nChain Releases Nakasendo™ Software Development Kit

LONDON, April 16, 2018 /PRNewswire/ — nChain, the global leader in research and development of blockchain technologies, is pleased announce that it has completed version 1.0 of its new Nakasendo™ software development kit (SDK).  The SDK is being made available now to selected partners in an initial testing pool, and will be made available more publicly at a later time.

The SDK is named after an ancient trail connecting Edo (modern day Tokyo) to Kyoto; in Japanese language, “nakasendo” means “road through the middle mountains” or “central mountain route.”    Through its Nakasendo™ SDK, nChain will provide software libraries that help application developers navigate the complexities of blockchain development, and accelerate their work to make blockchain technologies used by major enterprises across the globe.

Version 1.0 of the SDK focuses on providing a cryptographic library, to allow for a more flexible method of key generation and sharing.  This cryptographic library can be used to improve security for any cryptocurrency exchange, and more broadly for controlling access to any type of digital asset or resource.  It incorporates these two patent-pending assets from nChain’s intellectual property portfolio:

  • WO2017145016 (Deterministic Key Generation): “Determining a common secret for the secure exchange of information and hierarchical deterministic cryptographic keys” provides a method whereby two connected nodes, with no trust relationship between them can derive a deterministic hierarchy of each other’s public keys through simply sharing their respective public keys and a message of some format, where the respective private keys can still only be generated by the owner of that private key. Further information on this method can be found on nChain’s website at https://nchain.com/en/blog/nchains-security-inventions/
  • WO201714510 (Secure Split Key technique): “Secure Multiparty loss resistant Storage and Transfer of Cryptographic Keys for blockchain based systems in conjunction with a wallet management system” provides a method derived from, but distinct to, “Shamir’s secret sharing scheme” whereby a key can be split into multiple shares and then, in conjunction with the method defined in WO2017145016 above, these parts can be shared using a common encryption key. Further information on this method can be found on nChain’s website at https://nchain.com/en/blog/nchains-security-inventions/

Both of these patent-pending innovations can provide significant security benefits to prevent “Mt. Gox-type” hacks of cryptocurrency wallets.  They can also be used far beyond Bitcoin and blockchain environments – for any situation in which sensitive data, assets, communications or controlled resources need to be secured.  nChain Chief Scientist Dr. Craig Wright is a key inventor for these two assets.

nChain is providing the Nakasendo™ SDK for use under a newly-created “nChain Open Bitcoin Cash License.”  This Open Bitcoin Cash License allows royalty-free usage of copyrights to software in the SDK libraries, and any associated patents that read directly on such software – but only for users to create software or applications that operate on the Bitcoin Cash (BCH) blockchain.   nChain’s license is modelled after the Microsoft Limited Public License, which provides free right to use certain Microsoft software to create works that run on a Microsoft Windows operating system product.  Just like Microsoft’s Limited Public License has a platform limitation for free usage, nChain’s license limits free usage to the Bitcoin Cash blockchain.

nChain Group’s CEO Jimmy Nguyen explains:

“We are excited to reach this milestone with the Nakasendo™ SDK, which will help developers navigate the mountains of blockchain work. Although the SDK libraries will be useful for developers on any blockchain or digital platform, we want to use key elements of nChain’s patent portfolio to help benefit the Bitcoin Cash ecosystem.  That is why we are providing the SDK for free usage only for applications and products that operate on the Bitcoin Cash (BCH) blockchain.  The SDK is one of many tools nChain will use to ignite the BCH blockchain, and help re-invent the business world.”

nChain aims to continue development of its Nakasendo™ library to incorporate further cryptographic techniques and other blockchain optimisations in future releases.

If you are interested in receiving access to the Nakasendo™ SDK when it is more publicly released, please send an email to contact@nchain.com.

Hanergy Unveils Next Generation Hantile Solution

Company’s new solar-embedded roof tile once again sets the standard for energy efficient buildings

BEIJING, April 15, 2018 /PRNewswire/ — Hanergy today introduced a new generation of its flagship Hantile building product that is lighter, thinner, more flexible, and features superior performance. The new Hantile combines Hanergy’s world-leading flexible thin-film solar panels with high-transmittance glass to create an innovative product capable of high-efficiency power generation that can fully replace traditional roof tiles. Hantile makes ultra-low-energy buildings and even net-zero energy buildings possible, reducing or eliminating dependence on traditional energy sources.

“We’re delighted to introduce the next generation of our innovative Hantile building solution,” said Hanergy founder Mr. Li Hejun. “With its industry leading energy generation capabilities and suitability for any building, I am confident that Hantile will set a new benchmark for new energy applications in building construction.”

The new Hantile features a single rather than double layer of glass with each tile weighing only 5.2 kilograms. Combined with its unique C-type slot structure, Hantile’s light-weight greatly improves ease of installation. With Hantile, Hanergy has pioneered the use of ultra-white tempered glass, which features a transmittance level of 91.5%, and possesses extreme durability and ability to withstand heavy impacts. The single glass Hantile is also highly wind resistant and able to generate power at temperatures ranging from -40 to -85 degrees Celsius, and humidity higher than 85%. Hantile features a life cycle of up to 30 years, longer than traditional roof tiles.

In terms of environmental value, the estimated environmental value of each 25W watts of Hantile is equivalent to planting a single tree.  The 100 square meters of Hantile is equivalent to planting 340 trees

Hanergy’s ability to achieve such a major upgrade in less than a year is a result of its continuous technological innovation. In the past year, Hanergy has achieved 3 world records in the R&D and mass production efficiency of thin-film chips: the efficiency of its GaAs single-junction mass production modules has reached 25.1%; the total area efficiency its of copper-indium-gallium-selenium (CIGS) glass-based modules has reached 17.52%; and the efficiency of its flexible sputtering components has reached 17.88%. All have been certified by international authorities as the latest world records.

Hanergy currently has more than 2,300 patents worldwide.

As Drought Keeps Men on the Road, Mauritania’s Pastoralist Women Take Charge

Every year when the pastoralist men in Fatima Demba’s Mauritanian village return from their months-long journey to find pastures and water, the women erupt in wild celebrations.

“We draw henna tattoos on our bodies, we braid our hair, we wear our nicest clothes,” she said, re-adjusting her bright yellow and blue robe.

Yet although she longs for her husband to come home, Demba sees one benefit in his absence.

“I am in charge of everything,” she told the Thomson Foundation, sitting in the shade of a mud-brick hut in Mafoundou village. “Our money, our field of millet � even the village’s borehole is my responsibility.”

Prolonged dry spells in this southern region of Mauritania have depleted grazing land, forcing pastoralists to travel ever longer distances to search for food and water for their herds.

That gives women in these predominantly male-dominated societies newfound power to manage harvests, the family’s remaining animals and household finances, experts say.

“Women pastoralists are the first up in the morning and the last to go to bed at night,” said Aminetou Mint Maouloud, who started the country’s first association of women herders in 2014.

“Whether it’s making butter from cow milk, fetching wood or tending to ill animals, it all comes down to women,” she added.

Worsening Drought

Livestock herding is a traditional way of making a living in West Africa’s Sahel, a semi-arid belt below the Sahara, but herders have become increasingly vulnerable to food insecurity as climate change disrupts rain patterns in the region.

That is particularly true in the impoverished desert nation of Mauritania, according to El Hacen Ould Taleb, head of the Groupement National des Associations Pastorales (GNAP), a charity working with pastoralists.

“Transhumance � the seasonal migration of pastoralists and their herds to neighboring Senegal or Mali � normally starts in October but the rains were so bad last year that people started leaving in August,” he said.

His organization is helping pastoralists find smarter migration routes � with water sources and markets along the way, for example � as part of the British government-funded Building Resilience and Adaptation to Climate Extremes and Disasters (BRACED) program.

Demba, whose husband has been gone for seven months, says she does not know when he will return.

“He has no choice, he must save our animals,” she said, pausing to take a sip of a glass of green mint tea.

In the meantime, “the family depends on me,” she added.

Under-recognized

Although women play a crucial role in pastoralism, it is rarely acknowledged, according to Mint Maouloud.

“A man will listen to everything his wife whispers on the pillow, but in the morning she won’t get any credit for it,” she said.

To change that, her association has elected a council of eight women from villages around the country. Together they lobby the country’s government on pastoralism issues.

“We tell them where an animal clinic might be needed, or which markets are best for specific kinds of animals,” she explained.

Their suggestions could find an unusually understanding ear.

Since Mauritania’s livestock ministry was created in 2014, both of its leaders have been women.

Vatma Vall Mint Soueina, the current minister, says women seeking political roles is “extremely encouraging” � and that she has seen women grow in economic clout.

“We are seeing women becoming more independent, by virtue of being so active economically,” she said from her office in Nouakchott, the capital.

Financial Independence

In Hadad village, amid stretches of sand and dirt dotted with the odd wilting tree, a dozen women huddle under a large tent covered with striped rugs.

Mariem Mint Lessiyad, a tiny woman with piercing brown eyes, chats energetically to the group, interrupted only by a bleating baby goat.

She leads a cooperative of 100 pastoralist women from nearby villages who buy chickens and sheep to raise and slaughter, selling affordable portions to local families.

“There is less meat going around, so we need to be clever with how we consume it,” she said.

The women buy a sheep for 12,000 Mauritanian ouguiya ($34), for instance, and make a profit of about 2,000 ouguiya ($6) per animal, she said.

They plan to reinvest the surplus in setting up a leather goods business.

“We can’t rely on our husbands to support us financially. They are too poor, especially now that they have to spend more money on keeping our animals healthy,” Mint Lessiyad said.

Mint Maouloud and her association are trying to persuade financial institutions to make it easier for women to get loans, so groups like Mint Lessiyad’s can get ahead.

Access to finance can be problematic, she said, with some banks outright refusing to lend money to women.

“It’s important to make women herders more independent financially, so they don’t rely on their husbands’ generosity or understanding,” she added.
