#3917

  1. It works as a security protocol that interacts with different CPU’s/nodes of a blockchain to read, confirm and deploy smart contracts.

  2. Bytecode, which is compiled on Solidity and Viper to be read by EVM.

  3. Solidity is able to compile or read the instructions written in Bytecode, which is the way we can create smart contracts on EVM.

  4. Bitcoin network was created under the PoW algorithm, which allows the nodes on its blockchain to validate the TX’s on each block. Meanwhile, while using EVM, it’s possible to create smart contracts with more complex instructions and conditions, not only focused on transactions, but also on programmable products or digital solutions.

  5. It’s a language that is not exclusively linear, that can work with different conditionals, in which you can update or re-read instructions (looping) that can vary when the deployment is running. It allows the system to work under the premise of reading and deploying new sets of rules while running a piece of code.

1- Ethereum virtual machine, or EVM for short, is a blockchain-based software platform. It allows developers to create decentralized applications (Dapps)
2- In order to efficiently store opcodes, they are encoded to bytecode
3- Smart contract languages like Solidity cannot be executed by the EVM directly. Instead, they are compiled to opcodes and to efficiently store them, they are encoded to bytecode.
4- Bitcoin is nothing more than a currency, whereas Ethereum is a ledger technology used to build new programs
5- A Turing Complete language, means everything that needs to be computed can be computed using it

EVM reads code in a script before it gets executed by the CPU like a security layer for the network.

Bytecode is the format that EVM can read.

It is the compiler which compile the instructions to bytecode.

Because Bitcoins programming language is limited by its programming language which is not turing complete.

It is a language which you can program anything with and solve and computation problem.

  1. The Ethereum Virtual Machine is a single environment that is run on all nodes simultaneously. It is the mechanism through which smart contracts are implemented on the Ethereum blockchain.

  2. The EVM can read smart contracts in Bytecode.

  3. Solidity is the user-friendly language through which smart contracts are programmed by users. This is then translated into Bytecode, the program read by the EVM.

  4. The bitcoin protocol reads a simple programming language called Script. It is NON-Turing complete by design in order to maintain the security and scalability of the bitcoin network. It doesn’t need complex programs like Ethereum because it is meant to be a decentralized monetary network and payment settlement layer. Period.

  5. It is one that is able to write code complex enough to solve any problem that a computer theoretically could solve if given enough memory, power, etc.

  • What does the EVM do?
    ans: Ethereum Virtual Machine reads and executes the commands written on smart contracts on Ethereum network
  • What is the format of the instructions that the EVM can read?
    ans: bytecodes
  • What is the relationship between the programming language Solidity and Bytecode?
    ans: Solidity compiles info data into bytecode so that smart contracts run on EVM is able to interpret and executes commands. Solidity = messenger Bytecode = message EVM = receiver and executer
  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    ans: Bitcoin is the grandfather clock which pendulum can only swing left and right (basic script), Ether is digital watch (turing complete with the ability to create loops)
  • What is a Turing Complete programming language?
    [/quote] Turing complete language is all front interactive, running Loops dynamically and repeatedly so long as the instructions are programmed within logical, theoretical framework.

  1. EVM executes a smart contract without directly interfering with your computer CPU.

  2. Smart contracts are programmed with Solidity and I suppose the output is in bytecodes, so EVM reads the instructions in bytecodes.

  3. Solidity is the tool used to program smart contracts and the program’s output is in bytecode format.

  4. Bitcoin’s script is limited and the community around it do not want to change the nature of bitcoin as digital currency. Ethereum on the other hand was proposed as a change to be included in the Bitcoin, but was refused, to keep Bitcoin in its original purpose. So, Ethereum is an alternative to Bitcoin that can run anything. It is Turing Complete.

  5. A Turing Complete language has an universal use, basically unlimited usage of the code. You can literally code anything.

1.The EVM reads the compiled solidity code (Bytecode) and tells the CPU’s of node computers what to do.
2. The format is Bytes(Bytecode)
3. The relationship is that the are the same thing however solidity is written in a more spoken way and then compiled into bytes which is then read by the EVM.
4. It cannot because it is not Turing complete. The code it can run is very limited. This was to keep the blockchain lightweight and faster.
5. Turing complete means you can code whatever you want and it can be executed and run.

Homework on EVM - Questions

1. What does the EVM do?

The Ethereum Virtual Machine (EVM) is a piece of software/application that reads off instructions embedded in smart contracts (SCs) before relaying the information to a computer’s Central Processing Unit (CPU), in order to carry out these instructions.

The EVM isolates individual SC code from a node’s operating system (OS)/CPU to prevent malicious forms of hacking from taking place.

It also represents Ethereum’s distributed computer network where all nodes run on it.

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

The code read by an EVM is usually compiled into Byte code by a Solidity or Viper compiler.

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

Solidity is a programming language developed by Ethereum that allows to code instructions in a straightforward way, which are then compiled into Bytecode using its compiler.

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

Bitcoin developers decided not to allow for looping functions (a feature of SCs) as they were concerned this feature, as well as the storage of SCs, would significantly affect the size of the Blockchain network, impact its scalability and potentially lead to loads of spamming.

Bitcoin’s programming language (Script) is also not considered Turing Complete unlike Ethereum’s Solidity/Viper.

5. What is a Turing Complete programming language?

A programming language is considered Turing Complete when anything imaginable could theoreticallybe programmable on it. Practically speaking, however, it remains to be seen whether it may actually be practical to do so (for scalability reasons, etc.)

  1. What does the EVM do?
    The EVM translates smart contract code so the nodes CPU can execute directions utilizing its local resources.

  2. What is the format of the instructions that the EVM can read?
    The instructions of the smart contract are written in bytecode

  3. What is the relationship between the programming language Solidity and Bytecode?
    Smart contracts on Ethereum are written in Solidity, a compiler application translates this to Bytecode so the EVM can read & execute instructions.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin’s programming language is limited in its problem solving capabilities, namely it is not Turing Complete

  5. What is a Turing Complete programming language?
    A Turing Complete language allows for loops, telling a program to execute specific instructions and repeat these instructions over & over again. Programming this way makes changing instructions much easier, rather than having to make adjustments to every single set of instructions, it can be modified & repeated.
