A little bit of chitchat 

Recently, Manta published the results of their Dolphin Testnet as a use-case for the open source OpenZL library, which is a Zero-Knowledge-Proof Library for Substrate Builders.This was in the context of a governance discussion to request funding to cover development expenses for this project. According to the post, on the Dolphin Testnet v1, they achieved 60,000+ transactions from 6,000 distinct addresses, accounting for “more private transactions powered by zkSNARK in 3 months than Tornado.cash in one year.” On the v2 of the testnet, their main milestone was improving prover performance from 30 sec to 2 sec. 

Two sister worlds finally connected ⛓️

Acala published an aUSD fungibility palette that will unify the economic infrastructure of Kusama and Polkadot. Thanks to this palette, token holders of $KAR and $KSM can access Acala and Polkadot, and holders of $ACA, and $DOT can seamlessly access Karura and Kusama. 

The palette also has properties for transactions beyond Dotsama, meaning that regardless of where it’s minted (Kaura or Acala), users can transfer it to external chains, like Ethereum via Wormhole, and be received back to either Acala or Karura. 

There will be a quota of tokens that can be transferred to and from Acala and Karura, limiting the risk exposure for both chains. All transfers will happen over a bridge, which is Wormhole, and in the future, it will move over an XCM-powered bridge connecting the relay chains, Kusama and Polkadot. 

Transactions for everyone, everywhere 📱

As interconnected as it is, there’s a link missing in the Dotsama ecosystem. Users operating in different parachains don’t have a unified transaction history that allows them to track their movements easily. This was brought up in a governance proposal by Talisman after gathering user feedback. 

The proposal requests funds to develop a cross-chain transaction history service that would allow users to more easily understand the actions they have taken across different parachains in DotSama. At the same time, Parachains and applications that have a presence across multiple parachains would also have an easier way to show users their relevant actions.

The solution would consist of 3 parts:

A backend service to consume all transactions from all parachains and store the information in a single database

An endpoint to allow data querying

A user interface for end users to look up their transaction history by address

If approved, the team will be able to fully deliver in approximately 12 calendar weeks.

DID is the new gold 💳

There are many lofty goals in the blockchain industry, and the DID (Decentralised Identity) infrastructure is finally gaining steam. Moonbeam is pushing this forward with their recent announcement about the integration with PolkaNameSystem (PNS). 

Thanks to this integration, 8-digit domains are now available using GLMR. These domains (.dot) replace long wallet addresses with human-readable names in Web3. It can be linked to any wallet or contract addresses that Moonbeam owns, generating an aggregated digital identity of Moonbeam.

An IPFS integration in the works will enhance the support to deploy decentralised websites, making searching and browsing in Web3 as friendly as in Web2.

This week’s crowdloans

Maybe it’s summer or maybe it’s the bear market but right now things seem pretty quiet on the parachain auctions.
