The lack of commercial deployments[edit]

I was going to add the following however I note that it was written 10 months ago. Include or not? The lack of commercial deployments for blockchains has been attributed to their expense, complexity and inefficient energy use.[1]

Unreadable to the uninitiated[edit]

For someone uninformed about the general subject matter who, say, simply wants to understand what blockchains are sufficiently to comprehend the text in which they first saw it used, this article is useless. It gives no actual explanation of what they actually are, and only confuses further by using a plethora of what some might call additional technical mumbo jumbo. There's plenty of room for that stuff, but the introduction should at least in part be used to give context to the topic, explain the very basics and give a small number of tangible, comprehensible facts which help readers place blockchains in a sort of mental category, before the article delves into rattling off all the theoretical specifications, history and various uses of blockchains.

Proposed merge of Blockchain-based database into Blockchain[edit]

The subject is not particularly notable to warrant a separate article of its own, and there are substantial overlaps between the two articles. Mopswade (talk) 10:48, 22 April 2020 (UTC)

The sources referenced in the Blockchain article claim that a blockchain is a database. Thus, the "blockchain-based database" term is similarly meaningful as a "database-based database" term. Are you sure that the sources using this problematic term are reliable and independent? Ladislav Mecir (talk) 11:44, 22 April 2020 (UTC)
@David Gerard: comments on this? The merge looks logical to me at first glance, as I thought that all blockchains were a database by definition. Thanks! Jtbobwaysf (talk) 12:38, 22 April 2020 (UTC)
I mean, they're definitely a datastore, and I've never heard "blockchain-based database" used as a technical term. Looking at Blockchain-based database, it's not clear why anyone would do this ... but I'd say that article should be a section of this one - David Gerard (talk) 17:19, 22 April 2020 (UTC)
I checked the text of the article proposed to be merged. As far as I can tell, the only source mentioning the "blockchain-based database" term is [1], while the source [2] and other sources use the standard blockchain term instead. When merging, I think that we should use the standard blockchain term when referring to such databases exactly as, e.g. the source [2] and many other sources do. Ladislav Mecir (talk) 05:35, 23 April 2020 (UTC)
Guys! This article somewhat mixing new blockchain tech with old database tech. And, we are looking at a very new application or an iteration.[3][4] At present, I am not sure whether this topic deserves a separate article or not. But, it does have the potential to have one in the near future. - Hatchens (talk) 15:40, 24 April 2020 (UTC)
For everyone's attention, this particular source [5] is talking about Blockchain relational database. And, it is explaining the same concept as mentioned in the article (which we intend to merge). - Hatchens (talk) 16:19, 24 April 2020 (UTC)
Normally we dont cover these 'new' concepts at wikipedia. I support merge as this content would be fine in the existing article. Thank you! Jtbobwaysf (talk) 18:52, 24 April 2020 (UTC)

Blockchain based databases, as listed in the article, seem to just be the databases used to store the chain of blocks that makes up a blockchain. To the best of my understanding, a blockchain is just a linked chain of data that’s secure because each piece of data references the last piece of data, making it impossible to tamper with, and all of these “blockchain databases” are just databases that are used to to create / store a blockchain. I agree these articles should be merged. Mattgallea (talk) 03:39, 12 May 2020 (UTC)

usage: blockchain phone, blockchain OS[edit]

World’s First True Blockchain Phone is “BOB,” which stands for “Blok On Blok.” -users will be able to switch between Android and blockchain modes on their phones. BOB has its own blockchain operating system or OS, called Function X or f(x). When BOB is set to blockchain mode, every bit of data sent through the phone is executed through a blockchain, which makes BOB the first truly blockchain-powered phone in the world. [1]

First blockchain phone call was made in 2018[2]

there were prior to that " blockchain-based" phones but were really more blockchain-focused phones starting with HTC. [3] [4] — Preceding unsigned comment added by 89.201.184.8 (talk) 02:08, 27 April 2020 (UTC)

Blockchain is a time-stamped series of digital ‘blocks’ where each block contains a record of valid transactions, i.e. a digital ledger. Each block of data is secured and bound to each other using cryptographic principles LUOLKW (talk) 15:16, 12 May 2020 (UTC)

 Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. Where and how does this go into the article? @LUOLKW: RandomCanadian (talk | contribs) 15:28, 12 May 2020 (UTC)

Semi-protected edit request on 13 May 2020[edit]

Change "A blockchain is a decentralized, distributed, and oftentimes public, digital ledger that is used to record transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks." to "A blockchain is a time-stamped series of unalterable blocks of data that are managed by a cluster of computers where the blockchain network has no central authority."

Description of the edit: The old version is obsolete

[1] LUOLKW (talk) 00:43, 13 May 2020 (UTC)

blockgeeks.com is not a source that we want to rely on. Thank you very much. Retimuko (talk) 01:09, 13 May 2020 (UTC)
The "unalterable blocks" wording is problematic and, as noted by Retimuko, not confirmed by a reliable source. Ladislav Mecir (talk) 06:09, 13 May 2020 (UTC)

Please change "A blockchain is a decentralized, distributed, and oftentimes public, digital ledger that is used to record transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks.[1][17] This allows the participants to verify and audit transactions independently and relatively inexpensively.[18] A blockchain database is managed autonomously using a peer-to-peer network and a distributed timestamping server. They are authenticated by mass collaboration powered by collective self-interests." to "Blockchain is a time-stamped series of digital ‘blocks’’ with each block contains a record of valid transactions. The blocks are encrypted and linked with one another using cryptographic principles. The core concept behind the blockchain network is that it is decentralised across peer-to-peer network allowing participants to confirm the transactions without the need of a central certifying authority. The information is open for the involved participants to see. "

Seems to me that these two versions say pretty much the same thing but that the current version is more descriptive. – Thjarkur (talk) 11:34, 23 May 2020 (UTC)
The proposed change does not look like an improvement to me. Ladislav Mecir (talk) 22:21, 23 May 2020 (UTC)
