#2954

  1. What does the EVM do?
    Etherum Virtual Machine (EVM) executes the smart contract.

  2. What is the format of the instructions that the EVM can read?
    Solidity byte code.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the coding language used in the smart contract, however then compiled into byte code for the EVM to execute.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    This is because the code set is turing incomplete, and is only capable to programming “simple” routines, this is by design.

  5. What is a Turing Complete programming language?
    This is a language where in theory you can programme anything you want.

  1. What does the EVM do?

EVM is a piece of code that all computers in the network are running. It executes smart contracts on computers and runs on the top of CPU. IIt reads smart contract instructions and tells the CPU what to do. All nodes need to reach the same results and this how the consensus is made.

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

It is byte code. Programmers use Solidity to read byte code.

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

Compiler takes Solidity code and it will compile logic from Solidity to Byte code and EVM will read all of the instructions.

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

Bitcoin does not have that programality as Ertherum. Script is limited. It is not Turing complete meaning that it cannot solve all problems

  1. What is a Turing Complete programming language?
    Can solve any problem we have and it has loops.

  1. What does the EVM do?

Ethereum Virtual Machine executes the smart contract line by line.

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

It reads Byte code. Typically this is written in Solidity or perhaps Viper.

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

The contract is written in the programme language Solidity. Then, the compiler converts it in to a basic computer language called Byte code.

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

Bitcoin isn’t Turing Complete. The script is limited and not as versatile in it’s programmability. Bitcoin was designed to be simple and not support loops to avoid spam attacks, but however without loops it cannot adjust for variables.

  1. What is a Turing Complete programming language?

It is completely versatile and can allow pretty much anything to be programmed onto it. It supports loops and can be programmed to account for variables.

  2. The EVM reads bytecode

  3. solidity is the language in which smart contracts are created - this is then compiled into bytecode, which runs on the evm

  4. Script, the language that bitcoin uses to run programs, is not turing complete, and is a very simple language without many of the features that solidity has

  5. A turing complete language is one in which all possible mathematical operations can be performed

  1. What does the EVM do?
    EVM is a piece of code which is installed on every single machine / node on Ethereum network to enable the nodes to read and execute the smart contracts.

  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?
    Solidity is a programming language which is compiled by a compiler to Bytecode so that EVM can read the instructions and the logic of the smart contracts written in Solidity

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because the programming language used in Bitcoin network is Script that is not a turing Complete programming language, i.e: cannot program the complicated smart contracts while Solidity, the programming language on Ethereum is.

  5. What is a Turing Complete programming language? It is a programming language that can be used to program anything.

  1. The EVM acts as the global decentralized computer of the Etherium network. It’s function is to act as a security layer between the smart contract and the nodes on the network. All smart contracts are processed within the EVM.

  2. The EVM reads code in bytecode which is compiled from Solidity (or other future compatible languages)

  3. Solidity is the language the contracts are written in Bytecode is the language that EVM reads and executes the contracts in.

  4. Bitcoin was built to be Turing Incomplete, its a feature of Bitcoin that complex smart contracts cannot be written as it’s intended use case is as a currency and store of value. Building a smart-contract compatible language would reduce the security of the system.

  5. A programming language is Turing complete if you can implement any possible algorithm with it.

The EVM is a virtual machine that runs on ethereum.

It can read the programming language particular to ethereums’ programming on the blockchain that they use in its’ virtual machine.

Solidity is a programming language for ethereum while bytecode is one for bitcoin.

It was not set-up to run smart contracts like etherem is.

I think that that program was one in which it was set-up to run loops. It is practical because it would be too complicated and costly to run and write out each line of code one by one.

#2966

  1. What does the EVM do? The EVM reads the instructions in the smart contract executes it and sends to the CPU. This is done on each node of the network until it reaches consensus.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity compiles the logic and instructions down to Bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin has a programing language called script which is not Turing complete. This language has limited capabilities that cannot solve all applications. Bitcoin is meant to be a store of value. If it had a Turing language, the network would be more at risk. For example Bitcoin does not allow loops. Loops would make the Bitcoin network vulnerable to spams.

  5. What is a Turing Complete programming language? A Turing complete language such as Solidity can be used to program anything.

  1. What does the EVM do?

Ethereum is a network of computers where all participants communicate and all have a version of the EVM.
EVM is a software that executes all codes in a trustless system.
These scripts are called smart contracts that allow developers to create Dapps.

Today you have to trust your bank with your money, and trust someone like DropBox with the security of your files and Facebook with your pictures. Ethereum makes it possible to recreate these services as decentralized applications and EVM is what makes it possible. EVM is written in solidity, reads the smart contract in bytecode and gives instruction to the CPU of each node and adds security for the network. .

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

Ethereum bytecode

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

The instructions written in smart contracts are written in bytecodes.
Programmers use solidity programming language, then a compiler, translates the solidity code and instructions compiles it down to bytecodes so the EVM can read and execute these instructions.

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

Bitcoin runs only simple scripts. A simple and limited programming language that is processed from left to right. A not Turing complete language that can’t solve complex problems or actively change the state of the system.

  1. What is a Turing Complete programming language?

A Turing complete language will have loops that can allows programmers to solve any complex problems.
