Email, as the key infrastructure for the mass adoption of the Internet, still plays an important role in our lives today. One of its biggest contributions is to save users from the cumbersome private key management process. Now, whether it is exchanging information or registering an account, email is the first door for users to enter the Internet.

At present, with the development of wallets and DID applications, the threshold for users to enter the Web3.0 world is also decreasing. Just like the traditional Internet, users entering Web 3.0 also need an efficient communication application to provide “native-level” services for information flow in the Web 3.0 world.

Obviously, as an application with very similar underlying logic and the widest audience coverage, email is the best choice for bridging the Web2.0 and Web3.0 worlds and serving Web3.0 native users. MetaMail based on Web3.0 is compatible with traditional mail protocols, supports Web3.0 users to use domain name services to create their own email addresses, and implements end-to-end content encryption through encryption technology. It is undoubtedly the best choice for Web3.0 communication. .

It is worth noting that at this hackathon, MetaMail also created user recommendation and other functions based on the Web3.0 relational algorithm protocol KNN3, further highlighting its differences and advantages with traditional email services.

BlockBeats had exclusive interviews with MetaMail and KNN3 before this hackathon. For details, see “Dialogue MetaMail: Web3.0’s Perfect Solution for Email” and “Dialogue KNN3: Web3 Needs Reliable Algorithms” for details.

For many people, Arweave is a simple data storage platform. In fact, Arweave can also support smart contracts, and its ecological application scenarios have been booming in the past period of time (BlockBeats Note, in “The Current Arweave Ecological Application, The Arweave ecosystem is described in detail in “It’s much more than just storage”). In this context, it has become a very good development opportunity to make good use of Arweave’s own data advantages to provide high-quality services for application construction in the ecosystem.

Kwil is a SQL database solution for building decentralized protocols and applications, aiming to build a highly usable and extensible architecture to improve the composability of decentralized data on the chain.By providing Web2.0 developers with a familiar and highly scalable decentralized SQL (Structured Query Language) database, Kwil can help developers complete dApp development in less time.

Under the decentralized architecture of Web3.0, developers need to deal with a large amount of scattered and complex data on the chain, which greatly prolongs the development cycle of the application, as well as the experience and scalability of the application itself. And KwilDB (Kwil Database) greatly simplifies the development process of applications and protocols by providing highly scalable decentralized data storage and query services, enabling dApps to seamlessly insert data from other applications.

By incorporating the decentralized data on the chain into the SQL database, Kwil can help Web2.0 developers to better adapt to the Web3.0 development environment. Developers do not need to make any changes to the current data to transfer applications from Web2. .0 ported to the Web 3.0 world. In addition, applications built on KwilDB can integrate and utilize data sets from other KwilDB users, and developers can also use data from other applications to build their own applications or protocols to achieve high composability and scalability.

working principle

We know that the data stored on Arweave is unstructured, only transaction IDs. In order to find the correct data in chronological order, the Kwil node looks up the relevant data on Arweave through the block indexer, and then the node uses this data to synchronize with the database running on the same dataset, the data in the Kwil database finds out the correct data data structure.

Interestingly, Kwil supports developers of applications or protocols to choose the payer of data storage fees, and developers can either bear all related costs or transfer costs to the community in the form of Gas. On the other hand, Kwil adopts the Proof of Secret mechanism, and community members can retrospectively verify the source of the data by paying the cost of data storage.

In-ecological application

Koii

Koii Network is a decentralized attention tracking protocol that provides incentives for Web2.0 and Web3.0 data content creators based on content traffic. Koii prepares a full-featured set of development tools for developers to build scalable dApps, and KwilDB is included as a community relational database.

Space And Time

Space And Time is an enterprise data warehouse solution designed to help dApps integrate cross-chain ecosystems using scalable OLAP queries. KwilDB is its integrated secondary data storage solution, and any data that cannot be included in the main Space And Time cluster is sent and stored on sharded KwilDB datasets.

Kyve

Kyve is a storage solution for the state of old blocks, designed to alleviate the storage requirements of nodes in the L1 public chain. Kyve’s uploaders and validators work together to ensure that block state data is validated, stored and retrieved on Arweave in the correct way. KwilDB is an incentivized Kyve native query layer that enables applications to insert and retrieve archived blockchain data without permission, and calculate remaining payments to reward the community.

church

Ecclesia is a free decentralized communication platform built on KwilDB, which combines the content organization capabilities of Slack and Discord with the content consumption capabilities of Twitter.

DeChat

DeChat is a decentralized censorship-resistant social network built on KwilDB. It uses a social media UI familiar to Web2.0 users, and aims to encourage freedom of speech and improve the existing social media model with the help of Web3.0 technology.

铜奖: DAOU, VOKA AI

DAOU

Inventory of four recent Web3 award-winning applications worthy of attention

In the future Web3.0 world, DAO will undoubtedly be the main place for people to work and socialize, and currently, from Seed Club to Dework, a series of infrastructure and application tools for DAO organizations are also being continuously improved, which are the preparation and tasks of DAO organizations. Distribution, salary distribution and other work to provide services.

DAOU is a tool-based application that provides credit ratings for DAO members. By using the two mechanisms of Soul Binding Token and Social Oracle (Social Oracle), the user’s activity data in the Web3.0 community is converted into verifiable on-chain data, including participating in activities on Discord, contributing code on Github, and on-chain. Roles in DAOs, etc.

Through the social oracle mechanism, DAOU encourages members in the same DAO organization to sign and verify the data produced by other members, and give each member a reliable score based on these data, which is the DAO member’s credit rating. The data verified by the social oracle will be released in the form of soul-bound Tokens through DAO, and can be used externally, such as on-chain credit loans, airdrop target screening, etc. (BlockBeats note, there is a detailed introduction to the soul-bound Token in “V God: “Soul-bound” Coins Will Be Your Blockchain Passport”)
