WARNING: ACTIVE COMMUNITY SANCTIONS

The article Cryptocurrency, along with other pages relating to blockchain and cryptocurrencies, is designated by the community as a contentious topic. The current restrictions are:

Limit of one revert in 24 hours: This article is under WP:1RR (one revert per editor per article per 24-hour period)

Editors who repeatedly or seriously fail to adhere to the purpose of Wikipedia, any expected standards of behaviour, or any normal editorial process may be sanctioned.

Remedy instructions and exemptions

Enforcement procedures:

Violations of any restrictions (excluding 1RR/reverting violations) and other conduct issues should be reported to the administrators' incidents noticeboard. Violations of revert restrictions should be reported to the administrators' edit warring noticeboard.
Editors who violate any listed restrictions may be blocked by any uninvolved administrator, even on a first offense.
An editor must be aware before they can be sanctioned.

With respect to any reverting restrictions:

Edits made solely to enforce any clearly established consensus are exempt from all edit-warring restrictions. In order to be considered "clearly established" the consensus must be proven by prior talk-page discussion.
Edits made which remove or otherwise change any material placed by clearly established consensus, without first obtaining consensus to do so, may be treated in the same manner as clear vandalism.
Clear vandalism of any origin may be reverted without restriction.
Reverts of edits made by anonymous (IP) editors that are not vandalism are exempt from the 1RR but are subject to the usual rules on edit warring. If you are in doubt, contact an administrator for assistance.

If you are unsure if your edit is appropriate, discuss it here on this talk page first. Remember: When in doubt, don't revert!

Is Cryptocurrency traceable to where and when it was minted?[edit]

I understand legal tender usually has this property. Does each unit of cryptocurrency contain an indelible reference to the date/time and computer/node on which it was originated and thereby to the real territory/jurisdiction (or multiple?) in which the computer/network was located? What about crypto mined in international waters? Is the information encrypted or public? Is this maybe a differentiator and a way to classify different types of cryptocurrency? How is this solved for the classic, Bitcoin? A table listing the features of various popular cryptocurrencies and what info is public and what is private would enhance the Wikipedia article.

Each unit of cryptocurrency, including Bitcoin, contains a unique identifier called a "transaction ID," which records the time and date of the transaction, the sender's address, the recipient's address, and the amount transferred. This information is stored on a distributed ledger, which is a public and decentralized database shared among all nodes in the network.

The distributed ledger ensures that the transaction records are immutable, tamper-proof, and transparent, as every node in the network maintains a copy of the ledger. Therefore, the jurisdiction of the cryptocurrency is determined by the location of the nodes that maintain the ledger.

Crypto mined in international waters would still be subject to the same rules and regulations as any other cryptocurrency, as it would be recorded on the blockchain, which is accessible to anyone with an internet connection.

The information on the blockchain is encrypted to protect the privacy of the users, but the public ledger still allows for a degree of transparency. For example, while the sender and recipient's identities are not recorded on the blockchain, their addresses are visible.

Different cryptocurrencies may have varying levels of transparency and privacy, depending on the design of their respective blockchain networks. Some cryptocurrencies, like Monero, are specifically designed to provide greater anonymity and privacy for users.

A table listing the features of various popular cryptocurrencies, including their level of transparency and privacy, would be a useful addition to the Wikipedia article. It would help readers understand the differences between different cryptocurrencies and make informed decisions about which ones to use.

Is it against the rules to ask for help to teach science ?[edit]

Don't use the talk page for general discussion. See WP:NOTAFORUM for more information.

The following discussion has been closed. Please do not modify it.

I told Wikipedians I want help to teach science about cryptos. Is it against the rules to ask for such help ? TD (talk) 13:14, 28 May 2023 (UTC)[reply]

The purpose of the Talk page is to discuss proposed and specific changes to the main article, not to seek assistance in teaching about a subject.Sbishop (talk) 13:17, 28 May 2023 (UTC)[reply]

I want to discuss a change to the main article : proponents of cryptos pretend we can reap without having sown. TD (talk) 13:21, 28 May 2023 (UTC)[reply]

You've been warned about WP:NOTAFORUM before. This topic area is under contentious topics restrictions. You must stop using this talk page improperly. MrOllie (talk) 13:27, 28 May 2023 (UTC)[reply]

I read WP:NOTAFORUM. I don't understand why my contribution is against these rules. Please explain. TD (talk) 13:30, 28 May 2023 (UTC)[reply]

You can supplement that with WP:IDIDNTHEARTHAT. It's been explained to you. I'm not going to help you disrupt this talk page even further by doing so again here. MrOllie (talk) 13:33, 28 May 2023 (UTC)[reply]

intro section perhaps unbalanced?[edit]

The introduction doesn't mention a single negative or dubious aspect about cryptocurrencies (abundance of fraud, lack of regulation, criticism by experts, suicides after value loss). Is it ok if I add one or two of these aspects to the body of the first section? Themidget17 (talk) 19:33, 3 June 2023 (UTC)[reply]

Сhange the link to the Tornado Cash[edit]

Coinmarketcap recently updated the link to the Tornado Cash website. Is it possible to do this on the project's Wikipedia page? Vladlen Terezhe (talk) 08:37, 19 June 2023 (UTC)[reply]

Why are you trying to discuss this here? This article does not even mention Tornado Cash. Retimuko (talk) 19:30, 19 June 2023 (UTC)[reply]

Security and Risks in Bitcoin

Bitcoin, like any other digital asset, is not immune to security threats. Understanding the potential vulnerabilities and risks associated with Bitcoin is crucial for users to safeguard their investments and transactions.

1. Potential Vulnerabilities

a. Double Spending: One of the inherent risks in decentralized currencies like Bitcoin is the possibility of double spending, where a user attempts to spend the same bitcoin more than once. This risk is mitigated by the blockchain's consensus mechanism, which validates and timestamps transactions.
b. 51% Attack: A 51% attack occurs when a single entity controls the majority of the network's mining hash rate, enabling them to manipulate transactions, reverse transactions, and potentially double spend bitcoins. While such an attack is theoretically possible, it becomes increasingly difficult as the network grows.
c. Wallet Vulnerabilities: Bitcoin wallets, whether software-based or hardware-based, are susceptible to various security risks such as malware, phishing attacks, and physical theft. Users must employ robust security practices to protect their private keys and ensure the integrity of their wallets.

2. Hacking Incidents

a. Exchange Hacks: Over the years, several cryptocurrency exchanges have fallen victim to hacking incidents, resulting in the loss of millions of dollars worth of bitcoins. These breaches highlight the importance of choosing reputable exchanges with robust security measures in place.
b. Wallet Breaches: Individual users have also experienced wallet breaches due to compromised private keys, insecure storage practices, or vulnerabilities in wallet software. High-profile cases of wallet hacks serve as reminders to prioritize security and adopt best practices for securing private keys.

3. Measures to Enhance Security

a. Cold Storage: Storing bitcoins in cold wallets, which are offline and not connected to the internet, provides an added layer of security against hacking attempts and online threats.
b. Multi-Signature Wallets: Multi-signature wallets require multiple private keys to authorize transactions, reducing the risk of unauthorized access and enhancing security, especially for institutional investors and businesses.
c. Two-Factor Authentication (2FA): Enabling 2FA adds an extra layer of security to Bitcoin wallets and exchange accounts, requiring users to provide a second form of verification, such as a code sent to their mobile device, before accessing their funds.
d. Regular Audits and Penetration Testing: Bitcoin exchanges and wallet providers should conduct regular security audits and penetration testing to identify and address potential vulnerabilities proactively.
e. Education and Awareness: Educating users about security best practices, such as avoiding phishing scams, securing private keys, and verifying the authenticity of wallet software, is essential for fostering a secure Bitcoin ecosystem.
