Homework - EVM - Ethereum Introduction

1. What does the EVM do?

A. EVM - Ethereum Virtual Machine - that consists of a piece of code on all network computer nodes, reads smart contract byte code, and executes it to Ethereum network of computers to get consensus, and block appended.
EVM also encapsulates the smart contract making sure the byte code is safe and good code.

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

A. Byte Code.

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

A. Byte Code is initially generated from smart contract instructions that are in byte code. Solidity (program language) sends its logic and instructions through its compiler to the smart contract’s byte code instructions.
The combination of smart contracts byte code with Solidity - compiler is then read by the EVM.

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

A. Because it runs on a different program language called “Script” and unlike the “Solidity” language Ethereum uses, Script has very limited programming ability and limited features such as “No” loop function - as Ethereum has unlimited programming, and more features like “Loops” function.
Bitcoin just wants to be a…Digital Gold, and not a Dapp Builder like Ethereum. Simple works best for Bitcoin, more features like “Loops” would not be good for Bitcoin network security and processing time.

5. What is a Turing Complete programming language?

A. Means you can program in anything.

[JimboSpice]

1. In short, the EVM essentially reads and executes programmed smart contracts within the Ethereum network.

2. Programmed instructions are compiled by Solidity in the form of “Bytecode”

3. The relationship between Solidity and Bytecode is that Solidity will compile programmed instructions and convert it into Bytecode.

4. Bitcoin’s programmable language is NOT Turing Complete.

5. In simple terms, a Turing Complete programming language is a language set to be able to solve any mathematical or algorithmic problem.

Feedback is appreciated

1. EVM is the Ethereum Virtual Machine, a piece of code which all nodes in the network are running. It helps to validate the smart contracts by having all nodes reaching a consensus when validating.

2. EVM only reads the byte code.

3. Solidity and Bytecode are essentially the same, just that programmers code in Solidity, which is then converted by the EVM into Bytecode.

4. Bitcoin’s programming language is not Turing Complete.

5. A Turing Complete programming language means that anything can be programmed.

What does the EVM do?

The EVM allows for the execution of smart contracts on the blockchain. It is also responsible for defining the rules for computing new blocks on the network.

@filip

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

The EVM reads instructions formatted in Bytecode.

@filip

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

Solidity is the language programmers use to create smart contracts on the Ethereum network. The code is automatically compiled into Bytecode to be read by the EVM.

@filip

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

Bitcoin’s native language is Script and, unlike Ethereum’s Solidity, Script in not Turing Complete and is therefore much more limited in its applications.

@filip

What is a Turing Complete programming language?

Turing Complete languages are capable of performing complex calculations and take their name from the Universal Turing Machine created by Alan Turing.

[SergeDoe]

• By running smart contract code on all of the nodes it ensures the code is doing the same thing.
• It encapsulates smart contract code from the CPU in a sandbox for security reasons.
• It works on top of the blockchain on top of Tx level.

2. It can read EVM bitecode.
3. Solidity allows high level abstraction for people to write smart contracts and then it is compiled to the EVM bitecode machine can understand.
4. Because Bitcoin team is not interested in developing complex application on their blockchain and is using language called Script which is not turing complete.
5. Is a language that can simulate any algorithm if sufficient time is given.

[Faisal2000]

1. What does the EVM do?
   EVM is the Ethereum Virtual Machine. EVM runs the code of the smart contract and gives it to the CPU of the node to execute.
2. What is the format of the instructions that the EVM can read?
   EVM will read the instructions in bytecode
3. What is the relationship between the programming language Solidity and Bytecode?
   Solidity will convert the programming instruction into Bytecode so that EVM can read it and give the instructions to the cpu of the node.
4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
   Bitcoin nascent language is script and is not turing complete so complex programming cannot be done on the bitcoin network nodes.
5. What is a Turing Complete programming language?
   Turing Complete programming language can handle all programming tasks and has loops.

[Bojo]

[CalionEstevar]

1. The EVM (or Ethereum Virtual Machine) executes code from smart contracts.

2. The format of the instructions that the EVM can read is byte code.

3. The relationship between the programming language Solidity and Bytecode is that Solidity code gets run through an application called a compiler that generates Bytecode that can be executed by the EVM.

4. Bitcoin can’t run the same type of complex programs that Ethereum can because its programming language isn’t as robust, since it doesn’t allow for things like loops.

5. A Turing Complete programming language is one that can solve complex problems and write complex programs.

[Surendra]

1. EVM does the following: executes contracts in each node; achieves consensus in all the nodes; ensures security through transparency.
2. EVM reads instructions in Solidity.
3. EVM is written in Solidity. This is translated to Bytecode for CPU execution.
4. Bitcoin does not have a programming language to make it dynamic.
5. A programming language is said to be Turing complete when it can execute any algorithm.

[FredLang]

1. Them EVM is a program that can read and execute smart contracts. It is a program that enables sc to be deployed on the blockchain. It is also a consensus program for all the nodes. EVM is a security layer for the cpu and can detect malicious instructions.
2. Smart contracts written in bytecode.
3. Solidity is the programming language and interface for the deceloper. Solidity compiles the sc instructions to Bytecode, which is the language the EVM can read. Other programming language may be developed on top of the Bytecode.
4. BTC has a more narrow usecase within the limitations of the language Script. Script do not allow for Turing Complete sc because of the block size constraints and scalability issues.
5. A TC complete language enables you to program anything (in theory) and deploy it to the blockchain.

[MiniJunior]

1 It isolates, reads & carries out instructs from smart contracts on the eth BC

2 Byte code

3 Programmers are using Solidity to write instructs on the ETH BC, EVM reads byte codes, therefore a complier is used to compile programming language, Solidity into bye code.

4 Programmers on the BTC BC use Script as a programming language. Script is very primitive & is limited in problem solving, hence not TC

5 Programmers can program whatever instruct they want, TC can solve any mathematical problem (in theory)

[bpmtech87]

Runs the ETH protocol on every node of the ETH network
EVM bytecode
Solidity code is human-readable but is compiled into bytecode for execution by the EVM
