  1. EVM is the Etherum virtual machine. this executes smart conrts into byte code which then will be run as a readble code on the cpu. It gets the consensous on the entire network.

2 EPV reads byte code

3.Solidity is the programming language that takes instructions and compiles it into bytecode so that the EVM can read it.

4 Bitcoin’s programming language Script is not Turing complete, and can only perform basic programs eg. multisig

5A turing complete language implies that the programming language is fully functional and can solve any problem it may come across. It has features like loops for example where Script does not.

The EVM (Ethereum Virtual Machine) is an application running on the Ethereum Network that acts as an intermediary between the ethereum blockchain/smart contracts and the node operators cpu’s.

The EVM reads BYTECODE.

Bytecode is the format that the EVM reads. Bytecode is complied from the ethereum programming language Solidity.

Bitcoin can’t run the same type of complex programs that Ethereum can because it isn’t Turing Complete.

A touring complete language is highly programmable. Basically in theory you can program anything you can think of.

  2. EVM is only interested in reading the byte code or smart contract.

  3. Solidity is compiled into byte code using a compiler, and the byte code then runs on the CPU.

  4. Because it using a language, Script, that is not Turing Complete.

  5. A Turing Complete Language allows for Loops to occur.

  1. What does the EVM do?
    EVM is a piece of code that all computers are running that can read smart contracts and give those instructions to your CPU to execute. Its main purpose is security because if these smart contracts were to speak directly with your CPU it could potentially take control of your CPU and compromise the entire network.
  2. What is the format of the instructions that the EVM can read?
    The format of instructions that the EVM can read is called byte code that is written with a programming language called solidity. Ethereum is also working on a new programming language called Viper. A special application called a compiler will then take the solidity code and compile the logic and instructions to create a byte code which the EVM will read and send to the CPU to execute.
  3. What is the relationship between the programming language Solidity and Bytecode?
    The relationship between the programming language Solidity and Bytecode is that it smart contracts are written in solidity and then ran through a compiler in order to spit out a Bytecode which can be sent to the CPU to execute
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin can not run the same type of complex programs like Ethereum because it does not use the same programming language. Instead it uses a much more simpler programming language called script that is not turing complete. Meaning it can not solve the most complex problems and can only solve more basic problems. It also does not have the capability of running loops because of its simplicity. However because of its simplicity it will have much higher scalability and smaller block sizes so that it can do its purpose of being gold in the form of crypto and nothing else.
  5. What is a Turing Complete programming language?
    A turing complete programming language is a language that can solve any complex solution you can think of. Meaning you can program a turing complete language theoretically to do literally anything that you want it to do. It can also execute loops which non turing complete languages cannot do due to changing variables in the loop that need to be adapted after each loop.

  1. Evm containes The instructions on a program. It also executes The instructions in all nodes in The blockchain by telling The cpu go execute

  2. Evm can read bite code, IF it is programmet in solidity.

  3. you program in solidity the its compailed into bite cod.

  4. Because its not turing complete.

  5. Its a programminglanguage that in theory makes it possible to program anything, in reality this isn’t always true because of scalabilty , cost , etc.

  1. What does the EVM do?

EVM allows code to be executed across the Eth network in such a way that all the nodes are in consensus (agreement) about what the result should be.

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

The instructions within a smart contract that the EVM can read are formatted in Bytecode.

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

Solidity is the, or a native programming language for Ethereum smart contracts. Once the code is written in Solidity, it is run through a compiler and output as Bytecode. So I guess, Bytecode is a sort of child to the parent Solidity.

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

It’s not Turing complete, by design.

  1. What is a Turing Complete programming language?

It’s a language that, in theory is as vast as the imagination, in its breadth and scope. It’s meant to be able to solve any and all issues that may arise from its use. In practice however, it’s still limited by usability, time and money… and Eth’s scalability issues.
