Homework on EVM

Ethereum 101
#1264
  1. EVM is an intermediary between the CPU and smart contacts, which provides security and a way to put a more complex program on top
  2. Byte code
  3. We use solidity to program the smart contact and then the compiler turns this into byte code for the EVM to read
  4. Script language of BTC isn’t Turing complete, can’t run loops
  5. JavaScript, it can run any

@martin-vienna well, To clarify It is a compiler that connects Solidity and bytecode.

Happy learning :grinning:,

1.- EVM = Etherium virtual machine is a smart contract that runs in all computers over the network
2.-bytecode
3.-solidity is a program language with a compiler that transforms the information into bytecode
4.-Bitcoin is not Turing complete, it runs on script language while Etherium is Turing complete and runs on bytecode
5.-Turing complete language code is bytecode

So its more similar to english would be more percise I guess? :smiley:

Anyway, I dont have experience yet in any programming langugage other than basic html

1.)
EVM Execution Model:
A Turing-complete virtual machine that enables execution of code exactly as intended.
It is the runtime environment for every smart contract.
Every Etherium node runs on the EVM to maintain consensus across the blockchain.

2.)
EVM Bytecode

3.)
-First you use a programming language (Solidity) to whrite the smart contract .
-After that you use a compiler to translate this language into a another programming language (Bytecode).
-The contract is now readable for the EVM.

4.)
The programming language of bitcoin is not turing complete, therefore the possibilities are very limited.

5.)
A "turing complete language”, which means everything that needs to be computed can be computed using it.

  1. Ethereum Virtual Machine executes smart contracts and translates them to byte code to CPU.

  2. EVM can read instructions written in Solidity or Viper code.

  3. EVM decodes Solidity instructions to execute them in Bytecode.

  4. Bitcoin can’t run the same type of complex programs like Ethereum because its programming language Script is not advanced enough or not a Turing Complete language.

  5. Turing Complete is a self sufficient ability of a programming language to actively change the state of the computing system.

#1 EVM reads smart contracts using computer hardware cpu, evm is used as a program to read all code that solidity inputs

#2 new rules byte code

#3 all nodes re checking for validation

#4bitcoin using script limited programing ,ethereum on other hand is dynamic

#5 turing complete program language is not limited like bitcoin scripts

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

Quite close sir(s), but the format of the instructions that EVM read is ByteCode.

If you have any more questions, please let us know so we can help you! :slight_smile:

  1. What does the EVM do?

Ethereum Virtual Machine actions a smart contract (Execute code on the network). All EVMs across all nodes need to execute the smart contract. If they all get the same result, consensus has been reached. Once consensus has been reached the CPU of the node actions the smart contract.

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

EVM reads the Bytecode.

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

The smart contract is written in solidity and this is converted to ByteCode using a compiler. Ethereum is writing a new language called viper which will also likely need to be compiled into Bytecode.

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

Bitcoin uses a non Turing language which means it can not solve all programs that it may need to solve.

  1. What is a Turing Complete programming language?

A turing complete programming language means that you can in theory programme anything you want. Turing complete also allows you to program loops.

1.What does the EVM do?

Read and and tell the CPU to execute instructions inside the smart contract.

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

EVM bytecode

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

A smart contract is written in Solidity, a compiler translate Solidity to bytecode and the EVM can read it the instructions.

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

They have a programming language called script, and its not turing complete, which means the program language has limited.

5.What is a Turing Complete programming language?

A program language is considered to be turing complete as you can calculate all calculable problem in it, solidity is a turing complete programming language you can program anything you want.

  1. EVM isolates the smart contract from the CPU.

  2. The format is byte code

  3. Solidity is language used to program the SC, then compiles (translates) it to bytocode so the blockchain understands it.

  4. Bitcoin cannot solve all mathemathical operations, so it is not Turing Complete. Ethereum in the other hand, can execute all sorts of commands and instructions.

  5. Turing Complete means it can run any mathematical function.

  1. The Ethereum Virtual Machine (EVM) executes programs on all nodes of the network. It acts as an intermediary between the network and the CPU of each node’s computer.

  2. EVM reads Ethereum byte code.

  3. Code written in Solidity is compiled into Ethereum byte code. The EVM will read this byte code and then tell the CPU what to do. The code is not executed by the CPU itself in case the code contains malicious activity. Then the code could be run on all nodes, taking over these computers and the entire Ethereum network, not to mention causing a whole heap of other problems.

  4. Bitcoin cannot run complex programs like Ethereum can because Bitcoin is not Turing Complete (TC).

  5. A Turing Complete programming language can understand any code and execute any programs given enough memory, simulating a Turing machine theorized the eponymous Alan Turing. Bitcoin was intentionally designed to be not Turing Complete to prevent spam and keep the blockchain size down.

What does the EVM do?
A: EVM is a virtual stack running on every node in the network and is responsible for agreeing upon and executing the bytecode of the smart contract.
What is the format of the instructions that the EVM can read?
A: EVM’s read bytecode
What is the relationship between the programming language Solidity and Bytecode?
A: Solidity is a the programming language used to create the smart contracts. A compiler is then used to convert the Solidity program into bytecode, thus allowing the EVM to read and execute the code.
Why can’t Bitcoin run the same type of complex programs like Ethereum can?
A: Bitcoin uses Script, a non-Turing complete language, thereby limiting it’s uses past the basic.
What is a Turing Complete programming language?
A: A programming language that can solve all computational problems needed to execute smart contracts and/or other directives that, as a comparison, Bitcoin’s Script can not perform. Ex. Solidity, C++. Javascript, etc…

  1. Evm makes it so it is possible to execute code on the Ethereum network so there is consensus.
  2. EVM runs from solidity software to EVM byte code
  3. bytecode runs on solidity software
  4. Bitcoin can not run the same type of complex programs because its language is not turing complete.
    5 Turing complete is a language that tells programer to tell software to do one thing several times.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? it’s not a Turing Complete Programming Language.
  5. What is a Turing Complete programming language? A language that allows any functions imaginable to be created as well as looped, thus allowing for smart functions in smart contracts.

  1. The EVM is a code that reads a smart contract from different nodes and tries to find results in it.
  2. The EVM reads byte code which is generated from a programming language such as Solidity.
  3. As i stated Bytecode looks at Solidity and transforms the programming language into a version that the EVM can read.
  4. Because bitcoin uses a 1.0 script programming language and Ethereum uses a 2.0 programming language.
  5. A turing complete language means that there’s no limit to what you can program really. The sky is the limit!
