Blockchain data platform Streamr is partnering with Finnish telecom giant Nokia and California software company OSIsoft to allow mobile customers to monetize their user data and make purchases.
Chief executive Henri Pihkala announced the partnerships at CoinDesk’s Consensus 2018 conference Wednesday, while also conducting a live launch of its real-time data marketplace, through which users can provide and subscribe to real-time data streams.
He said in a statement that “today marks a hugely significant day in Streamr’s history, not only showcasing our platform to the world on-stage at Consensus but announcing two stellar partnerships.”
The partnership with Nokia will see Nokia’s Kuha base stations integrate with Streamr’s data marketplace, allowing Nokia customers to both monetize their user data and purchase streams from Internet of Things devices.
Smart contracts are a transformative new technology that can revolutionize the way businesses process deals.
If you’ve been following this series on blockchain, you now know blockchain’s disruption beyond bitcoin, how that disruption is affecting different industries, and how to get yourself ready for that cross-industry disruption. Now, it’s time to delve into another exciting application of blockchain: smart contracts. Smart contracts are a transformative new technology that can revolutionize the way businesses process deals.
So What’s Ethereum, Anyway?
Simply put, Ethereum is a cryptocurrency you can use to build “smart contracts.” You may be thinking, if contracts start getting smart, how long do I have my job as a lawyer? Spoiler alert: The term “smart contracts” is a mis-descriptive term, at least to some extent. Smart contracts are neither “smart,” nor really “contracts,” at least not in the classic sense of the word! First, we must explore the concept of “trust” and the related concept of “permanence.” Then, we will discuss the word “contract.” Understanding these terms is the secret to understanding “smart contracts” and harnessing their power.
Blockchain-powered computer programs promise to revolutionize the digital economy, but new research suggests they’re far from secure.
Computer programs that run on blockchains are shaking up the financial system. But much of the hype around what are called smart contracts is just that. It’s a brand new field. Technologists are just beginning to figure out how to design them so they can be relied on not to lose people’s money, and—as a new survey of Ethereum smart contracts illustrates—security researchers are only now coming to terms with what a smart contract vulnerability even looks like.
An eclipse attack is a network-level attack on a blockchain, where an attacker essentially takes control of the peer-to-peer network, obscuring a node’s view of the blockchain.
In a new paper titled ” Low-Resource Eclipse Attacks on Ethereum’s Peer-to-Peer Network ,” Sharon Goldberg, an associate professor at Boston University; Ethan Heilman, a Ph.D. candidate at Boston University; and Yuval Marcus, a researcher at the University of Pittsburgh, describe a way to carry out an eclipse attack on the Ethereum network.
(The researchers disclosed their attacks to Ethereum on January 9, 2018, and Ethereum developers have already issued a patch – Geth v1.8.1 – to fix the network.)
In speaking with Bitcoin Magazine , Goldberg explained the research, how it compares to Bitcoin eclipse attacks and why she thinks the work is important.
First, she emphasized that working with Ethereum developers to fix the vulnerability was a smooth process. “It was a very functional, easy disclosure,” she said.
The potential applications for blockchain technology are seemingly endless. Every day a new startup applies distributed ledger technology and smart contracts that underlie cryptocurrencies to a different world scenario offering new and innovative ways to streamline existing systems. Islamic charitable endowments, called waqf, are the latest to get the blockchain treatment.
According to reports Singapore based fintech firm Finterra has developed a crowdfunding platform that uses blockchain to create smart contracts that would be linked to specific waqf projects. A waqf typically involves donating a building, plot of land, or other assets for Muslim religious or charitable purposes with no intention of reclaiming the assets. The concept dates back over a thousand years peaking during the Ottoman Empire.
The DragonChain project has quickly taken the world by storm in the past few months. This Disney-backed blockchain venture has a lot of potential, assuming the team can get their business in order. The project has been lauded as being the “most secure, flexible, and business-ready blockchain platform.” It is quite a high expectation to live up to, but there is no reason to think this particular project can’t succeed.
DRAGONCHAIN IN A NUTSHELL
There are a lot of business opportunities to explore when it comes to blockchain technology. DragonChain positions itself as a solution which allows users to retain complete control of their data. Sensitive business logic and smart contract functionality will be kept proprietary, for obvious reasons. The platform will operate in a scalable and serverless fashion where established programming languages are compatible from day one. This will certainly be appealing to developers looking to get involved with DragonChain and its features.
