The “2008-2009 Creation” section links to https://www.wired.com/story/after-10-years-bitcoin-changed-everything-nothing/ when referring to the initial announcement on the “Cryptography” mailing list. I’d like to suggest to (also?) link directly to that mailing list archive of that very post: https://www.metzdowd.com/pipermail/cryptography/2008-October/014810.html Jschauma (talk) 09:00, 8 April 2026 (UTC)Reply

This is a primary source: not ideal. a455bcd9 (Antoine) (talk) 15:31, 8 April 2026 (UTC)Reply

One of the sentences in the lead has a really big link for just one thing, which I think is a bit distracting:

- From 2021 to 2025, El Salvador adopted it as legal tender currency before revoking it.

I suggest we shorten it to:

- From 2021 to 2025, El Salvador adopted it as legal tender currency before revoking it.

Conflict of interest edit request: Physical Bitcoin art

I would like to suggest adding a short neutral paragraph about physical Bitcoin art to the article, possibly in a culture-related section. I may have a connection to one of the artists/projects mentioned in the sources, so I am requesting review instead of editing the article directly.

Suggested text: Physical Bitcoin art is a form of visual or material art inspired specifically by Bitcoin, rather than by cryptocurrency or non-fungible tokens in general. It may include handmade works such as embroidery, painting, textile art, sculpture, prints, or objects that reference Bitcoin’s monetary system, decentralization, mining, cryptography, scarcity, and Satoshi Nakamoto. Some artists and curators describe this approach as Bitcoin-only and separate from NFTs or other cryptoassets.

We would need non-cryptocurrency website sources for this one. Vgbypw (talk) 14:40, 15 June 2026 (UTC)Reply
Thank you. I understand that cryptocurrency-related sources are not enough for this request.
Would the following non-cryptocurrency / art-related sources be more appropriate?
Sidorova, E. “The Cyber Turn of the Contemporary Art Market” — discusses the 2018 Paris exhibition “Bitcoin Art (R)evolution” in the context of the contemporary art market.

Thank you! Of these, only the article by Elena Sidorova is a true RS. Unfortunately, it only mentions 'bitcoin art' as a part of the quoted art exhibition's name, and doesn't use it as a standalone term otherwise. DMINTI source is 50/50 in my opinion. I think it's too weak to for this entry. Perhaps other editors have something else to say on this topic. Vgbypw (talk) 15:56, 15 June 2026 (UTC)Reply
Thank you. I understand.
I looked for more non-cryptocurrency sources. I agree that these sources may not be enough for a separate “Bitcoin art” section.
Maybe a smaller sentence about Bitcoin in contemporary art and the art market can be better.
I found these sources:
ARTnews, “MAK Vienna Becomes First Museum to Use Bitcoin to Acquire Art”
https://www.artnews.com/art-news/market/mak-vienna-becomes-first-museum-to-acquire-art-using-bitcoin-a-harm-van-den-dorpel-3995/

https://www.mak.at/jart/prj3/mak-resp/data/uploads//downloads/presse/2015/Harm_van_Dorpel_e.pdf
Elena Sidorova, “The Cyber Turn of the Contemporary Art Market”
https://www.mdpi.com/2076-0752/8/3/84
Furtherfield, “Artists Re:Thinking the Blockchain”
https://www.furtherfield.org/artists-rethinking-blockchain/
The Guardian, “Simon Denny: the artist explaining blockchain with Pokemon”
https://www.theguardian.com/artanddesign/2016/aug/26/simon-denny-artist-blockchain-pokemon
Surface Magazine, “Simon Denny Decodes Bitcoin”
https://www.surfacemag.com/articles/artist-simon-denny-petzel-gallery/
Maybe this smaller text can be acceptable:
“Bitcoin has appeared in contemporary art and the art market as a subject, a payment method, and a technology used for provenance. In 2014, Hyperallergic reported on Cointemporary, an online art gallery where artworks could only be bought with Bitcoin. In 2015, ARTnews reported that MAK Vienna became the first museum to use Bitcoin to acquire an artwork. Academic writing has also discussed exhibitions and artworks connected with Bitcoin, blockchain, and the contemporary art market.”
Thank you for your time and help. ~2026-35121-06 (talk) 16:09, 15 June 2026 (UTC)Reply
I found one source from Mozilla Festival. It says that “Bitcoin Threads” is a hand-embroidered art installation by Aksana / 5Ksana.
https://pretalx.com/mozilla-festival-2025/talk/GKAQQN/
This source can show that the artwork was part of Mozilla Festival. ~2026-35121-06 (talk) 16:23, 15 June 2026 (UTC)Reply
None of the websites given here counts as mainstream media coverage, and therefore probably fails WP:DUE. 海盐沙冰 / aka irisChronomia / Talk 19:03, 15 June 2026 (UTC)Reply
Thank you. I understand the WP:DUE concern.
I looked again for stronger mainstream media sources. I found some better sources, but I understand that they may still not support a separate “Bitcoin art” section.
The strongest source I found is Bloomberg Businessweek. It uses the phrase “Bitcoin-art-puzzle phenomenon”. It also says that these artworks started to enter the mainstream through galleries, museums, international exhibitions, and video games. It also mentions the Paris exhibition “Bitcoin Art (r)evolution”.
I also found The Guardian and SFGate articles about Kuno Goda’s work “200 Bitcoins”. These articles show Bitcoin as a subject in physical/pop art.
I found Reuters and Financial Times sources about Bitcoin and cryptocurrency as payment in the art market.
Maybe a smaller text would be more neutral:
“Bitcoin has appeared in contemporary art and the art market as a subject and as a payment method. Examples include Bitcoin-themed artworks and art sales where Bitcoin was accepted as payment.”
Possible sources:
Bloomberg Businessweek / Olga Kharif, “Your Bitcoins Are Hidden in the Painting”

These are indeed interesting, perennial sources, especially for the Guardian piece; I would be looking into it later and see how the article should address these reports.
Thanks, again, for the sources. 海盐沙冰 / aka irisChronomia / Talk 16:06, 16 June 2026 (UTC)Reply
Thank you very much for your time and for looking into it.
I understand. I will wait and will not add more comments now.
Best regards. ~2026-35121-06 (talk) 16:16, 16 June 2026 (UTC)Reply
I think the Guardian piece is interesting, since an artwork about bitcoins being sold for bitcoins is probably worthy of a mention in an article about ... well, bitcoins.
The reuters piece seems a bit short for me (on its own), but I think together they do support the sentence “Bitcoin has appeared in contemporary art and the art market as a subject and as a payment method. Examples include Bitcoin-themed artworks and art sales where Bitcoin was accepted as payment.”. I'll append the guardian piece behind the sentence as an example, I think. 海盐沙冰 / aka irisChronomia / Talk 18:56, 17 June 2026 (UTC)Reply
I can't find the FT piece's original text, as they're not successfully archived in the Wayback machine. Found it, here is the full text via ByebyePaywall: [1]. Too sleepy, I'll be reading it tomorrow. 海盐沙冰 / aka irisChronomia / Talk 19:01, 17 June 2026 (UTC)Reply
Thank you for checking this.
I agree with your idea. The Guardian piece is a good example. Together with Reuters, it supports the sentence about Bitcoin in contemporary art and the art market.
Thank you also for checking the FT piece. I can help look for another reliable and accessible source if needed. Alexbtcfree (talk) 19:17, 17 June 2026 (UTC)Reply
Hi, how are you? I hope you’re doing well. I just wanted to kindly ask if there are any updates. Alexbtcfree (talk) 13:49, 23 June 2026 (UTC)Reply
I think WD:DUE is... how to put it nicely? It has it's time and place. Globally crypto is still a nieche topic and use case. It's obvious a subproduct will be even more nieche. BUT what's important is that money exchanges hands. People earn money. And money is what moves the world - if you don't believe it look at US politics influenced by billionares. If the sources are thurstworthy and people regularly make money from it it's logically relevant enough regardless of the fact mainstream media doesn't talk about it.~2026-39396-77 (talk) 18:09, 14 July 2026 (UTC)Reply
Thank you. I agree with your point. I think reliable sources are more important than mainstream media. Thank you for your explanation. Alexbtcfree (talk) 18:13, 14 July 2026 (UTC)Reply
Wikipedia policy doesn't bas content decisions on what some random contributor thinks is 'logically relevant', or on facile commentary on economics. AndyTheGrump (talk) 18:15, 14 July 2026 (UTC)Reply
[2]: "DeCourcelle started the Bitcoin-art-puzzle phenomenon in 2014 with Dark Wallet Puzzle, a painting of two leading crypto anarchists that hides a key. It led to a 3.4-Bitcoin reward.

Mention Q day bitcoin vulnerabillity?

Seems pretty big. ~2026-37604-05 (talk) 22:34, 29 June 2026 (UTC)Reply

Nothing about Bitcoin makes it more vulnerable than any other system of financial security. That's more of a quantum computing thing than a Bitcoin thing, unless there is already a Q-Day section on every other form of digital security. Idacticus (talk) 04:03, 19 July 2026 (UTC)Reply

scaling debate, big backlog in transactions

  • [3] BIP 148, BIP 91 (SegWit2X)
  • Bitcoin Unlimited has emerged due to the backlog problem, value of Bitcoin plummeted[4] [5]

Reading this articles it's obvious this was one of the major milestones and problems in Bitcoin history and among community. The article doesn't represent this appropriately enough, doesn't even mention most of the stuff. It'd be good if someone with crypto understnading updated the article. ~2026-39396-77 (talk) 18:01, 14 July 2026 (UTC)Reply

Fix technical error relating to block hashes

The line:

Each block contains a SHA-256 hash of the previous block,[1] chaining them in chronological order.[2]: ch. 7 [1]

should be changed to:

Each block contains a double SHA-256 hash of the previous block header,[1] chaining them in chronological order.[2]: ch. 7 [1]

This is consistent with the article's own infobox that says "SHA-256 (two rounds)". Harrigan (talk) 19:18, 6 August 2026 (UTC)Reply
