[WIP] KVService: upload chains onto Arweave

[nykma]

Description

KVService is a Zero-Trust Key-Value storage space for all users who has a elliptic curve based asymmetric keypair (aka Avatar.

• Introduction of KVService

It is designed as a git-like patch chain, each link on the chain is created and signed by user, so any third-party cannot modify / falsify it.

Currently we’ve impl it in a zero-trust way, but we still want to make it more decentralized, more neutral, by putting user’s link onto a storage provider like Arweave.

By uploading all KVChain onto Arweave, we can reach more usability and data transparency improvement.

Expected outcomes

• You may write a separated worker to do async upload job.
• You need to record Arweave’s ObjectID-ish into database after a successfully uploading.
• Arweave’s ObjectID should be returned in query API (if target record has one)
• Take a look at ProofService’s current impl as an example.
• Don’t forget unit tests.

Skills required

• Rust
• Basic knowledge of Arweave usage

Hi, I am a current fourth-year university student currently planning to participate in the OSPP. Since I have some previous experience in blockchain trading and self-learning experience, I am very interested in this project in your community and I am currently reading some source code of the project and writing my project application, I hope I can successfully participate in this project this year.
