Bitcoin Scaling:
Jeff Garzik AsicBoost Comments
Lead to Frustration

    

Bitcoin Core developer

Jeff Garzik has sparked contention with a post asking if further measures were needed to prevent covert AsicBoost. Addressing the work group (WG) on Github, Garzik put forward a selection of next steps aimed at “testing protocol/software changes that ban/disable/render ineffective this hardware optimization.” However, fellow contributor Greg Maxwell responded accusing Garzik of attempting to allow AsicBoost to, in fact, continue under his “modified version” of Segregated Witness with a hard fork.

Maxwell wrote:

“So to be clear about what you've written between the lines: you have decided that impeding covert asicboost would be a violation of the "SegWit2x charter" and so you will assure that covert asicboost continues to function in your modified version of segwit and HF as people have been alleging you would do? This will require further departure and incompatibility with the segwit proposal.”

Infighting among Core members has continued on the topic of Bitcoin’s future following Barry Silbert’s attempt to ratify an agreement which would see SegWit introduction in September followed by a cooling-off period for a block size increase to 2 MB. Reactions have been mixed, while practicality problems on the Bitcoin network are resulting in greater user calls than ever to initiate a binding solution. Garzik, meanwhile, faced pressure to state whether he intends to have AsicBoost disabled. “Anything that was not discussed is, by definition, A New Issue To Raise And Discuss. Which is what was done here,” he wrote.

A New Zealand lawyer has called suspected pyramid scheme

We Grow Bitcoins a “simple scam” after a news investigation. In an article by local platform Newshub, consumer law specialist Prajna Moodley concluded that investors funneling money into the scheme, which promises 62 BTC ($148,300) monthly returns, would never see their cash again.

“I would go as so far as to say it's a simple scam, from what I can work this involves people investing money and never hearing from the company again," she told the publication. The investigation focuses on the story of a New Zealand investor by the name of Daniel Tepania, who sent the so-called “crowdfunding community” the required NZ$30 minimum entry fee and is awaiting payouts. "It's only been here about a month so I thought I would give it a go, sounded quite good," he told Newshub.

New Zealand’s Commerce Commission pointed journalists to its legislation on pyramid schemes when approached about We Grow Bitcoins, such schemes being illegal under local law. “WeGrowBitcoins is a member to member donation platform,” the website states. “Members pay a monthly subscription to have access to the platform. Platform access allows members to receive donations directly into their bitcoin wallet from other members.” Cointelegraph would like to remind readers that investing in projects purporting to deliver unproven profits in return for direct payment should be avoided.

Walmart Wants to Track Delivery Drones With Blockchain Tech

Retail giant Walmart is seeking to patent a system

that uses blockchain technology to track packages delivered by unmanned drones. The US Patent and Trademark Office (USPTO) published the application, innocuously titled "Unmanned Aerial Delivery to Secure Location", on 25th May, and while that title may not give away much of Walmart's plans, the application itself reveals further details. As outlined, the retailer is looking at blockchain tech as a way to track shipments that involve flying drones.

The patent application explains:

"In some embodiments, the delivery box may also include a delivery encryption system comprising a blockchain for package tracking and authentication. Package tracking by blockchain may include elements including but not limited to location, supply chain transition, authentication of the courier and customer, ambient temperature of the container, temperature of the product if available, acceptable thresholds for ambient temperature of the product, package contents placed in the container system (products & goods), or a combination thereof."

It's a notable release from the global retailer, which has revealed some of its work with blockchain in the past. For example, last October, Walmart announced that it was working with IBM to develop a supply chain solution focused on China’s pork market, the largest in the world.

At the time, the retailer indicated that it was looking to apply the tech to other supply chains. And while it provided no hint that it was looking at blockchain as an underlying mechanism for aerial drones, Walmart told CoinDesk that it wanted to leverage blockchain to facilitate "fresher and faster deliveries". The application also details how the tech could be used to establish identity within the package system. "Authentication and access may be restricted to specific blockchain keys to access the contents of a parcel's payload, and may include specific times and locations," the authors write. "Access to the contents may be determined at the scheduling and purchase of a delivery or products."

The recent ransomware saga is a potent reminder

of just how vulnerable our information and data is to cyber-threats. But it’s not just our information that’s vulnerable; these threats extend into the physical world of electricity as well. In fact, today’s electrical grid is incredibly insecure against cybersecurity threats; for example, the massive 2015 cyberattack on the Ukranian power grid that left 230,000 people in the dark and the intrinsic level of insecurity presented by smart meters used all over the world. And with billions of energy-using, Internet-connected devices expected to come online over the next decade (PDF), the grid is about to experience a several-orders-of-magnitude increase in the number of vulnerabilities to

cyber-threats.

As … billions of energy-using devices are integrated into the electricity system, malicious actors will see the potential to exploit these systems and attempt to usurp this new reality.

Fortunately, blockchain technology is inherently robust against cyber-threats, and many energy companies are considering how blockchains may bolster the grid’s cybersecurity. This is because blockchains are built for:

• Tamperproofing data (PDF): 
  Blockchains make it very difficult to change data after it has been written. This eliminates a number of risks, including man-in-the-middle attacks, in which a hacker modifies data that’s en route to its destination. With a proper blockchain implementation, all computation is "hashed" and made tamperproof at the point of origin, so there is no risk of data being modified while in transit.
• Disintermediation (PDF): 
  With blockchains, intermediaries (escrow corporations) often are no longer necessary, significantly reducing transaction costs.
• Complete data availability (PDF): 
  Blockchains can store data in a decentralized fashion across many nodes. With this architecture, even if some nodes or servers are compromised, users still can access a complete dataset.
• Redundancy (PDF): 
  Blockchains operate without a central point of failure, so reliability through redundancy is intrinsic to this architecture.
• Privacy and control: 
  Users of a blockchain can choose which data to make immutably transparent and which data to keep encrypted so only the intended recipients can view the contents.
• Outsourcing computation (PDF): 
  Encrypted data can be sent for processing to a third party, without the contents of the data being revealed.

As the world of energy becomes more digitized and decentralized, the need for solid defense against cybersecurity threats increases drastically. When a blockchain is implemented properly, it offers a strong defense against external and internal threats by mitigating internet-connected and data communications vulnerabilities, and increasing data confidentiality and privacy.

Mitigating vulnerabilities

Internet-connected energy-using devices have the most room for improvement when it comes to cybersecurity. Between January and April, the research found that over 2 million Internet of Things (IoT) devices in homes were hacked into and rendered useless (bricked). This attack was to protest manufacturers’ poor cybersecurity policies for the devices, chiefly, thousands of devices set by default to use basic login and authentication credentials (username=user and password=password). In this case, hackers could have been much more malicious than simply bricking devices, but they wanted to prove their point: Unsecured IoT devices are unsafe, and should not be allowed to operate in a real-world environment where people’s lives and property are at risk.

Blockchain technology and those working on making it more usable for everyone are paving the way toward a new user-authentication paradigm. The current system of username/password combinations has been obsolete for many years. A much more secure mode of authentication is that of the public–private key pair (also called public key cryptography), the default in systems such as Bitcoin and Ethereum. As these blockchain implementations become more user-friendly, we will see a natural evolution of all login systems toward this more modern and secure method.

With a properly integrated cryptographic key login system for blockchain-based applications, IoT device owners will bear a significantly reduced risk of loss of power, theft of data and threats to privacy. What's more, integrating pricing and settlement on wholesale electricity markets into a secure blockchain significantly minimizes the risk of false data injection and pricing manipulation. This is largely because of the tamperproof characteristic of blockchains, which ensures immutability of a given dataset or series of communications between transacting parties.

The blockchain is also relevant for addressing data privacy and security issues. As more data is collected and transported over the internet, the risk of data exploitation and breach increases, as evidenced by the release of confidential information from hacks of LinkedIn, Yahoo, Target and other large organizations. Blockchains allow for the encrypted transportation of private data, ensuring that data is readable only by the intended recipient.

Introducing a new risk: Key mismanagement

Blockchains are great at mitigating several cybersecurity risks, but they also introduce a new risk that is often overlooked: key mismanagement. Key management is the secure storage of digital keys in a fashion that prevents unauthorized access — something of significance for distributed energy resources, which eventually will be connected to the web and authenticated mostly through asymmetric cryptography (the method used for all blockchain-based transaction and authentication). Many early adopters of blockchain technology that don’t have a background in IT have lost their private keys, rendering their blockchain assets or devices inaccessible.

However, key management is getting some much-needed attention, and innovators are creating new ways to store and recover private keys securely. One innovative way to tackle this problem is to integrate key pairs in actual, physical devices (think key fobs for your car) and use them to activate devices. This minimizes, or in some implementations renders impossible, the risk of hackers accessing private keys that confirm the identity and authority of a signing entity. Keys that exist on a personal device enforce secure signing on, for example, an energy-using internet-connected device (an electric vehicle). For a malicious actor, if all signing must be on a device, then the physical device must be compromised in a way that allows a hacker to remotely execute commands on the device instead of just reading data, which is much more difficult for the hacker and therefore a more secure implementation.

As digitized and distributed systems in energy become more common and billions of energy-using devices are integrated into the electricity system, malicious actors will see the potential to exploit these systems and attempt to usurp this new reality. Therefore, it is paramount that we ditch the "build-then-patch" approach, and build systems integrated with holistic security. Fortunately, much of this security is inherent in a properly implemented blockchain.

A state-owned development bank in Russia

has revealed its plans for launching products built around blockchain. Vnesheconombank, an institution backed by the Russian government, is focusing its efforts on the areas of project management and supply chain finance, according to a report by Sputnik International. The publication quoted Vnesheconombank's chairman, Sergey Gorkov, who appeared this week at the St Petersburg International Economic Forum.

What they're doing: 
Gorkov's comments, as quoted, reveal a kind of two-prong approach: developing institutional knowledge and pursuing applications — trade finance in particular — that have captured the attention of a wide range of financial firms worldwide.

Here's how Gorkov framed the bank's project management initiative, according to Sputnik:

"When we started to think about how to manage projects efficiently, we realized that there is no platform. Everything that we had became obsolete. We realized that the blockchain is a good fundamental and qualitative platform for the future."

He said that the bank had since pursued a pilot project centered around the use case, with further iterations to follow. "We are launching the first prototype in terms of project management this fall," he told the publication.

Why it matters: 
That a state-backed bank in Russia is moving to launch services around the tech is a notable one — but perhaps not an altogether surprising one given the pace of blockchain development in the country's finance sector.

The unveiling comes months after Russia's prime minister, Dmitry Medvedev, called for more research into the tech by a pair of government agencies. Government officials also said earlier this year that they expect to develop blockchain-specific regulations, looking to an introduction by 2019. That work comes as Russia's central bank drafts new rules around bitcoin and digital currencies, with an eye to regulate them as kinds of digital goods.

Blockchain consortium R3 raises
$107 million

People may well remember 2017 as the year that blockchain broke.

After years of development and flickering just outside of mainstream consciousness and acceptance, record high prices for the most popular blockchain-based cryptocurrencies Bitcoin and newcomer Ethereum and an embrace of the technology’s core principles by some of the world’s largest institutions may mean that blockchain technology is ready for its close up. Nothing illustrates this more clearly than the just-announced $107 million financing for R3, the blockchain consortium that includes some of the largest financial services firms and technology companies in the world.

Leading investors included SBI Group, Bank of America Merrill Lynch, HSBC, Intel and Temasek, the company said in a statement. R3 represents the largest consortium of global financial institutions working on developing commercial applications for the distributed ledger technology that’s at the heart of blockchain technology. In addition to the big names that committed the most capital, R3 pulled in additional commitments from ING, Banco Bradesco, Itaü Unibanco, Natixis, Barclays, UBS and Wells Fargo.

R3, which opened the first tranches of the company’s planned $200 million financing exclusively to members of the consortium, is one standard-bearer for the mainstreaming of blockchain technology. Indeed, the company already counts among its customers the government of Singapore, the Bank of Canada and other national financial institutions. The company said it will use the funds to accelerate technology development and grow strategic partnerships for project deployment. R3 has its own proprietary ledger that can be used to develop applications, and it also supports an infrastructure network for financial services firms and technology companies to build their own ledger-based applications and services.

“While still in its infancy stages, the emergence of distributed ledger technology comes at a time when the financial services industry is poised to further embrace technological change and efficiencies,” said C. Thomas Richardson, the managing director and head of market structure and electronic trading services at Wells Fargo Securities, in a statement.  That sentiment was echoed by other financial services executives whose firms were members of the R3 consortium. “Innovation in digital technologies is reshaping the banking industry, and this investment is reflective of our belief that distributed ledger technology and smart contracts have the potential to significantly enhance capital markets infrastructure. R3’s collaborative approach is key to the progress of this technology,” said Andrew Challis, managing director of strategic investments at Barclays.

Not all big banks and financial services firms have embraced R3. Goldman Sachs and Santander both dropped out of the consortium, perhaps figuring they’d be better off going their own way. Where R3 has really shined has been in getting governments comfortable blockchain-based applications. Their approach of enlisting banks and financial services companies for projects is light years from the more subversive mindset of some of the developers of the original and the largest blockchain protocol, Bitcoin.

As some investors and entrepreneurs see it, there’s room in the market for both the private blockchains developed by communities around Bitcoin and Ethereum, and the sanctioned corporate ledgers that companies like R3 are developing. For now, the technology that R3 is developing is focused on business applications like verifying transactions between banks, or automating the things like the establishment of the London Interbank Offer Rates. In the future, the company’s technologies could touch consumers more directly — through the creation of a digital fiat currency. While that may be somewhere far off down the horizon, with the company’s connections to the banking industry and to national governments, it’s not beyond the pale.

Eight Reasons To Be Skeptical About Blockchain

Given the turbulent, even frothy environment for disruptive digital technologies, one novel entrant promises to be among the frothiest: blockchain. The secure distributed ledger technology behind Bitcoin, blockchain has exploded out of the realm of the dubious cryptocurrency into a hype-driven category of its own. VC money is pouring into numerous blockchain startups. IBM IBM +0.59% is betting the farm on the technology. Pundits around the globe are calling for blockchain to reinvent everything from equities trading to charitable giving. And yet, aside from Bitcoin itself, real-world implementations of blockchain are few and far between. Has the hype exceeded the reality?

Let’s see what a number of skeptics have to say.
 

  

Secure ledger from an earlier century

Blockchain is a Solution Looking for a Problem

As blockchain exploded from its cryptocurrency roots, it quickly took on new life, as proponents rushed to figure out what else it was good for. “‘Blockchain is a solution looking for a problem’ is a sentiment that we heard several times while conducting this research—a fair representation of the reality,” says Axel Pierron, founder and managing director of financial consulting firm Optimas LLC. “Rather than investing in ‘catch all’ blockchain-related initiatives, the industry should focus its attention on evaluating the various solutions that can address the issues that need to be solved.”

The Open Data Institute also warns about selecting the ‘right tool for the job.’ “We think that the government should go further and think about how it can convene sectors (such as finance, agriculture, or health care), identify common challenges in those sectors and then determine which technology approaches — whether blockchains or not — are the most appropriate in helping to address them,” the ODI blogs. “Blockchain technology is a new tool in our toolbox. We need to use it when it is the right tool for the job at hand.” (Emphasis in both paragraphs is theirs.)

End-Users Don’t Really Want to Use Blockchain

It’s difficult enough to use Bitcoin for any day-to-day task, let alone blockchain. “But still, eight years after Bitcoin launched, Satoshi Nakamoto remains the only creator to have built a blockchain that an appreciable number of ordinary people actually want to use,” opines software engineer Jon Evans, principal at HappyFunCorp and columnist for TechCrunch. “No other blockchain-based software initiative seems to be at any real risk of hockey-sticking into general recognition, much less general usage.”

Perhaps a proof of concept would help? Blockchain aficionados have implemented an online trading card game they call the Rare Pepe Game to explore the potential of the technology. Even this simple example, however, proves wanting. “[The Rare Pepe Game] also shows how a game can be built on a blockchain with virtual goods and characters and more,” explains Fred Wilson, managing partner at Union Square Ventures. “And it shows how clunky this stuff is for the average person to use. Just playing around with this over the last few days showcases to me all of the technical challenges that blockchain technology still has to overcome before it can become mainstream.”

Blockchain Will Increase Transaction Costs

By disintermediating financial institutions, so the reasoning goes, multiple parties can conduct transactions seamlessly, without paying a commission. However, cost savings are dubious. “Moving cash equity markets to a blockchain infrastructure would drive a significant increase of the overall transaction cost,” Pierron continues. “Trading on a blockchain system would also be slower than traders would tolerate, and mistakes might be irreversible, potentially bringing huge losses.”

Unlikelihood of Sufficient Adoption

The promise of blockchain in large part depends upon enough parties using the same implementation of the technology — a classic example of the network effect. However, it’s unclear any particular blockchain solution (other than Bitcoin itself) will ever be able to reach this threshold. Without such universal adoption, blockchain’s practicality is questionable. “It’s obvious that a credit union-only distributed ledger system will require universal adoption to be of any use,” says John San Filippo, cofounder and principal at OmniChannel Communications. “It’s my experience that trying to achieve universal adoption of anything in this industry is an act of pure futility.”

Blockchain is Too Complicated

The technology behind blockchain is complex enough. Add it to the complexity of a heavily regulated business environment, and blockchain may not even get out of the gate. “Blockchain is thus also turning out to be more complicated than most of us thought,” warns Kris Henley, communications manager with the Centre for the Digital Economy at the University of Surrey. “Its tremendous potential is mitigated by its steadfast resistance to being a ‘magic’ solution, and its need for regulation like so many game-changing technologies of the Digital Economy.” Optimas’ Pierron chimes in as well. “Processing trades via blockchain would not simplify the capital markets, but rather move the complexity around,” he adds.

Performance Issues

Because of its inherently distributed, peer-to-peer nature, blockchain-based transactions can only complete when all parties update their respective ledgers — a process that might take hours. As ledgers grow, furthermore, people question whether they will bog down. “Blockchain has a lot to prove in its performance,” says Peter Hiom, deputy CEO at the ASX trading exchange. The transaction delay may also be a deal-killer. “The delay before the final assurance that a transaction has been recorded ‘for good,’ that can be up to a couple of hours, would create too much uncertainty for market participants, especially during time of high volatility,” continues Pierron.

Blockchain Ledgers’ Immutability Isn’t Always a Good Thing

One of blockchain’s most touted benefits is the immutability of its ledgers: once participants record a transaction, no one can change or delete it. Such immutability prevents the correction of mistakes to be sure — but there are other issues as well. In fact, immutability may cause blockchain to run afoul of regulation. “Digital ledger technologies must be chosen based on user needs and legal requirements,” writes the Open Data Institute. “For example; tamper-proof and immutable data stores prevent the modification of stored data, but this may not always be an acceptable property. The EU ‘right to be forgotten’ requires the complete removal of information; if that data is in an unchangeable system like a blockchain, this could be impossible.”

Blockchain is a ‘Trojan Horse,’
Sent by Radical Libertarians to Undermine the Global Financial System

Take this one with a large grain of salt to be sure — but at least one Bitcoin entrepreneur has stated this position. “I have no problem with the financial industry inviting the Trojan Horse of blockchain technology into their walled garden because I know how powerful the technology is,” says Erik Voorhees, CEO, and founder of cryptocurrency startup ShapeShift.io. I’ve warned about the Libertarian context for Bitcoin before, but if any members of this devoted but misguided group believe that blockchain alone will disrupt the financial industry, they are out of touch with how cautious the industry is.

In fact, the more likely blockchain is to disrupt the global financial system, the less likely it is to succeed. For disruption to be a positive business force, it must drive new competitive advantage, not simple chaos. Blockchain may be disruptive, but it’s still an open question whether it’s too disruptive for its own good.

Critical Social Strategy Mistakes to Avoid

Businesses fail at social media marketing for so many reasons, but more often than not, it is due to weak strategy

The Rules of Social Media Marketing Success:
Leadership and Community

What kind of leader do you think will inspire a social media marketing team?

Rome wasn't built in a day and neither is social media marketing success. It takes a combination of strategy, relationship building, trust, planning and more for a brand to capture an audience's attention and further, make them take action. This is the third in a four-part series. We've previously delved into the importance of listening and planning and the need to build relationships and trust. Today we're going to look at the role that leadership and community play in creating long-term success.

Demonstrate Leadership

Social media leaders — as is the case with their offline counterparts — are valued and respected for their knowledge, experience, passion and vision. The most effective social media leaders also demonstrate a strong sense of responsibility, serve as standard bearers, have a relatively high tolerance for risk, lead by example, think strategically, plan for the short- and long-term, express humility, and have the ability to inspire others. Another important characteristic synonymous with social media leadership is integrity. And because of the ability for others to quickly and easily spot insincerity and dishonesty on social media, a leader's integrity must be rock solid at all times. 

Innovation is another hallmark of a strong leader. The most successful leaders on social media not only create new concepts and trends and serve as change agents, they also figure out unique ways to generate value and generously and consistently share that value with their online communities. Are you an influencer? Every effective social media leader is. In fact, many of their friends and followers are subconsciously looking to be influenced. It's how they learn. And that's why they keep coming back to the leaders for guidance and inspiration.

Finally, what about leadership style? Think about those leaders you know who are akin to a tyrant, ruling by dictate. Or the other ones you know who are compassionate but have a firm hand on their ship's tiller and wise words of advice for their shipmates. Which approach do you think has the most impact in the social media world? Demonstrating leadership is probably the fastest way to create a loyal following on social media. But along with that comes responsibility. So take it seriously.

Build Community

Building a loyal community of fans and followers is not a snap-your-fingers and you're done deal. You have to put effort into attracting and growing an audience, and you’ll have to continually nurture the crop before it bears any fruit. But the payoff for that investment can be significant. Where to begin? Start by identifying key influencers and cultivating individual relationships with them that you can later aggregate into a group of people who share common interests. This is your foundation — the heartbeat of your social media marketing activity. These relationships will become the core of your community and will help you expand its reach and contribute to its growth and influence.

The key to aggregation is providing quality content to your community that interests your target audience — content that’s informational in nature, not a sales pitch. And make sure that content is always relevant to your strategy and your followers. Effective connections with your audience are built when you provide information that’s based on understanding your market segment and your community’s needs, and by presenting those relevant morsels in a concise, easy-to-digest way.

And make it easy for your community members to share your content with their other communities. This will help dramatically expand your reach. Also, you don’t have to create all the content yourself. Instead, promote the submission of user content from within your community, so everyone who wants to get involved is able to do so. Yes, community building can be difficult, mainly because it requires determination, dedication, and grit — and a lot of time. But it’s key to your longevity in social media.
