State channels or state channel solutions are what Cardano is in dire need of right now. Due to the complexity of handling the state of the Eutxo ledger, creating a perfect state channel for Cardano will take a long time. It can be seen as Hydra, in order to create a state channel that is not only fast, but also has to be synchronized with the entire Eutxo ledger state from all hydra heads, Hydra must be designed as an isomorphic state channel, not an common state channel like state channel that running on blockchains using the Accounting ledger model. Therefore, more solutions are needed to create new state channels running on Cardano before a perfect Hydra is launched on the mainnet. Perun channel has been developed based on the design of state channels running on blockchains using the Accounting ledger model. In the solution described by the proponent, Perun researched and deployed on Cardano will be a cross-chain state channel. This is a very cool idea although difficult to implement like the synchronization of account states of the Accounting and Eutxo ledgers, the difference between Full turing programming language (Solidity) and Non-Turing programming language (Plutus). But that's the plan for the future, and for now building a basic state channel is a pretty cool solution. And it also suitable for the challenges set by the "scaling solution" challenge.

This is a potential project, it implements Perun Channels for Cardano and thus enables P2P transactions at unlimited scalability and with cross-chain potential. If the project is successful, there will be a state-channel-based scaling solution available for Cardano. State channels are particularly viable for use cases that require low latency transactions as, for example, in gaming or micropayment solutions.

Creating a common channel for Cardano is a problem that needs to be solved and it is directly related to this challenge. Deploying the Perun channel for Cardano that allows P2P transactions is a necessity. It effectively solves the challenge if this project is funded it can provide a good impact on the community and help Cardano grow more.

Cardano does not have a deployed state channel framework, yet. The Hydra protocol is still WIP. We implement Perun Channels for Cardano and thus enable P2P transactions at unlimited scalability and with cross-chain potential. Built-in protocols are better when. . Build execution solution (Perun Protocol / Custom transaction logic / Cross-chain transactions / Implementation) and synergies with Hydra team. The proponent mentioned 3 challenges with solutions (Challenge 1: Steep learning curve / Challenge 2: Availability of Go client / Challenge 3: Availability of external libraries).

This proposal solves the challenge relatively effectively. The authors implement Perun Channels for Cardano and thus enable P2P (peer - to - peer) transactions at unlimited scalability and with cross-chain potential. This provides a lasting foundation for Cardano's growth. This also contributes to forming one of the effective solutions for the “Cardano scaling solutions” challenge. In this proposal, we see the presence of Perun protocol - an instance of a state channel protocol that results from a series of renowned research papers (EUROCRYPT, CCS, S&P). I will talk about some impacts of the proposal to Cardano as below: Features of Cardano: Cardano helps solve the three big problems of Blockchain, including: • Scalability (scalability). • Interoperability (interoperability). • Sustainability (sustainability). Cardano's scalability consists of three elements: • Transaction Per Second (TPS): Cardano uses Ouroboros consensus algorithm, belongs to the Proof of Stake group. • Network: To increase the bandwidth of the network, Cardano uses RINA (Recursive Inter-Network Architecture) technology to divide the network into many subnetworks, and these subnetworks can interact with each other if needed. • Data Scaling: To reduce the data size of each transaction, Cardano is paying attention to two solutions: Subscriptions and Sidechains. Proposing the statement “If the project is successful, there will be a state-channel-based scaling solution available for Cardano. State channels are particularly viable for use cases that require low latency transactions as, for example, in gaming or micropayment solutions. Moreover, Perun channels will potentially enable cross-chain transactions in the future.” This has positive effects on Cardano's building and scaling in the long term. Therefore, the proposed solution is effective and solves this challenge.

Proposal wants to implement Perun channel for Cardano. Cross-trading helps Cardano increase scalability. Proposal is an easy-to-understand description and has a detailed solution to the challenge. Besides, the team also needed to remind some risks and have solutions for those risks when the project is implemented. However, from the proposal's schedule sheet, I am not confident that the proposal will succeed at all.

I strongly agree with this proposal. The development of the Perun channel for Carnado is necessary. Perun's influence will grow. Because now what people need when transacting money is a fast, safe, no-fee and high-security transfer mechanism. Especially when trading cryptocurrencies, fast transaction speed is absolutely essential. And Perun meets that. Besides, Perun also eliminates the third party when transacting, so it will save time and cost for the parties. I really appreciate this project. Because it allows P2P transactions with unlimited scalability and cross-chain potential.

I have added this cut and paste disclosure to some of the more technical proposals so the voters and proposers have a basic understanding of where my assessment is based. I am assessing the merits of the proposal - not the technology! While I started carding IBM mainframes in the 70's and had some understanding of basic, fortran, linux, c, c++ and am currently in the Prisim Pioneer class and did a stint as an IT tech I am not an engineer, programmer or developer. I have done reading on the tech stuff being proposed where I could find stuff, cause of my geeky curiosity, BUT I am only assessing the proposal. Please DYOR on the tech due to the potential ramifications to the Cardano network if we adopt one of these technologies.

Pre-digest: State Channel - a) general form of payment channel; b) process of Tx's with one another, off chain; c) channels off chain and private. PERUN.network = off chain framework that supports real-time payments, claiming unlimited scalability and provable security. ERDSTALL.dev = L2 blockchain allows massive scaling on Ethereum. GO = aka Golang is an open source programing language designed by Google. GO CLIENT = graphical interface to GO servers and Go programs.

This proposal is extremely well written and in my opinion meets the Challenge objectives. The objectives it meets include: Hydra add ons; State Channels; Borrowing from other blockchains; Novel scaling solutions and Research.

Perun has already implemented channels for Ethereum, Cosmos and Polkadot. It proposes to implement Perun Channels for Cardano which would enable P2P TX's with unlimited scalability and cross chain potential. This will require research in part due to: Perun account based protocol translation to eUTXO; Perun library is written in Go however, a Go Client is not available on Cardano; potential need to build an adaptor between Go and Cardano; availability into libraries to verify signatures in Cardano smart contracts and information encoding in off chain client and then how to encode it in smart contract logic. These are all areas of topic and objectives in the Challenge.

Success and key metrics according to the proposal is to demonstrate (at a minimum) the feasibility of Perun channels on Cardano. This would open space for APPS that need scalable and low fees e.g. games and micropayments. In a balance of transparency to efficiency the team proposes to push progress to a public repository.

The Perun team brings a lot of experience to this proposal that will look at building state channels in the Cardano ecosystem. This will help to create p2p interactions and massively scale things on the proposed state channel which would be very impactful for users of the channel.

State channels are definitely useful for Cardano app development.

As a community advisor I would also appreciate exposing this technology to wider CA audience.

The proposal is aligned with the challenge as it intends to build a state channel for Cardano. State channels enable low latency transactions. The proposal also calls out that it will potentially enable cross-chain transactions in the future.

The challenge asks for proposals that will help Cardano scale, to secure Cardano main chain is not overloaded as new protocols in DeFi, NFTs and gaming are being released.

Challege encourages proposals within the following scalability topic areas:

• Rollups (e.g. zero knowledge rollups, optimistic rollups)
• Sharding
• Sidechains
• State channels

The proposal description promises to deliver an alternative state channel and if it is developed it will be of great help to Cardano's main chain as it will involve off-chain transactions. I strongly agree that this proposal effectively addresses the challenge and rate Impact to 5

To evaluate the success of this project, I think you need to add the information that I mentioned in the previous section (team profile, clear budget allocation). I also appreciate that you have identified the risks and challenges that will be encountered during the implementation of the project, as well as how to solve it. It is a solid foundation that helps your project to work for a long time. I have looked at all attachments and visited the github link you provided, really this is a very potential project, I hope in the future this project will be accepted. If implemented successfully, it will certainly bring great value to the Cardano ecosystem.

The proposer provides a github source to test the programming and build of Perun. I can understand that will track commits that will be pushed to this github source. However, there is still the issue to track the commits pulling activities according to the timeline. Reporting of funded proposals to Catalyst is monthly. So, In order for the tracking process to be really effective and help both Catalyst and the proposer, every detailed plan in the roadmap should be presented in a monthly or weekly timeline. This is also the reason why I suggest the proposer provide a more detailed roadmap. I hoped that the proposer can do this in the case the proposal will be funded. How successful was the project? Although the proposer has not described it thoroughly, in my opinion if the Perun state channel in the basic version is completed according to the proponent's commitment, this will be a great success. In the context of metaverse and Nft projects exploding on the Cardano ecosystem, the presence of a state channel will greatly increase the expansion of Cardano.

It's a great idea to push my progress publicly to the archive so that everyone can track the author's progress. This proposal has a very distinct KPI I agree with what they recommend, which makes tracking the proposal after successful funding pretty easy. With their team's roadmap proven possible via the Perun channel on Cardano and they also integrated development components directly in the Perun Framework I see great potential in their future. This will provide us with complete documentation and a complete focus on audibility, we will know exactly what the results are from the project. I believe that if this project is funded, they will soon succeed. This project is brand new and unfunded.

The success of this project was being able to demonstrate the feasibility of Perun channels on Cardano, thus opening up the space for applications that require low-fee peer-to-peer transactions, such as games. or micropayment solution. The success of this project was being able to demonstrate the feasibility of Perun channels on Cardano, thus opening up the space for applications that require low-fee peer-to-peer transactions, such as games. or micropayment solution. This is a new project.

Information is provided in an overview, not specific and detailed for different categories. Therefore, in the process of finalization and cooperation between Cardano and the author of the proposal, it is necessary to clarify to create transparency in the cooperation process between the two parties. Implementing the above suggestion will help Cardano to open up the space for applications that require scalable and low-fee peer-to-peer transactions. This brings the success of the project as well as the sustainable development of Cardano.

The goals listed are pretty clear. But not really specific details. I think it is necessary to indicate the minimum KPI to be able to take the next steps in the plan. The project offers openness and transparency of its development progress and has a mechanism to track key features in issues to maintain efficiency and transparency. I very much agree with this. Because when there is such a public mechanism, it will help people easily track and capture information. And this helps to increase people's trust when using Perun Channels.

I don't understand how the proposal will evolve over time. It would be great if you suggested having a few more KPIs and budgets broken down over time. Investors, the community will be able to easily test and measure the development and success of the proposal. Increase project transparency. That will be a tough turning point for your new project.

I rated this section as 5 - Strongly Agree, even though the proposal does not provide the traditional KPIs some Advisors and Voters expect. The team has demonstrated a principled level of Transparency in their proposal and has demonstrated success on at least three other chains.

In the Proposal they have included: a) Roadmap ; b) Plan with Timeline; and, c) a pledge to push their progress to a public repository, track major features and issues ( keeping a balance between efficiency and transparency); and, that WIP code will be visible in the commits of merge requests.

Therefore based on the above rationale I assess that this proposal and ensuing project will be assessable

The only major lacking in this proposal is details on how the project will be executed and milestones they will be planning to report out on. They are planning on making their work/findings public through public repositories, but no details as to how and what the structure of the information that will be made available are given.

The source code repository, and clear vision of Perun implementation should make it easy to audit that the project is interoperable with the other implementations.

However, it would be nice to see actual reports in terms of functionality derived, and demo applications shown.

The proposal says that progress can be tracked in its public repository. Work-in-progress code will be visible in the commits of merge requests. The proposal indicates good understanding about the problem and solution. At the same time lack of break up of deliverables and milestones can hamper auditability.

The proposal contains a clear roadmap and description of expected delivery. The project will provide full insight into how the development is going on in a public repository. The proposal is a clear description of a solution that will be positive for Cardano and which is completely in line with the challenge description

I strongly agree that this proposal provides me with sufficient information to assess the progress in attaining its stated goals and rate Auditability to 5
