Say “Goodbye” to Expensive Roaming Costs and “Hello” to Cheaper Smart Contracts as Top Experts Join the Bubbletone Team
Say “Goodbye” to Expensive Roaming Costs and “Hello” to Cheaper Smart Contracts as Top Experts Join the Bubbletone Team

If Bubbletone’s founder and CEO, Yuri Morozov, has anything to say about it, the world of roaming mobile telecommunications is about to crumble. And Morozov definitely has a lot to say. But he’s not alone. He’s assembled a team of top-notch advisors with deep credentials in the telecom and crypto spheres to aid him in his quest to revolutionize mobile roaming as we know it. Late in January the company welcomed internationally renowned crypto guru and TechCrunch co-founder, Keith Teare to their advisory board. “I have made it my life’s work to seek out and support ambitious new projects, and I have always focused on the point at which change is happening,” says Teare. “It’s my opinion that the massive global roaming market is ripe for major reforms, and Bubbletone’s blockchain platform will bring the much-needed change into telecom technology.”

Also joining the Bubbletone advisory team are top-five world blockchain advisor, Anders Larsson, along with telecom expert Joakim Holmer and Dr. Norman Lewis, a prominent future trends and user innovation expert. The new advisors join the company with an impressive array of expertise and experience in the telecom and blockchain worlds. Joakim Holmer is a co-founder of AllcoinWiki, “the true source of crypto” and worked for the Ericsson Group for over 15 years. He has built digital mobile networks all over the world. “Roaming fees have always been and still are destructive for the whole industry,” he argues. “Finally a great project like Bubbletone takes on the task to disrupt the industry. We are strong supported and honored to be hired as Trusted Advisors to the great project.”

Holmer is joined by his AllcoinWiki co-founder Anders Larsson, who also worked with Ericsson Group and has over 20 years’ experience developing the emerging technologies of 2G, 3G, 4G, 5G, and IoT in ten different countries. For Larsson, joining the team was personal. “Seeing that blockchain can fix roaming was enough to decide that I want to help Bubbletone with advice, wherever I can. I feel it is important for the competitiveness of the entire telecom industry, or my home industry that I love will end up losing market share to Wi-Fi,” he says. “In short, this is something I look forward to using myself. That yardstick has served me well all my life.”

Dr. Norman Lewis has been a long-time critic of traditional telecommunications and is a natural ally to Morozov’s way of thinking. The telecom expert has been Director of Technology Research at Orange UK and was an executive board member of MIT’s Communications Futures Program. Lewis has expressed frustration in the past about telcos’ lack of modernization, going so far as to charge the industry itself with stifling innovation Dr. Lewis believes any pressure to change in the past has come from the advances in internet telephony. That’s why he is jumping on board with Bubbletone, because he believes that blockchain technology will usher in the next telecom revolution.

With 20 years of experience in the telecom industry, Morozov has recognized for some time that traditional mobile roaming service around the world is inefficient, overpriced, and effectively operates as a monopoly that keeps small- and medium-sized service providers out of the market. So Morozov and his development team, who can already claim success in the industry with their popular mobile app that allows customers to access local plans during travel with no roaming fees, set about to change the global telecom world using blockchain technology. The Bubbletone platform aims to circumvent these types of exclusionary hurdles by allowing operators to offer local service at competitive prices, all enabled by smart-contracts through blockchain technology.

According to Morozov, the roaming business today is like a private club; to gain access you have to pay some serious dues, in the tens of millions of dollars. Then without fail you will be asked how many clients you bring to the roaming market. “After all, if you are not a monopoly player in your own territory, then you can hardly guarantee a large volume of tourists to operators in other countries,” he points out. For Morozov, his team of advisors are crucial for ensuring that this outdated system is finally overturned. “Keith, Joakim, Anders and Norman all bring many years of research and experience in both telecom and blockchain innovation. They will hold our feet to the fire to ensure that we are creating the best product that will truly change the global telecom landscape, and because they come from various backgrounds, they will help us structure our product so that it truly meets the needs of our potential users worldwide,” says Morozov.

BMW Looks to the Blockchain to Prove Ethical Sourcing of Cobalt

Just about two-thirds of the world’s supply of cobalt originate from the Democratic Republic of Congo wherein about one-fifth of this cobalt supply come from what are known as “artisanal mines,” or in other words unregulated mining operations. Within these mines, it is not uncommon to find children who have been forced to forgo education, play and other important aspects of childhood to toil within these unregulated “artisanal” cobalt mines. However, with the use of the blockchain, some companies are looking to put a stop to this.

Cobalt is one of the most expensive materials when it comes to creating powerful and long-lasting batteries such as that used in electric automobiles. Since cobalt can end up coming from such sources as these mines, it puts companies in a strange position that, until now, there was no efficient way to ensure ethical sourcing for these types of minerals, a company just had to rely on the word of their supplier.

Circulor is a UK startup looking to put an end to this, and as a larger goal to lower the costs of creating electric vehicles. They plan to map out the already known clean sources of cobalt, such as that coming from Canada, the U.S. and certain well-regulated operations from within Congo. By mapping out the main part of the journey for these sources with the efficiency of the blockchain it should reduce regulatory costs immensely, as the technology is a guaranteed reliable source once put into the ledger.

Companies that are not sourcing their cobalt ethically will not be on this map until proven otherwise, and any supplies who attempt to use tainted supplies of the metal will be found out immediately.

Once this mapping is done the economic feasibility of this project will be shown, one way or the other, and the next step would be to move it into the less regulated areas of the world in hopes to force companies away from child labor.

In an interview Circular CEO Douglas Johnson-Poensgen had this to say:

“We believe it makes economic sense to start with sources that aren’t a problem… Once the system is proven and operating at scale, one can tackle the harder use cases like artisanal mines.”

Though this is just the beginning of this project, the efficiency of the blockchain is quickly being seen around the world by companies in many different industries, its ability to transfer and store information outside of the hands of those that may wish to manipulate is highly invaluable for these humanitarian efforts.

Ensuring transparency in the supply chain of diamonds is another real-life use case of blockchain technology, as demonstrated by Everledger, which was higlighted by BTCManager in February 2017.

The Ethereum Killer Is Ethereum 2.0: Vitalik Buterin’s Roadmap

VitalikTalk.jpg

Speaking on November 25 at BeyondBlock Taipei 2017, Ethereum inventor and co-founder Vitalik Buterin outlined his vision for Ethereum 2.0. He described major changes in Ethereum’s architecture that are likely to be implemented over the next few years to improve Ethereum in terms of privacy, safety (consensus safety and smart contract safety) and, of course, scalability, which was the main focus of Buterin’s talk.

Buterin doesn’t seem worried about competitors. “The Ethereum killer is Ethereum, the Ethereum of China is Ethereum, the Ethereum of Taiwan is Ethereum… 2.0,” he said.

The fact that Ethereum is booming seems to confirm Buterin’s optimism. ETH’s price has been relentlessly climbing, recently reaching almost $500, and Ethereum is handling more transactions than all other major blockchains combined.

Decentralization, scalability and security are among the important properties that blockchain systems should have, but there are conflicts. Off-chain solutions are useful, but limited. According to Buterin, it’s very easy to have two of these properties but very hard to have all three. However, Ethereum’s ambitious goal should be that of achieving all three at the same time. “We want to scale to thousands of transactions per second, on chain, without any supernodes,” reads one of Buterin’s slides.

Sharding

Sharding — dividing a blockchain network into several smaller component networks (called shards) capable of processing transactions in parallel — is considered to be a promising way to achieve high throughputs comparable to the thousands of transactions per second of traditional payment networks such as Visa and MasterCard.

“You can think of [sharding] as, in a fairly simple version, creating a blockchain where you have, let’s say, a hundred different universes, and each of these universes is a different account space,” said Buterin. “So you can have an account in some universe or you can have a contract in some universe and you can send a transaction in some universe, and if you send a transaction in some universe it only affects stuff in some universe.

“But these kind of 100 universes are not just separate blockchains; they are systems that are also interconnected with each other,” continued Buterin. “Particularly, they share consensus. So in order to break even one of them, you have to break the whole thing.”

Buterin went on to describe relatively easy and more sophisticated ways to implement sharding in the Ethereum blockchain, outlining a sharding roadmap that foresees, at least initially, the creation of new “universes” that don’t impact the main chain while permitting iterative experimentation, such as introducing higher levels of scalability, starting with “quadratic scalability as nodes validate certain shards and act as light clients for other shards.”

Privacy

Buterin noted that zero-knowledge proof (zk-Snarks) privacy technology equivalent to Zcash has been implemented in the recent “Byzantium” Ethereum upgrade, offering application developers new ways to implement tighter privacy. These new privacy tools will permit showing transactions to specific parties while hiding them from public view. Buterin went as far as saying that the privacy problem is now three quarters of the way to being solved.

Proof of Work vs. Proof of Stake

A major upgrade to Ethereum will be the introduction of Proof of Stake (PoS) in Casper which, according to Buterin, might be ready by next summer. With the first release of Casper, Ethereum will transition from pure Proof of Work (PoW) to hybrid PoW/PoS. “In this scheme, all of the proof-of-work mechanics will continue to exist, but additional proof-of-stake mechanics will be added,” noted Buterin.

The main reason why PoS is seen as a necessary development is, of course, the need to reduce the energy requirements of PoW blockchains like the current versions of Ethereum and bitcoin. A recent report claims that bitcoin mining consumes as much power in a year as 159 countries, which is clearly far too much, and Buterin admitted that today’s Ethereum isn’t any better than bitcoin in that respect.

Smart Contract Security

Smart contracts implemented with Turing-complete programming languages are arguably the main innovation introduced by Ethereum. While smart contracts are finding countless applications and moving lots of money, the security and safety of Ethereum smart contracts have been questioned. Buterin confirmed that Ethereum will eventually introduce formal verification for smart contracts and that a new Python-like smart-contract programming language — dubbed “Viper” — is being implemented to enable the development of safer Ethereum applications.

While Buterin hasn’t said anything that he has not said in previous talks and papers, his BeyondBlock talk served as a useful confirmation and summary of the ambitious Ethereum development roadmap.

Besides Buterin’s talk, all the talks given at BeyondBlock Taipei 2017 are included in the full video recordings of the morning session and the afternoon session.
