## Ongoing costs for the running of high performance, scalable, and reliable data indexing infrastructure for most of the DotSama ecosystem (and growing).

Archives are an important piece of DotSama data infrastructure provided by Subsquid. They provide access to on-chain data in GraphQL format for all major parachains on Kusama and Polkadot, with more chains added as the ecosystem grows. They are being used as a data source for Squids and for efficient data exploration and ad-hoc queries. An up-to-date list of Archives is kept in a public Archive Registry
All archives can be accessed and queried via an web intuitive GraphiQL interface and are often used as developer friendly replacement of a block explorer.

Over the last 3 months (March, April, May 2022) we've provided a free public data indexing service for ~35 Substrate blockchains (some archives have been dismissed, new ones have been added), so that everyone interested in the projects can publicly access indexed data on Substrate Events, Extrinsics, Storage Items and EVM logs.

Between 2022-03-20 (when tracking has started) and 2022-05-06 Subsquid’s Archive infrastructure has collectively:

- Served a total of 1,213,705,478 (1.2 billion) queries
- The highest daily total was 394,214,930 responses in a single 24 hour period
- Our 7 day average at the end of this period is over 25 million responses each day.
- Kusama and Polkadot chains represent a very important share of the demanded data, with 10 and 2.8 million queries per week, respectively

This proposal includes the combined costs for running Archives for Polkadot and its Parachains, which amounts to a total of  USD $16,044.40 - [raw data is here](https://docs.google.com/spreadsheets/d/1RkNQ6-10u_nmmNy2Nkwi-i9EDXv6VwwLJw4DdJVx1pQ/).

Thomson Reuters Foundation (TRF) proposes a strategic partnership with Every.org to educate non-crypto individuals and journalists about Web3 and blockchain technologies. This partnership aims to counteract simplified and inaccurate media narratives by developing a pilot training program. TRF plans to conduct extensive media mapping and discourse analysis, followed by a tailored training course for journalists in Europe. The course will cover blockchain basics, debunk misconceptions, and connect journalists with experts. Marketing efforts will leverage LinkedIn and Twitter to reach the target audience. The pilot program includes online courses, mentoring, and in-person workshops, emphasizing hands-on learning and peer collaboration.
