Tellor Crypto: A Decentralized Oracle for Ethereum DApps

If you are interested in decentralized finance (DeFi) and smart contracts, you might have heard of the term “oracle”. Oracles are services that provide external data to smart contracts, such as prices, weather, sports scores, etc. However, not all oracles are created equal. Some are centralized and prone to manipulation, while others are decentralized and trustless. In this blog post, we will introduce you to Tellor, a decentralized oracle network that connects smart contracts on Ethereum to real-world data in a secure and transparent way.

What is Tellor?

Tellor is a blockchain-based decentralized oracle network that was launched in 2019. It allows smart contracts on Ethereum to access any off-chain data, such as cryptocurrency prices, stock prices, exchange rates, etc. Tellor uses its native token, TRB, to incentivize data providers (called reporters) to submit valid data on-chain, and to penalize them for submitting invalid data. Reporters compete to mine TRB by solving proof-of-work puzzles and providing data requested by users. Users can also tip reporters with TRB to prioritize their requests.

Tellor aims to provide a reliable and robust oracle solution for Ethereum DApps, especially those in the DeFi sector. Unlike some other oracles that rely on trusted third parties or centralized servers, Tellor is fully decentralized and permissionless. Anyone can become a reporter or a user of Tellor, without any verification or registration process. Moreover, Tellor is flexible and adaptable, as it can support any type of data request in any format.

How does Tellor work?

Tellor works by following a simple protocol:

  • Users request data by sending a query and a TRB fee to the Tellor smart contract.
  • Reporters monitor the queries and select the ones they want to answer.
  • Reporters mine TRB by solving proof-of-work puzzles and submitting data along with their solutions.
  • The first five reporters to submit valid solutions form a consensus and update the data on-chain.
  • The reporters receive the TRB fees and rewards for their work.
  • Users can access the data from the Tellor smart contract or from the Tellor website.

However, what if a reporter submits invalid or inaccurate data? This is where Tellor’s dispute mechanism comes in. Tellor allows anyone to challenge a data submission by staking TRB and providing evidence of its invalidity. The challenge is then voted on by a jury of TRB holders, who decide whether to accept or reject it. If the challenge is accepted, the reporter’s stake is slashed and distributed among the challenger and the jury. If the challenge is rejected, the challenger’s stake is slashed and distributed among the reporter and the jury.

This way, Tellor ensures that reporters have an incentive to provide honest and accurate data, while also giving users a way to verify and dispute the data if needed.

Why use Tellor?

Tellor offers several advantages over other oracle solutions, such as:

  • Decentralization: Tellor does not rely on any centralized authority or intermediary to provide data. It is powered by a network of independent reporters who are incentivized by TRB tokens.
  • Security: Tellor uses proof-of-work and staking mechanisms to secure its network and prevent malicious attacks. It also allows users to dispute and verify the data on-chain.
  • Flexibility: Tellor can support any type of data request in any format. Users can specify their own data sources and parameters for their queries.
  • Transparency: Tellor records all the data submissions and disputes on the Ethereum blockchain, making them publicly visible and auditable.
  • Compatibility: Tellor is compatible with any Ethereum smart contract or DApp that needs external data. It also supports interoperability with other blockchains through bridges.

How to get involved with Tellor?

If you are interested in using or contributing to Tellor, there are several ways you can get involved:

  • Buy TRB tokens: You can buy TRB tokens from various exchanges or from the Tellor website. You can use TRB tokens to request data, tip reporters, stake for disputes, vote on disputes, or simply hold them as an investment.
  • Become a reporter: You can become a reporter by running the Tellor miner software on your computer and connecting your wallet. You will need some TRB tokens to stake as collateral and some ETH to pay for gas fees. You can then start mining TRB by providing data requested by users.
  • Become a user: You can become a user by integrating Tellor into your smart contract or DApp. You will need some TRB tokens to pay for data requests and some ETH to pay for gas fees. You can then access the data from the Tellor smart contract or from the Tellor website.
  • Become a juror: You can become a juror by holding TRB tokens in your wallet and voting on disputes. You will receive a portion of the slashed stake as a reward for your participation.
  • Join the community: You can join the Tellor community by following their social media channels, joining their Discord server, or reading their blog. You can also contribute to their development by submitting issues or pull requests on their GitHub repository.

Conclusion

Tellor is a decentralized oracle network that connects smart contracts on Ethereum to external data in a secure and transparent way. It uses its native token, TRB, to incentivize data providers and to enable data verification and dispute resolution. It is designed for Ethereum DApps, especially those in the DeFi sector, that need reliable and robust off-chain data. Tellor is a promising project that aims to solve the oracle problem and to enhance the functionality and usability of smart contracts. If you are interested in Tellor, you can visit their website or follow them on their social media channels to learn more.
