Abstract

Using AO’s computing power to undertake Ethereum’s computing tasks

Motivation

Ethereum, the largest ecosystem, as knowns, there are still many shortcomings, especially the computations due to system limitations. And AO currently is the top leader in this decentralized calculations.

So, we combine the advantages of both, establish a connection. For the heavy tasks that require a lot of calculations on Ethereum, we complete them on AO, and return the calculation results to Ethereum.

This will have a very large influence not only for Ethereum, but also for AO ecosystem.

Principles and Feasibility

Principles and Feasibility

To connect the Ethereum and AO system, first we need a bridge. For security reasons, we use Chainlink to help us realize the bridge.

Chainlink can connect resources outside of Ethereum and write back to Ethereum.

During implementation, firstly, user initiates an on-chain request on Ethereum, and here, we may need a relayer whose role is to calculate and store the calculation results on AO in advance, and the source data come from the request on Ethereum. Then Chainlink obtains the AO calculation results based on the parameters of request and put the result back to the Ethereum.

Rough flowchat shows as following:

Another Infrastructure

In order to make the same calculation results of both system, AO needs to have functions related to Ethereum, especially the Elliptic Curve functions, so that it can seamlessly undertake the computing tasks of Ethereum.

We have checked the modules currently supported by AOS, but there is far from enough for Ethereum.

So the infrastructure need to be built simultaneously.

We summarize the main functions that Ethereum ecosystems need:

Required Resources

If we have partners familiar with the LUA language joining us, it will greatly help our project.

Yes, bridges to other networks from AO is very exciting! Love the project, what are your thoughts on a trustless bridge? Is multi-sig required?

[tokenlin]

Hi, Wilson, this a good question. Building a trustless bridge is our first priority.

In this protocol, there are two important roles. One is the relayers that helps obtain information from Ethereum and run it on AO, finally, write it back to Ethereum through the Oracle, and the other is the Oracle that reads the results from the AO network.

Anyone can become a relayer without any restrictions, and can get certain rewards after completing tasks. For the Oracle, we choose Chainlink Oracle. The Oracle will check whether the returned results are settled according to the parameters of the task. The bridge uses cryptographic primitives to validate information passed between blockchains . So, there is no need for multi-sig for both.

This is a great idea! We need to first implement some functions on AO that already exist on Ethereum. At the same time, these implemented functions can also serve as part of the infrastructure for other projects built on AO, which is truly exciting!
