The Fed Has Pumped $500 Billion Into the Repo Market. Where Does It End?

In September 2019, the interest rate for the overnight money market — a short-term lending market where banks borrow cash from each other to meet reserve requirements at the end of a business day — surged to 10 percent. Banks weren’t willing to lend out capital for the Federal Reserve’s target interest rate of 2 percent. The Fed responded to the cash crunch by financing these so-called repurchasing agreements (repos, for short) directly. It offered the 2 percent interest on these short-term loans (they’re usually paid back in days or…

Video: Reviewing the Billfodl Multishard

Bitcoin Magazine reviewed the Billfodl Multishard, a two-of-three stainless steel recovery seed storage device that allows you to split your seed into three shards, ensuring that, even if someone finds one part of your phrase, they won’t be able to steal your funds.

Shard One houses words 1 to 16, Shard Two houses words 9 to 24 and Shard 3…

Review: HTC Exodus 1s, the Full Bitcoin Node Smartphone

When it launched during The Lightning Conference in October 2019, HTC’s Exodus 1s smartphone took on the ambitious mission of endowing Bitcoiners with a device that delivers the security of a hardware wallet and the privacy and sovereignty of a full Bitcoin node.  At a retail price of 219 euro (approximately $245), plus shipping tax, the device is more affordable than a Casa Node and half as expensive as a Ledger Nano X hardware wallet. Weighing less than 6 ounces and sporting a shiny 5.7-inch screen, the HTC Exodus 1s…

The Kindest Cut: Why the 2020 Bitcoin Halvening Is the Most Important Yet

In May of 2020, bitcoin will see its next halving: the reduction of the reward for successfully mining a block. The Nakamoto white paper specifies that every 210,000 blocks, the reward for successfully mining a block is cut by half. But while these occur roughly every four years (with the estimated reward dropping to one Satoshi on or around the year 2140), the Bitcoin Halvening of 2020 is particularly momentous. At present, the reward for mining a block is 12.5 BTC; in May, the reward for successfully adding a block…

Bitcoin Researcher Drums Up Academic Interest in Erlay Protocol

In November 2019, Gleb Naumenko, co-author of the Erlay protocol and Bitcoin researcher at Chaincode Labs, came to London to present at the ACM conference 2019.  The ACM conference is one of the premier conferences on computer and communications security. It brings together “security researchers, practitioners, developers and users from all over the world.” Naumenko’s appearance was a rare recent example of Bitcoin research being covered at a conference focused on broader topics than exclusively cryptocurrency (or “blockchain”).  As Naumenko himself has said, there are numerous benefits to getting individuals…

Do CoinJoins Really Require Equal Transaction Amounts for Privacy? Part One: CashFusion

Although Satoshi Nakamoto’s white paper suggests that privacy was a design goal of the Bitcoin protocol, blockchain analysis can often break users’ privacy. This is a problem. Bitcoin users might not necessarily want the world to know where they spend their money, what they earn or how much they own, while businesses may not want to leak transaction details to competitors — to name some examples. But there are solutions to regain privacy, like CoinJoin. Some of the most popular mixing solutions available today use this trick, including Wasabi Wallet…

Wasabi Wallet Launches #BitcoinIsSafe Campaign to Counter Erroneous Antivirus Detections

Recently, Wasabi Wallet users have reported multiple instances in which antivirus programs identify both Wasabi and the newly integrated Bitcoin Core as “system infections.” More specifically, the computer security algorithms for Avira, Bitdefender, Kaspersky and F-Secure (and many other antivirus softwares) confuse full Bitcoin nodes with unwanted cryptocurrency mining programs that run in computer backgrounds and steal processing power (a type of malicious attack whose popularity peaked during the 2017 bull market). In response to this phenomenon, Wasabi Wallet developers have started a social media campaign — distinguished by the…

On the Coast of El Salvador, Bitcoin Is Becoming the Standard

When Michael Peterson made a semi-permanent move to El Salvador, the California native’s motive was simple and, well, fittingly expected: He wanted a place to surf in the wintertime.  “I came to El Salvador on a surf trip and I just kind of fell in love,” he explained. “The water’s warm, the waves are great, the people are super friendly. So my wife and I decided to buy a house and move there — that was 14 years ago.” Now, in a less-than-expected twist, Peterson is working on bootstrapping bitcoin…

Want to Learn About Bitcoin? Try Conference-Driven Development

Continuing our series on how to learn about Bitcoin and its more technical aspects, in this article, we will focus on presenting at conferences and meetups as a means to this end. On the Ladybug podcast, Ali Spittel coined the term “conference-driven development.” Aspiring Bitcoin savants can pursue this sort of development by taking on the responsibility of presenting at a conference on a subject matter that lies outside their current area of expertise.  The Ladybug podcast hosts discussed their experiences with “conference-driven development” preparing and delivering presentations on as…
