As explained in our guide “How Ethereum Mining Works“, miners are the ones that are preventing bad behavior – like ensuring that no one is spending their money more than once and rejecting smart contracts that haven’t been paid for.
January 18, 2019, 10:55:12 AM
Actual computation on the EVM is achieved through a stack-based bytecode language (the ones and zeroes that a machine can read), but developers can write smart contracts in high-level languages such as Solidity and Serpent that are easier for humans to read and write.
January 18, 2019, 10:31:41 AM
In this part the EVM executes a contract with whatever rules the developer initially programmed.

Bitcoin miners validate the shift of ownership of bitcoins from one person to another.
January 18, 2019, 10:27:40 AM
The goal here is for the network of miners and nodes to take responsibility for transferring the shift from state to state, rather than some authority such as PayPal or a bank. 
January 18, 2019, 10:05:14 AM
That every time a user performs some action, all of the nodes on the network need to come to agreement that this change took place.

But we have to remember that every node in the network holds a copy of the transaction and smart contract history of the network, in addition to keeping track of the current ‘state’.
January 18, 2019, 09:54:14 AM
All the nodes execute this contract using their EVMs. January 18, 2019, 09:53:44 AM
Contracts written in a smart contract-specific programming languages are compiled into ‘bytecode’, which a feature called the ‘ethereum virtual machine’ (EVM) can read and execute. 
January 18, 2019, 09:52:32 AM
With ethereum, every time a program is used, a network of thousands of computers processes it.
January 18, 2019, 09:50:06 AM
Now, with that clear what is the ethereum virtual machine?
January 18, 2019, 09:49:03 AM
Funds are always somewhere, but don’t have what you might call a continued relationship. 
January 18, 2019, 09:45:59 AM
Like bank account funds, ether tokens appear in a wallet, and can be ported (so to speak) to another account.
January 18, 2019, 09:44:26 AM
Ethereum, on the other hand, uses accounts.
January 18, 2019, 09:43:59 AM
In order to make future transactions, the bitcoin network must add up all your pieces of change, which are classed as either ‘spent’ or ‘unspent’.
January 18, 2019, 09:42:20 AM
Every time a bitcoin transaction is made, the network ‘breaks’ the total amount as if it was paper money, issuing back bitcoins in a way that makes the data behave similarly to physical coins or change.
January 18, 2019, 09:39:07 AM
While it sounds more complex, the idea is fairly simple. And you will see why in a few minutes!
January 18, 2019, 09:38:37 AM
Bitcoin uses unspent transaction outputs to track who has how much bitcoin.
January 18, 2019, 09:33:07 AM
For each ethereum application, the network needs to keep track of the ‘state’, or the current information of all of these applications, including each user’s balance, all the smart contract code and where it’s all stored.
