Oracles are among the essential and prominent blockchain technologies that keep the crypto industry operating.
The primary purpose is to provide real-world and real-time data to distributed ledger technology and smart contracts because these technologies cannot gather data independently.
Decentralized oracles were created to respond to the oracle difficulties affecting the blockchain environment. Decentralized oracles, also known as decentralized oracle networks (DONs), are a collection of autonomous nodes on a blockchain that communicate with one another.
Nodes and oracles of decentralized oracle communities independently produce and generate information onto the chain from an off-chain supply. The system then aggregates the data to determine reality's deterministic value for that level of knowledge.
Problems caused due to oracles are solved using decentralized oracles. Despite the most recent crypto-related crisis, Oracle cryptocurrency projects are a popular investment option. This blog will take you through the details of the Top 5 Decentralized Oracle Crypto Projects.
Band Protocol
Band Protocol, without any second thought, is one of the renowned and well-known oracles to have a look at. Operating on popular blockchains like Ethereum and Cosmos, this decentralized oracle protocol offers real-world data to dApps and smart contracts.
It is a part, or in other words, an element of the Cosmos Network as Band Protocol was created using the Cosmos SDK. Also, on the other hand, there are chances that it might function with different blockchains all because of Cosmo's Inter Blockchain Communication (IBC) Protocol.
Band Protocol takes into account the DeFi industry's rapid growth and the dApps demands for fast and trustworthy data delivery. Using the native BAND tokens, the Band Protocol lets network members agree on data verification. The tokens are used as collateral during the verification process.
The Band Protocol offers rewards to its Validators for responding to requests for outside data, contributing to consensus, and building new blocks using its native BAND token.
QED
QED is a protocol that is built on the Delphi Oracle. With its solid economic base, this decentralized oracle is designed to fill the gap in the crypto industry. It connects many blockchains, off-chain data sources, and innovative contract platforms. QED is the best alternative protocol because of its security, efficiency, durability, and complete decentralization.
When compared to similar oracle protocols such as Chainlink, which has an avg. refresh rate of 120s, the 0.5s data refresh rate of this oracle is excellent and promises potential. As a result, it allows more decentralized applications with fewer restrictions on data finality and faster refresh rates. On WAX Blockchain, DelphiOracle is the most commonly used oracle on this blockchain, having been utilized around 60,000 times.
The QED oracle protocol is dependable and robust. For example, the death spiral of systems such as Terra Luna was predicted by QED, which has always used external collateral and has never been dependent on a system token for collateral.
API3
The API3 project successfully addresses the oracle concern by creating decentralized APIs that make it easy for blockchains to go through off-chain data.
Creating powerful decentralized apps that support the expansion of DeFi, it's a relatively simple and dependable solution that does not require mediators. These dAPIs straightly come from the blockchain.
Combining several operators makes it possible for API providers to directly host oracle nodes, promoting a direct link between the blockchain and data sources. dAPIs offer more security because they deliver precise data and safeguard API providers from harmful third parties.
Decentralized Oracle Service Network (DOS)
DOS is another oracle that has performed successfully in supplying and providing up-to-date information to blockchain-based systems. The Decentralized Oracle Service Network (DOS), a Layer-2 protocol, is built for horizontal scalability.
The number of nodes in the network is increased to increase the oracle protocol's processing power. Additionally, DOS has also shown that its security is resistant to cyberattacks. The other is the crypto-economic model.
Decentralized Information Asset (DIA)
The Decentralized Information Asset (DIA) platform offers users a mechanism to collect, verify, and distribute valuable data. The open-source program is owned by a non-profit organization based in Switzerland.
This oracle platform aims to close the gap between blockchain and the natural world by offering reliable, real-time data that powers DeFi.
Similar to the Band Protocol, it rewards active community participation with cryptocurrency incentives. In addition, this Oracle platform promotes transparency by making its data feeds open-source and easily accessible for audits if necessary. Also, DIA has an incredible potential for the DeFi ecosystem's upcoming exponential growth.
Conclusion
A Decentralized Oracle is a multi-layered, cross-platform Oracle solution that can handle virtually any blockchain and deliver data to any decentralized ecosystem that needs it.
The key to gaining access to the future that smart contracts hold for us is found in blockchain oracles. We require access to a variety of trustworthy facts if smart contracts are to be the superior form of agreement.
