Alice und Bob

Alice und Bob take in-depth looks at the Kusama and Polkadot ecosystem. They make complicated facts understandable for the broader community.

After [announcing Subscrape to the world for the first time](https://twitter.com/alice_und_bob/status/1493714489014956037) a little over a month ago, the library has grown quite a bit and today I am proud to announce v1.0 of Subscrape and present the roadmap for Subscrape 2.0

## Releasing Subscrape v1.0
**Subscrape is a Python scraper for Substrate chains that uses Subscan.**

It is configured by a config file through which you use to tell the scraper which data to get. It is stored locally on disk and can then be queried and transformed to your needs.

[Subscrape v1.0](https://github.com/ChaosDAO-org/subscrape/releases/tag/v1.0) has just been released on the ChaosDAO Github. It allows for the scraping of extrinsics on any Subscan supported chain. The [Subscrape README](https://github.com/ChaosDAO-org/subscrape/blob/main/README.md) provides the basic documentation needed to understand the mechanics. If you have additional questions, feel free to reach out via DM on Twitter: [@alice_und_bob](https://twitter.com/alice_und_bob)

## The Roadmap to Subscrape 2.0
Subscrape is a personal project that evolves with my needs. As I see that it might serve the needs of others too, I am open sourcing it and give you a chance to influence what I do with it or for you to pick it up and continue development. Version 1.0 served the purpose of extracting crowdloan related data and further process it in a Spreadsheet.

Version 2.0 will focus on helping me do my taxes. Taxes in Substrate are a topic that is not yet deeply explored and could prove to become very difficult in the future. My country recently introduced a rather degen friendly legislation for crypto taxes, but it is still a huge challenge.

To do my taxes, I plan to introduce utilities to understand the capital flows of the following mechanics:
- Transfers in, out and between several owned accounts
- Staking rewards
- Crowdloan participation
- Airdrops/Paradrops
- Treasury tips
- XCM transfers between parachains
- DeFi
  - Swaps
  - Liquidity Provision
  - liquidity mining
- NFTs buys and sells
  -  RMRK buys and sells

This does not mean that this will be full-fledged application that supports all those cases. It means I will implement just as much as needed to fulfull my tax obligations. Corners might be cut sharply.

I welcome any collaboration on this repository. I will especially share any knowledge you are interested in to get up to speed quickly. But please do not expect that feature requests might be fulfilled if they do not fit my agenda.

I post updates on the project to Twitter from time to time. You will find the latest info by searching for the hashtag [#Subscrape](https://twitter.com/hashtag/Subscrape)

Feel free to retweet the [announcement tweet](https://twitter.com/alice_und_bob/status/1506040033899335680).

# What is it?

A DEX on the common goods parachain Statemint (& Statemine) on Polkadot, with these goals:

* Provide DOT liquidity against external tokens: BTC, ETH, KSM, USDT, USDC  
   * yes, USDC is coming to Statemint
* Enable Sufficient assets: Onboarding to Polkadot without owning DOT  
   * bring your own gas: pay fees in any sufficient asset
* Allow other DOT-bound pairs

# Details

* Mechanics  
   * Exchange commission of 0.3% goes to LPs  
   * Uniswap V1-like: only XYK curve planned, nothing fancy  
   * only pairs against DOT
* Tokens  
   * Parachains can register their native assets on Statemint  
   * permissionless pool creation

# FAQ

* Will it be on Kusama too

# Discussion

* Will provide much-needed liquidity relief
* Resistance is futile. It will be “the monopoly” in the mid-term and it will command the flow
* It will be a net positive for the ecosystem
* DEXes have a more challenging time now, fearing “the monopoly”  
   * They will have to provide superior value to traders and liquidity providers
* This creates a tectonic power shift, as a lot of attention now goes into how to work with it  
   * Lots of implications in fields like capital onboarding flows, XCM use cases, potential liquidity reuse
* Prediction: Statemint will become a trusted intermediary and settlement chain ([Tweet](https://twitter.com/alice%5Fund%5Fbob/status/1621111336104230912), [Forum](https://forum.polkadot.network/t/statemint-as-a-trusted-intermediary-and-settlement-chain-for-token-transfers/1951))

# Open Questions

* Would DOT incentives put DOT at risk of becoming a security?
* Can the Treasury become a liquidity provider and hold protocol-owned liquidity?
* Can LP be reused cross-chain?  
   * With XCM V3 Remote Locking?  
   * synchronicity is the key problem

**The first few hours and days understanding the Polkadot/Kusama/Substrate ecosystem can be rough. Where do you start your journey? Where do you get information? What can you trust?**

To find your way around, we created this little guide with the most important websites and communities for your journey into the ecosystem.

We will look into:
* Core information and sources
* News & Latest Developments
* Social Media

This article is also available as video:
https://youtu.be/lxRS-3qAEeM

## Core Information & Sources
The single most important source when you are just starting out is the official [Polkadot Wiki](https://wiki.polkadot.network/docs/getting-started). It explains basic concepts and is not shy to go deep an relevant concepts that they introduce into the blockchain world. The [Kusama Wiki](https://guide.kusama.network/docs/kusama-getting-started/) will go into details where things get more experimental or might be different from Polkadot.
### On-Chain
To get insights into what is happening on-chain, use the [Polkadot.js.org App](https://polkadot.js.org/apps/#/) (aka Portal) and see what is happening in governance via [Polkassembly](https://polkadot.polkassembly.io/).
### Explorers
There are three commonly known blockchain explorers, these are [subscan.io](https://www.subscan.io/), [polkascan.io](https://polkascan.io/) and [polkastats.io](https://kusama.polkastats.io/)
### Official Channels
The [Community page](https://wiki.polkadot.network/docs/community) offers all the channels. Communication of the core community happens mostly in Riot/Element.
### Price
The best aggregator for price information so far is [dotmarketcap.com](https://dotmarketcap.com/). They also offer info on Tokens and Tokenomics.
## News & Latest Developments
### YouTube
The YouTube Bubble isn't too big yet and next to [yours truly](https://www.youtube.com/channel/UC0alQ35JKnMo_ctzYITthbw), only a few channels exist:
* [KryptosChain](https://www.youtube.com/channel/UC0XiJui2llg9PHUz45jfycw): Daily News, mostly about the Dotsama ecosystem
* [PromoTeam](https://www.youtube.com/channel/UCrvyFYM29oQ-EAejZgYqmWA): Updates on the relevant developments
* [Crypto Elementary](https://www.youtube.com/channel/UCGGamrWe1ZK9IetVxi_VvhA): Parachain Auctions and Technicals so far
* [Jay Chrawnna](https://www.youtube.com/channel/UCqNw3CEyOD-bjjYYaxVyG3Q): A lot of FAQ explainers and commentary on Parachain Slot Auctions
* [DotsamaDeFi](https://www.youtube.com/channel/UCH73JWCVLkRVyCTq89rrEfA): Focus on DeFi
### Podcasts
* [Parachain Auctions Podcast](https://www.youtube.com/playlist?list=PL1fKlftNZ_xHakccBbVMJqOt5HehxQS40) by Kraken
* Layer 0 Podcast by [Teriyaki Don](https://twitter.com/TheTeriyakiDon)

### Social Media
* The ecosystem has a strong **Twitter** game with a lot of core people participating there. Our Twitter account has curated lists of important channels: [Lists](https://twitter.com/alice_und_bob/lists)
* **Medium** is another medium where a lot of information is exchanged. Again, a list of [channels we follow](https://aliceundbob.medium.com/following) can give you a jump start.
* **[Subsocial](https://app.subsocial.network/)** is an actual dedicated Social Network built on Substrate. Which means as long as you can't buy tokens and the faucet is only giving you a little, you will mostly be able to read there.
* **Reddit** game is weak so far but you can find a lot of questions being answered in the offical Subreddits.

## Ready to become part of the system?
**Then start by staking your KSM right on chain and earn higher interest than on exchanges:** Don't just let your KSM sit in your account doing nothing while you wait for the right moment. You can earn interest on your KSM and also support our channel.

The Latest on DotSwap - February 2023

*This article gives the first details on Polkalytics Account Reports, follows the path of an on-chain riddle, and begins the quest to survey the Polkadot Data Ecosystem*

**It always fascinated me how tens of thousands of people rush into Polkadot** parachains to test them out and experience the cutting edge of crypto, while at the same time, they have no clue how they are going to file their Polkadot taxes at the end of the year. Sure, taxes work differently for everyone. Depending on where on this beautiful planet they reside and what legal structure they have set up for themselves, they pay 50%, 20%, 10%, 2%, 0.2%, or 0% in crypto taxes. Some pay zero, but most have to pay something.

**It’s tax season in many parts of the world.** For some businesses that are deep into Polkadot, this means they have 50 or more accounts for all the parachains they use. And they need to report on all of those for their tax filings. The most common questions they need to get answered are: Which assets and how many did we have at the start of the year and at the end of the year? How much did we earn through staking?

**I was sure that someone would take that opportunity** and build a reporting tool that helps all those Polkadot community members get this problem solved. But after 1.5 years of waiting, it still didn’t happen. So I decided to take the engine I built to uncover the secrets of the chain ([including the 1337Riddle of Kusama](https://www.youtube.com/watch?v=gy-DNSpyROs)). I picked up the challenge to develop a tool that fully explains everything that happened on an account: Polkalytics Account Reports.

**After the official** [**announcement of the Polkalytics Closed Alpha Program**](https://polkaverse.com/10716/polkalytics-a-google-scale-analytics-service-for-polkadot-37079)**,** over 30 people applied to participate. 8 were able to get into the program so far and I worked personally with them to generate personalized reports and to file their taxes on time. After validating the product and getting feedback that it actually helps people, it’s time to share some details.

## How does Polkalytics Account Reports work?

Polkalytics holds a complete Google BigQuery (Big as in Big Data) database of all blocks, transactions, and events that ever happened on Polkadot and Kusama. When Polkalytics Account Reports gets tasked with generating a report for an address (or many addresses), it

1. analyzes all historical transactions and balance changes for that account.
2. It then classifies all account actions into potential tax categories according to what happened, e.g. transfers, staking rewards, etc. You then can use this report to apply the rules of your tax jurisdiction to it.

### Types of Transactions

The Polkadot and Kusama relay chains are already supported by Polkalatics Account Reports with the following classifications:

* Transfers
* Crowdloan participation
* XCM transfers
* Staking Rewards
* Fees
* Other minor stuff (index reservations, reserve repatriations, dust lost for deleting accounts)

## Apply for the Closed Alpha

After having successfully helped the first few users, Polkalytics is opening up for more participants. The fee to participate is 50 USD and will work on a first-come, first-served basis as capacity is available. Work in the coming months will focus on adding more chains and making reports available to as many people as possible at affordable prices.

If you want to skip the line, the current asking price is 125 USD.

There will be some promotional offers from time to time. Make sure to get them by subscribing to the [Polkalytics Newsletter](http://www.google.com/url?q=http%3A%2F%2Feepurl.com%2FihmNQ5&sa=D&sntz=1&usg=AOvVaw0nePZNUu6mJSYizfyZqqw3) and following [@Polkalytics on Twitter](https://www.google.com/url?q=https%3A%2F%2Ftwitter.com%2Fpolkalytics&sa=D&sntz=1&usg=AOvVaw2fHM8QbM5d%5FHTZj5U6OBGU).
