Discover Damus: The Future of Decentralized Social Media

Social media has transformed dramatically over the last decade, with platforms continually evolving to suit the ever-changing user preferences. Amid this changing landscape, a new player has emerged: Damus. This unique social networking platform is built on the Nostr open protocol – a system standing for “Notes and Other Stuff Transmitted by Relays.” Today, we delve deeper into Damus, exploring its key features, its challenges, and the future that lies ahead for this innovative platform.

The Unique Features of Damus

One of the most defining characteristics of Damus is its Uncensored Nature. Built on the Nostr protocol, Damus is free from the control of any central authority. There are no platforms or entities that can censor or restrict it, offering users a breath of fresh air in terms of control over their data and posts. This uncensored nature makes Damus a platform that’s resilient to censorship.

Moreover, the platform offers a user-friendly experience with No Personal Information Needed for account creation. Contrary to most social media platforms requiring personal details such as names, email addresses, and phone numbers, Damus operates differently. Users are provided a “private key” and “public key” for managing their accounts. However, this convenience comes with a downside – account recovery can become tricky if you lose or forget your keys.

In a unique move, Damus plans to introduce a Bitcoin Tipping feature. This function, although not implemented yet, will enable users to tip each other in Bitcoin for posts and other interactions.

Damus also shares a Similarity with Twitter. You can customize your avatar and background image, input profile information, and enjoy similar functionalities as Twitter offers. Troublesome users can be blocked or reported, ensuring a safer environment for interaction.

Points of Caution with Damus

Every platform has its hurdles, and Damus is no exception. Account Management can be a challenge due to the absence of linked email addresses, which makes password recovery difficult. Users are advised to handle their account keys with extra caution to prevent any inconveniences.

Also, the platform is currently limited in its language options, not yet offering Japanese language compatibility or options to change the default language. This limitation could pose a barrier for non-English speakers.

While Damus shares similarities with Twitter, it is important to note that as a new platform, it does not yet match Twitter in terms of functionality. Issues like inability to delete posts in the smartphone version, difficulties with image posting, and the lack of specific content search capabilities are areas for improvement.

Recent Developments and Future of Damus

Recently, Damus was banned in China and removed from the Chinese App Store, as per a tweet from Damus. The Chinese Cyber ​​Space Management Bureau (CAC) cited the reason as the platform’s potential to form public opinion or social mobilization.

Looking ahead, Damus’s potential is significant. As more people grow concerned about incidents such as sudden mass account suspensions on Twitter and the paid API, there’s a growing trend of users Switching from Twitter to Damus.

Damus might be in its nascent stages and not yet at par with Twitter, but its unique features and the promise of a censorship-resistant platform make it stand out. Future expansions and improvements, particularly the Bitcoin tipping function, are expected to attract more users to Damus, potentially changing the landscape of social media platforms.

In a world where control over personal data and freedom of expression are increasingly important, Damus might just be the breath of fresh air that the social media world needs. Only time will tell how this promising platform continues to evolve and disrupt the social networking space.

How Cashfusion works

CashFusion is a privacy protocol that allows anyone to create multiparty transactions with other network participants. It obfuscates the actual payments of users, making it difficult for chain analysis companies to track their coins. Below is an explanation of how CashFusion works:

  1. CashFusion is integrated into the Electron Cash wallet and is available for use on Windows, Mac OSX, and Linux.
  2. When CashFusion is activated, the wallet begins to communicate with other wallets that have CashFusion enabled.
  3. CashFusion sends the user’s funds through jumbo-sized transactions and back to their wallet.
  4. The user’s wallet participates in transactions with numerous inputs and outputs provided by many other CashFusion participants.
  5. Because the number of possible combinations of inputs and outputs is astronomically large, it is basically impossible for anyone to know who owns which inputs and outputs.
  6. After the user’s coins have gone through one or more fusion transactions, they can be used freely.

CashFusion differs from traditional coin mixing in that it places a user’s coins in a single large transaction full of other CashFusion users, rather than mixing transactions with others. This makes it more secure and private than traditional coin mixing protocols.

Understanding Privacy Protocols: Comparing Bitcoin Cash’s Cashfusion and Litecoin’s MWEB

In the world of cryptocurrencies, privacy and ease of use are two fundamental aspects that make one solution stand out over another. Among the multitude of privacy protocols, two significant ones are Cashfusion for Bitcoin Cash and the Mimblewimble Extension Block (MWEB) for Litecoin.

This article compares these two privacy solutions, highlighting the reasons why Cashfusion may be considered easier to use due to its no-requirement of downloading the entire blockchain, as opposed to using Litecoin Core with MWEB.

A Brief Introduction to Cashfusion and Litecoin’s MWEB


Cashfusion is a protocol developed for Bitcoin Cash (BCH) that enhances transactional privacy. Unlike traditional Bitcoin transactions, where the origins and destinations of coins are traceable, Cashfusion mixes inputs and outputs of transactions from different users, making it nearly impossible to trace a coin’s movement.

Mimblewimble Extension Block (MWEB)

MWEB is a protocol implemented on Litecoin that increases the privacy and fungibility of transactions. Named after a spell from the Harry Potter series, Mimblewimble provides robust privacy features by obscuring the amounts and destinations in transactions. MWEB transactions are kept separate from the main Litecoin chain, creating an ‘extension block’ that enhances privacy without disrupting the core Litecoin network.

Downloading the Entire Blockchain: An Issue?

A significant factor in evaluating the ease of use between these two privacy solutions is their respective requirements concerning blockchain data.

To interact with MWEB, users typically need to download and synchronize the entire Litecoin blockchain via the Litecoin Core software. This process can be data-intensive and time-consuming, depending on the user’s internet connection and the size of the blockchain at any given time. This requirement may prove to be a hurdle for those with limited storage capabilities or slow internet connections.

On the other hand, Cashfusion doesn’t require users to download the entire Bitcoin Cash blockchain. Instead, users only need a compatible wallet (like Electron Cash) to start transacting privately. The absence of such a requirement means that users can start utilizing Cashfusion faster and easier, without the need to worry about storage space or internet speed.

Accessibility and Ease of Use: Cashfusion versus MWEB

When considering the ease of use between the two, one could argue that Cashfusion has the edge due to its lightweight nature.

To use Cashfusion, you need to download a compatible wallet, set it up, fund it with BCH, and enable Cashfusion. This process can be completed within minutes. From there, the wallet automatically fuses transactions with others, maintaining the user’s privacy without any extra effort on their part. This level of simplicity is a significant advantage for those looking for quick and convenient privacy solutions.

In contrast, using MWEB via Litecoin Core requires more steps. Users need to download Litecoin Core, synchronize the entire Litecoin blockchain, create a new MWEB address, and then conduct transactions. While the privacy benefits of MWEB are considerable, the added complexities and the time required to set it up could be seen as a disadvantage when compared to Cashfusion.

In Summary

While both Cashfusion and MWEB offer robust privacy features for their respective cryptocurrencies, it seems that Cashfusion might have an edge concerning ease of use and accessibility. The no-need to download the entire blockchain for using Cashfusion means a quicker setup and fewer resources consumed, which could be an attractive feature for many users.

However, it’s essential to note that both protocols have their unique strengths and weaknesses. The choice between the two largely depends on the specific needs and resources of the user. As the world of cryptocurrencies continues to evolve, we can expect further improvements and innovations in privacy protocols, enhancing both their usability and security.

What is Needed to Promote Adoption of Bitcoin’s Lightning Network?

The Lightning Network of Bitcoin is expected to be an innovative solution to improve scalability and transaction speed. However, making the Lightning Network accessible to the general users still presents challenges. This article explores why using the Lightning Network is difficult and what is needed to onboard more users.

Difficulties in using the Lightning Network: While the Lightning Network holds promise in addressing Bitcoin’s scalability issues, there are several challenges associated with its usage.

a. Need for custodial wallets: To utilize the Lightning Network, users need to use custodial wallets. This means users have to rely on third parties to manage their Bitcoin instead of managing it themselves.

b. Difficulty in running nodes: Using self-custodial wallets in the Lightning Network requires running a node called lndhub. However, running a node is difficult for the average user and can be seen as a high technical barrier.

Ideas to promote Lightning Network adoption: To facilitate the adoption of the Lightning Network and attract more users, the following ideas can be considered:

a. Simplification of nodes: There is a need to simplify the process of running Lightning Network nodes. Tools and interfaces should be provided that allow users to easily run nodes without requiring technical expertise.

b. User education and outreach: It is important to educate users about how to use and benefit from the Lightning Network. Additionally, outreach activities and awareness campaigns should be conducted to convey the appeal of the Lightning Network to the general user.

Addressing Bitcoin scalability and sustainability: Bitcoin scalability and sustainability are important challenges. While the Lightning Network is part of the solution, there are other approaches such as increasing block size or developing alternative Layer 2 solutions. I believe developers should continue working on Bitcoin scalability and sustainability.


The Lightning Network holds promise as a technology to address Bitcoin’s scalability issues, but the difficulties in its usage hinder widespread adoption. To promote the adoption of the Lightning Network, more user-friendly wallets and simplified node execution procedures are necessary. User education and outreach activities are also crucial elements.

Bitcoin scalability and sustainability should continue to be addressed, and by overcoming these challenges, it will be possible to onboard more users.

Concerns over Ledger Recover

There are several concerns about the Ledger Recover service. Let me list the main points:

  1. Centralization and Trust: There are concerns about the centralization of the recovery process. It’s questionable whether the security of the three entities holding fragments of the recovery phrase (Ledger, Coincover, and Escrow Tech) is reliable. Moreover, the security of the ID authentication process and the storage of personal data on Ledger’s servers could also be problematic.
  2. Potential for Collusion or Hacking: If any two of the three entities are hacked or collude, they could recreate the recovery phrase and potentially gain access to the user’s cryptocurrency. Additionally, there’s a risk that Ledger’s servers could be compromised, which could allow unauthorized access to users’ recovery accounts.
  3. Government Coercion: There’s a potential for government coercion. Ledger might be forced to disclose user information due to laws and regulations.
  4. Security of Personal Data: There are concerns about the safety of personal data, especially IDs and selfies, stored on Ledger’s servers during the process.
  5. User Responsibility: Even when using Ledger Recover, users are required to keep a copy of their recovery phrase. This can also be lost, or not properly managed.
  6. Availability and Convenience: While the Ledger Recover service is only available on mobile apps, firmware updates needed for Ledger Recover can only be done on desktops, which could pose a problem.

In conclusion, I am personally skeptical about the Ledger Recover service given these issues. It seems to move away from the importance of self-management and the principle of cryptocurrency to control one’s own assets. Therefore, I can’t endorse the Ledger Recover service in its current form.

How to get started with crypto without a centralized exchange (CEX)

Starting cryptocurrency without using centralized exchanges (CEX) can be a bit complicated, but here are some options:

Decentralized Exchanges (DEXs): Unlike CEXs, DEXs do not hold your funds. You manage the private keys. Examples include Uniswap, Sushiswap, PancakeSwap. These platforms often utilize smart contracts to facilitate and automate the trading process. However, these services usually require you to already possess some form of cryptocurrency, so they might not solve the initial problem of converting fiat currency into cryptocurrency, but they do serve as an important tool when avoiding CEXs.

Peer-to-Peer (P2P) Trading: This involves buying directly from someone who already owns cryptocurrency. However, you must be cautious of possible scams. Always transact with a party you trust. Platforms like Bisq, LocalCoinSwap, HODL HODL, Remitano, and Noones are examples.

Bitcoin ATM: Bitcoin ATMs function like regular ATMs but allow you to purchase (and sometimes sell) Bitcoin. Some ATMs might also allow the purchase of other cryptocurrencies. You insert cash or a credit/debit card, and the ATM sends cryptocurrency to your wallet. However, these ATMs often carry high transaction fees.

Earning Cryptocurrency: Another approach is to earn cryptocurrency directly. Especially if you work in the technology or crypto industry, some companies pay salaries in Bitcoin or other cryptocurrencies. Additionally, there are platforms where you can earn cryptocurrency by performing tasks, providing services, or participating in surveys.

Cryptocurrency Cards: Some companies offer cryptocurrency cards. These allow you to load fiat currency and convert it into cryptocurrency. While this process might involve a CEX indirectly, you don’t interact with the exchange directly.

Mining: If you have the technical know-how and resources, you can mine certain cryptocurrencies. This requires a significant initial investment in computing hardware and power. While Bitcoin mining is currently very resource-intensive and primarily done by large mining pools, other cryptocurrencies can be mined by individuals.

Faucets: Faucets are sites that offer a small amount of cryptocurrency for free in return for completing simple tasks or solving captchas. This is a slow way of accumulating cryptocurrency and usually requires a fair amount of effort, but it is an option.

Before starting with cryptocurrency, it’s important to do your own research and understand the risks involved. Cryptocurrency values can fluctuate significantly, and investment can lead to significant financial loss.

Ledger Recover will actually promote the mass adoption of cryptocurrencies.

Ledger is widely recognized as a leader in the field of cryptocurrency hardware wallets. Its products, which allow users to securely store their cryptocurrencies, are highly valued by customers worldwide. However, the company’s recently announced new service, “Ledger Recover,” might risk losing some of its existing customers. Nevertheless, I argue that this risk is part of the effort to attract newcomers to cryptocurrencies, thereby promoting their widespread adoption.

Ledger Recover is a unique service that splits and encrypts a user’s recovery phrase into three parts, each of which is stored with a third party such as Ledger. This means that even if a user loses or forgets their recovery phrase, they can still access their assets.

However, this new service is viewed skeptically by veteran cryptocurrency users. They quote the principle of cryptocurrency, “Not your keys, not your coin,” and are apprehensive about entrusting their recovery phrase to a third party. Such concerns are natural, given that Ledger’s responsibility to maintain the security of the information it holds is greatly increased. These concerns might lead some existing customers to leave Ledger.

However, Ledger Recover could potentially be an attractive service for cryptocurrency beginners. Newcomers can venture into the world of cryptocurrencies without the fear of losing their assets. Moreover, Ledger Recover provides an opportunity for beginners to take their time learning about cryptocurrency security. This makes the world of cryptocurrency more friendly and accessible.

Viewed in this light, Ledger Recover has the potential to bring fresh air to the cryptocurrency industry. It may result in the loss of some existing customers, but this is part of attracting new users and promoting the widespread adoption of cryptocurrencies.

From this perspective, Ledger Recover can play a role in promoting the “mass adoption” of cryptocurrencies. Creating an environment where beginners can join with peace of mind is a crucial step towards increasing the popularity and recognition of cryptocurrencies. If realized, it can be a powerful driving force for the growth of the entire cryptocurrency industry.

Therefore, while Ledger Recover may seem bad on the surface, it can be argued that it is actually good when looked at from a larger perspective. It’s a step towards promoting the widespread adoption of cryptocurrencies, and it’s worth taking the risk of losing some existing customers for that. This can be seen as a bold move to pioneer new markets and shape the future of cryptocurrencies.

Are Polygon zkEVM and regular Polygon chains different chains?

Polygon zkEVM and the regular Polygon (formerly known as Matic Network) are different chains from a technical perspective.

The regular Polygon functions as a sidechain to Ethereum, using a Proof of Stake (PoS) consensus algorithm and Plasma chains. This design improves transaction speed compared to Ethereum’s mainnet and significantly reduces fees. However, it’s not entirely equivalent to Ethereum’s mainnet.

On the other hand, Polygon zkEVM is a zero-knowledge scaling solution fully equivalent to Ethereum. It is equivalent to the Ethereum Virtual Machine (EVM), and most existing smart contracts, developer tools, and wallets work seamlessly. The zkEVM uses zero-knowledge proofs (ZK proofs) to reduce transaction costs and significantly increase throughput.

Therefore, these are different chains with different characteristics and functionalities.

Hardware Wallet Security Issues: The Importance of Open Source Firmware

Cryptocurrency hardware wallets are often seen as one of the safest ways to store your assets at first glance. However, the security of these wallets heavily depends on a fundamental aspect: their firmware. I will quote the words spoken by Ledger, a leading company in the hardware wallet industry:

Technically speaking it is and always has been possible to write firmware that facilitates key extraction. You have always trusted Ledger not to deploy such firmware whether you knew it or not.

This statement highlights that the safety of hardware wallets heavily depends on how the firmware is designed and distributed. It also suggests that users need to trust the manufacturer of the hardware wallet.

This is where the importance of open source comes into play. Open source software is a type of software whose code is made public, and can be viewed and verified by anyone. This allows for the verification of the software’s safety. Therefore, hardware wallets with open source firmware offer increased transparency in terms of their security.

However, hardware wallets with non-open source firmware depend on their manufacturer for their security. You have no choice but to trust that the manufacturer will provide safe firmware. As a result, users of these products are forced to believe that the manufacturer will not distribute firmware that makes key extraction easy.

I would like to mention the security risks associated with making firmware open source. In the case of open source, the code is public, so malicious users could potentially find vulnerabilities in the software and attack it. However, it’s also worth noting that members of the community might spot these vulnerabilities and correct them, so this isn’t necessarily a negative.

In conclusion, the safety of hardware wallets heavily depends on the design and distribution method of its firmware. Also, by using open source firmware, the security may be enhanced. However, wallets with non-open source firmware need caution as their security depends on the manufacturer.

Storing cryptocurrency is about finding a balance between security and convenience. Hardware wallets provide convenience, but their security isn’t fully guaranteed. Therefore, when using a hardware wallet, it is crucial to thoroughly consider the reliability of the manufacturer and the security design of the firmware. If possible, choosing a wallet with open source firmware (like Trezor, for example) could provide higher transparency and security.

Moving forward, the security of cryptocurrency hardware wallets will likely become an increasingly important issue for user trust and peace of mind. Manufacturers should strive to improve transparency and security. Users need to understand these facts and make the right choices in order to safely store their digital assets.

Ad-Blocking War: The Brave Browser and YouTube’s Persistent Conflict

Since the widespread use of the internet, web browsers and advertisements have always coexisted. While users search for information online and explore entertainment, advertisements have become an essential tool for business and marketing. However, these ads can hinder the user experience, particularly those on the video sharing platform YouTube, which are often targeted. As a result, some browsers have provided features to block these ads, among which, Brave Browser has courageously tackled this issue, as the name suggests.

Brave Browser’s main feature is to block the potential ads that its users may encounter while searching for information online and browsing content. Particularly for YouTube ads, Brave blocks them, allowing users to watch videos uninterrupted. However, this not only enhances user convenience but could also pose significant problems for content creators and platforms that rely on ad revenue.

On the other hand, YouTube has been changing its specifications to ensure that its ads can be displayed even in Brave. This change aims to ensure that YouTube ads reach users and secure advertising revenue. However, this can be a nuisance for some users, making them feel the need to block ads again.

Thus, what is happening between Brave and YouTube can be described as a cat-and-mouse game. One side blocks ads, the other finds a way to circumvent it, and then the former develops a new way to block. This cycle continues, reflecting the ongoing battle between user experience and ad revenue.

Brave Browser blocks ads and other online trackers by default. This feature, which other browsers do not offer, protects privacy and also speeds up the browsing experience by reducing site loading times. However, there have been reports that ads can still appear on YouTube, even with the latest version of Brave.

This is believed to be the result of YouTube finding and implementing new ways to display ads, and Brave will likely develop new ad-blocking features to address this. This is indeed a repeated cat-and-mouse game, an eternal battle seeking balance between user experience and ad revenue.

In conclusion, such cat-and-mouse games demonstrate the complex relationship between advertising and user experience. Ads are a vital source of income for businesses, but can also be an annoyance for users. Striking this balance is a challenging task, and the fight between YouTube and Brave embodies it. It is crucial to watch how this battle unfolds and what impact it has on both user experience and business revenue.
