P2Pool v3.6.2 was released. There were no code changes since v3.6.1, but the MacOS aarch64 build and Windows build were re-compiled with the previous compiler same as in v3.5, to fix reported stability issues.

It is said: “If the previous version works fine for you, you don't need to update.” but even if you think v3.6.1 is working, you may want to carefully monitor the situation (e.g. Hashrate / CPU temperature) to see which compiler works better for you. It is possible that keeping using v3.6.1 is better for some users.

Apparently it is not yet proven that the new compiler is the culprit for this, though a compiler optimization-related issue is suspected.

Changes:

• macOS aarch64 build is back to using old compiler (same as in v3.5) to fix reported stability issues
• Windows build is back to using MSVC compiler (same as in v3.5) to fix reported stability issues

EDIT (Clarification for Windows users)

• The previous (old) version (v3.6.1) was created with a NEW compiler, and is supposed to run faster (7-8% faster block verification), while there might be crashing bugs or other unexpected issues.
• The current (new) version (v3.6.2) was created with the OLD compiler (same as v3.5), and is supposed to run only as fast as v3.5 (so 7-8% slower block verification, than v3.6.1), although it might be stabler.

This case, alongside the proceedings against the TornadoCash developers, highlights how digital service providers and software developers are being increasingly targeted by law enforcement for offering products and services with potential for misuse despite not being directly involved in said misuse.

The Tornado Cash mixer, an Ethereum-based tool designed to conceal cryptocurrency transactions, has been in legal trouble. The founders of Tornado Cash, Roman Storm, and Roman Semenov, have been indicted on charges including money laundering and potentially face up to 20 years in prison.

[...]

The sanctions imposed by OFAC freeze any assets held in Tornado Cash and prohibit transactions to or from the service. However, effectively shutting down the service is challenging. Despite the ban, Tornado Cash continues to be used, with reports of it being leveraged for laundering unlawfully acquired crypto assets.

Those kinds of lawsuits set precedents dangerous for those involved with offering services and developing software meant to ensure privacy, anonymity, and permissionlessness — the core tenets of the cypherpunk movement that Bitcoin (BTC) was born in. Many in the crypto community raise concerns that it may lead to prosecutions against encrypted messaging services, privacy-centric cryptocurrencies, such as Monero (XMR), and web hosting services that do not snoop on their customers.

This kind of pressure may render the development of a cryptocurrency ecosystem free from control as originally envisioned much harder in a world where political dissidents, journalists, and many other vulnerable categories rely on them.

The Tornado Cash incident occurred in August, 2022, just around Monero HF. In Tornado Cash Civil Decision Limits the Reach of the Treasury Department’s Actions while Skirting a Full First Amendment Analysis dated August 25, 2023, EFF says: “A District Court recently considered a civil claim that the Treasury Department overstepped when it listed Tornado Cash on the U.S. sanctions list. This claim took some steps, if not enough, to address EFF’s concerns about coders rights.”

Windows user who'd like to try Tor + wallet etc.: if this is your first time, it may take like 10-20 minutes, but everything is easy.

Although there may be a easier shortcut (see below), the regular way is like this:

1. Go to https://www.torproject.org/download/tor/ and get a "Tor Expert Bundle" (get one that says 64 if your CPU is 64-bit). To open this ".tar.gz" file, you may need a tool like 7-zip. (*1)
2. Open (decompress) it to get a .tar; open (untar) this .tar, and you'll see two folders ("data" and "tor") there. Copy these 2 folders (with everything inside them) to a new folder, created wherever you like.
3. Open the "tor" folder, and double click on tor.exe. If asked, allow it to run and allow it to make remote connections. A text-based window (console) appears with status messages (read them to see if it's working). That's it. You're now running your own copy of Tor.

Once this is ready, you can optionally Tor-ify any tool that supports proxy (Socks5) server. Go to the "Network" or "Proxy" settings of the tool (e.g. Monero Official GUI), and input the proxy server address "127.0.0.1" (without quotes), port number "9050", and if necessary, select the type of your proxy, "Socks5". Your login name and password (if asked) can be empty or anything random (*2).

(*1) Technically, you're supposed to verify a PGP sig here. For now, let's say if you download a file from (archive.)torproject.org, it should be safe.

(*2) Similarly, you can Tor-ify other tools, e.g. a chat tool, a BitTorrent client. A regular browser can be also Tor-ified but that's a bit tricky and usually unnecessary: for web browsing, using Tor Browser is a good idea.

Official GUI vs. Feather (about Tor)

• Official GUI: Tor is not used by default. You'll have to do manual settings and run your own copy of Tor, like above.
• Feather: Tor is used automatically. That's easy. However, according to the docs, Tor is NOT ALWAYS used by default, unless you select "Always over Tor" or you're on Tails, etc. Another potential problem of Feather is, if you automatically use Tor coming with Feather, you might be stuck with an old version of Tor. This is because Tor tends to be updated more often than Feather. A solution is…

The same page states:

Feather releases are bundled with a Tor binary. If the presence of a local Tor daemon on the default port (9050) is not detected, Feather will place the bundled Tor binary in the config folder and run it on port 19450.

This should mean, if Tor is already listening to 9050, then Feather will just use it. So, if you'd like to: Feather + Latest version of Tor = also easy (just like Official GUI + Tor).

Elsewhere I saw some kind of confusion like "Feather does everything via Tor, yet it's fast" "Since Feather does everything via Tor, don't use it on Tails, which is already on Tor" etc. etc. and felt that this should be clarified and the fact should be shared. This confusion about Tails is kind of understandable, though.

A possible shortcut: If you already have Tor Browser, and if you start it, Tor Browser's Tor is listening to 9150 (I think). Thus you should be able to do wallet etc. + Tor 9150 (instead of 9050), if you don't mind always opening Tor Browser. This might feel easier…
