Blockchain

Blockchain is the underlying technology for almost all cryptocurrencies. It is a distributed ledger jointly maintained by decentralized nodes around the world. Blockchain is hailed as "the trust machine", enabling trustless peer-to-peer payments. Blockchain will become the infrastructure for the next generation of the Internet - Web 3.

What Are Flare Data Protocols? A Deep Dive into FTSO and FDC

Flare’s data acquisition mechanism consists of two core protocols: FTSO, or Flare Time Series Oracle, which provides decentralized time-series data such as prices, and Flare Data Connector, or FDC, which verifies the state of external blockchains or systems. By embedding data protocols into the base layer of blockchain, Flare can provide trusted data inputs and cross-chain information access for smart contracts without relying on third-party oracle services.
