Hello Kylians!

We’re excited to provide a technical update on Kylin and Pichiu’s development endeavor for October 2022. This month’s updates cover all development efforts from Kylin’s dedicated developers led by the Project’s Tech Lead, Sylvain Cormier.

Parallel User Crowdloan rewards: Parallel used XCM without a proxy account, so the process could be fully decentralized. The corresponding Kylin account would generally be accessible with the same private key as the one on Polkadot. In this case, a sovereign account was used. We have re-distributed the rewards directly to the parallel users. We will burn all funds in the parallel’s sovereign account after the 2-year vesting.

Pichiu Airdrop: Airdrop was conducted on October 22, 2022.

A web page was created where 631 correctly signed airdrop requests were signed. Some issues encountered:

* 0 KYL balance ( 100 requests)

* Invalid substrate addresses (14 requests)

* Multiple airdrop requests using the same substrate address * unable to unstake

Suggestions were made to handle the large amounts of support requests better:

* Set of explanatory videos

* User issue board with escalation

Subport: To better manage our support requests, we opted for a user issue triage board where team members have been made admin.

Total issues: 73 issues in 13 days

Distribution Pallet: Work was done to design a higher-level abstraction to help manage payouts. In doing this, it occurred that this pallet was going be closely tied to the democratic process and the manner with which people contribute and benefit. Furthermore, in anticipation of eventual regulatory intervention, we have decided to modify our economic incentives to require modest engagement in the voting process to obtain airdrops.

The distribution pallet will also allow managing the Oracle rewards:

* Parachain reporter registration

* Parachain creates data feed

* Parachain consumes feed

* Rewards for running various types of nodes.

Polkadot LATAM Hackathon: Our first workshop presentation was held on 21st October 2022. Sylvain Cormier, Kylin’s Tech Lead, led the session with his impeccable Spanish. Other members of Kylin’s technical team were present. The overall feedback was great, we also found resources for Web3 Verifiable credentials.

Parachain Oracle MVP: Code deployed for the following on our test network.

* Oracle aggregation buffer vec[int64]

* Mean

* Parachain Reporter registration

* Parachain create data feed * Parachain Consume feed

* Dapp consumes feed

Parachains have been initially approached for insights that could help redact an official proposal on the Polkadot forum. The team is working on smart contract implementation and the oracle system fees.

Application to An application has been filled to be listed on

Online tool/ Internal dev playground: We now have an online tool for exploring our current networks (mainly the ones from the internal-dev-playground), The main purpose of this tool is to help us debug the activity of pallets. Somewhat like but adapted to our needs.

Kylin toolbox: Set of tools to manage the node and interact with the oracle system https://github. com/Kylin-Network/kylin-toolbox We used this tool to open a channel with Bifrost on Rococo

Rococo and Kusama upgrades:

* Polkadot client version 0.9.25 to 0.9.26

* Polkadot client version 0.9.26 to 0.9.27

* Polkadot client version 0.9.27 to 0.9.28

* Polkadot client version 0.9.28 to 0.9.29

Kylin Network strives to be a composable and configurable multi-level oracle infrastructure built as a Polkadot parachain, for the democratization and delivery of accurate data on time, at a reliably low cost. Kylin hopes to offer a way for chain-agnostic APIs to serve data according to service level agreements (SLA) that the consumers of this data will be aware of.

Data source compatibility beyond price feeds will bootstrap a free data market. This will allow market demand to determine the direction of the innovation of a feed, its price, and supply. With dynamic NFTs & SFTs, Kylin’s ongoing development will innovatively tokenize data streams that democratically will be accepted on the Kylin Network.
