The decentralized web will be as big a game changer as the internet was in the '90s

Cryptocurrencies have had their time in the spotlight. Now it's time to focus on solving bigger problems.

The decentralized web will be as big a game changer as the internet was in the '90s
  • The internet has witnessed many big developments since it was created. The next big one will be decentralization.
  • Right now, the internet is centralized, which cause many issues, not the least of which is big companies having power over vast amounts of data.
  • Over the past few years there has been a major increase in the number of decentralized projects working on making the decentralized web a reality in the near future.

We've come a long way since Tim Berners-Lee created the internet back in 1990.

What was once nothing more than a mere twinkle in his eye has become the center-point of the lives of millions of people all around the world.

From giving us instant access to information and helping us stay in touch with our friends and family members who live on the other side of the globe to helping us to do our weekly shopping without having to get out of bed and enabling us to collect and breed digital cats, the internet has enabled many changes — for better and for worse.

However, now that we seem to have understood more or less how and when to use the web, communication is about to change all over again.

‘Decentralization’ is the new big buzzword

We've made some rapid developments in technology over the past few years.

Artificial intelligence, virtual reality, and of course, cryptocurrencies, have been all over the headlines and have attracted a huge amount of attention as a result.

Now, the next step for the web is decentralization — and it's kind of a big deal.

Why do we need a decentralized web?

With all our data in the hands of a small number of huge centralized corporations, we are at the mercy of hackers, increased surveillance, and increased censorship.

Since the recent reports of Google — a company that has always prided itself on bringing the fairest, most accurate search results in the world to its users — working on a censored search engine for China, there have been mounting concerns by human rights groups about the future of the web.

In an interview, Patrick Poon, a China researcher for Amnesty International, stated, "In putting profits before human rights, Google would be setting a chilling precedent and handing the Chinese government a victory."

Considering how much of a monopoly Google currently has on the web (think YouTube, Google News, Google Maps, Google Drive and Google AdWords), such news is quite startling — and a little scary.

The big question many people are finding themselves asking is: What's the alternative?

It turns out, an encrypted, blockchain-operated decentralized web could be the answer.

Who are the major companies involved?

Over the past couple of years, there has been a significant rise in the number of companies dedicating their time, money, and resources to creating decentralized alternatives for some of the most popular centralized products.

TRON is one of the projects dedicated to establishing a decentralized web.

As one of the largest blockchain-based operating systems in the world, it has high throughput and can currently support approximately 2,000 transactions per second, drastically surpassing the likes of Bitcoin and Ethereum, which can support only 3-6 transactions and 25 transactions per second respectively.

It also has high scalability and availability options which can support a huge number of users. The team's overall long-term goal is to make decentralized software more versatile in order to, ultimately, expand the industry.

The TRON team is made up of over 100 experienced international blockchain enthusiasts, who have a significant amount of experience and have been employed by internet giants such as Alibaba, Tencent, and Baidu.

Earlier this year, TRON announced Project Atlas, in which they acquired file-sharing giant BitTorrent. The move marks the first major crossover between file sharing and decentralized technology, and has helped increase TRON's profile.

Meanwhile, companies like Graphite Docs have made a decentralized alternative to Google Docs that encrypts all your work, files, and messages, while still making them shareable.

Unlike a centralized service where your private information is at the hands of the provider, the files stored on Graphite Docs are completely owned by the user.

Similarly, projects like Skycoin are developing the backbone of a new decentralized internet, with a mesh network that pays users for supporting it. The Skycoin project and specifically its leading product Skywire has over 9,500 nodes online. One of the project's community members even built a dedicated page with a regularly updated map of all active nodes around the world.

Skywire's current testnet has functions similar to TOR but is actually much faster. Community members can build and operate their own simple DIY nodes called 'Skyminers' to access and expand the mesh network. Soon, they will also be able to purchase officially sanctioned Skyminers from Skycoin's website. During the testnet phase, running an approved Skyminer on the network earns Skycoin currency on a monthly basis. When mainnet launches these Skyminers will earn currency based on how much bandwidth they forward and process. This project, like many others with net-neutrality values at their core, is aiming to bring freedom and power back to the users and away from centralized, controlling ISPs and governments.

The future of the internet

We're still a long way off complete decentralization, but the popularity of the concept is becoming increasingly apparent.

As the problems of centralization become more obvious, it's likely that we'll continue to see a huge push towards a decentralized future as we move further into 2019.

A landslide is imminent and so is its tsunami

An open letter predicts that a massive wall of rock is about to plunge into Barry Arm Fjord in Alaska.

  • A remote area visited by tourists and cruises, and home to fishing villages, is about to be visited by a devastating tsunami.
  • A wall of rock exposed by a receding glacier is about crash into the waters below.
  • Glaciers hold such areas together — and when they're gone, bad stuff can be left behind.

The Barry Glacier gives its name to Alaska's Barry Arm Fjord, and a new open letter forecasts trouble ahead.

Thanks to global warming, the glacier has been retreating, so far removing two-thirds of its support for a steep mile-long slope, or scarp, containing perhaps 500 million cubic meters of material. (Think the Hoover Dam times several hundred.) The slope has been moving slowly since 1957, but scientists say it's become an avalanche waiting to happen, maybe within the next year, and likely within 20. When it does come crashing down into the fjord, it could set in motion a frightening tsunami overwhelming the fjord's normally peaceful waters .

"It could happen anytime, but the risk just goes way up as this glacier recedes," says hydrologist Anna Liljedahl of Woods Hole, one of the signatories to the letter.

The Barry Arm Fjord is a stretch of water between the Harriman Fjord and the Port Wills Fjord, located at the northwest corner of the well-known Prince William Sound. It's a beautiful area, home to a few hundred people supporting the local fishing industry, and it's also a popular destination for tourists — its Black Sand Beach is one of Alaska's most scenic — and cruise ships.

There have been at least two similar events in the state's recent history, though not on such a massive scale. On July 9, 1958, an earthquake nearby caused 40 million cubic yards of rock to suddenly slide 2,000 feet down into Lituya Bay, producing a tsunami whose peak waves reportedly reached 1,720 feet in height. By the time the wall of water reached the mouth of the bay, it was still 75 feet high. At Taan Fjord in 2015, a landslide caused a tsunami that crested at 600 feet. Both of these events thankfully occurred in sparsely populated areas, so few fatalities occurred.

The Barry Arm event will be larger than either of these by far.

"This is an enormous slope — the mass that could fail weighs over a billion tonnes," said geologist Dave Petley, speaking to Earther. "The internal structure of that rock mass, which will determine whether it collapses, is very complex. At the moment we don't know enough about it to be able to forecast its future behavior."

Outside of Alaska, on the west coast of Greenland, a landslide-produced tsunami towered 300 feet high, obliterating a fishing village in its path.

What the letter predicts for Barry Arm Fjord

"The effects would be especially severe near where the landslide enters the water at the head of Barry Arm. Additionally, areas of shallow water, or low-lying land near the shore, would be in danger even further from the source. A minor failure may not produce significant impacts beyond the inner parts of the fiord, while a complete failure could be destructive throughout Barry Arm, Harriman Fiord, and parts of Port Wells. Our initial results show complex impacts further from the landslide than Barry Arm, with over 30 foot waves in some distant bays, including Whittier."

The discovery of the impeding landslide began with an observation by the sister of geologist Hig Higman of Ground Truth, an organization in Seldovia, Alaska. Artist Valisa Higman was vacationing in the area and sent her brother some photos of worrying fractures she noticed in the slope, taken while she was on a boat cruising the fjord.

Higman confirmed his sister's hunch via available satellite imagery and, digging deeper, found that between 2009 and 2015 the slope had moved 600 feet downhill, leaving a prominent scar.

Ohio State's Chunli Dai unearthed a connection between the movement and the receding of the Barry Glacier. Comparison of the Barry Arm slope with other similar areas, combined with computer modeling of the possible resulting tsunamis, led to the publication of the group's letter.

While the full group of signatories from 14 organizations and institutions has only been working on the situation for a month, the implications were immediately clear. The signers include experts from Ohio State University, the University of Southern California, and the Anchorage and Fairbanks campuses of the University of Alaska.

Once informed of the open letter's contents, the Alaska's Department of Natural Resources immediately released a warning that "an increasingly likely landslide could generate a wave with devastating effects on fishermen and recreationalists."

How do you prepare for something like this?

The obvious question is what can be done to prepare for the landslide and tsunami? For one thing, there's more to understand about the upcoming event, and the researchers lay out their plan in the letter:

"To inform and refine hazard mitigation efforts, we would like to pursue several lines of investigation: Detect changes in the slope that might forewarn of a landslide, better understand what could trigger a landslide, and refine tsunami model projections. By mapping the landslide and nearby terrain, both above and below sea level, we can more accurately determine the basic physical dimensions of the landslide. This can be paired with GPS and seismic measurements made over time to see how the slope responds to changes in the glacier and to events like rainstorms and earthquakes. Field and satellite data can support near-real time hazard monitoring, while computer models of landslide and tsunami scenarios can help identify specific places that are most at risk."

In the letter, the authors reached out to those living in and visiting the area, asking, "What specific questions are most important to you?" and "What could be done to reduce the danger to people who want to visit or work in Barry Arm?" They also invited locals to let them know about any changes, including even small rock-falls and landslides.
