Homework on EVM

Ethereum 101
#401
  1. EVM runs the Smart-Contracts (SC), in each node also isolates execution of the SC code from the local OS or host machine, that is why it is called a ‘Virtual Machine’.
  2. EVM can read Bytecode
  3. Solidity is a human readable high level programming language that needs to be compiled into Bytecode to be deployed and executed in the EVM.
  4. Bitcoin script language is not a “Turing Complete” programming language.
  5. A “Turing Complete” programming language can execute all logic required to structure a complete “Turin machine equivalent” program, supporting example conditional branching and loops.

1 the EVM runs on top of the CPU and it can also read and execute smart contracts .It also ensures nothing malicious happens to the CPU
2 the EVM doesnt care about programing language ,only about the byte code/it can read turing complete languages
3 Solidity programs are complied into byte code and then run on the EVM
4 because bitcoin uses script which is not a turing complete language
5 its a programming language that supports loops and is also computationally universal

  1. The EVM makes it possible to execute code on the Ethereum network in such a way that all nodes can be in consensus about what the result is.

  2. EVM can read Byte Code

  3. Solidity --> Compiler --> Byte Code

  4. Bitcoin can’t run the same type of complex programs as Ethereum because Bitcoin can’t be programmed with a Turing-complete language.

  5. A Turing complete language is one in which practically anything the developer can imagine can be written in. Turing-complete means that it can solve any computational problem … in theory.

  1. The Evm is like a CPU in a PC taking instructions from a program, in that it takes the instructions from the smart contract instead and executes them as programmed. It is the Pow like Bitcoin but with the extra layer of having the smart contract added.

  2. The format of the instructions that the evm reads is byte code.

  3. The relationship of solidity and byte code is that solidity reads the byte code so it runs on top of the byte code.

  4. Bitcoin can not run the same type of complex programs like Ethereum because it is not a Turing and complete language and is very limited in running scripts.

  5. A Turing complete programming language will always find a result.

  1. What does the EVM do?
    EVM is a virtual machine, EVMs executes bytecode instructions in smart contracts.
  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 a human readable high level language. Solidity is compiled to bytecode in smart contracts.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    The programming language Script is not a turing complete language, meaning it has a limited instruction set, it can only do a few things.
  5. What is a Turing Complete programming language?
    A language with a full instruction set, it can do “anything”.

1, EVM (Ethereum Virtual Machine) read smart contracts (in EVM byteCode) and order Computer’s CPU what to do according to the commands;

2.The format used by the Ethereum network is called Bytecode.

  1. Solidity is a programming language for Bytecode

  2. Bitcoin uses a much simpler programming language (called Script) that does not allow smart contracts to be built on top

  3. Turing Complete language means that complex application can run on top of the ETH Blockchain

  1. EVM is the most important program that ensures the security and the transparency of the Nodes that each computer has. And help read all the tasks to process and tells the CPU to execute the actions. The EVM is the Ethereum Virtual Machine that executes smart contracts on all nodes within the Ethereum network. It is an application that each node has installed to read smart contracts and interpret them to the CPU of each node. It can be viewed as the translator, middleman, or even bodyguard between smart contracts on the network and the CPU of each node.
  2. EVM can read all the actions that Nodes will do and process and have access to the whole computer. We mean that it securely encapsulates the smart contract so it is not exposed to the CPU or any other program on the computer. In this way, it ensures that a node’s operational security is not compromised by any malicious code that might have been included in the smart contract.
  3. Solidity programming language runs through the Bytecodes
  4. Because the Bitcoin programming language Script is not complete turing complete programming language.
  5. It is the Language that enables you to program more in a complete way. You can program your Blochchain transaction with complete total security that the blockchain system can offer.

  1. EVM (Ethereum Virtual Machine) is an application that reads all instructions, executes the code and lets CPU know what to do.
  2. EVM reads in byte code and executes instructions in accuracy.
  3. Solidity is like java script- a true complete language and ensures nothing wrong will happen to smart contracts. Viper is the relationship between the both
  4. Bitcoin runs/uses SCRIPT, which is not Turing complete, whereas Ethereum uses TC.
  5. Solidity is a Turing Complete Language.

  1. What does the EVM do?
    The Ethereum Virtual Machine is installed on all computers within the network. The EVM uses the compute power of network CPU’s to execute the code of a smart contract on the Ethereum network.

  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?
    In a program like solidity, you write code in a simplified language that looks like English. Then Solidity converts this into byte code.

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

  5. What is a Turing Complete programming language?
    A Turing Complete programming language can execute loops, etc. It can execute code for anything you can imagine/program.

1 - The EVM runs the smart contracts while protecting the hardware for mining
2 - EVM reads Bytecode
3 - In order to write smart contract the programing language needed is solidity. Then it’s converted into bytecode so that the EVM can read it.
4 - bitcoin uses scrypt and is not a Turing Complete programing language.
5 - Touring complete languages allow to build other applications and functions. For instance loops.

What does the EVM do?
EVM is the Ethereum virtual machine. The EVM runs on top of the CPU´s and create the space where smart contracts run.

What is the format of the instructions that the EVM can read?
The EVM only reads in bytecode

What is the relationship between the programming language Solidity and Bytecode?
The developer write in Solidity and then Solidity translate the code into bytecode on the contract

Why can’t Bitcoin run the same type of complex programs like Ethereum can?
You cant do loops on the bitcoin code Script, they would not allowed this, because it could create spam on the blockchain, and each TX would be bigger in size because more code would be inside.

What is a Turing Complete programming language?

  1. What does the EVM do? EVM provides a form of security and confirmation for smart contracts before the smart contract is deployed on the etherium network.
  2. What is the format of the instructions that the EVM can read? The instructions are compiled into Bytecode, but written in Solidity or another type of code.
  3. What is the relationship between the programming language Solidity and Bytecode? Solidity is what the smart contract is written in which is then compiled into Bytecode.
  4. Why can’t Bitcoin run the same type of complex programs like Etherium can? Because Bitcoin was made to be online money. It’s programming language isn’t meant to run complex programs because it is not turing complete.
    5.What is a Turing Complete programming language? A Turing Complete programming language is in theory able to solve any problem that is coded with that language.

  1. The EVM runs on top of the hardware of each node in the Ethereum network, acting as a middleman between the smart contracts and the CPU of the nodes, by reading and executing the smart contracts and giving instructions to the CPU to execute the smart contracts on each node.
  2. The instructions that the EVM can read are written in byte code, after the compiler has translated them from Solidity programming language.
  3. The programming language Solidity writes the smart contract, which is translated in byte code by the compiler, making it easier for the EVM to read and deploy the smart contract.
  4. The programming language of Bitcoin is Script, which is NOT a Turing Complete programming language, meaning it cannot write and run really complex instructions like those of smart contracts.
  5. A Turing Complete programming language like Solidity is able to do any calculation you want with it, like those involved in the deployment of a smart contract. Concerning Ethereum, with Solidity is theoretically possible to do anything, but there are some scalability issue that might impede that.
