**Polkadot and Kusama News Authoring Tool**

- Many people get news about Kusama and Polkadot from online sources like Twitter and blogs, but it can be slow and hard to access.
- Sharing links on platforms like Telegram isn't very effective for reaching audiences quickly.
- Developers and marketers find it difficult to create eye-catching posts or images for social media.
- There’s a need for a tool that helps create quick and easy news updates and knowledge tips.

**Proposed Tool Features:**
- Users can create an appealing image just by writing a title and details.
- It will have templates to choose from for different kinds of posts, making sharing smoother.

**Use Cases:**
1. Developers can quickly broadcast good news by generating an image, so viewers can see the full content by simply clicking on it.
2. Users can explain concepts like "what is the Kusama council" in an easy-to-understand way by sharing custom images.

**Goal:** The tool aims to improve how news and knowledge are shared in the Polkadot ecosystem.

Rejected

Previous discussion can be found at [post 138](https://polkadot.polkassembly.io/post/138).


# Problems
We got news about Kusama and Polkadot from twitter, social media, and blogs. But to get them, first we need to open the corresponding links in the browser and sometimes we may need to login. For knowledge, usually we search some topic with google, or go to [substrate.dev](https://substrate.dev/) to search the tip we are interested in.

Problems with current situation:  
- News are not fast enough and not effective to readers. Even in telegram when we share the link, though we can see a short description, it's not cool and not effective to audiences.
- Twitter message authoring and post writing is time consuming, while it's nearly impossible for a developer or marketing staff to create some cool images to polish the content.
- It's hard for developers to share some knowledge in a flash and effective way.
- Image is the most popular way to broadcast info in China. We broadcast them in wechat chat groups and friends circle, but currently there are no convenient ways to generate flash news or knowledge tips for Polkadot ecosystem projects.

# Authoring tool

We propose a **knowledge tip** and **flash news** authoring tool to solve the above problems. With this tool we can:
- Write only title and detail to generate a cool image which is very easy to broadcast and friendly to content audience.
- Some image banners are prepared, and authors just need to choose one from them.

Following scenarios will be supported to help Kusama, Polkadot and other ecosystem projects to broadcast news and knowledge tip.

1. Project may have a flash good news which they want to spread it fast. Then a developer generate a image contains the news, and broadcast it to the telegram channels. Telegram readers just click the image, and the full content is shown to them, and they don't have to open the browser.

2. A normal user open this cool, create a image which explain 'what is kusama council', then broadcast it to social media. The content readers can reach this explanation in a fast way and ecosystem users can get this knowledge in a very clear way.

In Polkadot, Kusama and other parachains, RPC is the interface between DApp and the network. As the Polkadot network continues to expand, more and more parachains will be online, and more and more parachains will support smart contract functions. Faced with more and more parallel chains, developers need to build and maintain multiple blockchain nodes in order to interact with them, which will be a huge development cost for them. Whether it is facing the development and testing needs of developers or users' online DApp usage requirements, a convenient, fast and stable network access is one of the necessary conditions, and it is also the infrastructure of the Polkadot ecosystem.

Elara is inspired by [Infura](https://infura.io/) from the Ethereum ecosystem, named after Jupiter’s seventh moon. Elara's goal is to build a similar infrastructure and network public access services to provide developers with a unified access layer based on Substrate multi-chain. In addition, Elara will be used as part of the smart contract development service, and will be integrated with other components of the Patract toolchain in the future, in terms of contract development environment support, development tools component, contract deployment and DApp release. Elara will be Polkadot’s infrastructure, allowing developers to focus on building upper-level applications.

Patract Labs' treasury proposal for Elara v0.1

Europa is a new project designed to help developers create and test apps using Substrate, a framework in the Polkadot ecosystem. Here are some key points about Europa:

- Europa is a special environment for testing, making it easier to develop and debug applications.
- It has no complicated parts like peer-to-peer connections, focusing only on running the code.
- The project plans to create three versions, starting with basic features and adding more support later.
- Version 0.1 lets developers quickly start a private Substrate chain for testing without needing a whole blockchain.
- Future versions will improve error notifications and work with other tools to enhance the development experience.
- The team is working on milestones that include setting up a database, creating a block packing feature, and integrating with other systems.

FYI: This is copy from: https://polkadot.polkassembly.io/post/102, and Europa is the third project that we planned in our roadmap https://polkadot.polkassembly.io/post/100.

Github: [https://github.com/patractlabs/europa](https://github.com/patractlabs/europa)

Europa is inspired by [Ganache](https://www.trufflesuite.com/ganache), [Ethereumjs-VM](https://github.com/ethereumjs/ethereumjs-vm) and [Buidler EVM](https://buidler.dev/buidler-evm/) from the Ethereum ecosystem. Europa is a sandbox of Substrate runtime environment, which would be used to simplify the developing, debugging, and integration test when developers develop Substrate runtime applications and test pallet-contracts. The sandbox will remove P2P and consensus functions, just remaining the execution environment and RPC interface. We will wrap the core modules, then provide a local database, a detailed log print function, a concept of workspaces which isolates different developing environments, and interact with different front-end UIs. The sandbox has no time interval between producing blocks, so debugging can be optimised to be very quickly.


### Summary of Europa's future plan:

**1. v0.1: Have an independent runtime environment to facilitate more subsequent expansion directions.**

 The independent runtime environment of excluded nodes can be expanded more without the constraints of the node environment and WASM compilation, and can be easily integrated with other components. In this version, it is more like simulating the Ganache project in Ethereum ecosystem, enabling contract developers to develop without having to build a contract blockchain. Developers can quickly fire up a personal Substrate chain, which can be used to run tests, execute commands, and inspect state while controlling how the chain operates.

**2. v0.2: Modify at contract module level to provide more information **

In this version, we will fork the pallet-contracts module for secondary development. We will strengthen the part of the error notification for contract developers, such as providing:

* WASM stack traces, the function call stack during WASM contract execution;
* Contracts stack traces, the call stack of a contract calling another contract;
* Console.log, provides libraries and methods to print command lines during contract development;
* Strengthen the error type and error display of the contract module;
* Simple integration with Redspot;

** 3. v0.3: Improve the developement experience, strengthen collaboration with other tools, and extend the sandbox to be compatible with other runtime modules**

* Strengthen the integration with Redspot
* Strengthen the integration with polkadot.js.org/apps to achieve complete RPC support
* Support status data query


### Detailed design of v0.1 (6 weeks, 21 Sept ~ 2 Nov):

**Milestone 1 : (3 developers * 1 weeks)**

* Implement an independent runtime executive environment
* Implement `Externalities` trait for a `Externalities` -like object
* Implement needed `Extension` trait interface.

**Milestone 2 : (3 developers * 1 weeks)**

* Implement a local database for this runtime executive environment to store all trie data, block and extrinsic
* Implement a local database  to store a bypath k/v state data, for exporting and querying from those data.

**Milestone 3 :  (3 developers * 1 weeks)**

* Implement a block packing function to pack blocks directly rather than through consensus process, allowing to pack one or multiple extrinsics at once. 
* Providing a workspace concept to isolate different environment.

**Milestone 4 :  (3 developers * 1 weeks)**

* Implement RPC functions of "forward to height" and "backward to height"
* Providing a way to pack blocks directly to assigned height
* Revert current state to a reverted height

**Milestone 5 : (3 developers * 2 weeks)**

* Integration and testing


### Cost of v0.1 (18 developers * weeks)

* Operating activities: $3600 ( Rent and Devices: $200 per developer * week )
* Employee payments: $36000 ($1900 per developer * week)
* —————————— +
* Total Cost: $37800
* Exchange Rate: $4/ New DOT
* Treasury Proposal: 9450 New DOT


### How to verify v0.1: Youtube demo video & Github source

* Build and run in an independent executable file
* Can start from different workspaces, and a new workspace is an empty chain
* Can receive extrinsics to set_code, deploy and call contracts directly
* Can interact with Redspot
* Can use RPC to jump over some blocks and revert to a specified height to revert states

Patract Labs' treasury proposal for Europa v0.1

Description to be found here: https://polkadot.polkassembly.io/post/111

SubstraTEE Scalability Proposal

Redspot is a tool for developing blockchain contracts. Its main goals are to make developing contracts easier and to hide complex processes.

Future plans for Redspot include:
- Version 0.1 finished core functions using the Truffle framework.
- Version 0.2 will switch to the Buidler framework, adding new features and plugins.
- Version 0.3 will improve integration with other tools and languages.
- Version 0.4 will add helpful libraries.

Some problems with version 0.1:
- There isn’t an easy way to interact with contracts.
- Private keys can't be well protected, making it less secure.
- Developers can only run deployment scripts once with the same settings.

The next version will focus on improving user experience by adding:
- An interactive command line.
- Support for multiple deployments.
- Enhanced safety for private keys.
- Reports on the gas used during contract activities.

Copy from: https://polkadot.polkassembly.io/post/101

Github: [https://github.com/patractlabs/redspot-0.2](https://github.com/patractlabs/redspot-0.2)

Redspot's goal is to standardise the contract development process, hide the underlying compilation details of the contract, and combine the sandbox, library, API, SDK and other plugins to create a one-stop smooth contract development process. We have finished the first [proposal](https://polkadot.polkassembly.io/motion/7) requirements for v0.1,  and written a development [report](https://polkadot.polkassembly.io/post/78).

### Summary of Redspot's future plan:

1. v0.1: Build core available functions based on Truffle framework.
2. v0.2: Migrate to the [Buidler](https://buidler.dev/) framework to enhance plugin extensibility and add some functions to provide a smoother development workflow.
3. v0.3: Imitating Buidler's plugins, combined with the characteristics of Substrate to add various plugins, such as waffle, and began to integrate multi-language SDK.
4. v0.4: Following the case of Buidler, add appropriate libraries, such as typechain, etc.

### Problems of Redspot v0.1:

Although we have completed all the basic functions of Redspot, there are still some inconveniences in use. E.g:

* There is no convenient interactive cli for simple interaction with deployed contracts;
* Only the private key in plain text is supported in the configuration file, derivation through seed is not supported, and the password cannot be hidden;
* Under the default instantiation address logic of pallet-contracts, the contract address generated by a single account with the same parameters and the same WASM code is unique. This is not like Ethereum's single account can repeatedly deploy the same contract with different addresses. Therefore, after the deployment script and test script are written in Redspot, they can only be executed once. Otherwise, during the second execution, the execution will be interrupted during the deployment phase because it cannot be deployed. This requires script developers to pay careful attention to the writing method, otherwise it is easy to make mistakes. Redspot hopes to simplify this process.
* When deploying scripts and test scripts are instantiating or calling contracts, gas_limit needs to be written in after estimated whether the current assets are sufficient to support contract execution. Redspot currently simply fills in a default value, and does not have an estimation method, and does not know the gas consumption after execution;

### Detailed design of v0.2 (6 weeks, 21 Sept ~ 2 Nov):

The Buidler framework provides a "plugin" model, which can give Redspot great scalability and flexibility. This framework can also support Redspot to connect with contract modules on different parachains. For example, you can replace the environment of the target chain through plugins, add SDKs in other languages, and add extensible functions. In v0.2, Redspot will migrate all the functions of v0.1 to the new Buidler framework, and write various plugins to solve the problems of v0.1.

**Milestone 1: (3 developers * 1 weeks )**

Fork Buidler framework and modify it to suit the Substrate blockchain, then migrate all the current features in  Redspot v0.1 as inner plugins to this new framework.

**Milestone 2: (3 developers * 1 weeks)**

Support an interactive cli to operate deployed contracts, this cli will include injected polkadot.js interface and other helper functions, global env, key pairs, and connected node.

**Milestone 3: (3 developers * 1 weeks)**

Plugin 1: key pair support.
* Developers can use a private key directly;
* Developers can use a seed, and can derive account from this seed;
* Developers can use indicate a path for the keystore file, so that the private key will not appear in the config file.

**Milestone 4: (3 developers * 1 weeks)**

Plugin 2: multiple executing test support. This plugin provides a way to allow developer to deploy contracts more than once using same account and parameters in tests.
* Developers can use “beforeTest” to derive accounts and transfer some balance to this new account.
* Developers can use this new account to deploy contracts.
* Every executing test command will derive new accounts automatically.

**Milestone 5: (3 developers * 0.5 week)**

Plugin 3: [Jupiter](https://github.com/patractlabs/jupiter) test-net support as deploying environment;
* Jupiter test-net will use a flag storage to allow developers to use same account, same parameters and same code to deploy more than once.
* This plugin will develop a matching interface to interactive with Jupiter to set flag.
* This plugin’s env will allow developers to do deploying and testing in a normal way.

**Milestone 6: (3 developers * 1.5 weeks)**

Plugin 4: gas usage report.
* This plugin can print gas usage per test phase and deploying actions.
* This plugin can print gas usage per interactive cli.

### Cost of v0.2 (18 developers * weeks)
* Operating activities: $3600 ( Rent and Devices: $200 per developer * week )
* Employee payments: $27000 ($1500 per developer * week)
* —————————— +
* Total Cost: $30600
* Exchange Rate: $4/ New DOT
* Treasury Proposal: 7650 New DOT

### How to verify v0.2: Youtube demo video & Github source

* Replay all v0.1 tests in v0.2
* Show how Redspot v0.2 interactive cli works

**Workflows:**

* Use "deploy" command and execute deploying scripts
* Use interactive cli
* Call deployed contract
* Send extrinsics to call a contract
* Deploy a new contract in cli

**Plugins:**

* key pair plugin:
    * allowing developers to use seed, private key or a keystore path in config
* multiple executing test plugin:
    * could repeat any test command without any changes in test scripts.
* Jupiter test-net plugin:
    * could connect with Jupiter test-net by using a config flag in config files
    * could repeat any test command without any changes in test scripts.
* Gas usage report plugin:
    * could print gas usage for every test phase
    * could print gas usage after calling a contract in interactive cli

8btc is also a host of [Hangzhou Blockchain Week](https://www.8btc.com/gbsf-2020?lang=en) and [World Blockchain Conference](https://www.8btc.com/wbc-2019/?lang=en), which will be held every year. Besides these two conferences, 8btc will host plenty of meetups with different themes every year. [Chainge](https://www.8btc.com/author/61023) is the name we gave to tech-related meetups, which is also for the Polkadot meetup we are about to host. Chainge has seen most famous blockchain teams in China joined in, including IRISnet, Nervos and PlatOn.

As a validating node of Polkadot, 8btc appreciates what Polkadot brings to the blockchain world and Web3 development. Though Polkadot is already a well-known project in China, most people know little about the related tech and what Polkadot can bring to the blockchain revolution.

So the meetup named ‘[Polkadot and the Trust World it Brings](https://www.chainnode.com/event/469852)’ will get more people to truly learn about what Polkadot is and will be, instead of pure speculation. Hangzhou is only our first station, there will be more in different cities of China.

The meetup was from 1:30pm to 5:00pm, on Sep. 12th (GMT+8). Entrance was free and there were more than 130 people to attend the meetup.

Pls feel free to ask me anything. Thanks!

### Summary of Web3Go Proposal for Moonbeam and Moonriver Data Analytics

- **Objective**: Continue data analytics for Moonbeam and Moonriver using Web3Go's stream data processing system.
- **Motivation**: Moonbeam and Moonriver lack a data analytics platform, making it hard for users to access and view data. Web3Go fills this gap.

- **Team Experience**: Web3Go has been working in the Polkadot ecosystem for over 2 years, recently expanding from 8 to 15 team members.
- **Rationale**: Web3Go is the preferred choice for data review and usage in the Moonbeam ecosystem but needs more resources for customized services.
- **Cost**: Proposal seeks $30,000 equivalent in GLMR or MOVR for server and manpower costs over three months (April to June 2023).
- **Deliverables**: Plans to deliver dashboards for Moonriver, inflation, and dApp activity for both networks.
- **Implementation**: Involves setting up archive nodes, indexing data, database maintenance, data processing, and visualization.
