Homework on EVM

Ethereum 101
#301

  1. EVM stands for Ethereum Virtual Machine, every nodes runs the EVM it verifies transactions, and executes smart contracts.

  2. EVM reads byte codes, it doesn’t matter what language you use (solidity or viper) it will use a compiler and read the byte codes.

  3. Ethereum language is Solidity, however it uses a compiler to make it to a byte code so the network can read it.

  4. Solidity is Turing Complete, meaning it can solve basically any problem. However Bitcoin script isn’t Turing Complete and can only create vary basic, primitive programs.

  5. A Turing Complete language means it can solve all problems, and can do infinite numbers of possible programs.

  • What does the EVM do?

The Ethereum Virtual Machine (EVM) is the interface which can run the script for Smart Contracts.

  • What is the format of the instructions that the EVM can read?

The format that the EVM can read is called ‘Bytecode’.

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

*Solidity is a programing language that is much more comprehensive for programers to use, Bytecode is the language that the EVM can understand. Solidity can be compiled into Bytecode, allowing programers to develop their SC for the EVM

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

Unfortanetly Bitcoin cannot run the same programs as Ethereum because the language that BTC uses, Script, is not Turing Complete. Script is a simple language with only a few programming features.

  • What is a Turing Complete programming language?

A Turing Complete language has the ability to run ‘loops’ with its programs. Allowing for certain aspects of the code to be autonomous.

In ETH using the truly complete programming language called solidity, that means you can do whatever you want to do with this language.

#306
  1. An EVM is capable of reading the instruction of a SMART CONTRACT in a computer and give the CPU of that computer those instructions. The reason why we do not ask CPU to do it directly is because of security.
  2. The format is EVM bytecode
  3. Solidity is a programming language where you can programm you contract. It has a compiler which translate the logic and the instructions into bytecode.
  4. Bitcoin is not build to execute smart contract but to make transactions. It runs very simple scritp and it is considering a TURING INCOMPLETE LANGUAGE, while Ethereum is a TC complete language, where you can basically do what you want.
  5. A TC language is a program that can do any tipe of calculation.
    TURING COMPLETE LANGUAGE = machine that, given enough time and memory along with the necessary instructions, can solve any computational problem, no matter how complex. Ex.: modern programming languages as most of them are Turing Complete C++, Python, JavaScript, etc…

Answers

  1. EVM (ethereum virtual machine) allows you to execute code/contracts on the ethereum network so all (nodes) are in consensus as to what the results should be. It is a piece of code that runs on top of existing hardware of existing nodes in the Ethereum network. It is an application that executes smart contracts. It looks at all the instructions of the smart contract then gives the instructions to the CPU to execute. then gets a result. All nodes will do the same and then reach consensus. EVM ensures nothing malicious happens. EVM contains the smart contract within itself so as to not allow it to take over the CPU.

  2. The format EVM reads is in bytecode.

  3. The relationship between solidity and bytecode is that solidity is a language that is put through an application that compiles/translates it into bytecode which EVM then reads and instructs CPU to preform.

  4. Bitcoin cannot run the same type of complex programs as ethereum because the scripting language that runs bitcoin is not turing complete.

  5. Turing complete programming language is a language that can program anything you want in theory. It can have loops. Where a non truing complete program is much more limited.

#312
  1. EVM has the access to smart contract, reads byte code to execute what is in smart contract.
  2. The format of CPU would execute instructions on smart contract.
  3. Did not get that info.
  4. Because its not turing complete.
  5. It works in loops, it can do same function multiple times.
#313

  1. The Ethereum Virtual Machine is what communicates to each Ethereum node the code deployed on the network. It is an application that runs on every node of the Ethereum network, and runs all code deployed on the Ethereum network, acting as the middle-man between the Ethereum network and the resources of every node on the network, preventing direct access to any node’s resources, such as the CPU or other hardware.

  2. The EVM runs Bytecode, which can be complied from one of Ethereum’s programming languages.

  3. Smart contracts that are written in Solidity need to be compiled into Bytecode before the EVM can execute the code.

  4. Bitcoin is intentionally Turing incomplete, in contrast to Ethereum, which is why BTC cannot run some of the complex programs ETH can.

  5. A Turing complete programming language can execute any arithmetic or logical operation, theoretically allowing any imaginable process to be executed.

#314
  1. What does the EVM do?

Ethereal Virtual Machine is a program that every node runs on it’s CPU, in order to execute smart Contracts. The main reason why the EVM is used as an intermediary is to protect the network from any malleability that could control the network as a result for example.
2. What is the format of the instructions that the EVM can read?
The EVM reads in Bytecode.
3. What is the relationship between the programming language Solidity and Bytecode?
To program a smart contract we can use Solidity that almost looks like English, but as the smart contract needs to be written in Bytecode, for the EVM to read it, the Solidity written code is compiled to Bytecode.

  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    It’s not the aim of bitcoin, bitcoin is a currency/ digital gold depending on your opinion or the value you attribute to it, and it’s language (script) is not turing complete, as such it can’t get spammed. Because as we all know, that would give extra scalability issues.

  2. What is a Turing Complete programming language?

A Turing (enigma code developper) Complete Programming Language is a language that can execute complex problems. A special feature is that it can include loops. That means that you can run the program several times over again.

#315
  1. The EVM (Ethereum Virtual Machine) reads and executes instructions of a smart contract.
  2. The EVM will read a Bytecode format.
  3. Solidity is the programming language to design smart contracts. As the EVM can only understand Bytcode to execute instructions, the Solidity code will get through a compiler (sort of code converting app) so that the EVM can run successfully.
  4. Bitcoin programming language can only execute simple transaction tasks since digital money is Bitcoin’s only mainspring. Smart contracts on the other hand require a higher level of technicity. It is not only about money transactions. It is also and foremost about money handling and transaction automation when specific conditions are respected.
  5. A Turing Complete programming language can solve every kind of complex problems (in theory).
#316

Hello ! I have a question concerning solving complex problems and Turing Complete programming languages. Ever since SegWit was implemented, it enabled the development of more complex features like second-layer protocols used in the lightning network and MAST used for bitcoin smart contracts. So Bitcoin did catch up quite a bit with more sophisticated features. So technically speaking the gap between Bitcoin and Ethereum is not as big as it used to be, right ?

#317

  1. EVM is a piece of code, an application that is running on top of the existing hardware of each node in the Ethereum network, that uses all the resources that the nodes have and can also read and execute smart contracts.

  2. EVM reads Bytecode.

  3. Smart contracts are written in solidity, which compiles into Bytecode, a language that EVM understands.

  4. Because Bitcoin’s program language (script) is very limited, basically it is not Turing Complete like Ethereum’s (solidity) which is a Turing Complete language.

  5. Theoretically, with Turing Complete language we can program anything we want (like loops), anything we can think of, but in practice it is still limited in terms of scalability and what is practically usable.
