Nasdaq Blockchain to build a Solar Energy Market

energy_blockchain_projects
Today, during an event organized by Nasdaq, the well-known stock exchange announced its new service that allows solar power providers to sell certificates using its Linq blockchain.
This special solar panels are linked to the Internet connection through a technology created by Filament, a Nevada blockchain startup that built a system able to connect traditional devices to the internet.
Thanks to the Nasdaq private blockchain called Linq, it is possible to create certificates that can be purchased by anyone who wants to finance the solar energy.
Even if there were a couple of bugs, the resultant certificate appeared on the screen during the live video demonstration. 
During an interview conducted by Coindesk, Alexander Zinder, director of the global software development at Nasdaq, cleared up how this new technology works.
“The solar panel is actually hard-wired into the IoT device through a converter which enables us to measure the wattage they’re putting out and producing into the grid.”
This innovative project was born thanks to a partnership between Nasdaq and IDEO’s CoLab.
“We think it’s a very compelling use case, but there’s a lot of opportunity, but it’s extremely early in our exploration”, continued Zinder.

Blockchain and energy: Usizo

This is not the first time we hear about a project related to energy and the blockchain.
A few months ago, in fact, we talked about Usizo, a crowdfunding company who is trying to improve energy payments between users and schools in the African country. 
Usizo works thanks to a smart meter that accept digital currencies and through a crowdfunding platform where people can donate their bitcoin. 
Donators can see the electricity needed by a school and can know how much he will contribute based on the BTC he donates.


Ethereum used for Car Charging

Also, a German power company, RWE, started a partnership with the Ethereum-based startup Slock.it, to develop proofs-of-concepts using the Ethereum blockchain.
RWE Carsten Stöcker commented:

“We would like to solve the problems and really push electric vehicle deployment forward by looking into establishing a seamless and affordable electrical charging infrastructure.”


How to pay energy with Ethereum

An American resident used the Ethereum blockchain to sell energy to his neighbors.
The two men did the transaction through the LO3, a startup that aims at changing the energy industry. 
Lawrence Orsini, founder at LO3, explained that his startup wants to show how people can use the blockchain on a daily basis to facilitate their peer-to-peer exchange.

Ethereum Used for Paid Energy

An American resident used the Ethereum blockchain to sell energy to his neighbors.
The two men did the transaction through the LO3, a startup that aims at changing the energy industry. 
Lawrence Orsini, founder at LO3, explained that his startup wants to show how people can use the blockchain daily to facilitate their peer-to-peer exchange.
During an intereview with Coindesk, Orsini commented:
“All the projects that we’re working on are squarely focused on the emerging distributed economy, peer to peer concepts. They’re all squarely focused on distributing and decentralizing assets into communities, into people’s hands, the new economy of the future.”
Thanks to LO3 and ConsenSys, the American resident Eric Frumin had the chance to sell renewable energy directly to Bob Sauchelli, the former program manager at EnergyStar
The energy created by Frumin’s solar panel is tracked on the blockchain. 
Sauchelli commented:
“With this arrangement, I’m going to pay him the whole premium, it won’t cost me anymore. I’m going to pay him what I’d pay the power company, but he’s going to get the whole premium, not just the wholesale rate”.

Bitcoin for Electricity

It’s not the first time we hear about electricity sold for cryptocurrencies and tracked through the blockchain.
In fact, during the MIT Enterprise Forum of Cambridge it was presented a new startup called Usizo, a crowdfunding company who is trying to improve energy payments between users and schools in the African country.

Bitcoin can win the competition with Fiat currency

Some days ago the researchers of the Federal Reserve Bank of Philadelphia released a new whitepaper in which they explained that bitcoin and digital currencies can win the competition with Fiat currency, or the government money.
On April 3rd, in fact, Jesus Fernandez-Villaverde of the University of Pennsylviania and Daniel Sanches of the Bank of Philadelphia published an interesting paper that answers the question: “can competition among privately issued fiat currencies such as Bitcoin or Ethereum work?”.

Bitcoin vs Fiat 

In this whitepaper Villaverde and Sanches try to explain how private and digital forms of money can interact (and could win the competition) with government-issued money.
To comment about this topic, the authors talked about the rise of the Internet, thanks to it, in fact, digital currencies such as Bitcoin or Ethereum can stand out in the competition with Fiat.
This is a comment of the whitepaper’s authors:
“Our model highlights how the issuing of a private currency is logically separated from banking. Both tasks were historically linked for logistical reasons: banks had a central location in the network of payments that made it easy for them to introduce currency in circulation”.

HolyTransaction Bitcoin Roundup March 2016

Welcome to HolyTransaction’s third monthly recap for the new year of 2016. This past month of March has been marked by continued interest in blockchain from everywhere; during that time, the bitcoin price rose from a high of $435.23 on March 1st to a low of $414.66 on March 31st, according to Bitcoin exchange Bitstamp.

It’s time to Blockchain-ize things like sneakers with Chronicled

A new blockchain startup, Chronicled, is planning to blockchain-ize the growing multi billion dollar industry that is sneakers. The company has raised $3.4 million on Crunchbase for its mission. The phenomenon of thousand dollar shoes for the male market has somewhat been predicted by similar economic pressures in shoes for females. Chronicled will use the blockchain to bring accountability and cleaner profits to this and other similarly affected industries.

Even Disney wants a piece of the blockchain action

The most recent surprise blockchain job opening is from Disney. While the corporate giant has many diversified products, this is a prime example of blockchain technology’s ability to help any company save in the middle and back office. Disney also probably has an interest in forever securing their rights via multiple blockchains.

VISA is planning its own blockchain for internal use. They are hiring an engineer/developer to help them and are also working with Chain.com. VISA believes that this area will have a critical impact on the future of the industry and wants to get ahead of the curve. Other companies from around the world that are creating blockchain labs and teams include Hitachi, Phillips, and even Walt Disney.

Ethereum’s newest version, Homestead, has officially launched. The price of ether was very volatile around the release of this software as new users rushed in. Homestead replaces Frontier, and allows users to begin using the smart contract technology. Already, companies are being built around the Ethereum blockchain.

Smart Contracts through Rootstock, Ethereum and Bitcoin thanks to RSK Labs

smart contracts bitcoin ethereum blockchain
Some days ago Rootstock received $1m in seed funding for its own blockchain startup called RSK Labs who provides smart contracts through the bitcoin distributed ledger and compatible with the Ethereum platform.
The funding came from the bitcoin mining company Bitmain Technology and from the bitcoin companies Coinsilium and Digital Currency Group (DCG).
During a recent interview, Diego Gutierrez Zaldivar, CEO at RSK Labs, commented they aim at building a blockchain platform for bitcoin miners and for developers.
Zaldivar said to CoinDesk:
“Our idea is to leverage everything that has been built by the community so far. Not only on the network effect of bitcoin, because the miners will have an additional revenue stream by merge-mining Rootstock, but by providing Ethereum developers a place to build their applications.”
Probably RSK Labs will launch its platform within the end of 2016. 


Smart contracts with the Blockchain

Even if the RSK Labs is very good news, the most important thing we can learn from this event is the interesting development of contracts managed through the blockchain. 
Smart contracts were originally proposed 20 years ago by the famous cryptographer Nick Szabo
A decentralized blockchain with smart contract applications can allow a global financial inclusion, new democratic political systems and the improve of the Internet of things. 
In fact, smart contracts are technology protocols that verify and ease the stipulation of a contract. 
This way smart contracts can provide a better security compared to a traditional contract and allow a significant reduction in transaction fees. Also, smart contracts can provide a service with less risks and without central counterparties. 
To know more about smart contracts and RSK, read this article.

Ethereum and Arcade City could kill Uber

A few days ago Don Tapscott suggested the idea that the blockchain could cause the death of services like Uber and Airbnb.
And it seems like this is truly happening, as a service called Arcade City has officially published a press release where they “declare war on Uber over fare cuts and plan to replace drivers with self-driving cars”.

Arcade City is an open marketplace where riders connect directly with drivers. It only works via a mobile app, available for both iOS and Android. 

How it works

Let the company speaks for itself:

It works through the Ethereum Blockchain

Most importantly, Arcade City integrates the Ethereum blockchain.
During a recent interview with CoinTelegraph, Christopher David, founder at Arcade City, commented: 

“the main deciding factor was that the vision of Ethereum aligns precisely with our own vision of peer-to-peer transportation and distributed logistics”.

Where can we move with Arcade City?

At the moment Arcade City is active in the US.
These are the states: Arizona, Arkansas, California, Colorado, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maryland, Michigan, Minnesota, New Mexico, North Carolina, New Hampshire, New Jersey, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Virginia, Washington and Washington D.C.
Drivers are also available in Australia; while Mexico, Canada and Sweden will be launched next spring.

Ethereum Launches Homestead

Blockchain project Ethereum has just launched Homestead, the first release of its software implemented at block 1,150,000.
ethereum launches homestead, homestead release
This new implementation comes at a time when more and more financial institutions and startups are revealing their interest in Ethereum and in creating projects related to the blockchain. 

Just a few days ago, in fact, we talked about how Ethereum now is bigger than ever

Special advisor at Ethereum Foundation, William Mougayar, explained that Ethereum processes almost 25,000 transactions per day: about 10% of the number of Bitcoin.

“You need to look at the growth of the Ethereum network via the growth of its nodes, sitting at 5,100 versus bitcoin’s about 6,000 roughly. That’s quite significant and shows the stability and global nature of the Ethereum network,” commented Mougayar.



Homestead vs Frontier

Homested is preceded by Frontier, that was released in July 2015. 
Co-founder of ConsenSys Enterprise, Andrew Key, commented that Homestead will help users to expand their possibility on Ethereum and the simplicity that will allow them to be able to build proof-of-concept products.
Keys said to CoinDesk:

“Homestead’s arrival will begin to demonstrate the next generation of blockchain technology, whereby anything we can dream of, can be accomplished in a decentralized manner using Ethereum.”





“We’ve seen Microsoft and IBM doing projects on Ethereum. There’s a lot of coders. It’s exciting to see something you were in on in the early stages growing and bearing fruit,” said Ethereum co-founder Anthony Di Iorio.


Ethereum helps Car Charging

In Germany the startup called Slock is working with RWE on a project to use Ethereum for car charging uses.

This project debuted at the Lift 2016 conference in Geneva, Switzerland and it will play out within 2017.
According to the RWE, customers will use charging stations by accepting a smart contract programmed on the Ethereum blockchain.

Ethereum used for Car Charging in Germany

A German power company, RWE, started a partnership with the Ethereum-based startup Slock.it, to develop proofs-of-concepts (POCs) using the Eth blockchain.

Germany supports green power

On May 2011 the German Environment Minister Norbert Rottgen announced the government’s decision to close all the nuclear power plants within 2022.
During an interview conducted by the BBC, in fact, Mr Rottgen commented: 

It’s definite. The latest end for the last three nuclear power plants is 2022. There will be no clause for revision.”
So, RWE, company who provides coal and nuclear energy infrastructures in Germany, has now decided to invest money in a new sustainable energy and in an Ethereum project to reduce expenses.
To do so, RWE created a working team to test the blockchain technology to aim at trim costs by lowering expenses related to energy transmission.

Car Charging with Smart Contracts

In a recent interview conducted by CoinDesk, RWE Carsten Stöcker commented on a possible application of the blockchain: electric car charging stations that use smart contracts to authenticate users and manage the billing process.
“We would like to solve the problems and really push electric vehicle deployment forward by looking into establishing a seamless and affordable electrical charging infrastructure.”
This project debuted at the Lift 2016 conference in Geneva, Switzerland and it will play out within 2017.
According the RWE project, customers will use charging stations by accepting a smart contract programmed on the Ethereum blockchain.
Through this system users will save money thanks to a payment that is connected to the consuption of electricity during the charging, instead of paying according to the time connected to the station.

“What’s really exciting here is that people are going to be able to use smart contracts to contract with a machine directly, rather than contracting with a human being or a corporation,” he said to CoinDesk.

Ethereum is bigger than ever

During the past months cryptocurrency Ethereum was growing fast, increasing its value and consequently its own popularity.
Today the Ethereum price is about $9 (0.022 BTC) and it undergone very few changes with an almost always upward price.
Just in the last day Ethereum raised its market capitalization by 26%, reaching almost $730 million, representing more than 10% of Bitcoin’s market cap.
This behaviour is truly important as Ethereum is proving to be much louder than the other altcoins, reaching the market capitalization of all the other altcoinsll together, excluding bitcoin.

Microsoft Corporation certified Ethereum

Some days ago a startup who provides Ethereum softwares, BlockApps became the first certified company on Microsoft Azure’s Blockchain-as-a-Service (BaaS).
Director of Blockchain strategy at Microsoft Corporation, Marley Gray, commented:
“The simple, rapid and flexible one-click deploy of Ethereum blockchain architecture launched on the Microsoft Azure Marketplace enables enterprises and developers to quickly deploy a certified blockchain environment on Azure.”

But, what is Ethereum?

Created in 2013 by Vitalik Buterin, Ethereum is a cryptocurrency and a blockchain platform who provides decentralized services.
  At the moment Ethereum is in the so-called Homestead phase, the second of the six phases of its rollout that they company planned. The other phases will be “Metropolis (Mist release), Serenity (proof of stake Casper plus abstraction, aka Ethereum 1.5), Ethereum 2.0 and Ethereum 3.0 that will focus on scalability”, commented Buterin during a recent interview conducted by Bitcoin.com.
Thanks to Homestead, said Buterin, “the risk of using the Ethereum platform is now substantially reduced”.

‘We’re All in on Blockchain’, says IBM

We are all in on Blockchain”: these were the words of IBM Director John Wolpert during the today Blockchain Conference in San Francisco. According to Wolpert the blockchain needs a more collaborative approach, which is not always guaranteed by the blockchain developers. 

So it seems that the worldwide company IBM wants to ensure itself a leading role in the market solutions related to the blockchain.

In fact, IBM is working on the Hyperledger Project, an open-source blockchain led by The Linux Foundation. Presented in December, this project stars thirty companies including ABN Amro, CME Group, Red Hat and several blockchain startups.
“It’s amazing how many smart and genius people are behind bitcoin, but they miss some logic here. You don’t need to go from trusted to trustless on everything. I think that’s an honest disagreement. The Internet is a permissioned walled garden. Anyone heard of ICAAN [Internet Corporation for Assigned Names and Numbers]? It’s permissive, but it’s permissioned”, said Wolpert. 
Hyperledger Project’s goal, he continued, is to be an evolution of the first generation projects such as Bitcoin and Ethereum, that gather all the best projects that leverage on the blockchain together with all the stakeholders that will potentially use such technology. This is necessary if we want to have a widely used transactional protocol.
It has to be immutable and modular. It can’t be this is the consensus algorithm, this is the token, all of that has to be modular. It has to be scalable. Interledger-ing is important. You have to inter-op between chains and different things”, he said.
During his speech Wolpert also emphasized IBM’s experience in consensus algorithms and distributed computing during the last 30 years. 
It’s thanks to such experience that IBM was able to conduct the Hyperledger Project, that Wolpert sees as the only way to bring all the different stakeholders to the same table and make them work together to build and open-source blockchain platform that can be used in many different areas, as it is for Linux.
We’ve been doing projects on every kind of blockchain. We’ve been doing that for a couple years and now we have a whole unit. We announced [we worked with] the Linux Foundation […] At that point, we went all in on blockchain”.
