Homework on EVM

[Niieells]

1. Ethereum virtual machine executes smart contracts on each note of the Ethereum blockchain.
2. EVM reads byte code.
3. Smart contracts are written is solidity then the compiler turns it to bytecode and EVM reads the bytecode.
4. Because the script is not a turing complete language.
5. Turing complete language is where you can put anything in a smart contract.

[Brijay]

1.EVM executes the code on the smart contracts on Ethereum, allows smart contracts to interact with each other and provides a layer of security between the smart contracts and the nodes.

2.The format of the instructions that the EVM can read is Bytecode (also called portable code or p-code).

3.The relationship between the programming language Solidarity and Bytecode is; Solidarity is a human-readable computer language that is used to write the smart contracts - this is then converted into Bytecode which is the numeric computer language that is understood by the EVM,

4.Bitcoin can’t run the same type of complex programs like Ethereum can because it was decided that Bitcoin was to have only a basic programming language (SCRIPT) so as to avoid possibly malicious complex programs spamming and/or clogging-up the blockchain.

5.Turing Complete programming language is one which implements all the features required to run programs like addition, multiplication, if-else condition, return statements, ways to store/retrieve/erase data etc.

[JustMichael]

1. Read, execute, provide result of Smart Contracts.
2. Bytecode.
3. Solidity a language used to write/create Smart Contracts , Bytecode is the compiled application executed by the EVM.

1. What does the EVM do?

The Ethereum Virtual Machine simulates a native instruction set, and executes byte code on an Ethereum node.

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

The format is Byte Code

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

Solidity is a turing complete human readable programming language that a programmer writes Ethereum programs in. Bytecode is the compiled version of Solidity instructions translated for use by the EVM.

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

Bitcoin’s Script had a different design requiring stability and security over flexibility. It is not turning complete, and goes without loops and other general purpose programming features

5. .What is a Turing Complete programming language?

A Turing Complete programming language is basically any programming language that is capable of the same functionality of a general purpose computer or other Turing Complete Language.

[donhuey]

1.What does the EVM do?

The EVM executes smart contracts on each node through the process of compiling solidity code into byte code that is used to instruct CPU’s on the ethereum blockchain. The EVM also protects nodes from malicious code.

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

ethereum byte code.

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

Solidity is the programming language of the Ethereum blockchain. The EVM takes instructions written in solidity and compiles it into byte code that is readable by a nodes CPU.

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

Bitcoin is not Turing complete.

5.What is a Turing complete programming lang.?

A programming lang. that is able to compute anything.

[iceman007]

   The language includes functions such as loops to perform actions.

[Rzinho]

1. What does the EVM do?
   EVM is at the heart of the Ethereum network and can read and executes 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 is the programming language that is compiled into Bytecode 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 and therefore limited in its scope.

5. What is a Turing Complete programming language?
   It allows for complex programming and includes loops.

[jcampos]

1. EVM is on each node and will be between the smart contract and the CPU will execute the code from the smart contract and will send the instructions to the CPU.
2. EVM can read byte code.
3. Solidity is a layer for programer that make easy to create instructions and these instructions will be compiler to machine code (Bytecode).
4. Because it’s a script that is smaller and also this is only a currency so want to keep this simple to avoid spam on the network.
5. it’s a language where you can write whatever program you want on it.

[Bunbo_Hue]

1. What does the EVM do?

The EVM makes it possible to execute code on the network in a way that the whole network will be in consensus about what the outcome will be. (Ex., paying out your kid if he gets good grades in school)

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

Ethereum reads instructions in byte code.

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

Solidity is the language used to create smart contracts. That solidity code is then ran through a compiler, which takes the instructions and compiles them into byte code.

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

Bitcoin can’t run the same type of complex programs like Ethereum because Bitcoin is NOT Turing Complete, and cannot run scripts such as loops.

5. What is a Turing Complete programming language?

A Turing complete language is a more complex language that’s capable of running loops (and presumably other things?)

[Adrian_P]

1. The EVM reads and executes the instructions of the smart contract and instructing the cpu to execute .

2. Bytecode is the format of the instructions that emv can read.

3 The solidity programming language is compiled into Byte code which can be read and executed by
the EVM.

4. The bitcoin script is not touring complete.

5. The language can solve loops and making repeated task possible.

[PsiMach]

1. What does the EVM do?
   EVMs are virtual machines that run on each node of the Etherium network and can execute smart contracts the results of which will be used to reach consensus on the network

2. What is the format of the instructions that the EVM can read?
   the EVM will execute compiled code or byte code

3. What is the relationship between the programming language Solidity and Bytecode?
   Solidity is a programming language that developers can use to program a smart contract which is compiled to byte code for the EVM to run

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Bitcoin allows a very simple scripting language but it is not a turing complete language like solidity i.e. not all problems can be solved using Bitcoin’s scripting ability

5. What is a Turing Complete programming language?
   a turing complete language allows anything to be programmed i.e. any problem can be solved using it

3.
Solidity is compiled and then transferred to byte code that then runs on the cpu.
4.
Becouse the scripting language of bitcoin is not turning complete.

1. What does the EVM do?
   — EVM is a runtime environment for Ethereum based 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 the programming language. A compiler converts the Solidity code into byte code for execution in EVM.
4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   — Because Bitcoin uses Script language which is primitive and not turing complete
5. What is a Turing Complete programming language?
   — A language that is computational universal and in principle can perform any calculation that any other programmable computer is capable of. A turing complete language is one that can perform any computation given enough resource.

[guillaume_M-D]

I have a bit of a hard time wrapping my head around this topic, the EVM.

Here are some of my questions:

• is it more like a compiler or a cpu.

• the cpu is in the nodes or the miners
  e.g EVM is on or equal to a node
  CPU is on or equal to a miner.

• In which order these elements place their self? And where is the solidity compiler placed.
  Tx transmit > node > evm > miner
  Tx transmit > evm > node > miner
  evm > Tx transmit > node > miner

I have watched a couple of videos also, but most resources give the same definition and I have a hard processing it and putting it in my own word. Maybe I’m not look at it from the right angle and someone can spot it in my questions.

Thank you for any support

[guillaume_M-D]

For what i understand its like the “country customs”. everything that gets in must pass by there.

• It is made to enforce protocol rules and security like eliminate infinite loop.

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

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

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

5. What is a Turing Complete programming language?

1)Evm adds another level of security to gain consensus with the ethereum nodes.

2)Its a piece of code running on the nodes that give instructions to the cpu on what to do.

3)Solidity uses a compiler to write byte code which the evm then reads to carry out instructions.

4)Because it runs on the script language which can’t solve all problems asked of it.

5)Solidity is a turing complete language which can solve all problems asked of it.

[thecil]

1.What does the EVM do?

@RamtiX

… runs Nodes. In his own environment execut smart contracts.

Could you please redesign this answer? the EVM does not runs a node, and does not execute directly any smart contract. (If your confuse with the question, let me know to give you a better understanding)

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

@RamtiX

Smart contracts

Quite close sir, but the EVM does not read/execute smart contracts, they are programmed in Solidity, after that, solidity will compile the smart contract into ByteCode, so the format of the instructions that EVM reads is Bytecode.

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

@RamtiX

byte code is little bits in solidty

Solidity will compile the smart contract into ByteCode

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

@RamtiX

… To Robust
