What Is Spark (FLR) and the Flare Network?

If you wanted to reach the value of every blockchain, that would be impossible. The value of over 65% blockchain dApps is locked and that’s a challenge to surpass for projects like Flare network. Flare unlocks additional versatility for cryptos, touching no security properties. This article is a thorough guide to answer questions like how does the Flare network operates and What is flare network spark.

What is the Flare network?

Commonly mentioned in the form of FLR abbreviation address, Flare is the first Turing-complete Federated Byzantine Agreement (FBA) network in the world. The Avalanche consensus mechanism is used by nodes, with a key adaption to the FBA consensus topology. 

As a consensus topology, FBA accomplishes safety without depending on economic incentives, which might conflict with high-value and high-risk use-cases. The Flare Network makes use of the Ethereum Virtual Machine (EVM), allowing it to perform Turing complete smart contracts. A special  Flare Virtual Machine, almost identical to EVM, converts complex smart contract codes into manageable instructions. Thus creating a decentralized applications ecosystem.

What is Spark?

Spark is the native token of the Flare Network cryptocurrency ecosystem, which is necessary for functioning smart contracts for XRP, but on a different network. The Ethereum blockchain ecosystem, for example, also has smart contracts, but they function within the blockchain itself.

Flare Network benefits

A significant portion of the value in blockchain networks cannot presently be used in a trustless way via smart contracts. According to the project, smart contract systems based on the Proof-of-Stake (PoS) consensus mechanism or its derivatives (e.g., DPoS) would suffer serious security challenges in the future.

The safety of PoS-based networks is derived from their native tokens, according to the Flare team. In this case, they adopt a procedure in which validators store bitcoin in their wallets in order to validate transactions and blocks in return for staking rewards. While this keeps the network secure, it does not provide safe alternative use-cases.

Assume that lending ETH via a DeFi protocol gives a 30% annual percentage return (APY) while staking the same token only offers a 5% APY. In such instances, most customers would choose the first option because it offers far higher rewards

Flare Finance ecosystem

Flare Finance has to be the most obvious answer to where to buy Flare token crypto. Launching together with Flare Network, it will become the first decentralized DeFi platform for XRP owners. A unique governance structure will create an ecosystem where every holder has input in its future. This project is unique compared to alternatives because it provides a list of financial products/tools:


FlareX allows Flare Network users to trade currencies and earn passive income by supplying liquidity. It’s a typical decentralized exchange leveraging liquidity pools and an automated market-making model. The community can use FlareX to stake some tokens and make passive income on their stake.


Flare wrap is a bridging solution to cut off excessive transactions and fees. It simplifies bridging to the Flare Network. By avoiding the exchanging process for many currencies, FlareWrap allows users to make extra money.


Community members can generate yield by several stacking pools. For example, users can stake XRP and other available currencies to make passive income. 


A decentralized mining pool where users can leverage their computing capabilities to mine Bitcoin and Ethereum. The platform automatically turns earned tokens into FLR (Spark), so users can earn interest on the native tokens. 


A platform for decentralized loans. The main requirement of issuing the loan is 120% of collateral, which will be used to repay the loan in terms of any delays. Compared to other platforms, the collateral is pretty low. For example, a Compound requires 150% or more for collateral. Synthetix crypto platform won’t approve collateral lower than 500% for some assets.


FlareMutual makes it possible to secure the projects based on Flare Network. If any project has breaches and malfunctions due to a poor-designed smart contract, FlareMutual is a way to protect the project. Share the risk with other users by paying them a share of the yield.

After the launch of Flare Network, Flare Finance has three types of its tokens based on the Flare network coin. Users need the derivatives for managing the projects, paying commissions, and distributing fees. Here is essential information related to tokens:

  1. YieldFlare (YFLR). The key token of Flare Finance that will be used in all the mentioned DeFi services. However, its primary function is paying commissions. It is also crucial for governance as 1 YFLR is equal to 1 vote when choosing the updates of the structure. Flare Finance will issue 110 million YieldFlare tokens in total.
  2. YieldFin (YFIN). The critical function of this token is governance. One YFIN token is equal to 10,000 votes. Once used for voting, they will not disappear. The total amount of YieldFin tokens is 11,000.
  3. YieldMine (YMIN). The platform will use this token to reward users that provide their computing power on the FlairMine product. Flare Finance can give out up to 100,000 of them daily, and there are no limits on the total amount.

What are Spark tokens, and how do they work?

Spark is the Flare Network's native token, aimed to provide smart contract capability similar to XRP but on a different blockchain. As a native Flare blockchain cryptocurrency, Spark is collateral to issue different F-assets within decentralized applications. Spark also provides data provision, governance, and spam prevention leveraging transaction fees within the Flare network. For example, users can vote on the prices of F-assets in the FTSO. You can check the official website featuring the list of Flare supporting exchanges.

The initial supply of FLR is 100 billion tokens. Flare network dedicated 45% of the total supply to eligible owners of XRP crypto except for the wallets with the address of Ripple Labs. The conditions include accruing Spark at a 1:1 ratio, but the chances of the ratio being closer to 2:1 are pretty high.

At the moment of writing the article, FLR coin crypto price flats around $0.76 per token. You can see a detailed 30-day price chart below.

Flare network and Ripple (XRP)

Flare Network is a distributed blockchain network that uses the Federated Byzantine Agreement-based (FBA) Avalanche consensus process.

Unlike the XRP Ledger (XRPL), Flare incorporates the Ethereum Virtual Machine (EVM) and enables smart contracts natively. Most significantly, Flare may interact with other chains to extend the functionality of their networks and native currencies, such as through incorporating smart contracts.

Flare is useful for Ripple because it can serve as a bridge between the XRP Ledger and a smart contract platform such as Ethereum. As a result, XRP will have smart contract capability, allowing it to be used for dApps, DeFi solutions, and NFTs.

FXRP coin and nature of F-assets

FXRP is one of 4 F-assets available on the Flare Network. By definition, it’s just a representation of an XRP cryptocurrency on the mentioned network. Bringing one of the cryptocurrencies (XRP, XLM, DOGO, or LTC) to the Flare is possible due to the process of minting. 

For example, any XRP holder (originator) can use FXRP to transmit the cryptocurrency to a group of addresses (agents) on Ripple's network. Smart contracts will be used by agents to mint the originating FXRP on Flare. The freshly created FXRP has a 1:1 value peg with XRP and is secured by Spark tokens.

When a user exchanges FXRP for XRP, he returns the previous token to the Flare smart contract. Then, agents send the same amount of XRP to the user's address on the XRP Ledger. If the agents fail to transmit the XRP to the user within a certain time frame, the network will reward him for the value of his XRP holdings as well as an additional quantity of coins to cover the transaction costs for repurchasing the digital asset.

The most crucial characteristic of FXRP and other interoperability protocols built on Flare is that the entire process of bridging two chains (and moving the native token of one to the other) is decentralized.

After minting tokens, the agents' Spark is locked away in a smart spark FLR contract. When an originator exchanges their FXRP for XRP, the network returns the agent's collateral to him. Originators pay a creation fee to agents in XRP in return for providing collateral for token minting, which incentivizes the latter parties to sustain the network. Flare, on the other hand, punishes agents for negative behavior.

When an originator converts FXRP to XRP, the network grants the agent two deadlines. If he only meets the second deadline and not the first, he receives his collateral back with a minor penalty cost. If the agent fails to meet the second deadline, Flare will consider it a redemption failure, in which the network burns half of his Spark collateral and returns the other half to him. Simultaneously, the originator earns 1% more after redeeming his XRP to offset the expenses of token buybacks.

Closing thoughts

Flare combines the value of non-Turing complete coins with the transformational potential of smart contracts on a network that can scale in terms of both value and transaction throughput. If the article was helpful and you want to discover even more info like this, check out our academy section.
