Bitcoin, the world’s most popular cryptocurrency, has recently stabilized at a value of $62,000. This has resulted in 99% of Bitcoin wallets being in a profitable position. But what does this mean for the future of Bitcoin? What’s the next move? In this article, we will delve into the factors that could influence Bitcoin’s value in the future and provide some predictions based on current trends and data.

Bitcoin’s Current Position

Bitcoin’s recent stabilization at $62,000 is a significant milestone for the cryptocurrency. This value represents a nearly 100% increase from its value at the beginning of 2021. Furthermore, this stabilization has resulted in 99% of Bitcoin wallets being in a profitable position, a testament to the cryptocurrency’s growth and potential.

Factors Influencing Bitcoin’s Value

Several factors could influence Bitcoin’s value in the future. These include:

• Market Demand: As with any commodity, the value of Bitcoin is heavily influenced by supply and demand. If demand for Bitcoin increases, its value is likely to rise. Conversely, if demand decreases, its value could fall.
• Regulatory Environment: Government regulations can also impact Bitcoin’s value. If governments impose stricter regulations on cryptocurrencies, this could potentially decrease demand for Bitcoin and lower its value.
• Technological Developments: Technological advancements in blockchain technology could also influence Bitcoin’s value. For example, improvements in transaction speed and security could increase demand for Bitcoin.

Future Predictions for Bitcoin

Given these factors, what can we expect for the future of Bitcoin? While it’s impossible to predict with certainty, several trends suggest that Bitcoin’s value could continue to rise.

• Increasing Adoption: More and more businesses are beginning to accept Bitcoin as a form of payment, which could increase demand for the cryptocurrency. Additionally, several countries, including El Salvador, have adopted Bitcoin as legal tender, which could further boost its value.
• Continued Technological Advancements: As blockchain technology continues to advance, this could make Bitcoin more appealing to potential users, thereby increasing its value.
• Positive Market Sentiment: The recent stabilization of Bitcoin’s value has resulted in positive market sentiment, which could further drive up its value.

What’s the Next Move?

Given these trends, it seems likely that Bitcoin’s value will continue to rise in the future. However, it’s important to remember that the cryptocurrency market is highly volatile and subject to rapid changes. Therefore, investors should always do their own research and consider their risk tolerance before investing in Bitcoin.

Conclusion

In conclusion, Bitcoin’s recent stabilization at $62,000 and the fact that 99% of Bitcoin wallets are now in a profitable position is a positive sign for the cryptocurrency. Several factors, including increasing adoption, continued technological advancements, and positive market sentiment, suggest that Bitcoin’s value could continue to rise in the future. However, the cryptocurrency market is highly volatile, and investors should always do their own research before investing.

I believe that bitcoin wallets need block filters to respect a user’s privacy. Why? It’s the only way to keep data from leaking to the server, which would allow it to link a user’s transaction data beyond what is publicly available.

In this article, we will explore why bitcoin wallets need block filters by first looking at how many bitcoin users run full nodes, how API wallets offer good user experience but ultimately lead to all your transactions being linked together, how bloom filters have failed to protect privacy, how block filters are the only lightweight wallet network privacy solution, and finally how this can all be implemented using Tor-only communication to also protect a user’s IP address.

Only a Few Users Run Full Nodes

Running and using a Bitcoin node is the best thing you can do because you’re part of the network and you don’t need any intermediaries to receive and broadcast transaction data. However, It’s obvious that running a full node is not for everyone; the existence and need for light clients (Simple Payment Verification) was even envisioned by Satoshi in the Bitcoin whitepaper.

We can’t know how many users are running a full node, we can only know how many nodes there are. Conservative estimates that count only listening nodes would put this number at around 16,000, as seen on the Bitnodes.io site. More accurate estimates that count both listening and non-listening nodes such as Luke Dashjr’s node count tool put this number higher, at around 53,000.

It’s also important to be aware of the historical context of the number of full bitcoin nodes. According to the Bitcoin Node Count History by Luke Dashjr, we can observe that the usage of bitcoin nodes is far from its peak. On January 13, 2018, the count reached 205,000. This was highly related to the fact that bitcoin had reached its previous all-time high a few weeks earlier. In 2021, we can observe that the node count also increased when the price went up, but it only reached close to 90,000.

We can confirm that there are few users running bitcoin nodes, and that this number is not increasing over time. Light wallets are much easier to use than a bitcoin node, and we need to find the right network privacy solution to implement. Let’s take a look at the most used technology today, which is API wallets.

API Wallet Service Providers Collect Your Data by Default

Most bitcoin wallets use APIs (Application Specific Interface) to send and receive user transaction data. This technology is highly scalable and provides the best user experience, as requests are instantaneous. However, it has an inherent privacy caveat. Let’s break down how it works and how service providers collect your data by default.

When you initialize a standard bitcoin wallet, you import or create a mnemonic seed phrase and set the desired derivation path (often automatically). This gives you a master public key, often called an xpub. Here’s what it looks like:

xpub6CUGRUonZSQ4TWtTMmzXdrXDtypWKiKrhko4egpiMZbpiaQL2jkwSB1icqYh2cfDfVxdx4df189oLKnC5fSwqPfgyP3hooxujYzAu3fDVmz

Once that’s done, the xpub is automatically sent to the service provider’s server, where it derives bitcoin addresses within the gap limit (how many unused addresses with a balance of zero will be checked before the server stops scanning for funds). These addresses are looked up in the server’s index, and if transactions are found, they are sent to the user’s client. The addresses are watched in case new transactions occur. In addition, when a user sends a transaction, it’s also sent through the same communication channel.

It’s obvious that this process is very efficient and allows API wallets to provide a fast and easy user experience. However, the service provider will be able to link all of our transactions together, and thus collect your private information by default. Fortunately, many API wallets allow users to connect through Tor, so at least a user’s IP address is protected.

Let’s now examine an alternative method that does not depend on a single server, the use of bloom filters on light wallets.

Why Bloom Filters Don’t Work for Privacy

Some wallets allow a user to receive and send transaction data through Bloom filters. This communication method was introduced in BIP37 and was originally thought to be private. In this section, we’ll break down what Bloom filters are and why they’re actually not good for privacy.

Bloom filters are probabilistic data structures used to test whether an element is a member of a set. In the bitcoin context, bloom filters are created by a light client and sent to network peers, which test whether there’s a match between an address (element) and blockchain data (set). If there’s a match, the transaction data is sent to the light client. It’s probabilistic because there are false positives, but these are later discarded by the light client.

It was thought that the false positive rate would be high enough that a network peer wouldn’t be able to tell which transactions were really yours and which were fake. However, due to an implementation error, the false positive rate was actually reduced.

Additionally, a light client can create different bloom filters for the same wallet, and if two or more are collected by a network peer, the intersection can be calculated to remove false positives. Finally, if blockchain data is analyzed and the user doesn’t coinjoin or use coin control, a network peer can infer which addresses don’t belong to the user.

You can read more about the privacy issues with BIP37 here. Now let’s examine the remaining light client network solution.

A Bitcoin Wallet Needs Block Filters for Privacy

Back in 2018, there was no real solution to this problem, block filters weren’t a thing yet. Fortunately, they were introduced the following year in BIP157 and 158, and are now implemented in several wallets and bitcoin software such as Wasabi, Blixt, Breez, LND, and LDK. They’re often referred to as Neutrino. In this section, we’ll examine how they work and why they’re the right solution for network privacy.

Block filters compress block data to help wallets receive transactions from peers without compromising privacy by downloading specific blocks instead of looking up individual transactions.

The block filter process typically involves three steps. First, a user downloads the block filters representing the blockchain from a network peer in the case of Breez, or from the coordinator server in the case of Wasabi. Then, the light client checks to see if the addresses within the gap limit match a block filter. Finally, if there’s a match, the corresponding block is downloaded.

Because we’re downloading entire blocks instead of individual transactions, and because there’s a false positive rate, the block filter method works to protect a user’s privacy from network peers. Unlike Bloom filters and API wallets, it can’t figure out (or doesn’t collect directly) the connection between a user’s transactions, other than what is publicly known on the blockchain.

Block filters are part of the solution to network privacy, but something else is needed to complete the picture.

Tor is the Last Remaining Piece to Solving Network Privacy

Tor and bitcoin go hand in hand, and together with block filters, can solve network privacy for lightweight clients. Tor hides a user’s IP address from the destination server by routing it through a network of nodes. This mechanism is called onion routing because of the multiple layers of communication.

Tor and block filtering have one thing in common. They’re both processes that can slow down performance, and that can be noticeable and degrade the user experience. Some people think you just have to accept this, but I think it can be improved to the point where it’s barely noticeable.

For example, the Tor community has implemented a communication reliability solution called Conflux. Instead of making a single request, clients make two requests using two different Tor circuits to increase the likelihood of fast completion. This, along with innovations in wallet loading for block filters like Turbosync on the Wasabi wallet, will lead us to a future where a user doesn’t have to choose between usability and privacy, but can enjoy both.

Key Takeaways

• Since the beginning of cryptocurrencies, bitcoin wallets have seen tremendous development.
• Modern systems now provide improved convenience, security, and user-friendly features.
• Users may choose a wallet with more knowledge if they are aware of the evolution of Bitcoin wallets.

Bitcoin Wallet: A Private Digital Safe

Let’s first define a Bitcoin wallet before starting our time travel adventure. A Bitcoin wallet is a software program or physical object that enables users to securely store, transmit, and receive bitcoin. Your private keys, which are necessary for accessing your Bitcoin assets, are stored in it as a virtual vault. It would be nearly difficult to conduct Bitcoin transactions without a wallet.

• Fun fact: Did you know that Satoshi Nakamoto, the enigmatic person who invented Bitcoin, carried out the first transaction? On January 12, 2009, he gave developer Hal Finney 10 bitcoins, thus launching the cryptocurrency.

Paper Wallets and Simple Software Wallets in the Beginning

Security was a major issue in the early days of Bitcoin. To store their private and public keys, users depended on paper wallets, which were simply printouts. The keys were stored offline, away from any online threats, in these paper wallets, making them safe. They were inconvenient, though, because each transaction needed human key input.

• Interesting fact: On May 22, 2010, Laszlo Hanyecz created history by carrying out the first Bitcoin transaction in the real world. He spent 10,000 bitcoins, or millions of dollars in today’s currency, to buy two pizzas.

Basic software wallets soon followed, offering a more user-friendly interface. Users could easily manage their Bitcoin on their PCs with the help of these wallets, which were easy to install. To avoid data loss, they needed to be constantly backed up and were susceptible to virus assaults.

Mobile Wallets: Access to Bitcoin Anywhere

With the popularity of smartphones, Bitcoin wallets appeared on portable electronics, enabling users to carry their digital assets with them wherever they went. Mobile wallets made using Bitcoin more convenient and opened the door for regular transactions.

• Fun fact: In 2013, James Howells, a programmer, mistakenly threw away a hard drive containing his Bitcoin wallet. The hard disk was eventually dumped in a landfill, where it is still today. Over 7,500 bitcoins, worth millions of dollars, are thought to be in the misplaced wallet.

Accessing Bitcoin Anywhere, Anytime with Web Wallets

The ability to access money from any internet-connected device thanks to web wallets transformed the Bitcoin experience. Users no longer had to bother about backups or install software. They may use a web browser to safely access their Bitcoin, making it simpler for beginners to enter the cryptocurrency realm.

• Interesting fact: In 2014, Mt. Gox, previously the biggest Bitcoin exchange, experienced a significant security breach that cost the company around 850,000 bitcoins. The significance of security precautions in safeguarding Bitcoin wallets was brought home by this occurrence.

Hardware Wallets: The Bitcoin Fort Knox

Hardware wallets became the most safe choice as Bitcoin’s value skyrocketed and security worries multiplied. These tangible objects protect private keys from potential internet attacks by storing them offline. Hardware wallets offer an additional degree of security for your Bitcoin by being resistant to hacker attempts.

• Fun fact: By the end of 2020, more than 1.5 million pieces of the Ledger Nano S, one of the most popular hardware wallets, had been sold.

Feature-Rich and User-Friendly Modern 

Bitcoin wallets have become sophisticated, feature-rich solutions in modern times. They provide seamless exchange integration, support for several currencies, biometric identification, and improved user interfaces. Some wallets even let users to engage in decentralized finance (DeFi) systems and earn interest on their Bitcoin holdings.

Conclusion

From its inception to the present, Bitcoin wallets have had an amazing journey. Wallets have improved in security, practicality, and use with each new development. It’s important to keep in mind, though, that in the end, it’s your obligation to protect your Bitcoin. To guarantee the safety of your digital riches, keep educated, follow best practices, and select a wallet that fits your demands. Wallets are incredibly important in the fascinating world of Bitcoin. Your Bitcoin adventure awaits, whether you choose a stylish mobile wallet or the strong security of a hardware wallet.
