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?

EVM bytecode is compiled from Solidity.

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

Because Bitcoin is not turing complete while ethereum is.

5. What is a Turing Complete programming language?

It is a programminglanguage in which you basically can program anything you can think of.

[mbthebulldog]

1. Runs the code in Smart Contacts using the CPUs of nodes.
2. EVM reads Ethereum Bytecode, which is written in Solidity (or Viper).
3. Solidity is compiled into Ethereum Bytecode before it is handled by the EVM.
4. Bitcoin developers intentionally excluded a Turing-complete language on their blockchain for security and scalability reasons.
5. A Turing Complete language is one that can perform all actions required of a modern programming language.

[D_V]

1. The EVM executes codes from Ethereum smart contracts.
2. The EVM reads byte code.
3. An Ethereum programming language such as Solidity first has to compile its code into Bytecode, before the EVM can read it.
4. The Bitcoin programming language, Script, is very simple and is not Turing complete.
5. A Turing complete programming language is capable of solving all the problems it might have to solve. One characteristic of Turing complete languages is the ability to execute loops.

[Julia789]

1. What does the EVM do?
   EVM standing for Ethereum Virtual Machine will read the smart contract and tell CPU to execute.

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?
   Bytecode is the language in the smart contract that EVM can read, which is compiled from Solidity.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Because the programming language of Bitcoin is not-turing complete that is very limited.

5. What is a Turing Complete programming language?
   A Turing complete programing language can solve every problems in considerations of time & cost.

[ChadNauman]

1. EVM is able to read the byte code that is encapsulated into a smart contract and talks to the CPU that is on top of in that node.
2. byte code
3. Solidity is what we humans can read and program similar to English, and this is then taken and complied into the byte that the EVM can read.
4. Bitcoin runs on the language Script, and this is not Turing compleet, so it cannot make or complete loops.
5. Turing complete is able to complete loops and the data can also be changed or adjusted with out have to re write new code.

[mkekicks]

1. EVM (Etheruem Virtual Machine) is a global machine maintained by Ethereum nodes, responsible for executing smart contracts.
2. EVM is isolated from environments outside the Ethereum node.
3. Solidity executes the smart contract Bytecode.
4. Bitcoin developers did not want the spam on the network that could lead to overload
5. A Turing complete programming language can execute programmable tasks, unlike a scripting language.

[Michael_B]

1. The EVM acts as a CPU to read and execute smart contracts.

2. The EVM reads instructions in EVM Bytecode.

3. Solidity is the language Ethereum is programmed in. Smart contracts programmed in Solidity are compiled into EVM Bytecode to be processed by the EVM.

4. Bitcoin is written in Script which is not a Turing complete language.

5. A Turing complete language is one that doesn’t have any limitations on what can be programmed with it.

[laudatedeorum]

1, the EVM acts as an intermediary layer between the CPU and smart contracts to send byte code instructions and then write to the CPU. Also EVM is a protective layer between CPU to not allow people to directly write instructions to the CPU.

2. EVM can read the byte code, which in turn is compiled from programming languages such as solidity or viper.

3. Solidity writes the set of instructions and a compiler translates this into byte code.

4. Because its smart contracts are limited and it doesn’t have complete Turing programming, meaning it can’t solve all possible equations and it was only meant for money.

5. Turing complete means any solvable equation can be done in theory, and loops of code can be ordered.

[hamza_khan]

EVM is a compugter software that runs the smart contract in byte code format.

EVM reads instructions in bytecode

Solidity language compiles everything in bytecode which is then executed by EVM.

Bitcoin is not written in the Turing complete language that’s why it can not run program like ethereum.

Turing complete language can do any type of functions that every programming language do.

[Alex_de_Vries]

1. What does the EVM do?
   Ethereum Virtual Machine is blockchain based software program. It allows developers to create decentralized applications. Developers value them because there is no downtime and keeps all objects safe from modifying.
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 a high level programming language. We as developers understand it but the machine doesn’t. When we compile the Solidity code it will translate our code into byte code.
4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Bitcoin is written with Script code. And is not Turing compatible.
5. What is a Turing Complete programming language?
   It means a system in which a program can be written that will find an answer.

[Jaka]

1. EVM reads and executes smart contracts. A version of EVM exists on every node in the network and when a smart contract is executed it is propagated to to every exisiting node and also verified by all of the EVM versions.
2. EVM reads smart contracts complied in Bytecode.
3. Solidity is used to write the code for the smart contracs, the code is then compiled and it can be read by EVMs as Bytecode
4. Bitcoin uses a programming language Script that is limited in its capabilities. It is not a Turin complete language. Ethereum lanaguage is Turing complete thus more capable.
5. Turing complete programming language can solve very complex mathematical equations, tasks and problems

[Max_Rose]

1. The EVM acts as a wrapper that encapsulates the CPU to add a layer of security and interoperability with the CPU, Smart Contract and Nodes.

2. The EVM uses solidity which has been compiled down to read the bytes of the smart contracts.

3. Solidity is the programmable language adopted by Etherium to give instructions to carry out functions thus allowing the bytecode to be read.

4. Bitcoin can not run the same type of complex programs like Etherium can because it is not turing complete.

5. Turing complete language is whereby in theory anything that a developer can think of, he can create by programming complex programmable instructions that can be solved within the smart contract.

[Bridge61]

It has a security funktion between smart contracts and the CPU
Makes it possible that all computers interact with eachother
(It is an application, code on top of the hardware of all pc’s)
small contracts are executed by EVM
all calculations are done by EVM
tells the CPU to execute

[Bridge61]

2. Bytecode
   3.Solidity is a special app used by programmers to get acces to bytecode
   4 5 Bitcoin uses primitive programming by Script, it is not Turing Compeet so you can’t program whatever you want.

[Levi1]

1. EVM is an added layer to ethereum which allows to execute code on a network. EVM is a piece of code that reads the instructions of the smart contracts and tells the CPU what function to carry out. It can read and execute smart contracts.

2.The format of the instructions that EVM can ready is bytecode.
3.Solidity is the programming language used to write and execute the smart contracts in ethereum, where a complier is used for the bytecode. Smart contracts will have many instructions which will be in bytecode and Programmers use Solidity to get to the bytecode.
4.Bitcoin uses a programming language called script which has limitations. It is not turing complete and cannot solve all of the problems. On the otherhand, ethereum uses solidity and is turing complete, where it has the capacity and ability to solve all of the problems.
5. A turing complete programming language can solve all of the problems and uses a language called Loops - this allows a programmer to direct a software to do one thing several times.
