Best Bitcoin wallet: Hardware or hosted?

Posted by in categories: bitcoin, cryptocurrencies
The question asked in the title has been edited from what was asked today at Quora, the Q&A forum at which I participate as expert columnist. The original question was a bit more ambiguous: “Which is better? — a digital bitcoin wallet or a physical one?” I have included the original question, to better distinguish products and terms. All bitcoin wallets are all digital—even a paper wallet, whether a character string or a QR code. Conversely, an exchange may use “physical” wallets to host client assets, individual application wallets, or they may simply keep records of client assets that are stored, collectively, in their own master wallet. To complicate matters, Bitcoin is never really “stored” by you or an exchange service. It is stored on a public blockchain, where assets and transaction history can be traced through time by anyone. Therefore, all forms of user access are “digital”. What the reader really wants to know is “Which form of access control is better? — custodial or personal?” Type 1: Custodial Wallets are Managed by a Trusted Party They hold your assets. You view a statement balance—just like a bank account.

How developments in Quantum Computing could affect cryptocurrencies

Posted by in categories: bitcoin, computing, cryptocurrencies, economics, mathematics, particle physics, quantum physics

by Eloisa Marchesoni

Today, I will talk about the recent creation of really intelligent machines, able to solve difficult problems, to recreate the creativity and versatility of the human mind, machines not only able to excel in a single activity but to abstract general information and find solutions that are unthinkable for us. I will not talk about blockchain, but about another revolution (less economic and more mathematical), which is all about computing: quantum computers.

Quantum computing is not really new, as we have been talking about it for a couple of decades already, but we are just now witnessing the transition from theory to realization of such technology. Quantum computers were first theorized at the beginning of the 1980s, but only in the last few years, thanks to the commitment of companies like Google and IBM, a strong impulse has been pushing the development of these machines. The quantum computer is able to use quantum particles (imagine them to be like electrons or photons) to process information. The particles act as positive or negative (i., the 0 and the 1 that we are used to see in traditional computer science) alternatively or at the same time, thus generating quantum information bits called “qubits”, which can have value either 0 or 1 or a quantum superposition of 0 and 1.

Quantum computers put blockchain security at risk

Posted by in categories: bitcoin, computing, cryptocurrencies, encryption, finance, government, health, internet, quantum physics, security

The longer-term answer is to develop and scale up the quantum communication network and, subsequently, the quantum internet. This will take major investments from governments. However, countries will benefit from the greater security offered13. For example, Canada keeps its census data secret for 92 years, a term that only quantum cryptography can assure. Government agencies could use quantum-secured blockchain platforms to protect citizens’ personal financial and health data. Countries leading major research efforts in quantum technologies, such as China, the United States and members of the European Union, will be among the early adopters. They should invest immediately in research. Blockchains should be a case study for Europe’s Quantum Key Distribution Testbed programme, for example.


Bitcoin and other cryptocurrencies will founder unless they integrate quantum technologies, warn Aleksey K. Fedorov, Evgeniy O. Kiktenko and Alexander I. Lvovsky.

When the Fork Forks: What You Need to Know as Bitcoin Cash Goes to War

Posted by in categories: bitcoin, cryptocurrencies

Bitcoin seems largely a ‘psychological’ currency whose value oscillates mostly in response to changes in folk’s opinions rather than shifts in some real underlying store of value, imo https://bitcoinmagazine.com/articles/when-fork-forks-what-yo…-goes-war/ https://paper.li/e-1437691924


Here’s what you need to know to get up to speed.

As a quick reminder, what is Bitcoin Cash again?

Bosch Boosts IOTA With New Device Connectivity For IoT Data Collection

Posted by in categories: bitcoin, cryptocurrencies, engineering, internet

Multinational engineering and electronics giant Bosch recently highlighted a new device connectivity method which will work with the Iota marketplace, among other things, for real-time IoT (Internet of Things) data collection and sales.

Data Collection for the IOTA Marketplace

In a recent blog post the firm opened with a quote from 1999 from Nobel Prize winner Milton Friedman extolling the virtues of anonymously transferring funds on the internet, way before cryptocurrencies were even conceived. It continued to elaborate on the Iota ecosystem, its advantages over Bitcoin, and why it has been chosen as a partner.

Blockchain millionaire plans smart city in Nevada desert

Posted by in categories: bitcoin, business, cryptocurrencies

Cryptocurrency millionaire Jeffrey Berns has revealed plans to develop a large parcel of Nevada’s desert into a smart city powered by blockchain technology.

Berns, who made a fortune selling cryptocurrency last year, plans to transform the 67,000-acre (27,113-hectare) plot in the north of the US state after paying reportedly paying $170 million (£130 million) for the land.

The site known as Innovation Park, which neighbours hubs of major tech giants including Google, Apple, Switch and Tesla, is already home to the headquarters of his company Blockchains – an incubator that supports ventures and businesses using blockchain technology.

Will we all be using a blockchain currency some day?

Posted by in categories: bitcoin, cryptocurrencies, economics, government

At Quora.com, I respond to quetions on Bitcoin and Cryptocurrency. Today, a reader asked “Will we all be using a blockchain-based currency some day?”.

This is an easy question to answer, but not for usual Geeky reasons: A capped supply, redundant bookkeeping, privacy & liberty or blind passion. No, these are all tangential reasons. But first, let’s be clear about the answer:

Yes, Virginia. We are all destined to move,
eventually, to a blockchain based currency.

I am confident of this because of one enormous benefit that trumps all other considerations. Also, because of flawed arguments behind perceived negatives.
