Today a creator posts Twitter threads when a significant event (like a hack, etc) happens. They paste screenshots from blockchain explorers (like Etherscan, etc) to validate their findings. On top of that there are thousand people publishing analysis for the same event. 

For a creator, BlockBuster significantly reduces the time and effort needed from their end to create an engrossing story along with adding easy visual add-ons on top of everything.

For a reader, BlockBuster is one platform where they can find all social commentary related to a block or a transaction or a wallet (or any combination of these). Readers further get a chance to comment on these stories along with the ability to upvote or downvote a story. We will additionally allow readers to easily donate/gift to the creator of a story.

We will soon have a strong recommender mechanism in place wherein a creator will get transaction hashes and wallet address recommendations basis the text that they are typing for the post.

How many times have you executed N-transactions in a row to make the Dapps do something? (Approve ERC20, Swap, Stake, Unstake, Claim, etc). We know it's a bit annoying, but it becomes WAYYY MORE annoying in the case of multi-sigs!

Imagine calling the Safe signers after pressing Approve button on a Dapp because the Add Liquidity button won't be unlocked for you until sufficient signers sign and execute the approval transaction. And then waiting to receive the LP tokens the same way, and finally waiting for the staking transaction to go through. 

The community has built batching solutions to this but all of them either require a change in the frontend code of the Dapp, or some sort of wrapping smart contract. We realised it's just a UX problem, which can be mostly solved with some simulation and clever hacking :) 

**What does it look like for the users?**
Open the SafeBatcher UI, enter the walletconnect URL and "Start Recording". After that, they can execute the transactions as if they already had sufficient signatures for multi-sigs. **So YES, they don't have to wait for others to sign to unlock UI interactions likes Swap Button, Stake button, or Claim button!**. Once done with recording transactions, click "Stop Recording". That's pretty much it.

**How does it work?**
In short, SafeBatcher acts like a middleware which simulates the transactions on a fork (that's initiated when start recorded is clicked) by patching the multi-sig logic, returning the new state to the Dapp so that all the UX interactions can be unlocked. And more importantly, even not-so-tech-savvy users will be able to get those benefits.

In long, check this diagram :)

**All that's cool, but why use SafeBatcher?**

_**Our solution will be able to reduce the number of UI interactions needed by a factor of N! and the base gas cost by a factor of N-1**_

Have you ever wondered, why is it soo difficult to buy drugs? 
It's simple, drugs are bad for you. However, we don't just mean the typical addictive, chemical intoxicants that are often talked about like Cocaine, or Marijuana. We are referring to prescription medicines, that is regulated medicines that are painkillers, sleeping pills or anti-depressants. These are never easily accessible over the counter and this is because these medicines just like chemical intoxicants can kill. In fact, prescription medicines if abused can be just as if not more dangerous to one's health as the drugs in common parlance. 

The problem is so serious, in 2020, there was a reported 92,000 overdosing related deaths in the US alone. This problem has been exaggerated by online pharma. Covid was a book of online pharmacies springing up with many online pharmacies of varying sizes opening up. However, these pharmacies have poorly established systems for controlling prescription medicines. Getting these highly dangerous regulated substances off of these websites is as simple as uploading a picture of your prescription and choosing the medicines you want. This system with weak security and lack of interconnectivity leaves a lot of room for exploitation as patients can simply upload the prescription to multiple websites and get more bottles of these prescription medicines giving them the opportunity to be able to overdose on them, making this lethal and extremely dangerous for the patients. 

We intend to use the minting and burning capabilities of NFTs and web3 wallets to prevent this from happening. Our solution is simple, we let the doctor issue NFTs to the wallet of the patient. We use the ERC 1155 token format to be able to mint multiple counts of the same token for the quantity and then burn specific quantities as the patient buys them. On the online pharmacy end, the user would be asked to login with their M-Eth to be credentials to ensure the NFT for the medicine is in the wallet.

The need for certifications and official documents is required by most industries. Professional certifications can help individuals advance faster in their careers, especially in highly-specialised industries such as human resources, accounting, or information technology.

While not all certifications are created equal, they do assure professional competence in tandem with a professional degree or work experience. Fake certificates and documents can be easily produced which are hard to distinguish from the original document.

Thus it is very important to have safeguards in place to catch and prevent fraud in the earliest stage possible. Certification forgery is a very prevalent industry across the globe. Entire scams have developed around the fake degree racket with individuals, for a small price, being able to buy certificates for courses they never actually took.

To tackle this problem, the implementations available in the market today work by using image processing to detect any tampering. The problem with methods like these is that they cannot detect for sure whether it's forged or not. It's probabilistic in nature.

The project consists in designing and implementing the system which aims to tackle this problem by creating a secure blockchain-based solution that guarantees the authenticity of certification. The solution proposed is to allow the issuer of the certificate to create verifiable certificates on the blockchain. The project leverages non-fungible token technology to represent certificates on the blockchain. 

The token representation of certificates can verify the original creator of the token.

### Problem Context
The government has set a target that **30% of all vehicles be electrically driven by 2030**. For this aim to be realised requires that strong incentives be created for the manufacture, sale, and usage of electric vehicles. In addition, it is expected that the increased usage of EVs will substantially increase the usage of batteries to power them.

### Solutions
- ChargeSwap allows the user to seamlessly make a simple transaction to the system and get their discharged batteries swapped for batteries with maximum charge at the lowest costs possible implemented using MetaMask and Biconomy as a protocol layer.
- The product ensures the immutability of battery information storage by using the *IPFS (InterPlanetary File Storage) protocol* to store information such as age of the battery and its previous treatment in an immutable fashion, thus **removing the possibility of misrepresentation to increase price or lower cost of usage**.
- ChargeSwap, through the blockchain-based methodology, enables **programmable transfer of funds** as when the encoded conditions are met, funds can instantly and frictionlessly be transferred from source to destination. This is in stark contrast to the current system where payments go through separate routes and databases, and information asymmetries can arise. *Blockchain smart contracts cannot be modified once published, and their fund transfers cannot be intercepted.*
- It also enables **smooth integration of Web2 users** to the Web3 space by allowing for *Social Logins to create SmartAccounts* using Biconomy. This allows users to carry out transactions on the blockchain network without having to own a Wallet.  
- Usage of blockchain to store information on the sources of energy used to charge the battery may help inform choice to **incentivize usage of sources of renewable energy.**

web3fyi is a developer tooling platform simplifying blockchain based transactions to build intuitive user interfaces for dapp developers with a vision of becoming an L2 + L1 Block explorer and Analytics platform with open-source sdks to drive mass adoption to web3.

The current state of Dapp Interaction involves signing complicated transaction messages via wallets(usually browser extensions such as Metamask), and verifying these transactions on block explorers(eg: Etherscan) that is not very user friendly for non crypto users.

Complicated UX is very repulsive for new users that are already accustomed to the friendly UX of web2, by solving this UX problem, we can onboard more people to web3.

Existing block explorers and analytics platforms are mainly targeting web3-native users. Their platforms are still very difficult to understand for someone very new to web3(and usually has a higher learning curve).

In the Indian Market, people love negotiating, so why not let the people negotiate while acquiring informal credit? These P2P Informal Lending Transactions carry a huge risk, we plan to curb this problem by providing a platform that ensures the same level of security as formal credit but with P2P lending. We have adopted the concept of Credit Score and applied it to the Web3 ecosystem by providing a very complicated and thorough financial check of both the lender and the borrower so that we can give both parties peace of mind that their coins are safe. As the web3 revolution picks pace we plan on targeting the common users who need to be educated about the secure ecosystem of ether and how it can change their life for good.

Account abstraction has for a long time been a dream of the Ethereum developer community. Instead of EVM code just being used to implement the logic of applications, it would also be used to implement the verification logic (nonces, signatures…) of individual users’ wallets. Below are some of the features that can be possible using account abstraction:
- Multisigs and social recovery
- More efficient and simpler signature algorithms (eg. Schnorr, BLS)
- Post-quantum safe signature algorithms (eg. Lamport, Winternitz)
- Upgradeability

It is possible to do all of these things with smart contract wallets today, but the fact that the Ethereum protocol itself requires everything to be packaged in a transaction originating from an ECDSA-secured externally-owned account (EOA) makes this very difficult. Every user operation needs to be wrapped by a transaction from an EOA, adding 21000 gas of overhead. The user needs to either have ETH in a separate EOA to pay for gas, and manage balances in two accounts, or rely on a relay system, which are typically centralized.

All of these problems prevent / deter users from exploring the Web3 space.

Problems faced by users:
- All the personal data of an individual like aadhar, bank details, passport, degree, office Id, etc is distributed on several different platforms like digiLocker and various bank apps which is an inconvenience for the user to manage.
- When organizations wish to get information from these institutions about the users, it may take days to weeks to contact the representatives and receive the necessary data.
- For example, if an employer wants to collect data about a student from his/her college, it may take a lot of time to contact the institution and get their data.
- There's an obvious issue that any data provided by an individual can be forged and verifying it from the respective institution could be troublesome.

Solution offered by VeriFi:
- We provide a platform for the organization to upload the data of a particular individual directly to a decentralized network like IPFS. This also gives the user a single place to access all their personal information and forgoes the need to deal with several data storage platforms.
- When the data is uploaded by the organization to IPFS, the encrypted data is signed by the Organizations' private key and is put on the blockchain. A corresponding NFT can also be minted by the organization mapped t the user's wallet address. Anyone can now use the signature and public key of the organization to verify that the data of a user is indeed verified by the issuing organization.
- Since all the data hashes and signatures are stored on-chain, the data and verification became decentralized and immutable, and seamlessly available for any person to verify.

## Backstory
Today, most developer communities and organizations (including DAOs) use GitHub to host their projects. GitHub is a centralized organization providing limited support for web3 native values; hence, the data could be lost.

Here's an example of **Tornado Cash**:


![Tornado Cash](https://i.ibb.co/br33sn9/Screenshot-2022-12-04-at-8-33-55-AM.png)̌

To resolve, this issue there are tons of other projects built on the web3 stack that provides an alternative UI and architecture to host projects. But guess what people still don't use them. Even Tornado Cash continued to use Github after that happened.

The reason is that the features and comfort GitHub (or web2 solutions) provide is incomparable to the new immature emerging solutions.

## Our Idea
Therefore, we thought to create a continuous integration to store the projects on GitHub to a decentralized network like Filecoin using Web3.Storage. This basically backs up the project onto the decentralized network every time a new commit is pushed to the branch. And the source of truth is moved from Github to spread across the network. 

Additionally, we are indexing the CIDs with important metadata like contributor, commit message, etc. that will help in:

- Having access to the full Github tree and contributions history
- Providing on-chain identity to the developers contributing to the public repositories (Future Prospect)

Therefore, with Sadaiv CI developers can work with the comfort of web2 solutions like GitHub yet remain to ensure the ownership of their project and contributions is not in the wrong hands.

All the details on LinkedIn are filled by the individual himself and there is no way to prove that the details are correct.
Thats were SmartVerify comes into the picture. We are visioning of a platform where a person will have all the information which would be helpful for them in Academics and Professional Career. But in this, the user won't have rights to edit it themselves. Suitable and Trusted organizations would issuing those documents and details to the user's profile.

One such flaw is what we aim to solve.

The flaw is a LACK OF A RECOVERY SYSTEM of assets from decentralised wallets/exchanges and there is absolutely no way to recover them should you lose your private key.

That's where Dwill comes in.

We transfer all funds to the recovery account provided by the user while creating the lock.

Details we need :

1. Public address of recovery account
2. Time by when transfer should happen if we find it inactive , Inactivity : Tranfer made by user's account.

This solved both the cases :

A. If unfortunately something happens to the user 
B. If user forgets the password

The aim is to do the same thing to compute what IPFS did to storage. Essentially decentralizing the compute layer of applications among the network provides censorship resistance along with the fact that the same function evaluations between different applications can be shared. For ex., a neural network relies on many matrix multiplications and convolution. By making these primitive operations decentralized and shared among the network nodes, we can significantly improve the performance of the applications using them. 
Another use case can be lets say the cloud providers decide to not allow a particular application to be hosted on their platform, this will be bad for humanity and can be solved by having a decentralized compute layer along with the already existing decentralized storage solution (IPFS).

Purple Pay is built on Polygon for instantaneous transactions, fees that are fractions of a penny, and a net-zero environmental impact.

The original use case for cryptocurrency was Bitcoin- self-sovereign money. Bitcoin’s core ability to make cross-border payments happen without an intermediary was revolutionary.

Despite a decade of innovation in the space, it has continued to be a speculative asset with limited real-world usage. The ability of people to transact with each other ensures we have access to products, services, and an incentive for people to build those products/services.

Payment infrastructure, ie. the ability to allow people to send and receive payments is a fundamental need. We believe crypto payment infrastructure will be pivotal in helping people get access to credit.

**Here is how people can use Purple Pay:**

1. **Send and receive crypto:** Create unique links to receive funds in your wallet 
2. **Accept Payments:** Merchants can accept payments now through Purple Pay API 
3. **Scan and pay:** Clean payments with scan and pay infrastructure, no more lengthy wallet addresses
4. **View reports:** Manage payments and view reports at the click of a button. No need to spend time evaluating block explorer transactions

To make it easier for folks to make payments going forward we want to integrate Biconomy’s relayer protocol along to make transactions gasless. We also seek to provide multi-chain and multi-coin support by using Etherspot’s SDK and LiFi’s bridge API.

Our belief is that most governments have a strong anti-crypto stand because they see it as a way for money-laundering activities and other tax evasion practices. 

Our vision with Purple Pay is to solve regulatory concerns by creating a KYC-compliant protocol through ZK-enabled-decentralized identity that adheres to money-laundering regulations globally. At the same time, it does not reveal the identity and other details of the people making those transactions.
