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.
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 ...

Wegner [152] stated that "interoperability is the ability of two or more software components to cooperate despite differences in language, interface, and execution platform". The objective of blockchain interoperability is therefore to support such cooperation among blockchain systems, despite those kinds of differences.
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]
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 ...
The Ethereum blockchain popularized smart contracts, which are the basis of DeFi, in 2017. Other blockchains have since implemented smart contracts. As of 2021, MakerDAO was a prominent lending DeFi platform based on a stablecoin that was established in 2017. [7] [8] It allowed users to borrow DAI, a token pegged to the US dollar.
