Ciro Santilli's hardware / Dell Inspiron 15 3520 Updated 2025-07-16

 View more

Bought May 2024 to be my clean crypto-only computer. Searched for cheapest 1 TB disk 16 GB RAM not too old on Amazon with Ubuntu certification, and that was it at £479.00.

Some reviews:

the keyboard is kind of crap. Notably the key "a" is very hard to press!!
the lack of a sleep state indication LED and "I'm powering on LED" compared to Lenovo is really sad
it gets way too hot doing work (Monero bootstrap) with lid closed, likely brought system down

OPSEC: will run only cryptocurrency wallets and nothing else. Will connect to Internet, but never ever to a non clean USB flash drive.

The OPSEC for this machine supposes:

no supply of chain attack on USB hardware, Laptop hardware, pre-installed Windows and Ubuntu ISO
connecting with browser to a few well known websites to download stuff (Ubuntu ISO, Monero software) is safe

Bootstrap OPSEC:

turn on from factory, start Windows 11 Home 23H2 build 22631.2715, connect to home Wifi during setup process. Considered skipping WiFi, but I'll want to download the Ubuntu ISO later on anyways answers.microsoft.com/en-us/windows/forum/all/bypass-lets-connect-you-to-a-network/2ce188f6-1b28-45a0-97d2-bfccfa3c9188. Don't sign in to online Windows account, and turn off all spyware requests.
on preinstalled Edge browser, download Ubuntu 24.04 ISO from ubuntu.com, check sha256 with Get-FileHash on powershell even though that is pointless security.stackexchange.com/questions/1687/does-hashing-a-file-from-an-unsigned-website-give-a-false-sense-of-security, download balenaEtcher portable from etcher.balena.io/ (currently recommended burner at ubuntu.com/download/desktop#how-to-install) from etc, and burn Ubuntu into a SanDisk Ultra Flair 64 GB
install Ubuntu from USB flash. No internet connection initially, default everything.
notice that Ubuntu 24.04 is too broken, install Ubuntu 22.04.4 on the previously used USB from Ubuntu, and then install 22.04 instead... minimal installation, encrypted ZFS
- Ubuntu 24.04 "The application files has closed unexpectedly". This likely terminated uncompression of the bz2 halfway, and led to a corrupted monerod...
- askubuntu.com/questions/15520/how-can-i-tell-ubuntu-to-do-nothing-when-i-close-my-laptop-lid fix the eternal laptop lid issue without GUI solution...
copy view only wallet private key by takinga picture of the QR code with Android cell phone. This gives it to the CIA immediately, but that's fine as we're going to publish it publicly.

It must have taken about one week running full time to sync the Monero blockchain which at the time was at about 3.1M blocks! I checked on system explorer, and CPU and internet usage was never maxed out, suggesting simply slow network. But the computer still overheated quite a bit and froze a few times.

This is mostly stuff from before 2016 when Ciro was anxious to document his contributions to get a job.

Most of the projects here are also minor contributions, or Ciro later noticed that the projects were not useful enough to work on and that he was actually wasting his time.

All found so far are also reproduced at: asciiart.website/index.php?art=people/naked%20ladies therefore not blockchain original.

Some of the very first ASCII art present in the blockchain besides BitLen is porn. Surprising?

Cool data embedded in the Bitcoin blockchain / Eternity Wall Updated 2025-07-16

eternitywall.it

This website used to allow embedding text messages with OP_RETURN, here's an archive from 2015: web.archive.org/web/20150718052659/http://eternitywall.it/

As of January 2024, it seems to read-only mode, where it simply indexes matching transactions that were made via other means: web.archive.org/web/20230929075331/https://eternitywall.it/

A Reddit announcement from July 2015: www.reddit.com/r/Bitcoin/comments/3dxy9f/eternity_wall_messages_lasting_forever/

There were 3191 hits for the search term:

git grep '\bEW '

in our data starting with tx a3b3af21514bd79a4cbcac9916a8514636a72d813539192214542fd85247082e (2015-06-24):

up to the last entry on tx 28820bc14cf2cfda58ecbc9ac6df3f41a1cb90f4246543f01ba42a5e9dac3cf8 (2023-06-15)

EW May our friendship endure, signed by hg, kty, wjj, and xyz.

no doubt initials of 4 Chinesepeople. A blood brother oath comes to mind, akin to the Oath of the Peach Garden. Will these four be the ones to take down the evil dictator Xi Jinping?

The very first message gives away the name of what we assume is a web-based upload system, "EW" being its advertisement signature added to every message.

Running bitcoin-cli:

bitcoin-core.cli getrawtransaction a3b3af21514bd79a4cbcac9916a8514636a72d813539192214542fd85247082e true

shows that the messages are encoded with OP_RETURN:

  "vout": [

      "n": 0,
      "scriptPubKey": {
