Monero Observer: time for a second break in 4 years

Sun, 23 Nov 2025 UTC

It’s been a long road: 4+ years of Monero Observer since 2021 with a single break in 2023¹. It’s time for me to take some time off after ~780 consecutive days of work.

My previous statement also applies to this period:

In an effort to mitigate long-term exhaustion and get back into physical and mental shape, I’m opting for a total disconnect: no reporting, no communications.

Subscribe to the RSS² to be notified of my return.

It is likely that I will implement some changes to the project: migrate away from Jekyll’s awfully long local build times, redesign the website and potentially expand the overall journalistic approach.

Thanks for reading and supporting my work, anon.

Onward.

jeffro256 submits CCS proposal for Carrot/FCMP++ dev work in Q4 2025

Sat, 15 Nov 2025 UTC

jeffro256¹ has submitted a new CCS proposal² looking to continue working full-time on Carrot³ development - Monero’s main addressing protocol post-FCMP++ - for 3 months (Q4 2025):

The last quarter we launched the FCMP++ Alpha Stressnet. It has generally been a huge success, showing that the node can handle a reasonable level of FCMP++ stress while still revealing a large swath of improvements to make. [..] In the following quarter, I want to continue on this journey.

Total funding proposed: 96 XMR.

ETA: ~3 months.

Proposed work overview

Support new unbiased hash-to-point in the Carrot code
Make some misc code changes to Carrot code to better match the spec
Research/review/reach consensus/implement scaling changes
Begin soliciting Carrot core implementation audits
Help launch FCMP++ Beta Stressnet with consensus / addressing protcol changes
Solicit help for multisig implementations of Carrot
Help out with the FCMP++ integration

jeffro256 has contributed 125 merged commits⁴ to the Monero core repository, worked on the Seraphis migration project in 2023/2024⁵, and also wrote up the Carrot specification³ for formal auditing⁶ and implementation⁷.

It is worth noting that the dev has recently completed the final milestone for their previous CCS proposal⁸.

To read, share your feedback, ask questions and support this proposal, consult !625².

This is an ongoing story and the report will be updated when new information is available.

Update: moved to funding stage⁹.

jeffro256 completes 2025 Q3 Monero dev work CCS

Tue, 11 Nov 2025 UTC

jeffro256¹ has posted a third and final progress report² for their full-time 2025/Q3 Monero (Carrot³) development work CCS proposal⁴:

Since the last milestone update, I have spent a lot of time upstreaming Carrot/FCMP++ code and general fixes. The biggest single changeset I worked on was the mempool input verification cache⁵. This has had positive impacts on block propagation and reorg times in the stressnet. I have also been reviewing a lot of Berman’s fixes for the FCMP++ stressnet. I did a couple of bug fixes myself after a lot of time spent debugging live nodes. I am currently working a lot to improve foundation for HW device support for the Carrot integration.

Work overview

* WiP branches: carrot_core, carrot_impl, fcmp++-stage, fcmp++-stage-cold-hot
* Merged PRs:
  * [core #10156] cryptonote_core: rm confusing/redundant BP consensus rule
  * [core #10166] BlockchainDB: rm skip_coinbase in get_blocks_from()
  * [core #10170] epee: align container pod as blob serialization 
  * [carrot/FCMP++ #193] blockchain_prune: add FCMP tables and check DB version
  * [carrot/FCMP++ #196] blockchain_prune: add FCMP tables and check DB version [STRESSNET]

[ANN] Why Monero - Agorism

Fri, 07 Nov 2025 UTC

Without privacy, agorism is just a nice idea. But with privacy, agorism becomes action. Monero allows us to transact freely, build underground economies, and support one another without the interference of the state.

rehrar submits CCS proposal to fund Monero community assembly at C9C3

Thu, 06 Nov 2025 UTC

rehrar¹ has submitted a CCS proposal² - on behalf of the Critical Decentralisation Cluster (CDC)³ - looking to partly fund the Monero community assembly at the forthcoming 39th Chaos Communication Congress (39C3)⁴:

We’re looking to raise 200 XMR so we can improve the things that were good last year, and double down on the things that went well. We want to have Monero specific workshops (setting up nodes, wallets, going over some of the cryptography, etc) and continue the trend of having Monero folks run a coffee booth among other things. [..] A more complete budget will follow soon. The asked 200 XMR does not cover all expenses, but, again, additional sponsors are already on board, so the expected risk of not being able to deliver if this CCS is funded is essentially zero.

Total funding: 200 XMR.

ETA: TBD.

Milestones

M1: Half up front (100 XMR)
M2: Half after (100 XMR)

It is worth noting that the C3 annual four-day conference is scheduled to take place on 27–30 December 2025 in Hamburg.

To read the full proposal, share your feedback, ask questions and support this CCS, consult !622².

This is an ongoing story and the report will be updated when new information is available.

P2Pool v4.12 released with full Tor support

Thu, 06 Nov 2025 UTC

SChernykh¹ has released P2Pool² version 4.12³ with full support for Tor⁴, various improvements and bugfixes:

Changes overview

* [Feat] TOR is fully supported now
* [Feat] Wallet address: added checks for FCMP++ compatibility
* [Improvement] Speed up crypto derivations with vartime ops (faster sync times)
* [Improvement] De-duplicate tx hashes and pub keys (saves memory, off by default)
* [Fix] Fixed a crash at startup on Windows when using some DNS servers

The full list of changes since v4.11 is available on Github⁵.

Before using the software, you should verify the SHA256 sums with SChernykh’s GPG key⁶.

The README⁷ has valuable information about features, defaults, how pool shares work, build instructions and a short mining guide. If you need assistance, read the FAQ⁸ and join the project’s IRC channels⁹.

Note that it is strongly recommended to synchronize your system clock before you start mining; create a new wallet and don’t use it for anything else but mining for privacy reasons - all wallet addresses are public on P2Pool!

hbs posts progress report for EVM-XMR atomic swaps CCS

Sat, 01 Nov 2025 UTC

hbs¹ has posted a progress report² for their CCS³ proposal to continue working on EVM-Monero atomic swaps⁴:

The code has been made available on Codeberg⁵ under the permissive MIT license as advertised in the CCS proposal. The GUI has reached a point where it can be used to view, create and manage atomic swaps. A current version is deployed on IPFS and available at beta.moneroswap.eth.link. [..] The project has reached the stage where testing by users to collect feedback on the overall user experience is what is now needed. I intend to advertise “swappy sundays” on the Matrix room to encourage people to perform test swaps and report their feedback.

The complete update is available on GitLab².

Join #moneroswap on Matrix⁶ to get involved with the project. Consult the previous Monero Observer report⁷ to learn more about this story.

sukunetsiz creates Monero wallet RPC web UI 'Cuzdan'

Sat, 01 Nov 2025 UTC

sukunetsiz¹ has announced² the release of Cuzdan³ - a Flask/Python-based web interface for managing Monero RPC wallets:

I’m sukunetsiz, developer of Kabus and Kabus-X Monero marketplace scripts⁴. I’d like to introduce a new side project of mine called “Cuzdan,” which you can also use with your Kabus installations. [..] a web interface for your Monero wallet RPC that allows you to view all transactions, send Monero, and easily receive payments from your running wallet.

Features overview

* Multi-Address Management
* Balance Display & Transaction History
* Built-in transaction sending with balance validation
* Automatic QR code for the latest subaddress for easy receiving
* Fully Local: No external dependencies - everything runs locally

The complete list of features, screenshots, quick start and config instructions are available in the project’s repository on GitHub⁵.

Consult the previous Monero Observer report⁶ to learn more about this story.

Note: the project is still under active development - review the code before using; this is not a standalone “wallet” like Feather Wallet or Cake Wallet. Cuzdan is designed to help web developers who use Monero for payments by providing an easy way to manage their RPC wallets.

[ANN] MyMonero Is Closing Its Doors — Here's How to Migrate Safely

Fri, 31 Oct 2025 UTC

MyMonero has announced it will sunset on January 6, 2026, and users will need to move their funds before that date.

Edge already provides the fast-sync experience MyMonero users know and love, offering a smooth and private way to continue managing XMR securely. With in-app swaps for 130+ assets with no KYC, full self-custody, and key import coming soon, Edge is proud to continue supporting the Monero community and its ongoing commitment to financial privacy.

redsh4de submits CCS proposal to implement Getmonero.org redesign

Tue, 28 Oct 2025 UTC

redsh4de¹ has submitted their first CCS proposal² looking to implement rehrar³’s Getmonero.org website redesign concept⁴ from last year⁵:

This proposal delivers a full technical foundation of the redesign for getmonero.org, including UI components and the blog with complete migration of historical blog posts. It does not change or migrate any other non-historical content (e.g., page content, Moneropedia, Guides, Dev docs), as there doesn’t seem to be consensus on that yet. [..] I already have a working prototype of the website that I developed as volunteer work and open-sourced, which you can preview and explore

Proposed funding: 48 XMR (USD 35/hr).

ETA: ~13 weeks.

Milestones

M1: Technical foundation, UI components, and blog system (29 XMR)
M2: Accessibility, CI/CD, and final updates & optimizations (18 XMR)

redsh4de’s working prototype built with Astro⁶ is available on GitHub/Vercel⁷.

To share your feedback, ask questions and support this proposal, consult !620².

This is an ongoing story and the report will be updated when new information is available.

Update: moved to funding stage⁸.

Mon, 27 Oct 2025 UTC

felipebrunet¹ has announced² the release of a new XMR-only non custodian point of sale app (v1.0.4)³ for Android⁴ that enables multi device and prevents address reuse:

Just came here to inform about a new monero point of sale. Just needs a node to connect to. Open Source. Still has a few minor UX bugs, but I am working on them. [..] User needs a Monero Node (ideally his/her own), a Monero Base Address and a Monero Secret View Key. The Monero Base Address and Secret View Key will NEVER leave the device. 100% privacy preserved. Application only connects to the Monero Node the user defines.

Parameters overview

* Server (Monero Node)
* Monero Base Address
* Monero Secret View Key
* Major Index (Monero account)
* Maximum Minor Index (will move from 1 to this number and start over)
* Shop or Restaurant name
* Tips/No Tips
* FIAT currency to charge

The xmr_pos app is also available as a signed APK on GitHub⁵.

Note: this is a new project; inspect the code before usage.

MAGIC Grants to release 'Monero first' Skylight Wallet

Sat, 25 Oct 2025 UTC

MAGIC Grants¹ is getting ready to release Skylight Wallet², a new self-custody Monero first light-wallet:

If anyone wants to beta test a new Monero light-wallet that connects to the LWS you specify, please let me know! I’ll need your Google Play email to invite you to the testing group. Google Play only for the moment, not iOS. I’ll announce it more widely in the coming days (e.g. Reddit). I’m very excited about this! (sgp/Justin Ehrenhofer³)

Skylight Wallet is freshly made but it also uses libraries from Cake Wallet⁴, vtnerd⁵, and Cypher Stack⁶.

Note: the code will be published on GitHub in Magic Grant’s ‘skylight-wallet’ repository⁸.

[ANN] getmonero.org Should Move Beyond Cloudflare

Sat, 25 Oct 2025 UTC

Monero exists to protect financial privacy in a world that systematically destroys it. Monero keeps finances confidential and secure. It is an act of resistance against surveillance. Yet the project’s official website getmonero.org sits behind Cloudflare, a corporate MITM layer that inspects, filters, and proxies encrypted connections.

atsamd21 releases Haveno Android app v0.4.11.0

Wed, 22 Oct 2025 UTC

atsamd21¹ has released Haveno Android app² version 0.4.11.0³ with various fixes, updates and improvements:

This is the mobile version of Haveno, it uses the gRPC daemon from Haveno but is not endorsed by the Haveno developers. The app currently only works on Android, however, MAUI also supports iOS so with some work it could support both with the limitation that iOS requires a remote Haveno node.

Changes overview

Update instructions for network operators
Round amounts for taker when offer has a range
Show taker deposit amount on offer and always show no deposit offers
Show distance from market price when offer uses fixed price
Fix modal not closing

Consult the previous Monero Observer report⁴ to learn more about this story.

To support further development of the app transfer any amount of XMR to the project’s donation address⁵.

Note: the project is a WiP; the repository is configured for the public test network/stagenet.

[ANN] Why centralised KYC exchanges allow ZEC. Clarification on the current state of ZEC Trusted Setup in their production blockchain.

Sun, 12 Oct 2025 UTC

That’s why ZEC can be easily listed on virtually all KYC centralised exchanges: a dedicated group of people can trace all the hidden transactions because there exists a key that has not been properly wiped out.

MyMonero to shut down on January 6 2026, picks Cake Wallet as 'ideal successor'

Tue, 07 Oct 2025 UTC

fluffypony¹ has announced plans² to shut down MyMonero³’s wallet service on January 6 2026 - after almost 12 years of operation - and hand the reins to Cake Wallet⁴ in a move away from XMR lightweight wallets and toward more decentralized solutions:

After over a decade of serving the Monero ecosystem, MyMonero has decided to sunset its wallet service on Tuesday, January 06, 2026. We’ve worked closely with the Cake Wallet team to help provide continuity for our users, given their strong track record in the Monero community. [..] Light wallets requiring view keys are increasingly at odds with Monero’s privacy evolution. We’d rather sunset gracefully and hand the reins to a fantastic successor than compromise on privacy.

Timeline

Jan 6 2026: MyMonero service completely offline
Feb 6 2026: All MyMonero data permanently destroyed

Users are advised to export their 25-word Monero seed phrases from MyMonero or transfer any XMR to Cake Wallet before the deadline.

For migration support, contact the MyMonero and/or Cake Wallet teams via email⁵.

This is an ongoing story and the report will be updated when new information is available.

Update: add link to Cake blog post for reference⁶.

Fri, 26 Sep 2025 UTC

With Bridgeless and Confidential Layer, swaps are non-custodial, decentralized, and fully private — hiding senders, recipients, and amounts.

tevador proposes 'Share or Perish' selfish mining mitigation

Thu, 25 Sep 2025 UTC

RandomX¹ author tevador² has published a new soft-forking proposal to mitigate selfish mining³ - Share or Perish (SoP)⁴ - that could potentially be much more resilient to long reorgs:

For deeper reorgs of 10+ blocks, the attacker would need to mine on average 80 work objects faster than the honest chain. [..] the attacker would have a 50% chance of success after 5-6 years of selfish mining. With Nakamoto consensus, the attacker can expect to achieve several 10-block reorgs per day.

SoP doesn’t affect rewards or other consensus rules and is partly based on tevador’s previous Publish or Perish (PoP)⁵ proposal combined with the idea of workshares⁶.

Consult the previous Monero Observer report⁷ to learn more about the ongoing attack against Monero.

This is an ongoing story and the report will be updated when new information is available.

Update 25/9/26: actual average time between 10+ block reorgs is not 5-6 years, but only about 65 days according to preliminary Monte Carlo simulations⁸.

Update 25/9/29: 10+ reorg avg. time bumped to ~3 years after new SoP changes⁹.

ki9 creates 'karmine' script to counter selfish mining threat

Mon, 22 Sep 2025 UTC

Keith Irwin (ki9¹) has created karmine² - a bash script that can be used to run XMRig³ whenever selfish mining⁴ activity is detected, in an attempt to prevent future Monero network reorgs⁵:

It’s a bash script to call a hook when selfish mining is detected. The main purpose is to activate miners when the network needs the extra hashrate. [..] When qubic is mining selfishly, the network needs your help! Additional hashpower means it’s less likely that they are able to perform a reorg on the network. So you can use karmine to run xmrig when your hashpower is going to do the most good for the network.

The script uses DataHoarder’s tips.txt⁶ page to find indications of selfish mining. Installation and usage instructions are available in the project’s Gitea repository⁷.

Note: always inspect the code before running any scripts.

This is an ongoing story and the report will be updated when new information is available.

Update: removed reference to the currently unmaintained xmrprice.fyi project.

Monero Konferenco 2026 cancelled: 'this is not the end of Monerokon'

Sun, 21 Sep 2025 UTC

ceetee¹ has announced in a short planning meeting yesterday² that the MoneroKon staff team has decided to not move forward with the Monero Konferenco 2026 Prague event³ due to legal issues and unreliable payment providers:

Ultimately we believe that MK26 is unlikely to succeed given the current circumstances. [..] the staff team, have decided to not move forward with MK26 in prague. This was not a decision we made lightly. [..] we want to take a break to recover, so we can resume with MK27 and actually enjoy the process.

According to the post, any remaining funds and inventory will be allocated to future MK events depending on community consensus. Current contracts will be maintained and are expected to be used for MK27.

The complete announcement is available on Monero Observer⁴.

This is an ongoing story and the report will be updated when new information is available.

DataHoarder publishes timeline of historical Monero 18-block reorg from September 14 2025

Wed, 17 Sep 2025 UTC

Monero contributor DataHoarder¹ has published a full archive² of 115 invalidated mined transactions³ and all orphaned (and non-orphaned) blocks⁴ that apparently resulted from the historical September 14 2025 Monero 18-block reorg⁵:

On September 14th 2025, from 05:10 to 06:20 UTC, Qubic mined an alternate chain from height 3499659 to 3499678, for a total of 20 blocks. This alternate chain attempted and succeeded in orphaning the then canonical chain from height 3499659 to 3499676, for a total of 18 blocks. [..] There is an ongoing marketing and disinformation campaign by Qubic, downplaying the damage done or straight out claiming the transactions never existed in the first place, or that the reorg never happened! This is pure madness, insanity, and malevolence.

Log entries summary

[Time] [Notes]
12  Attacker mines first selfish alternate block
33  Attacking chain reaches enough depth to cause a 10 block reorg
49  Monero reaches 10 block height since attacking chain split
53  10 invalidated transactions
01  28 invalidated transactions
03  Attacker witnesses existence of orphan chain by mining Tari
15  Attacker mines their last block before reorg
16  31 invalidated transactions
21  Chain reorg invalidates previous transactions; Monero is now the attacker's tip
24  Monero witnesses existence of orphan chain; First post-reorg Monero block

For Monero blockchain consensus live status updates visit DataHoarder’s Monero Blocks⁶ and Rucknium’s Monero Consensus Status⁷ pages.

The community is currently considering various medium/long-term proposals submitted by Monero researchers and devs, including tevador’s Publish or Perish⁸ and Lucky transactions⁹, fluffypony’s Detective Mining¹⁰, and also Rucknium’s rolling DNS checkpoints¹¹ - which is a temporary emergency measure.

Join the MRL channels¹² to get involved in the technical discussions around this ongoing issue.

This is an ongoing story and the report will be updated when new information is available.

Update: Rucknium shared empirical analysis of what happened to the invalidated transactions¹³.

kivirnz creates Gupax P2Pool statistics tool

Tue, 16 Sep 2025 UTC

kivirnz¹ has created a Python Flask script² that allows XMR miners to run a live P2Pool statistics web UI with Gupax³:

All you need to do is clone the repo, install the requirements with pip and run the script with the –p2pool-path flag pointing to wherever Gupax’s included p2pool folder is, and boom!⁴

Consult the Github repository² for installation instructions and to support the project.

Note: always inspect the code before running any scripts.

[ANN] MRL: Lucky transactions (51% attack mitigation)

Mon, 15 Sep 2025 UTC

This is another proposal to bolster chain security against 51% attacks. I’m not very convinced that this should be implemented, but I think it can be discussed as an alternative to the finality layer proposal.

[ANN] Monero community input needed: Temporary rolling DNS checkpoints

Sat, 13 Sep 2025 UTC

More community input is needed on possible deployment of temporary rolling DNS checkpoints to defend against Qubic attacks. [..] TL;DR: A malicious mining pool is disrupting the network and could cause deep blockchain re-organizations. DNS checkpoints, which have existed for emergency use in the code since 2014, could prevent deep blockchain re-organizations, but Monero’s blockchain consensus protocol would temporarily be less decentralized.

[ANN] Monero Blocks

Fri, 12 Sep 2025 UTC

I have added direct Proof verification (from monero coinbase verification) [..] This currently works with either disclosed pools view keys or disclosed tx private keys for each coinbase tx. Proof is shown and can be clicked to get a full proof in an explorer. [..] Current pools: P2Pool (all public), MoneroOcean, Qubic (delayed one week). If any other pool wants to disclose their view keys they can be added, otherwise the matching is done via their public APIs and taken at face value (but not verified)

P2Pool v4.10 released with new features, fixes

Tue, 09 Sep 2025 UTC

SChernykh¹ has released P2Pool² version 4.10³ with key improvements and fixes:

[Recommended update] This will significantly reduce Monero block propagation times for all pools, not just P2Pool. Centralized pools are also recommended to run P2Pool nodes to receive and broadcast new blocks faster (one P2Pool-main node per Monero node).

Changes overview

* Broadcast all new Monero blocks through p2pool network for faster propagation
* Added --full-validation command line option to validate all Stratum shares
* [Bugfix] Get missing Monero blocks in a thread-safe way

The full list of changes since v4.9.1 is available on Github⁴.

Before using the software, you should verify the SHA256 sums with SChernykh’s GPG key⁵.

The README⁶ has valuable information about features, defaults, how pool shares work, build instructions and a short mining guide. If you need assistance, read the FAQ⁷ and join the project’s IRC channels⁸.

Note that it is strongly recommended to synchronize your system clock before you start mining.

This is an ongoing story and the report will be updated when new information is available.

Update: v4.10.1 released with bugfixes⁹.

BawdyAnarchist creates Monero PoW Simulator

Thu, 04 Sep 2025 UTC

BawdyAnarchist¹ has created Monero PoW Simulator² - a modular simulation environment that can be used to test Proof of Work countermeasures against selfish mining³ strategies:

Not only will we be able to test various countermeasures to selfish mining, but we’ll hopefully be able to test their second order effects, and maybe even learn more about how network partitioning might affect the network.⁴

Features overview

* Multi-Pool Simulation
* Pluggable Strategies
* Stochastic Network Model
* Multi Threaded
* Accurate Difficulty Adjustment

Consult the Github repository² for installation instructions.

It is worth mentioning that this project is part of the community defensive reaction⁵ to the ongoing Qubic selfish mining attack⁶ against Monero.

Note that this is the alpha release; inspect the code before using.

This is an ongoing story and the report will be updated when new information is available.

[ANN] MRL: Selfish mining mitigations (Publish or Perish)

Thu, 28 Aug 2025 UTC

Monero is currently being attacked by a malicious pool that has around 33% of the network hashrate (α = 0.33). There is no evidence that the malicious pool has reached the majority of the network hashrate. [..] This is a proposal to mitigate selfish mining. It assumes that Monero keeps RandomX as its consensus mechanism and that α < 0.5.

[ANN] Implement Detective Mining (Pool Software Change, No Protocol Change Required)

Tue, 19 Aug 2025 UTC

We should encourage pools to adopt the “detective mining” strategy from Lee and Kim, which leverages information pools already leak in their job messages to collapse a selfish miner’s private lead. Crucially, this is deployable at the pool or Stratum-proxy level with no consensus or protocol changes.

[ANN] How to quickly rent hashrate to help protect the Monero mining network using Mining Rig Rentals!

Sun, 17 Aug 2025 UTC

I made this short video to show how you can quickly rent hashrate for Monero using Mining Rig Rentals. After creating an account and depositing Bitcoin, select the mining rig of your choice and point it towards a pool. While this is not a profitable way of mining Monero, it is something we can utilize during a 51% attack.

This app would connect to an RPC node of your choice and check it every, say, 15 minutes. If a reorganization of four blocks was detected, it would send you a notification, like the National Weather Service, severe weather alerts, that would tell you that it is likely that the Monero network is under attack so you could quickly add hashrate.

kayabaNerve submits CCS proposal to write 'finality layer' book

Fri, 15 Aug 2025 UTC

kayabaNerve¹ has submitted a CCS proposal² looking to write a book about finality layers³, which might help prevent Monero blockchain deep reorganizations if ever implemented:

Summarizing here, a finality layer would be a secondary network parallel to Monero which decides Monero blocks to finalize. Once a Monero block is finalized, it’d be unable to be reorganized out of the best chain, preventing deep reorganizations. [..] The book would be made available as a web resource (such as Read the Docs) for accessibility, and to track updates via Git.

Total funding: 175 XMR.

ETA: September (end of).

Consult this week’s MRL meeting logs⁴ to learn more about ongoing discussions related to the potential introduction of non POW consensus mechanisms, which is a highly controversial topic.

To read the full proposal, share your feedback, ask questions and support this CCS, consult !604².

This is an ongoing story and the report will be updated when new information is available.

jeffro256¹ has submitted a new CCS proposal² looking to continue working full-time on Carrot³ development - Monero’s main addressing protocol post-FCMP++ - for 3 months (Q3 2025):

For this next quarter, I want to continue the work I have been doing to get Carrot/FCMP++ off the ground (see the TODO list). [..] The last quarter I finished integrating Carrot/FCMP++ transaction construction into wallet2, and tested it with CLI, RPC, and GUI wallets. I also implemented and integrated working hot-cold wallets for Carrot/FCMP++.

Total funding proposed: 123 XMR.

ETA: ~3 months.

Proposed work overview

Begin soliciting Carrot audits for protocol tweaks since first audit
Begin soliciting Carrot core implementation audits
Provide Rust implementation of Carrot for Serai/Cuprate
Solicit help for multisig implementations of Carrot
Help out with the FCMP++ integration wherever I can

jeffro256 has contributed 111 merged commits⁴ to the Monero core repository, worked on the Seraphis migration project in 2023/2024⁵, and also wrote up the Carrot specification³ for formal auditing⁶ and implementation⁷.

It is worth noting that the dev has recently completed the final milestone for their previous CCS proposal⁸.

Rucknium submits CCS proposal for 3 months of Monero statistical research

Sat, 26 Jul 2025 UTC

Rucknium¹ has submitted a new CCS proposal² to conduct statistical research for 3 more months in an effort to improve Monero’s privacy and security:

I propose to carry out research to improve Monero’s privacy & security, guide protocol decisions, and respond to Monero developer requests for statistical analysis of code changes where needed. [..] Network privacy and OSPEAD journal submission will likely be prioritized over mining pool concentration research if there is not enough time to complete all three items.

Proposed funding: 87 XMR.

ETA: 3 months.

Tasks overview

Researching how network-level privacy can be improved³
OSPEAD Journal Submission⁴
Mining Pool Concentration
tie up a few loose ends from earlier work⁵

Rucknium is an empirical microeconomist and a key Monero contributor. Consult previous Monero Observer reports to learn more about their work⁶.

To share your feedback, ask questions and support this proposal, consult !599².

This is an ongoing story and the report will be updated when new information is available.

Update: moved to funding stage⁷.

[ANN] MRL: Proof-of-Work-Enabled Relay ('PoWER')

Tue, 22 Jul 2025 UTC

128-input FCMP++ txs currently take >1s to verify on high-end machines. There is room for further optimization, however, it’s estimated that verification of high input txs will be far from instant. Additionally, creating invalid txs is effectively instantaneous. This presents a DoS vector: a malicious actor would be able to spam a node with high input junk txs, forcing the node to waste cycles verifying junk. The problem is made worse if the malicious actor has access to many IP’s.

[ANN] P2PMinerGUI - P2P Monero mining system with Python GUI

Tue, 22 Jul 2025 UTC

I’m excited to share P2PMinerGUI, a new open-source project designed to make distributed Monero mining more accessible and reliable. This is a proof-of-concept for a P2P (Peer-to-Peer) Monero mining system with an intuitive Python GUI. My goal was to create a tool that’s easy to use and provides reliable results, unlike other solutions that often complicate the process or lack stability.

P2Pool introduces reproducible builds with v4.9 release

Mon, 21 Jul 2025 UTC

SChernykh¹ has released P2Pool² version 4.9³ with support for reproducible builds⁴, various fixes and updates:

Reproducible builds help verify that the distributed binaries have not been tampered with. Anyone can independently build the software and confirm that their result matches the official release, ensuring no malicious code has been added.

Changes overview

* The release binaries are now reproducible
* 'status' console command now prints the overall node health
* 'version' console command and '--version' parameter now show versions of 3rd-party libraries used
* Updated internal dependencies

The full list of changes since v4.8.1 is available on Github⁵.

Before using the software, you should verify the SHA256 sums with SChernykh’s GPG key⁶.

Note that it is strongly recommended to synchronize your system clock before you start mining.

This is an ongoing story and the report will be updated when new information is available.

everoddandeven submits CCS proposal for Monero Python library maintenance

Sat, 19 Jul 2025 UTC

everoddandeven¹ has submitted their first CCS proposal² looking to continue working on the Monero Python library³ and release the first stable version:

I propose to finish this work by myself, as I believe that this library could significantly contribute to the entire Monero ecosystem [..] the library is essentially complete in its implementations. However, it needs to cross a testing phase through the implementation of new tests (and bug fixing), this will be the heart of my work in this 2 months.

Total funding goal: 23.43 XMR

ETA: 2 months.

everoddandeven is a Monero ecosystem contributor and the maintainer of Monero Daemon GUI⁴ and monero-ecwid⁵.

To read, share your feedback, ask questions and support this proposal, consult !598².

This is an ongoing story and the report will be updated when new information is available.

Update: moved to funding stage⁶.

hbs submits CCS proposal for EVM-based Monero atomic swaps dev work

Thu, 10 Jul 2025 UTC

hbs¹ has submitted a CCS proposal² looking to continue working on EVM-Monero atomic swaps³, develop a MoneroSwap⁴-compatible dApp and implement an automated swap manager:

During the first half of 2025 I worked on re-implementing a smart contract for doing atomic swaps between Monero and the native currency of EVM blockchains. [..] This proposal aims at providing the software pieces needed to make EVM-Monero atomic swaps even easier to use. This includes a dApp to be able to view, create and manage atomic swaps using a simple Web browser with an EIP-1193 compatible wallet such as Metamask, and a utility to optionally complete swaps automatically for the user.

Total funding goal: 135 XMR

ETA: <14 months.

Milestones overview

M1: Initial view only dApp (81 XMR)
M2: Swap creation and management (54 XMR)
~~M3: Automated swaps (96 XMR)~~

hbs is an established MoneroKon⁵ organizer with various contributions⁶ to Monero ecosystem and other open source projects.

To read, share your feedback, ask questions and support this proposal, consult !597².

This is an ongoing story and the report will be updated when new information is available.

Update 25/10/4: moved to funding stage and immediately funded (5 contributions)⁷.

4rkal submits CCS proposal to rebuild MoneroOS

Thu, 10 Jul 2025 UTC

4rkal¹ has submitted a new CCS proposal² looking to rebuild the plug and play XMR mining live operating system MoneroOS³:

MoneroOS is a simple, plug and play operating system made just for mining Monero. Think of it like NiceHashOS but for Monero. You flash it to a USB drive, boot it up, enter your wallet address, and it starts mining. [..] life got busy and I couldn’t keep up with development. Now I’ve got more time, and I’d love to rebuild it properly and add all the things I wanted to include from the start.

Total funding: 40 XMR (150 hours).

ETA: TBD.

Milestones overview

M1: Arch base + mining stack with config support (10 XMR)
M2: Web apps installer + mining config UI (20 XMR)
M3: Final ISO build with full integration (8 XMR)
M4: Documentation + walkthrough video (2 XMR)

4rkal is also the maintainer of various projects, including Cyphergoat⁴ and Donate Monero Via P2Pool (DMVP2P)⁵.

To share your feedback, ask questions and support this proposal, consult !596².

This is an ongoing story and the report will be updated when new information is available.

[ANN] Building XMR <> SOL Non-Custodial Swaps

Tue, 24 Jun 2025 UTC

Just wanted to share an update with the Monero community — we’ve finished commissioning our full XMR node, and it’s now live and operational. [..] The goal is simple: privacy-preserving swaps with no KYC, no wallet connection, no logs, and no tracking - ever. You drop in your XMR, we send out SOL. Or vice versa. No accounts, no identities, just clean execution.

Monero Talk interviews CypherStack founder Diego Salazar on FCMP++ status

Tue, 17 Jun 2025 UTC

In this Monero Talk episode¹, Douglas Tuman² interviews CypherStack³ founder and Stack Wallet⁴ maintainer Diego Salazar⁵, and researcher Luke Szramowski⁶ on the status of Monero’s upcoming FCMP++⁷ upgrade:

[..] we’re pretty happy now with divisors and we let MRL know that this past Wednesday [..] The actual issue was that Monero Research Lab wanted an answer within X number of weeks. [..] That was the whole Twitter scare of like ‘FCMPs has been delayed’. What was actually delayed by the way was the testnet. FCMPs itself was never promised at a particular time.. (Diego @ 27:20)

Several topics are discussed in this interview, including FCMP++ delay rumors, Stack Wallet features, Cypher Stack’s role in the Monero ecosystem, and other privacy projects.

It is worth noting that the FCMP++ Optimization Competition⁸ is still accepting submissions until June 30 2025 at 17:00 UTC.

Deverickapollo and napoly post first progress report for BTCPay Server Monero plugin CCS

Mon, 16 Jun 2025 UTC

Deverickapollo¹ and napoly² have posted the first progress report³ for their CCS proposal to develop a Monero plugin⁴ for BTCPay Server v2.0⁵:

Milestone 1 focused on making the plugin reliable, testable, and easy to maintain. [..] These updates prepare us for what’s next: full Monero support through a production-ready multiwallet plugin using monero-lws. [..] We’re also proud to announce that we’re the first in btcpay / monero ecosystem to achieve full plugin unit/integration test coverage!⁶

Work overview

* Full linting and code formatting for consistent development
* CI/CD pipelines to validate code and produce builds on every commit
* Deterministic builds for reproducible and auditable releases
* Comprehensive test coverage, including unit and integration tests
* Live demo and community server (xmr.btcpay.host)
* Public documentation site

Read the complete update on Gitlab and btcpay.host³.

Consult the previous Monero Observer report⁷ to learn more about the project.

It is worth mentioning that this project is still looking for funding (~143 XMR)⁸.

Note that this plugin shares a single Monero wallet across all the stores in the BTCPay Server instance. Use it only if you are not sharing your instance.

This is an ongoing story and the report will be updated when new information is available.

Tasks overview

Cuprate:
- RPC, focus on wallet support⁴
- User book⁵
- Alpha releases⁶
- Misc review, issues, PRs
Monero:
- FCMP++ integration tasks⁷

[ANN] Monero becomes top payment method on NanoGPT (private AI)

Tue, 03 Jun 2025 UTC

Monero (XMR): 47.36% (32.8% last month)
Nano (XNO): 18.45% (42.2% last month)

Hi all! I run NanoGPT, an AI service where you can access every AI model fully privately (no account needed, no KYC, can pay with Monero, we don’t store prompts/conversations). This month brings some dramatic shifts in the cryptocurrency payment landscape, with Monero achieving a historic milestone and several notable additions to our supported currencies.

wikig submits CCS proposal to create Telegram XMR wallet 'Moneropen'

Tue, 27 May 2025 UTC

wikig¹ has submitted a CCS proposal² looking to build Moneropen³, a decentralised Telegram MiniApp-based XMR wallet:

Moneropen aims to build a full-featured Monero wallet within the Telegram MiniApp environment. [..] Leveraging TMA (Telegram MiniApp) features, the wallet stores data in fully decentralized LocalStorage..

Total funding: 100 XMR.

ETA: TBD.

Milestones overview

M1: Moneropen TMA base wallet page (35 XMR)
M2: Moneropen TMA wallet system (Transfer / Hisotry) (15 XMR)
M3: Moneropen TMA feature functions (TON Proxy Wallet Node) (10 XMR)
M4: Multichain cross-chain TMA bridge (20 XMR)
M5: Monero base virtual prepaid card (20 XMR)

It is worth noting that the project has already received some criticism⁴ for using Telegram CloudStorage⁵ for user private keys and wallet data.

To read, share your feedback, ask questions and support this proposal, consult !587².

This is an ongoing story and the report will be updated when new information is available.

Update: proposal closed by wikig.

P2Pool v4.6 adds support for Tari merge mining donations

Sun, 18 May 2025 UTC

SChernykh¹ has released P2Pool² version 4.6³ with support for Tari⁴ merge mining donations⁵, various improvements and bugfixes:

[..] if you’re mining on P2Pool and update to v4.6 or a newer version, and you’re not merge mining Tari already, your node will be receiving merge mining tasks that will go to my Tari donation wallet [..] To opt out of this, build P2Pool with -DWITH_MERGE_MINING_DONATION=OFF in cmake command line.

Changes overview

New Features:
* Merge mining donation support
* Stratum local API: added wallet address
* P2PServer: show protocol version in peer list
Bugfixes:
* Fixed main thread name for debuggers and commands
* Tari: smaller reconnect timeouts
* Tari: more efficient polling
* Fixed a possible crash on shutdown
* Fixed many possible crashes throughout the code

The full list of changes since v4.5 is available on Github⁶.

Before using the software, you should verify the SHA256 sums with SChernykh’s GPG key⁷.

The README⁸ has valuable information about features, defaults, how pool shares work, build instructions and a short mining guide. If you need assistance, read the FAQ⁹ and join the project’s IRC channels¹⁰.

Note that it is strongly recommended to synchronize your system clock before you start mining.

This is an ongoing story and the report will be updated when new information is available.

[AFH] [~0.03 XMR] Send a letter from Hungary into the world

Sat, 17 May 2025 UTC

I can send letters for you from Hungary to disguise your real location. Suitable for pretending to other people that you are in Hungary. You give me a PDF with the letter you want to have sent and the recipient address. I will print it out and send it as a letter from Hungary. For an extra charge, priority shipping or tracking is also possible, but tracking is very expensive here.

I strongly suggest you STOP or demand you get the Tari from them! Right now, there are no Monero mining pools that allow you to merge-mine Tari. There are several that are working on it, but you don’t deserve to have the extra rewards for your hard-won hashrate stolen by a greedy pool operator.

atsamd21 proposes bounty for adding missing payment methods to Haveno daemon

Fri, 09 May 2025 UTC

atsamd21¹ has proposed a bounty² for adding a long list of missing payment methods to the Haveno³ daemon:

The GetPaymentMethods endpoint in the gRPC API does not return all available payment methods [..] The remaining payment methods that are available in the Haveno desktop client need to be implemented in the Haveno daemon. It’s also important that these work when creating payment accounts via the CreatePaymentAccount endpoint.

Total Bounty: ~0.6 XMR (to date)

To start working on the project yourself, you should make your intentions public by posting a comment in the bounty’s thread.

To increase the bounty you can contribute some XMR to the bounty address posted by the Monero Bounties Bot².

This is an ongoing story and the report will be updated if/when new information is available.

XMR registers 4-year high of $329 after ~40% surge

Mon, 28 Apr 2025 UTC

Monero (XMR/USD¹) bulls have successfully broken above the local resistance zone with a violent ~40% follow-up impulse move earlier today that pinged $329 for the first time since August 2021.

As I am writing this report, the reds are actively forcing the price under 275 in an attempt to block the close of a massive bullish engulfing monthly candle with only 48 hours left on the clock.

If the 240-250 support area holds, a fight for the pyshological 300 level is next. That is the final resistance before the 517 ATH.

This is an ongoing story and the report will be updated when new information is available.

plowsof considers dropping 'CCS Coordinator' role after fifth term

Wed, 23 Apr 2025 UTC

plowsof¹ has just completed² their fifth CCS Coordinator term³ and is apparently considering evolving into a more of a help the project role in the near future:

Im feeling the urge to drop my CCS Coordinator title / related tasks (other than to keep track of payout requests) and evolve into more of a help the project role where my time is spent on -site/testing gui/cli things/bounties/generally being online and poking people. We can even have other people rotate hosting bi-weekly meetings.

Work summary

[Overview]
- organized and moderated 4x meetings
- 10x proposals were move to funding stage/funded by community
[Notes]
- monero-site: put more effort into -site in time for the release deployment
- bounties: expanded my duties there

The full progress report is available on Gitlab².

Consult the previous Monero Observer report⁴ to learn more about plowsof’s CCS proposal.

This is an ongoing story and the report will be updated when new information is available.

[LTH] Hiring Monero Fuzzing Harness Developer

Sat, 19 Apr 2025 UTC

I am a committee member for the 501(c)(3) MAGIC Monero Fund and we are looking to solicit quotes for writing high quality open-source fuzzing harnesses for the Monero node and wallet RPC calls. Monero currently has basic fuzzing harnesses but we would like to expand the coverage starting with the RPC calls to help prevent any remote DOS or RCE vulnerabilities. The monero codebase is actively fuzzed by OSS-Fuzz so this proposal only requires writing the harnesses not any discovery or exploit development.

eXch instant exchange to shut down on May 1 2025

Fri, 18 Apr 2025 UTC

Top XMR KYC-free instant exchange platform eXch¹ has announced plans² to shut down its operations on May 1 2025, apparently after being targeted by an active transatlantic operation:

Recently, we received confirmation of information we had previously, thanks to some friends we have even in the state intelligence sector, that our project is the subject of an active transatlantic operation aimed at forcibly shutting our project down and prosecuting us [..] We also have absolutely no motivation to operate a project where we are viewed as criminals. This doesn’t make any sense to us. [..] Our partners will still have access to our API for a limited time, but what happens after May 1st will depend on our new management team, who will be in possession of all access to our infrastructure.

The complete announcement is available on the Bitcointalk forum². This story is also currently being discussed in r/Monero³.

openENet submits whooping 30000 XMR CCS proposal to build 'MoneroSpace' satellite network

Sun, 13 Apr 2025 UTC

openENet team¹ has submitted the largest CCS proposal² ever, looking to build MoneroSpace³ - a decentralized satellite communication infrastructure:

The MoneroSpace project focuses on open-source collaboration to fill the gap in Monero’s physical-layer censorship resistance. Despite preparation-phase challenges, our transparent development process, community-driven incentives, and robust technical solutions aim to build a decentralized satellite communication infrastructure.

Proposed funding: 30000 XMR.

ETA: 2027.

Milestones

M1: Satellite Node Hardware Design & Team Formation (7000 XMR)
M2: Radiation-Hardened Node Software Development & Compliance Preparation (8000 XMR)
M3: Satellite Prototype Testing & Spectrum Application (10000 XMR)
M4: Community Testnet Launch & First Deployment (5000 XMR)

It is worth noting that most of the project links seem to be broken currently.

To share your feedback, ask questions and support this proposal, consult !577².

This is an ongoing story and the report will be updated when new information is available.

Update: amount lowered from 30K to 550 XMR; CCS proposal closed after the recent -community meeting due to lack of support.
