Consensus Décentralisé - Blockchains - Smart Contracts - Decentralized Consensus

Consensus Décentralisé - Blockchains - Smart Contracts - Decentralized Consensus | cross pond high tech | Scoop.it
From www.scoop.it - February 17, 2016 5:54 AM

I have decided to offload "Cross Pond High Tech" that may have been perceived recently as being crowded with too many Bitcoin / Blockchain curated links, and have created a new topic dedicated to Decentralized Consensus. It will be both in French and English and is at present managed by several curators including @CHECy and others.

The goal is to build it as a reference repository for e-Litterature on this fast morphing and still highly speculative topic.

-- Fork de Cross Pond High Tech dédié à Blockchain, Ethereum, aux Smart Contracts et au Consensus Décentralisé en général

Philippe J DEWOST's insight:

You are welcome to susbcribe to this fork of "Cross Pond High Tech" focusing on Decentralized Consensus ; don't hesitate to submit enlightning and quality content. Thank you for your interest and future contributions !

Microsoft Partners With ConsenSys To Use Ethereum To Provide Blockchain-As-A-Service

Microsoft Partners With ConsenSys To Use Ethereum To Provide Blockchain-As-A-Service | cross pond high tech | Scoop.it
From techcrunch.com - October 29, 2015 10:12 AM

The Ethereum project and ConsenSys, the company created by one of the project’s co-creators, have received a huge vote of approval from one of the world’s biggest enterprise software providers — Microsoft. The company will be working with ConsenSys to provide development tools for Microsoft’s enterprise customers on the Azure platform.

 

Focusing on financial services we saw a lot of potential for a framework and platform like Ethereum to go across the platform of financial institutions and modernize a lot of processes that were stuck in the past,” says Marley Gray, Director of Technology Strategy, US Financial Services at Microsoft. “We thought that Ethereum was a really good platform for building distributed ledger applications.”

 

Unlike bitcoin-based blockchain applications (and companies like Chain that are developing projects on top of bitcoin) Ethereum uses a different token called the Ether.

 

“Bitcoin offers one functionality which is the monetary functionality. Because it’s a very narrow protocol… it’s difficult to build arbitrarily difficult functionality into the program,” says Joseph Lubin, the founder of ConsenSys, and a major supporter of the Ethereum Foundation.

With Ethereum, there’s a complete computational machine running within every node of the network, Lubin says.

Philippe J DEWOST's insight:

Fragmentation or evolution ? Microsoft's move is interesting anyway and confirms the advent of decentralized consensus as a generic and scalable disruption factor.

Ethereum studio ConsenSys launches 'Internet-of-People' with digital IDs and assets secured on Unbuntu phones

Ethereum studio ConsenSys launches 'Internet-of-People' with digital IDs and assets secured on Unbuntu phones | cross pond high tech | Scoop.it
From www.ibtimes.co.uk - February 9, 2016 2:11 AM

New York City's decentralised apps studio ConsenSys is beginning its "Internet-of-People" campaign with Ethereum-based identity on Ubuntu phones and tablets.

ConsenSys and BlockApps are collaborating with the Ubuntu project's commercial sponsor, Canonical, to deliver web wallet and identity system uPort Biometric Identity tools on Ubuntu devices.

The Nimbus/uPort/Ubuntu proof-of-concept will be unveiled at Mobile World Congress on 22 February, said ConsenSys in a statement.

Nimbus permits users secure interaction with the Ethereum blockchain through biometric protection of cryptographic keys. Through this feature, users will be able to access Ethereum to use decentralised applications (DApps) and develop Ethereum blockchain software.

uPort

uPort represents the next generation of identity systems: the first identity system to enable self-sovereign identity, allowing the user to be in complete control of their identity and personal information, said ConsenSys.

The uPort attestation system allows third-party authorities as well as peers to validate the user's information creating both a rich social fabric as well as powering solid KYC/AML systems in the financial sector. Through uPort's selective disclosure system the user has a total overview over which of their peers, business partners or counterparties can access their information.

Ubuntu

The Ubuntu phone allows total control over the information users distribute online including digital identity. Ubuntu phones and tablets are ideal prototyping tools for building the next generation of mobile blockchain apps as they offer a combined development environment and a testing tool for mobile apps.

As well as inheriting from Ubuntu's security and respect for user's confidentiality, these devices build on strong relation created on the server and cloud side between Ubuntu and Ethereum.

Philippe J DEWOST's insight:

Another move in the Etherealm reminding us how intense the race in decentralized consensus has become, and how critical digital identity management will be to successful deployments.

The Value of Blockchain Technology according to an Ethereum founder

The Value of Blockchain Technology according to an Ethereum founder | cross pond high tech | Scoop.it
From blog.ethereum.org - April 21, 2015 7:35 AM

One of the questions that has perhaps been central to my own research in blockchain technology is: ultimately, what is it even useful for? Why do we need blockchains for anything, what kinds of services should be run on blockchain-like architectures, and why specifically should services be run on blockchains instead of just living on …

Philippe J DEWOST's insight:

Brilliant essay by Vitalik Buterin, one of Ethereum founding members, about what Blockchain is / is not (for).

And his very interesting and generic definition of what a blockchain is:

A blockchain is a magic computer that anyone can upload programs to and leave the programs to self-execute, where the current and all previous states of every program are always publicly visible, and which carries a very strong cryptoeconomically secured guarantee that programs running on the chain will continue to execute in exactly the way that the blockchain protocol specifies.

Notice that this definition does NOT:

- Use financially-charged terms like “ledger”, “money” or “transactions”, or indeed any terms geared toward a particular use case

- Mention any particular consensus algorithm, or indeed mention anything about the technical properties of how a blockchain works (except for the fact that it’s “cryptoeconomic”, a technical term roughly meaning “it’s decentralized, it uses public key cryptography for authentication, and it uses economic incentives to ensure that it keeps going and doesn’t go back in time or incur any other glitch”)

- Make a restriction to any particular type of state transition function

 

I do strongly recommend to anybody interested or curious in this field to take the time to (re)read this post in extenso...
