Notably, it provides approximately a 4 times cost benefit, which is a massive saving for projects that rely on random number generation at scale. This economic efficiency is largely due to its optimized gas usage, which minimizes the on-chain transaction cost. In addition to its cost benefits, SecretVRF is also twice as fast as its closest competitor. This speed improvement is critical for applications that require almost real-time randomness, such as gaming, lotteries, and various DeFi protocols. To demonstrate, we have this small video here outlining all of the advantages of SecretVRF vs. its biggest competitor: {% embed url="" %} Short Video from Sean Rad (Dev Rel at the Secret Network Foundation) showing off the advantages of SecretVRF vs competitors. {% endembed %} ### Gas Figures for SecretVRF vs Competitors An example contract call using SecretVRF on Ethereum Sepolia which requests 20 random words is compared for its gas usage. Here, we use the example contracts provided in the documentation of Chainlink. In both cases, response time for Secret VRF is at around 1-2 blocks, so around 10s. #### For calling the VRF for 20 random numbers (less is better): **94k** Gas with Secretpath: [Etherscan Sepolia](https://sepolia.etherscan.io/tx/0x71942fa13e8b9a5d3dc5e587c82e587f5b6e2f4e61ec2bcab253c9ad71710c89) **300k+** Gas for Chainlink VRF with their example project: [Etherscan Sepolia](https://sepolia.etherscan.io/tx/0xdb58ed5326365aa6e611a62fe5f61cc462b504046e9e71c97d889970899e4e45) #### For the Callback (less is better): **55k** gas with Secretpath: [Etherscan Sepolia](https://sepolia.etherscan.io/tx/0xe2c06a5d92b29ae5528adcd5131ed159fdf5c56c828d71e42df5003f84d6b4af\)) **200k+** gas for Chainlink VRF with their example project:[ Etherscan Sepolia](https://sepolia.etherscan.io/tx/0xe70ba65b83ce2f6b1272da9e9097cc48ea2e674457b125e859ebd45286e44f17) In total, we also do not need to pay in special LINK tokens and instead can just pay in the native gas token of the chain (here: Sepolia ETH), which saves you additional costs.

Comparison of SecretVRF via SecretPath (left) vs ChainlinkVRF (right). The total cost difference between both is around 450%.

To summarize, SecretVRF's combination of cost efficiency, speed, and EVM chain compatibility makes it a compelling choice for developers and projects seeking reliable and economical verifiable random functions. Its technical innovations position it as a leader in the space, offering tangible benefits that can significantly enhance the performance and cost-effectiveness of a wide range of blockchain applications. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.scrt.network/secret-network-documentation/confidential-computing-layer/ethereum-evm-developer-toolkit/usecases/vrf/performance-figures-of-secretvrf-vs-competitors.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
