I wouldn't call it critical since the maker would still do on-chain verification for the UTXO and fail then. Nonetheless they are all great findings that should be fixed!

FYI: None of the bugs are critical, it's better to catch invalid transactions early, but at the end there is the Bitcoin network to reject those.

What do you mean by spreading out UTXOs?
A SegWit output is as secure against QC with or without CoinJoin'ing.
Addresses should not be reused anyway. So until spent, the PubKey is not public and thus not susceptible to being broken by QC or anything else.
About plausible deniability: privacy is not a crime! And a very legit thing to worry about. For better or worse, you're always able to prove the trace of your coins through CoinJoins. So it's up to you to reveal it selectively.

It's a bit more than that. In the JoinMarket protocol, the taker coordinates the transaction and is the only one that knows the inputs -outputs mapping. So you don't have to "trust" the makers with your privacy. But you're vulnerable to Sybil attacks. If all randomly cuosen makers were controlled by the same entity, they could know the inputs-outputs of the taker (or at least gain some info about it).
The protection from these kind of attacks is adding a cost to creating offers. JM uses fidelity bonds for that (timleocked Bitcoin) and incentivizes larger bonds than several small ones.

The Git protocol shines due to its decentralization. There is no reference copy of the repo and it's perfectly fine to have as many copies as you want.
NostrGit recommends disabling issues and PRs in GitHub to have them in a single place, but it's not a technical limitation, just for operational ease.

I don't like the idea of "tainted" coins. Following your thoughts about gypsies, do you think they care where the gold they own comes from? Should you?
It's not your problem that some exchange does not accept certain UTXOs. It's fiat slaves' problem. The problem to be fixed is being a fiat slave, not Bitcoin's fungibility.
As a free individual you should just care about privacy. And CoinJoin is a great tool for that. About "bad" coins, wouldn't you get some if sold at a discount?
What really helps fungibility is the lightning network. Use coinjoined funds to open a channel and enjoy L1 privacy and spending privacy and fungibility.
The "weakness" of Bitcoin in terms of privacy and fungibility can also be seen as a positive thing. Make something like Monero that is great in both fungibility and privacy and congratulations, you no longer have the problem of good and bad coins. They're all bad now🤣 and no exchange will accept them.

2026-03-27 10:50:09 UTC

very interesting tool: https://am-i.exposed/#tx=6cb2433f28177a3b07073a0eb34a527ba6d7dd7483cccb394f88321373c0ed20
that's a big joinmarket transaction. it's interesting to see where funds come from and where they go. it incorrectly flags a change spent together with an equal amount, which is not really linking but probably just different makers
keep in mind that it uses mempool.space API! don't use this tool directly for your transactions (use tor and even better your own mempool API)

2026-03-21 12:46:18 UTC

Controversial take: cash is actually pretty great
widely accepted, tons of privacy, good denominations for change, etc.
And the inflation EUR or USD suffers in a week/month is negligible.
I would prefer paying through LN at physical stores for convenience, but then the merchant loses privacy vs cash, and payments would fail more often.
So I'd say the priority isn't to kill the only form of fiat that actually offers something. But to streamline Bitcoin on/off ramps
and obviously setting up ATMs would be relatively easy (there are already many), but having to show your ID (in Spain) for that... Again something that's technically feasible but blocked by regulations.
Same for traveling, the most convenient way to get local currency abroad is a BTC ATM.

Do you ever wonder why people use stablecoins?
Should people use Bitcoin because they're forced to or because they want to?
A few "legit" use cases of USDT come to mind:
1. Some people can simply not handle any volatility. Not because they're "weak" or "dumb", just because they are poor. They have bills to pay and no margin. Those bills might not even be denominated in USD. But any currency has lower volatility against USD than against Bitcoin.
2. Electricity is denominated (or highly tight to) USD. I have some hosted Bitcoin miner in UAE. No hosting accepts Bitcoin. They have tight margins, and Bitcoin volatility can often beat their margins. So now I have to resort to remote custodial exchanges (at least without KYC) to swap Bitcoin through LN and send the hosting USDTs.
I don't want USDT. I don't want to hold them or touch them in anyway. But I clearly see why other people would, and I'm happy that there's now a more sovereign way for me to give USDT to whoever wants them, without KYC or cudtody risk.
And it goes both ways! It's now easier to swap USDT for Bitcoin. What's next is to keep improving and building the Bitcoin ecosystem, so that people choose to swap in that direction more often than the other. If this is not the case, the problem is not the bridge.

The problem with insufficient entropy at boot time:
> In 2012, researchers scanned the whole internet and harvested public keys from TLS certificates and SSH hosts. They found that a handful of systems had identical public keys, and in some cases very similar keys (namely, RSA keys with shared prime factors): in short, two numbers, n = pq and n′ = p′q′, with p = p′, whereas normally all ps and qs should be different in distinct modulus values. After further investigation, it turned out that many devices generated their public key early, at first boot, before having collected enough entropy, despite using an otherwise decent PRNG (typically /dev/urandom). PRNGs in different systems ended up producing identical random bits due to a same base entropy source (for example, a hardcoded seed).
From the book Serious Cryptography.

> The 2G standard also defined A5/2, a cipher for areas other than the EU and US. A5/2 was purposefully weaker to prevent the use of strong encryption everywhere.
From the book: Serious Cryptography.
So basically they made 2G A5/1 cypher insecure accidentally, but from the beginning designed a weaker A5/2 for the rest of the world on purpose...

Don't want to start a war. Just to mention the truism that different tools have different tradeoffs and that does not mean one is better than the other.
That being said:
- (Current) Bitcoin had no hard forks
- Bitcoin is protected by a hashrate that's orders of magnitude larger and that can't be outpaced with generic hardware
- Higher cost to validate transactions (in CPU, RAM, and tx size)
- Bitcoin has a limited supply. NGU technology is very important for a SoV! And nice to have for a MoE.
- Monero has no layer 2, protocols are built in layers and blockchains don't scale
All of this might be worth it for some particular person doing some particular task, but the privacy gains are not a free meal!

Well, the taker is the coordinator. I would not call that a centralized coordinator.
It's not always the same entity, and no one other than the taker knows the input and output mappings or can easily perform a Sybil attack.
Not sure if it can get much better than this from the taker's perspective.

I managed to fix it by running a newer version than what was avaialble at the Debian repos.
It's now at 83% sync. It's running on my home server on an nvme with gigabit internet, so the conditions are pretty good.
Here is the command in case it helps anyone:
```
docker run -d --restart always --name monerod -v /flash/monero/:/home/monero/.bitmonero --user 1000:1000 --network "container:gluetun" ghcr.io/sethforprivacy/simple-monerod:v0.18.4.5 --rpc-restricted-bind-ip=0.0.0.0 --rpc-restricted-bind-port=18089 --no-igd --no-zmq --enable-dns-blocklist --ban-list=/home/monero/ban_list.txt
```
It's more or less the recommended parameters from the Docker image repo, with the addition of running it as unprivileged and behind a VPN (gluetun).

I see. IMO there's no perfect solution, just different tradeoffs.
I haven't personally thought much about the spam debate. My (ignorant) view is that fees are too cheap and that's the consequence of a bigger problem (lack of adoption and MoE through self custody). Maybe that's what we should focus on instead.
I would expect that with 10x or 100x fees, spam would just be priced out. Another point is that it kind of “helps” to have a baseline “security budget” sponsored by bored people. Cool, whatever.
I generally don't like the idea of saying what a system/protocol is “for”. With a hacker mindset, I admire when someone finds a new use to an existing thing. For example, hash algorithms are not meant to be used for anything like Proof of Work, but it's amazing how well they fit.
Not saying that embedding pepe images on Bitcoin transactions is that “hacker” breakthrough. But who knows what people will come up with in the future.
Please, educate me on whatever I'm missing. Really haven't put much thought into it. The topic looks so “hot” and politics-like that just pushes me away.

No, that's just the inverse of interest rates. Things with a long time horizon and unclear profitability like tech products (e.g., the metaverse or whatever) just hire more when money is cheap and cut costs when it's expensive. They are not in a rush and it's unclear if delivering one year earlier is worth a 5% higher cost.

I think the question should be how to coordinate so Bitcoin has (more) layer one privacy and fungibility.
All that Bitcoin cares about is that in each block all transactions are valid. “Nothing” stops us from making a single transaction per block with all inputs and all outputs arranged in a way that subset sum analysis is broken. Not the same as Monero's ring signatures, but both for good and for bad.
And then of course move as far away from the base layer as possible, because blockchains don't scale.
IMO Monero just chooses different tradeoffs and pushes the scalability problem further, but does not solve it.

Xiaogang, Anhui - Wikipedia
https://en.wikipedia.org/wiki/Xiaogang,_Anhui
> In December 1978, eighteen of the local farmers, led by Yen Jingchang, met in the largest house in the village. They agreed to break the law at the time by signing a secret agreement to divide the land, a local People's Commune, into family plots. Each plot was to be worked by an individual family who would turn over some of what they grew to the government and the collective whilst at the same time agreeing that they could keep the surplus for themselves. The villagers also agreed that should one of them be caught and sentenced to death that the other villagers would raise their children until they were eighteen years old. At the time, the villagers were worried that another famine might strike the village after a particularly bad harvest and more people might die of hunger.
> After this secret reform, Xiaogang village produced a harvest that was larger than the previous five years combined. Per capita income in the village increased from 22 yuan to 400 yuan with grain output increasing to 90,000 kg in 1979. This attracted significant attention from surrounding villages and before long the government in Beijing had found out. The villagers were fortunate in that at the time China had just changed leadership after the death of Mao Zedong. The new leadership under Deng Xiaoping was looking for ways to reform China's economy and the discovery of Xiaogang's innovation was held up as a model to other villages across the country. This led to the abandonment of collectivised farming across China by 1983 and a large increase in agricultural production. The secret signing of the contract in Xiaogang is widely regarded by historians and media as the beginning of the period of rapid economic growth and industrialisation that mainland China has experienced ever since.

Happy to follow you and to see some contrarian opinion.
Bitcoin's value comes from being decentralized ans secure, and that hasn't changed. Bitcoin promises: censorship resistance, absolute property, ...
NGU is great, but it's not guaranteed or even the biggest value proposition.
Doing as well as the SP500 in the worst time frame that you could pick is still a great baseline. I think most people here would be willing to give up a few percentage points for the sake of sovereignty. Those percentage points would have been taxed away or confiscated somehow anyway in the KYC'd SP500 shares.
It's very unrealistic to expect for a 2T market cap asset to just go up and to the right unbothered.

Haven't found you yet. But you can find me as well. I'm wearing an "opt out" t-shirt.
BTW, should we set up a table with a sign saying "open spurce self hosted money (Bitcoin), yay or nay?". Really sad to not see anything about Bitcoin here. And I think the general attitude towards it is negative. Maybe we should get the debate started.

I looks like it has stopped now. Check your log file size just in case (maybe you didn't notice?).

Dumb me! Of course! Overcomplicating what isn't complicated...
Then yes, the only problem to solve there is the custodial risk.
I think Tornado Cash privacy properties are amazing (not considering Ethereum RPCs and other risks). Dreaming about something similar on some Bitcoin layer one day.

@nprofile…h36r has it ever been considered to enable Touring complete (or closer to) spending condition scripts on cashu mints? As in smart contracts that could enable ZKPs for spending, allowing for something like Tornado Cash but on Bitcoin.

What they've added only later is the possibility to enable PoW for hidden services created through RPC via ADD_ONION. Before it was only possible through the torrc file, but makers use ephemeral onion addresses for privacy.

If logs don't fill up disk space that's a big win. But the moment you get targeted CPU usage will also be a problem :/

There's someone flooding all JoinMarket makers with !orderbook requests. Making them run out of storage with several GBs of logs per hour and also filling their CPU cycles. It does so through direct onion connections (last time was through directories) and with a bunch of nicks in parallel.
I've implemented Tor level DDoS protection through a dynamic PoW requirement (0 in normal cases) in a branch of jm-ng as an experiment: https://github.com/m0wer/joinmarket-ng/pull/108/changes It only works with the alpha release of Tor, but an expected release might come soon.
I didn't know about this feature from Tor, but it's really neat. Some more info here: https://community.torproject.org/onion-services/advanced/dos/

Yes, it seems to have come back again. I guess there will be a painful transition period to JM-NG which fixes the problem with rate limiting in directories and makers/takers.

About the problem of deleting notes on Nostr, here's an idea: use a delegated key that rotates each month and expires. Once expired, request deletion from all your notes from all relays and then share the private key so that anyone can post bullshit with it, including yourself.
You get plausible deniability for anything posted before last month and really encourage relays to delete all shit signed with that expired delegated key or they will get spammed to death.
This might be a stupid idea. Please go ahead and let me know why.

Fixed my zap receiving ability by switching to Coinos. Will leave the fight of getting my self hosted lnbits working fast enough for later.

Thanks! very useful.
I've changed my zaps address to a Coinos one and works well now.

Hi @nprofile…asma ! Any way I can reach out to you for some questions about JoinMarket development? Tried email and telegram but I think you're not active there anymore.

No external audit yet. I'm trying to get funding for that. And also looking for more eyes on the code on the day to day. If you know anyone interested for either please let me know.
For the adoption, I'm the only maker at the moment with some bot for mainnet tests. The NG orderbook has peer feature detection. Any maker with features is a NG maker: https://joinmarket-ng.sgn.space/
So sadly no active users, just people trying out stuff (and helping me a lot with catching bugs and improving UX). A bit of a chicken and egg problem.
What's working great is the new orderbook watcher in general and the two NG directory nodes, that were the only ones to resist some DoS attack recently.

All an existing maker needs it's the mnemonic! There is also fidelity bond auto discovery. And next in the roadmap is supporting external storage as fidelity bonds. So makers can start saving bonds in cold storage or reuse existing ones without reusing the mnemonic. In fact a maker could run both the reference implementation and JM-NG with different wallets and the same bond for experimenting.
Manual steps here: https://github.com/m0wer/joinmarket-ng/tree/master/maker#migrating-from-joinmarket-reference-implementation

JoinMarket NG 0.10.0 release is out!
Lots of news and improvements. Here are the highlights:
- Descriptor wallet (syncs in seconds). No private keys stored in the Bitcoin Node.
- `--select-utxos` a TUI for `jm-taker coinjoin` and `jm-wallet send`.
- External notifications compatible with every service (Gotify, Telegram, ...). Specially useful for makers. Uses apprise.
- Configuration file for clear and persistent settings.
