Smart Contracts allows the transfer of goods and services without the need for a independent third party. Logic and rules are built into the smart contract that define the permissions and processes associated with a particular agreement and enforce the obligations attached to it. This provides an opportunity to remove middlemen that are traditionally required to interact with physical property or financial service instruments.

## Blockchain Technologies Supporting Smart Contracts ## Blockchain Technologies Supporting Smart Contracts
Two of the most common technologies used are: Some of the most common technologies used are:
- Ethereum - Created to be a blockchain for smart contracts. The smart contracts run in the Ethereum Virtual Machine (EVM), which can be thought of as a decentralized computer. Ethereum smart contracts can be written in Solidity, Serpent or Vyper, which are then compiled to byte-code and fed to the EVM. - Ethereum - Created to be a blockchain for smart contracts.

- Hyperledger - An initiative hosted by the Linux Foundation for private blockchains and tends to be more business-oriented. There are several projects under the Hyperledger name, most of them with Smart Contract capabilities. Ethereum Smart Contracts can be run in Hyperledger too. - Hyperledger - An initiative hosted by the Linux Foundation for private blockchains and tends to be more business-oriented.

- Corda - A new Operating System for Financial Services
There are many other blockchain projects offering (or promising) smart contract capabilities - e.g., EOS, NEO or ICON. They may compete with Ethereum for market adoption (still very low globally) in the future.
