+## Intro
+
+Hi all, I [closed out](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/314#note_18262) my previous [Seraphis Wallet PoC CCS](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/314) after consuming all the hours. There are additional tasks I would like to work on. For background on this CCS, please see the links in the previous sentence.
+
+In the last CCS period I decided that an actual wallet proof-of-concept is too ambitious. My more modest/realistic goal is to complete the Seraphis library so wallets can be (relatively) easily built.
+
+
+## Continuing work
+
+Here are the tasks I hope to finish by the end of this CCS (a continuing refrain, maybe some day my list will have no more items). As before, these will be implemented in my [seraphis_lib](https://github.com/UkoeHB/monero/tree/seraphis_lib) branch.
+
+- Legacy/Seraphis integration so old cryptonote-style enotes can be spent in Seraphis transactions.
+- Seraphis-style coinbase transaction type.
+- Test out tevador's [x25519 library](https://github.com/tevador/mx25519) for enote ECDH instead of ed25519, which may speed up enote scanning by a non-trivial amount (>10%). (big thanks to @tevador for putting that library together)
+- Miscellaneous code cleanup (mostly update/add comments, cleanup TODOs).
+- Update the [Seraphis draft](https://github.com/UkoeHB/Seraphis), which I have not touched for 6 months.
+
+As usual, I will also lump all the miscellaneous Monero R&D tasks that I work on into this CCS (e.g. in the last period I did more review/work on multisig security patches, among other things).
+
+
+## Funding
+
+- Rate: 50 USD + 0.2 XMR
+- Hours: 12 weeks @ 20hr/wk = 240hrs
+- XMR equivalent: 48 + (50\*240)/USD\_EXCHANGE\_RATE XMR
+- USD\_EXCHANGE\_RATE: set from 14-day EMA on a major exchange
+  - 163 USD/XMR at 0045 UTC 08/18/2022 w/ 14-day EMA on Kraken -> 122 XMR total
+
+If I require more time, and the community supports it, then I may make another proposal to extend the hours.

+
+Hi all, I [closed out](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/369#note_21022) my previous [Seraphis Library Work 2 CCS](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/369) after consuming all the hours. There are additional tasks I would like to work on. For background on this CCS, please see the links in the previous sentence.
+
+In the previous CCS I refined the seraphis library to a satisfying state. It can now be considered in 'final draft' form.
+
+
+## Continuing work
+
+Here are the tasks I hope to finish by the end of this CCS.
+
+- Update the [Seraphis paper draft](https://github.com/UkoeHB/Seraphis). I will split the current draft into two papers, one focused on the core Seraphis abstraction and the other focused on the current implementation using Jamtis. My goal is to get those papers to a place where I can collaborate with (as yet undetermined) security researchers to add proper security analysis.
+- Support the seraphis migration workgroup with focused architecture design work, and possibly contribute development work to that effort.
+- Build a demo for a secure and efficient escrowed market using Monero 2-of-3 multisig with the seraphis library.
+- As usual, participate in ongoing Monero R&D discussions and tasks.
+
+
+## Funding
+
+It has been a year and a half since I opened my first Seraphis-related CCS. I feel I have reached a level of proficiency with Monero research and development to justify asking for a raise of `10 USD + 0.1 XMR / hr` in this CCS.

+
+## Intro
+
+Hi all, after some encouragement I decided to request funding for my ongoing work on Seraphis. Specifically, funding for future work on the Seraphis C++ proof-of-concept that I have been developing since the second week of September.
+
+My goal is for this code to be 95% production-ready. It is appropriate to get large pieces of code funded if they have a strong potential to be merged into the master branch.
+
+
+
+## What is Seraphis?
+
+[Seraphis](https://github.com/UkoeHB/Seraphis) is a next-gen transaction protocol abstraction, which means it defines various high-level rules for a concrete transaction protocol. RingCT can be thought of as the current tx protocol abstraction, even though [the RingCT paper](https://web.getmonero.org/resources/research-lab/pubs/MRL-0005.pdf) specified concrete proving structures directly without abstraction.
+
+The main innovation of Seraphis (and [Lelantus-Spark](https://eprint.iacr.org/2021/1173), a very similar protocol developed independently) is using _only_ simple commitments-to-zero for showing that a transaction input (an output being spent) exists in the ledger. This allows proofs about key images to be independent of membership proofs, which means one-time addresses and key images can be creatively designed. In particular, it is possible to avoid one of the main drawbacks of [Triptych](https://eprint.iacr.org/2020/018), namely a key image construction that makes multisig [much more complicated](https://github.com/cypherstack/triptych-multisig).
+
+Seraphis has other potential benefits over RingCT and Triptych (depending on concrete design choices):
+- membership proof delegation (allows transaction chaining, offloading proof construction to third parties, improved indistinguishability of multisig tx [construct membership proofs at the last minute to avoid leaking timing details], allows the 10-block lock time to be somewhat ignored when transacting with a trusted party)
+- multi-tier wallet permissions (e.g. a view-only wallet that can detect spent outputs, a view-only wallet that can see received outputs but not their amounts)
+
+The main costs of Seraphis compared to Triptych are:
+- more implementation effort
+- all users would have to generate new addresses from their private keys (don't need new private keys, seeds, or wallets); all old addresses would become unusable
+    - **note**: Replacing old addresses is an opportunity to deprecate 'normal addresses' in favor of 'subaddresses' only. A uniform address format would simplify UX and various implementation details.
+
+
+
+## PoC
+
+**Scope**: I am working on a core component library for Seraphis, which includes proof structures, transaction structure and validation, core transaction building pieces (both normal and multisig transactions), unit tests, performance tests. The scope is similar to the `ringct/` subdirectory. I currently do not plan to touch the `wallet/` subdirectory.
+- The scope also extends to my efforts to performance test different variants of Seraphis, and Lelantus Spark. However, only the main parts of Seraphis will get high-quality attention until performance results are available.
+
+Building a new transaction-builder component library is a good opportunity to both re-imagine how to architect component versioning (i.e. instead of spaghetti conditionals, which are rampant in some parts of the codebase after 13 hard forks), and to add various things from my wishlist.
+
+Ultimately, I want to include the following in my PoC (found in the MRL and Monero GitHub Issues linked below):
+- reorganized tx semantics (`tx_supplement` takes some stuff out of the `tx_extra`)
+- view tags
+- enforce 1 tx pub key for 2-out tx, 1 key per output for >2-out tx
+- enforce sorted-TLV in the extra field
+- Janus mitigation (one way or another - depending on the address scheme chosen)
+
+
+### PoC: current progress
+
+The PoC currently has:
+
+- mock-up of RingCT with CLSAG (for performance comparisons)
+- mock-up of Triptych (for performance comparisons)
+- concise Grootle proof (with 'aggregation coefficients', like found in Triptych)
+- plain Grootle proof (without 'aggregation coefficients', like found in Lelantus-Spark)
+    - **note**: The guys at Firo theorize this should have faster verification than concise Grootle proofs (using 'small scalar weighting'), but in my tests it is slower. This may be due to a limitation of Monero's crypto library, which contains no optimizations for small scalar EC multiplication, so future improvements may be possible.
+- Seraphis composition proof
+- unit tests for all of the above
+- tx mock-up performance testing framework
+
+
+### PoC: TODO
+
+My immediate plans for the PoC include:
+
+- core multisig functionality in Seraphis composition proof
+- mock-up of 4 different Seraphis variants
+- mock-up of Lelantus-Spark (probably... it turns out coding complex cryptographic algorithms like advanced signature schemes is a lot of work)
+- unit tests for all of the above
+- comprehensive performance testing of all tx protocol mock-ups
+
+Once performance tests are complete, I will take a break of 1-4 weeks to finish the Seraphis paper. Then, after making various design decisions to narrow down the optimal tx protocol and address scheme (based on discussion in the Monero community - primarily IRC channels #monero-dev and #monero-research-lab), I want to add the following to the PoC (I will probably make a new branch for this, and cut out all the extra stuff from performance testing).
+
+- mock-up of Seraphis addressing framework
+- mock-up of Seraphis transaction builder framework (with multisig)
+- the wishlist from [above](#PoC)
+
+
+
+## Past and current Monero work
+
+- [Seraphis paper](https://github.com/UkoeHB/Seraphis): in-progress
+- [Seraphis PoC branch](https://github.com/UkoeHB/monero/tree/seraphis_perf): in-progress
+- [ZtM2](https://web.getmonero.org/library/Zero-to-Monero-2-0-0.pdf): complete
+- [ZtM1](https://web.getmonero.org/library/Zero-to-Monero-1-0-0.pdf): complete
+- [MRL issues](https://github.com/monero-project/research-lab/issues/created_by/UkoeHB): many are active/open (the fee issue is [close to merging on master](https://github.com/monero-project/monero/pull/7819))
+- [Monero issues](https://github.com/monero-project/monero/issues/created_by/UkoeHB): tx semantics proposal is open
+- [Monero PRs](https://github.com/monero-project/monero/pulls/UkoeHB): multisig address-generation rework is open
+
+
+
+## Funding
+
+- Rate: 50 USD + 0.2 XMR
+- Hours: 6 weeks @ 40hr/wk = 240hrs
+- XMR equivalent: 48 + (50\*240)/USD\_EXCHANGE\_RATE XMR
+- USD\_EXCHANGE\_RATE: set from 14-day EMA on a major exchange when merging proposal
+  - 269 USD/XMR at 1800 UTC 10/13/2021 w/ 14-day EMA on Kraken -> 92.6 XMR total
+
+If it takes me fewer than 240hrs, then I will allocate the extra hours toward whatever future Monero work I end up doing (or pass the left-over funds into the general fund if necessary).
+
+If I require more time, and the community supports it, then I may make another proposal to extend the hours.

+# What
+The goal is to create open-source software that aids people mining Monero with excess solar power in the most profitable way. It will accommodate for issues such as:
+
+- Time of day
+- Weather fluctuations
+- Avoiding depleting batteries below a threshold, that would damage them
+- Avoiding overheating the mining rig
+- Leaving enough power for your daily use
+
+# Intro
+I promised I'd help out in the [Monero Recruitment Matrix Room](https://matrix.to/#/#monero-recruitment:monero.social).
+Although there was just one direct request to me so far, recently I've also pro-actively proposed cooperation to the chat room members. I presented there 2 projects, that are on my mind, and don't require extensive crypto knowledge, typically not available to students. Yet the projects are still useful for Monero specifically. One of the projects that I have on mind is optimization of mining performance on a solar farm, depending on varying inputs. The member Endor ([endorxmr](https://github.com/endorxmr) on GitHub and endor00 on Matrix) signed up for being the main contributor to the project, while I would serve as a mentor: namely coordinator, reviewer and designer. Such a setup will guarantee, that I won't get dragged away too much from the maintenance of Monero, that I signed up for, while at the same time, Endor will be able to continuously have access to my years of experience in automatic control and object oriented design. Endor on the other hand is heavily involved in everything, that’s connected to mining profitability.
+
+Should Endor not make it until the deadline, I guarantee, that I will finalize the project by myself until the coming winter.
+
+Introducing the project: SolOptXMR – Solar Optimal mining of XMR.
+
+# Why
+The following [YT video](https://www.youtube.com/watch?v=7OpM_zKGE4o) is able to bring you more context why this idea has a chance for being a trending subject and is here to stay. The outline of this video is the following:
+Because of high initial, as well as perpetual investments required for producing power from solar collectors in Sahara/Nevada and delivering it to northern states, such an investment, contrived in the previous decade under the name "DESERTEC", turned out to be not the best possible investment. The project's relative profitability decreased across the years even more. The reason is, that the costs of production of solar panels dropped so low, that now it makes more sense to place them exactly where the produced power is most needed, even though the solar irradiation is lesser at these places.
+
+On a sentiment / geopolitical side of things, with the rising prices of heating gas, I expect many people will be wanting to save on their gas costs by switching to electrical heating. Since the majority of such heaters demand high power, ranging from 2kW to 2.5kW and since a given population will typically want to switch them on all at the same time, I predict that we'll be facing a decent wave of blackouts in the coming winter. This has motivated me to build my solar farm. 
+
+If you are an individual who likes to take the matters into your own hands, you might have considered building a small solar farm yourself. Although our system won't assume a given user's setup, my particular farm is configured as an isolated island. This means, that I don't sell my overproduction to the grid for the pennies, that the state offers, but rather use the production for mining and cooking, while the overproduction is temporarily stored in a pair of cheap but reliable car batteries. My farm serves as a perfect test bed for the system, that we're going to design and automate for you. Optimized mining of Monero on such a system amortizes the installation costs over the long run, will help you learn about electricity and motivate you to become more resilient. Further compatible extensions are possible, such as small wind generators as well as bikes with flywheels, that [recover kinetic energy](https://www.youtube.com/watch?v=MBW_2gUSMXc). Such systems are already available on the market, that tends to think ahead of the time, so you don’t have to DIY.
+
+# System description
+
+The dynamics of the system, that tries to optimize the mining efficiency has to take into account the following inputs and goals. Some of them are obvious while others maybe not so much.
+
+- Static astronomic data, that describe the relative movement of the Sun across the sky in various latitudes and times of year - yielding the maximal expected power that can be reached
+- Weather predictions - a cloudy sky can reduce the power output by more than 80%
+- If the predicted power generation is off the measured generation, a warning might be issued to clean the panels
+- Voltage (load state) of the batteries, as well as voltage that reaches the DC->AC transformer, as some of it might be lost in the cables, that are either too long or have accidentally formed an inductor
+- Predicted load state of the batteries on the next day before the Sun rises and the charging starts, as emptying the chemical batteries below 50% tends to damage them  
+- Mining rigs' temperature readouts as it's not worth to meltdown your hardware for those couple of Piconeros being mined.
+- A given computer's hashrate per Watt - use the most efficient ones first, but don't overheat them
+- A given computer's idle power cost - sometimes it will make sense to switch on certain less efficient computers only if there's really way too much power production, and/or the most efficient ones overheat, or it's predicted that they'd overheat soon under the, also predicted, future conditions.
+- Per core efficiency compared against multithreaded efficiency - for CPUs with smaller caches, the efficiency (in this case: hashrate) scales poorly with more threads working at the same time. In such cases it will make sense to spread the mining across longer periods of time on a single core.
+- The owners' power usage habits - taking into account, that you might want to use a low powered, compatible electric heating system at a given time of day, by leaving some energy in the batteries for you to consume, before the predicted event – learned either from your usage habits, or from your manually scheduled input.
+- The owners' setup – whether an isolated solar island is used, output connected to grid (for selling) or supplementing power losses from the grid (buying) or both of the last 2 options.
+
+The control mechanisms of the system would be the following:
+- Downclocking the CPUs - very easy to achieve under Linux with a high precision, thus allowing for a smooth control
+- Restarting the mining with a smaller number of cores
+- Putting computers to sleep and waking them up with Wake On LAN on the next day
+
+While it would be easy enough to control the system via PID controller, and I know a lot about it, such a system would have little prediction power, delivered only by the first differential part of the controller (the D) and only between the current and the previous state. Using a Time Series Analysis and Prediction tool, such as the already available `tsqsim`, will give the system the ability to look ahead into the future (like at least 48 hours ahead) and plan accordingly to maximize the gain per the unit of energy used, while at the same time planning carefully against overheat of the hardware, under-voltage of the DC->AC transformer, leading to an immediate halt of the system, as well as against under-voltage (as in: capacity) of the batteries, which would otherwise quickly damage them.
+
+The inputs to the system will come in a few forms – either assumed, input by the user or measured. The measurements can be easily supplied via smart plugs or measured directly. Ultimately it has to be left to the user to decide how much time to spend on providing additional inputs, that result in improvements of predictions, thus profitability. The goal here is however to keep the measurements optional, not to impose burden on the user.

I've been following the Monero project for over 5 years, learning the ins and outs of cryptocurrency mining and moderating the Supportxmr chat and the Monero Mining room on Matrix (#xmrmine:matrix.org). I am currently developing a comprehensive economic model of mining, and I plan to publish a small paper/series of articles over the next few weeks that will (hopefully) serve as "the ultimate guide to mining" for newcomers and professionals alike. A glimpse into my work can be seen in [this minimalistic script](https://gist.github.com/endorxmr/07364dc54f277abf487574d455d67341), that dynamically calcylates the CPUs mining profitability and compares it across various other CPUs. An example output (though shortened) can be seen below:

+# Milestones
+
+## 1 Initial setup
+The initial setup, that is able to use static astronomic data inputs (let’s call it by its name used in the industry: seasonality) and simple weather forecasts (sunny/cloudy/in-between) to make predictions based mostly on user input as to how much power a given computer and its cores consume, taking into account how much power is expected to be consumed in house for other purposes, that have to be treated as of a higher priority. Initially a status message will be displayed about what to do manually to maximize the selected goals. Plots of the inputs and outputs will be displayed, that explain why such a suggestion was presented.
+
+Will be done mostly by mj, since Endor shouldn’t be strained with too many foreign systems, only receive the system’s output signals. This will require about 2 weeks of work full time, that makes:
+- 6 (Monday-Saturday) * 2 (weeks) * 8 (hours) = 96 work hours
+- 96 work hours / 10h in a week = 9.6 weeks spread.
+
+## 2 Profitability calculator
+Profitability calculator, taking into account the power costs, grid’s buy-back prices (if available) and user’s price target, at which to sell the mined coins. Also a very important input will be the time-bound energy availability, delivered through the system from the Milestone 1
+
+This milestone will be done mostly by Endor, due to his experience in the field. I will only support via tips such as obtaining user input and code reviews, design suggestions, etc. I won’t count my pay on this one. This can be started before milestone 1) is finished, on a basis of simple generated sinusoidal signals, that will soon enough be replaced with real data.
+
+Endor’s:
+- 6 (Monday-Saturday) * 3 (weeks) * 8 (hours) = 144 work hours
+- 144 work hours / 15h in a week = 9.6 weeks spread.
+
+
+## 3 Measurements
+3) Support for various kinds of measurements – smart plugs, digital converters, software temperature readouts and even simple image recognition of LCD/LED displays of the DC→AC transformer and MPPT regulator.
+
+Both of us have experience in various parts here and wish to take equal part in this milestone. I’ll create up to two examples of image recognition.
+mj’s:
+- 6 (Monday-Saturday) * 2 (weeks) * 8 (hours) = 96 work hours
+- 96 work hours / 10h in a week = 9.6 weeks spread.
+
+Endor’s:
+- 6 (Monday-Saturday) * 3 (weeks) * 8 (hours) = 144 work hours
+- 144 work hours / 15h in a week = 9.6 weeks spread.
+
+## 4 Automation
+Automation of the system, including remote CPU downclocking, selecting the number of threads, putting computers to sleep, and waking them up via the Wake On LAN technology. We will be promoting privacy oriented and non-controversial software, namely: [p2pool](https://github.com/SChernykh/p2pool) and [xmrig](https://github.com/xmrig/xmrig), accordingly.
+
+Same as above, both of us have experience and ideas here. I already perform such tasks manually (via scripts) on my solar farm, so I know “the feel” of the system. Endor has many great ideas and a lot of expertise for this milestone as well, as this resonates with his prior experience with mining profitability and a variety of mining software + hardware.
+
+mj’s:
+- 6 (Monday-Saturday) * 2 (weeks) * 8 (hours) = 96 work hours
+- 96 work hours / 10h in a week = 9.6 weeks spread.
+
+Endor’s:
+- 6 (Monday-Saturday) * 3 (weeks) * 8 (hours) = 144 work hours
+- 144 work hours / 15h in a week = 9.6 weeks spread.
+
+# Legal & privacy
+The project shall be released under AGPLv3. It will send no telemetry by default, unless the user wishes to have their data uploaded and analyzed. The data will surely serve as a stabilization asset of the project and will be included in the automated system tests as one of many test cases. The complete data set to be sent will always be shown to the user for a review and approval.
+
+As I’m familiar with the EU laws regarding solar panels a bit, I will be providing the users non-legally-binding relevant advice.
+
+Even though I’m not strictly an electrical engineer, I know enough tricks in this field and I understand many nuances about the inner workings of such systems. I know what hardware are compatible with each other and how to calculate the supply and demand of the produced power. Therefore I can provide advice in this field as well, yet again: non-legally-binding.
+
+# Proposal
+As of 12 April, XMR/EUR is at 214.92 EUR.
+
+## mj:
+I will be able to spend about 10 hours / week on the project. An amount so low, that it doesn’t collide with my maintenance assignment, nor Monero Research Laboratory, once I switch there for a while. My rate per hour is 45 EUR. The total number of work hours is: 96 + 96 + 96 = 288. 
+288 [h] * 45 [EUR/h] / 214.92 [XMR/EUR] = 60.3 XMR
+
+## Endor:
+I will be able to spend about 15 hours / week on the project. My rate in my first ever proposal is at 25 EUR / h. The total number of work hours is: 144 + 144 + 144 = 432. 
+432 [h] * 25 [EUR] / 214.92 [XMR/EUR] = 50.25 XMR
+
+Since in this case we are really talking about seasonal data, that doesn’t require a lot of readjustments, further maintenance will not be a burden for any of us. Unless many new features are requested, we will gladly maintain it for you without asking for compensation.
+
+## Summary:
+60.3 + 50.25 = 110.55 XMR is what we're asking for. Thanks in advance!
+
+## Deadline calculation
+A rough deadline calculation based on the spread of the hours and including the tasks that can be done in parallel:
+9.6 [weeks] * 3 / 4.1 [weeks in a month] ~ 7 months.
+This coincides with the promise to finalize the project until winter if all goes well with Endor’s plan. If not, I can take over most of the responsibilities, as there are always ~1-1.5 month breaks between my maintenance proposals.
+
+Cheers!

+
+## What
+
+Result: A robust and modular wallet-rpc library, implemented in Rust with WebAssembly (WASM) as the primary target. This library aims to provide a flexible foundation for Monero wallet functionality. The deliverable for this proposal will be:
+
+1. the first part of the wallet-rpc library that can sync transactions and works reliably with remote nodes.
+2. A checkout flow built with this library. This is meant to be used, not just to demonstrate the features.
+3. Detailed documentation for the library, the relationship between nodes and wallets during the syncing process and a guide on how to use this to implement monero payment gateways.
+
+### Implementation
+
+list of initial tasks:
+
+- create function to turn address and private viewkey into viewpair
+- create function to scan transaction with sub functions
+- verify that there is no timelock present
+- calculate transaction amount
+- clarify responsibility of burning bug prevention for the caller
+
+- implement transaction fetching and storage
+- implement burning bug prevention in the checkout flow
+- write unit tests, document and publish the library
+- implement UI for the checkout flow
+
+this task list is not exhaustive and subject to change
+
+## Why
+
+As discussed as far back as two years ago: https://github.com/seraphis-migration/strategy/issues/2
+The wallet2 Monero library is a 15k lines CPP file. The official monero repo does not contain a deliverable that is easily linkable from other programs. Every project that is a wallet or contains wallet-like functionality (payment processors, hardware wallets, point of sale terminals) needs to implement its own wrapper to expose a C ABI.
+
+This results in collectively wasted hours and headaches. It increases supply chain risk and makes building things with Monero harder. As a result, projects get more expensive, take longer or don't happen at all.
+
+This library aims to counteract the issues and limitations of wallet2.cpp by directly targeting wasm.
+Using wasm as the main target means that this library is forced to be implemented in a way that meets the expectations outlined here: https://github.com/seraphis-migration/strategy/issues/1
+
+The benefits of this approach:
+
+### 1. It will be easily linkable
+
+WASM is a very constrained target. There is no garbage collection and multi threading. Getting code to run there means having to write it in a way that is easy to interact with from any language and in any environment.
+
+### 2. It will be more robust
+
+The current monero wallet-rpc is at times unresponsive, because its concurrency mixes the responses of the local rpc with the network interacting with the node. More details in the [monero-playground repository](https://github.com/spirobel/monero-playground). The WASM target constraints ensure that this library decouples the concurrency and networking from the wallet code. The result will be more robust.
+
+### 3. It will be more flexible and not tied to any platform / target
+
+Wallet code deals with the most sensitive data. It should not have unnecessary dependencies or bloat. To give a practical example: monero currently vendors a 4000 lines of code [logging library](https://github.com/monero-project/monero/blob/master/external/easylogging%2B%2B/easylogging%2B%2B.cc) that introduces a dependency on signals. The WASM target constraint means that things like that can't and wont be introduced into this library.
+
+## Milestones and Timeline
+
+value commitment:
+
+The 3 deliverables outlined in the **What** section are the promised outcome of this proposal. Any time left over from the time commitment will be used to further advance the road map. The value commitment is due for the milestone of the second month.
+
+time commitment:
+
+- 100 hours per month for two months (100 hours total)
+- Compensation: 50 XMR per month (100 XMR total)
+- Total compensation: 100 XMR
+
+## Future Roadmap
+
+The next step on the road map is to add transaction building and signing functionality to the library and migrate [the browser wallet](https://www.youtube.com/watch?v=4DLcsQ45zoE) to it.
+
+My endgame is to **remove all friction from the privacy enabled web shopping experience**. Currently most **Monero shoppers** have to copy and paste addresses from the tor browser into their wallets. This opens the door to unnecessary opsec failures, as it is easy to get confused and intimidated by long strings of random numbers.
+
+**A core part of staying private and safe online is to compartmentalize identities.** Qubes OS made some advancements in improving the UX of this activity by coloring different windows that are tied to different identities in a unique way.
+
+The reality is, that installing a different operating system is a large ask for the average person. At the same time we need to onboard as many people as possible to these habits, so we can operate safely in the crowd.
+
+The other venue of attack is **using the browser for compartimentalization.** And before anybody complains: no this does not involve untrusted javascript frontend code.
+
+There is a big difference between a browser wallet and web wallet. A web wallet is a flawed experiment that is borderline custodial, as it runs wallet code inside the context of a website. This is not to be confused with a browser wallet.
+**A browser wallet runs trusted code as a compartmentalized, constrained program inside of a sandbox.**
+
+There is a massive opportunity here to reduce friction by making it easy to separate online identities. The TOR browser currently enables the use of one separate TOR circuit for each tab. **Imagine we have one monero address per tab that is used for login and to send and receive payments.** It makes it much harder to mess up.
+
+One last concern that comes up is that there might be zero day exploits in the browser, as it exposes a potentially larger attack surface. This can be mitigated by making the wallet a multisignature wallet and **using a second device like an android phone or a monero seedsigner to authorize every transaction.**
+This means two devices need to be compromised to capture funds, which is unlikely.

+
+# Who
+
+I am [SyntheticBird](https://github.com/SyntheticBird45), Cuprate contributor.
+
+# What
+
+Cuprate is currently in alpha version and a lot of features are planned on the roadmap up to beta phase. One of the features present on this roadmap, and that was [originally presented when announcing Cuprate](https://github.com/Cuprate/cuprate/blob/fc9b077d946fe8b7746c45ae8b299a87b2014cbf/readme.md?plain=1#L57), is native support for Tor network. This CCS proposal intend to fulfill this milestone.
+
+I will work for an estimated 2 months, from April to end of May, on Cuprate with the goal of implementing native Tor support into `cuprated` through the `arti-client` crate and other miscellaneous improvements.
+At the end of this CCS, testers will be able to:
+- Bootstrap Tor network within Cuprate or use Tor system daemon.
+- Use Tor for outbound clearnet connections.
+- Natively connect to onion monero nodes.
+- Generate an onion service for accepting inbound Tor connections.
+
+# Tasks
+
+The planned set of tasks to complete can be found at this Github gist: https://gist.github.com/SyntheticBird45/4c554d3c1e7ae6f8d237d7dd49c2d2f0
+
+It is subject to change but overall the required work can be separated into 3 categories:
+
+### 1. Alternative network integration into P2P components.
+
+Currently, Some P2P components have limited support for alternative network rules. This will require modifying `AddressBook`, `Connector`, `HandshakeBuilder`, `cuprate-dandelion` crate and `cuprated`'s dandelion implementation, and others to be *anonymization-network-aware*. After this work, we will define a new `NetworkZone` called `Tor` to connect to onion monero nodes.
+
+### 2. Implementation of Arti and Tor Daemon support
+
+Implementing `arti-client` inside `cuprated` and `cuprate-p2p{-*}`. Configurations, initialization, bootstrapping and launching onion services if requested. System tor daemon will also be supported.
+
+### 3. Documentation
+
+Update [Architectural book](https://architecture.cuprate.org) and [User book](https://user.cuprate.org/)
+
+# Additional work
+
+In the event that all guaranteed items are completed before the 2 months, I will spend my remaining time assisting (Issues, PRs and Reviews) on whatever is agreed is highest priority, or working on the following items:
+
+- Custom Allocator support (Performance improvements for Musl based linux distributions and potentially minor improvements on other OSs)
+- SOCKS5 proxy support for p2p
+- Fjall database integration
+- Related documentation
+
+# Milestones
+
+### 1. First month
+
+26 XMR
+
+### 2. Second Month and completion of main tasks
+
+26.5 XMR
+
+# Licensing
+
+All the works completed under this CCS will be delivered to the [`Cuprate/cuprate.git`](https://github.com/Cuprate/cuprate) github repository. This work will follow the current repository licensing:
+- All work inside `/binaries` is licensed under `AGPL-3.0-only`.
+- The rest of the root and crates are licensed under `MIT`.
+
+For more information about the Cuprate github organization, please [visit the organization page](https://github.com/Cuprate)
+
+# Funding
+
+I will be working 30 hours per week during 8 weeks at 45\$/hr - 205\$/XMR.
+30×8=240 | 240×45=10800 | 10800÷205=52.5

+## Proposal deprecation / Repurposing of funds (21st Dec, 2024)
+
+AlexAnarcho and hundehausen shared a [candid update](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/524#note_27732) regarding progress of TipXMR. Exerpt below:
+
+>We were young and naive and thought "how hard can it be to code this up" - harder than we thought it turned out.         
+>
+>We had very high standards, trying to use WASM wallets on the client-side where no info is leaked to the hoster of the TipXMR service, but this lead to a high barrier - which in turn lead to us never shipping anything   
+>
+>[...]    
+>
+>We are okay to deprecate the TipXMR CCS proposal and pass our collected funds on to this XMRChat proposal.
+
+The remaining funds from:
+
+* Milestone 2 - Working Prototype with implemented WASM wallet and front-end mockups (34.56XMR)
+* Milestone 3 - Finished product and launch of serivce (36XMR)
+
+Will be rewarded to https://xmrchat.com/ - [source](https://github.com/sa8ab/xmrchat)

+I want to start off the year by clearing out a good chunk of the small-to-medium size issue/feature backlog for Feather. At the same time, making sure [pending build system PRs](https://github.com/monero-project/monero/issues/9631) for Monero core get reviewed and merged, particularly everything we need for FCMP++. 
+
+After that, I want to continue efforts to add multisig support to Feather by evaluating kaya's FROST-inspired multisig implementation as a more robust replacement for wallet2's implementation. A related [audit](https://ccs.getmonero.org/proposals/monero-serai-wallet-audit.html) is expected to conclude in March.

+
+### What
+
+This CCS proposal is for 3 months of full time Feather Wallet development.
+
+The goal for this proposal is to get Feather out of Beta and release the 1.0 version.
+
+### Background
+
+See the previous [CCS proposal](https://ccs.getmonero.org/proposals/tobtoht_feather_dev_q1_2021.html).
+
+### What I want to work on
+
+To ensure the first major release is as stable, robust, and reliable as possible I will be mainly focussing my efforts on polishing the existing feature set (and extending it where needed).
+
+- Fix bugs and issues as they arrise
+- Further improve the UI/UX (layout, actionable error messages, etc)
+- Improve documentation and user guides
+- Add more compile flags for minimal/alternative builds: (no-Tor, no-Websocket, etc)
+- Refactor parts of the codebase
+- Allow compiling on more architectures
+- Extensive QA testing on all supported platforms
+- Commission a redesigned logo
+- Upstream changes to libwalletqt / wallet_api
+- Improve the setup procedure (Windows installer, Debian package on PPA, mac DMG)
+- More advanced coin control: manual input selection and individual output labeling
+- Extend hardware wallet support to include Trezor devices
+- Allow opening multiple wallets at once
+
+Once the is more clarity surrounding Triptych-compatible multisig (see [1](https://repo.getmonero.org/monero-project/ccs-proposals/-/blob/master/cypherstack-sarang-triptych-research.md), [2](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/225#note_10903)) I will continue working on integrating multisig into Feather.
+
+As always I will rely heavily on user feedback to determine where to put my focus.
+
+### Who
+
+Hi, I'm tobtoht. Creator of xmrguide and maintainer of Feather Wallet.
+I have been an active contributor to the Monero ecosystem since April 2018.
+
+Some of the things I have worked on are:
+
+- Created and maintained guides to set up Monero on Tails and Whonix ([xmrguide](http://xmrguide42y34onq.onion/), [reddit](https://old.reddit.com/r/Monero/comments/h8pbc2/))
+- Made miscellaneous contributors to the GUI (most notably Tails support)
+- Maintained a [list](http://xmrguide42y34onq.onion/remote_nodes) of .onion remote nodes with their status
+- Co-created Feather Wallet with dsc
+
+### Proposal
+
+40 hours per week at 45 USD/hour for 3 months (mid May to mid August) for a total of 91.5 XMR. At a rate of $236/XMR.
+
+Progress will be reported in #feather on OFTC. Monthly updates will be posted to /r/FeatherWallet in the form on release changelogs.
+
+Feedback and comments are welcome.
+
+**To donators**: In the week since I made this proposal there has been some very significant volatility, making it difficult to establish a "fair" XMR/USD price. As such I had to adjust the quoted price down several times because the difference had grown larger than my risk tolerance. I have currently settled on ${current_price} + 20%, in the expectation that the price will recover a bit after such a steep decline.
+
+To ensure I can sustain myself in the coming months AND the community gets its money's worth, I will extend the time spent on this proposal in case there is significant price appreciation over the next three months, like I did with my previous CCS (1.5 months overtime).

+
+### What
+
+This CCS proposal is for 3 months of full time Feather Wallet development.
+
+Non-exhaustive list of things I want to work on/towards or experiment with:
+
+- Bootstrappable builds
+  - Leverage [Guix](https://github.com/bitcoin/bitcoin/tree/master/contrib/guix) to produce cross-compiled, reproducible, [bootstrappable](https://bootstrappable.org/) builds for all target platforms and operating systems. Most of the work for this is already [done](https://github.com/feather-wallet/feather/pull/20). This has the added benefit of greatly speeding up release engineering, allowing for quicker release cycles.
+
+- Offline transaction signing using animated QR codes
+  - Export/import outputs, key images and transactions using animated QR Codes based on Blockchain Common's [Uniform Resources](https://github.com/BlockchainCommons/bc-ur).
+  - Work with the [Keystone](https://keyst.one/) team to add support for Monero and integrate with Feather.
+
+- Multi-node syncing (experiment)
+  - Syncing a month worth of blocks now requires more than 300 MB of data. Wallet synchronization (when connected to a remote node) is often limited by one of two things: your download speed or a node's upload speed (for mobile devices your CPU might play a role too). Multi-node syncing will experimentally determine the fastest nodes from your node list and automatically gather blocks from the highest performing nodes to utilize as much of your available bandwidth as possible. If you are on a fast internet connection this can result in dramatically faster syncing.
+
+- Allow skipping synchronization
+  - POV: You just opened your wallet on Tails after leaving it unopened for 3 months. You proceed to wait an hour or more for your wallet to synchronize knowing that there has been no activity. An advanced option to skip synchronization will eliminate the wait and allow you to send transactions almost immediately.
+
+- Improve Tor support and add support for more anonymity networks
+  - Add support for Tor bridges and stream isolation
+  - Switch the Tor client implementation to [Arti](https://blog.torproject.org/announcing-arti/) (when it is ready)
+  - Remove the hard dependency on Tor and allow Feather to be used without anonymity networks
+  - Modularize the anonymity network code to make it possible to integrate other networks like I2P and [Nym](https://github.com/nymtech/nym).
+
+- Mining interface overhaul (+ P2Pool support)
+  - The Mining tab is a bit crude. Mining is [not trivial](https://docs.featherwallet.org/guides/mining-setup) to set-up for new users, and it lacks configurability for advanced users. It's currently not possible to mine without having a wallet open. I want to move the Mining tab to a utility that can be accessed via the taskbar icon. Users should be able to quickly setup P2Pool, solo and pool mining. Feather will be able to run in the background and allow users configure scheduled mining, as well as provide a dashboard where users can check their mining stats and make changes to the configuration.
+
+- Improve packaging for Linux distributions
+  - Make Feather available as a Flatpak, Debian package, and maintain a working -bin package on the AUR. I also want to work on documentation that will help maintainers package Feather for their distribution.
+
+- Support more ways of spending Monero
+  - The libwallet interface lacks support for various advanced ways of spending Monero. The current Feather release added manual input selection. More is still desired, such as multi-destination sweeps or spends with an alternative change address.
+
+- Improved documenatation
+  - I'm already quite happy with the [documentation](https://docs.featherwallet.org/) in it's current state, but there is still room for improvement. A search feature is lacking and some parts could be improved with screenshots. Other parts can be rewritten to improve clarity and a glossary would be a welcome addition. I also want to add a section that goes in depth about threat-modeling to help users make more informed decisions about how they should use and configure the program to address their specific privacy or security concerns.
+
+- Fix bugs and issues as they arise
+
+I'll also work on reviewing contributions to CLI / GUI where I can and work on upstreaming patches to core.
+
+As always I will heavily prioritize user feedback when deciding what to focus on.

+
+### What
+
+This CCS proposal is for 3 months of full time Feather Wallet development.
+
+The goal of this proposal is to:
+
+- Reach feature-parity with the GUI (this mostly concerns hardware wallet support)
+- Further advance the Monero desktop wallet space by implementing new (and experimental) features.
+
+### Background
+
+- Feather was [announced](https://old.reddit.com/r/Monero/comments/idujx0/feather_free_opensource_monero_desktop_wallet/) on Aug 21 2020. 
+- A CCS [proposal](https://ccs.getmonero.org/proposals/feather-2020.html) funding the initial stages of development was accepted on September 1. 
+- The first alpha builds became [available](https://old.reddit.com/r/Monero/comments/j8kn8e/feather_a_brand_new_monero_gui_desktop_wallet/) on Oct 10. 
+- During the alpha time was spent on:
+    - Troubleshooting teething problems
+    - Bugfixes and performance improvements
+    - Getting the websites and build infrastructure up and running
+- The first beta builds were [announced](https://old.reddit.com/r/FeatherWallet/comments/kdmj3b/feather_beta2_released/) on Dec 15.
+    - The beta introduced signed release binaries.
+    - The focus for the beta was to fix the remaining UI/UX issues before adding new features. This is now mostly complete.
+    - A total of 211 pull requests (171 made by me) were submitted to the repository since the alpha release.
+- Some features that were added between the previous CCS proposal and now are: Windows support, view-only wallets, offline transaction signing, advanced transaction overview ([image](https://featherwallet.org/theme/img/feather_send_advanced.png)), transaction rebroadcasting, XMRig integration and reproducible Linux builds. Reproducible builds are mostly thanks to work done by Xiphon on the GUI.
+
+### What I want to work on
+
+- Hardware wallet support (most requested feature, so this is definitely happening now)
+- More exchange integrations (among which LocalMonero)
+- More advanced coin control features: manual input selection and individual output labeling
+- An in-wallet troubleshooting wizard that detects and suggests fixes for common issues ([example](https://git.wownero.com/feather/feather/issues/144))
+- Easy to use 2/2, 2/3 multisig (work on the message transportation layer and UI/UX design can commence before it is clear what changes Triptych/Arcturus will bring to multisig)
+- Qr scanner (scan addresses with laptop camera/webcam)
+- Multi destination transactions
+- Debian package
+- Sync over clearnet, construct & broadcast transactions over Tor
+- Approach the Tails team to discuss potential inclusion of Feather Wallet by default
+- Further UI/UX improvements (including more actionable error messages, better UI feedback)
+- Upstreaming of changes to libwalletqt / wallet_api
+- (Separate from Feather): Monero Daemon as a system service ([more info](https://git.wownero.com/feather/feather-meta/issues/3))
+
+This is a non-exhaustive list of some of the things I want to work on during the proposal.
+I expect the majority of the items on this list to be completed at the end of the 3-month period (with the exception of multisig, which will likely take longer).
+As always I will rely heavily on user feedback to determine where to put my focus.
+
+### Why contribute to Feather development?

+- It is an excellent testing grounds for features that may later be implemented in the official GUI (14 word seeds, coin control, multisig, etc)
+- There is more room to experiment with UI/UX and features and see what works before committing to it in a reference wallet.
+- Some users cite its simplicity, focus on user experience, quick setup, addition of power user features and similarity to Electrum as reasons they prefer it over the GUI
+- Feather will remain open source and licensed under BSD-3.

+### Proposal
+
+40 hours per week at 45 USD/hour for a total of 150 XMR. The XMR/USD rate is based on current exchange rate of $144 XMR/USD.
+
+This will cover January/February/March. Any hours left over will bleed into April.
+
+Progress will be reported in #feather on OFTC. Bi-monthly updates will be posted to /r/FeatherWallet in the form on release changelogs.
