Homework - EVM

1. What does the EVM do?

Etherum Virtual Machine - EVM reads and executes smart contracts (in 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?

Solidity is compiled into byte code using a compiler, and the byte code then runs (through the EVM) on the CPU of a node, just like every other programming language.

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

BTC’s uses Script as its programming language, which is not turing complete

5. What is a Turing Complete programming language?

Is a particular language code or algorithm that allows smart contracts to be programmed onto the blockchain - its a language so adaptable, any program can be written on it - this is known as turing complete

Cheers :nerd_face:

  2. Solidity and Byte code.
  3. Solidity converts instructions into byte code so the EVM can translate.

  1. The Etherium Virtual Machine is software that runs off of Etherium network node CPU in order to execute smart contracts, acting as a security measure by staying separate from computers CPU.

  2. EVM read smart contract instructions in Bytecode format

  3. Solidity is a programming language used to write smart contract, which can be compiled into ByteCode, allowing the instructions to be read by EVM

  4. Bitcoin’s programming language, script, is not “turing complete”, making it too simple to run smart contracts

  5. Turing Complete programming languages, like Solidity, allow loops and other features to be coded, which provides the complex, problem solving capability needed to create smart contracts

  1. What does the EVM do?

EVM is a program that runs on the nodes of the Ethereum network. It executes the instructions of the smart contracts and abstract it and then pass it to the CPU for executing it using the available hardware resources that Computer/node has.

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

Bytecode is the instructions format that EM can read.

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

EVM doesn’t directly read the smart contracts. Its first compiled the smart contracts to transform into
bytecodes and then the EVM can read the instructions from the bytecodes and executes the instructions using the resources available in the CPU machine.

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

Bitcoin blockchain programming language can do very primitive calculations using Scrypt language. Its not a Turing complete language. So it cant do advanced stuff like running an advanced smart contract.

  1. What is a Turing Complete programming language?

A Turing complete programming language is capable of doing any instructions setup by the programmers. You can develop any type of applications using Turing complete programming language theoretically.

  2. Byte Code.

  3. Solidity after being compiled will be translated to Bytecode and run on EVM.

  4. Because it is not Touring Complete and can not execute all kind of operations, for instance, loops.

  5. A programming language that allows execture all kind of operations.

  1. EVM can read mart contracts and execute the code. It also adds a layer of security to the etherium network by running in a sandboxed on each node of the network.
  2. The EVM reads bytecode. The code is generated by a compiler.
  3. The compiler turns the program written in solidity into bytecode that the EVM can use.
  4. BTC uses a programming language that is less complex. It is not turing complete so it can’t do loop among other things. This limits the programability of BTC.
  5. Turing complete means that you can program almost everything you want. The language has more capability and possibility than a non turing complete language

  1. EVM is a virtual machine is running on the Ethereum network. Talking to all cpu’s to run the code (smart contracts).

  2. EVM Bytecode.

  3. Solidity is the language written for Ethereum which the developer will use for the smart contracts. Bytecode is how the cpu will read the solidity code to execute the program.

  4. Bitcoin uses the script language which does not have the smart contract capability that Solidity has.

  5. Turing complete language has the ability to solve all problems such as an application, programing anything you want. Loops is what can make a language Turing complete. Script is not a Turing as it does not have the capacity to solve all problems thrown at it.

  1. EVM is like an executor, it read the smart contract before deliver it to the CPU to execute the clauses in order to avoid any malicious activity.

  2. EVM Bytecode

  3. Programming language solidity compile data into a Bytecode and put into a smart contract so that EVM can read.

  4. Because Bitcoin has limited blocksize & the turing complete programming language

  5. A turing complete programming language allow loops in the programs which mean it can instruct the CPU execute the same things over and over again for several times. This will eventually increasing the blocksize where bitcoin network is limited. But bitcoin wasn’t design to do it, it was design to be a digital gold.
