[Jay_Vanaparthy]

1. It execute the commands/rules in the Smart contract one by one.
2. Byte Code
3. Solidity write the Program in Byte Code that is readable by EVM.
4. Bitcoin writes very simple programs so the block is not spammed, Block size can be less and latency can be avoided.
   5.Turing Complete - Complex code can be written on the Ethereum network using Solidity.

[Alex_L]

1. What does the EVM do?
   Ethereum Virtual Machine will calculate the blockchain node and instruct the CPU to indirectly complete the Blockchain. This feature makes is possible to add instructions in the protocol and keeping your CPU secure and introducing the smart contract.

2. What is the format of the instructions that the EVM can read?
   The format is in byte code and can be read and written in a program language called Solidity.

3. What is the relationship between the programming language Solidity and Bytecode?
   The format is in byte code and can be read and written in a program language called Solidity.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   The bit coin script is not Turing Complete, meaning the script does not enable loops in the protocol.

5. What is a Turing Complete programming language?
   Will have no limits in the programming, loops in the programming is essential in Turing compelte programming but is very risky and if not programmed correctly it can cause a never-ending loop taking all resources to continue.

[Jaidan905]

1. An Evm is a smart contract reader

2. Bytecode

3. Once you write the code in Solidity then you put it in a compiler that will put it into Bytecode.

4. Because its not Turing complete.

5. A Turing complete language is an appplication that you can do everything with. Meaning it has no limits and can do pretty much everything.

[ThiAze]

1. What does EVM do?

A1 - The EVM reads the instructions written in bytecode and acts as an intermediary for the CPU to execute the instructions established in the smart contracts;

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

A2 - Bytecode;

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

A3 - Solidity is the programming language that will compile the logic of the instructions and transform them into bytecode;

4. Why can’t Bitcoin run the same kind of complex programs as Ethereum can?

A4 - First because of the purpose that Bitcoin proposes, to be a currency. Second, because it uses a limited programming language called Script;

5. What is a Turing Complete programming language?

A5 - Programming language that makes it possible to execute actions in an unlimited way and can solve problems that must be solved. Therefore, everything you want to program is possible.

[Epicdisaster]

1.The EVM reads and executes smart contracts.
2.Bytecode
3.Solidity translates a language that is easy to understand for humans into bytecode which will be executed by the CPU.
4.Bitcoin can’t run the same type of complex programs like Ethereum because it’s not turing complete.
5.A Turing Complete programming language is a language which can solve any computation problems.

[Jmoff]

1. What does the EVM do?

EVM ensures all nodes in the Ethereum network are in consensus when a transaction occurs. It also makes sure that any smart contract that enters the Ethereum network is not malicious, ensuring the blockchain cannot be compromised.

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

EVM reads instructions from a Solidity program compiled into bytecode before executing the program into the smart contract on the Ethereum network.

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

Solidity is the language used to write smart contracts on the Ethereum network. When a program is written through Solidity, it runs through a compiler that breaks it down into bytecode for the EVM to read. Once the EVM understands the smart contract is not malicious, it enters the Ethereum network through a user’s CPU.

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

The programming language of the Bitcoin network, script, is not Turing Complete. Script does not know what a smart contract is and therefore cannot run the same way as the Ethereum network. Furthermore, the developers of Bitcoin, intended for the cryptocurrency to be digital gold, nothing more.

5. What is a Turing Complete programming language?

A language that can execute any action you want it to; it’s essentially as smart as a programming language can get.

[nmilka]

1. EVM reads and forwards commands to the CPU on the nodes, hence executing smart contracts deployed on the ETH network.
2. Bytecode - contracts are written in solidity or Viper, and compiled into bytecode.
3. Solidity is the human readable program code, which is translated into bytecode by the compiler.
4. It doesn’t have a turing complete progamming language.
5. A TC programming language can run any code and find solution to any problem (in theory) without any limit.

[Huddoh]

1. What does the EVM do?

EVM (Ethereum Virtual Machine) reads the instructions of a smart contract, and communicates it to the CPU’ of each node in the network, in order that they may execute it to determine the result of the smart contract i.e how said smart contract is meant to behave or what it is meant to do.

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 has a special application called a compiler that reads the logic and the instructions of a smart contract, and then deduces the Bytecode (which the EVM reads)

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

Bitcoin can’t run such programs because its native programming language ‘script’ is not Turing Complete.

5. What is a Turing Complete programming language?
A Turing Complete programming language is one that can handle complex instructions.

A TC language is one that is programmable and malleable and as such can be utilised to solve a wide variety of programming problems.

[ppoluha]

1. It’s a “virtual machine” sitting on top of the cpu, interpreting the code and making sure the code is not doing something malicious.

2. It’s called Ethereum Virtual Machine (EVM) Byte Code.

3. Solidity is compiled (translated) into byte code.

4. The bitcoin language (script) is not “turing complete”, meaning it’s very limited.

5. A turing complete language can solve any computational problem.

[fredliberman]

1. What does the EVM do?
   EVM is an application running on all the nodes of the network, reading and tell the CPU of each node to execute the instructions in the Smart Contrats

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 instructions are converted into bytecode that EVM can read and execute.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   BTC native programing language Script is not Turing complete.
   In addition BlockChain size is a real contraint on BTC and its vision is to be a gold digital currency.

5. What is a Turing Complete programming language?
   Turing Complete means that the programming language can solve any mathematical problems and that the language included “loops”

[reggie_nash]

1. The EVM(Ethereum Virtual Machine) is what converts the instructions of the smart contract from bytes and tells the computer how to execute each command of the smart contract.
2. The format of the instructions red by the EVM is in bytes.
3. Solidity is the language that smart contracts are written in to be deployed in the Ethereum Blockchain. Solidity is converted into bytes in order to be read by the EVM, so that the code can be implemented by the computer.
4. Bitcoin simply wasn’t created with those capabilities. Bitcoin has a language called script that can perform primitive “smart contracts”, but it can’t produce anything advanced. In addition. Bitcoin doesn’t have an EVM checkpoint so there is a security issue if a complicated smart contract with millions of loops was run on the Bitcoin Blockchain. The script Language is not Turing Complete.
5. A Turing Complete language is a language that is not complete, namely it does not have loops. A Turing Complete language theoretically gives you the ability to code anything in your imagination.

[Groyper]

1. The EVM provides the framework for nodes to execute smart contracts. It also provides security my preventing malicious smart contracts from infecting the host computer.

2. Bytecode.

3. Solidity converts complex programing language into bytecode.

4. Because bitcoin uses the script language, which is not turing complete. Bitcoin is designed to be a simple and effective currency, so adding the complexity of smart contracts on top of it would only hinder the effectiveness of its primary purpose.

5. A programming language that has the diversity of language to solve every problem needed

[rachel]

1. EVM is the ethereum virtual machine that runs on every node to read and execute smart contracts within the ethereum network and interprets the code to the CPU.

2. the EVM runs in a sandbox environment which means it is isolated from other hardware on the computer, so smart contracts within EVM cannot harm the CPU. it acts as a secure layer between the code and the computers hardware

3. solidity is a programming language that is converted into bytecode when in the EVM so the instructions can be translated by the CPU.

4. bitcoin uses different programming systems with simpler script, the language is not turing complete.

5. turing complete language can program any function, it allows scripts (command) to be looped, run constantly and can perform any task theoretically.

[yllee9127]

   To execute Ethereum smart contracts as bytecode.

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 compiled, machine readable version of Solidity.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Bitcoin does not have Turing complete programming language, instead it uses simple scripting language…

5. What is a Turing Complete programming language?
   It is a complete programming language that is capable of performing any function, such as looping.

[cryptcat]

• What does the EVM do? The EVM is a code that provides consensus for all nodes in the Ethereum ecosystem. It is responsible for executing smart contracts (that are written in high level programming languages- currently dapps are mostly written in Solidity) by reading them via a compiler, which translates them into EVM’s language of bytecode. The EVM functionally provides individual machines protection from maliciously written code that could insert instructions to facilitate hacking, as it is an isolated processing code separate from host functions. This provides it the ability to execute smart contracts in a trustless environment.

• What is the format of the instructions that the EVM can read? The EVM reads bytecode which is what a complier translates the solidity programming language into.

• What is the relationship between the programming language Solidity and Bytecode? A dapp’s smart contract is written in solidity’s programming language and via a ‘compiler’, is translated into Bytecode, which is what the EVM reads. This is imperative for consensus functioning so that each Ethereum node is executing the smart contract the same way, and so that the smart contract is executed the same way every time by a node.

• Why can’t Bitcoin run the same type of complex programs like Ethereum can? Bitcoin only is able to support transactional functionality through a programming language called Script, which is NOT a turing complete language. It does this by providing instructions to wallets regarding UTXOs.

• What is a Turing Complete programming language? Turing complete and turing incomplete refer to a programming’s ability to engage in decision making given a defined set of rules. ‘Turing incomplete’ refers to a machine’s ability to execute a decision that is defined by specific instructions on how to execute that process. ‘Turing complete’ means that the machine is able to engage in decision making that is able to execute an independent decision based on a defined set of conditions. This difference in programming language defines the significant differences in Bitcoin and Ethereum processing capabilities- bitcoin is a turing incomplete language, and Ethereum is a turing complete language; hence Ethereum is able to read and execute smart contracts and bitcoin cannot. That is also why gas is needed on Ethereum- to protect against looping.

2. Bytecode

3. Smart contracts are written in Solidity, which is then compiled into Bytecode.

4. It is not Turing Complete to avoid spam.

5. A Turing complete programming language allows the programmer to do whatever they want, program whatever they want.

[Nuno_Silva]

1. The EVM is a virtual machine running on the Ethereum blockchain. It’s where the smart contracts are run and it’s porpose is preventing that nodes runs the smart contract in their own hardware directly. IT’s a sandbox for smart contracts and provides a layer of security to the nodes.

2. The EVM reads Bytecode, so the language of the smart contract should be compliled to Bytecode.

3. Solidity is the programming language for smart contracts on Ethereum.

4. Bitcoin has a Non Turing Complete language called script, and to prevent network spam it does not accept loops.

5. Being a Turing Complete language means that (theoretically) it can solve any computacional problem.

[jacobksmith34]

1. The EVM (Ethereum Virtual Machine) reads and deploys smart contracts to the network in order to execute the program. It also checks the code for security issues to insure no malicious attacks to the ethereum network.

2. The EVM reads solidity programming language which is converted into readable bytes.

3. Bytecode is simply a formatted version of the solidity code that is readable by the EVM.

4. Bitcoin programmers did not want complex programs to clog the network, nor did they want the possibility of malicious programs being sent out through the network. Therefore, ethereum was created that could run all types of applications.

5. A turing complete programming language is programmed to find an answer. This means in theory, it can solve any computational problem and allows for limitless applications to be built on the network.
