This proposal presents a blockchain that uses a modified Aura in which blocks are sealed. We then implement an encryption-to-the-future (EtF) scheme, where messages can be encrypted for arbitrary slots and epochs in the future. Our proposal consists of a runtime, which modifies Aura and introduces a new pallet to enable the identity based cryptosystem (IBC), a light client, and an SDK which handles synchronization with the blockchain, slot scheduling, and offchain encryption and decryption functionality. In essence, this presents a simplified flavor of 'timelock encryption', though sacrifices full-decentralization for ease of implementation and feasibility (for the time being).

Due to a combination of increased population and changing housing needs, there is global housing crisis. According to the UN, the global population is set to reach over 11.2 billion by the year 2100, therefore 2 billion new homes are required in the next 80 years. 20% of all housing is built by small to medium sized real estate developers but access to finance through traditional banks and other financial institutions is complex, time consuming and expensive.

There are multiple ways to implement the logic in substrate i.e using pallets or ink smart contracts, or even writing solidity code and compiling it to WASM with the help of a solang compiler. We have to benchmark the performance metrics of the logic implemented using each of the above methods. We have already benchmarked the storage performance(basic data types) of each of the implementations as part of Milestone 1 and 2. Now, we will benchmark CPU-intensive logic, events emission and cross-contract calls across all the four implementations. We hope this will help new developers in deciding the best approach to implement the logic.

Stylograph is a framework aimed at enhancing the functionality of substrate-based chains in the Polkadot ecosystem with plugin-like functionality.

The adoption of any technology depends on the accessibility and ease of use to both the maintainer and user, blockchain or distributed ledger technologies are inherently a lot difficult to understand and maintain, so we have to build tools to make the process much easier and painless. In the case of Polkadot's substrate based smart contract development we have Ink! playground which helps smart contract developers to prototype and test it before deploying on the parachain in a Sandboxed environment with having to do time-consuming setup of dependencies and also with ability to set up a local environment to do development.

The key objective of this grant is to build a tool which allows to compare contracts performance and to track its regressions. Subject of comparison are solidity, and ink! contracts running on parachains (pallet-contract and pallet-evm). Tool will be integrated with CI and running each night, generating measurements data and providing its visualizations.

We can most certainly agree that the future is multi-chain. As such, it is not uncommon for users to hold multiple accounts across various chains for reasons such as distinct address formats and security benefits. However, this practice presents a challenge in managing multiple addresses. Adding to the complexity is the need to verify the address of the intended recipient, as it may have changed over time.

Runtime Pallets are modules for writing the business logic of blockchains in Substrate (a Rust framework for building blockchains). These are usually concise pieces of standalone code with relatively few dependencies and clear specifications, hence tractable targets for performing static analysis and verification. The code quality of a runtime pallet is crucial, as even minor defects can result in major exploits like DoS attacks or the stealing of funds by a malicious party. A static code analysis can help to automate the auditing processes and prevent introduction of defects throughout the software life-cycle.

We have wrapped all XCM pallets from compatible nodes into simple patterns from which it is easy to create XCM calls. As an example, we provide the image below.

We aim to resolve the challenge of identifying the optimal technical architecture for a Dotsama-wide on-chain NFT domain service and how XCM can be leveraged to achieve this. Thus, before we can build an XCM-based domain service in ink!, we will need an in-depth understanding of the XCM technology, currently available standards, and their limitations. Once we have developed a deep understanding, we will identify all potential levels of integration, assess their feasibility, and finally propose the technical architecture of an XCM-based domain service.

Interstellar is more than a wallet, we have designed a novel secure access layer for web3 managed with a blockchain that register mobile hardware/secure elements/TEEs to protect transaction with a strong multifactor authentication (based on hardware and software computation privacy scheme i.e. garbled circuit).

The Interoperable State Machine Protocol, or ISMP for short, is the product of our research into state proofs. We show that state-proof based interoperability is possible and more efficient as the messages no longer need to be routed through the relay chain and can be exchanged independent of it, while still maintaining the same level of trustlessness and security. This protocol allows not just for messaging but also state reads of other parachains in a trustless and secure manner.

This project provides a more flexible governance framework for a large number of small groups with common characteristics. It allows developers to create behavior templates based on this set of governance solutions in the simplest way possible, However, the origin of each specific behavior in the template completely depends on the users in the population (here we can call it the instance), that is, different user groups using the same type of template can have different Origin combinations. This can be very useful, especially for products like LISTEN and KICO that have a strong group nature. Rooms are a template, multiple assets are a template, ico are a behavior template.

Through our platform, businesses can easily fund surveys using digital tokens or NFTs, streamlining payment processes and ensuring faster and more efficient transactions.

Inspired by the success of STEPN, we have great confidence in Web3 applications combined with life scenarios. Because to let the majority of users enter the Web3 world, the interactive way of life scenes is the easiest entry. So we started from the fitness field and developed a Web3 smart fitness application, allowing ordinary users to pick up fitness equipment, training daily + GameFi, and gradually understand how the Web3 world can bring them more value and fun.

This project aims to introduce binary merkle tree's as a first class citizen in substrate. There is a large demand for the usage of binary merkle tree's, especially in the context on zero-knowledge circuits where substrate's native patricia merkle tree is not well suited. The demand for the existence of binary merkle tree's can be evidenced by reviewing grant applications, many of which are implementing their own binary merkle tree on top of substrates native patricia merkle tree. This is an inefficient solution and not production ready. This project will introduce binary merkle tree's as a child tree such that developers can create and interact with the binary merkle tree's via a runtime api. We are interested in delivering binary merkle tree's such that we can utilise them in the future for zero-knowledge focused substrate projects.

Hex Space Social Graph is heavily inspired by Five Degrees protocol implementation 5degrees Five Degrees propose a simple entity data ownership protocol and use the protocol to capitalize these core data. To make the protocol simple enough, permission-less, and composable, we choose to build the protocol under the existing ERC-1155 standard. Compatible with the ERC-1155 standard, meaning it will be easily implanted into any protocol or business of Web3 that supports ERC-1155. The NFT generated in the protocol can be traded in any NFT market, also any smart contract that requires user relationships can track this data on chain. Any application that supports ERC-1155, can easily integrate this protocol.

It will also be compatible with Redspot (if redspot was used for compiler projects, you could just leave most of the things). We have some updates on our team, so check them out. And also, we did more work on Milestone 1 than we thought, so now it'll be easier to add new features to the project, so we considered to reestimate our time.

subalfred's goal is to become an all-in-one Substrate development toolbox.

Go is a modern, powerful, and fast programming language focused on simplicity (abiding by the KISS principle: "Keep It Simple, Stupid") and gaining a lot of popularity among software developers nowadays. It is future-proof and stable, being backed by Google and used in many of their software. It has great support for network programming. All of these reasons make Go an ideal candidate for implementing an alternative framework for blockchain development targeted at newcomers. Furthermore, the waters have already been tested! Gossamer is a recent effort towards implementing a comprehensive Polkadot Host in Go, which should make implementing the Runtime easier. It is arguable that other frameworks for building Blockchain networks (e.g Cosmos) have gained significant adoption due to the lower barrier for entry (compared to Rust).

ISO-8583 is the international standard for card based payments and transactions. It's used everywhere from ATMs to Merchant point of sale terminals. Supporting international standards could help smooth the connection between crypto and traditional financial institutions. Further simplifying matters is that several rust crates exist supporting the packing and unpacking of ISO-8583 data streams.

Perun state channels enable fast and cheap transactions with arbitrary transaction logic on and across blockchains. They are based on peer-reviewed research that has been published at top conferences and is being implemented in the form of the open-source library go-perun written in Go. One of the library's main features is its blockchain-agnostic design, which means that the core library components do not depend on a concrete blockchain implementation, but are rather implemented against abstract interfaces. This allows to integrate arbitary blockchain backends with the go-perun library. Currently, we have backends for Ethereum, Cosmos, and Polkadot. The development of the Polkadot backend was supported by the Web3 Foundation.

This parachain supports confidential transfers and privacy preserving smart contracts on the mainchain based on the plonk. To support privacy, the traditional blockchains need to implement L2 solutions, complex contract logic or depend on centralized security assumption. The L2 technologies often sacrifice the usability, the complex contract logic cost too much gas and development workload, and the centralized security assumption force us to believe someone you have never met before. As the solution for these problems, we are going to implement parachain supporting privacy on mainchain and depending on only cryptographic hardness assumption. The documentation is here.

This middleware solution listens to events from blockchain applications and propagates them to a registered pool of MQTT brokers. The broader architecture consist of parachain from which the middleware listens for the events.

An increasing number of websites require access to the Polkadot extension with a growing ecosystem. By allowing access to the extension, websites (naturally) can see the addresses that are contained in the extension. This imposes a big risk to privacy, because malicious actors could create lists about which addresses belong to one entity and, in the worst case, even link it to real-world identities (if at least one address is linked to an on-chain identity). A feature to prevent this is currently the "hide" button on single addresses, which prevent websites from seeing that address. However, it is currently cumbersome to handle that feature. The idea of this project is to extend on that feature and include a few QOL functionalities to make it easier for users to protect their privacy.

Typesafe contracts' descriptions can be generated automatically by a script, taking a list of ABIs as an input, giving usable TS type definitions and even runtime code as its output.

XBI will be an XCM-based Binary Interface that extends the XCM-protocol to enable smart contracts calls, while receiving execution results back to the source Parachain.

This Proposal is based on https://github.com/w3f/Grants-Program/blob/master/rfps/scale-codec-comparator.md. To date, there are more than 9 published implementations of the SCALE Codec. Since each is implemented by a different team & the reference implementation still introduces small fixes, it would be beneficial to compile a table of feature-completeness. This would provide (some) assurance that the implementation in a given language is safe & sound to use.
