Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

DATUM

Datum is a cross-chain permissionless oracle protocol for your smart contracts built on top of Optimism's newly created OP stack chains and Superchain.

DATUM CONTRACTS

Smart Contracts needs Off-Chain data to build useful applications and data availability is an integral part of any Op stack Chain. With DATUM , now you can get off chain data from Chainlink and UMA oracles straight to your chains in seconds and minimal setup of Oracle Nodes.

There are endless possiblities of dApps which can be built with the help of Data provided oracles like Predictions Markets , Insurance Claims , DEFI Appilcations and a lot more.

We are Supporting 5 types of Oracles currently :-

Price Oracles - Get price info on chain with Chainlink Price Feeds for multiple coin pairs.

VRF - Verifiable randomness with Chainlink VRFv2 , to get random words and uints to build lottery applications and other purposes

Optimistic Oracle V2 - Off Chain data like prices , YES OR NO queries , Valuations and indexes and lot more

Optimistic Oracle V3 - The OOV3 is an oracle for arbitrary off-chain data which leverages an interactive escalation game between asserters and disputers and is secured by economic incentives.

API Oracle - Any sort of API GET calls , to fetch off chain data, like Sports and Weather info directly on Chain.

The Data is obtained in a decentralized manner via Chainlink's Oracle network and UMA's system.

More information about the contracts and their usage can be found in our docs: https://datum.gitbook.io/datum/
