The key word of Polkadot Ecology in August is "connecting the past and the future". On the one hand, the first batch of connected parachain projects are getting better and better, and core functions have been gradually launched. Karura launched mortgage KSM to borrow kUSD, KSM/kUSD liquidity incentives, etc.; Moonriver deployed its first project; Khala launched the Ethereum cross-chain bridge and governance mechanism; Bifrsot launched assets and governance modules, etc.
On the other hand, with the second batch of Kusama auctions imminent (starting on September 1st), 13 projects have already opened Crowdloan, such as SherpaX (ChainX), KILT Spiritnet, Centrifuge (Altair), Manta (Calamari), etc. . In addition, there are more ways to play around the second round of parachain auctions, such as Zenlink and Bifrost have launched products that support Crowdloan;
For more details, please see this full monthly report.

2. Progress and cooperation
On August 3rd, Karura launched the fourth proposal adding KSM as the first kUSD collateral.
On August 4th, the Acala Foundation selected 3 preparatory ambassadors who have made positive contributions to the Acala community and officially became Acala senior ambassadors. For details, please refer to the "Announcement of the First List of Acala Chinese Community Senior Ambassadors".
On August 4th, Karura launched the fifth proposal to launch the KSM/kUSD trading pair in Karura Swap.
On August 5th, Karura launched the seventh proposal to start KSM mortgage lending kUSD, launch KSM/kUSD and liquidity incentive plan.
On August 6, the Karura community launched the Kusama network’s first decentralized cross-chain stablecoin kUSD through on-chain governance, and supported KSM mortgage lending kUSD, and launched KSM/kUSD and liquidity incentive plans. Currently, users can earn KAR liquidity incentives by adding KSM/KAR and KSM/kUSD liquidity and staking LP Tokens.
In August, the well-known on-chain risk simulation security Gauntlet recently made a new assessment of the kUSD collateral KSM of the Karura network, saying that it has been able to reduce the minimum collateral rate and liquidation rate of KSM, and the liquidation rate and minimum mortgage of the Karura network. Two parameter reductions have been done.
On August 12, Bryan Chen, co-founder of Acala & Karura, tweeted that he had completed the first XCM cross-chain "universal message" transmission. Different from the previous cross-chain transfer of assets, this is the first time that Kusama and Karura have completed cross-chain general message (remark) transfer, successfully verifying the feasibility of XCM cross-chain technology.
On August 16, Manta Network announced that it has successfully achieved cross-chain communication with Acala on the testnet through XCM. This cooperation demonstrates the cross-chain composability of Acala, and also verifies Manta's ability to make parachain assets private.
On August 20, the Acala development team has completed the optimization of the original EVM and launched the customized Acala EVM+. Now it can not only provide DeFi users with a similar Ethereum development environment, but also bring a functional experience that is 100% compatible with Ethereum (such as MetaMask, etc.). In addition, DApps based on Acala EVM+ can still have all the functions of Substrate, a modular development framework launched by Polkadot, including performance and customizability. At present, the Acala team has completed most of the development work of EVM+, which will be launched after the audit test is completed.
On August 20th, Polkawallet, the mobile wallet of Polkadot, has completed the access to the Statemine parachain, which means that anyone can create assets and NFT on their mobile phones anytime, anywhere, which can be used to create and manage assets, and there will be many in the future The assets are on the public parallel chain, and the Karura network will also support network intercommunication, helping more assets enter the Karura network to participate in enriching the gameplay of the DeFi protocol.
On August 24th, Karura is using SubQuery to extract and query data from Karura's chain, making Karura's application queries fast and efficient. Using Karura's newly released public SubQuery project makes developing dApps on Karura much faster now. This publicly available SubQuery project enables the Karura community to fork and build any dApp they want. Also, Karura dictionaries can make indexing faster.
On August 27, the 12th proposal was launched on the Karura network, which opened the first version of the LKSM function for internal testing.

Completed the support of SherpaX decentralized digital identity CID.
Completed SherpaX C-CARD NFT support.
Completed SherpaX EVM porting.
Development progress:
Implement the Musig2 multi-signature solution based on libp2p's rust version, including: the realization of the basic prototype of Musig2, the state transition of the communication round, and the support for bip340.
Compatible with the Schnorr signature of BTC after the Taproot upgrade, and compatible with the execution environment of ChainX, and can verify the Schnorr signature of BTC on ChainX.
Basically implement the rust version of MAST, support building MAST and generating Merkle Proof through input scripts
Implement the parsing and verification of the latest version of BTC's isolated witness program, including Taproot and Tapscript, where Taproot is the type of transaction that spends BTC through the key-path, and TapScript is the type that uses the script-path to spend BTC.
Completed the construction of the SherpaX EVM testnet (supporting MetaMask, Remix, etc. of the Ethereum ecosystem).
Taproot is an upcoming major upgrade of the BTC network. For this, ChainX is actively promoting a new cross-chain solution. The goal of the on-chain part is to realize the TapScript verification of the BTC-like network on the ChainX network. The goal of the off-chain part is to use ComingChat as the basis of communication, use MuSig as the multi-signature scheme, and introduce MAST to finally realize the threshold signature. Finally, this Taproot upgrade is completed through off-chain threshold signature + ChianX on-chain verification + BTC network service. At the same time, in order to accomplish this goal, ChainX is also applying for w3f/Grant-Program to seek corresponding support.
Development progress:
Apply for the w3f/Grant-Program for threshold signatures.

Phala's brand new test network Para-1 is officially launched. It operates based on the parachain mechanism and introduces a new version of the economic model and TEE Mining function for computing node testing. Users can experience and test the mortgage pool function on the test network by using test coins.
Launched the computing node data panel Console, which includes on-chain operations and data display of computing node machines and mortgage pools. Address: https://app-test.phala.network/console/
Release the governance mechanism on the Khala network chain, which is consistent with the governance mechanism of Polkadot and Kusama at the initial stage, that is, it is jointly governed by a tripartite organization-the public, the parliament, and the technical committee.
According to the Phala token asset allocation principle, 88.3 million ERC20-PHA have been transferred to the Khala bridge contract before August 9.

This is the first time TEA has appeared in Chinese media. It was also mentioned in Polkadot's OpenGrant and BuilderProgram before this. Because TEA uses a lot of different ideas and technical routes, in order to allow readers to relax their brains and accept new and different understandings, Kevin told several vivid stories in the interview to simulate how conventional blockchains and TEA treat security and operational efficiency differences.
