Welcome to the #18 edition of Rust in Blockchain, the hypest newsletter about the hypest tech. Previous: #17.
It’s a good time right now to be patient and cautious with the health of our blockchains. Oh, and also our frail human bodies.
Anyway, on to the ribbles! (That’s Rust-in-Blockchain Nibbles, I guess)
This month, Oasis, a blockchain that runs Rust contracts on WASM inside secure enclaves, launched their mainnet. The Ethereum 2 beacon chain also went live. NEAR has a whiteboard video with the Sigma Prime team, who develops Lighthouse, the Eth2 client in Rust. It introduces the network layer in Eth2, how the nodes communicate, and more. Congrats to both the Oasis and Lighthouse teams!
From projects we typically cover, Parity and NEAR released many good videos this month, which are great resources for developers to learn programming blockchain.
Brian, one of the RiB editors, has continued documenting his experiments with Rust-based smart contract platforms, this month publishing his initial impressions of Substrate and Ink. We hope to bring more of this kind of content to the RiB community in the future.
We open-sourced ribbot, the script that helps us generate progress reports from GitHub repos. It currently has no documentation or readability. If you ever wonder why the stats we publish for your project seem wrong, the answer is somewhere in here. We plan to slowly refactor it and hope it can be a general purpose tool program that is useful for other projects.
RiB has recently received requests from multiple organizations to advertise in the newsletter or the website. As RiB is always a community project, we do not want to make any decisions without open discussion first. We ask your thoughts about how to handle advertising or sponsored content in RiB. Please reply to this newsletter email directly, or discuss on the Telegram group.
RiB needs help to keep up with Rust blockchain projects. If you follow a particular project, or otherwise find information that is beneficial to the Rust & blockchain community, please contribute to the next issue by submitting a PR to the #19 draft.
Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
The team recently gave a talk at zkSummit6: zkSummit6: arkworks: A Rust Ecosystem for zkSNARKs – Pratyush Mishra.
The best entry point for understanding the code as of now
appears to be the
which defines generic traits for zkSNARKS.
This work is an extension of that done for the previously-published Zexe: Enabling Decentralized Private Computation.
