Homework on EVM - Answers

  1. What does the EVM do?
    The EVM uses node hardware to take information contained in smart contracts and uses that info to issue commands the nodeā€™s CPU in order to execute the intended function of the smart contracts. A version of the EVM exists on every node in the network, and a smart contract must be propagated to every node and verified by every version of the EVM to be validated by consensus.

  2. What is the format of the instructions that the EVM can read?
    The EVM can only read smart contracts that have been compiled in Bytecode.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Programmers use Solidity to write smart contracts on the Ethereum chain, whereas Bytecode is read by the EVM. Bytecode is Solidity (or also Viper) that has been compiled in order to be read.

  4. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoinā€™s language, Script, is limited in function due to not being a Turing Complete language, meaning that it inherently cannot perform any function like Solidity, a Turing Complete language, can.

  5. What is a Turing Complete programming language?
    A Turing Complete language is a language that can be used to program anything that can be imagined, from loops to very complex applications.

  1. The EVM runs the smart contract. It does so instead of the CPU for security reasons.
  2. The EVM can read instructions under bytecode format, which is actually the result after the Solidity code being compiled.
  3. Solidity code, after being compiled, outputs Bytecode, which is readable by the EVM.
  4. Bitcoin runs a simplest smart contract. It doesnā€™t contain complex conditions like programs on Ethereum. It is so because Bitcoin inventors donā€™t want the blockchain to be spammed by complex instructions that have an impact on the entire network.
  5. A Turing Complete programming language allows a complex program to run. It allows the programmers to specify any condition for the program to run.

  • What does the EVM do?
    EVM or Ethereum Virtual Machine is a network of computers which uses consensus algorithm to execute code on the network to produce smart contracts.

  • What is the format of the instructions that the EVM can read?
    The EVM can read Turing Complete language such as Solidity or Viper by reading their byte codes and compiling them and then executing these into the the EVM network to verify the smart contract.

  • What is the relationship between the programming language Solidity and Bytecode?
    The relationship between the Solidity and bytecode is that Solidity contains the instructions from the CPU. When these interact with the EVM, these solidity instructions are then converted into EVM bytecodes and the EVM bytecodes then tells all the CPUs in the nodes to execute leading to a final result on the Smart Contract.

  • Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin already uses the programming language called Scripts and it is not Turing Complete therefore it is limited and cannot necessarily program anything you want; unlike in Turing complete programming language.

  • What is a Turing Complete programming language?
    A Turing Complete programming language is a language that allow loops to occur in the instructions and you can program anything you want.

  1. What does the EVM do?

The Ethereum Virtual Machine is the component of the Ethereum network that manages the deployment and execution of smart contracts. The EVM runs on top of each full nodeā€™s CPU and it can read and execute smart contract code (bytecode). It plays a vital role for the network to reach consensus about the validity of a smart contract and whether or not to deploy it on the blockchain. To make the network more secure from smart contracts that contain malicious code, the EVM encapsulates the smart contract from the network by creating a level of abstraction between the executing code and the node that is executing the code such that the smart contract never has direct access or control over a nodeā€™s CPU.

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

The EVM can read code in bytecode format.

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

A relationship between Solidity and Bytecode is established using a compiler that compiles Solidity code in Bytecode. A programmer writes a smart contract in Solidity which is then compiled in Bytecode to make it readable to the EVM.

  1. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?

The complex programs on the Ethereum network are based on a turing complete language that allows to write code that can execute complex tasks. Bitcoin uses a language that is not turing complete, meaning the code can only be used to perform simple tasks.

  1. What is a turing complete programming language?

A turing complete language makes it possible to write code that is capable of performing any logical step of a computational function, given the computer that runs the code has sufficient resources and time. A turing complete language can be used to write code that performs complex tasks.

1. What does the EVM do?

The Ethereum virtual machine is similar to a virtual computer that reads the code of the smart contract, then tells the CPU what to do.

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

The EVM can only read byte code.

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

Solidity is the programming language that can be converted to byte code by a compiler. The EVM cannot read Solidity code, so it has to rely on the compiler to ā€œtranslateā€ it into byte code.

4. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?

Bitcoin uses Script, which is a non-Turing Complete programming language. That means that it cannot solve all problems or run very complex programs such as complex smart contracts.

5. What is a Turing Complete programming language?

A Turing Complete programming language is a language that could, in theory, be used to solve any computation problem, regardless of its difficulty or complexity. Unlike non-Turing Complete languages, it has the ability to code for loops, in which a piece of code can repeat itself many times before proceeding with the rest of the program.

  1. What does the EVM do? The Ethereum Virtual Machine is the mechanism the Ethereum network uses to read smart contracts and achieve consensus on the network about the contents of smart contracts. The EVM also provides security on the network by preventing a malicious smart contract from high-jacking the network. The EVM runs on all Ethereum nodes.

  2. What is the format of the instructions that the EVM can read? The EVM reads instructions in EVM byte code. This byte code is written in higher-level languages like Solidity and Viper.

3.What is the relationship between the programming language Solidity and Bytecode? Through the EVM compiler the human-readable code from Solidity is translated into EVM byte code that facilitates carrying out the actions of the smart contract.

  1. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can? Bitcoin can be programmed in a manner similar the Ethereum but on a much more basic level using its instructional language call Script. This is a non-Turing Complete language that limits the overall functionality of Bitcoin. This is because the Bitcoin community has decided that BTC will continue to act only as a store of value and a means of exchange; gold 2.0.

  2. What is Turing Complete programming language? Turing Complete means that the language can support any algorithm the developer can imagine. More specifically, Turing completeness incorporates the use of looping structures.
