Sharding: What it is and why many blockchain protocols rely on it

3 weeks 4 days ago

As blockchains are being rolled out in an increasing number of pilot programs for everything from cross-border financial transactions to supply chain management, one persistent issue remains: a lack of scalability.

As more computers join the peer-to-peer network, the efficiency of the whole system typically degrades.

[ Further reading: What is FinTech (and how has it evolved)? ]

Scalability has already been identified as an issue with cryptocurrencies such as bitcoin and Ethereum's Ether. If a distributed ledger is to achieve adoption by financial technology (FinTech) companies and compete with payment networks hundreds of times faster, it must find a way to boost scalability and throughput and address latency problems.

Start-up Devvio claims its blockchain can handle 8M transactions a second

1 month ago

A start-up firm claims its highly efficient distributed ledger protocol can address all the major problems facing blockchain networks, including being able to scale for global financial business by executing up to eight million transactions per second (TPS).

The new blockchain protocol, called Devv, was unveiled and demonstrated at CES in Las Vegas last week.

If the claims prove true, Devv would be able to compete with traditional financial networks in terms of scalability, be far less expensive to use and would address fraud, theft and privacy issues. Like many blockchain protocols, Devv is not just a peer-to-peer (P2P) database technology but also a digital currency or cryptocurrency called Devcash.

How to create and open compressed files on iPhone, iPad

1 month 1 week ago

Many enterprises rely on zip files to exchange data, particularly confidential data. And compression helps keep information safe, even against inquisitive ads trackers lurking inside “free” email or online storage services. How do you handle these things on iPad or iPhone?

How to handle zip files on iPhone

While it isn’t especially obvious, iOS provides some limited features that let you archive and decompress zip files. You can even create a nice little Shortcut to do this for you:

  • Open Shortcuts, Tap Create Shortcut.
  • In the search bar, type Extract Archive: That shortcut should appear in the list below; tap it to add it to your workflow.
  • Returning to the search bar, type Save File. When it appears, tap it to add it to the workflow you are building.
  • Tap the switch button at top right of the shortcut name.
  • In the next pane, you can name the shortcut and give it an icon. The most important change you should make is to enable Show in Share Sheet (flick to green).
  • You can create a second Shortcut to make archives. Just type Make Archive to find the relevant flow and then add Save File and Show in Share Sheet as decribed above. Remember to give it a name, such as Make Archive.
  • Shortcuts can work with multiple compression formats, including .tar, .zip and .iso.

Mingis on Tech: As blockchain hype cools, a 'trough of disillusionment' for 2019?

1 month 1 week ago

Ok, so maybe blockchain isn't ready yet to become the biggest new technology since the internet.

But the distributed ledger technology clearly made strides in 2018, when it was embraced by companies from Walmart to shipping bigwig Maersk to top tech venders like IBM, SAP, Oracle and Microsoft who see potential in blockchain-as-a-service. (Walmart's vice president in charge of food safety, Frank Yiannas, compared his embrace of blockchain to a "religious conversion.")

Details, details

1 month 1 week ago

It's a few years after Y2K when the IT security team at this university gets a rude awakening, reports a pilot fish in the know.

"They discovered that persons unknown had hacked into a university server," fish says. "It was being used to launch denial-of-service attacks against a victim somewhere outside the university."

The team's first job is finding the server -- which turns out to be in the alumni office -- and taking it offline.

Then they start digging into the security logs. That's when they find out that the attackers have been making use of the server for more than a year.

And once they start checking on the IP addresses of whoever it is that has accessed the server, they discover it's not just one or two hackers. It seems people from all over the world have been using this server to launch attacks.

Top 4 enterprise tech trends to watch in 2019

1 month 2 weeks ago

If 2018 was the year of the data breach, the thinking among IT pros is that this will be the year companies take concrete steps to prevent future breaches.

That was the sentiment among tech professionals who took part in a recent @IDGTechTalk Twitter chat about enterprise tech trends for 2019.

In fact, a recent @IDGTechTalk poll found privacy and security to be the top enterprise tech issue for 2019 (45 percent), followed by artificial intelligence (30 percent), cloud computing (16 percent), and blockchain (9 percent).

Apple wants to stop you from using dangerous USB-C devices

1 month 2 weeks ago

Apple wants to make it harder for its customers to use cheap USB-C cables — and it’s for your own good.

The risks of USB-C cables

Cables are complicated, and that’s why friends don’t let friends connect cut-price or otherwise unverified USB-C cables to their systems — and soon, you won’t be able to.

Apple has warned its users to avoid using low-quality equipment for years. It was only in 2016 that it was revealed that hundreds of chargers at that time sold on Amazon and advertised as being made by Apple were in fact dangerous fakes.

New year, same old users

1 month 2 weeks ago

IT support pilot fish takes a call to help a user change a password on a webpage form -- and it reminds fish of just how much help-desk techs love password resets.

"I spent 25 minutes talking to him," fish groans. "There were only two buttons to press, Submit and Reset.

"You’d think that after pressing Reset three times and having it erase the passwords he typed in, he would try Submit -- right?

"But no -- our customer tried a fourth and then a fifth time, until he got the idea to hit the other button.

"This person was by all accounts a functional, employed adult..."

If the CTO says it's OK, what could go wrong?

1 month 2 weeks ago

Medical rehab facility is facing a compliance deadline for HIPAA privacy regulations, and that could be a problem, says a cybersecurity pilot fish working there.

"The HIPAA regulations are strewn with potential issues," fish says. "When some aspect isn't followed and a patient's data privacy is compromised, the fines can be substantial."

And that's the headache fish faces because of his facility's use of Gmail. As the site's cybersecurity engineer, fish knows that ordinary Gmail isn't HIPAA compliant.

Fortunately, there's a fix -- one that involves additional paperwork and agreements, along with some added security verification. But that's still easier and less complex than moving everyone off Gmail.

Q&A: Experian exec says biometrics won’t save you from mobile hacks

1 month 3 weeks ago

If you think your new iPhone's Face ID facial recognition feature or your bank's fancy new fingerprint scanner will guarantee privacy and block hackers from accessing sensitive personal or financial data, think again.

In the coming year, cyberattacks will zero in on biometric hacking and expose vulnerabilities in touch ID sensors, facial recognition technology and passcodes, according to a new report from credit reporting agency Experian Plc. While biometric data is considered the most secure method of authentication, it can be stolen or altered, and sensors can be manipulated, spoofed or suffer deterioration with too much use.

Even so, as much as 63% of enterprises have implemented or plan to roll out  biometric authentication systems to augment or replace less-secure passwords, Experian said in its report. The push toward biometric systems dates back to the turn of the century in the financial services industry.
