Ethereum is a public, open-source, decentralized computing platform featuring smart contract functionality. It enables developers to build and deploy decentralized applications.
The native cryptocurrency of the Ethereum network is ether (ETH). ETH is used to pay transaction fees and gas prices.
Gas is a unit of measurement that denotes the computational work required to execute a transaction or a smart contract.
Ethereum has two types of accounts: externally owned accounts (EOAs) and contract accounts. EOAs are controlled by private keys and can send transactions.
Contract accounts are controlled by their contract code and can interact with other contracts, but they cannot initiate transactions themselves.
The Ethereum Virtual Machine (EVM) is the runtime environment for smart contracts in Ethereum. It is a 256-bit register stack, capable of executing code of arbitrary complexity.
NOTE: WARNING: Ethereum is not UTXO based. Transactions on the Ethereum network are not based on the UTXO model like Bitcoin, but instead use a different type of transaction model called “account/balance” which stores account balances in the blockchain. Ethereum does not use unspent transaction outputs (UTXOs) to track user balances, instead it uses individual accounts with balances that can be increased or decreased by transactions. As a result, it’s important to understand how Ethereum works differently than Bitcoin when it comes to transactions and accounts.
In order to run a smart contract on the EVM, it must be first deployed on the Ethereum blockchain. The process of deploying a smart contract on the Ethereum blockchain is called “mining”.
Mining is how new units of ETH are created. When a miner mines a block, they are rewarded with ETH.
The amount of ETH rewarded is proportional to the amount of computational work done by the miner.
The Ethereum blockchain is UTXO based. This means that each account has its own balance and that the total balance of all accounts must always be equal to zero.
When a transaction is made, the sender account’s balance decreases and the recipient account’s balance increases by an equal amount.
A key feature of UTXO-based systems is that they are very resistant to double-spending attacks. In order to successfully double-spend an ETH token, a attacker would need to have more than half of the total number of ETH tokens in circulation.
This is known as the 51% attack and it is considered to be very difficult, if not impossible, to achieve.

Yes, Ethereum uses the UTXO model. The UTXO model is a data structure that is used to keep track of unspent transaction outputs. In the UTXO model, each transaction has a list of inputs and outputs.
Ethereum, the world’s second-largest cryptocurrency by market capitalization, does not have a UTXO model. Instead, it has a account-based model. In a UTXO model, each transaction outputs can only be used as inputs in future transactions.
Ethereum is not a UTXO system. While both Bitcoin and Ethereum use blockchain technology, they have different design philosophies. Bitcoin was designed as a peer-to-peer electronic cash system.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Ethereum uses a public blockchain similar to Bitcoin’s, but also enables advanced programmable transactions known as smart contracts. Smart contracts are digital contracts that can be programmed to run automatically when certain conditions are met.
Ethereum UTXO is a blockchain. A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings.
In the cryptocurrency world, there are many different types of coins and tokens. Some of these tokens are built on top of existing blockchain platforms, while others are their own standalone blockchain. CHZ is a token that falls into the latter category.
Ethereum uses an account-based model, where each account has its own balance. In contrast, Bitcoin uses a UTXO model, where each UTXO represents a certain amount of Bitcoin that can be spent. The UTXO model has some advantages over the account-based model.
OXT is not an Ethereum. Created by the team at blockchain startup Blockchain, OXT is a digital asset designed to give users control over their digital information. OXT is built on the Ethereum blockchain and utilizes the Interplanetary File System (IPFS) to store data.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. In 2014, Ethereum launched a presale for ether, which received an overwhelming response. Ether is like the fuel for operating the distributed application platform of Ethereum.
