsule that isolates the instructions written in the smart contract and malicious actions to take place in the computer nodes.

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

The EVM can read only read smart contracts that have been compiled into byte code.

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

Solidity and bytecode have an indirect relationship, through the use of a compiler program, any smart contract written in solidity (or any other programming language) can be turned into a readable format by the EVM.

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

Because Bitcoin has a non-touring complete scripting language that limits its capabilities to a very simple transactional and store of value blockchain.

  1. What is a Turing Complete programming language?

    A Turing complete programming language is a language that, in theory, is limitless in programming possibilities.

  1. What does the EVM do?
    EVM gets compiled solidity code and uses it to tell the CPU exactly what to do for the smart contract.

  2. What is the format of the instructions that the EVM can read?
    The format of instruction is taken in bytes originating from a Solidity compiler.

  3. What is the relationship between the programming language Solidity and Bytecode? The relationship is that the original bytecode was originally Solidity code, but ran through a Solidity compiler thus extracting the bytecode for the EVM to read.

  4. Why can’t Bitcoin run the same type of complex programs as Ethereum can? This is because the Bitcoin network is not Turing Complete, meaning it cannot solve all language-based problems that most likely would be required.

  5. What is a Turing Complete programming language?
    Turing Complete language is one that can perform any computation universally.

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?
A turing complete language is a programming language able to programme complex smart contracts. It is for example able to programme loops so certain actions can be repeated.
