Flare is a new blockchain built for universal connectivity. This master’s thesis briefly presents cryptocurrencies, blockchains, the Ethereum network, and the Ethereum Virtual Machine used in the Flare network. We introduce State Connector, the basis of all interoperability applications built in the Flare network. First such applications are F-Assets and LayerCake. In more detail, we present The Flare Time Series Oracle (FTSO), a decentralized on-chain protocol that gathers price (and data) signals of off-chain assets and submits them to the Flare blockchain. With this, we address the problem of secure and decentralized oracles that can provide reliable data for calculation by other smart contracts. Finally, the governance system of the network is presented in detail, with which the network community (FLR owners) is enabled to make decisions in the co-management of the network.
