OMG, or OmiseGO, is a cryptocurrency and blockchain platform that aims to provide financial services for people who don't have access to traditional banking services. It was developed by the same team behind the payment gateway service Omise, and it uses the Ethereum blockchain to provide fast, secure, and low-cost transactions. OMG holders can stake their tokens to participate in the network and earn rewards, while also helping to secure the network through a Proof-of-Stake consensus mechanism. The platform also allows for the creation of decentralised applications and the integration of other blockchain technologies.
