[TomA]

1. What does the EVM do?
   Is a virtual machine that Executes smart contracts (small programs) on the Ethereum network.
2. What is the format of the instructions that the EVM can read?
   Byte Code (Machine language) so the local CPU can execute the code.
3. What is the relationship between the programming language Solidity and Bytecode?
   It is Solidity programming language is changed into Byte Code (Machine language) by a compiler so the local CPU can execute the code.
4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Because the script language that Bitcoin uses is not Turing Complete. No Loops allowed.
5. What is a Turing Complete programming language?
   A programming language that allows for complex computer operations to take place. Looping, IF’s etc.

[EndGame]

1. The EVM processes smart contracts and provides security for the node CPUs.
2. EVM instructions are written in Bytecode.
3. Solidity is the developer programming language which is then compiled into Bytecode for EVM use.
4. Solidity is a Turing Complete language so it can run loops and complex functions. Bitcoin’s Script is not turing complete so it’s functionality is limited.
5. A Turing Complete programming language is capable of performing all of the basic decisions/conditional statements and loops.

[SkillTulli]

1. An EVM is a Virtual machine built on Ethereum that works on top of the hardware of all Ethereum nodes and allows these nodes’ CPUs to read and execute programs and smart contracts.

2. It’s called EVM byte code and it derives from Solidity’s programming language compiler.

3. Solidity is the programming language, the byte code is what the EVM reads in the program. The byte code derives from Solidity’s compiler.

4. Bitcoin’s programming language (Script) is not Turing complete like Ethereum’s.

5. A programming language that has solution to more problems because it contains extra features like Loops.

[ZachGMiller]

1. The EVM is software that reads smart contracts and tells the CPU to execute things.
2. byte code
3. Solidity is the programming language developers use. They convert it to byte code and byte code goes into the smart contract which is then sent to the EVM.
4. Bitcoin uses the programming language script which is much more limited. Script coding language is not Turing Complete.
5. Turing Complete code languages allow the developer to make much more complicated/advanced contracts. They allow for loops.

[Kamil37]

1. Etherium Virtual Machine reads smart contract and communicate with CPU
2. It is byte code
3. In order to write bite code programmers using programming language called Solidity and than complier compile the language to byte code and than EVM can read all the instructions in byte code.
4. Because bitcoin programming language is limited only to simple contracts like multiple signatures
5. Turing Complete programming language means that this system is able to recognize or decide other data-manipulation rule sets.

2. It reads Bytecod
3. You program in solidity that then interacts with bytecod which then execute the instruction.
   4.It is not running a Turing complete language
4. A programming language that enables you in theory to cod everything you can think of.

[mangold]

1. What does EVM do?
   Reads the smart contracts and orders the cpu to execute it
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 language people use to code on Ethereum and it gets translated to bytecode so the EVM can read it.
4. Why cant bitcoin run the same type of complex programs like Ethereum can? Because bitcoins language script is not turing complete which means it cant be programmed to do whatever you want, its capability is limited.
5. What is a turing complete programming language?
   A language which you can use to code what ever you want.

[Furby]

1. What does the EVM do?

• It reads and executes the smart contracts into byte code. This is then forwarded to be read by the CPU. Each node in the network has an EVM and does the same process to reach consensus. It works as a piece between the smart contract and the cpu.

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 code is compiled into byte code using a compiler, which is then used to run through EVM and eventually to CPU.

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

• Because it’s programming language Script is not turing complete.

5. What is a Turing Complete programming language?

• Basically a programming language that you can program anything you want on it, such as adding loops into a smart contract etc.

[Michael_McNeil]

Answers:

1. EVM is an application that exists on all computers within the Ethereum network. Its job is to directly interact and execute the instructions contained within a smart contract. This means the EVM is a buffer between the resources (i.e. CPU etc.) of a particular network computer and the smart contract. This buffer function also provides a layer of security by containing the smart contact from the computer/CPU to ensure no malicious code is run on the computer. The EVM existing across all network computers is also crucial for consensus to be achieved with respect to the validity of a particular smart contract;
2. The format of the instruction read by EVM will be in EVM Bytecode;
   3 Smart contracts are generally written in Solidity but compiled/converted into EVM Bytecode, which is used by EVM to execute the instructions of the smart contract;
3. Bitcoin can’t run the same type of complex programs like Ethereum can because Bitcoin code is written in Script which is not a Turing Complete Programming Language;
4. A Turing Complete Programming Language is a language that can process “loops” or iterations of code, which allow you to theoretically program anything you want.

• What is a Turing Complete programming language?

1. The main thing that the EVN does, is ensuring that nothing malicious will break loose from the smart contract and harm the Etherium node or the entire Etheriam network.

2. The EVM can read smart contacts.

3. The solidity programming language knows how to compile smart contacts into Bytecode.

4. The Bitcoin network can not run the same complex programs as Etherium because it is not turning complete.

5. A Turing Complete programming language is a language in which everything can be programmed. Whatever comes in the mind of a programmer can be programmable with a Turing Complete programming language.

[zoefleischer]

1.What does the EVM do?
An EVM is an application running on top of the computer‘s hardware, reading smart contract instructions and making the CPU execute them

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 in which the instructions are written, it has a compiler that turns these instructions into Bytecode for the EVM to read. The EVM doesn‘t care which programming language is used, because the compiler will always translate it into Bytecode.

4.Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Because Script, Bitcoin‘s programming language is Turing incomplete.

5.What is a Turing Complete programming language?
A language that has no limitations in what you can program with it and also contains specifics features like loops.

[Randallcrum]

1. EVM runs smart contracts, acting as a buffer between the smart contract and the CPU of a machine in the Ethereum network, making it possible to run small programs on the blockchain.

2. Ethereum Byte Code.

3. Solidity is a programming language used to write programs for the EVM, which are then compiled into Bytecode which the EVM can read.

4. The programming language for Bitcoin, Script, is very basic and isn’t intended to do complex smart contracts. Bitcoin development team has chosen to restrict this feature in order to keep block sizes small and focus on a single purpose for Bitcoin; digital currency.

5. Turing Complete means that in theory a programming language can be used to write practically any program you can imagine. As an example, Solidity is able to include loops, which are excluded from Script in order to prevent cluttering the blockchain of Bitcoin.

[Jill_Brewer]

1. EVM reads instructions from the smart contract and sends it to the CPU for execution
2. EVM reads Byte Code.
3. Solidity is the programming language for the Ethereum blockchain, and Byte Code is the language for the smart contract instructions.
4. Bitcoin has their own Script which is very simple. Unlike Ethereum’s Solidity, Script cannot solve problems or operate in a dynamic way. Bitcoin also does not want to increase the size of the blockchain with potential loops, spam, etc.
5. Turing Complete programming language can solve all problems and can be programmed to do anything.

[samjlunt]

1. What does the EVM do?
   Ethereum Virtual Machine is what is used to execute smart contracts that have been coded. EVM’s are powered by nodes across the whole Ethereum blockchain.

2. What is the format of the instructions that the EVM can read?
   EVM reads Bytecode. Initially the code can be written in Solidity or Viper which is then converted to Bytecode for the EVM.

3. What is the relationship between the programming language Solidity and Bytecode?
   Initially the code can be written in Solidity or Viper which is then converted to Bytecode for the EVM.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Bitcoin can run some programs up to a certain point but it is very limited in it’s capabilities. It doesn’t have a large scalability scope. Initially Vitalek wanted to build on Bitcoin but realised the limitations so created Ethereum.

5. What is a Turing Complete programming language?
   It has the ability to be completely programmable without limitations. In theory nothing is impossible in terms of what you can build on the Ethereum blockchain. There are some nuances but scalability should not be an issue.

[jornack]

1. What does the EVM do?
   It provides a secure isolated virtual environment that runs on an Etherium node and executes smart contracts.

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?
   Solidity is a programming language that is compiled into EVM Bytecode.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Bitcoin only supports the Script language which is not Turing-complete. This makes it limited in it’s utility in terms of Smart Contracts.

5. What is a Turing Complete programming language?
   It can solve all mathematical problems.

[elconocrypto]

1. EVM is a virtual machine running in the Ethereum network which will read and execute smart contracts. It ensures security and consensus on the entire ethreum network.

2. The EVM reads ByteCodes

3. Solidity is the program languaje used to write the smart codes but then its compiled and translated into bytecode. EMV reads the bytecode.

4. Bitcoin language is writting in script language and the program languaje is “Not Touring Complete” Languaje. Which means it is limited to resolve certain problems.

5. A “Touring Complete Languaje” ables to program and run complex program. It can resolve any problem. It is unlimited. It’s able to do loops.
