Ethereum is a decentralized platform with smart contracts. Ethereum is considered the father of the 2nd generation of cryptocurrency (1st generation - Bitcoin), as its team was able to create a completely new use for the blockchain. It is now possible to create smart contracts in the blockchain, in which it is possible to clearly mark the conditions of implementation for the execution of obligations. Thus, the Ethereum coin itself serves as a “fuel” for the execution of smart contracts.Thanks to this platform, it has become easier to create decentralized projects, since there is no need to create an IT infrastructure and a thorough study of blockchain technology. Due to this, the platform can be used by government agencies and businesses by loading their bases in the Ethereum blockchain. This will help to get rid of two problems: forging databases and long search for information.The platform itself was developed by the non-profit association “Ethereum Foundation”, and the founder of the platform was Canadian programmer of Russian origin Vitalik Buterin.
