I'm going to start documenting the progress / providing updates on the development of zkUSD, an algorithmic stablecoin native to the Mina blockchain. The protocol is being developed here: github.com/orgs/zkUSD-Pro… Thanks for the suggestion sMgT!

Charlie Mack (@mackcee) 's Twitter Profile Photo

Last week was spent on the redesign of our oracle price feed. With our previous design the zkUSD protocol would account for just under half of the current network capacity for zkApp transactions. Which would be insane. We are now aggregating oracle prices off chain and creating

Another big refactor this week to tackle Mina network hardfork verification key obsolescence - what a mouthful. We had been deploying vault contracts to the token accounts of our users, but this means that in the event of a network upgrade that bricks the verification keys, we

No big sexy update. Our main focus is on integration testing and building out the frontend. The frontend is almost done and most of the abstractions and structure for managing parallel transaction lifecycles on Mina is complete, paving the way for an extensive test suite.

Charlie Mack (@mackcee) 's Twitter Profile Photo

One really interesting area of our integration tests has been building out a financial risk model in python that maps a number of different scenarios across a matrix of different risk parameters. The goal is to see how the protocol performs and recovers under extreme price drop

Developing on L1 Mina can be a challenge. Especially managing state for zkApps. I've written a blog post that might help some people trying the navigate the trickiness: mackcee.substack.com/p/overcoming-m…

For the past couple of weeks we have been focused on: - Extending our financial risk model to simulate protocol recovery mechanisms in the event of black swans - Writing the Whitepaper - Building out the landing page of website - Improving the CI/CD for our infra / setting

We've just created our official protocol X account. I'll keep providing informal updates on this account but for more official communication, follow Fizk Protocol (zkUSD).

We just hooked up our first oracles on devnet! We are now getting real prices. Check it out. devnet.fizk.xyz/app/connect If anyone is interested in running an oracle on devnet then please reach out.

Hey everyone πŸ‘‹ It’s been a while since my last update. Since the high intensity development period up to mid march, things have relatively slowed in terms of tangible deliverables. - We have made some great progress on proof based governance that will begin life as an

We have just released a CLI tool for interacting with the Fizk protocol from the terminal. Its fully decentralised: 1) Client side proving for oracle price and tx proofs 2) Vault state built from contract events Check it out: npmjs.com/package/@zkusd…

We’ve just completed implementation of a novel self-governing DAO architecture for the Fizk Protocol. This system supports holistic protocol governance, from adjusting risk parameters to upgrading the verification keys of smart contracts. It represents an important step toward
