  1. Ethereum Virtual Machine (EVM) executes bytecode. The Bytecode that the EVM receives is compiled from the programming language Solidity which is what Ethereum blockchain developers use to write code.
  2. The format for the instructions is Bytecode.
  3. When programmers program on Ethereum, they write in Solidity, the language Solidity is then compiled into EVM Bytecode.
  4. Bitcoin is programmed with script, a non Turing complete programming language. While it is capable of very basic smart contracts, it is more limited than what you can do with Solidity. Solidity is a Turing complete programming language with the ability to create Loops. This makes it very capable for complex programs to be made, and other abilities such as Smart Contracts.
  5. A Turing Complete programming language is a language that can technically solve any problem. Simply put a “Turing Machine” is the concept of an infinite tape of cells with ones and zeros. A little robot with a read/write head hovers over one box at a time, and is able to read what is in said box, and answer an “If then else” question. This concept is what lets any problem be solved… However the catch is there’s no guarantee how long said problem would take to be solved.

1. What does the EVM do?
The EVM reads a smart contracts commands/instructions and then tells the CPU to run them. EVM also adds security by making sure the commands are safe to run so malicious smart contracts can’t read data about the Ethereum node.

2. What is the format of the instructions that the EVM can read?
The format of instructions is called EVM byte code:

  • Solidity (or Viper, etc) code -> compiler -> EVM Bytecode -> EVM

3. What is the relationship between the programming language Solidity and Bytecode?
Solidity (similar to JavaScript) is a language that can compile code to EVM Bytecode.

4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Bitcoin is not turing complete, meaning it can only run very simple programs; Bitcoin (unlike Ethereum) doesn’t support loops, for example.

5. What is a Turing Complete programming language?
A Turing Complete language is able to solve any complex computational (mathematical) problems.

Good evening!

  1. The Ethereum Virtual Machine connects all nodes on the Ethereum network who have a version of the EVM so that there is a consensus as to what smart contracts exist on the Ethereum Blockchain at all times.
  2. The format of the instructions the EVM can read is compiled code written in either languages, Solidity or Viper, that is in in the form of byte code.
  3. Solidity is a programming language that details the instructions and compiles them into another code called byte code (commonly used as a readable format by a “virtual” machine rather that computer machine).
  4. The Bitcoin Blockchain is more basic in nature and can only perform the very simple back and forth of transactions. Everything about it’s network would have been modified (size, speed of blocks for example) if the programming that is now on the Ethereum network was implemented.
  5. A Turing Complete programming language is one in which it can “loop” functions or instructions to a point.

1 It uses the CPU of all the computers connected and not just one
2
3 Bytecode is the ultimate language EVM reads regardless the programming language has been used to write the smart contract. Solidity is one of these programs
4 Because the bitcoin blockchain is way more simple than ETH and BTC should just be considered as the digital gold resource as it is.

  1. What does the EVM do?
  • The EVM runs on every node in the Ethereum network and translates smart contract byte code to CPU readable code. The EVM processes the smart contract by reading byte code instructions and forwarding the according CPU commands to the CPU.
  1. What is the format of the instructions that the EVM can read?
  • EVMs can read compiled code from a programming language such as Solidity, which is in the form of byte code.
  1. What is the relationship between the programming language Solidity and Bytecode?
  • Solidity is a programming language using human readable statements to achieve a result. Computing entities, such a CPU is, cannot work with human readable statements, these statements need to be „translated“ (either compile the complete code or interpret line by line during the execution). Solidity uses a compiler to transform human readable statements in a machine readable format, wich in that case is byte code.
  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
  • Bitcoin has not been designed to execute complex code during a transaction has been processed. Complex code occupies memory space so it would lower the transaction space and increase the transaction fees. Executing further code in addition to forwarding bitcoins would also lower the execution speed of blocks, wich also leads to higher transaction fees.
    1. What is a Turing Complete programming language?
  • A Turing Complete programming language provides simple means to perform loops, i.e. the programmer can use a single statement to call a loop procedure without taking care of how this loop is organized internally.

  3. What is the relationship between the programming language Solidity and Bytecode?
    SC is written in solidity, compiled into bytecode, evm reads bytecode and tells CPU what to do
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin is not turing complete meaning you cannot program it to perform any action. One of the reasons for that are the loops which bitcoin is protected from because loops could spam the blockchain into piece of unusable code
  5. What is a Turing Complete programming language?
    Turing Complete means you can program sc to do anything

  1. What does the EVM do?

The EVM allows for smart contracts to be executed across the Ethereum blockchain.

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

The EVM reads Bytecode. Solidity is the programming language that get transcribed into Bytecode by a compiler called Viper.

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

Bytecode is the transcribed information by the compiler Viper from the programming language Solidity.

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

Bitcoin is not turing complete, and the block sizes would become unmanageable. Only specific programming can be done on the Bitcoin blockchain. Ethereum is turing complete allowing for programming flexibility.

  1. What does the EVM do?
    EVM – or Ethereum Virtual Machine – is a little piece of code that runs on each Node in the Ethereum blockchain network of computers, which runs on top of the Node’s hardware (CPU) and will utilize the CPU and all the resources the Node has.
    Similar to how a Bitcoin blockchain uses the Proof of Work Consensus algorithm to mine Transactions, Ethereum adds an additional layer to this, which is EVM.
    The EVM reads and executes code (Smart Contracts) on the network and controls the hardware (CPU) on the Node in such a way where all Nodes are in Consensus about what the results should be. After each Node executes the Smart Contract and receives a result, ALL Nodes will be in Consensus if they ALL have the same result.

  2. What is the format of the instructions that the EVM can read?
    A compiler will take a programming language’s Smart Contract and compile it down to Bytecode where the EVM can now read and execute the instructions.
    Smart Contracts may be written using the Solidity programming language (similar to JavaScript, which looks like English in many ways), and then compiled into Bytecode.
    Ethereum is working on a new programming language, called Viper, which will also compiles to the same Bytecode. Viper will be written differently than Solidity.
    The EVM doesn’t care about which programming language you use; EVM only cares about executing the Bytecode that it receives.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Smart Contracts in the Ethereum blockchain may be written using the Solidity programming language (very similar to JavaScript), compiled into Bytecode, and the Ethereum Virtual Machine can execute the Bytecode (instructions of the Smart Contracts) on the Node.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin was designed to be digital gold; nothing else.
    Bitcoin has a programming language called “Script”, where you can program very simple instructions on Bitcoin (e.g., script a multi-sig Wallet, which means multiple people signing the Transaction, before the Transaction goes through). But they’re not really Smart Contracts, because they have very limited capability.
    The “Script” language in Bitcoin is not a Turing Complete language as it cannot solve all problems that it might have to solve if you want to program a Smart Contract. A Turing Complete language must contain loops. Loops is a feature in a programming language that gives the ability for software to do ONE thing MULTIPLE times (e.g., do these set of instructions 1,000 times).
    Bitcoin developers wanted to avoid loops to prevent SPAM, and they also wanted to limit the Blockchain size since you would have to store all the Smart Contracts on the blockchain.

  2. The format of of instructions that the EVM can read is byte code that is written primarily as using Solidity but ultimately can be written in any language that produces byte code.
  3. See (2) above
  4. Bitcoin’s programming language ‘Scripts’ is not ‘Turing complete’ and thus cannot solve all problems that come before it.
  5. A Turing program can handle any problem that comes before it through programming ability, scripting and looping.
