Project Overview 📄
Canyon is designed to be a permanent storage network built on Substrate, which records the hashes of files on-chain and stores the files off-chain. By blending PoS and a probabilistic proof-of-storage scheme inspired by Arweave, Canyon greatly reduces the barriers to entry for miners, who are incentivized to store as much data as possible for the rewards. Another focus of canyon is also to build a truly useful data sharing system, providing the high availability of data access in the protocol level.
This grant mainly concentrates on the consensus part of canyon network, specifically the PoA consensus will be implemented. Aside from the core consensus algorithm, some indispensable basic components/tools will be built at the same time. Refer to the consensus section of white paper for more information. We'll also keep updating the technical details in the paper when necessary once more progress is made.
There is no doubt that the infrastructure, providing a secure, highly available, low-cost, and easy-to-use decentralized data access service, will be an essential part of Web3.0 applications. Canyon network is created in such a background and tries to mitigate the known problems in the existing decentralized platforms, with a principle of lightweight storage consensus and highly usable protocol level data retrieval mechanism in mind.

|0b.||Documentation||We will provide both inline documentation of the code and a basic tutorial that explains how a user can spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works.|
|0c.||Testing Guide||Core functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.|
|0d.||Docker||We will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.|
|0e.||Article||We will publish an article that explains the implementaion details of PoA consensus. We will update our paper with more SPoRA technical details and analysis.|
|1.||Node: ||We will create a crate that will provides two RPCs: |
|2.||Node: ||We will create a crate that will provide the feature of persistent transaction data storage on the top of offchain storage.|
|3.||Node: ||We will create a crate that will implement the core algorithm of PoA illustrated in the white paper. This crate will also implement the function of inherent data provider to inject a |
|4.||Node: ||We will create a pallet that will implement |
|5.||Rust CLI: ||We will extend canyon-cli by adding two new commands: |
fn submit(value: Bytes) -> Result<H256>
- user can send arbitray data bytes(<=10MiB) to the node, the chunk root will be returned once stored successfully.
fn retrieve(key: Bytes) -> Result<Option<Bytes>>
- user can retrieve the data(<=10MiB) directly using this PRC, the key is the chunk root of the data.
The short term plans:
- Implement the pricing strategy for the
storetransaction in the context of paying once for the perpetual storage.
- Support uploading/retrieving data chunks for large files(>10MiB).
- Implement transaction data sync between the multiple nodes.
- A comprehensive design for Staking system on the top of NPOS, taking the factor of validator that also behaves a storage service provider into account.
- Improve and audit the code to make it production-ready.
- Build client tools for storing data onto the network easily, especially the web UI.
- Build a network data explorer that shows the distribution of data in network nodes.
The long term plans:
- Do more researches and develop a more effective data sharing mechanism, rendering canyon network a highly useable data retrieval platform.
- Foster more web3.0 applications using the decentralized storage infrastructure provided by canyon network.
Additional Information ➕
The earlier successful W3F grant name is
Canyon Network, which is mainly about the early research problems on the decentralized storage network and can be considered the starting point of works afterward.
