3  Bitcoin / Bitcoin Discussion / Roadblocks to a Decentralized Internet on: May 07, 2018, 08:23:58 PM
https://medium.com/@danielroseman/roadblocks-to-a-decentralized-internet-84e47c1bcb15

---START ARTICLE---

One of the great promises of blockchain technology (specifically, Turing complete blockchains such as Ethereum) is the concept of a Decentralized Application (AKA “ĐApp”) — an Internet service completely owned and operated by computer code with no human owners/operators. The idea of a Decentralized Internet has achieved some level of mainstream interest in the sense that is a central theme of the popular HBO series, Silicon Valley.

This article discusses a few popular critiques of today’s Centralized Applications (which I’ll call “CApps”), how ĐApps propose to remedy the shortcomings of CApps, and highlight several significant roadblocks which threaten the viability of a mainstream ĐApp ecosystem.

Today’s CApps are primarily criticized on three solid grounds. First is the fact that CApps have consolidated into Internet behemoths such as Google, Facebook, Twitter, etc.; these centralized capitalist ventures rely on humans (and their biases) to control the content on its platform, with little to no regulatory oversight.
This enables (in fact, requires) Facebook to apply subjective standards to regulate the content on its platform. For example, Facebook does not allow certain content considered “Cruel and Insensitive” or “False News” and cannot (by law) allow certain content, such as that deemed to be related to “Dangerous Individuals and Organizations.” This is flirting with the idea that “free speech gives us the right to offend,” but that’s a separate topic.

It also enables Google to provide personalized search results based on a plethora of data associated with your Google account and CApp browsing history. This means that Google search results are no longer the same for everyone, and is especially true if you are logged into your Google account while browsing.
The second critique of CApps is that these Internet conglomerates extract and sell personal identifying information to third parties without the full knowledge and consent of its users. This is the idea that “You’re the Product, Not the Consumer.”

Facebook, Twitter, Instagram, and even “sharing economy” services such as AirBnB and Uber all rely on its users to produce content for their respective platforms. The value these social media platforms offer their users comes from content produced by other users, not by the host platform. As TechCrunch contributor Tom Goodwin observed, “Uber, the world’s largest taxi company, owns no vehicles. Facebook, the world’s most popular media owner, creates no content. Alibaba, the most valuable retailer, has no inventory. And Airbnb, the world’s largest accommodation provider, owns no real estate. Something interesting is happening.”

Truth be told, the real, underlying consumers of social media platforms are advertisers and data miners — not end-users. Users get free access to these platforms, but only in exchange for producing both content and advertising opportunities. This arrangement enables abuses like Cambridge Analytica.
The third critique of CApps is that they rely on a centralized Internet infrastructure (ISPs) which are vulnerable to the whims of politics and special interests. This results in harmful regulatory actions such as the FCC’s recent decision to repeal Net Neutrality.

Blockchains are effective tools for censorship resistance. With ĐApps, “code is law” (as was the tagline of the defunct TheDAO project). The idea is that smart contracts are controlled by math, and we can trust the laws of math more than the judgement of humans. Thus, a Decentralized Facebook would not need a 10,000 person “content review team.” to determine which content is appropriate for its platform; it would publish all posts from all users with no filter.
ĐApps require users to completely own and control their own data. This has mixed implications, which I address later. However, Governments are starting to catch up with consumer’s privacy demands and are beginning to enforce consumer data controls with regulations such as GDPR.
Lastly, whether or not Ethereum ĐApps would be affected by Net Neutrality is still very much up for debate. Time will tell.

Despite the hype, there are serious roadblocks which threaten the viability of a healthy, mainstream Decentralized Internet.
One of the biggest issues is fairness. There already is an elite class of technocrats; current blockchain participants (digital asset holders) own 100% of the economic and utility token supply and will therefore have the most control and influence over the design and governance of a Decentralized Internet and the ĐApps built on it. This is especially true if the new decentralized Google/Facebook/Twitter/etc. adopt Proof of Stake as its consensus mechanism.
Then there is the governance issue. Governance requires humans; designing, building, and maintaining ĐApps will require at least some human input, which creates a risk of centralization.

Related to this is the difficulty in achieving near-perfect consensus for all ĐApp upgrades. A Decentralized Internet requires a near-perfect majority consensus on decisions affecting ĐApp development and maintenance. In order for a decentralized Facebook to stand a chance against its centralized counterpart, there can never be a chain split. Getting users to agree on the design and function of an app is extremely difficult, as Snapchat recently realized.
Identity and reputation are incredibly difficult challenges for ĐApps. A Decentralized Internet requires “tokenized identity” — the ability to encode/associate your online and/or real-world identity with a hash output on a Blockchain. The problem is that identity and reputation are by their nature very mutable — people change addresses, names, careers, marital statuses, die, etc. Thus, maintaining a blockchain record which is truly reflective of your online/real-world identity status requires a centralized data oracle, which again creates a risk of centralization.

There are pragmatic problems with how ĐApps actually work. Every state change in a ĐApp is an on-chain transaction which costs time and money. For example, users of centralized exchanges are able to create, modify, and delete market orders instantly and freely, thanks to centralized databases. The same is not true for decentralized exchanges, where each order creation, modification and deletion requires the user to send a transaction to the blockchain in order to update the state of the ledger and execute the command. An interesting side effect of this technical inefficiency is that it renders high-frequency trading cost-prohibitive on decentralized exchanges.

Lastly, ĐApps require users to create, own, and manage their own private keys. Unfortunately, this requirement would exclude a significant population of today’s Internet users (nontechnical, young, elderly, disabled) who may be unable to effectively control this vital piece of data.

I do not intend to suggest that blockchain development is not a worthwhile pursuit; it is, and scaling solutions as well as other important innovations will likely emerge in the process. When the dust settles, it is unlikely that we will see Google, Facebook, Twitter, etc. dissolve their corporate entities and surrender to the New Decentralized Overlords. Instead, they will likely integrate elements of their applications on the blockchain where it makes the most economic sense to do so.

That would be a boring outcome and I’d love to be proven wrong.

It's sad that Coinality is now for sale. To be honest with you, I actually used your service when I was looking for an assistant, specifically someone who could do my paperwork, and I saw that person in your resume section who could do it for me. So I am thankful.

But as the saying goes, “When one door closes, another opens.” I hope you guys behind Coinality find a new path that you can venture and make it grow better than what you achieved in Coinality.


Thanks for the story and the well wishes. It is with mixed feelings that we move on, but we will do everything we can to make sure Coinality ends up in good hands.

Coinality post: https://coinality.com/jobs/coinality-for-sale/

When I launched Coinality.com in September 2013, my goal was simply to connect with blockchain developers to discuss some apps that I wanted to develop. Back then, the ideas were simple - a wallet with a decent UI that could handle multiple cryptocurrencies.

However, it quickly became apparent that Coinality was filling a need in the community, as registered members and job/resume posts soared in the first month. I even got a 2.5 minute feature on Bloomberg's "Street Smart" TV show three months after launching!

So I stuck with it and decided to further develop Coinality using developer talent sourced exclusively via Coinality. I posted a job on Coinality.com to develop native iOS and Android apps - both projects came to fruition (at a great rate paid in BTC) and the developers were fantastic.

We partnered with the Plug And Play Tech Center to produce the World's First Bitcoin Job Fair in May 2014. Over 30 startups participated with over 400 people in attendance. Many success stories came out of the event, including a former Visa executive joining BitPay as Chief Compliance Officer. We subsequently held three other Bitcoin Job Fairs in NYC, Los Angeles, and Sunnyvale. The events were all successful, proving that Coinality was well-positioned in a growing industry.

We found Bitsapphire on Coinality and hired them to design and develop Coinality.io from scratch. A year and a half later we had a working prototype and over 200 pre-screened freelance blockchain developers ready to get to work. Unfortunately, we ran out of funds to support and maintain Coinality.io, and the platform is currently collecting dust in our Github repo. I learned some expensive but valuable lessons with Coinality.io.

I realized some time ago that I have done everything that I possibly can for Coinality. Time has come to move on.

Coinality.com currently enjoys an average of 250-300 unique visits per day, with visitors spending an average of 3 minutes onsite. The site has a 4.34% bounce rate, despite some much-needed optimizations. Coinality requires resources which I am no longer able to provide.

Accordingly, Coinality is for sale! Included in the sale are all assets and data related to:
  • Coinality.com (includes: website, iOS app, and Android app)
  • Coinality.io (includes full source code)
  • Bitcoinjobfair.com (including Bitcoinjobsfair.com)
  • Social media profiles (includes: Twitter, Facebook, LinkedIn group)

We are seeking acquirers that are interested in either further developing Coinality or integrating/absorbing Coinality into an existing related product or service. Cryptocurrency transaction preferred, but we are open to traditional payment methods. Additional data available upon request.

Ah yes, I can see how that might cause some confusion. No, Elance & oDesk don't actually post on Coinality; these jobs are sourced from Elance & oDesk and reviewed to ensure that they meet the criteria for Coinality - namely, that bitcoin be an option for compensation. We also source listings from Indeed, SimplyHired, and Craigslist.
