Ethereum is a decentralized blockchain with smart contract functionality. Ether (abbreviation: ETH [a]) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. [2] [3] It is open-source software. Ethereum was conceived in 2013 by programmer Vitalik Buterin. [4]
Like many cryptocurrencies, Ethereum has been tremendously volatile since its inception on July 30, 2015. But apart from the first few months while it was gaining its following, the price has ...
On 15 September 2022, the world's second largest cryptocurrency at that time, Ethereum, transitioned its consensus mechanism from proof-of-work (PoW) to proof-of-stake (PoS) in an upgrade process known as "the Merge". According to the Ethereum Founder, the upgrade would cut both Ethereum's energy use and carbon-dioxide emissions by 99.9%. [27]

Vitalik Buterin will release a book on proof-of-stake consensus on Sept. 27, compiling various writings by the Ethereum founder over the last 10 years, according to his recent Twitter post. See ...
The Merge -- the Ethereum upgrade set to take place Sept. 15 -- represents what many call "the biggest crypto event ever." From tremendously reducing Ethereum's energy consumption to the effect it...
ERC stands for "Ethereum Request for Comments," and is a part of the Ethereum community's peer-review process in which new proposals are considered for publication; the "721" is a unique identifier, each proposal is assigned one arbitrarily after an editor approves it in the draft phase.
Issues in Ethereum smart contracts, in particular, include ambiguities and easy-but-insecure constructs in its contract language Solidity, compiler bugs, Ethereum Virtual Machine bugs, attacks on the blockchain network, the immutability of bugs and that there is no central source documenting known vulnerabilities, attacks and problematic ...
