  1. What does the EVM do?
  • EVM reads and executes all of the instructions inside of the smart contract.
  1. What is the format of the instructions that the EVM can read?
  • EVM can only read in bytecode.
  1. What is the relationship between the programming language Solidity and Bytecode?
  • Solidity is a programming language that many programmers use to write the instructions in and then they use a compiler to compile it into bytecode.
  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
  • Bitcoin uses script programming language which is not turing complete, and if the programming language is not turing complete it means that it can not run complex programs like those on Ethereum.
  1. What is a Turing Complete programming language?
  • It means that this language allows us to programm whatever we want with no limitations … (In theory)

  • What does the EVM do?
    The EVM reads the smart contract and communicates the information to your CPU after the result is concluded all the nodes need to reach a consensus.
  • What is the format of the instructions that the EVM can read?
    The format is EVM Bytecode.
  • What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the language where the contract is written in, and inside the solidity application you have a compiler that compiles everything in to Bytecode.
  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because bitcoin is written in Script and that is not a Turing complete programming language.
  • What is a Turing Complete programming language?
    A Turing complete programming language allows you to program whatever you want without limitations.

  1. EVM executes smart contracts, which is running on the all notes.

  2. Virtual machines are essentially creating a level of abstraction between the executing code and the executing machine. This way to improve the portability of software, as well as to make sure applications are separated from each other, and separated from their host. EVM running in the sandbox environment which means it is isolated and has no direct link to a centralised CPU.

  3. When we compile the solidity code using the compiler, it will translate our code into bytecode, something only the EVM can understand.

  4. The deference between Ethereum and Bitcoin is that Bitcoin is only a currency, where Ethereum is a ledger technology that companies are using to build new programs. Bitcoin is version 1.0 and Ethereum is 2.0. Bitcoin use only script where Ethereum EVM smart contract can also use Loops.

  5. A Turing Complete system means a system in which a program can be written that will find an answer. Also that means in principle it could be used to solve any computation problem. Solidity is Turing complete language.

  1. The EVM (Ethereum Virtual Machine) reads and executes the instructions of smart contracts.

  2. EVMs work with Bytecode, which decouples it from specific environments or even programming languages.

  3. The Bytecode which the EVM can read is produced by a compiler. The compiler takes a program written in Solidity and outputs the respective Bytecode.

  4. The Bitcoin scripting language is not Turing complete.

  5. A Turing Complete programming language is capable of solving any computable problem.

1. What does the EVM do?
EVM stands for Etherium Virtual Machine. It reads and executes smart contracts in Etherium nodes. Also, it acts as a buffer/additional security between the smart contract and CPU. Without EVM, the smart contract could access the CPU directly.

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

3. What is the relationship between the programming language Solidity and Bytecode?
Solidity is the programming language (or viper) used to program. It then is converted to Bytecode.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Bitcoin uses a programming language called script and it is not turing complete.

5. What is a Turing Complete programming language?
It is a programming language that has less limitations. For instance you can program loops, or give directions how to execute commands.

  1. EVM: Ethereum virtual machine. It runs on the network of computers that make up the Ethereum blockchain. It reads and executes the smart contracts that are propagated through the network .

  2. It can read turning complete programs written on Solidity and other languages like Viper once translated into Bytecode mode.

  3. All instructions written on Script need to be compiled and translated into Bytecode. The EVM ultimately reads and executes what has been translated to Bytecode.

  4. Bitcoin is written in Script which is a simple and basic non turing complete program.

  5. A language that can perform complex mathematical operations. In other words, almost anything is theoretically programmable in a turing complete program.

  1. What does the EVM do?
    EVM is an acronym for 'Ethereum Virtual Machine. … The Ethereum blockchain is widely regarded as being the first blockchain system that has a team dedicated to its development and maintaining its well-being. According to its website, Ethereum is a decentralized platform that primarily deals with running smart contracts.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity exists for the EVM to execute instructions, a smart contract is in bytecode and therefore programmers are using Solidity to compile their messages into bytecode-language that the EVM understands and can execute commands from.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin cannot run the same complex smart contracts in the way that Ethereum can, as it uses Script, which is non-Turing complete language.

  5. What is a Turing Complete programming language?
    A turing Complete language can do one thing several times (create loops)

1- Read and execute the smart contracts then gives instructions to the CPU, ensures
that it’s imposible to execute code directly from the smart contract.
2- Bytecode
3- Solidity is the programming language we use to establish the smart contract, so we write a set of instructions that the compiler will change to bytecode format so the EVM can read it.
4- Because it uses an not complete turing programming language so it cannot do things like loops.
5- It’s a system of data-manipulation rules

  4. Porqué BItcoin no puede correr el mismo tipo de complejidad en programas como lo hace Ethereum?
  5. Qué es un lenguaje de programación Turing Completo?

1- Lee y ejecuta los contratos inteligentes y entonces manda instrucciones al CPU,
asegura que sea imposible ejecutar código directamente desde el contrato sin
pasar antes por la EVM.
2- Bytecode.
3- Solidity es el lenguaje de programación que usamos para establecer los contratos
inteligentes, así que escribimos el conjunto de intrucciones para que después el
compilador las cambie de formato a bytecode entonces la EVM los pueda leer.
4- Porque bitcoin utliza un lenguaje de programación que que no es Turing
Completo por lo que no puede hacer iteraciones, necesarias para los contratos.
5- Es un sistema de reglas de manipulación de datos.

  1. What does the EVM do?

EVM is virtual intermediary between smart contracts and physical hardware. It reads smart contracts and then instructs hardware to execute the contract code. It is needed to to keep malicious code in smart contracts from taking control of hardware and overcoming nodes or the Ethereum network as a whole.

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

The format of the instructions that EVM reads is byte code.

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

Solidity is the actual code language that is used to write smart contracts on the Ethereum network. Solidity contains a compiler that translates solidity code into byte code. Byte code is the code that is then entered into the smart contract and read by the EVM.

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

Bitcoin is written in script, which is not Turing Complete. It is limited in what it can actually execute.
Ethereum is written in solidity, which is a Turing Complete programming language. It gives Ethereum the capability to theoretically do anything with a smart contract.

  1. What is a Turing Complete programming language?

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

The actual code language is solidity. That is used to write smart contracts on the Ethereum network. Solidity contains a compiler which translates solidity code into byte code. Byte code is read by the EVM when the code has entered into the smart contract.

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

Bitcoin uses a NTP, a Non Turing Programming language (it is written in script). It is therefore limited in what it can actually execute. Ethereum is instead written in solidity = Turing Complete programming language. With that Eth. is capable to theoretically do anything with a smart contract.

What is a Turing Complete programming language?

A TCP language is a language that can solve any problem (no limitations). With that it is possible to write code to solve any problem.
