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 order to achieve this, Ethereum uses a shared global infrastructure that runs the code of these contracts. This infrastructure is Ethereum’s decentralized virtual machine, which can execute code of arbitrary algorithmic complexity.
Ethereum’s decentralized virtual machine is called the Ethereum Virtual Machine (EVM). The EVM makes it possible for anyone to run any program, regardless of the programming language given enough time and memory.
NOTE: Warning: Ethereum does not use a single database. Instead, it uses a distributed ledger, which is maintained by a global network of computers that run the Ethereum software. Anyone can become a node in the Ethereum network and store a copy of the ledger on their computer. As such, no single entity controls the data stored in the Ethereum blockchain.
The EVM is sandboxed and completely isolated from the network, file system or process of the host computer system. This allows for incredibly secure and robust smart contracts.
The EVM can be used to create all sorts of decentralized applications, including but not limited to: financial applications, social networks, voting systems, file storage systems, domain name registries and more.
What Database Does Ethereum Use?
Ethereum uses a custom-built database called LevelDB. LevelDB is a fast key-value store created by Google that uses an ordered mapping of keys to values.
Each key is associated with a value, which can be a number, a string or even another key-value pair. Keys are ordered lexicographically, which means that they are sorted alphabetically.

An Ethereum bounty is a reward offered by a party to incentivize others to complete a task or solve a problem. The most common type of bounty is a bug bounty, where developers are rewarded for finding and reporting software bugs. Other types of bounties include security bounties, community bounties, and marketing bounties. .
The Ethereum Virtual Machine (EVM) is a Turing complete virtual machine that allows anyone to run any program, regardless of the programming language given enough time and memory. The EVM makes it possible to create decentralized applications (dapps) on the Ethereum blockchain. The EVM is a key component of Ethereum and allows it to function as a world computer.
Ethereum uses a Proof of Work (PoW) algorithm, which is the most common algorithm used by cryptocurrency systems. PoW works by requiring miners to solve complex mathematical problems in order to add blocks to the blockchain. The Ethereum network is designed to be resistant to ASIC mining, which means that it is difficult for specialized hardware to be used to mine Ethereum.

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 the Ethereum protocol and blockchain there is a price for each operation. The miners are free to choose which transactions to process and they are incentivized to include the ones that pay them the most fees.
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 is used to build decentralized applications (DApps) on its platform. A DApp has front end code and a back end code.
Ethereum cold storage is a term used to describe the offline storage of Ethereum tokens. Cold storage refers to the process of storing cryptocurrencies offline, on a physical medium such as a USB drive or a paper wallet. This is in contrast to hot wallets, which are online and connected to the internet.
An Ethereum address is a unique string of characters that represents a destination on the Ethereum blockchain. Like Bitcoin addresses, they are used to send and receive Ether and other Ethereum-based assets. But what do Ethereum addresses start with?
