Building a Bitcoin wallet is no easy task, but with the right tools and frameworks, developers can build robust and secure wallets that provide a seamless user experience. The use of Flutter, BDK, and other standards and protocols provides a powerful and reliable platform for building Bitcoin wallets.

Your guide to ordinals, lightning minecraft servers, personas, a whole bunch of conferences and bitcoin job opportunities.

What’s the best solution for you? The best solution is the one that fits your personal needs best. Every wallet has different features, as well as up- and downsides. It is on you to figure out your needs and possibilities and then to find the optimal solution for those. Non-custodial Lightning wallets might be a little less convenient to use and come with an initial cost when setting up the channels, but you are in full control over your own funds. You are financially sovereign.

One of the biggest challenges of the Bitcoin network is having a low latency, highly secure and private way of exchanging messages between peers. The censorship resistance requirement of the system is determined by the ability to propagate messages without risk of interception by third parties like ISPs. Implementing solutions that enhance privacy among network participants is one way of ensuring that the censorship resistance requirement is satisfied. In this post, we dive into the need for bitcoin’s transport protocol to encrypt messages exchanged between peers. Since all data relayed in the Bitcoin P2P network is inherently public, and the protocol lacks a notion of cryptographic identities, peers talk to each other over unencrypted and unauthenticated connections. This is a risk to the Bitcoin network’s security in the presence of attackers.

In Bitcoin, a UTXO is considered dust when the fee required to spend it is greater than the amount on the UTXO. Bitcoin Core considers a UTXO as dust if it's value is lower than the cost of spending it at the dustrelayfee. In Bitcoin Core, this dustrelayfee can be set by a commandline argument -dustrelayfee. Additionally, Bitcoin Core default dustrelayfee is 3000 sat/kB. In this article, we explore the bug while trying to open a channel from an LDK node to an LND node. This bug made us explore an important concept in Bitcoin and Lightning called dust limit. We also see how payments under the dust limit don't create HTLC output as transaction with outputs under the dust limit are not viable on-chain as they will not be relayed by nodes.

lnurl-auth is very unique in the sense that it doesn’t even need a Lightning wallet to work, it is a standalone authentication protocol that can work anywhere. The basic idea is that each wallet has a seed, which is a random value (you may think of the BIP39 seed words, for example). Usually from that seed different keys are derived, each of these yielding a Bitcoin address, and also from that same seed may come the keys used to generate and manage Lightning channels. What lnurl-auth does is to generate a new key from that seed, and from that a new key for each service (identified by its domain) you try to authenticate with.

It's great to see Bitcoiners joining Nostr, the decentralized social network. This is a good, short post from ConsentOnChain blog that all Nostriches should read.

Bitcoin mining is currently one of the most competitive and fragmented industries in the world. Our Porter’s Five Forces analysis indicates that the bitcoin mining industry will remain ultra-competitive and fragmented. The industry has exceptionally low barriers to entry, meaning there will be a constant flow of new entrants into the sector. The low barriers to entry are great for decentralization but put pressure on the profit potential of existing players. The ultra-competitive nature of bitcoin mining has two implications. Firstly, the industry will likely stay decentralized, and secondly, only the lowest-cost operators will survive and thrive over the long term.

While bitcoin’s usefulness as a store of value and medium of exchange is becoming more widely appreciated, those choosing to adopt it tend to cluster into stages. These stages are: Learn, Insure, Save, Allocate, Commit, and Endure

“Bitcoin” encompasses two related but distinct concepts. First, individual bitcoins (lowercase b) are units of (fiat) digital currency. Second, the Bitcoin protocol (uppercase B) governs the decentralized network through which thousands of computers across the globe maintain a “public ledger”—known as the blockchain—that keeps a fully transparent record of every authenticated transfer of bitcoins from the moment the system became operational in early 2009. In short, Bitcoin encompasses both (1) an unbacked digital currency and (2) a decentralized online payment system. Whether Bitcoin becomes a bona fide money is still an open empirical question, but at this point—since Bitcoin is already a medium of exchange—Mises’s regression theorem doesn’t have any bearing on the outcome.​

Nostr is for developers. It’s an open-source project for builders that serves as a broadcast platform and content hub aggregate. From the architecture alone, we can start to differentiate it from Twitter or any other existing platform. This protocol is newly, actively developed — so while it tugs at the root of topics like free speech and privacy, the tech itself is in its nascent stages. Nostr aims to decentralize private communications and data while allowing us to interact in new ways. For all of those reasons, we should learn about it — perhaps in the same way some of us should have learned about Meta products before dishing our credentials.

A perspective of Bitcoin being an artificial life form.

On one side of this, a sharp and persistent increase in the broad money supply is the biggest quantifiable correlate with price inflation. On the other side, sharp changes in the supply of goods and services (e.g. a major boom or a major loss in productive capacity) also significantly affect price inflation. We can see this with long-term charts of several different developed countries as examples. These charts show the five-year rolling cumulative amount of broad money supply growth and consumer price index growth. Areas where money supply growth greatly exceeded changes to consumer price index were generally due to some sort of productivity boom. combination of high debt, high interest rates on that debt, aging demographics, geopolitical tensions, and tight energy supplies are likely to result in ongoing waves of inflation. For periods where we generally get inflation under control, it will likely be due to global demand suppression and economic stagnation, rather than what we actually want: global disinflationary growth.

Greg Foss thinks Bitcoin should be considered default insurance on the entire global fiat currency system—like a CDS on the US dollar, Canadian dollar, British pound, euro, yen, yuan, and all the rest of the government currencies. Some proponents believe the endgame for Bitcoin is to eventually emerge as the world’s dominant form of money. It’s a process called “hyperbitcoinization”—or what I like to call The Bitcoin Supremacy. That’s why Bitcoin is even better than a CDS. It provides insurance against the failure of the entire worldwide fiat currency system, has no counterparty risk, and doesn’t expire.

Would the collapse (in terms of redemptions) of a stablecoin cause contagion in the traditional financial system? To answer this, first we have to clarify the starting point, and then there is actual data that can answer many of these questions.

history of debt in bitcoin mining, examined key principles of debt, and looked at some of the most common structures available to bitcoin miners. Now that we understand the landscape, we will take a look at the considerations for borrower and lender alike, the effect of leverage on mining returns, and discuss how the future of the market might look. Here are the main topics covered in Part 2: ‍Key considerations from a lender's point of view and from miners' point of view, a case study, comments on the future of debt in Bitcoin mining, shortcomings of ASIC-backed debt, cost of capital being king, and The Forever Forthcoming Hash Rate Marketplace.

Computation is competition. While the quantum computing threat is not something we expect to be worth worrying about for many years, it is better to be proactive rather than wait for it to come for us. Security is the science of staying ahead. The very act of wealth preservation is comprised of staving off the many attempts to steal it.

Between 2009 and the end of 2021, household sector wealth soared by 150%, increasing from $60 trillion to $150 trillion. The index, which is commonly referred to as the Wealth-to-Income Ratio, has a 68-year average is 550%. Its interesting to observe how the index behaved in the face of past examples of record high stock prices. “Actual” inflation is likely much higher than the official number. According to Shadow Government Statistics, if inflation were calculated in the manner that it was back in 1990, we would have an “official” inflation rate of more than 17%. What will the Fed and the government do now? This time, it is unlikely that the government will step in to save investors. Additional fiscal stimulus would likely drive inflation even higher. And in the face of high inflation, the Fed’s response is money destruction, not money creation. Investors, therefore, are in a very tough place.

Over the past 10+ years, there has been a growing movement of people adopting a low-time-preference strategy of saving and investing with the goal of achieving financial independence early in life, putting themselves in a position to retire earlier than the traditional age of 65. Hence the acronym, FIRE: Financial Independence, Retire Early. Bitcoin allows you to mitigate the certainty of dollar debasement without exposing yourself to the risks of investing. A deep dive into the bitcoin rabbit hole tends to lead to the conclusion that its adoption will continue apace, leading to its value rising exponentially. Bitcoin represents the greatest asymmetric bet the world has ever seen.

The U.S. Federal Reserve is now operating at a financial loss, and is months away from having negative tangible equity for the first time in modern history. This article explores how we got here and to what extent any of this matters for savers and investors. The Federal Reserve’s soon-to-be negative tangible net equity won’t matter at first, and for most people won’t even be noticed. However, over the long-term, this is actually somewhat relevant. By the end of this decade, I have considerable concerns regarding a fiscal spiral occurring in the United States and other developed countries, meaning that a combination of high deficits, high debts, and high interest rates on those debts, will all work together to create structural inflation and money supply growth.

The longstanding compromise on transaction sizes, how Taproot and SegWit inadvertantly blew it up, and the nascent NFT protocol emerging in its wake.

Abstract: In this piece we explore why Dapps are typically built on Ethereum rather than Bitcoin, which takes us all the way back to March 2014. We examine a debate about whether and how a Dapp protocol called Counterparty should use Bitcoin’s blockchain. This was sometimes called “The OP_Return Wars”. We explain the history of OP_Return usage and sidechains in Bitcoin. We conclude by arguing, whether one likes it or not, that it was the culture in the Bitcoin development community in 2014 and the negative view of using Bitcoin transaction data for alternative use cases, which played a major role in pushing developers of these Dapps onto alternative systems like Ethereum, along with other factors.

Keep learning about money, technology, economics, and all the problems Bitcoin was designed to solve. The more you understand and appreciate bitcoin, the closer you come to making a splash of your own.

The US debt ceiling is in the news again due to Congressional gridlock, along with the possibility of a US sovereign default and the unintuitive idea of the US Treasury Department minting a trillion-dollar platinum coin to bypass the problem. This article breaks down some of the nuances involved in this strange situation, which comes up every few years.

We Bitcoiners are in a race. Perhaps the most important race we will ever run. We are racing against time to drive the adoption of Bitcoin as fast as we can. We are racing toward a future in which the U.S. Government never coordinates a concerted attack against Bitcoin and Bitcoiners. This is a race to avoid a war. Although Bitcoin is destined to win, if we lose the race to avoid the war, victory will be far more costly. This would be the long way — and the hard way. Instead of a sprint to a bright, orange future, we would be embroiled in a long, hard confrontation with a government desperate to hold on to the power of the monetary printing press. If we lose the race, the long, hard path will be a war in which hundreds of millions of people will suffer the decivilizing and impoverishing effects of hyperinflation. So, for those of us alive, for those of us ready and able now, it is vitally important to run this race as well as possible.

This article explores technical analysis of mining behavior exhibited by an entity that is plausibly Satoshi Nakamoto. The major conclusions are: - Their goal was to keep the "heartbeat" of the network alive while it was being bootstrapped. - They mined on a single machine with a maximum hashrate of 6 Mhps. - They could have easily earned more than twice as much BTC if they had mined at full power. - They did not want to be in a position of dominating the network hashrate, but may have felt it was necessary during the earliest days when the network was far more fragile due to having fewer than five miners. - They cared a great deal about difficulty adjustments. The adjustment algorithm was one of Satoshi's greatest innovations and they opined upon the topic more than almost any other. - They wanted as many people to be able to mine on home PCs as possible (Satoshi decried the FGPA / GPU mining race)

Exasperated with a conversation, I asked my friend directly, "What do you think the probability is that Bitcoin hits $1M per coin?" My friend replied without hesitation, "0.001%." I laughed and said I put it at 80%. We had a conversation about my friend's skepticism, and I wondered if there was some information asymmetry, or if it was self-motivated beliefs. My friend group is full of people like this, highly intelligent and successful, yet resistant to Bitcoin. I've found it to be a topic of fascinated frustration. I believe that my friends are resistant to Bitcoin because of their trust in the current system, and see Bitcoin as a radical departure from it. In contrast, I see Bitcoin as a necessary response to the flaws in the current system and a trust-minimized store of value.

Many speculate that Bitcoin’s security will lapse with the end of the mining subsidy. But other factors will continue to incentivize miners. Two prominent and likely factors are: (1) Higher transaction fees due to base layer settlement activity for higher layers which in turn is the result of increased adoption and (2) Bitcoin miners can act as an auxiliary tool for other business practices, an example being the highly-overlooked development in the mainstream involving the Bitcoin miners’ incentive to pursue stranded, wasted or excess energy.

Bitcoin provides the ultimate form of transferable value because it preserves the encapsulated wealth. This is an opinion editorial by Leon Wankum, one of the first financial economics students to write a thesis about Bitcoin in 2015.

After years of learning, I now devote a fair amount of my time trying to help others understand bitcoin better. While many people have referred to me as a “bitcoin expert,” I still consider myself a student – I have yet to determine how deep the rabbit hole goes.
