And it's a wrap for the ETHIndia Fellowship🫡 I have to say that I am a bit overwhelmed that it's been 8 weeks already. In today’s post, I’ll be talking mostly about the project that I built during EIF and how things turned out, the current state of the project, and what I have in mind for the future.

I’ll put up all the relevant links for you to check out right at the start in order to give you more context on the project.

Just to give you a quick brief about the project, I started building Pixie🦄 because I wanted to build something that facilitates a seamless experience of sharing files, allows users to have complete control over who has access to their files, and further provides the ability to monetise💰 their files. If you checkout the project, I might have been able to pull off some parts of it, but I think there’s still so much that can be done, and I feel I am in a good state to execute things from here, as I have way more context on how to proceed with it than I had at the beginning of the project.

In the current state of the project:

• You can store your files securely at a place (I call it the Pit)🕳️

• Share access to a file with specific wallet addresses.

• Add a paywall around your files by gating them with ERC1155 tokens🎟️

There are several components to the project, and I'd like to talk about them briefly:

The smart contract for the project was simple and clean enough to serve its purpose. The only thing I had on chain were file IDs for a user and the ability to mint specific ERC-20 tokens for a file. Other than that, all of the file and user data was stored in Polybase

The main logic for encrypting and decrypting and adding access control conditions to a file was handled via the Lighthouse SDK. I really like what they are doing, and I had a few interactions with people from their dev teams—really helpful and cool folks.

I want to keep building Pixie and get it into production as soon as possible, but before that, I’ll spend some time figuring out the product fit. I’ll try talking to people who would benefit from a solution like this and get their thoughts to improve my overall perception and possibilities for the project.

The entire build phase was nothing but a joyride for me. I had the time of my life building Pixie, making progress one step at a time.

Here's a new entry where I talk about my sixth work week at EIF 3.0⚙️

The sixth week was enjoyable because I spent the most of the time working on my project🦄, which attempts to give a method for sharing encrypted data through IPFS as well as possibilities for charging for file access.

I started by creating the logic to encrypt files, and then I used Web3.storage to store the encrypted data to IPFS. I was encrypting data using the cryptoJS library's AES option. In a nutshell, I began with image and pdf files, transformed them into arrays, then word strings, and finally used an encryption key to run the AES over this string. This blog served as a source for me🔗

I then learned about Lighthouse, which already performs some of the file storage and sharing over IPFS that I was attempting. After giving it some thought, I choose to abandon my original method in favour of building on top of the Lighthouse. This choice turned out to be prudent because it allowed me to leverage Lighthouse's file sharing and access management features while concentrating more on the project's monetization. On this front, I have made a lot of work, and I am enthusiastic about the possibilities of Pixie.

I plan on finishing up most of the project functionality by this week. And devote the next week for revamping the UI and last tweaks and finishes.

So I am back to sharing my EIF3.0 experience with you all. This week was filled with exciting events and work. I started working on my project and will be talking more about it later😀

We started the week with a discussion about DeFi💰 protocols. Each fellow was assigned a DeFi protocol and had to present it to the group. I was given the Timeswap protocol. Pretty cool project I must say. 

Timeswap is a fully decentralized AMM-based money market protocol on Ethereum. It is a non-custodial, immutable, censorship-resistant peer-to-pool protocol that works without oracles or liquidators.

One thing that stood out to me was how they reduced their dependency on the Oracles to determine things like interest rates and collateral multipliers on loans. You can find my presentation here🔗

There was also a very cool discussion on Defi with Samyak Jain (InstaDapp), Francesco Renzi (Superfluid) and Arjun Bhuptani (Connext).

After four weeks of finishing up the speedrun challenges, I have now finally started working on my project.

The project is called Pixie🦄. I have a thing for this name, and I tend to name most of my projects around it: pixiepop, pixieplay, and pixieclub, to name a few. Hahaha, I know it's a funny thing, but it is what it is.

Very briefly, the idea is to build a file sharing and storage platform on top of IPFS and allow users to manage access to their files with other wallet addresses, i.e., whether they want their data to be public or restrict access to some people. Later, also giving them the privilige to monetise their files, let's say token-gating them with NFTs or having their own creator tokens in order to access their files.

You can find the detailed project description here🔗

I have already started building it, and you can find the repo here🔗

Overall, Week 5 was a busy but exciting week at the ETHIndia Fellowship. I learned a lot about DeFi protocols. I am really hyped and thrilled to start building the project and can't wait to see it come to life.

Here I am summarising my thoughts on yet another exciting week at EIF 3.0.

As the Speedrun Ethereum tasks came to a conclusion this week with the completion of the 👛 Multisig Wallet Challenge and the 🎁 SVG NFT 🎫 Building Cohort Challenge, I began work on a capstone project for the fellowship🙌🏻 I'm quite enthusiastic about my idea and have been wanting to build something like this for a while. The idea has received positive feedback from the mentors and other people with whom I have discussed it. More to come about the project in the coming blogs xD

Moving on to things I worked on this week….

👛 Multisig Wallet Challenge

What is a Multisig, then? What it sounds like is precisely what it is.

A Multisig wallet is a wallet that adds an extra layer of protection by requiring many users to approve each transaction. Imagine it as a safe deposit box that can only be opened with two or more keys🔐. You might be in possession of one key, and a dependable friend or family member might be in possession of the others. To access the items inside the box and open it, all keys are required. Similar to this, a Multisig wallet may have a number of users, each of whom has a unique "key" or digital signature that must be present in order to approve a transaction. This might be you, your spouse or partner, a business partner, or other reliable people🧑🏻

🎁 SVG NFT 🎫 Building Cohort Challenge

The project was simple and interesting. I explored the possibility of storing NFT metadata and images on chain as encoded strings on chain. This was new to me all this time. I had only seen NFTs with their images pinned on IPFS and URIs attached to the NFTs. But here, we store TokenURIs and other data (name, description, attributes, etc.) for an NFT against their TokenIDs on chain and serve them dynamically from the smart contract on the frontend. Pretty cool!

Overall, the fourth week was fun and introduced me to new, cool things. I implemented things on my own, a little less mostly because I was playing around with the existing stuff, but nonetheless, it is always fun tinkering!

Back at penning down my experience at EIF3.0, got some exciting updates xD

My second and third weeks have decided to team up. I should warn you, this might be a bit of a marathon, but fear not - I'll do my best to keep it brisk and buoyant. Let’s roll!🫡

I must say, the second and third weeks were quite exciting. During this time, I had the opportunity to work on four different projects that allowed me to explore various new concepts and technologies related to decentralized applications and the Ethereum ecosystem. Overall, it was a lil challenging yet fulfilling experience that helped me grow as a developer. Here goes the gist of all the projects shipped in the last two weeks

🏵 Token Vendor: The first project I worked on was a token vendor, which allowed me to mint my own ERC-20 tokens and then buy and sell them through the vending machine itself. This project was particularly exciting because it gave me a taste of what it's like to create and manage my own cryptocurrency💲 Through this project, I gained a deeper understanding of tokenomics, and in particular, the key takeaways were the "approve" pattern for ERC20s and how contract to contract📝 interactions work

🎲 Dice Game: The second project I worked on was hacking a dice game program, which allowed me to identify vulnerabilities in generating randomness using the block hash and how this is a weak form of randomness.. This Speedrun taught me the importance of security and how even small flaws in code can have significant consequences🧑🏼‍💻

This concludes the second week, let's roll into the third week. Things are starting to level up a bit from here.

1. ⚖️ DEX Challenge: The third project I worked on was building a decentralized exchange (DEX), which allowed me to explore the concepts of DeFi and liquidity pools. Through this project, I gained a deeper understanding of how decentralized exchanges work and the role they play in the web3 economy. I also learned how to design and deploy smart contracts for a DEX, which is a valuable skill in the blockchain industry. Digged into the math of how Uniswap maintains liquidity📉

📺 A State Channel Application: The final project I worked on was a state channel application, which I had no idea about before starting the challenge. This project taught me the importance of scalability and how state channels can be used to reduce transaction costs and improve the user experience. Through this project, I gained a deeper understanding of how state channels work and how they can be used in different applications. I already have a couple exciting ideas that could leverage state channels and offload the load of Ethereum🕸️🕸️🕸️

Overall, the second and third weeks at the EthIndia fellowship were some of the most rewarding and fulfilling times of my experience. Through building these projects and learning about new concepts, I was able to significantly expand my knowledge and skills. I look forward to continuing my journey in the Web3 ecosystem and exploring new opportunities for growth and learning.  WAGMI🚀

I am writing to share my experience and progress during the first week of my ETHIndia fellowship. It has been an incredibly productive and exciting time, and I am already having fun learning and buidling ⚙️

The fellowship kicked off with a briefing from the Devfolio team to get a sense of what we would be working on in the coming weeks, and in the same meeting, I had a chance to meet and interact with other fellows and EIF3.0 mentors. On the same day, the very first workshop that I attended was by Austin Griffith, which gave us an introduction to Scaffold-ETH and SpeedrunEthereum. I have been following Austin for a while now, love his energy xD. Here's a playlist with all the workshops.

Throughout the week, I worked on the following two projects:

1. 🎟 Simple NFT Example: The project's goal was to delve deeper into NFTs and learn the fundamentals of Scaffold-Eth. Scaffold-Eth uses 👷‍♀️ HardHat under the hood to compile and deploy smart contracts. 🌟 The final app lets users mint, purchase and transfer NFTs.

Look it up at:

Github repo:

1. 🥩 Decentralized Staking App: This is a decentralised application where users can coordinate a group funding effort. If the users cooperate, the money is collected in a second smart contract. If they defect, the worst that can happen is that everyone gets their money back. The users only have to trust the code.

   Defi is one area in which I am really interested in and eager to learn more🦸

Look it up at:

https://speedrundisto1.surge.sh/

Github repo:

https://github.com/distroinfinity/speedrun1

Smart contracts📝 for both projects were deployed to the Goerli testnet, and the client sides were React apps with prebuilt Ethereum components and hooks, hosted on a public web server via Surge!

SpeedrunEthereum provides you with a Scaffold-eth starter repo, which can be used to tinker and build on top. In my opinion, it's a great way to get started and accelerate your solidity learning curve, as scafold-eth takes care of the housekeeping stuff for you.

Also, I received this cool SBT from the DevFolio team.🫡

I am really happy with my development over the first week of my fellowship and I'm having a great time. The environment is encouraging and welcoming, and I get the impression that I am part of a community where people are striving for the same thing. The experience is now motivating and enjoyable, and I am eager to see what the upcoming weeks will offer.
