Flare Network is a layer-1 blockchain platform designed to solve one of the most significant challenges in the crypto space: interoperability. It enables different blockchains to communicate and share data securely, bringing smart contract functionality to networks that lack them, such as the XRP Ledger.
At its core, Flare utilizes two innovative protocols—the State Connector and the Flare Time Series Oracle (FTSO)—to fetch and verify external blockchain data reliably. It also supports the Ethereum Virtual Machine (EVM), making it easy for developers familiar with Ethereum to build and deploy decentralized applications (dApps) on Flare.
The native token, FLR, plays a vital role in network operations, including staking, governance, and incentivizing data providers.
How Flare Network Was Developed
Flare Network was co-founded by Hugo Philion (CEO), Sean Rowan (CTO), and Naïri Usher (Chief Scientist). The team brought together expertise in financial risk management, machine learning, and quantum computing, laying a strong foundation for the project’s technical ambitions.
The idea for Flare was first introduced in a whitepaper published in August 2020. Initially, the token was named Spark, and the focus was on expanding the utility of networks like XRP Ledger through smart contracts.
In 2019, Flare received early backing from Xpring, Ripple's investment division. A funding round in 2021 raised $11.3 million with support from venture firms and notable angel investors. An updated whitepaper (Flare v2.0) released in December 2022 rebranded Spark to FLR and refined the network’s technical framework.
How Flare Network Works
Flare is a proof-of-stake (PoS) layer-1 blockchain that integrates EVM compatibility, allowing it to run smart contracts and host dApps. Its interoperability features are powered by two core protocols: the State Connector and the FTSO.
The State Connector
The State Connector is Flare’s solution for safe and trustless cross-chain communication. It recreates the state of external blockchains on Flare in a decentralized way. This process involves:
- Request-Commit-Reveal (RCR) Protocol: Users request data from other chains. Attestation providers then verify and attest to this data using Merkle tree proofs.
- Branching Protocol: This mechanism checks whether a majority of attestation providers agree on the data, ensuring consensus and decentralization.
These steps allow Flare to incorporate external blockchain data—such as transaction details or wallet balances—securely into its applications.
Flare Time Series Oracle (FTSO)
Oracles are essential for feeding off-chain data to blockchain networks. Flare’s FTSO is a decentralized oracle system that provides reliable real-world data, like cryptocurrency prices, to dApps on the network.
Data providers in the FTSO ecosystem must stake FLR tokens to participate. If they act maliciously, their staked tokens can be slashed. Users can also delegate FLR to trustworthy providers. Accurate data reporting is rewarded, which incentivizes honesty and improves data reliability.

The Songbird Canary Network
Before new features go live on Flare, they are tested on Songbird—a fully functional canary network similar to Kusama on Polkadot. Launched in 2021, Songbird has its own token (SGB) and governance model, allowing for real-world experimentation in a lower-stakes environment.
Uses of the FLR Token
FLR is a multi-utility token integral to the Flare ecosystem. Its uses include:
- Incentivizing FTSO data providers and delegators
- Paying for transaction fees
- Staking to help secure the network
- Participating in on-chain governance
- Serving as collateral in DeFi applications
FLR Token Distribution
The total supply of FLR is 100 billion tokens. Approximately 58% is allocated to the community through airdrops and rewards. The team, advisors, and early backers hold about 19%, while the remaining 22.5% is reserved for Flare-associated companies and funds.
Key Features of Flare Network
- A layer-1 blockchain focused on cross-chain interoperability.
- Uses the State Connector and FTSO to integrate external data securely.
- EVM-compatible, supporting Ethereum-based dApps and tools.
- FLR token is used for staking, governance, transactions, and incentives.
Frequently Asked Questions
What is the main purpose of Flare Network?
Flare aims to enable interoperability between blockchains. It allows networks without smart contracts to access decentralized functionality and lets developers build dApps that use data from multiple chains.
How does the Flare Time Series Oracle work?
The FTSO uses a decentralized network of data providers who stake FLR tokens to contribute off-chain data. Providers and delegators earn rewards based on accuracy, which helps ensure reliable and tamper-resistant data delivery.
What is Songbird used for?
Songbird is Flare’s canary network. It acts as a testing ground for new upgrades and features before they are deployed on the main Flare blockchain, reducing risks and improving security.
Can I use MetaMask on Flare Network?
Yes. Since Flare is EVM-compatible, you can use MetaMask and other Ethereum-based wallets to interact with dApps on the Flare Network.
How is FLR different from other utility tokens?
FLR is designed specifically to support interoperability and data oracles. It is used for staking, governance, and incentivizing data providers—making it central to both security and functionality on Flare.
Where can I learn more about delegating FLR?
You can delegate FLR to FTSO data providers directly through supported wallets or platforms. This allows you to contribute to network security and earn rewards without running a node yourself. 👉 Get advanced methods for token delegation
