  • What does the EVM do?
    The EVM is the Etherium Virtual Machine which can execute smart contracts which serves to separate the code from the CPUs of the nodes in the network.

  • What is the format of the instructions that the EVM can read?
    EVM can read instructions from the compiler coming from the Solidity or Viper protocol.

  • What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the programming language used to create the instructions which are translated into Bytecode which is run by the EVM

  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because Bitcoin’s programming language is called Script which is not Turing complete.

  • What is a Turing Complete programming language?
    A turing complete programming language is infinitely programmable through the utility of executing loops.

  1. What does the EVM do?

Ethereum Virtual Machine, runs every compiled byte code of a contract on the network. all EVMs must reach consensus on separate CPUs (done for security)

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

Byte codes

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

Solidity is a language that compiles to byte codes.

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

Because Bitcoin’s programing language “Script” is basic and not Turing Complete.

  1. What is a Turing Complete programming language?

Solidity, Viper
They can use loop functions.

  1. EVM = Ethererum virtual machine translate the smart contract and sends to the CPU for execution .
  2. Evm can read bytecode
  3. Solidity is the programming language used to write the smart contracts then is compiled to bytecode that is executable on the EVM.
  4. Bitcoin is NOT turing complete , Ethereum is turing complete meaning that it can handle a large amount of information and smart contracts with loops etc…
    5.Turing complete language entirely using XML syntax. Moreover, LaTeX, which is mostly used for structuring documents, also contains a Turing complete subset Turing-complete or computationally universal This means that this system is able to recognize or decide other data-manipulation rule sets. Turing completeness is used as a way to express the power of such a data-manipulation rule set. Virtually all programming languages today are Turing-complete. The concept is named after English mathematician and computer scientist Alan Turing

  1. What does the EVM do?

Ethereum Virtual Machine achieves consensus by all the nodes coming to the same result.
The EVM reads the byte code in the smart contract then directs the cpu to execute a instruction, fulfilling a command.

EVM also ensures security by directing instructions to the cpu, not the other way around. This prevents malicious activity from occurring.

  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?

The relationship is the Compiler. This is a special subset application that will take the logic and function of Solidity, and code it into Byte Code.

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

Because of the plausible security risk of loops, which could be used to spam the btc network.

  1. What is a Turing Complete programming language?

This means a coding language that can be used for any application the developer wants, without limits.

  1. Ethereum Virtual Machine is a system that runs on the hardware of the cpu that reads and executes instructions of a smart contract then sends it to the CPU for consensus

  2. it reads in the form of solidity/viper that compiles it into byte code

  3. solidity the smart contract that is first written then translated into byte code so the cpu can run it

  4. bitcoin runs a primitive script that is limited that is not Turing complete that can not solve all problems

  5. solidity is turning complete so you can program anything in loops to repeat any amount of times

  1. What does the EVM do?
    The EVM, Ethereum Virtual Machine, runs smart contract code

  2. What is the format of the instructions that the EVM can read?
    The EVM reads Bytecode, most likely the result of compiling a Solidity program

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is a high level language that can be used to program a smart contract, and bytecode is the output of that program once compiled. The bytecode can be understood by an EVM

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin can run basic code using Script, however the language is not Turing Complete which limits what can be computed.

  5. What is a Turing Complete programming language?
    A Turing Complete language can, in theory, can be used to solve any computational problem

  1. What does the EVM do?
    It allows you to execute code on the ETH network, in such a way we are all under consensus.EVM(Ethereum Virtual Machine) reads and execute smart contracts.
  2. What is the format of the instructions that the EVM can read?
    EVM reads instructions in bytecode.
  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the programming language used to create smart contracts, which are converted to bytecode that will be read by the EVM.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin uses a programming language called Script, which is not turing complete.
  5. What is a Turing Complete programming language?
    Turing Complete suggests that it can solve much more computational program, unlike a non Turing Complete programming language. For example: Bitcoins is non Turing Complete, so Bitcoin can’t be executed under multiple loops and etc.

1/ What does the EVM do ?

EVM= Ethereum Virtual Machine, adds another layer to the process & makes it possible for us all to execute code in such a away that we are all in Consensus for the way it should be.

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

The EVM, will take a look at all the instructions inside the smart contract, do all the calculations ,it will then tell the CPU what to do.

3/ What is the relationship between the programming language Solidity and Bytecode.

Smart Contracts will have lots of bytecodes, so to be able to get at these bytecodes we use Solidity.

4/ Why can´t Bitcoin run the same type of complex programming language ?

Well the Bitcoin language script is not Turing Complete, it can not solve all the problems that would exist, so it is very limited, on the other hand solidity in Ethereum is Turing complete, you can programme anything you want, anything you can think in theory can be done because Ethereum has a limited scalability.

5/ What is Turing complete programming language ?

A Turing Complete programming language will have something called ¨ Loops ¨ its a feature of programming language to tell software what to do.

  1. The EVM is a self contained environment which runs on all of the nodes in the network and can run smart contracts.
  2. The EVM reads smart contracts.
  3. Smart contracts are created with Solidity scripts which have been compiled into Bytecode.
  4. Bitcoin does not allow a Turing complete language to avoid scripts which could be used to spam the network. Basically, this is for security.
  5. Turing complete programming languages can solve any computational problem.
