With Axiom’s public launch, we’re excited to see more projects working to empower dApps with trustless access to historical on-chain data. With a similar mission and demo apps, some have asked how Relic and Axiom differ and which use cases are better served by each project. …

We just open-sourced DailyGasFloor, a fully on-chain, decentralized, and incentive-compatible gas price oracle built on Relic Protocol. This post will dig into how it’s built and how it could be adapted for other price feeds. How it works Rounds Daily Gas Floor (DGF) divides time into rounds consisting of 8192 blocks (roughly 27 hours)…

After reading through Part I, we should now know a bit better what the problems are with airdrops and why it would be nice to use historical state from a project such as Relic, let’s get into exactly how to implement this. This example will go through how to build…

Airdrops are pretty simple. At their core the goal is just to send tokens to users based on some criteria. But how is this actually implemented in practice? well, it can get a bit complicated. …

Our previous post gave a high-level overview of how Relic Protocol enables smart contracts to trustlessly access all of Ethereum’s historical state. As promised, this follow-up post will give more details about our scaling approach, including the zk-SNARK circuits, proof system, and on-chain verifier. Motivation We’ll first give some motivation for…

Non-Fungible Tokens (NFTs) are made on blockchains, which means they are on-chain, right? Not so fast: it turns out it is a lot more complicated than that. Even if they are smart contracts, most NFTs rely on things outside of the blockchain. …

The idea behind Relic is simple: smart contracts should be able to securely access any data ever pushed to Ethereum. After all, we can easily access the history on Etherscan, or with our own archive node, so why not from dApps? While the basic idea is simple, there’s a lot…

Currently, smart contracts on Ethereum have surprisingly limited access to the blockchain’s data. We are changing that. Historical Data The Ethereum blockchain contains over 15 million blocks, in which over 1.7 billion transactions have occurred and over 200 million accounts have been created. …
