The comments correspond to the participation of some attendees. Welcome to the wonderful Polkadot ecosystem =) <a href="https://x.com/Polkadot_per">Polkadot Peru</a> <img src="https://i.ibb.co/PvLz2hB7/Whats-App-Image-2025-02-20-at-12-23-30.jpg" alt width="640" height="360" />

Education workshop by Polkadot Peru

Lima was the venue for the Polkadot Kusama LATAM Day 2021 (I appear as the main coordinator), where a strong community of developers from the Dotsama ecosystem was born, which has also been joined by the interest of organizations such as companies, universities or others. technological communities. Due to this, the need arose to carry out **a Side Event to bring the main activities of DECODED closer** and in a **hybrid format** (virtual and face-to-face) to the entire local community.

**The funds of this Side Event** (despite appearing in the [main program](https://chain-fir-08d.notion.site/7cd5b0c1535c46ceb8928a5a7f9f5183?v=a2381a36cd6e4bf6bccc7c49a6fbe4c4)) **were not covered by the treasury**. However, the will of the community allowed that if **it could be executed under particular efforts**.

Below **I share the detail of the costs** associated with the execution of the event, as well as **a report** showing the detail of the **digital impact** that was generated. **Feel free to review** and rate the work done.

![FINAL THANKS](https://themvp07.github.io/DECODED-LIMA/img/thanks.png)

This was possible under great coordination where the small contribution of various people to make all this possible takes on value, **beyond the economic is the value of solidarity between technology communities**.

**NOTE**: **The allocation of funds** for this activity will not affect the commitment to continue carrying out activities that continue to add positive effects to the network and its community, however it **represents recognition and compensation** for a great effort made for the benefit of the Dotsama ecosystem and its participants.

**Update**: I´ve completed my on-chain identity. Feel free to tell me about any other review.


Host DECODED Side Event - Lima (Costs & report)

Hello people, i want to introduce my project &ldquo;JAM Whitelist Role Authorizer&rdquo;, an implementation that uses the JAM SDK to provide a role-based and whitelist authorization system. This project is a significant contribution to the Polkadot open source ecosystem and demonstrates the potential of the JAM SDK to develop practical and scalable solutions.
What does this project do? The JAM Whitelist Role Authorizer allows managing authorized addresses, assigning roles (administrator, participant, observer), and running an interactive game where participants answer questions under supervision. The system ensures that only authorized addresses can perform specific actions, ensuring transparency and security in decentralized environments.
Additionally, the repository&rsquo;s resources are available in both English🇬🇧 and Spanish 🇪🇸, making it easy to use and understand for a global developers.
Open Source Code: <a href="https://github.com/Themvp07/JAM-Playground-SDK">Github</a>
JAM SDK Components Used
1.jam-types (Implemented) Description: This crate contains basic types and structures needed for working with services and authorizers in JAM.
Components Used:
<ul>
<li>Authorizer: Represents the JAM system's authorizer. It contains two main fields: code_hash: A hash representing the program code. param: A parameter that can store additional information (e.g., the admin's address).</li>
<li>CodeHash: Represents a 32-byte hash used to validate whether a hash belongs to a list of valid hashes.</li>
<li>AuthParam: A parameter used to store additional data related to authorization.</li>
</ul>
Usage in the Project:
Authorizer is used to manage the validation of authorized addresses.
A CodeHash is dynamically generated based on the admin's name and used to verify the authenticity of operations.
AuthParam is extended with the admin's address to track who performed certain actions.
&nbsp;
2.jam-pvm-common (Reviewed for Future Implementation) Description: Provides common functionalities for working with the PVM (Parity Virtual Machine).
Current Usage: Not explicitly used in the current code.
Future Suggestion: It could be used to ensure that data generated by the authorizer is compatible with the PVM runtime environment. For example, you could implement specific serialization/deserialization functions to handle data in the format required by the PVM.
&nbsp;
3.jam-bootstrap-service (Reviewed, Used as Reference)
Description: A basic service useful for creating initial configurations (genesis) in JAM.
Usage in the Project: Cloned as a reference to understand how to configure a basic service in JAM.
Future Suggestion: It could be used to define an initial configuration that includes predefined addresses for the admin, participant, and observer.
&nbsp;
4.jam-null-authorizer (Used as a Starting Point, but Not Present in the Current Code) Description: A basic authorizer that allows testing without authorization restrictions.
Current Usage: Not explicitly used in the current code.
Future Suggestion: It could be used as a starting point to implement more advanced test cases. For example, it could be integrated to test scenarios where no authorization is required.
&nbsp;
5.jam-pvm-build (Reviewed but Not Publicly Available) Description: A CLI tool that allows building PVM code blobs for services or authorizers.
Current Usage: Not explicitly used in the current code.
Future Suggestion: It could be used to compile the custom authorizer into a deployable PVM blob.
&nbsp;
Community Value
This project not only demonstrates how to effectively integrate and use the JAM SDK, but also serves as a practical example for other developers wishing to build similar services. It also:
<ul>
<li>Encourages adoption of the JAM SDK by providing a real,easily adaptable use case for other functional services.</li>
<li>Provides a modular and extensible solution that can adapt to various authorization scenarios in decentralized applications.</li>
<li>Guidance documentation available in multiple languages.</li>
</ul>

Example of ideas for future implementations
Potential Application in Polkadot Blockchain Academy: This role and authorization system could also be adapted to create a useful scenario in the Polkadot Blockchain Academy. For example, the entrance exam could leverage this resource to be more transparent and fair:
<ul>
<li>Administrator: Defines the questions and manages the process.</li>
<li>Participant: Answers the questions within a limit of operations.</li>
<li>Observer: Monitors the results and ensures impartiality.</li>
</ul>
By using a blockchain-based system, it is ensured that the process is immutable, transparent, and verifiable by all involved. This could improve trust in the selection process and make it more inclusive for global candidates.
Connection with video games like DOOM executed in JAM: The system developed is an essential component for managing who can interact with services in JAM. For example:
<ul>
<li>Access Restriction: In the case of DOOM or another video game, it is possible to use this authorizer to restrict who can deploy or run the application.</li>
<li>Role Assignment: We could assign specific roles, such as administrators who can modify game parameters or users who can only play the game.</li>
</ul>
In the case of DOOM, these components could be used to:
<ul>
<li>Validate that the DOOM binary has not been modified.</li>
<li>Authorize certain users to run the game.</li>
<li>Store relevant metadata, such as the player address or game state.</li>
</ul>
Thank you for your attention, I hope this resource, documentation and implementation ideas will be useful for everyone. See you in the decentralized future that is getting closer and feel free to share questions and comments =)
Note: Thanks Gav and Parity team by this interesting piece of software

Example of&nbsp;ideas for future implementations 
Potential Application in Polkadot Blockchain Academy: This role and authorization system could also be adapted to create a useful scenario in the Polkadot Blockchain Academy. For example, the entrance exam could leverage this resource to be more transparent and fair:
<ul>
<li>Administrator: Defines the questions and manages the process.</li>
<li>Participant: Answers the questions within a limit of operations.</li>
<li>Observer: Monitors the results and ensures impartiality.</li>
</ul>
By using a blockchain-based system, it is ensured that the process is immutable, transparent, and verifiable by all involved. This could improve trust in the selection process and make it more inclusive for global candidates.
Connection with video games like DOOM executed in JAM:&nbsp;The system developed is an essential component for managing who can interact with services in JAM. For example:
<ul>
<li>Access Restriction: In the case of DOOM or another video game, it is possible to use this authorizer to restrict who can deploy or run the application.</li>
<li>Role Assignment: We could assign specific roles, such as administrators who can modify game parameters or users who can only play the game.</li>
</ul>
In the case of DOOM, these components could be used to:
<ul>
<li>Validate that the DOOM binary has not been modified.</li>
<li>Authorize certain users to run the game.</li>
<li>Store relevant metadata, such as the player address or game state.</li>
</ul>
Thank you for your attention, I hope this resource, documentation and implementation ideas will be useful for everyone. See you in the decentralized future that is getting closer =) NOte: Thanks Gav and Parity team by this interesting piece of software

VOTE NAY - Wrong category- [Retroactive Funding] JAM SDK Implementation of reusable service

Polkadot Experience Beta &mdash; Arequipa This tip corresponds to a 2-day workshop run with own funds and that did not receive funds from any treasury or bounty last year.
Polkadot Experience that I carry out to provide workshops to developers in various locations and that last year had its second edition, in this case this request corresponds to the Arequipa Peru edition.

Quick context: Arequipa is the city in Peru with the greatest relevance at the level of software development in the country, for this reason it is preferred by technological giants to carry out recruitment and the Arequipe&ntilde;a community is known in Silicon Valley for annually organizing the Techsuyo conference. These were the reasons for holding 2 days of workshops there.
For 2 days (3 hours per day) a workshop was provided for developers where they were able to explore various resources available in the Polkadot ecosystem by completing theoretical and practical exercises.
Activity agenda:
Day 1
The workshop started with a basic introduction to cryptography. This covered:
&bull; Hash functions
&bull; Elliptic curves
We then moved on to a basic introduction to blockchains, covering:
&bull; Blockchain evolution (Bitcoin, Ethereum, Polkadot)
&bull; Decentralized application architecture
&bull; Smart contracts explained
&bull; Key concepts in Rust.
Workshop: Participants will be able to create interactive logic using Rust.
Day 2
On the second day, we focused on the Polkadot ecosystem and built fully functional blockchains using the Polkadot SDK:
&bull; Introduction to Polkadot and its architecture.
&bull; Solutions available in the Polkadot ecosystem
&bull; Importance of XCM interoperability between chains.
Workshop: We learned and successfully completed a implementation about Substrate, the blockchain development framework provided by the Polkadot SDK.
This was the first time that this type of blockchain activities was carried out in Arequipa and obtaining great results among which the following can be mentioned:
<ul>
<li>Massive participation during the activities.</li>
<li>Inclusion of participants in official channels of the Polkadot ecosystem.</li>
</ul>

Compensation tip for Business Development activity and grow C-Level ecosystem

Hello everyone, <a href="https://x.com/simonxpe">Saimon</a> Polkadot agent here =)
This time I am asking for a tip to offset the travel and lodging expenses generated by my in-person attendance at the Web3 Summit and at the headquarters of the Web 3 Foundation.
During these activities I was covering as many details as possible to be able to share valuable information with the Spanish-speaking community due to the low presence in this type of activities.
The content was focused during the Web3 Summit on showing the main activities as well as those valuable experiences that are not perceived through the recorded broadcasts.

During the visit to the offices of the Web 3 Foundation I conducted an interview with Bill, director of education, who shared experiences, challenges and recommendations.
