What is Ethereum?

Ethereum (ETH) is a global, open-source platform for decentralized applications. In other words, the vision is to create a world computer that anyone can build applications in a decentralized manner; while all states and data are distributed and publicly accessible. Ethereum supports smart contracts in which developers can write code in order to program digital value. Examples of decentralized apps (dapps) that are built on Ethereum includes token, non-fungible tokens, decentralized finance apps, lending protocol, decentralized exchanges, and much more.

WHAT IS BLOCKCHAIN?

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participants ledger.

The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT). Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash. This means if one block in one chain was changed, it would be immediately apparent it had been tampered with. If hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all of the distributed versions of the chain. Blockchains such as Bitcoin and Ethereum are constantly and continually growing as blocks are being added to the chain, which significantly adds to the security of the ledger.
