Solidity was proposed in August 2014 by Gavin Wood [13] [non-primary source needed] The language was later developed by the Ethereum project's Solidity team, led by Christian Reitwiessner. Solidity is the primary language used to develop smart contracts for Ethereum as well as other private blockchains , such as the enterprise-oriented ...
Ethereum-based permissioned blockchain variants are used and being investigated for various projects: In 2017, JPMorgan Chase proposed developing JPM Coin on a permissioned-variant of Ethereum blockchain dubbed "Quorum". [87] It is "designed to toe the line between private and public in the realm of shuffling derivatives and payments.
The Ethereum Foundation applied their trademark to the new, altered version of the Ethereum blockchain. [2] The older, unaltered version of Ethereum was renamed and continued on as Ethereum Classic. [2] Ethereum Classic's native Ether token is a cryptocurrency traded on digital currency exchanges under the currency code ETC. [3]
The decentralized blockchain may use ad hoc message passing and distributed networking. [38] In a so-called "51% attack" a central entity gains control of more than half of a network and can then manipulate that specific blockchain record at will, allowing double-spending. [39] Blockchain security methods include the use of public-key cryptography.
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 ...

Polygon (formerly Matic Network) is a blockchain platform which aims to create a multi-chain blockchain system compatible with Ethereum. As with Ethereum, it uses a proof of stake consensus mechanism for processing transactions on-chain. Polygon's native token is POL, an ERC-20 token which allows for compatibility with other Ethereum ...
Buterin is the inventor of Ethereum, described as a "decentralised mining network and software development platform rolled into one" [24] that facilitates the creation of new cryptocurrencies and programs that share a single blockchain (a cryptographic transaction ledger). [25] [26] [27]
