Ethereum clients that still haven’t patched known vulnerabilities pose a security risk to the entire network, according to new research.
A report from Security Research Labs that used ethernodes.org data, indicates that a large number of nodes using the most popular clients Parity and Geth have been left exposed for “extended periods of time” after patches for security flaws have been released.
A third of all ether, ethereum’s native cryptocurrency, is owned by just 376 whales as of May 1, new research indicates.
Blockchain analysis startup Chainalysis published a study on Wednesday, indicating that, while these 376 individuals control 33 percent of the circulating supply in 2019, that number is actually down from levels seen in 2016 and 2017.
In the technology industry, there are always some developments which might not entirely seem possible at first. A great example comes in the form of recent achievement by Michigan State University researchers. Their plan is to create transparent solar panels which can be placed over a window to harvest solar energy.
Windows Turn Into Solar Panels, of Sorts
As the need for renewable energy sources increases on a global scale, new solutions need to be created to allow for such growth.
The U.S. Department of Energy is exploring blockchain technology as a line of defense against cyberattacks on power plants.
The department’s National Energy Technology Laboratory (NETL) unit announced Wednesday that phase two of an electric grid security project has been launched in partnership with decentralized cybersecurity startup Taekion, formerly Grid7.
The laboratory provided a grant of $1 million to Taekion last year, and now as part of the second phase of the project, the startup will research on how blockchain technology can be used to secure a power plant, by keeping all sensor, actuator and device transactions on a distributed ledger.
A new report by the software firm DataLight predicted that Bitcoin could become the world’s top payment system within the next decade if it maintains its current growth rate.
“In just 10 years, Bitcoin has managed to compete with the leaders of the payment system industry,” the report found. “Bitcoin’s development is occurring exponentially.
A newly established blockchain industrial park in the Chinese city of Hangzhou is hoping to attract talented individuals and startups by offering millions of dollars-worth of subsidies.
A policy guide announcing the incentives was published on Thursday via the official WeChat account of the Xiong’An Fund (which translates as “Grand Shores Fund”) – the primary operator of the blockchain complex, both of which were launched in April.
Japanese consumers filed over three times the number of enquiries about cryptocurrency trading and initial coin offerings in 2017 as compared to the previous year, according to data released by Japan’s Consumer Affairs Agency (CAA).
The numbers were disclosed at the second cryptocurrency exchange study group meeting hosted by Japan’s Financial Services Agency (FSA) on April 27, providing a glimpse into the country’s spiking interest in, and also concerns about, the cryptocurrency space.
In a demonstration titled “Wallet.fail,” a team of security researchers hacked into the Trezor One, Ledger Blue and Ledger Nano S. Unfortunately, it appears as if their findings were first put on display at the 35th Chaos Communication Congress (35C3) in Leipzig, Germany, rather than through accepted Responsible Disclosure practices, which would have allowed the manufacturers to patch the vulnerabilities and protect their customers from any potential attack.
Selfish mining is an attack on the Bitcoin network that has been known to be possible for several years. By propagating new blocks slowly (on purpose or by accident), a loophole is opened for miners to unfairly increase their profits in relation to other miners.
However, researchers Cyril Grunspan and Ricardo Pérez-Marco claim that by broadcasting the presence of orphan blocks, selfish mining can become a thing of the past.
Grunspan, a professor at Paris’ ESILV graduate school of engineering, and Pérez-Marco, the director of research at the National Center for Scientific Research (CNRS) in Paris, have authored a report on the costs of selfish mining and its profitability, which they believe have been largely ignored by the Bitcoin community.
Popular cryptocurrency exchange Binance announced today that it has launched a new division dedicated specifically to industry analysis.
In a November 8, 2018, announcement, Binance described some of the responsibilities of this new division, which has been dubbed Binance Research.
In a newly published paper on the use of bitcoin for illegal activity, researchers from the University of Sydney, the University of Technology Sydney and the Stockholm School of Economics in Riga indicate that a quarter of all bitcoin users are associated with illegal activity.
Owning cryptocurrency comes with its own set of challenges. One of the biggest of those challenges is managing the private keys that enable you to spend funds. Lose your private keys, and your money is gone.
In a business environment, a common way to manage funds owned by multiple people is via what’s called a multisignature (multisig) address, a type of smart contract requiring two or more parties to sign off on a transaction to move the funds.
As a way to eliminate bugs in high-risk code, a style of software programming known as formal verification is making its way into the blockchain world.
Put simply, formal verification uses math to specify and analyze a program for errors in logic.
Researchers from several European universities have joined the Initiative for Cryptocurrencies and Contracts (IC3), a research effort set up to develop new cryptocurrency systems.
Faculty members at ETH Zurich, Swiss Federal Institute of Technology in Lausanne (EPFL), and University College London (UCL) have become the latest to the join the initiative, which launched in 2015 with financial backing from the U.
The European wing of the RAND Corporation, a US think tank, has argued for a slow-and-steady process for developing possible standards around blockchain.
In a new report published on October 18 and prepared for the British Standards Institution (BSI) – the world’s first group of its kind and the official standards body for the United Kingdom – the think tank identified several areas that could be the target for standards developers.
The bitcoin price took a dive on Friday, initiating speculation that the market’s post-China hangover is not going away anytime soon.
Bitcoin entered the week on an incline, quickly recovering from its September 15 flash crash below $3,000. Within two days of that low-point, the bitcoin price had stabilized above $3,500. By September 18, bitcoin had cracked the $4,000 barrier for the first time since the downturn. However, bitcoin found itself unable to advance past that mark, and on September 21 it began to lose its footing.
Germany's central bank has published a new research paper centered on distributed ledger tech (DLT), exploring its use for payments, securities settlement and more.
Researchers from the Deutsche Bundesbank wrote in the paper that the tech "offers a number of benefits on account of the distributed storage of data" – highlighting both the potential opportunities as well as some of the practical challenges any application might create.
In an English-language explainer published alongside the paper (the original version is in German only), the German central bank noted that it doesn't see much of a role for the tech in consumer payments, arguing:
"The Bundesbank’s experts see little prospect of DLT being put to widespread use in the field of individual and retail payments given the current state of the art.
Regardless of its recent crackdown on bitcoin exchanges and initial coin offerings (ICOs), China's government still appears committed to the potential of blockchain in other areas.
According to a report by Caixin, the China Academy of Information and Communications Technology (CAICT) – a research institution under the Ministry of Industry and Information Technology – has launched a research facility called the Trusted Blockchain Open Lab in order to support the ongoing development of the technology in China.
