Diminishing Bitcoin Mining Rewards

Posted by in categories: bitcoin, cryptocurrencies, economics, internet, privacy

By now, most Bitcoin and Blockchain enthusiasts are aware of four looming issues that threaten the conversion of Bitcoin from an instrument of academics, criminal activity, and closed circle communities into a broader instrument that is fungible, private, stable, ubiquitous and recognized as a currency—and not just an investment unit or a transaction instrument.

These are the elephants in the room:

  • Unleashing high-volume and speedy transactions
  • Governance and the concentration of mining influence among pools, geography or special interests
  • Privacy & Anonymity
  • Dwindling mining incentives (and the eventual end of mining). Bitcoin’s design eventually drops financial incentives for transaction validation. What then?

As an Op-Ed pundit, I value original content. But the article, below, on Bitcoin fungibility, and this one on the post-incentive era, are a well-deserved nod to inspired thinking by other writers on issues that loom over the cryptocurrency community.

This article at Coinidol comes from an unlikely source: Jacob Okonya is a graduate student in Uganda. He is highly articulate, has a keen sense of market economics and the evolution of technology adoption. He is also a quick study and a budding columnist.

Bitcoin Fungibility: A Benefit of privacy & anonymity

Posted by in categories: bitcoin, cryptocurrencies, economics, internet, privacy

I was pointed to this article by Jon Matonis, Founding Director, Bitcoin Foundation. I was sufficiently moved to highlight it here at Lifeboat Foundation, where I am a contributing writer.

On Fungibility, Bitcoin, Monero and ZCash … [backup]

This is among the best general introductions I have come across on traceability and the false illusion of privacy. The explanation of coin mixing provides and coin_mixing-03excellent, quick & brief overview.

Regarding transaction privacy, a few alt-coins provide enhanced immunity or deniability from forensic analysis. But if your bet is on Bitcoin (as it must be), the future is headed toward super-mixing and wallet trading by desgin and by default. Just as the big email providers haved added secure transit,
Bitcoin will eventually be fully randomized and anonymized per trade and even when assets are idle. It’s not about criminals; it’s about protecting business, government and individuals. It’s about liberty and our freedoms. [Continue below image]

California Space Center announces blockchain system for space economy

California Space Center (CSC) founder Eva Blaisdell announced in a press release sent to CoinReport the launch of “Copernic,” a blockchain-based, finance-focused rights management system developed for the space industry.

Named after legendary Polish astronomer Copernicus, Copernic will provide the infrastructure for the future space economy and ecosystem to be built upon, said CSC.

DARPA investigating blockchain for nuclear weapons, satellite security

Posted by in categories: bitcoin, cybercrime/malcode, military

If the Defense Department is looking to implement blockchain, other organizations may quickly follow suit. Blockchain technology helps guarantee that information has a timestamp and recorded whenever any change happens, ensuring data can be trusted in real time. In DARPA’s case, blockchain technology could help track attempted data breaches.

“Whenever weapons are employed … it tends to be a place where data integrity in general is incredibly important,” Booher said. “So nuclear command and control, satellite command and control, command and control in general, [information integrity] is very important.”

In September, DARPA awarded a $1.8 million contract to computer security firm Galois, asking it to verify a specific type of blockchain technology from a company called Guardtime. If the verification goes well, the military could become one of a growing number of industries and institutions using blockchain to help ensure the security of their operations.

Will Quantum Computers Kill Bitcoin?

Posted by in categories: bitcoin, cybercrime/malcode, encryption, quantum physics

Since they were first theorized by the physicist Richard Feynman in 1982, quantum computers have promised to bring about a new era of computing. It is only relatively recently that theory has translated into significant real-world advances, with the likes of Google, NASA and the CIA working towards building a quantum computer. Computer scientists are now warning that the arrival of the ultra-powerful machines will cripple current encryption methods and as a result bring a close to the great bitcoin experiment—collapsing the technological foundations that bitcoin is built upon.

“Bitcoin is definitely not quantum computer proof,” Andersen Cheng, co-founder of U.K. cybersecurity firm Post Quantum, tells Newsweek. “Bitcoin will expire the very day the first quantum computer appears.”

The danger quantum computers pose to bitcoin, Cheng explains, is in the cryptography surrounding what is known as the public and private keys—a set of numbers used to facilitate transactions. Users of bitcoin have a public key and a private key. In order to receive bitcoin, the recipient shares the public key with the sender, but in order to spend it they need their private key, which only they know. If somebody else is able to learn the private key, they can spend all the bitcoin.

Quantum Computing Could Cripple Encryption; Bitcoin’s Role

Posted by in categories: bitcoin, business, cybercrime/malcode, encryption, government, quantum physics

Earlier this week, Canada’s electronic spy agency the Communications Security Establishment warned government agencies and businesses against quantum mechanics, which could cripple the majority of encryption methods implemented by leading corporations and agencies globally.

Governments and private companies employ a variety of cryptographic security systems and protocols to protect and store important data. Amongst these encryption methods, the most popular system is public key cryptography (PKC), which can be integrated onto a wide range of software, platforms, and applications to encrypt data.

The Communications Security Establishment and its chief Greta Bossenmaier believes that quantum computing is technically capable of targeting PKC-based encryption methods, making data vulnerable to security breaches and hacking attempts from foreign state spies and anonymous hacking groups.
