  1. EVM is an ethereum virtual machine and it executes code on the ethereum blockchain.
  2. EVM can only read bytecode.
  3. Solidity is a high-level programming language like JavaScript. Computers are not able to read high-level languages therefore solidity code needs to be compiled into bytecode that computers can understand.
  4. Bitcoin cant run smart contracts because its scripting language is limited by design. The bitcoin script is not Turing complete. For example, it does not have loops.
  5. Turing complete programming language is a language that can in theory solve any programmable problem.

  1. What does the EVM do?
    The EVM reads byte code (compiled from Solidity or Viper) and instructs the CPU to take actions according to the code.
  2. What is the format of the instructions that the EVM can read? Cyte code, but EVM can compile Solidity and Viper into byte code.
  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the programming language used by developers, but byte code is what is actually read and understood by EVM.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin was supposed to be just digital gold and internet currency. Having smart contracts run on the blockchain may congest it, slow transactions and increase block size too much. Bitcoin devs were afraid the blockchain may be “spammed” by too many trasactions created.
  5. What is a Turing Complete programming language? Turing complete means the programming language can create anything you can think of and includes loops as functions that non turing complete programming languages do not have.

  1. What does the EVM do?

An EVM allows it to be possible to have a process of having a smart contract running in a decentralized way on the blockchain enabling consensus to be reached.

The EVM is there mainly for security reasons by ensuring nothing malicious happens when executing a smart contract, by being in the middle of the smart contract and the Ethereum nodes CPU.

This is done because anybody can deploy any smart contract on the Ethereum network and it might have some malicious instructions in order to take advantage of the Ethereum computer node by using the CPU directly. If a smart contract could break free from the EVM and start giving commands directly to the CPU it would be very bad resulting in the entire network being vulnerable.

An EVM is also there to execute all instructions within a smart contract and get to a final result at the end of the instructions within the contract which all EVMs on each computer node has to do the same executing each instruction to reach the same result in order to achieve consensus.

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

The Smart contract will be programmed using solidity or viper which will then be compiled into Byte-code which is the format needed by the EVM to be able to read and execute all instructions within the smart contract. The EVM doesn’t care about which programming language was used, its only concerned for the byte-code it receives which allows it to execute the smart contract instruction by instruction.

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

Solidity is a programing language like java script which is used to program smart contracts into byte-code by using a compiler that takes the solidity code that looks like English, compiling all of the logic and instructions into byte-code allowing the EVM working in conjunction with the CPU to be able to execute the smart contracts instructions.

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

Bitcoin is not Turing complete so it cannot solve all of the problems that it might have to solve and if you wanted to program some sort of application it would be very limited due to the programing language bitcoin uses which is called scripts, which is a simple version of smart contracts but not really a smart contract due to being very primitive. You could program a multi sig wallet as an example using bitcoin scripts unlike the complex smart contracts’ solidity can create by being a Turing complete program.

  1. What is a Turing Complete programming language?

Solidity in Ethereum is a Turing complete programing language allowing you to program anything you want or could think of in theory at the same time being a little hindered on practicality though due to Ethereum still having scalability issues. On a technical level a Turing complete language will have something called loops which is a feature of a programming language that allows you to tell software to do one thing several times which is very important in some cases because without loops you would have to physically write all instructions by hand which in some instances cannot be done because a variable might change and you need to be able to adapt the looping to a changed state in your smart contract which means that many features cannot be done without loops which can only be found in a Turing complete language.

  1. EVM stands for Ethereum Virtual Machine and executes code that is input via programs, or smart contracts.
  2. EVM reads byte code (i.e., code that has been complied from another language such as Solidity or Vyper).
  3. Solidity is a high-level language that is digestible by programmers. This code is then compiled into bytecode that can be digested by EVM.
  4. Bitcoin can’t run the same types of programs as Ethereum because it is not Turing complete and can’t perform some key operations such as “loops”.
  5. Turing completeness means that a program is able to run all types of computations and instructions (i.e., there are no limits to the types of computations it can execute).

  1. What does the EVM do? It executes code and allows developers/coders to formulate Dapps.

  2. What is the format of the instructions that the EVM can read? Bytecode compiled in the user’s CPU.

  3. What is the relationship between the programming language Solidity and Bytecode? Solidity is a Turing-complete programming language coders/developer use to create smart contracts. A compiler translates Solidity to Bytecode and can be run back/forth by the individual user’s CPU and the EVM.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? Because Bitcoin’s Script programming language is not a Turing-complete language. It simply cannot process/solve at the level of complexity that a Turing-complete language can. In essence, Bitcoin is simply designed to be digital gold without the ability to dynamically scale its function in a complex manner (e.g., set conditions precedent for triggering contract performance).

  5. What is a Turing Complete programming language? A language that can solve complex problems. It allows, at least theoretically, a programmer to program anything the programmer elects to create. As a specific example, a Turing-complete language can perform loops, where as a Turing incomplete language typically cannot.

An EVM reads the bytecode based on the compiler of Solidity / Viper.

Bytecode

Solidity is one of the programming languages used where logic and instructions are compiled to the Bytecode which the EVM reads.

Bitcoin’s programming language is not Turing Complete while the Ethereum programming langauge is Turing Complete.

A Turing Complete programming language is a programming language where all problems provided to the program are solvable which is essential for Smart Contracts and makes the use-case amazinglzy broad.

  1. the Ethereum Virtual Machine is an interface between the ethereum programming language (e.g. solidity, viper) and the node’s computing resources on which it runs (so that the node’s resources are isolated to some degree from the blockchain)

  2. the EVM reads bytecode (which i understand to be compiled solidity/viper instructions that are specific to the device being used)

  3. solidity is the programming language, instructions from which get compiled into bytecode for the EVM to run at a machine level

  4. Bitcoin’s programming language, “script”, is not turing complete, e.g. it lacks loops; solidity IS turing complete and thus more powerful.

  5. Turing completeness is the idea that a machine can calculate any algorithm, according to wikipedia… i believe it.
