In the first speech, Qinwen introduced "The Development of Polkadot Smart Contracts" in detail. Qinwen said that Polkadot is built on the basis of Ethereum, focusing on solving the problems faced by Ethereum. Each development team can access the Polkadot ecosystem through access to parachains, parallel threads, or through smart contracts. "If the Polkadot ecosystem wants to achieve exponential innovation and deploy more complex financial DeFi applications, we still need to actively popularize the Wasm contract ecosystem (corresponding to EVM)."
In addition, Qinwen also compared Kusama with Polkadot, pointing out that the application scenarios and positioning of the two are different. "This card slot auction will be conducted on the Canary network (Kusama) first, and then on Polkadot. This is also based on our positioning of these two networks at that time. The Canary network can be compared to the wavelet card , all advanced experimental functions will be deployed on this network, and then transplanted into the Polkadot network after stabilization.”
The following is Qinwen's speech sharing, organized by Odaily:
Hello everyone, welcome to the Bifrost Parachain Auction Launch Conference. I am QinWen from the Web3 Foundation. As you know, Gavin Wood (the founder of Polkadot) published the rules of the Kusama card slot auction on Medium two days ago. I would like to thank the online audience for their support of the Polkadot-Kusama parachain auction. The following is my contact information, and you are welcome to communicate with me through email and Twitter.
Today's sharing, first of all, I want to introduce the origin between Polkadot and Bifrost.
The first time I met Lurpis (Bifrost co-founder) was at the Hangzhou Hackathon in July 2019, when he made a demo to apply for funding from the Web3 Foundation. This Demo is to build a cross-chain bridge between EOS and Polkadot, which is also the prototype of Bifrost. It was also that hackathon that laid a solid foundation for Polkadot's strong ecological team in China today.
Since then, Bifrost has also actively participated in the development of the Polkadot ecosystem, from the Substrate Developer Conference in Berlin to the web3 training camp in Shanghai... The Bifrost team is also the registrant of the identity on the chain of the Canary Network (Kusama), making contributions to the entire ecosystem. huge contribution. Polkadot and the foundation team have always been proud of the Chinese ecology.
Next, I would like to introduce the basic framework and mechanism of Polkadot, including the important time points of the parachain. We hope that ecological partners can actively participate and support high-quality teams in the ecosystem.
As everyone knows, Dr. Gavin wood, the founder of Polkadot, was once the CTO of Ethereum. Polkadot is also built on Ethereum, hoping to solve the scaling and performance problems that Ethereum is facing today. Therefore, we have adopted a heterogeneous sharding structure, so there will be parachains and parallel threads. Development teams can share the security of Polkadot by accessing parachains and parathreads.
In addition, Gavin wood also created the Substrate framework. Through the Substrate framework, the development team can quickly write their business logic in a modular way without writing the chain themselves. In addition to the above two ways to participate in Polkadot, developers can also deploy on our network through smart contracts or runtime pallets.
In the picture above, you can clearly see the multi-chain ecology in the Polkadot world. The left part is our ideal network effect when the parallel chain network world starts to operate; on the right part, you can see some important network components, including the relay chain, validators, parachains, checkers, and external chains. network structure.
Back to the smart contracts we just mentioned. Many developers, including Bifrost and Patract founder Yue Lipeng, have been working to promote Wasm smart contracts in the Polkadot ecosystem. EVM contracts are known to have driven Ethereum’s success. Gavin wood also emphasized at this year's Consensus conference that the Wasm contract is an important part of the Polkadot ecosystem. If Polkadot wants to achieve exponential innovation and more complex financial DeFi applications can be created, we still need to actively popularize the Wasm ecosystem. Currently Wasm technology is being applied in many major companies, and developers including Bifrost are actively promoting the development of Wasm in the Polkadot ecosystem.
In addition to the several structures just mentioned, cross-chain communication is also a very important part, such as XCMP and SPREE. Gavin also mentioned some recent developments in his recent blog, such as making parallel chain calls asynchronous information transfer.
The picture above is a vivid, vivid and intuitive comparison of the two networks of Polkadot and Kusama. For loyal fans of Polkadot, everyone is familiar with this concept; but if it is the first time to understand our network through card slot auction, this picture is still very worth looking at.
Our card slot auction this time was first conducted on the Canary network (Kusama), and then on the Polkadot network, which was also based on our positioning of these two networks at the time. Canary network can be compared to wavelet card. All advanced experimental functions will be deployed on this network, and then transplanted into Polkadot network after stabilization.
Last month, we announced the plan for the parachain at the community meeting. We will have 10-30 public welfare parachains. The currently launched Statemine asset chain is a public welfare parachain maintained by the Parity team. At present, there is already an NFT module on the Statemine parachain, which can issue some assets similar to stable currencies, and then there will be 40 to 90 parachains to provide very important infrastructure in the community. What Bifrost is currently doing is a very important part of the parachain pledge model, which can release a certain amount of liquidity for token supporters. In addition, there are 50 parallel threads to support ecological teams with different needs.
The above picture is our auction schedule, and we are currently entering the red box part. The upcoming card slot auction is very critical in the whole plan. The previous process was that we launched Shell first, and after Shell was upgraded to Statemine, Gavin also released this schedule in his blog.
The above page is more important for community members who want to actively participate in ecological support. You can support the project through the trusted centralized institutions shown in the figure, including Binance, Huobi, Okex, Kraken, and Kucoin exchanges. Or you can participate in the project through decentralized DEX and wallet.
The bidding for the first parachain will start on June 15th. I hope everyone can support the entire card slot auction. Thank you, and that concludes my speech.
