Enshrined Data Protocols

Flare implements native data protocols directly at the network level. These are not added-on oracle systems but built into the base protocol of the blockchain. This structural design enables smart contracts to access decentralized data feeds and verified external information without relying on off-chain infrastructure or third-party services.

The Flare Time Series Oracle (FTSO) is responsible for delivering decentralized and high-frequency data, such as price feeds, which are essential for many decentralized applications. The FTSO gathers data from independent providers who compete to submit the most accurate information. Providers are rewarded based on their accuracy, and token holders can delegate their voting power to these providers, earning a share of the rewards.

The Flare Data Connector (FDC) is the protocol that enables smart contracts on Flare to safely access data from other blockchains and from Web2 APIs. This includes verifying whether a certain transaction happened on another chain or retrieving information like user credentials from traditional web services. The FDC uses a consensus mechanism to validate that the data is correct before making it available on-chain.

These protocols inherit the same level of decentralization and security as the Flare blockchain itself. They are not dependent on individual data sources or centralized intermediaries. This reduces the attack surface and improves the resilience of any application that uses them.

Ethereum Virtual Machine Compatibility

Flare is fully compatible with the Ethereum Virtual Machine (EVM), which means developers can deploy Solidity-based smart contracts and reuse existing tools and codebases built for Ethereum. This compatibility simplifies onboarding and lowers technical barriers for developers already familiar with the Ethereum ecosystem.

By supporting the same development environment, Flare allows for quick migration or replication of Ethereum decentralized applications (dApps). Developers can use familiar tools like Remix, Hardhat, and Truffle to write, test, and deploy contracts on Flare without significant modifications.

EVM compatibility also enables interaction with standard Ethereum token contracts, such as ERC-20 and ERC-721. This ensures that assets issued on Flare can conform to widely recognized formats, making them easier to integrate with wallets, exchanges, and DeFi platforms.

One of the advantages of combining EVM support with Flare’s native data protocols is that developers gain access to both computation and data logic in one place. This reduces the need for bridges, relays, or manual input when creating applications that need to respond to external or cross-chain conditions.

EVM support also opens the door for integrations with Ethereum Layer 2 solutions and interoperability protocols. Applications can be designed to operate across networks, with assets and data moving fluidly between chains while leveraging the security and cost-efficiency of Flare.

Highlights
