Parallel

1, Heiko overline Kusama network

We successfully won Kusama’s 10th Parachain slot in early October. Currently, Heiko is steadily producing blocks, and we are preparing for the launch of Heiko’s mainnet. This will include several stages to ensure that every deployment from basic functions to the complete platform including necessary deployment, runtime upgrades, testing, and technical certification is stable. Stay tuned, we will announce more information soon!

The deployment is currently in progress, including scanner features, unlocking customers, application mode, and execution time upgrades. After Heiko goes online on the Kusama network, we will start the community distribution of HKO as a way to thank the community members who support us in the Heiko crowdloan. The unlocking is about to begin, and users can apply for their own tokens and use them on our platform.

2. Announced participation in Polkadot Parachain Auction

We are about to participate in Polkadot’s first batch of Parachain Auctions and are actively preparing for crowdloan. Parallel’s goal is to collect 20 million DOTs. We hope that the community can strongly support our parachain auction, because it is essential for us to go online on the Polkadot network. Click to watch Parallel founder and CEO Yu Bo explain the reward mechanism for participating in our crowdloan: https://youtu.be/fZmkUTID1OI

Our whitelist has opened registration, and currently more than 10,000 users have expressed their interest in participating. Register here: https://parallel.fi/polkadot/parachain-auction-waitlist.html

Released Auction Loan products. Users can participate in Kusama and Polkadot’s Crowdloan through Auction Loan. The importance of this product to the ecology is embodied in that it increases the diversity of contributors and helps the project obtain the required liquidity when bidding on parallel chain card slots. We have also reached cooperation with the largest builders in the Polkadot ecology to help the project party succeed in bidding for the card slot to a greater extent, and to better motivate the community. Currently confirmed partners include: Astar, Litentry, Manta Network

In addition, our products release liquidity in advance through cDOT/cKSM. Every DOT/KSM contributed through the Parallel platform can allow users to obtain derivative assets and use them in our Money Market. Using Parallel to participate in Kusama and Polkadot’s crowdloan will give users a strong enough motivation, because they will get extra rewards on top of the basic rewards.

The Money Market product has been released on October 28, 2021. Community testing and planning will begin soon. We will adopt a phased approach for testing, which means that at the beginning we only allow a small amount of start-up funds, and through these funds, we will check for vulnerabilities and optimize stability in the next few weeks, and then gradually increase The amount of funds. Our users can test the currency market and pledge products and provide us with feedback.

PARA’s token economic model-we are designing our incentive structure and the community distribution model of native tokens (details will be announced in the next few days).

There are suitable candidates for the three key positions we are hiring: financial manager, senior QA engineer, marketing consultant!

SegFault and Halborn are auditing us, and we are currently proceeding smoothly. We are actively correcting and improving problems based on the previous audit report.

3. The next step

October 2021 is a fruitful month, we won the Kusama Parachain card slot. We hope to continue to maintain this good momentum in the next Polkadot auction. Please pay attention to the announcement about Polkadot crowdloans’ early contribution and participation methods. Additional rewards will be distributed to our community members through our Auction Loan platform. Stay tuned!
